Document Summary

Learning is a relatively permanent change in behaviour as the result of experience, not maturation . Habituation our responses to repetitive stimuli decrease. Ex. we do not notice our clothing against our skin for a few minutes. Sensitization our responses to novel or salient stimuli increases. Ex. a rustle in the bushes as we walk increases our alertness. But more complex than either adaptation or sensitization. With experience, the sight of lemon salivation. Did work on digestion - subjects were dogs. Won nobel prize for work on digestion. With experience, sight of food salivation. A rat is lever pressing for food. Lever pressing is suppressed during the tone due to conditioned fear. Conditioned response cr (less of cr than ur) Reflexive response to the cs that often resembles the ur. Only forward conditioning works very well and effectively. The cs is presented repeatedly without the us. Suppose the cs is a 500hz tone.
