Spatio-temporal constraints for auditory--visual integration.
The perceptual coherence of auditory and visual information is achieved by integrative brain processes. Specialized single neurons with spatial and temporal interactions of auditory and visual stimuli have been demonstrated by several neurophysiological studies. The present, psychophysical, study investigates possible perceptual correlates of these neuronal features. Subjects had to indicate th...

چکیده مهارت شنیداری برای مدتهای طولانی در آموزش ، تحقیق و ارزیابی مورد غفلت قرار گرفته است. اگرچه در سالهای اخیر به خاطر اهمیت قابل ملاحظه این توانائیها در آموزش و آزمون زبان ، توجه بیشتری به توانائیهای شنیداری شده است. هم چنانکه درک شنیداری در آموزش و ارزیابی زبان دوم اهمیت فزاینده ای می یابد محققین سعی نموده اند تا ماهیت مهارتهای مستتر در مهارت شنیداری را مورد بررسی و مطالعه قرار دهند. هدف ...
15 صفحه اولBayesian integration of visual and auditory signals for spatial localization.
Human observers localize events in the world by using sensory signals from multiple modalities. We evaluated two theories of spatial localization that predict how visual and auditory information are weighted when these signals specify different locations in space. According to one theory (visual capture), the signal that is typically most reliable dominates in a winner-take-all competition, whe...

spatial correspondence A systematic relationship falling short of registry between the unimodal receptive field locations in individual multimodal neurons. Correspondence can also occur between the receptive fields of neighboring unimodal neurons that respond to different modalities. linear function A function f(x)1⁄4mx, wherem is a constant. Linear functions have the property of superimposibil...
متن کاملTemporal window of integration in auditory-visual speech perception.
Forty-three normal hearing participants were tested in two experiments, which focused on temporal coincidence in auditory visual (AV) speech perception. In these experiments, audio recordings of/pa/and/ba/were dubbed onto video recordings of /ba/or/ga/, respectively (ApVk, AbVg), to produce the illusory "fusion" percepts /ta/, or /da/ [McGurk, H., & McDonald, J. (1976). Hearing lips and seeing ...
