PSYB45H3 Chapter 15: Differential Reinforcement
Document Summary
Differential reinforcement of alternative behaviour- behavioural procedure used to increase the frequency of a desirable behaviour and to decrease the frequency of an undesirable behaviour. the desirable behaviour is reinforced each time it occurs, any undesirable behaviours that may interfere are not reinforced. the dra involves combining reinforcement for a desirable behaviour and extinction for undesirable behaviours. Stereotypic behaviour- repetitive behaviours that do not serve any social function for the individual. They function to produce some form of sensory stimulation for the individual. Those with mental retardation may always slap their heads with their hands, body rocking etc. You must answer these three questions before deciding if dra is the right procedure to use: If procedures such as shaping or prompting are used initially to evoke the behaviour, dra may then be used to strengthen and maintain the behaviour.
