[Relationship between recognition asymmetry and the interval between the stimuli of a dichoptic complex]

Recognition of optic stimuli (contour drawings, words and word combinations) was studied in conditions of binocular, monocular and dichoptic presentation. The interval between stimuli of the dichoptic complex (ISI) was: 0, 10, 20, 50, 100, 200, 400, 600, and 1000 ms. In all the cases "the effect of the right eye" was revealed. The mean values of the asymmetry index (A) are: high probabilistic monocular dichoptic presentation--45%. With a longer ISI, the percentage of correct recognitions of the second stimulus presented to the left eye, increases, while the A parameter decreases. This dependence is less pronounced in the recognition of the first terms of the stimuli pair. Dependence between the recognition level of the first and second stimuli, presented to the right eye and the ISI, is monotonous. The following A values for the three kinds of stimuli have been obtained: drawings--37%, word combinations--38% and words 59%. The results are discussed in the aspects of functional asymmetry, psychologic refractoriness and attention.
