[Task specificity and reproducibility of the psychophysiologic reaction pattern].
This paper presents results from investigations of physiological activation processes concerning two subjects. Firstly: Different tasks cause different reactions of the activation variables. In our experiment the heart rate raised stronger in the mental arithmetic task than in the trakking task. Conversely, blood pressure and respiratory frequency showed higher values in the tracking task. Secondly: By analyzing the stabilities for repeated investigations we obtained the following results: a) The reliability of the physiological strain variables is higher than that of the difference values. b) Habitual values are predicted best by the second investigation. c) If the experiment is often repeated, one can determine intraindividual correlations between activation variables for every single person.
