Psychology
is the study of behavior - usually human behavior. Within
this broad definition there are many sub-disciplines, for
example:
Social Psychologists consider people's behaviors
as a result of the social situations in which they find
themselves.They may therefore study the effects of groups
on behavior, attitudes, roles, etc.
Biological Psychologists study the structure and
function of the brain in relation to behavior.
Individual Psychologists consider how individual
differences in people affect behavior. They may therefore
study the effect of intelligence or personality on behavior.
Clinical Psychologists are interested in studying
abnormal behavior typically exhibited by sufferers of clinical
disorders; for example, depression, schizophrenia and anxiety.
Comparative Psychologists are interested in the
way animals behave and how their behavior relates to human
behavior.
Cognitive Psychologists study the decision making
processes that lead to behavior. They may therefore study
human thinking, reasoning, memory, learning and perception.
Developmental Psychologists are interested in the
development of different kinds of human behavior through
the lifespan from infants to the elderly.
Organisational Psychologists consider behavior at
work and in organisations. They may study motivation at
work, job satisfaction, decision making, leadership, personnel
selection, and so on.
Health Psychologists are interested in the behavior
of people in relation to their health and well-being. They
may study such issues as stress, illness behavior, and doctor-patient
interactions.
