Blindsight refers to the ability to make accurate visual discriminations without conscious awareness of the stimuli. In this study, we present new evidence from naturalistic observations of a patient with bilateral damage to the striate cortex, who surprisingly demonstrated the ability to detect colored objects, particularly red ones. Despite the slow and effortful process, the patient reported...

We examined whether semantic processing occurs without awareness using continuous flash suppression (CFS). In two priming tasks, participants were required to judge whether a target was a word or a non-word, and to report whether the masked prime was visible. Experiment 1 manipulated the lexical congruency between the prime-target pairs and Experiment 2 manipulated their semantic relatedness....
