Arm Position Matching task data

<strong>Dataset Description</strong><p>
This repository processes proprioception data from four arm position matching (APM) studies. In the APM task, participants move their dominant arm to a target position and then reproduce that position with the other arm. Kinematic data (hand positions, target positions) were recorded with a KINARM endpoint robot.

<strong>Data</strong><p>
Each participant/hand yields one CSV file with the following columns: trial_number, frame, time, absolute_time, Right_HandX, Right_HandY, Left_HandX, Left_HandY, TargetX, TargetY
<p>
Positions are in meters. absolute_time is continuous across trials (seconds since session start).
