Children's skin conductance responses (SCRs) increase with longer intervals between reinforcements. This suggests that extended periods without rewards may evoke negative emotions in children aged 8-12.

Area of Science:

  • Psychology
  • Behavioral Science
  • Neuroscience

Background:

  • Intermittent reinforcement schedules are common in behavioral conditioning.
  • Skin conductance responses (SCRs) are physiological indicators of emotional arousal.
  • Previous research links reinforcement schedules to emotional and physiological responses.

Purpose of the Study:

  • To investigate the effect of different intermittent reinforcement schedules on children's SCRs.
  • To determine if SCR amplitude varies based on the inter-reinforcement interval.
  • To explore the emotional correlates of reinforcement timing in children.

Main Methods:

  • Two experiments were conducted with children aged 8-12 years.
  • Participants were exposed to varying intermittent schedules of reinforcement.

Related Experiment Videos

  • Skin conductance responses (SCRs) were measured immediately after reinforcement delivery.

    • Main Results:

    • Children's SCR amplitudes were significantly influenced by the schedule of reinforcement.
    • Longer inter-reinforcement intervals led to larger SCR amplitudes.
    • Findings suggest a link between reinforcement timing and physiological arousal.

    Conclusions:

    • The duration of the interval between reinforcements impacts children's physiological responses.
    • Longer intervals may elicit aversively motivated emotions, as indicated by increased SCRs.
    • These findings have implications for understanding emotional regulation and behavioral conditioning in children.
