In the present study, we examined how subjectslocate spatial positions and code them in short-termmemory. In the first experiment, blindfolded subjects wereasked to perform movements in the near or farperipersonal space (criterion movement, CM). Then,subjects had to reach the end-point of CM (reproductionmovement, RM). Movements could be performed eitherslowly or rapidly. Also, CM and RM could be performedwith the same (congruent conditions) or different velocity(incongruent conditions). The results showed that performancewas accurate in the two congruent conditions.Conversely, in the incongruent conditions, subjects madeundershoot errors when the CM was fast and overshooterrors when it was slow. In the second experiment,blindfolded subjects also performed CM and RM incongruent or incongruent conditions. However, the CMand RM could start from the same or different position.We found again undershoot errors when the CM was fastand RM was slow and overshoot errors in the reversecondition. The results of both experiments suggest that theinformation about movement velocity contributes to thekinaesthetic coding in memory of a spatial location to bereached with arm movement.
