Document Summary
Song of the day: there is a mountain -donovan. Sensation: basic processes by which sensory organs and the nervous system respond to stimuli in the environment and the elementary psychological experiences that result from those processes. Perception: more complex organization of sensory information within the brain and the meaningful interpretations extracted from it. Synesthesia: the perceptual experience of one sense that is evoked by another sense. Methods that measures the strength of a stimulus and the observer"s sensitivity to that stimulus. The minimal intensity needed to just barely detect a stimulus. According to the theory, there are a number of determiners of how a detecting system will detect a signal, and where its threshold levels will be. The theory can explain how changing the threshold will affect the ability to discern. Transduction: conversion of one form of energy to another, sensory neurons convert physical signals from the environment into neural signals sent to the central nervous system.
