Hitting moving targets: Co-operative ‘when’ and ‘where’
In this study we present evidence that two independent regulatory mechanisms, governing when and where the target will be hit, function together to allow us to hit moving targets. In the first part of the paper we show that subjects anticipate that the targets will have moved by the time they reach them, but that they do not anticipate how far they will have moved. The resulting systematic erro...
متن کاملIndependent control of acceleration and direction of the hand when hitting moving targets.
Human subjects were asked to hit moving targets as quickly as they could. Nevertheless the speed with which the subjects moved toward identical stimuli differed between trials. We examined whether the subjects compensated for a lower initial acceleration by aiming further ahead of the target. We found that the initial acceleration of the hand and its initial direction were hardly correlated. Th...
متن کاملHitting moving targets: a dissociation between the use of the target's speed and direction of motion.
Previous work has indicated that people do not use their judgment of a target's speed to determine where to hit it. Instead, they use their judgment of the target's changing position and an expected speed (based on the speed of previous targets). In the present study we investigate whether people also ignore the target's apparent direction of motion, and use the target's changing position and a...
متن کاملVerbalizations Affect Visuomotor Control in Hitting Objects to Distant Targets
There is a long-standing proposal for the existence of two neuroanatomically and functionally separate visual systems; one supported by the dorsal pathway to control action and the second supported by the ventral pathway to handle explicit perceptual judgments. The dorsal pathway requires fast access to egocentric information, while the ventral pathway primarily requires allocentric information...
