Document Summary

Each s^d in a behavioural chain is: a cue for the next response, a conditioned reinforcer for the previous response (other than the first s^d) Total task presentation: attempt all steps of the chain, repeat until every step is mastered, prompting provided as needed, reinforcement provided upon completing last step. Backward chaining: last step first, then, next-to-last step is taught and linked with last step, on each trial, last step in the chain is reinforced. Forward chaining: initial step first, then, first and second, etc, on each trial, last step that was developed is reinforced. Gradually constructs the chain of behaviours beginning with the final behaviour and working in reverse order. Consistent final behaviour that"s rewarded the next behaviour. Starting with the last behaviour, each behaviour is mastered before learning. Prompts may be provided to encourage the next behaviour in the sequence. Gradually constructs chain of behaviours beginning with first behaviour in chain and working forward.
