This theory also explains negative afterimages; once a stimulus of a certain color is presented, the opponent color is perceived after the stimulus is removed because the anabolic and catabolic processes are reversed. For example, red creates a positive (or excitatory) response while green creates a negative (or inhibitory) response.
An afterimage, or after-image, is an image that continues to appear in the eyes after a period of exposure to the original image. An afterimage may be a normal phenomenon (physiological afterimage) or may be pathological . Illusory palinopsia may be a pathological exaggeration of physiological afterimages. Afterimages occur because ...
The observer then perceives a cyan (or magenta) square on the blank sheet. This complementary color afterimage is more easily explained by the trichromatic color theory (Young–Helmholtz theory) than the traditional RYB color theory; in the opponent-process theory, fatigue of pathways promoting red produces the illusion of a cyan square.

Ambiguous images are important to the field of psychology because they are often research tools used in experiments. [3] There is varying evidence on whether ambiguous images can be represented mentally, [4] but a majority of research has theorized that mental images cannot be ambiguous. [5]
The negativity bias, [1] also known as the negativity effect, is a cognitive bias that, even when positive or neutral things of equal intensity occur, things of a more negative nature (e.g. unpleasant thoughts, emotions, or social interactions; harmful/traumatic events) have a greater effect on one's psychological state and processes than neutral or positive things.
Beck suggests that people with negative self-schemata are liable to interpret information presented to them in a negative manner, leading to the cognitive distortions outlined above. The pessimistic explanatory style , which describes the way in which depressed or neurotic people react negatively to certain events, is an example of the effect ...

[1] Negative affectivity subsumes a variety of negative emotions, including anger , contempt , disgust , guilt , fear , [ 2 ] and nervousness .
In the philosophy of mind, neuroscience, and cognitive science, a mental image is an experience that, on most occasions, significantly resembles the experience of "perceiving" some object, event, or scene but occurs when the relevant object, event, or scene is not actually present to the senses.
