Adding timeouts to concurrent schedules reduced extreme response rates in pigeons, approaching indifference as timeout frequency and duration increased. This suggests timeouts influence choice behavior by altering overall reinforcement rates.

Area of Science:

  • Behavioral psychology
  • Animal behavior

Background:

  • Concurrent schedules of reinforcement are used to study choice behavior.
  • Response-contingent timeouts can alter reinforcement rates and influence choice.

Purpose of the Study:

  • To investigate the effects of response-contingent timeouts on choice behavior in pigeons.
  • To examine how timeout frequency and duration impact relative response rates and time allocation.

Main Methods:

  • Four pigeons were exposed to unequal concurrent schedules of reinforcement.
  • Response-contingent timeouts of equal duration and frequency were added to both schedule alternatives.
  • Timeout frequency and duration, as well as postreinforcement blackout duration, were systematically varied.

Main Results:

  • Increasing timeout frequency and duration led to relative response rates approaching indifference.
  • Time allocation showed less consistent variation compared to response rates.
  • Absolute response rates remained unaffected by the timeout contingency.
  • Varying postreinforcement blackout duration did not systematically alter choice measures.

Conclusions:

  • Response-contingent timeouts can modulate choice behavior in concurrent schedules, primarily by affecting overall reinforcement rates.
  • The findings align with previous research manipulating overall reinforcement rates.
  • Intertrial intervals following reinforcement may not be crucial for this effect.
