Group Foraging in Dynamic Environments

TL;DR

This study investigates how human groups forage in changing environments, examining reliance on social information versus individual assessment, and the impact of signals of others' success on group adaptation.

Contribution

It reveals that humans primarily rely on personal assessments over social cues, but social information influences behavior under certain conditions.

Findings

Humans mainly depend on individual assessments for foraging decisions.

Social signals influence group behavior when environmental cues are uncertain.

Participants adapt their foraging strategies based on environmental changes.

Abstract

Previous human foraging experiments have shown that human groups routinely undermatch environmental resources much like other animal species. In this experiment, we test whether humans also selectively rely on others as information sources when the environmental state is uncertain, and we also test whether overt signals of other foragers' success influences group matching behavior and group adaptation to a changing environment. The results show evidence of reliance on social information in specific conditions, but participants were primarily influenced by their individual assessments of food location rather than the success of other foragers.
