Motion-guided attention promotes adaptive communications during social navigation.

Area of Science:

• Behavioral Ecology
• Computational Neuroscience
• Collective Behavior

Background:

• Cooperative decision-making in animals relies on social cues for coordination, especially in uncertain environments.
• Information processing challenges arise in groups, potentially leading to confusion and increased individual risk.
• Mechanisms for rapid and accurate processing of competing social cues in animal groups remain poorly understood.

Purpose of the Study:

• To model how motion-guided attention influences information exchange during social navigation in animal groups.
• To compare the effectiveness of motion-guided attention with attention limited to a fixed number of nearest neighbors for robust social coordination.
• To investigate how selective attention to motion cues impacts group decision-making dynamics.

Main Methods:

• Agent-based modeling to simulate social navigation and information exchange.
• Comparison of motion-guided attention models against nearest-neighbor attention models.
• Analysis of how varying motion thresholds and social contexts affect group decisions.

Main Results:

• Numerically limited attention (n-nearest neighbors) does not ensure robust social navigation across diverse ecological contexts.
• Motion-guided attention allows individuals to act as information hubs instantly when alerted, without altering neighbor attention levels.
• Individuals can overcome speed-accuracy trade-offs by adjusting motion detection thresholds, enabling groups to modulate social information.
• The proportion of individuals needed to influence group direction varies significantly with the social context.

Conclusions:

• Motion-guided attention is a fundamental and efficient mechanism for collaborative decision-making in social navigation.
• Selective attention to motion cues provides flexibility in information processing and group coordination.
• This mechanism allows for dynamic adjustment of influence within a group based on environmental and social factors.
