Document Summary
Reinforcement: process in which behaviour is strengthened by immediate consequence that reliably follows its occurrence that results in strengthening of behaviour. Operant behaviour: acts on environment to produce a consequence and in turn, is controlled by or occurs again in future as result of its immediate consequence. Consequence that strengthens an operant behaviour is reinforce. Positive reinforcement: occurrence of behaviour, followed by addition of stimulus or increase in intensity of stimulus, results in strengthening of behaviour. Negative reinforcement: occurrence of behaviour, followed by removal of stimulus or decrease in intensity of stimulus, results in strengthening of behaviour. Stimulus: object or event that can be detected by one of senses. Positive reinforcer: stimulus presented or appears after behaviour. Aversive stimulus: stimulus that is removed or avoided after behaviour. Social reinforcement: when behaviour produces a reinforcing consequence through actions of another person. Automatic: when behaviour produces reinforcing consequence through direct contact with physical environment.
