PSYB57H3 Study Guide - Midterm Guide: Subliminal Stimuli, Visual Cortex, Blindsight
Document Summary
Visual agnosia: inability to identify objects visually event though they can identified otherwise. Blindsight: patients with damage to the visual cortex can make judgements about objects in their. Blind area even if they have no consciousness of the object and are guessing. Perception: processing of sensory information in a way that produces conscious experiences. Weiskrantz theorized that we are able to perceive visual objects even with no conscious experience. Code: a set of rules/operations that transforms items/objects/data from one form to another. Encoding: process and transforming information into different modes of representation. We encode through categories (ex horse -> 4-legged animals -> mammals -> warm-blooded animals. Encoding is largely automatic, unconscious and very fast. Multidimensional encoding occurs when an item is encoded in terms of multiple dimensions (ex physical characteristic, size, shape) Subliminal perception occurs when a stimulus has an effect on behaviour even though it has been exposed too rapidly/too low intensity to identify.
