Opponent-process theory is a psychological and neurological model that accounts for a wide range of behaviors, including color vision. This model was first proposed in 1878 by Ewald Hering , a German physiologist, and later expanded by Richard Solomon , a 20th-century psychologist.
The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels, each comprising an opposing color pair: red versus green, blue versus yellow ...
In the traditional RYB color model, the complementary color pairs are red – green, yellow – purple, and blue – orange. Opponent process theory suggests that the most contrasting color pairs are red–green and blue–yellow. The black - white color pair is common to all the above theories.
Chromatic value. In 1942, Adams suggested chromatic value color spaces. [2] [3] Chromatic value, or chromance, refers to the intensity of the opponent process responses and is derived from Adams' theory of color vision. [4] [5] [6] A chromatic value space consists of three components: the Munsell–Sloan–Godlove value function: , the red ...

A number of studies looking at physiological and neurological responses support Schmader and colleagues' integrated model of the processes that produce stereotype threat. Supporting an explanation in terms of stress arousal, one study found that African Americans under stereotype threat exhibit larger increases in arterial blood pressure.
Extended parallel process model. The extended parallel process model ( EPPM) is a fear appeal theory developed by communications scholar Kim Witte that illustrates how individuals react to fear-inducing messages. [1] Witte subsequently published an initial test of the model in Communication Monographs.
Habituation. Habituation is a form of non-associative learning in which a non-reinforced response to a stimulus decreases after repeated or prolonged presentations of that stimulus. [1] For example, organisms may habituate to repeated sudden loud noises when they learn these have no consequences.
