Auditory-tactile speech perception in congenitally blind and sighted adults.
The present study investigated whether manual tactile information from a speaker's face modulates the intelligibility of speech when audio-tactile perception is compared with audio-only perception. Since more elaborated auditory and tactile skills have been reported in the blind, two groups of congenitally blind and sighted adults were compared. Participants performed a forced-choice syllable d...
متن کاملFrom Perception to Metacognition: Auditory and Olfactory Functions in Early Blind, Late Blind, and Sighted Individuals
Although evidence is mixed, studies have shown that blind individuals perform better than sighted at specific auditory, tactile, and chemosensory tasks. However, few studies have assessed blind and sighted individuals across different sensory modalities in the same study. We tested early blind (n = 15), late blind (n = 15), and sighted (n = 30) participants with analogous olfactory and auditory...
متن کاملBlind and Sighted Individuals
sapopulation ages, elderly people increasingly fall and injure themselves. Such falls make them hesitant to move actively and thus severely decrease their independence and quality of life. Preventing falls is therefore critical in maintaining the wellness of elderly people. In physiotherapy, a tracking task for an ankle-joint exercise can be used to facilitate motor learning of the ankle. For s...
متن کاملAnticipatory spatial representation of 3D regions explored by sighted observers and a deaf-and-blind-observer.
Viewers who study photographs of scenes tend to remember having seen beyond the boundaries of the view [boundary extension; J. Exp. Psychol. Learn. Mem. Cogn. 15 (1989) 179]. Is this a fundamental aspect of scene representation? Forty undergraduates explored bounded regions of six common (3D) scenes, visually or haptically (while blindfolded) and then the delimiting borders were removed. Minute...
متن کاملHaptic orientation perception benefits from visual experience: evidence from early-blind, late-blind, and sighted people.
Early-blind, late-blind, and blindfolded sighted participants were presented with two haptic allocentric spatial tasks: a parallel-setting task, in an immediate and a 10-sec delay condition, and a task in which the orientation of a single bar was judged verbally. With respect to deviation size, the data suggest that mental visual processing filled a beneficial role in both tasks. In the paralle...
