Frequency effects in decision-making involving loss minimization.

Area of Science:

• Cognitive Psychology
• Neuroeconomics
• Decision Sciences

Background:

• Frequency effects in decision-making show preference for high-frequency options, even if less rewarding.
• The Decay reinforcement-learning (RL) model predicts this, assuming better memory for frequent outcomes.
• Research has primarily focused on gains, leaving loss-minimization scenarios under-explored.

Purpose of the Study:

• To test the Decay model's prediction of a reversed frequency effect in loss-minimization.
• To investigate how frequency influences choices when the goal is to minimize losses.
• To develop and evaluate alternative models for decision-making under losses.

Main Methods:

• Three experiments were conducted involving loss-minimization tasks.
• Participants made choices in scenarios designed to minimize losses (points or hypothetical expenditures).
• Data was analyzed to assess the fit of the Decay model and novel proposed models (PVPE-Decay, Delta-Uncertainty).

Main Results:

• The Decay model poorly predicted behavior in loss-minimization scenarios.
• A modest frequency effect was observed in a shopping context (Experiment 2).
• Frequency effects were attenuated but not reversed in point-minimization tasks (Experiments 1 & 3).

Conclusions:

• The Decay model is inadequate for explaining frequency effects in loss-minimization.
• Novel models, PVPE-Decay and Delta-Uncertainty, offer better explanations for observed effects.
• Context and relative value processing are crucial for understanding decision-making under losses.
