EFFECT OF COMPLEX MENTAL-VISUAL STRAIN ON VISUAL SENSORY SYSTEM AND PSYCHOMOTOR PARAMETERS
Complex visual and mental strain (sixty minutes study of learning presentation) induces mental fatigue of students. Significant decreasing of information processing rate was revealed in Anfimova test, psychomotor mobility reducing was observed in finger tapping test. Complex visual and mental strain also induced the visual sensory system parameters. Achromatic and chromatic vision fields were changed, visual acuity was reduced. Questioning of the students showed that the sixty minutes visual strain induced the signs of subjective visual fatigue and ocular discomfort - asthenopia.
