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 ...
The same accessible information can result in assimilation or contrast effects, depending on how it is categorized. When the accessible information to construct the representation of the target is used, an assimilation effect results, whereas accessible information used to construct the standard of comparison leads to contrast effects.
Contrast effect, the enhancement or reduction of a certain stimulus's perception when compared with a recently observed, contrasting object. [ 58 ] Decoy effect , where preferences for either option A or B change in favor of option B when option C is presented, which is completely dominated by option B (inferior in all respects) and partially ...
Differences in perceptions of sexual interest between men and women may be exploited by both genders. Men may present themselves as more emotionally invested in a woman than they actually are in order to gain sexual access; 71% of men report engaging in this form of manipulation and 97% of women report having experienced this form of manipulation.

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.
The ERN is a sharp negative going signal which begins about the same time an incorrect motor response begins, (response locked event-related potential), and typically peaks from 80 to 150 milliseconds (ms) after the erroneous response begins (or 40–80 ms after the onset of electromyographic activity).
To see whether the training paradigm was successful in modifying approach–avoidance bias, the reaction time when participants are instructed to push away the target stimuli (e.g., alcohol or spider cues) compared to when participants are instructed to push away the comparison stimuli are contrasted, along with the analogous contrast for ...
The Chubb illusion is similar to another visual illusion, the contrast effect.The contrast effect is an illusion in which the perceived brightness or luminance of an identical central visual target form on a larger uniform background varies to the test subject depending on the ratio of the central form's luminance to that of its background.
