How multilevel competition drives cooperation in stigmergic systems

The paper investigates how competition within and between groups affects cooperation in stigmergic systems using the Stigmer Game with human participants under different payment rules.

Closed-loop robotic interactions reveal dynamic social filtering in schooling fish

The paper uses a robotic fish to test interaction rules in schooling fish, showing that hydrodynamic interactions are critical for collective behavior.

Tracing information propagation in fish schools with a conditioned escape response

This study investigates how escape information spreads in fish schools by conditioning some individuals and observing collective behavior.

Closed-loop real-virtual interactions validate 3D model of social coordination in fish

The paper develops a 3D model of social coordination in fish using real behavior data and validates it through a closed-loop virtual reality system.

Swimming speed of schooling fish controls social interaction strength in open-loop immersive virtual reality

This study shows that swimming speed affects social interaction strength in fish by altering attraction, alignment, and repulsion behaviors in a virtual reality setup.

Group size and social interactions' strength determine collective response to perturbation in a model of burst-and-coast swimming fish

The paper uses a computational model to show that group size and social interaction strength affect how fish groups respond to perturbations, with larger groups being more sensitive to disturbances.

Decoding social integration in schooling fish using closed-loop real-virtual interactions

The paper uses a closed-loop virtual-reality system to study how schooling fish integrate social information, finding that fish primarily respond to the most influential neighbor.

An open-source closed-loop Virtual Reality system to investigate social interactions and collective behavior in fish

Real rummy-nose tetras follow a projected, anamorphically rendered virtual conspecific in a low-cost open-source 3D-tracked VR bowl, largely matching its speed and depth; a moving sphere elicits weak following.

Experimental evidence of stress-induced critical state in schooling fish

This study shows that schooling fish adjust their social interactions under stress to reach a critical state, enhancing adaptability, with group size influencing the need for external stressors.

Collective phases and long-term dynamics in a fish school model with burst-and-coast swimming

This paper introduces a fish school model with burst-and-coast swimming that replicates collective phases like schooling and swarming, but cohesion diminishes over time except in swarming.
