The role of motor programming, command, and standard in the central control of skilled movement.
Central control of skilled movement was investigated in a tapping task under total reduction of peripheral feedback with a nerve compression block. Practice conditions including no practice, tapping with normal feedback with either hand, or writing were manipulated prior to application of the block and were given in random order over 8 experimental trials to 48 Ss, followed by 6 further training trials. 2 control groups (12 and 11 Ss) were trained with constant practice conditions. Learning was dependent on constant practice conditions throughout the trial series. Findings were discussed in terms of central closed-loop systems, i.e., motor programming, or standards-programming units. The utilization of these units involves different strategies. Ss were classified as α or β according to their ability to utilize these units.
