Waiting in intertemporal choice tasks affects discounting and subjective time perception.

Area of Science:

• Behavioral Economics
• Cognitive Psychology
• Neuroscience

Background:

• Human delay discounting research often lacks real waiting periods.
• Waiting can be perceived as aversive, influencing decision-making.
• Existing models may not fully capture the impact of immediate vs. deferred waiting.

Purpose of the Study:

• To introduce and validate a novel delay discounting paradigm incorporating actual waiting.
• To investigate how real waiting influences delay discounting behavior and subjective time perception.
• To explore the magnitude effect and gain-loss asymmetry within this new paradigm.

Main Methods:

• Developed a novel delay discounting task with immediate waiting periods.
• Employed hierarchical Bayesian modeling to analyze discounting and time perception mechanisms.
• Conducted two experiments comparing real waiting vs. deferred waiting conditions.

Main Results:

• The real-time waiting task led to significantly greater discounting.
• Nonlinear (convex) time perception was observed during the online waiting task.
• Discounting parameters correlated with preference reversals regarding waiting.

Conclusions:

• Subjective time perception is crucial in intertemporal choices, alongside discounting tendencies.
• Novel paradigms with actual waiting are essential for understanding delay discounting.
• Findings challenge traditional models by highlighting the impact of immediate aversive waiting.
