PSYC 2440 Lecture Notes - Lecture 11: Error Detection And Correction, Backward Chaining, Adventitiousness
Document Summary
Psych 2440 behavior modification principles lecture 10 - chapter 10. A general sequence that consists of a variety of activities with breaks in the action is not a chain. Backward-chaining always has a built-in conditioned reinforcer to strengthen each new response that is added to the sequence. Each stimulus also eventually functions as an sd for the next response and as a conditioned reinforcer for the previous response. Forward-chaining method: teaches the initial step of the sequence first, then teaches and links together the first and second steps, etc until the entire chain is acquired. Gradual change procedures: each involves progressing gradually through a series of steps to produce a new behavior, new stimulus control over a behavior, or a new sequence of stimulus- response steps. Similarities and differences among shaping, fading, and chaining. New stimulus control dimensions such as topography, amount, or intensity.
