Choice assessments accurately identify preferences, predicting how well stimuli function as reinforcers. This helps tailor interventions for individuals with severe disabilities by understanding their unique reinforcing values.

Area of Science:

  • Behavioral psychology
  • Applied behavior analysis

Background:

  • Choice assessments are more effective than single-item presentations for identifying preferences.
  • The relationship between preference assessment outcomes and reinforcer effectiveness requires further investigation.

Purpose of the Study:

  • To determine if preference levels identified through choice assessments predict the relative effectiveness of stimuli as reinforcers.
  • To compare the reinforcing effectiveness of high, middle, and low preference stimuli.

Main Methods:

  • A choice assessment was used to categorize stimuli into high, middle, and low preference levels.
  • A concurrent operants paradigm was employed to assess the reinforcing effectiveness of these categorized stimuli across four clients.

Main Results:

Related Experiment Videos

  • High-preference stimuli consistently served as reinforcers for all clients.
  • Middle-preference stimuli were effective reinforcers only when contrasted with low-preference stimuli.
  • Low-preference stimuli did not function as reinforcers when compared to higher preference stimuli.

Conclusions:

  • Choice assessments can reliably predict the relative reinforcing value of stimuli.
  • These findings can inform the development of more effective individualized intervention programs for clients with severe to profound disabilities.
