PSYB65H3 Chapter 6: Sensation and Perception
Document Summary
Sensation: detection of some aspect of a stimulus in the environment. Perception: way in which our brains interpret information gathered by senses. Primary sensory cortex: receives information from senses through thalamus. Secondary sensory cortex: receives information from primary as well as other areas of secondary sensory cortex and sends information to association cortex. Association cortex: receives information from more than one sense. Principles: sensory systems characterized by hierarchical organizations, each level of the organization contains functionally distinct cortical areas, the processing of sensory information occurs in parallel throughout the cortex. Hierarchical organization y where in the hierarchy damage occurs can result in different things. Segregation by function y within each hierarchical level there is separation based on processing of specific aspects of the same stimulus ex. Processing of information in parallel y each level receives some information from level above and below so information flows rapidly and there is less reliance on any one level.
