Corroborative evidence for difference in arousability between internal and external scorers on Rotter's I-E Locus of Control Scale.

Here we report data about the answers on the Hopkins Symptom Check List for 68 students who participated in an experiment. About random half of the subjects were submitted to sham physiological measurements, the others not. Scores on Rotter's I-E Locus of Control Scale were also available. Analysis indicated that sham physiological measurement treatment is associated with more health complaints and more among external scorers on the Locus of Control Scale. These findings are interpreted as the result of increased arousal by the treatment and higher arousability among external scorers.
