Motor invariants in action execution and perception

Francesco Torricelli et al.

Summary: The study suggests that building reliable predictive models of others' actions is essential for successful social interaction, and there is ample evidence that our movements follow kinematic invariants, which can be used to reduce uncertainty during social exchanges. Recognizing others' actions by anchoring socially-relevant perceptual decisions to these invariants provides a computational advantage for inferring conspecifics' goals and intentions.

Decoding social decisions from movement kinematics

Giacomo Turri et al.

Summary: This article investigates the kinematics of social decisions and discovers that movement can reveal important parameters in social decision-making, such as the fairness of a proposed offer and the decision to accept or reject it. This provides new insights into the relationship between decision-making and sensorimotor control.

Perceptual-motor styles

Pierre-Paul Vidal et al.

Summary: Even in a stereotyped task, sensorimotor behavior can be variable due to noise, redundancy, adaptability, learning or plasticity. The sources and significance of behavioral variability have attracted attention, but the idea that individual strategies play a role in this variability has been explored to a lesser extent. The concept of style in sensorimotor behavior has not been thoroughly studied, but it may contribute to personalized physiology and medicine.
