Document Summary

Synesthesia: when most of us see letters printed in black. Touch: pressure of a surface against the skin signals its shape, texture and temperature. As a way of measuring this difference threshold, fechner proposed the just noticeable difference, or jnd, the minimal change in a stimulus that can just barely be detected. Feature integration theory: the idea that focused attention is not required to detect the individual features that comprise a stimulus but is required to bind those individual features together (cid:224)anne treisman. Transcranial magnetic stimulation (tms) is a benign technique that involves placing a powerful pulsed magnet over a person"s scalp, which temporarily alters neuronal activity in the brain. Inattentional blindness: a failure to perceive objects that are not the focus of attention. Here fluid carries the wave energy to the auditory receptors that transduce it into electrochemical activity, exciting the neurons that form the auditory nerve, leading to the brain.
