Novel cooperation task identifies social coordination strategies and deficits in Fragile X Syndrome.

This research aims to explore mechanisms of cooperative behavior in rats and how they are affected in a model of Fragile X Syndrome.
Developed a cooperation task for rat pairs to visit reward wells on spatial mazes under different reward conditions.
Utilized dyads of littermate wild-type and Fmr1 knockout rats to assess their cooperation strategies.
Compared the efficiency and flexibility of their cooperative behaviors, focusing on turn-taking and predictive strategies.
Wild-type rats achieved significantly greater cooperation success than Fmr1 knockout rats in the task.
Both groups used a simple follower-tracking-leader strategy, but wild-type rats also employed efficient predictive strategies for faster cooperation.
Fmr1 rats showed selective disruption in social reciprocity and an inability to effectively predict and synchronize with partner actions.

Shukla et al. (2026) studied this question.
