The Royal Society in the V&A



  In 2010, the Henry Cole lecture
  also celebrates the 350th
  anniversary of the Royal Society


  I am honoured to have been invited
  as a Fellow of the Royal Society to
  deliver this year's lecture



                          British Galleries: 1660 Charles II
Friday, 20 May 2011
First have to explain why I am giving this third Henry Cole Lecture.
And it is all to do with the 350th Anniversary of the Royal Society,
and with the V&A’s idea that a Fellow might say something that could be relevant to museum education.
But there are already connections between the RS and the V&A.
In the British Galleries of the museum you can see a variety of objects related to the founding years of the RS.
Here is a splendid bust of Charles the second, who granted a Royal Charter to the Society, which was founded in November 1660 in London.
I have no special talent
       I am only passionately
       curious




       Albert Einstein FRS

        Royal Society Portrait Collection
Friday, 20 May 2011
Here is a portrait of a famous FRS: Albert Einstein, as you probably don’t know him. This portrait hangs in the RS which also houses a magnificent
collection of portraits and archives.
The RS has a Centre for the History of Science and continuously uses objects from its collections for exhibitions.
The reason I have chosen this portrait is the quote: “I have no special talent. I am only passionately curious.”
If it were not presumptuous I would like to say the same about myself.

There are direct connections between Science and Art right at the foundations of the V&A.
Here is the original entrance to the original building at the back of the Madejski Garden. The reliefs symbolise Science on the left, and Art on the
right, because the museum was originally devoted to both.

Friday, 20 May 2011
Although the museums were split into those for Science, across the road, and here, for Art and Design, connections remain. Not only in the proud
ceramic staircase leading to the National Art Library with its symbolic figures of art and science, but also in the tradition of the V&A’s world leading
and vibrant centre for museum education. I am delighted that this centre applies scientific methods to test and validate its approaches to learning
in a museum environment. This lecture is proof that the V&A takes seriously the possibility that neuroscience can offer insights to education that
are worth considering.

         “By proper arrangements a Museum may be made in the
         highest degree instructional. If it be connected with lectures,
         and means are taken to point out its uses and applications, it
         becomes elevated from being a mere unintelligible lounge for
         idlers into an impressive schoolroom for everybody."
Friday, 20 May 2011
Henry Cole himself was keenly aware of the educational function of the museum. Here is a quote that could not be more to the point:
By proper arrangements a Museum may be made in the highest degree instructional. If it be connected with lectures, and means are taken to point out its uses and applications, it
becomes elevated from being a mere unintelligible lounge for idlers into an impressive schoolroom for everybody."
Given that the museum is a “schoolroom for everybody”

         What insights can neuroscience contribute?



         What goes on in the mind of people who visit the museum?

         If we knew - what would it mean for museum education?




Friday, 20 May 2011
In this lecture tonight I want to explore some of the insights that neuroscience might contribute to museum education. The guiding principle for the
selection of such ‘insights’ has been the question, put to me by Morna Hinton, the director of the Sackler Centre:
“What goes on in the mind of people who visit the museum?”
Outline of the talk
       Things that matter in museum education

          • Teaching others and learning from others
          • Trust matters
          • Intentions: Why a work was created
          • Actions: How a work was created
          • Authenticity matters
          • Value matters
          • Expectation matters
          • Exploration and exploitation
          • Curiosity
Friday, 20 May 2011
Here are the main points that I would like to at least address tonight. They all seem to me to open a window into the mind of the museum visitor.
1. Teaching and learning are profoundly social activities.
2. We don’t learn equally from any teachers, but from those we trust.
3. When we look at a piece in a museum, our brain, quite unbeknown to ourselves, cannot help but ask, why the work was created and how it was
created.
4. When we appreciate objects in a museum, then we take into account, again quite unconsciously, the authenticity of the object, and the
immaterial value of the object, which is regardless of its material value.
5. We see what we expect to see and need guidance in this from experts.
6. We need a balance between exploration of the new and exploitation of the familiar.
7. Finally, I will address the title of this talk - why do we have a curious brain?
The museum is like a brain
It stores cultural memories and it processes cultural information
        The Brain
        the most complex
        structure
        in the world


        The V&A
        the greatest and most
        comprehensive
        treasure house
        in the world
                                                                               4.5 million objects in V&A

Friday, 20 May 2011
Let me start with a metaphor of the museum as a brain of society.
Like in the real brain, most of the work goes on in a hidden world that the visitor hardly ever sees. This includes many specialist staff and many
specialist services, rooms and technical facilities.
The conscious part of the brain can be compared with the public galleries that are on view for the visitor, the place where communication happens
with other beings. In the case of the museum, these other beings may be long dead, but are still present in their works. They are still
communicating with us. This in fact is the miracle of culture. The knowledge of previous generations is not lost but can be built on. Their ideas of
beauty, function and design, shape and feed our own ideas.
Human beings are the only species who teach deliberately



 Our brain has a natural disposition to
 teach and to learn from being taught
                                        Csibra & Gergely, TICS 2009

