The Ponzo illusion with auditory substitution of vision in sighted and early-blind subjects.
We tested the effects of using a prosthesis for substitution of vision with audition (PSVA) on sensitivity to the Ponzo illusion. The effects of visual experience on the susceptibility to this illusion were also assessed. In one experiment, both early-blind and blindfolded sighted volunteers used the PSVA to explore several variants of the Ponzo illusion as well as control stimuli. No effects o...
متن کاملFunctional cerebral reorganization for auditory spatial processing and auditory substitution of vision in early blind subjects.
Early blind (EB) individuals can recognize bidimensional shapes using a prosthesis substituting vision with audition (PSVA) and activate right dorsal extrastriate visual cortex during the execution of this task. The present study used repetitive transcranial magnetic stimulation (rTMS) to further examine the functional role of this structure in the successful use of the PSVA. Moreover, we inves...
متن کاملBasis of the horizontal-vertical illusion.
Three experiments were designed to determine the basis of the horizontalvertical (HV) illusion using an L figure. Experiment I showed that there were no differences in the size of the effect in darkness, semidarkness, and in the light, a result contrary to the visual field explanation. In Exp. II the figure was viewed in the dark with 5s upright and recumbent, and in Exp. Ill the L figure was o...
متن کاملHaptic Object Recognition is View-Independent in Early Blind but not Sighted People.
Object recognition, whether visual or haptic, is impaired in sighted people when objects are rotated between learning and test, relative to an unrotated condition, that is, recognition is view-dependent. Loss of vision early in life results in greater reliance on haptic perception for object identification compared with the sighted. Therefore, we hypothesized that early blind people may be more...
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...
