PSYB45H3 Chapter Notes - Chapter 11: Backward Chaining, Adventitiousness, Task Analysis
Document Summary
Chapter 11: getting a new sequence of behaviours to occur with behavioural chaining. The reinforcer at the end of a chain maintains the stimuli in the chain as effective sds for the responses that follow them (and as discussed later, as effective conditioned reinforcers for the responses that precede them) But this general sequence consists of a variety of activities (reading, memorizing, writing, etc. ) with many breaks in the action. It is not made up of a consistent series of stimuli and responses that occur closely in time and for which each stimulus (except the last) is an sd for the next response. Consider the way a child might be taught to say milk: he or she may at rst be taught to say m , then mi , then. Because shaping or fading is used, the procedure is still a gradual change procedure: see table 11 2 page 138 for a comparison of shaping, fading, and chaining.
