Document Summary

The length or complexity of the chain depends on the learner, and the more complex the chain, the longer it will take to learn it. Not all responses in a chain are a ected equally by the reinforcer. In backward chaining, responses at the end of the chain are strengthened more than those at the start of the chain. Both the length of the chain and the nature of the behaviour must be taken into consideration. Stimulus variation is all possible variations of sds likely to be encountered should be included in the training regimen. Response variation is when the variations in sds often require some change in the response to produce the same e ect. Using jelly instead of jam requires di erent responses to get it out of the jar and onto the bread. Gradual change procedures include shaping, fading, and chaining. All three progress gradually to produce a new behaviour.
