Abstract:
Language comprehension depends on the ability to temporally process the periodic structure of the language signal. In this study we investigate temporal processing of Sign Language (LSE), isolating the specific contribution of signal modality. Twenty-three highly proficient hearing users of LSE performed an intelligibility task with these three types of materials, manipulated with different levels of temporal distortion. The results show that the distortion differently affects the intelligibility of these signals. Conversely, in LSE and the visual non-linguistic task greater temporal distortion led to a gradual and constant reduction in intelligibility with no clear threshold. LSE is more resilient to temporal manipulation compared to the visual non-linguistic signal.
