Fig. 3. Group comparison of patients with erythrophobia and normal control subjects in resting and mental stress conditions. Significant ANOVA effects for total power (p < .01), midfrequency (p < .05), and high-frequency (p < .001), top, middle, and bottom, respectively. Units are arbitrary ln power units (ln ms²), solid lines represent patients with erythrophobia (N = 40), dotted lines denote control patients (N = 20).
