Dissociating detection from localization of tactile stimuli.
In what they described as "a tactile analog of blindsight," Paillard et al. (1983) reported the case of a woman with damage to the left parietal cortex who was profoundly impaired in detecting tactile stimuli but could nonetheless correctly identify their location (also Rossetti et al., 1995). This stands in direct contrast to reports of neurological patients who were unable to accurately locat...
متن کاملLocalization of tactile stimuli depends on conscious detection.
Neurological reports of "tactile blindsight" suggest that the human somatosensory system can extract behaviorally useful information about the location of a tactile stimulus in the absence of conscious awareness that the stimulus occurred (Paillard et al., 1983; Rossetti et al., 1995). However, in a series of psychophysical experiments with neurologically intact subjects, we found no evidence f...
متن کاملColorful Tactile Stimuli. Association Between Colors and Tactile-Display Stimuli on Russell's Psychological Plane
Supplementing the presentation of colors with tactile displays has yet to be developed. This study used Russell’s affective plane to investigate the association between the rainbow colors and vibrotactile and variable-friction stimuli presented as tactile displays. A user study indicated that high-frequency and rhythmical tactile stimuli that were perceived as arousing were suitable for present...
متن کاملVariety of muscle responses to tactile stimuli.
Influences exerted by tactile stimuli on the muscle activity were investigated with two methods: (1) analysis of kinematics and electromyographic (EMG) activity of eight forelimb muscles during contact placing (CP) reactions elicited by tactile stimuli applied to the dorsal, medial or lateral sides of the paw in cats, and (2) the Hoffmann (H)-reflex technique to quantify the effects of the tact...
متن کاملTemporal recalibration to tactile-visual asynchronous stimuli.
Here we demonstrate that the perceptual system adapts to tactile-visual temporal asynchronies (i.e., temporal recalibration). Participants were exposed to a train of tactile and visual stimuli with a constant time lag (either -100ms, 0ms, or 100ms; with negative values indicating that the tactile stimulus came first). Following exposure, they were presented tactile-visual test stimulus pairs an...
