Shaping
The reinforcement of successive approximations to the target behavior.
Successive approximations are steps towards the target behavior.
Rules for Shaping
Behavior chain
A sequence of related behaviors, each of which provides the cue for the next, and the last of which produces a reinforcer.
Chaining
The reinforcement of successive elements of a behavior chain.
Forward Chaining
A chaining procedure that begins with the first element in the chain and progresses to the last element.
Start with the first task in the chain.
Backward Chaining
A chaining procedure that begins with the last element in the chain and progresses to the first element.
Always effective than forward chaining
Rules for Chaining
Shaping vs Chaining
In Shaping, each new approximations is reinforced.
In Chaining, reinforcers are provided at the conclusion of the chain.
