Summary

Fixed-time (FT) schedules and extinction both decrease responding. FT schedules are more effective at reducing response rates when the reinforcer rate differs from the baseline schedule.

Area of Science:

  • Behavioral psychology
  • Operant conditioning

Background:

  • Investigating reinforcement schedules is crucial for understanding behavior modification.
  • Response-dependent schedules are common, but fixed-time (FT) schedules offer an alternative approach.

Observation:

  • This study examined fixed-time (FT) schedules against a baseline response-dependent schedule and extinction.
  • Arbitrary responses were used to evaluate schedule effectiveness.

Findings:

  • Both FT schedules and extinction led to reduced responding.
  • FT schedules demonstrated greater efficacy in decreasing response rates when the FT reinforcer rate was dissimilar to the baseline reinforcer rates.
  • Data analysis explored adventitious response-reinforcer relations to explain these differences.

Implications:

  • Findings suggest that manipulating reinforcer schedules, particularly the dissimilarity of FT schedules to baseline, can be a powerful tool for behavior reduction.
  • This has implications for therapeutic interventions and understanding basic behavioral principles.
