Behaviorism
Behaviorists believe that psychology
should focus on measureable and
observable physical behaviors and how
these behaviors can be manipulated by
changes in the external environment.
There is no room in behaviorist theory
for thoughts or emotions, a contrast to
other theories of psychology.
