The document discusses two programs, FaceGen and Psychomorph, that are used to manipulate facial characteristics. FaceGen was used to create a database of artificially generated faces that varied across dimensions like attractiveness and extroversion. Psychomorph allows users to transform real human faces along the same dimensions by morphing between prototypes. Examples are provided of faces morphed to be more masculine, feminine, trustworthy, and dominant. Videos also demonstrate the transformations in action.

2. 1. CREATING ARTIFICIAL FACES
A Data-Driven Approach
 Torodov et al, 2010 (link) were the first to develop a computational model of social judgements from faces
 Using a program called FaceGen they created a database of faces designed to be maximally distinct from one
another
 These were rated by thousands of participants to provide external validity
 Transformations along all other dimensions are controlled for attractiveness

3. FACEGEN EXAMPLES:
25 ‘INDIVIDUALS’ MORPHED ALONG 7 DIMENSIONS

4. FACEGEN EXAMPLES:
‘INDIVIDUALS’ AND TRAITS
Competence
Dominance
Extroversion
Trustworthiness

5. FACEGEN EXAMPLES:
‘INDIVIDUALS’ AND TRAITS
Attractiveness
(Neutral, Low, High)
Extroversion
(Neutral, Low, High)

6. FACEGEN EXAMPLES:
‘INDIVIDUALS’ AND TRAITS
Competence
(Neutral, Low, High)
Dominance
(Neutral, Low, High)

7. II. PSYCHOMORPH
The problem with artificial faces….
 Computational models can create “maximally
distinct” faces on each dimension
 However, the faces are clearly not real
 To overcome this limitation, we use a set of
algorithms which have been under development
for nearly 20 years (link)
 Psychomorph (now called Webmorph) allows us
to use these prototypes to transform real faces
along the dimensions identified by Todorov
Untrustworthy
Trustworthy
