Eye-tracking and clinical data reveal a student’s emergent attentional anchor as their solution to a problem of coordinating bimanual orthogonal movements. In this activity variant, the left hand moves up/down the y-axis while the right hand moves right/left along the x-axis. The screen will be green only when the left and right hands’ respective distances from the origin (bottom-left corner) relate according to the target ratio (here, 1:2). a A student uses an emergent attentional anchor to guide proportional bimanual coordination: they are focusing on an imaginary diagonal line between the tips of their left-hand and right-hand index fingers, keeping this line at a constant angle to the x-axis while moving the line to the right. b The same student from a is explaining their strategy to the experimenter. They gesture an imaginary diagonal line running down from a point on the y-axis to a point on the x-axis
