Information processing in goal-directed movements.
Sensory-motor interaction in pointing at visual targets without sight of the pointing arm was evaluated in human subjects, using information theory. Equations were derived to determine transformation in channels with amplitude-continuous output signals, which overcome the problems involved in dividing the output into discrete bins. The equations were applied to calculate transinformation in our pointing experiment, and to predict transinformation under a variety of different experimental conditions. The results apply also to other systems that can be regarded as channels with similar properties.
