PSYB45H3 Chapter Notes - Chapter 11: Task Analysis, Adventitiousness, Stimulus Control
Document Summary
Behavioural chain/stimulus response chain: a sequence of stimuli and responses that occur closely to each other in time, with the last response followed by a reinforcer. A sequence of discriminative stimuli (sds) and responses (rs) where each response (except the last) produces the sd for the next response, and the last response is followed by a reinforcer. In a behavioural chain, each sd is: a cue for the next response, and a conditioned reinforcer for the previous response (other than the first sd) Sd1 r1 sd2 r2 sd3 r3 sd7 r7 s+ = reinforcer at the end of the chain. Stimulus response chain - if any response is not produced by the sd before it, the chain is broken. Total-task presentation: attempt all steps of the chain on each trial, continue until every step of the chain is mastered, prompting is used as needed, reinforcement is given upon completing the last step correctly.
