Behavior-Change Procedures

A functional analysis shows a student's aggression is maintained by escape from tasks. The BCBA teaches him to hand over a 'break' card, honors each card with a short break, and no longer allows aggression to produce escape. This procedure is

  1. Afunctional communication trainingCorrect
  2. Bdifferential reinforcement of low rates
  3. Ca response-cost procedure
  4. Dnoncontingent reinforcement

Why: Carr and Durand (1985) showed that teaching a communicative response that produces the same reinforcer as problem behavior reduces that behavior; combined with extinction of the problem behavior, this is functional communication training, a form of DRA. Noncontingent reinforcement delivers the reinforcer on a time schedule regardless of behavior. DRL reinforces lower rates of the same behavior, and response cost removes a reinforcer contingent on behavior.

Concepts and Principles

Hair pulling, table slapping, and throwing toys all reliably produce adult attention for a child. Responses that differ in form but share the same effect on the environment are best described as

  1. Aa functional response classCorrect
  2. Ba behavior chain
  3. Ca single response topography
  4. Da stimulus class

Why: A response class is a set of responses grouped by a shared effect or function, here producing attention, even though their topographies differ. A stimulus class groups stimuli, not responses. A behavior chain is a sequence in which each response produces the cue for the next, and a single topography would require the responses to share one form, which these do not.
