Methods
Experiment 1: social interactive task
Exp. 1 Methods Exp. 1 setup
Exp. 1 procedure
Exp. 1 data processing
-
Pair accuracy (ACC): percentage of trials in which both participants grasped their object in the correct location.
-
Grasping asynchrony (ms) (GraspAsynch): trial-by-trial absolute time interval between each participant’s grasp (hand contact) of the object [abs(participant1_grasp time − participant2_grasp time)].
-
Difference in reaction times (ms) (∆RT): trial-by-trial time interval between the release of the start button by the participant in the adaptive role and that of the participant in the instructed role (∆RT = adaptive RT − instructed RT).
-
Reaction time (ms) (RT): interval between auditory instruction delivery time and start button release time.
-
Movement duration (ms) (MD): interval between start button release time and grasp time.

-
Accuracy (ACC): percentage of trials in which participant grasped the object in the correct location.
-
Grasping asynchrony (ms) (GraspAsynch): trial-by-trial absolute time interval between participant’s grasp time and dot’s stop time [abs(participant_grasp time − dot_stop time)].
-
Reaction time (ms) (RT): interval between delivery time of auditory instructions and start button release time.
-
Movement duration (ms) (MD): interval between start button release time and grasp time.
