A contrast effect is the enhancement or diminishment, relative to normal, of perception, cognition or related performance as a result of successive (immediately previous) or simultaneous exposure to a stimulus of lesser or greater value in the same dimension. (Here, normal perception, cognition or performance is that which would be obtained in ...
Behavioral contrast refers to a change in the strength of one response that occurs when the rate of reward of a second response, or of the first response under different conditions, is changed. For example, suppose that a pigeon in an operant chamber pecks a key for food reward. Sometimes the key is red, sometimes green, but food comes with ...
Depending on how the individual categorizes information, contrast effects can occur as well. The more specific or extreme the context stimuli were in comparison to the target stimulus, the more likely contrast effects were to occur. The term assimilation effect appears in the field of social comparison theory as well.

The framing effect is the tendency to draw different conclusions from the same information, depending on how that information is presented. Forms of the framing effect include: Contrast effect, the enhancement or reduction of a certain stimulus's perception when compared with a recently observed, contrasting object. [57]
