Sound alters tactile motion perception
Recently Sekuler et al. (Nature, 1997) investigated the motion-bounce illusion and found that sound can influence ambiguous visual motion perception. Here we investigated the motion-bounce illusion in the tactile-auditory domain. Using a vibro-tactile belt consisting of 7 vibrators we generated tactile apparent motion stimuli by sequentially activating neighboring motors with an onset of 200ms ...
متن کاملThe Application of Tactile Experience in Urban Perception
Urban perception is the result of mutual transaction between human and environment and the process of perception is developed through the three continuous steps of “sensation”, “perception” and “cognition”. In the first step (sensorial perception), the environmental signals are received via sensorial sensors and each different sense based on its own essence, performance and ability has its own ...

متن کاملStriatal Dopamine Depletion Patterns and Early Non-Motor Burden in Parkinsons Disease
BACKGROUND The mechanism underlying non-motor symptoms in Parkinson's disease has not yet been elucidated. In this study, we hypothesized that Parkinson patients with more non-motor symptoms have a different pattern of striatal dopamine depletion, particularly in areas other than the sensorimotor striatum, compared to those with fewer non-motor symptoms. METHODS We conducted a prospective sur...
متن کاملCategorical perception of tactile distance.
The tactile surface forms a continuous sheet covering the body. And yet, the perceived distance between two touches varies across stimulation sites. Perceived tactile distance is larger when stimuli cross over the wrist, compared to when both fall on either the hand or the forearm. This effect could reflect a categorical distortion of tactile space across body-part boundaries (in which stimuli ...
