Diffusion model-based understanding of subliminal affective priming in continuous flash suppression

Abstract Affective states influence our decisions even when processed unconsciously. Continuous flash suppression (CFS) is a new variant of binocular rivalry that can be used to render the prime subliminal. Nonetheless, how prior information from emotional faces suppressed by CFS influences subseque...
