The weaknesses in behavioral Theory in psychology was that it
focused more on the effects of stimuli and did not consider individual
differences. Some
of the strengths was that when humans practice learning it was
believed to strengthen it.
Ivan Pavlov's Drooling dog Experiment was when Ivan and his assistants
brought in different types of food to the dogs activating the
salivating response. When they kept repeating
the same thing the dogs did the same thing. He learned that there was
a learned salivation response.
