In female participants the P3 peak appeared with a larger amplitude in response to chemosensory anxiety stimuli as compared to chemosensory control stimuli [Fig. 1a; Chemosensory Condition by Sex of Perceiver: F (1, 26) = 6.30, p = 0.019, f (Cohen's f) = 0.49, Power = 0.67; nested effects: Chemosensory Condition in female participants: F(1, 26) = 5.29, p = 0.030, f = 0.45, Power = 0.60].