                Not all teaching is formal

Human beings are the only species who teach deliberately. We are born to teach as well as to learn. If the signals are present, then we can’t help
but learn. These signals are social: a direct glance, a pointing finger, a raised voice. They tell the brain to prepare for a message that is relevant
and that deserves attention. What you learn in these informal social situations are general truths, rather then particular facts. In a formal context,
for example, in a lecture, or when reading a label in the museum, you can learn about particular facts, - provided of course that you pay attention!
Parts of your brain may not be convinced that what you hear is relevant.
We learn by observing others
      • We don’t have to make our own mistakes                                                      Rendell et al. 2010 Science


      • We learn from others not only by observing people and interacting
        with them but also by observing objects made by them

                                                                                    How can objects teach us?
                                                                                • WOW - some objects (the way
                                                                                  they are placed) can’t fail to

                                                                                • GETTING INSIDE - objects are

                                                                                  learners can perceive the
                                                                                  essence: the why and how

Learning is profoundly social. We don’t need to make our own mistakes, we can learn by observing others. We can learn by observing the objects
others designed and manufactured for us. But how can objects signal to our brain that there is a relevant communication that is best attended to?
First, objects can by their features or their placement attract attention willy-nilly. But this is rarely enough. The attention opens a channel for
deeper communication. The museum visitor has become curious: automatically the brain asks, well below our awareness:
 Why this object? How was this object made?
Social pressures in museum education
       We like what others like




 Three-year-olds choose novel toys, foods, games, clothes
 endorsed by same age, same sex peers
                                                                               Shutts, Banaji & Spelke, 2009, Dev Sci


                Adolescents are even more influenced by peer choices
Friday, 20 May 2011
How do we know if we like an object in the museum? How does the brain compute liking? Many factors enter into this computation, which is far too
complicated to enter our awareness. One factor has been studied in the laboratory and I am sure museum educators have long known about it. We
like what others like. This is true for 3-year olds, but perhaps even more so for adolescents, who are strongly influenced by what their peers like.
As adults too we are strongly influenced by knowing, for example, what a celebrity likes. You may be more independent and dislike another’s
favourites. And there are the few who act as leaders of style and taste. These leaders were very prominent in building the original collections of the
V&A.
Trust matters




    Lyons, Young & Keil, 2007 PNAS

Friday, 20 May 2011
How do you become a leader of style? For a young child, you just have to be an adult who can be trusted.
Learning from a trusted source

   Children copy adult’s wasteful strategy in opening puzzle box. They assume adult
   must have a good reason: “This is the way to do it”.



   She trusts the adult                                                                                               He doesn’t

Friday, 20 May 2011
There is a strange mystery. 3 and 4-year olds copy all the actions, including completely unnecessary silly actions, when made by an adult while
opening a puzzle box to retrieve a small toy. The children go through the motions even when told they should just retrieve the toy without any silly
actions. They go through the motions even when there is a competitor who reaches straight for the toy. This is over-imitation.
Chimpanzees always reach straight for the toy. They are not taken in by the unnecessary actions. Over-imitation is an example of how the human
brain learns from others not just efficient ways to reach a goal, but also inefficient ways of action. These actions are ‘the proper way we do things’.
They are in the design of the object.
Trust matters
    •Children overimitate because they trust the actions that
     they see the adult performing more than they trust their
     own senses: the brain is automatically ready to do this.

    •Adults do this too. They learn from people they trust.

    •Trust has to be earned. It can easily be lost.

    •Museums have built up enormous social capital in trust

    •This enhances their role and success in teaching


Friday, 20 May 2011
Overimitation is to do with learning from a trusted source. It is a primary tool for cultural transmission.
It is not only children who over-imitate. When we make objects watching experts we often unconsciously adopt their ways of doing things; the way
to achieve the aim can become even more important then the aim itself.
But, this mechanism depends on trust.
Museums embody trust. This trust has been earned through years of work on collecting and showing authentic objects, and on communicating the
outcome of verifiable research. This enhances the museum’s role and success in education.
Which is the real Rembrandt?
               Once you know - you let go of your liking of the other portrait
               ‘like a former lover no longer blinded by love’

               Martin Kemp, Nature 461 October 2009, p 882 Images Bridgeman Art Library
Friday, 20 May 2011
Trust can be lost when a museum exhibits a fake. As soon as a fake is revealed the museum visitors will cease to like it, even when they did like it
before.
Culture shapes what we enjoy looking at
     • Our brain is not a camera                                      Richard Gregory Eye and Brain 1966, 1997


     • What matters is not the thing as it appears to our senses

     • What matters is what we think a thing really is

     • What matters is why a thing was made and how it was made
       the object’s history: the intentions of the person who created it
       the techniques that were used to make it

     • Our likes and dislikes are influenced by our beliefs and our trust in
       others telling us about the why and how



Friday, 20 May 2011
How come that we can so quickly like and dislike the same object?
Our brain is not a camera that simply takes in information. This information is the same before and after we change our liking. Instead our brain
puts out information and matches this against the input it receives from the senses. The brain has some preconceived notions about what an
object is and why it might be in the museum.
Our beliefs feed these preconceived notions. We tend to get these beliefs from other people, often without being aware of this, by social contagion.
In the museum we can get beliefs not through the backdoor, but through informed guidance of our senses by curators, guides and the labels they
make. Why and how an object was made and the object’s history.
‘Why it is done’ matters



