A Cognitive Neuroscience Study in Multi-Agent Box-Pushing Adversarial Games

The provided analysis highlights the significant impact of synaptic plasticity (R-STDP) on role reorganization and the emergence of altruistic behaviors in a simulated environment. Here are key points summarized:

Role Reorganization

Fixed Weights:

• Right team Robot1 pushes 21 times, Robot0 pushes 0.
• This indicates a rigid division of labor where one robot is specialized for pushing while the other does not engage.

R-STDP:

• Right team Robot0 pushes 14 times, Robot1 pushes 0.
• There's a complete reversal in roles due to online learning, suggesting flexibility and adaptability driven by synaptic plasticity.

Emergence of Altruistic Rescue Behavior

Fixed Weights:

• 10 rescues, but only 9 are counter-kills (self-defense).
• No genuine altruistic rescue behavior is observed as the rescuer's actions are primarily self-serving.

R-STDP:

• 11 rescues, with 6 being approach rescues (55%).
• A significant qualitative shift towards genuine altruism where robots actively move to help injured teammates, driven by learning that such behaviors benefit team score.
