Visual perception of external stimuli can be influenced by the internal state of the perceiver. This study investigates how threat anticipation modulates conscious visual perception using the breaking Continuous Flash Suppression (b-CFS) paradigm, a visual masking method that delays the access of stimuli to conscious awareness. In a within-subjects design, 40 participants undergo a threat-of-shock manipulation, inducing changes in internal state. Neutral faces are presented under b-CFS in both upright (ecologically meaningful) and inverted (not meaningful) orientation to determine whether threat differentially affects processing of higher-order stimulus properties. We assess how threat influences stimuli’s access to awareness via Signal Detection Theory. Importantly, we separate detection (“Did you see something?”) from discrimination (“Was the stimulus upright or inverted?”) to differentiate responses often conflated in the b-CFS literature. Based on prior research, we hypothesize that threat will enhance perceptual sensitivity (d′) and reduce reaction times. We further examine how face orientation modulates this effect, and whether detection and discrimination are differentially influenced by emotional state. Data collection is ongoing, and findings will be reported at the conference. This study aims to provide novel insights into the interplay between perceiver states and conscious visual perception, and it contributes a refined methodological approach to assessing perceptual awareness during b-CFS.