         Beliefs and intentions behind the work

Friday, 20 May 2011
Our brain is constantly searching for evidence about the intentions of other people. When we see a work of art we are influenced by the intention
to create the work even more than by its appearance.
There is more to artwork than its current material
       nature
     • Even for 3-year olds


     • They name pictures on the basis of
       intent - not shape


     • Child will not name lollipop a
       balloon even if they look the same

                                                                               This is a                     This is a
     • Because it is meant to be a
       lollipop                                                                lollipop                      balloon



          Bloom & Markson 1998 Psych Sci
Friday, 20 May 2011
The appearance of two drawings by 3-year-olds can be almost the same. But, to the child who drew these shapes, there is a world of difference.
The child intending to draw a balloon will not accept it to be called a lollipop and vice versa. The drawing is what it is meant to be, not what it
looks like.
Theory of mind: Attributing intentions and beliefs

       • The brain is spontaneously taking into account intentions and beliefs
         (our own and those of others) without our being aware of it.


       • Even when looking at an object in the museum


       • Even more so when we observe an artist creating something


       • Even more so when creating art ourselves




    Individuals with autism
    are not able to spontaneously attribute intentions and beliefs
                                  Baron-Cohen, Leslie & Frith, 1985 Cognition
Friday, 20 May 2011
The brain’s sensitivity to intentions is part and parcel of its disposition to attribute intentions, desires and beliefs to other agents. This is quite
spontaneous and does not stop when considering objects that were made by other agents.
We know from the study of autism that in this condition, where the brain develops abnormally, the spontaneous ability to attribute intentions to
others is missing.
What is it like not to spontaneously
                             attribute intentions?

     Can autistic children remember their
   own intention after they did a drawing?

      Can they remember another person’s
                              intention?

Autism teaches us what it is like not to be able to attribute intentions spontaneously.
Here is a brief experiment that asked the question: Can autistic child
lren remember their own intention after they did a drawing? And can they remember another person’s intention after they too did a drawing?

Friday, 20 May 2011
 This is what the experimenter said: draw one of these airplanes. They were identical except for their colour. However, the child was only given a black pencil.
Later, from memory child has to say which


                airplane she intended to draw


                Child must recall own intention


                E.g. the red airplane




                Same again when experimenter


                did the drawing


Friday, 20 May 2011
 Later on the child was asked: which airplane did you draw? There were no visible signs of intention. The intention had to be retrieved from memory.


 The same question was also asked about a drawing made by the experimenter. The experimenter indicated her intention by gazing at one of the airplanes.
Autistic children have difficulty recalling even their own

 The results show very clearly that 6-year-old children were well able to recall their own intention, and that of the adult.
 This was not the case for the 11-year-old autistic children. And this was not due to general memory failure.
 It is hard to imagine what it means not to be able to attribute, monitor and remember your own intentions - or those of other people. The autistic person has
 severe problems in social communication. For ordinary people communication is made easy precisely because we take account of intentions, desires and
 beliefs. Sometimes this is called having a Theory of Mind. But of course, it is an unconscious process, and not like having a theory at all.
‘How it is done’ matters




          Physical actions behind the work

It is not only the invisible intentions that the brain is trying to pick up when perceiving a work of art, but also the physical actions needed to bring
it about.

 An important discovery about brain mechanisms are so-called mirror neurons in the monkey, and mirror systems in the human brain.
 The brain spontaneously links observed and performed actions.
 This means coding motor output and visual input via the same neurons.
The brain’s mirror system links perception and
       action

       • The same neurons fire when we do the action ourselves

Mirror neurons fire when we see an action being done by another person.
The same neurons fire when we do the action ourselves.
This means there is the opportunity for learning through doing and watching others doing things.
The mirror system allows us to align with others

It is not only actions we mirror, but also emotions. This brings about the spontaneous tendency for groups of people to align themselves with each

Reward matters




  The brain predicts what is going to happen and
  values outcomes accordingly

  Unexpected rewards are valued most highly
                                                                              Schultz & Dickinson, 2000 Ann Rev Neurosci
Friday, 20 May 2011
The brain learns from predictions. It predicts how rewarded it will be by an action. It does this constantly and this is a main engine of learning and
remembering. We are particularly pleased by unexpected rewards. These have high value.
Authenticity matters




Friday, 20 May 2011
We now come to an aspect of museum culture where museums hold a sort of monopoly. Even if museum visitors use the many websites of the V&A
extensively, including the wonderful facility that allows you to browse the collections, people expect the real thing to be in the museum when they
visit. I am reminded of bank notes which by themselves are worthless paper, but they have the Bank of England endorsement: ‘I promise to pay the
bearer on demand the sum of Twenty Pounds’. I would guess however, that banks nowadays rank far lower in trust than museums.
Authenticity matters - even in early childhood



   • 3-year-olds prefer to keep the original
     toy they brought in, not the copy
       “Because it’s mine”                                        A ‘copying machine’ presents the identical toy


   • 6-year-olds value (in tokens) a spoon
     over its copy “Because it once
       belonged to Queen Elizabeth”


   • More value is seen in hidden and
     immaterial property of special objects

Friday, 20 May 2011
An experiment was done in collusion with parents of 3 and 4-year old children. Some of these children had an object they were very attached to
and others did not. They brought these objects into the lab.
The experimenter pretended to have a perfect copying machine. He copied the objects. Then he let the children choose which one they would take
home.
The children who were very attached to the object choose the real object.
Six-year olds also preferred a real object over a copy when it had an association with a special person.

