    Abstract

    Three experiments investigated whether emotional information influences perceptual dominance during binocular rivalry. In Experiment 1, rival emotional and neutral faces in the background were coupled with grating stimuli in the foreground. Results showed that gratings paired with emotional faces dominated over those paired with neutral faces. In Experiment 2, emotional and neutral faces were presented dichoptically, without being paired with other stimuli. Dominance of emotional faces was observed. Fusion and low-level image differences were ruled out by examining dominance periods of upright and inverted emotional and neutral faces presented as face-house pairs (Experiment 3). Here, face stimuli dominated over house stimuli only for upright face conditions. In addition, upright emotional faces were perceived for significantly longer durations than upright neutral faces. The results provide further support for the influence of emotional meaning on binocular rivalry.
