It has been suggested that empathy leads to altruistic rather than egoistic motivation to help. This hypothesis was tested by having subjects watch another female undergraduate receive electric shocks and then giving them a chance to help her by taking the remaining shocks themselves. In each of two experiments, subjects' level of empathic emotion (low versus high) and their ease of escape from...

Four experiments examined motivational effects of response-contingent electric shocks on action initiation. Although the shock was unambiguously aversive for the individual in line with subjective and functional criteria, results showed that the shock-producing action was initiated faster relative to a response producing no shock. However, no facilitation effect was found when strong shocks wer...

The procedure described here involves training an animal to make steady contact with a reward spout in order to receive food or water and then pairing a stimulus with mild electric shock delivered through the spout. The animal quickly learns to avoid the shock by breaking contact with the spout whenever it detects the stimulus. The breaking of contact with the spout is then used to indicate tha...

The case of a pregnant woman suffering a large placental abruption following electric shock at 32 weeks' gestation is reported. No other such cases have been published in the literature.

Do people sometimes seek to atone for their transgressions by harming themselves physically? The current results suggest that they do. People who wrote about a past guilt-inducing event inflicted more intense electric shocks on themselves than did those who wrote about feeling sad or about a neutral event. Moreover, the stronger the shocks that guilty participants administered to themselves, th...
