Document Summary
Aversive stimuli are all around us, and can play a major role in controlling our behaviour. We may perform a certain response in order to avoid or stop an aversive stimulus, or we may encounter an aversive stimulus after performing certain responses. Both involve aversive stimuli (something that makes them want avoid something) of some kind. Making certain responses causes the aversive stimulus to be presented. Negative reinforcement negative contingency between the response and the aversive stimulus-performance of the avoidance response will increase over trials positive contingency between the response and the aversive stimulus-performance of the punished response will decrease over trials. Ex) wearing oven mitts to avoid burn when taking out cookies. Ex) stick a fork in a socket, you"d get a very strong shock. The first examination of avoidance behaviour was a study by bechterev (1913) using human participants. After trials fingers was lifted at cs.
