Document Summary

Perception and sense of reality are products of evolution. Human senses are limited to certain kinds of energy in nature (therefore, human sense of reality is limited) Cortical remapping: when you lose a sense there is a remapping in the brain based on what is more important. Brain stimulation: tms (transcranial magnetic stimulation), tdcs (transcranial direct current stimulation) Distal stimulus -> environmental stimulus -> attended (proximal) stimulus -> Stimulus on receptors -> transduction -> processing -> knowledge/ perception -> Inside retina -> transduction (taking a form of energy) Chain of excited neurons which leads to perception. Absolute threshold: minimum amount of stimulation necessary to detect a stimulus. Method of adjustment: quick and dirty dial until stimulus is perceived. Method of constant stimuli: presented different intensities and must indicate whether detected again. Staircase method: one up or down from previous trial. Psychophysical scaling: changes in stimulus intensity relate to changes in perceived intensity.
