The electro encephalogram as a research tool in human behavior genetics psychological examinations in healthy males with various inherited electro encephalogram variants part 2 results


, : The electro encephalogram as a research tool in human behavior genetics psychological examinations in healthy males with various inherited electro encephalogram variants part 2 results. Human Genetics 47(1): 47-80

The results of psychological examinations on 298 adult male probands with various inherited EEG variants are described. The low-voltage (N) group scored high in intelligence tests, especially in spatial orientation. Personality scores revealed this group as normal, extraverted group-dependent and not very energetic. The borderline low-voltage (NG) group showed slight weakness in abstract thinking, short-time memory and motor skills. They had a relatively strong tendency to have neurotic complaints and poor reaction time and motor skills. The occipital fast .alpha.-variants (BO) group performed very well in tests of abstract thinking and motor skills. The monotonous .alpha. (R) group showed average performance in most intelligence scores but above-average in short-time memory and in precision under stress conditions. Personality scores indicated high spontaneous activity and tough-mindedness. The BG (fronto-precentral .beta.-group) category showed very low MMPI [Minnesota Multiphasic Personality Inventory] scores, indicating little neurotic tendency. Intelligence could be above average. The diffuse .beta. (BD) groups scored low in intelligence tests, especially in spatial orientation, and had a high error rate in tests measuring concentration and precision. Most differences were relatively small and the whole range of test scores was found in all EEG groups.
