PSYC 2060U Lecture Notes - Lecture 3: Visual Cortex, Likelihood Principle, Retina
Document Summary
Lecture three, perception, psyc 2060u cognitive psychology, matthew shane, What is sensation: sensation: the absorption of raw energy (e. g. , light waves, sound waves) through our sensory organs, transduction: conversion of this energy to neural signals. Why is this important: why is the difference between sensation and perception so important, because perception is not a carbon copy of the real world. Perception is: the process of recognizing, organizing, and interpreting information from senses. World world examples of perceptions: the pupil press, the disappearing dot, the blind spot. No receptors exist where the optic nerve exits the eye. But except under these specially designed conditions, we don"t ever experience a conscious gap in our visual processing. Sensation = the actual raw energy from the environment, being sensed by receptors: we"ve focused on visual stimuli, but the same hold true for all senses. Perception = our conscious interpretation of the sensed energy: not a direct copy of the world.
