about
what factors cause, prevent, or
withhold various behaviours, while the
question of,
for instance, conscious
motives would be ignored. Where others
would speculate
about such things as
values, drives, or needs, that may not be
observed
directly, behaviorists are
interested in the observable variables
that
affect the type, intensity, frequency,
and duration of observable behaviour.
Through
the basic research of such
scientists as Pavlov, Watson and Skinner,
several basic mechanisms that govern
behaviour have been identified. The most
important
of these are classical
conditioning and operant conditioning.
