Orienting responses to pleasant stimuli when expecting pleasant or unpleasant events
- 31 Downloads
The aim was to investigate further the effect of more vigorous orienting to stimuli denoting common fears than to neutral stimuli in subjects threatened with shock. In two experiments, orienting responses (ORs) to pleasant and to neutral words were compared. In Experiment I, the subjects were expecting shock and, in Experiment II, pleasant music. In neither experiment were there differences either in the magnitudes or in the habituation rates of the electrodermal ORs. For clarification, there should be control both of the subjective salience of the stimuli and also of the level of expectation.
