Visual Perception Flashcards
Explain the process of visual perception, with reference to reception (visible light spectrum); transduction (photoreceptors, receptive fields); transmission (visual cortex); selection (feature detectors); and organisation and interpretation (visual perception principles).
The process of visual perception invloves two stages: sensation and perception. The first stage, sensation, involves reception, transduction and transmission. The second stage, perception, involves election, organisation and interpretation.
Determine biological influences on visual perception, including physiological make-up, ageing and genetics
Genetics, ageing, eye damage and physiological make-up can all affect how we preceive things
Explain psychological influences on visual perception including:
Perceptual set (past experience, context, motivation and emotional state)
Visual perception principles (gestalt, depth cues and visual constancies).
The perceptual set is one pyschological influence on visual perception. It is a predisposition to perceive stimuli in a specific way because of preconceptions, and is made up of context, past experience, emotion and motivation.
Visual perception principles are another pyschological influence on visual perception. The brain selects and organises visual information based on a number of visual perception principles, including Gestalt principles, depth cues and perceptual constancies.
evaluate the impact of social influences on visual perception, with reference to cultural skills (Hudson 1960; Deregowski 1972; Deregowski, Muldrow and Muldrow 1972).
analyse the fallibility of visual perception, with reference to the Muller-Lyer, Ames room, and Ponzo visual illusions, as well as ambiguous and impossible figures.
The biological and psychological influences on our visual perception can affect how reliable our visual perception is. This is the basis of many visual illusions, including Muller-Lyer, Ames room, Ponzo and impossible and ambiguous figures.
