Document Summary

Chapter 3: habituation is formed over repeated exposure of weak innocuous stimulus. It can be repeated at massed or spaced. Massed increases intensity over a short period of time; spaced has long lasting effect: sensitization is the increasing reaction to a painful stimulus at every exposure. Question 2: dishabituation is a temporary effect of reacting to stimuli previously habituated to. Although effect can fade quickly (temporary effect is caused by an arousing/novel stimulus : spontaneous recovery is when repetition of stimulus stops, behaviour returns to normal. Question 3: strong stimuli causes sensitization by strengthening motor and sensory neural connection (results in increase of response, weak stimuli causes habituation by weakening motor and sensory neural connection (results in reduction of response) Children who view food advertisements are exposed to food priming; therefore are more likely to be influenced on their behavior and encourage eating. Question 5: novel object recognition is used to distinguish between fatigue and habituation.
