Discussion

Experiment demonstrates how resource-rationality affects implicature derivation in individuals, suggesting variance in social reasoning strategies.

MAIN FINDING: The model reveals how individuals vary in their ability to derive implicatures based on resource demands.
KEY EVIDENCE: The predictions of the model align closely with human performance across multi-trial signaling games.
APPROACH: Developed an ACT-R model to mechanistically simulate resource-rational strategies in pragmatic communication.
SIGNIFICANCE: This work advances understanding of social reasoning by linking resource-rationality with individual differences in engagement.

Duff et al. (2025) studied this question.