Here is an experiment for you to do. You are allowed to take one perfect duplicate away. Would you happy to have the duplicate of the silver box
that belonged to Edward Jenner, the pioneer of smallpox vaccination? I don’t think so. You know the real thing is directly connected with Jenner, but
the copy is not. Concerning the gold box, you might be happy with a duplicate. The original owner does not perhaps mean that much to you, but
gold is gold. I propose that the original silver box signals a higher value than the original gold box.

There are also effects from lack of authenticity. And they are very negative. Cary Grant and Grace Kelly in Hitchcock’s comedy ‘To catch a thief’ are
not what they seem.
Lack of Authenticity

An experiment was conducted where students at an American University were given either genuine or fake Chloe sunglasses.

In this experiment participants were presented with pairs of pop songs and always choose one that they would like to take away. When they got the
song they wanted they were of course pleased and this was reflected in brain activity. But brain activity was much enhanced when (trumped-up) DJ

Here are some more details of the experiment. Presumably you are pleased when museum experts choose the objects that you like too. The idea
for museum experts to contrast objects of bad taste with objects of good taste objects would give a similar amount of pleasure to you if you
agreed. Exactly this idea was tried by Henry Cole with his cabinet of horrors. This has been explored by Christopher Grayling in the first Henry Cole
lecture (V&A publ. 2010): http://bit.ly/jk0kmf

A strange experiment was conducted at a Subway Station in Washington. The famous violinist Joshua Bell was persuaded to turn up one morning
and play. No crowd gathered. Not many coins were given. But many of the commuters who did not stay to listen would have paid hundreds of
dollars to hear Bell play in concert.
They would have heard the same violinist and the same piece. But they could not value the performance without the knowledge.
Our brain is not like a camera

       • We perceive what we know. We guess, and send out probes to test our
         prediction. Unconsciously.


       • When our prediction turns out to be wrong, we get interested


       • We learn from prediction errors


       • We need some knowledge to start with

Finally, what is curiosity? Is it a good thing?
Curiosity lights up reward centres in the brain


  You will pay token for answer
        to quiz question

   Curiosity is linked to reward
       value of information
   And enhances learning from
         new information



 Brain regions showing higher activity to questions that arouse curiosity
 These regions are associated with reward and connect to regions which are
 crucial to learning and remembering new information

Curiosity is not only visible in the brain. But Kang and colleagues also showed that the size of the pupil is an index of curiosity.
The most curious showed the biggest response
       when they could see the answer to a question they did not know


                                They also remembered the answer

Friday, 20 May 2011
There was a quiz game. The most curious people showed the biggest response in their pupil size, when they could see the answer to a question
they did not know. The interesting thing is that they also later remembered the answer better for just those quiz questions they were curious
about.
Explore vs exploit



    People exploit when they consistently choose the same option,
    believing it yields the highest rewards;
    they explore if they try new options, looking for something better.

Being curious leads us to explore. The counterpoint is to exploit.
Not idle curiosity - but harvesting resources
          Imagine you and your tribe find a fruit tree.
          Hurray. You stay and eat. But, when is it
          time to move on?

          Some members of the tribe might be more
          inclined to explore than others. There is a
          cost to exploring.

          Exploiting is governed by reward systems
          of the brain
                                                                      In the museum: Explore.
          Exploring is governed by controlling and                    Then familiarise yourself
          planning systems of the brain                               with the place you found.
                                                                      After a while you need to
                                                                      go off exploring again.

Curiosity is not idle. It has an evolutionary function in foraging.
The exploring brain                                                               Controlling neurons are active

                                                                                                            Explore = red



                                                                                                            Exploit = blue


                                Frontopolar Cortex

                                                                                                            Explore = red



                                                                                                            Exploit = blue

                               Intraparietal cortex


                                                               Daw, O’Doherty, Dayan, Seymour, Dolan, Nature, 2006

Exploration means that the controlling neurons in the frontal and parietal parts of the brain are active.
Exploitation has a reverse effect and activity in these regions of the brain decreases.
Boredom


      • If we perform a task very out of
        line with the level of our skill
        we are bored

      • Boredom signals that some more
        rewarding task exists

      • The right response is to explore




                                                                                      V& A Watercolour J E Millais ca 1864
Friday, 20 May 2011
Perhaps the time has come for me to sense that you might get as bored as the girl in the picture who is sitting through her ‘second sermon’.

There needs to be a balance between exploration and exploitation. Boredoam is a signal that we should get ready to explore.
What insights from neuroscience for
       museum education?

