Dissociated active and passive tactile shape recognition: a case study of pure tactile apraxia.
Disorders of tactile object recognition (TOR) may result from primary motor or sensory deficits or higher cognitive impairment of tactile shape representations or semantic memory. Studies with healthy participants suggest the existence of exploratory motor procedures directly linked to the extraction of specific properties of objects. A pure deficit of these procedures without concomitant gnost...
متن کاملTactile spatial resolution in blind braille readers.
OBJECTIVE To determine if blind people have heightened tactile spatial acuity. BACKGROUND Recently, studies using magnetic source imaging and somatosensory evoked potentials have shown that the cortical representation of the reading fingers of blind Braille readers is expanded compared to that of fingers of sighted subjects. Furthermore, the visual cortex is activated during certain tactile t...
متن کاملBlind Braille readers mislocate tactile stimuli.
In a previous experiment, we observed that blind Braille readers produce errors when asked to identify on which finger of one hand a light tactile stimulus had occurred. With the present study, we aimed to specify the characteristics of this perceptual error in blind and sighted participants. The experiment confirmed that blind Braille readers mislocalised tactile stimuli more often than sighte...
متن کاملActive and passive scene recognition across views.
Recent evidence suggests that scene recognition across views is impaired when an array of objects rotates relative to a stationary observer, but not when the observer moves relative to a stationary display [Simons, D.J., Wang, R.F., 1998. Perceiving real-world viewpoint changes. Psychological Science 9, 315-320]. The experiments in this report examine whether the relatively poorer performance b...
متن کاملFinger Braille Recognition System
The Ministry of Health, Labour and Welfare of Japan estimates that there are nearly 22,000 deafblind people in Japan (2006). Communication is one of their largest barriers to independent living and participation. Deafblind people use many different communication media, depending on the age of onset of deafness and blindness and the available resources. “Yubi-Tenji” (Finger Braille) is one of th...
