PSYA01H3 Chapter Notes - Chapter 4: Color Constancy, Detection Theory, Optic Chiasm
Document Summary
Process of detecting and then translating the complexity of the world into meaningful. Process of detecting external events by sense organs and turning experiences in 2 stages: those stimuli into neural signals. Involves attending to, organizing, and interpreting stimuli that we sense (understanding colours, motion and shapes make up image of human walking) When specialized receptors transform the physical energy of the outside world into neural impulses (sensory receptors involved in transduction are different for different senses, table) Doctrine of specific nerve energies separated in the brain (proposed in 1826, johannes m ller) The idea that the different senses are. From evolutionary perspective, our brains evolved to be highly selective to signals of danger and rapidly recognize opportunities for useful resources in environment. The reduction of activity in sensory receptors with repeated exposure to a stimulus (getting used to annoying noise, from being repeated over and over again)
