Document Summary
Latent learning= learning takes place without any initial evidence that learning has occurred. Habituation= decrease in strength/ occurrence of a behavior after repeated exposure to the stimulus that produce the behavior. Acoustic startle reflex (asr)=defensive response to loud and unexpected noise. Orienting response= an organism natural reaction to novel stimulus. Fixation time= the duration of staring, decrease with repeated presentation. Advantage of habituation= avoid wasting time and energy on an elaborate response to every repeated event. The more similar the stimulus is, the less the fixation time increase (stimulus generalization). Dishabituation=the renewal of responding after a new stimulus presented. Factors influencing the rate and duration of habituation. Rapid repetition=more rapid habituation (massed exposure= repeated closely together; spaced exposure= spread out overtime) Short term habituation= goes away in several mins and hours/ long term habituation. Spontaneous recovery= the reappearance/ increase in strength of a habituated response after a period of no stimulus presentation.
