[Neuropsychological methods of examination of age-specific performance parameters (author's transl)].
200 test persons were subjected to a double-blind experiment involving a medication of K. H. 3 (Schwarzhaupt). The measurement procedures involved 9 apparatus dealing with psychophysiological measurement level methods and led to the following outcomes: 1) Increase of the psychomotor tempo of the dominant hand after 5 month application of K. H. 3 (motor performance series). -2) Reduction of reaction errors determined by a vigilance measurement instrument after 5 month treatment with K. H. 3 (evidenced by an increase in monotony resistance and continous attention). -3) Improvement of multiple-choice reactions (simultaneous reaction capacity) to optic, acoustic and orientation-linked stimuli (fewer false and delayed reactions). -4) Increase of visual attentiveness and visual short time memory after 5 month medication of K. H. 3 measured by the Cognitron concentration measurement device). No statistically significant differences of the investigated performance parameters were found between K. H. 3 and placebo groups after 3 month application of K. H. 3. The result of the present study involving measurements at the psychophysiological measurement level are compared with data of a previous study.
