Sixty right-handed men, half classified as anxious without depressive symptoms,
the other half as nonanxious, participated in a tachistoscopic study of the influence of
anxiety without depression on hemispheric processing of Ekman and Friesen's (1976)
happy, angry, and neutral emotional faces. Results were counter to hypotheses, where
anxious subjects' reaction times to affective valences were slower than nonanxious
subjects. Additionally, anxious subjects failed to demonstrate a negative affective bias for
neutral stimuli. Results are discussed in terms of arousal theory, where anxious subjects
may be considered overaroused for the tachistoscopic task, thereby exhibiting slower
reaction times to affective stimuli. More specific neuropsychological hypotheses for
anxious individuals without depression versus nonanxious individuals in terms of
concurrent anterior dysfunction and posterior hyperarousal are discussed.
