FIELD: physics.SUBSTANCE: method employs a device in the form of a stand with two telescopic posts with induction sensors. A metal sphere moves on a channel at an angle of 5° and when the sphere passes the first induction sensor, an electrical signal is generated which triggers an electric stopwatch, and when the sphere passes the second induction sensor, the stopwatch stops. The second induction sensor is turned off and the test subject stops the stopwatch at the moment of seeing the sphere cross the finishing line by pressing a button. The reading of the stopwatch is the visual-motor reaction time. From 50 to 100 tests are carried out, which include recording all attempts by a test subject, including premature pressing of the button, constructing a personal bar chart for each test subject and selecting a standard criterion for evaluating and comparing the visual-motor reaction.EFFECT: method increases accuracy and objectivity of evaluating visual-motor reaction to movement of an object in space.4 dwg, 1 ex |
