Space-time mapping relationships in sensorimotor communication during asymmetric joint action

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Social Neuroscience

Background:

• Sensorimotor communication is crucial for joint actions and social interactions.
• Understanding the cognitive underpinnings of sensorimotor communication remains a challenge.

Purpose of the Study:

• To investigate the cognitive mechanisms of sensorimotor communication in individuals.
• To examine how cooperative intention influences action performance in distance and orientation tasks.

Main Methods:

• A repeated-measures design with 65 participants was employed.
• Experimental conditions included cooperative intention (Coop, No-coop) and task characteristic (distance, orientation).
• Action performance was measured across four target types (T1-T4).

Main Results:

• Cooperative intention led to increased target key dwell time, motion time, and maximum motion height.
• In distance tasks, cooperative intention showed increasing trends in dwell time and variability with target distance.
• In orientation tasks, cooperative intention demonstrated increasing trends in dwell time and variability, mapping actions to spatial directions.

Conclusions:

• Cooperative intention is vital for effective sensorimotor communication.
• Participants utilized sensorimotor experience to create 'near-small, far-large' mappings in distance tasks.
• In orientation tasks, sensorimotor experience and verbal metaphors informed action mappings for communication.
