We examined salivary reactivity in Il women with simple phobia of spid
ers and 11 controls in response to a spider and a neutral cue. No diff
erences in salivary reactivity were observed across diagnosis or condi
tions. Clear reactivity in heart rate, systolic blood pressure, and su
bjective units of distress were observed. Salivary reactivity was unre
lated to any other measure of reactivity, These results suggest that a
decrease in salivation is not a universal response to acute anxiety.
