Fig 2. A schematic representation of the presentation timing.

(A) Functional localizer. Participants were presented with baseline, auditory (beep), dynamic visual (checkerboard), and naturalistic audiovisual stimuli in a block design. Each block lasted for 12s. (B) Main experiment. Participants were presented with naturalistic audiovisual stimuli selected from the four quadrants of the affective space: high arousal negative valence (HN), low arousal negative valence (LN), low arousal positive valence (LP), and high arousal positive valence (HP). Each audiovisual clip was presented for 5s, followed by 7s fixation.
