METHODICAL AND METHODOLOGICAL PROBLEMS IN THE STUDY OF FUNCTIONAL BRAIN ASYMMETRY IN THE MODERN NEUROPSYCHOLOGY
Journal Title: Acta Neuropsychologica - Year 2013, Vol 11, Issue 3
Abstract
Diagnosis of interhemispheric asymmetry is an actual problem of modern neuropsychology. The researches show that tests meant for the diagnosis of one type of functional asymmetry often produce inconsistent results. We conducted a study to see how the results of different tests for the diagnosis of interhemispheric asymmetry are interconnected. The additional objective is developing a method, involving the calculation of tests weight.The study involved 116 subjects aged 16 to 23, including 37 men and 79 women. Test persons performed the following tests and analyses: A.P. Chuprikov questionnaire, ”Napoleon pose”, ”Applause”, ”Crossing of fingers”, ”Aiming” and ”Rozenbakh test”, dichotic listening to assess audioverbal asymmetry (20 subjects did not have it).Significant correlations were obtained only between self-report, Chuprikov questionnaire and ”Crossing of fingers” test, and between the results of Rozenbakh test and dichotic listening. The ”Crossing of fingers” test correlates with other manual tests negatively. This indicates that at crossing the fingers on the top there is a finger of nonleading hand.The concept of the independence of manual, audioverbal and visual fields is likely to be changed. The new method of evaluation of the integral index of asymmetry can be used to divide subjects into groups according to the degree of functional brain lateralization. The evolutionary approach using achievements of comparative physiology can be used as a methodological basis of human interhemispheric asymmetry studies.
