Abstract
Three independent studies are reported in which periods of “relaxation” (A) and presumed Stressors (B) were given to female students in an ABA design. The “Stressors” were: (1) obligatory time-wasting activity; (2) a mental “IQ” test; and (3) delivering a speech. Saliva was collected immediately after “relaxation” and “stress” periods. “Stress” and “arousal” state were retrospectively assessed in experiments (1) and (2) by subject self-rating and in experiment 1 also by trained observers for the periods A and B. The molar [K+/Na+] ratio was determined for each saliva sample. The prediction that [K+/Na+] would increase with stress induction was supported by statistically significant results with Stressors l and 2 (p < 0.01), but speech delivery (3) resulted in a significant rise of [K+/Na+] after the Stressor period. Correlations between [K+/Na+] and “stress” and “arousal” ratings also substantiated the prediction.
