...SCRs are both heightened by administration of dextroamphetamine (Zahn, Rapoport, & Thompson, 1981), caffeine (Zahn & Rapoport, 1987), and threatening instructions (Bohlin, 1976)....

...As expected on the basis of previous studies involving threat (Bohlin, 1976), SCL in CXT and CXT increased over time, reflecting increased tonic arousal, and SCL habituation was reduced as suggested by a weak qua- dratic trend of run (F(1,11) 4.1; p 0.068)....

...Thus, behavioral manipulations which increase arousal (e.g., threat of shock or instructions to perform a task) also significantly increase the rate of NS-SCRs (Katkin 1975; Bohlin 1976)....

...However, this value can be substantially increased if the stimulus is made task-significant (Ray, Piroch, and Kimmel 1977) or intense (Turpin and Siddle 1979) or if the subject's tonic arousal level is increased (Bohlin 1976)....

...However, this value can be substantially increased if the stimulus is made task-significant (Ray, Piroch, and Kimmel 1977) or intense (Turpin and Siddle 1979) or if the subject's tonic arousal level is increased (Bohlin 1976). This measure of habituation exhibits moderately high test-retest reliabilities in normal subjects, generally between .50 and 60 for mild stimuli and between .60 and .70 for strong stimuli for periods ranging from 1 week up to 5 months (Crider and Lunn 1971; Bull and Gale 1973; Crider and Augenbraum 1975; Siddle and Heron 1976). There is a small subgroup of subjects in the normal population, usually between 5 and 10 percent, which at any one time fails to give SCR-ORs to innocuous environmental stimuli. Simons et al. (1983) tested 250 college undergraduates and selected 24 SCR-OR nonresponders and 24 SCR-OR responders for further study....

...…usefulness as an index of sympathetic arousal includes the observations that SCL is significantly increased by pharmacological manipulations (e.g., administration of dextroamphetamine ; Zahn, Rapoport, and Thompson 1981) and behavioral manipulations (e.g., threat of electric shock; Bohlin 1976)....
