[Effects of weightlessness on sensorimotor interaction in the operator'work: proprioceptive feedbacks]. / Vliianie nevesomosti na sensomotornoe vzaimodeistvie pri operatorskoi deiatelnosti:propriotseptivnye obratnye sviazi.

During the 2nd Soviet-French Space Flight an operator ability to reproduce from memory the different positions of handles was studied. It is indicated that the temporal parameters of movement and the number of distinguishable positions of handle were not significantly influenced by microgravity effect. However, the accuracy of setting the handle to a given position at the beginning of the flight was significantly lower with an error towards a decrease of handle deflection angle. It is assumed that the cause of this is the proprioceptive feedbacks changes.
