Nonlinear timing and language processing in norm and pathology

Abstract

Many experimental data have indicated that nonlinear temporal processing plays a crucial role in human cognition, including our language communication. We summarize briefly the neuropsychological findings on typical temporal frame underlying language processing. Concentrating on millisecond (the high-frequency processing system) and multisecond (the low-frequency system) timingmechanisms, we provide evidence on temporal dynamics of both speech reception and expression with the special concern on temporal integration and temporal resolution of the signal. The examples of nonlinear temporal processing are discussed in cross-linguistic scenario. Finally, we provide some examples on time distortion in language-disordered population and discuss future applications of training in temporal processing in amelioration of language functions.
