Response reduction through the superimposition of continuous reinforcement: a systematic replication.

Summary

Superimposing a continuous reinforcement schedule temporarily decreased lever pressing in rats. However, rates quickly returned to baseline once the schedule was removed, limiting its use as a long-term rate-decreasing procedure.

Area of Science:

  • Behavioral psychology
  • Animal behavior research
  • Operant conditioning

Background:

  • Continuous reinforcement (CRF) and its removal may function as a rate-decreasing procedure.
  • Previous clinical research suggests potential efficacy.
  • Laboratory studies indicate rapid recovery of baseline rates after CRF removal.

Purpose of the Study:

  • To investigate the effectiveness of superimposed continuous reinforcement (CRF) as a rate-decreasing procedure.
  • To examine lever-pressing patterns under variable-ratio and variable-interval schedules.
  • To assess the impact of CRF superimposition and removal on established reinforcement schedules.

Main Methods:

  • An A-B-A experimental design was employed.
  • Eight male rats were used as subjects.

  • Lever-pressing was maintained under variable-ratio and variable-interval food reinforcement schedules.
  • A schedule of continuous reinforcement (CRF) was superimposed and subsequently removed.

    • Main Results:

    • Lever pressing was substantially reduced during the superimposition of CRF.
    • Upon removal of the superimposed CRF schedule, responding rapidly returned to pre-superimposition baseline rates.
    • The procedure showed a temporary rate-decreasing effect but lacked lasting impact.

    Conclusions:

    • Superimposing a continuous reinforcement schedule can temporarily decrease response rates.
    • The rate-decreasing effect is transient, with rapid recovery of baseline responding upon schedule removal.
    • CRF superimposition is not a viable long-term rate-decreasing procedure in this laboratory context.
