Human motor responses to simultaneous aversive stimulation and failure on a valued task . The effects of presentation of an aversive stimulus and simultaneous failure on a bogus intelligence test upon a subject 's aggressive reactions were studied . The subject 's fist clenching was used as an indicator of aggression . Four conditions , generated by the combinations of two kinds of stimulus delivered to the subjects ( aversive or nonaversive ) and two outcomes of the task ( failure or success ) , were investigated . 20 female and 20 male students ( ages : 17-34 years ) were instructed , upon the reception of an aversive or nonaversive acoustic signal , to press with the right hand a device that displayed a slide . Each slide presented an item from an intelligence test , to which the subjects were either allowed to answer successfully ( success ) or not ( failure ) . Failure increased the subject 's autonomic arousal , as measured by photoplethysmographic sensors , in all stimulation conditions , but only the condition with aversive stimulation increased the speed of clenching . This was interpreted as indicating subject 's tendencies to aggression . These results are discussed in relation to the effects of frustration .
