Action-effect anticipation and temporal adaptation in social interactions

Area of Science:

• Cognitive science and social psychology
• Human-computer interaction
• Neuroscience of social interaction

Background:

• Social interactions involve complex action control mechanisms.
• Anticipation and adaptation are known to influence individual action execution.
• The interplay of anticipation and adaptation in social contexts is under-explored.

Purpose of the Study:

• To investigate how anticipation and adaptation contribute to action initiation speed in dyadic interactions.
• To determine the independent and parallel effects of anticipation and adaptation on social action control.

Main Methods:

• Four experiments were conducted involving dyadic interactions.
• Experiment 1 manipulated response compatibility to examine the interplay of anticipation and adaptation.
• Experiments 2-4 used virtual partners to isolate the effects of each mechanism on action execution.

Main Results:

• Agents initiated actions faster when anticipating a compatible partner response.
• Agents also initiated actions faster when their partner responded more quickly on the preceding trial (adaptation).
• Anticipation and adaptation demonstrated parallel but independent effects on action execution.

Conclusions:

• Both anticipation and adaptation independently and concurrently influence action control in social interactions.
• Findings provide insights into the mechanisms underlying social action coordination.
• The study advances models of action control within social contexts.
