Perceptuo-motor compatibility in pursuit tracking of two-dimensional movements

Abstract In a previous article, we reported an investigation of visuomanual pursuit tracking of unpredictable two-dimensional targets. This article extends the study to the tracking of predictable stimuli. In both investigations, the target trajectory was elliptical.The experimental factors were the orientation of the major axis of the ellipses, the period of the movement and the law of motion (natural vs. transformed). The main results of the study are as follows: (a) Satisfactory performance is achieved only in the natural condition. Pursuit movements obey the same constraints observed in spontaneous movements. (b) Predictability affects significantly the average delay between target and pursuit.(c) Each component of the pursuit movements depends on both components of the target. (d) The simple model developed previously to describe performance with unpredictable targets can be generalized to cover the present case as well.
