Time Synthesis in Organization of Sensorimotor Action

Time synthesis of sensorimotor action is reviewed as a process of a coherence setting action duration (expected duration), time sequence of required operations and significant changes in conditions. Aim: to experimentally set up the connection of time synthesis success and efficiency of realisation sensorimotor action in changeable conditions. Hypothesis: successful time synthesis of the setting duration and the temporal sequence of operations in the mental organisation of sensorimotor action in changing conditions is realised in accordance with the corresponding operational meaning and is allowed by anticipatory effects and an increase in the effectiveness of the action, materials and methods. An experimental study involved 152 male and female students. Participants of the investigation solved experimental tasks, implemented in a computer version, according to schemes of a simple visual-motor reaction and a choice reaction (separately and in combination), according to a scheme of sensorimotor action with a warning signal when the apperceptive scheme, setting duration and sequence of required operations were changed promptly. Results were reviewed in the aspect of disclosing the features of the subject's elimination of the uncertainty of the moment of achieving the goal in the future and the construction of a sequence of operations of sensorimotor actions in a connection with changes in external conditions, typical for the time deficit regime. The conditionality of the time synthesis of sensorimotor action by the actual operational meaning was established revealing that the successful temporal synthesis of sensorimotor action in changing conditions is associated with the fastest acceptance of an adequate apperceptive scheme, with effective anticipation of the moment of achieving the goal and the formation of a detailed setting duration of action, with the formation of a temporal sequence of required operations. Conclusions. The levels of success of the time synthesis of sensorimotor action in changing conditions are highlighted: "quite successful; moderately successful; unsuccessful."
