2. Humans, or human beings, are bipedal
primates belonging to the mammalian species
Homo sapiens (Latin: "wise man" or "knowing
man").
Humans have a highly developed brain
capable of abstract reasoning, language, and
introspection.

4.  The cerebral cortex is nearly symmetrical, with
left and right hemispheres that are
approximate mirror images of each other.
Anatomists conventionally divide each
hemisphere into four "lobes", the frontal
lobe, parietal lobe, occipital lobe and temporal
lobe.

6.  Frontal lobe: It is associated with reasoning,
planning, parts of speech, movements,
emotions and problem solving.
 Parietal Lobe: Associated with movement
orientation, recognition, perception of stimuli.
 Occipital Lobe: Associated with visual
processing.
 Temporal Lobe: Associated with perception
and recognition of auditory stimuli, memory
and speech.

7. The human brain perceives the external world
through the senses, and each individual
human is influenced greatly by his or her
experiences, leading to subjective views
of existence and the passage of time. Humans
are variously said to
possess consciousness, self-awareness, and a
mind, which correspond roughly to the mental
processes of thought.

8. These are said to possess qualities such as self-
awareness, and the ability to perceive the
relationship between oneself and
one's environment. The extent to which the
mind constructs or experiences the outer world
is a matter of debate, as are the definitions and
validity of many of the terms used above.]

9.  The philosopher of cognitive science Daniel
Dennett,
for example,
 argues that there is no such thing as a
narrative center called the "mind", but that
instead there is simply a collection of sensory
inputs and outputs: different kinds of
"software" running in parallel.

10.  Psychologist B.F. Skinner
argued that the mind is an explanatory fiction
that diverts attention from environmental
causes of behavior,
 and that what are commonly seen as mental
processes may be better conceived of as forms
of covert verbal behavior.

11.  Like most primates, humans are social by
nature; however, humans are particularly
adept at utilizing systems of communication
for self-expression, the exchange of ideas, and
organization. Humans create complex social
structures composed of cooperating and
competing groups, ranging in scale from small
families and partnerships to species-wide
political, scientific and economic unions.

12. . Social interactions between humans have also
established an extremely wide variety of
traditions, rituals, ethics, values, social norms,
and laws which form the basis of human
society. Humans also have a marked
appreciation for beauty and aesthetics which,
combined with the human desire for self-
expression, has led to cultural innovations such
as art, literature and music.

13.  Man's needs, feelings and desires cause him to
act for his own benefit and without regard for
the needs and wishes of others. Man uses every
means to fulfill his own needs: he uses every
kind of transport to reach his destination; he
uses the leaves, stems and fruit of plants and
trees; he lives upon the meat of animals and
their products, and takes advantage of a
multitude of other things to complement his
own deficiencies in certain respects.

14.  Man co-operates with the social nexus and
gives a certain measure of his own efforts to
fulfill the needs of others; in return he benefits
from the efforts of others in order to full fill his
own needs.
 Thus man's first nature incites him to pursue
the fulfillment of his own needs using others in
the process and taking advantage of their work
for his own ends. It is only in cases of necessity
and helplessness that he lends a hand to co-
operate with society.

15.  In the development of human beings, all three
factors are very important… like in the topic
“man as psychological, biological and social
unit”, these three factors go parallel to each
other..
 Man is incomplete even if one of the above
mentioned factor is missing.
 Biological factors include the inherited
characters, that helps in the development of
human beings.

16.  Some characters are inherited in humans like
aggression, feelings, attitudes, behavior,
emotions, height, color and so on..
 Brain is the central part of human body..
Hypothalamus controls different mechanisms
like secretions of hormones, (endocrine and
exocrine secretions), motivation and moods
and other activities within the body.
 Due to biological presence of brain, the
psychology of human develops that further
leads towards the development of man as a
psychological unit.

17.  Social factors are also important with biological
and psychological factors.
 It includes the systems of communication and
exchange of ideas,
 Social interactions between humans have also
established an extremely wide variety of
traditions, rituals, ethics, values, social norms,
and laws which form the basis of human
society.

18.  Conclusion:
Human’s personality is basically the
combination of all three factors, all go parallel
to each other, any phenomena cannot occurs
separately..
