The Effect of Spatial Disparity on the Integration of Auditory and Tactile Information
نویسنده
چکیده
Spatial origin is an important cue for humans to determine whether auditory and tactile signals originate from the same event/object or not. This paper addresses spatial factors involved in the integration of auditory and tactile information. Perceptual threshold values for auditory-tactile spatial origin disparity were measured using tactile information and sound such as those generated by touching (scraping) an abrasive paper. The results of the study show that the minimum angle subjects need to notice that the locations of the auditory and tactile events do not coincide is 5.3°. Simultaneously presented tactile stimulation enlarges the auditory localization blur in the horizontal plane. The results show that the perceived location of auditory stimuli is influenced by tactile stimulation.

متن کاملOscillatory activity in auditory cortex reflects the perceptual level of audio-tactile integration
Cross-modal interactions between sensory channels have been shown to depend on both the spatial disparity and the perceptual similarity between the presented stimuli. Here we investigate the behavioral and neural integration of auditory and tactile stimulus pairs at different levels of spatial disparity. Additionally, we modulated the amplitudes of both stimuli in either a coherent or non-coher...

The rural centers integrations in the city which in some countries have been named as “urban villages” are the consequence of rapid urbanization and accelerated growth of our city. Since the rural centers integration in the city has been often without any plan, it has had various consequences on the environmental, physical, economical and social aspects. The present study has paid attention to ...
متن کاملThe effect of bottom-up and top-down auditory program training on the development of children's auditory processing skills
Although there have been several previous investigations on the role of auditory training for the development of auditory processing skills, it still remains unknown whether children with auditory processing difficulties can get improved auditory skills after exposure to a multi-modal training experience comprising both visual and tactile stimuli. The present study, therefore, attempted to use ...
