摘要:
The intercorrelations among fifteen common SRR variables were investigated on two samples of male subjects in a standard habituation paradigm. The first group (N = 212) was made up or 149 prisoners and 63 controls (mean age = 28 yrs) white the second group (N =84) were all twins (mean age-25 yrs). All subjects received 21 auditory stimuli at an ISI of 33 sec. Each stimulus was sinusoidal, at 1000 Hz, oil see duration and at 95 dB (re 20 N/cm[sup2]). The fifteen SRR measures taken from each subject included mean and change scores for basal conductance, response amplitude, spontaneous fluctuation frequency, number or responses. and onset, peak and half-recovery latencies. The variables were intercorrelated and factor analyzed. The .05 rejection region was adopted in all statistical tests. A fairly simple structure for the variables was demonstrated. The results emphasized the importance of a large general reactivity component in most of these variables. Within-subject correlations were calculated and found to be different from across- subject correlations. It is suggested that under constant stimulus conditions subjects display different but individually typical SCR shapes which reduce in size during habituation. [ABSTRACT FROM AUTHOR]
