Perceptual Learning is the idea that a person who is repeatedly exposed to a certain stimuli or form of information will invoke long lasting and amazing changes in one's ability to respond to their enviroment. Perceptual Learning involves attention weighing, imprinting, differention, and unitization. A person becomes adapted to tasks by increasing the attention paid to important features. Special receptors are developed and become specialized to specific stimuli. Eventually, tasks that originally required detection so several components are accomplished by detecting only one part of it.
