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 assimilation effect, also known as assimilation bias, occurs when people judge something as closer to what’s around it, making it blend in with its context. In contrast, the contrast effect happens when people see something as farther apart from its surroundings, highlighting differences instead. These effects are widely studied in ...
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. [58]
Hallucinogen persisting perception disorder (HPPD) is a non-psychotic disorder in which a person experiences apparent lasting or persistent visual hallucinations or perceptual distortions after using drugs, [1] including but not limited to psychedelics, dissociatives, entactogens, tetrahydrocannabinol (THC), and SSRIs.
Contrast is a feature of visual stimuli that characterizes the difference in brightness between dark and light regions of an image. Perception of contrast is affected by the temporal frequency and spatial frequency properties of a stimulus, and the sensitivity to contrast in sine wave stimuli is characterized by the contrast sensitivity function.
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.

The combined concept of behavioral contrast is sometimes also referred to as the Crespi effect. In 1981, Bower discovered that positive contrast may be reduced because the response measure hits a ceiling. Thus, if contrast is the subject of an experiment, reward sizes may need to be adjusted to keep the response below such a ceiling. [5]
