Purposive behavior, proposed by Tolman, emphasizes that much behavior is goal-directed rather than automatic responses to stimuli. To understand purposive behavior, we must examine entire sequences of actions leading to a goal. For example, athletes follow strict training regimens to achieve fitness goals, and students study hard to reach college admission objectives. This approach highlights cognition's role in learning beyond basic stimulus-response associations.

Expectations, formed through experiences, significantly shape behavior in both classical and operant conditioning contexts. In classical conditioning, individuals learn to expect certain outcomes from stimuli—for example, a child may fear a rabbit if they expect it to cause harm. In operant conditioning, people work hard expecting rewards like paychecks. Expectations can also override actual stimuli, as shown when overweight women who expected to eat desserts ate less after throwing them away.

Incidental learning occurs without reinforcement and is stored cognitively but not immediately expressed in behavior. In Tolman and Honzik's maze experiment, rats explored without food rewards yet later demonstrated they had learned the routes when food was introduced. This finding supports cognition's critical role in learning, showing that organisms acquire knowledge even without immediate behavioral expression or reinforcement.

Kohler's experiments with apes demonstrated that learning involves cognitive problem-solving and sudden insight rather than trial-and-error. In the box problem, apes stacked boxes to reach fruit after moments of contemplation. In the stick problem, they joined two sticks to create a longer tool. These observations showed that apes experienced abrupt understanding of solutions, revealing insight learning as distinct from gradual associative learning processes.

Tolman highlighted that organisms use the conditioned stimulus as a signal to predict the unconditioned stimulus. Leon Kamin's experiment demonstrated this: rats conditioned to fear a tone did not condition to a light paired with the same shock, indicating the rat used the tone as the primary predictive signal. This shows organisms selectively attend to the most informative stimulus rather than conditioning equally to all paired stimuli.

Yes, multicultural experiences significantly enhance insight learning and cognitive flexibility. Studies show that U.S. college students exposed to multicultural slideshows performed better on creativity and insight measures than those viewing neutral content. Time spent abroad or exposure to diverse cultures improves problem-solving abilities. These findings suggest that diverse cultural experiences broaden cognitive perspectives, enabling individuals to approach problems from multiple viewpoints.

The placebo effect illustrates how expectations influence actual physiological outcomes. When individuals expect pain relief from a treatment, this expectation can enhance the actual effect of a painkiller. This phenomenon demonstrates that cognitive expectations are not merely psychological but can produce measurable physical effects, supporting cognitive learning theory's emphasis on mental processes beyond simple stimulus-response mechanisms.
