Brightness illusion
WebMar 31, 2009 · Background The perception of brightness depends on spatial context: the same stimulus can appear light or dark depending on what surrounds it. A less well-known but equally important contextual phenomenon is that the colour of a stimulus can also alter its brightness. Specifically, stimuli that are more saturated (i.e. purer in colour) appear … WebJan 23, 2012 · The present findings show that illusions of brightness or lightness can cause pupillary constrictions from an equiluminant baseline. Importantly, the various versions of the illusions resulted in pupillary …

The illusion is created when a person looks at a gradient of light and dark, and sees a band of increased brightness in the middle of the gradient. The band of increased brightness is an illusion, created by the way the human brain processes light …
WebApr 30, 2024 · It is believed that reverse phi illusion is indeed brightness effects, that it occurs when brightness-reversing picture moving across our retina. It can be explained by mechanisms of visual receptive field model, where visual stimuli are summated spatially (a process that is reverse to spatial differentiation). WebIn the brightness-assimilation type of illusions, the apparent brightness changes in the same direction as its surroundings, as if it were assimilating the intensity of its surroundings. Examples of this include the White effect [54] ( Fig. 26.2 C) and the Checkerboard illusion [12] ( Fig. 26.2 D).
