Facial flushing was studied in 38 young women who
scored high or low on trait anger. To induce anger in the
subjects, their task was to solve a difficult puzzle, with
or without harassment from a female research assistant.
Facial blood flow increased in response to provocation,
together with increases in cardiovascular and electrodermal
activity. Flushing was associated with large increases
in electrodermal activity and small increases in diastolic
blood pressure. Subjects high in trait anger reported most
anger and embarrassment, but physiological activity did
not differ from subjects with low trait anger. The findings
suggest that sympathetically mediated vasodilatation in
facial blood vessels competes with cutaneous vasoconstriction
during anger. Unpleasant sensations of facial warmth might
heighten aversive emotional experiences, but dilatation
of facial blood vessels could also act as a type of “safety
valve” by opposing increases in blood pressure. An
angry predisposition may influence the subjective experience
of anger in women, but does not seem to have a major influence
on physiological reactivity to mild provocation.
