Document Summary
Behavioural chain: complex behaviour consisting of many component behaviours that occur. Examples of behavioural chains: chewing gum, reach into pocket, pull out pack of gum, pull a single stick out of pack, unwrap piece of gum, put gum into mouth. Each behaviour in the chain can be completed only after previous behaviours in chain have been completed in sequence. Establishing operation making the reinforcer more reinforcing at a certain time, this increases likelihood that you"ll start the behavioural chain (in gum example, stinky breath) Task analysis: process of analyzing a behavioural chain by breaking it down into its individual stimulus-response components. Identify all behaviours necessary to perform task and write them down in order. Identify s^d associated with each behaviour in task. Different ways to conduct a task analysis: observe a competent person engage in the task, ask an expert (a person who performs the task well, perform the task yourself and record each of the component responses.
