Document Summary
People who experience synesthesia experience stimulus that typically would be perceived by one sense in most people in two or more sensory modalities. Most common form grapheme-color synesthesia: people see a color in response to a specific letter or number. Sensation: act of using sensory systems to detect environmental stimuli: transforming physical energy from environment into electrical signals transduction. Perception: conscious recognition and identification of a sensory stimulus. Sensory receptor cells: convert specific forms of environmental stimuli into neural impulses, the form of communication used in our brains and nervous system: conversion known as sensory transduction. Absolute threshold: minimal stimulus necessary for detection by individual: anything below the threshold goes unnoticed. Difference threshold (just noticeable threshold): minimal difference b/w 2 stimuli necessary for detection of a difference b/w the 2: ex. Listening to music on ipod and noticing that music got louder.