       • Learning from others includes learning from objects in the
         museum
       • They feed the curious brain
       • We attend to why and how of objects
       • The curious brain propels us to explore
       • We are guided in our exploration by
             • Trust
             • Value
             • Authenticity
             • Prior Knowledge

Summary
Where are inspiration and wonder freely on offer?


             in the museum
             in science


          Thanks to the Royal Society and the V&A




          Thank you for listening

The Curious Brain in the Museum

  • 1. Henry Cole Lecture 2010 The curious brain in the museum Uta Frith FBA, FRS UCL Institute of Cognitive Neuroscience Friday, 20 May 2011
  • 2. The Royal Society in the V&A In 2010, the Henry Cole lecture also celebrates the 350th anniversary of the Royal Society I am honoured to have been invited as a Fellow of the Royal Society to deliver this year's lecture British Galleries: 1660 Charles II Friday, 20 May 2011 First have to explain why I am giving this third Henry Cole Lecture. And it is all to do with the 350th Anniversary of the Royal Society, and with the V&A’s idea that a Fellow might say something that could be relevant to museum education. But there are already connections between the RS and the V&A. In the British Galleries of the museum you can see a variety of objects related to the founding years of the RS. Here is a splendid bust of Charles the second, who granted a Royal Charter to the Society, which was founded in November 1660 in London.
  • 3. I have no special talent I am only passionately curious Albert Einstein FRS 1879-1955 Royal Society Portrait Collection Friday, 20 May 2011 Here is a portrait of a famous FRS: Albert Einstein, as you probably don’t know him. This portrait hangs in the RS which also houses a magnificent collection of portraits and archives. The RS has a Centre for the History of Science and continuously uses objects from its collections for exhibitions. The reason I have chosen this portrait is the quote: “I have no special talent. I am only passionately curious.” If it were not presumptuous I would like to say the same about myself.
  • 4. The original entrance to the South Kensington Museum Science and Art 1857 Friday, 20 May 2011 There are direct connections between Science and Art right at the foundations of the V&A. Here is the original entrance to the original building at the back of the Madejski Garden. The reliefs symbolise Science on the left, and Art on the right, because the museum was originally devoted to both.
  • 5. Science and Art Chemistry Architecture Davy Bramante Astronomy Sculpture Newton Michelangelo Mechanics Painting Watt Titian Friday, 20 May 2011 On the door itself you can see that the 6 panels celebrate 3 pairs of the greatest scientists and artists and put them on equal footing.
  • 6. Science and Art Ceramic staircase decorated with symbolic figures of science and art Sackler Centre the V&A's centre for public learning through creative design and the arts Friday, 20 May 2011 Although the museums were split into those for Science, across the road, and here, for Art and Design, connections remain. Not only in the proud ceramic staircase leading to the National Art Library with its symbolic figures of art and science, but also in the tradition of the V&A’s world leading and vibrant centre for museum education. I am delighted that this centre applies scientific methods to test and validate its approaches to learning in a museum environment. This lecture is proof that the V&A takes seriously the possibility that neuroscience can offer insights to education that are worth considering.
  • 7. Henry Cole & Richard 1854 Redgrave Head of the Schools of Design at South Kensington “By proper arrangements a Museum may be made in the highest degree instructional. If it be connected with lectures, and means are taken to point out its uses and applications, it becomes elevated from being a mere unintelligible lounge for idlers into an impressive schoolroom for everybody." Friday, 20 May 2011 Henry Cole himself was keenly aware of the educational function of the museum. Here is a quote that could not be more to the point: By proper arrangements a Museum may be made in the highest degree instructional. If it be connected with lectures, and means are taken to point out its uses and applications, it becomes elevated from being a mere unintelligible lounge for idlers into an impressive schoolroom for everybody."
  • 8. Given that the museum is a “schoolroom for everybody” What insights can neuroscience contribute? What goes on in the mind of people who visit the museum? If we knew - what would it mean for museum education? Friday, 20 May 2011 In this lecture tonight I want to explore some of the insights that neuroscience might contribute to museum education. The guiding principle for the selection of such ‘insights’ has been the question, put to me by Morna Hinton, the director of the Sackler Centre: “What goes on in the mind of people who visit the museum?”
  • 9. Outline of the talk Things that matter in museum education • Teaching others and learning from others • Trust matters • Intentions: Why a work was created • Actions: How a work was created • Authenticity matters • Value matters • Expectation matters • Exploration and exploitation • Curiosity Friday, 20 May 2011 Here are the main points that I would like to at least address tonight. They all seem to me to open a window into the mind of the museum visitor. 1. Teaching and learning are profoundly social activities. 2. We don’t learn equally from any teachers, but from those we trust. 3. When we look at a piece in a museum, our brain, quite unbeknown to ourselves, cannot help but ask, why the work was created and how it was created. 4. When we appreciate objects in a museum, then we take into account, again quite unconsciously, the authenticity of the object, and the immaterial value of the object, which is regardless of its material value. 5. We see what we expect to see and need guidance in this from experts. 6. We need a balance between exploration of the new and exploitation of the familiar. 7. Finally, I will address the title of this talk - why do we have a curious brain?
