Clinical Psychology

specialty in which both genetic and environmental
influences on the development of behavior are
evaluated. Behavioral geneticists have investigated
these influences in a wide range of behaviors and
individual differences, including intelligence, per-
sonality, and psychopathology. Brain imaging
allows a view of both the structure and function

of the brain and is becoming an important com-

ponent in research on psychopathology. Findings

from this relatively newer area of research will

likely influence both our theories and treatments

of a variety of psychological disorders.

Because research is such an important part of all

clinical psychology, we will be discussing research
