Document Summary

Perception - process of recognizing and interpreting sensory stimuli. Light is reflected and transformed (observer selectively attends to objects, proximal stimulus) Principle of transformation - when stimuli and responses created by stimuli are transformed, or charged, between the environmental stimuli and perception (transduction creating an electrical representation of the tree) Sensory receptors are specialized cells to respond to environmental energy. Transduction occurs, changes environmental energy to nerve impulses. Changes that occur as signals are transmitted through neurons: the behavioural responses: perception, recognition, and action. Primary receiving area: occipital, temporal, and parietal lobes. Experience and action - electrical signals transformed into conscious experience. Coppola (1998) measured relationship between bar orientation (stimuli) and brain activity (physiology) in ferrets. Furmanski and engel (2000) measured behavioural and physiological response to orientated gratings. (a) sensitivity to gratings of different orientations. Highest to vertical and horizontal orientations (b) indicate fmri amplitude to different orientations. Knowledge is any information the perceiver brings to a situation.