  • 10. The museum is like a brain It stores cultural memories and it processes cultural information The Brain the most complex structure in the world The V&A the greatest and most comprehensive treasure house in the world 4.5 million objects in V&A Friday, 20 May 2011 Let me start with a metaphor of the museum as a brain of society. Like in the real brain, most of the work goes on in a hidden world that the visitor hardly ever sees. This includes many specialist staff and many specialist services, rooms and technical facilities. The conscious part of the brain can be compared with the public galleries that are on view for the visitor, the place where communication happens with other beings. In the case of the museum, these other beings may be long dead, but are still present in their works. They are still communicating with us. This in fact is the miracle of culture. The knowledge of previous generations is not lost but can be built on. Their ideas of beauty, function and design, shape and feed our own ideas.
  • 11. Human beings are the only species who teach deliberately Our brain has a natural disposition to teach and to learn from being taught Csibra & Gergely, TICS 2009 Not all teaching is formal V & A Hochhauser Auditorium V & A Museum Education Friday, 20 May 2011 Human beings are the only species who teach deliberately. We are born to teach as well as to learn. If the signals are present, then we can’t help but learn. These signals are social: a direct glance, a pointing finger, a raised voice. They tell the brain to prepare for a message that is relevant and that deserves attention. What you learn in these informal social situations are general truths, rather then particular facts. In a formal context, for example, in a lecture, or when reading a label in the museum, you can learn about particular facts, - provided of course that you pay attention! Parts of your brain may not be convinced that what you hear is relevant.
  • 12. We learn by observing others • We don’t have to make our own mistakes Rendell et al. 2010 Science • We learn from others not only by observing people and interacting with them but also by observing objects made by them How can objects teach us? • WOW - some objects (the way they are placed) can’t fail to draw attention • GETTING INSIDE - objects are displayed in context so that learners can perceive the essence: the why and how V & A Glass Gallery Friday, 20 May 2011 Learning is profoundly social. We don’t need to make our own mistakes, we can learn by observing others. We can learn by observing the objects others designed and manufactured for us. But how can objects signal to our brain that there is a relevant communication that is best attended to? First, objects can by their features or their placement attract attention willy-nilly. But this is rarely enough. The attention opens a channel for deeper communication. The museum visitor has become curious: automatically the brain asks, well below our awareness: Why this object? How was this object made?
  • 13. Social pressures in museum education We like what others like Three-year-olds choose novel toys, foods, games, clothes endorsed by same age, same sex peers Shutts, Banaji & Spelke, 2009, Dev Sci Adolescents are even more influenced by peer choices Friday, 20 May 2011 How do we know if we like an object in the museum? How does the brain compute liking? Many factors enter into this computation, which is far too complicated to enter our awareness. One factor has been studied in the laboratory and I am sure museum educators have long known about it. We like what others like. This is true for 3-year olds, but perhaps even more so for adolescents, who are strongly influenced by what their peers like. As adults too we are strongly influenced by knowing, for example, what a celebrity likes. You may be more independent and dislike another’s favourites. And there are the few who act as leaders of style and taste. These leaders were very prominent in building the original collections of the V&A.
  • 14. Trust matters Lyons, Young & Keil, 2007 PNAS Friday, 20 May 2011 How do you become a leader of style? For a young child, you just have to be an adult who can be trusted.
  • 15. Learning from a trusted source Children copy adult’s wasteful strategy in opening puzzle box. They assume adult must have a good reason: “This is the way to do it”. She trusts the adult He doesn’t Derek Lyons http://bit.ly/g8Z0ug Friday, 20 May 2011 There is a strange mystery. 3 and 4-year olds copy all the actions, including completely unnecessary silly actions, when made by an adult while opening a puzzle box to retrieve a small toy. The children go through the motions even when told they should just retrieve the toy without any silly actions. They go through the motions even when there is a competitor who reaches straight for the toy. This is over-imitation. Chimpanzees always reach straight for the toy. They are not taken in by the unnecessary actions. Over-imitation is an example of how the human brain learns from others not just efficient ways to reach a goal, but also inefficient ways of action. These actions are ‘the proper way we do things’. They are in the design of the object.
  • 16. Trust matters •Children overimitate because they trust the actions that they see the adult performing more than they trust their own senses: the brain is automatically ready to do this. •Adults do this too. They learn from people they trust. •Trust has to be earned. It can easily be lost. •Museums have built up enormous social capital in trust •This enhances their role and success in teaching Friday, 20 May 2011 Overimitation is to do with learning from a trusted source. It is a primary tool for cultural transmission. It is not only children who over-imitate. When we make objects watching experts we often unconsciously adopt their ways of doing things; the way to achieve the aim can become even more important then the aim itself. But, this mechanism depends on trust. Museums embody trust. This trust has been earned through years of work on collecting and showing authentic objects, and on communicating the outcome of verifiable research. This enhances the museum’s role and success in education.

