Reaction time in the unconstrained tasks.A, Mean normalized RT and mean achieved direction for 10 bins of achieved direction in the unconstrained rotation task.Thinner lines here and in D illustrate that regression results from the constrained tasks. B, Mean normalized achieved movement distance and mean achieved direction for 10 bins of achieved direction in the unconstrained rotation task.C, Mean normalized RT and achieved movement distance for 10 bins of achieved movement distance in the unconstrained rotation task. D, Mean normalized RT and mean achieved distance for 10 bins of achieved distance in the unconstrained extension task.E, Comparison of the RT slopes for visual motor extension obtained from the constrained and unconstrained tasks.
