Abstract
The interaction of visual and proprioceptive afferentation were studied in the motor task for discrimination of weights of falling objects. The availability of visual information reduced the time of motor response; however, the degree of shortening depended on the type of this information. The decrease in the response time was significantly greater when the subject saw the beginning of the real falling of object instead of having only visual information about the beginning of the fall. Thus, a subject solves the motor task for discrimination of weights of falling objects more efficiently when he sees the real beginning of the fall, rather than in the case when the subject receives only a visual signal at the moment when an electromagnet releases the object. This may be due to the fact that seeing the initial part of a real trajectory instead of an abstract signal about the beginning of the fall allows the subject to better predict the moment of the impact.