Once you know - you let go of your liking of the other portrait ‘like a former lover no longer blinded by love’ Martin Kemp, Nature 461 October 2009, p 882 Images Bridgeman Art Library Friday, 20 May 2011 Trust can be lost when a museum exhibits a fake. As soon as a fake is revealed the museum visitors will cease to like it, even when they did like it before.
  • 18. Culture shapes what we enjoy looking at • Our brain is not a camera Richard Gregory Eye and Brain 1966, 1997 • What matters is not the thing as it appears to our senses • What matters is what we think a thing really is • What matters is why a thing was made and how it was made the object’s history: the intentions of the person who created it the techniques that were used to make it • Our likes and dislikes are influenced by our beliefs and our trust in others telling us about the why and how Friday, 20 May 2011 How come that we can so quickly like and dislike the same object? Our brain is not a camera that simply takes in information. This information is the same before and after we change our liking. Instead our brain puts out information and matches this against the input it receives from the senses. The brain has some preconceived notions about what an object is and why it might be in the museum. Our beliefs feed these preconceived notions. We tend to get these beliefs from other people, often without being aware of this, by social contagion. In the museum we can get beliefs not through the backdoor, but through informed guidance of our senses by curators, guides and the labels they make. Why and how an object was made and the object’s history.
  • 19. ‘Why it is done’ matters Beliefs and intentions behind the work Friday, 20 May 2011 Our brain is constantly searching for evidence about the intentions of other people. When we see a work of art we are influenced by the intention to create the work even more than by its appearance.
  • 20. There is more to artwork than its current material nature • Even for 3-year olds • They name pictures on the basis of intent - not shape • Child will not name lollipop a balloon even if they look the same This is a This is a • Because it is meant to be a lollipop lollipop balloon Bloom & Markson 1998 Psych Sci Friday, 20 May 2011 The appearance of two drawings by 3-year-olds can be almost the same. But, to the child who drew these shapes, there is a world of difference. The child intending to draw a balloon will not accept it to be called a lollipop and vice versa. The drawing is what it is meant to be, not what it looks like.
  • 21. Theory of mind: Attributing intentions and beliefs • The brain is spontaneously taking into account intentions and beliefs (our own and those of others) without our being aware of it. • Even when looking at an object in the museum • Even more so when we observe an artist creating something • Even more so when creating art ourselves Individuals with autism are not able to spontaneously attribute intentions and beliefs Baron-Cohen, Leslie & Frith, 1985 Cognition Friday, 20 May 2011 The brain’s sensitivity to intentions is part and parcel of its disposition to attribute intentions, desires and beliefs to other agents. This is quite spontaneous and does not stop when considering objects that were made by other agents. We know from the study of autism that in this condition, where the brain develops abnormally, the spontaneous ability to attribute intentions to others is missing.
  • 22. What is it like not to spontaneously attribute intentions? Can autistic children remember their own intention after they did a drawing? Can they remember another person’s intention? Frith 2008 A very short introduction to Autism OUP En.wikipedia Friday, 20 May 2011 Autism teaches us what it is like not to be able to attribute intentions spontaneously. Here is a brief experiment that asked the question: Can autistic child lren remember their own intention after they did a drawing? And can they remember another person’s intention after they too did a drawing?
  • 23. Draw one of these airplanes with black pencil No visible sign of intention (Happé, Bloom and Frith, unpublished) Friday, 20 May 2011 This is what the experimenter said: draw one of these airplanes. They were identical except for their colour. However, the child was only given a black pencil.
  • 24. Later, from memory child has to say which airplane she intended to draw Child must recall own intention E.g. the red airplane Same again when experimenter did the drawing Friday, 20 May 2011 Later on the child was asked: which airplane did you draw? There were no visible signs of intention. The intention had to be retrieved from memory. The same question was also asked about a drawing made by the experimenter. The experimenter indicated her intention by gazing at one of the airplanes.
  • 25. Autistic children have difficulty recalling even their own intention 21 six- year-old typically-developing children 100 20 eleven-year-old children with autism % (Happé, Bloom and Frith, unpublished) 75 50 Autistic 25 Can recall Can recall Autistic own adult’s 0 intention Cannot Cannot intention recall recall own adult’s intention intention Friday, 20 May 2011 The results show very clearly that 6-year-old children were well able to recall their own intention, and that of the adult. This was not the case for the 11-year-old autistic children. And this was not due to general memory failure. It is hard to imagine what it means not to be able to attribute, monitor and remember your own intentions - or those of other people. The autistic person has severe problems in social communication. For ordinary people communication is made easy precisely because we take account of intentions, desires and beliefs. Sometimes this is called having a Theory of Mind. But of course, it is an unconscious process, and not like having a theory at all.
  • 26. ‘How it is done’ matters Physical actions behind the work Friday, 20 May 2011 It is not only the invisible intentions that the brain is trying to pick up when perceiving a work of art, but also the physical actions needed to bring it about.
  • 27. The brain’s mirror system Rizzolatti & Craighero 2004 Ann Rev Neurosci Hamilton 2008 QJExp Psych The brain spontaneously links observed and performed actions motor output visual input Friday, 20 May 2011 An important discovery about brain mechanisms are so-called mirror neurons in the monkey, and mirror systems in the human brain. The brain spontaneously links observed and performed actions. This means coding motor output and visual input via the same neurons.
  • 28. The brain’s mirror system links perception and action • Mirror neurons fire when we see an action being done by another person • The same neurons fire when we do the action ourselves V & A Ceramics Studio Friday, 20 May 2011 Mirror neurons fire when we see an action being done by another person. The same neurons fire when we do the action ourselves. This means there is the opportunity for learning through doing and watching others doing things.
  • 29. The mirror system allows us to align with others When we see an emotional expression we automatically activate the relevant face muscles for this expression Dimberg 2000 Psych Sci Friday, 20 May 2011 It is not only actions we mirror, but also emotions. This brings about the spontaneous tendency for groups of people to align themselves with each other.
  • 30. Reward matters The brain predicts what is going to happen and values outcomes accordingly Unexpected rewards are valued most highly Schultz & Dickinson, 2000 Ann Rev Neurosci Friday, 20 May 2011 The brain learns from predictions. It predicts how rewarded it will be by an action. It does this constantly and this is a main engine of learning and remembering. We are particularly pleased by unexpected rewards. These have high value.
  • 31. Authenticity matters Friday, 20 May 2011 We now come to an aspect of museum culture where museums hold a sort of monopoly. Even if museum visitors use the many websites of the V&A extensively, including the wonderful facility that allows you to browse the collections, people expect the real thing to be in the museum when they visit. I am reminded of bank notes which by themselves are worthless paper, but they have the Bank of England endorsement: ‘I promise to pay the bearer on demand the sum of Twenty Pounds’. I would guess however, that banks nowadays rank far lower in trust than museums.
  • 32. Authenticity matters - even in early childhood • 3-year-olds prefer to keep the original toy they brought in, not the copy “Because it’s mine” A ‘copying machine’ presents the identical toy • 6-year-olds value (in tokens) a spoon over its copy “Because it once belonged to Queen Elizabeth” • More value is seen in hidden and immaterial property of special objects Hood & Bloom, 2008 Cognition Friday, 20 May 2011 An experiment was done in collusion with parents of 3 and 4-year old children. Some of these children had an object they were very attached to and others did not. They brought these objects into the lab. The experimenter pretended to have a perfect copying machine. He copied the objects. Then he let the children choose which one they would take home. The children who were very attached to the object choose the real object. Six-year olds also preferred a real object over a copy when it had an association with a special person.

