Cross-modal plasticity in the deaf enhances processing of masked stimuli in the visual modality

Abstract Compensatory changes as a result of auditory deprivation in the deaf lead to higher visual processing skills. In two experiments, we explored if such brain plasticity in the deaf modulates processing of masked stimuli in the visual modality. Deaf and normal-hearing participants responded to...
