Perceptual psychology is a branch of science that concerns the subjective aspects of perception, mainly with the processing of received sensory stimuli. With regard to vision, the conditions of receiving visual information are only fully comprehended by extending the physiology of the eye to include the psychology of perception.
Light represents the connecting medium. Lighting is classified and interpreted by human perception.
With vision, perceptual psychology together with the physiology of the eye takes into account all factors in the interplay between
Experience and its resultant expectations are sometimes so strong that missing parts of a shape are added or individual details are perceived as changed in order to modify the object to the expectation.
Here, the principles of constancy phenomena apply as part of visual perception.
In a perspective drawing, the two thick vertical lines seem to have different lengths. This is explained by the fact that the observer interprets the drawing spatially. However, a line that is further away must be larger than a near line to produce a retinal image that is just as large as this near line – the line is therefore interpreted and perceived as larger in the spatial depth with actually identical length.
In perceptual psychology, innate mechanisms and one's own experience play a role. Presumably, the innate component fundamentally organises the perception. At a higher level of processing, the experience helps to interpret complex shapes.
The spatial graph shows the progression of luminance and the interpretive effect of perceptual psychology.
