Abstract
Functional neuroimaging studies have demonstrated that following deafness, auditory regions can respond to tactile stimuli. However, research to date has not conclusively demonstrated the behavioral correlates of these functional changes, with most studies showing normal-like tactile capabilities in the deaf. It has recently been suggested that more cognitive and complex tactile processes, such as music perception, could help to uncover superior tactile capabilities in the deaf. Indeed, following deafness music seems to be perceived through vibration, but the extent to which they can perceive musical features though the tactile modality remains undetermined. The goal of this study was to investigate tactile identification of musical emotion in the deaf. Participants had to rate melodies based on their emotional perception. Stimuli were presented through an haptic glove. Data suggest that deaf and control participants were comparable in the identification of three of the four emotions tested (sad, fear/threat, peacefulness). However and most importantly, for the simplest emotion (happiness), significant differences emerged between groups, suggesting an improved tactile identification of musical emotion in the deaf. Results support the hypothesis that brain plasticity following deafness can lead to improved complex tactile ability.
