PSYB45H3 Chapter Notes - Chapter 11: Reinforcement, Stimulus Control, Task Analysis
Document Summary
Psyb chapter 11: getting a new sequence of behaviours to occur with. Behaviour chain: (aka stimulus-response chain) a consistent sequence of stimuli and responses that occur closely to each other in time and in which the last response is typically followed by a reinforcer. In a behaviour chain, each response produces a stimulus that serves as an sd for the next response. The chain will be broken at the point of its weakest link: repair the chain by strengthening the weak stimulus-response connection by means of an effective training procedure. These sequences consist of a variety of activities with many breaks in between (studying, sleeping, going to class.

Three major methods of teaching a behaviour chain. In chains taught by forward-chaining and total-task presentation, each stimulus (after the first) also eventually functions as an sd for the next response and as a conditioned reinforcer for the previous response.
