This podcast explores the concept of degrees of freedom in joint actions. It discusses a study on joint action learning and its relation to degrees of freedom. The results reveal improvements in performance and changes in freezing and complimentary ratios with practice. Analyzing an experiment, it shows that switching from joint to solo tasks increases freezing. The podcast emphasizes the influence of task constraints, practice, and experience on degrees of freedom in joint action learning.

Joint action involves the coordination of degrees of freedom across multiple individuals for a shared goal.
Prior experience and task constraints can influence the coordination of degrees of freedom in joint action tasks.
Deep dives
Learning joint action coordination
This podcast episode discusses how the coordination of degrees of freedom works when two individuals perform a joint action. The example of carrying a piano together is used to demonstrate how the movements of both individuals are interdependent. The podcast highlights that in joint action, the degrees of freedom are distributed across both individuals, leading to a coordinated system. It explores the development of joint coordination and the concept of synergies, where two degrees of freedom work together. The episode also discusses the role of practice and task constraints in shaping how individuals coordinate their movements.
The study of joint action learning
The podcast draws attention to the study of joint action learning and its significance in ecological psychology. It mentions that joint coordination has been extensively studied in various tasks, such as rocking chairs, to understand the interesting phenomena of interpersonal coordination. While acknowledging that the task used in the presented study may not be as realistic as others, the episode suggests that there are still valuable implications for understanding how individuals coordinate degrees of freedom in joint action tasks.
Experimental design and results
The podcast outlines the experimental design of the study, which involved participants performing joint and solo tasks with the goal of rolling a ball on a beam. Two training groups were created, one starting with the solo task and the other starting with the joint task. The podcast highlights that overall, participants performed better in the joint task compared to the solo task. The results also show that participants who initially practiced the solo task exhibited more evidence of freezing degrees of freedom, while those who started with the joint task showed more coordination and synergy in their movements. These findings support Bernstein's theory of freezing and freeing degrees of freedom and highlight the influence of prior experience on joint action coordination.
How do we coordinate degrees of freedom when learning a joint action, like carrying a piano, where two people are working together to achieve a goal? Do we see evidence of Bernstein’s freezing and freeing DF across the joint action system? Articles:Freezing and freeing of degrees of freedom in joint action learning More information:
