Document Summary

Elicited behavior (beh. that"s automatically drawn out by a certain stimuli) Reflex (simple elicited beh. ) (simple automatic response to stimuli) Startle response (defensive reaction to sudden, unexpected stimuli) Orienting response (automatically position ourselves to facilitate attending to a stimulus) Flexion response (automatically jerk away from object we contact by accident) Reflex arc (activates simple reflexes) (neural structure consisting of neurons) Fixed action pattern (fixed sequence of responses elicited by a specific stimulus) Sign stimulus/releaser (stimulus that elicits a fixed action pattern) Habituation (decrease in the strength of an elicited beh. following repeated presentations of the eliciting stimulus) Sensitization (increase in the strength of an elicited beh. following repeated presentations of the eliciting stimulus) Long-term habituation (response slowly decreases a s a result of repeated stimulation) Short-term habituation (response quickly decreases as a result of repeated stimulation) Dishabituation (reappearing of a habituated response following representation of old stimulus)
