摘要:

ABSTRACTSpontaneous heart rate changes and spontaneous galvanic skin response (GSR) fluctuations were compared with motor performance on a task said to measure motor impulsivity in two identical experiments. With the use of a total of 64 male college students as subjects, the conclusion drawn from the experiment was that neither of the physiological measures related significantly to impulsive performance. This was true for both a complex motor task and for simple reaction time performance. It is argued that if there is a relationship between spontaneous autonomic activity and motor impulsivity as has been previously reported, the conditions under which this may be demonstrated must be quite specific. The present findings are interpreted as requiring limitations on the generalizability of the relationship previously reported. Heart rate, GSR, Impulsivity, Reaction time. (R. F. Docter)

摘要:

ABSTRACTIn three independent studies using 105 subjects, regression analysis was used to determine which autonomic variables are most affected by the “law of initial value” and whether the “law” always acts in the same way, i.e. are large responses always associated with low prestimulus levels of activity and conversely. For GSR, heart rate, respiration rate, and skin temperature it was found that the slope of the regression of stimulus level on prestimulus level (Byx) distinguishes these four ANS variables. The conclusion is that the LIV operates as one would predict for heart rate and respiration rate responses, with values ofByxless than one; but that the law does not operate for skin (finger) temperature responses, sinceByxis consistently very close to one. For GSR responses expressed in terms of conductance, the converse of the LIV seems to hold, withByxconsistently greater than one. Law of initial value (LIV), Autonomic nervous syste