In 1800, "to convince the faithless" Waterhouse vaccinated his four children and two servants. The six were then exposed to smallpox, without ill effect. Friday, 20 May 2011 Here is an experiment for you to do. You are allowed to take one perfect duplicate away. Would you happy to have the duplicate of the silver box that belonged to Edward Jenner, the pioneer of smallpox vaccination? I don’t think so. You know the real thing is directly connected with Jenner, but the copy is not. Concerning the gold box, you might be happy with a duplicate. The original owner does not perhaps mean that much to you, but gold is gold. I propose that the original silver box signals a higher value than the original gold box.
  • 34. Lack of Authenticity has negative effects on social behaviour and ethics These characters are not innocent holiday makers To catch a thief Hitchcock 1955 Friday, 20 May 2011 There are also effects from lack of authenticity. And they are very negative. Cary Grant and Grace Kelly in Hitchcock’s comedy ‘To catch a thief’ are not what they seem.
  • 35. Lack of Authenticity People merely wearing fake designer glasses feel inauthentic. This caused them to cheat more in tests and to be more cynical about the motives of other people Being associated with a counterfeit product increased dishonesty and cynicism Gino, Norton & Ariely 2010 Psych.Sci Friday, 20 May 2011 An experiment was conducted where students at an American University were given either genuine or fake Chloe sunglasses. While they were wearing them they were given some tests and questionnaires. The people who wore the fake sunglasses differed in their responses. They were more likely to cheat in tests and more cynical about the motives of other people when given questionnaires.
  • 36. Experts matter David Bailey’s Box of Pin-ups 1965 Vidal Sassoon Friday, 20 May 2011 The brain needs to have information and prior knowledge to interpret the world. Experts are particularly trusted and can supply the prior knowledge. Here one expert in photography portrays another. Two celebrated stylists of the Sixtees.
  • 37. Experiment where participants could freely choose pop songs they did not yet own When scanned the reward centres of the brain lit up when they obtained the song they had chosen vs one they had not chosen The reward centres lit up even more when the chosen song was one that experts valued more highly Campbell-Meiklejohn et al. 2010 Curr Biol Friday, 20 May 2011 In this experiment participants were presented with pairs of pop songs and always choose one that they would like to take away. When they got the song they wanted they were of course pleased and this was reflected in brain activity. But brain activity was much enhanced when (trumped-up) DJ experts agreed with their choice, and much reduced when they disagreed.
  • 38. The agreement of experts is rewarding Reward Reward areas areas activated activated when you when get what people you want agree with Campbell-Meiklejohn et al. 2010 Curr Biol your choice Friday, 20 May 2011 Here are some more details of the experiment. Presumably you are pleased when museum experts choose the objects that you like too. The idea for museum experts to contrast objects of bad taste with objects of good taste objects would give a similar amount of pleasure to you if you agreed. Exactly this idea was tried by Henry Cole with his cabinet of horrors. This has been explored by Christopher Grayling in the first Henry Cole lecture (V&A publ. 2010): http://bit.ly/jk0kmf

NY Norton concert in Washington DC Friday, 20 May 2011 A strange experiment was conducted at a Subway Station in Washington. The famous violinist Joshua Bell was persuaded to turn up one morning and play. No crowd gathered. Not many coins were given. But many of the commuters who did not stay to listen would have paid hundreds of dollars to hear Bell play in concert. They would have heard the same violinist and the same piece. But they could not value the performance without the knowledge.
  • 41. Our brain is not like a camera • We perceive what we know. We guess, and send out probes to test our prediction. Unconsciously. • When our prediction turns out to be wrong, we get interested • We learn from prediction errors • We need some knowledge to start with Kersten et al. 2004 Ann Rev Psych Friday, 20 May 2011 The idea that prediction errors are the critical ingredient in learning continues to gather support.
