Aging affects hemispheric asymmetry on a competing speech task.
This study examined the effects of aging on the hemispheric asymmetry of event-related potentials (ERPs) evoked by morphosyntactic anomalies in a competing speech paradigm. The experimental groups consisted of children, young adults, and elderly persons. The ERPs were recorded from 32 scalp sites while participants listened to a continuous narrative presented quasidichotically via loudspeakers....
متن کاملAging and the vulnerability of speech to dual task demands.
Tracking a digital pursuit rotor task was used to measure dual task costs of language production by young and older adults. Tracking performance by both groups was affected by dual task demands: time on target declined and tracking error increased as dual task demands increased from the baseline condition to a moderately demanding dual task condition to a more demanding dual task condition. Whe...

هدف اصلی این تحقیق بررسی تاثیر افزایش میزان پیچیدگی تکالیف مکالمه محور بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 15 الی 18 سال درسطح pre-intermediate از طریق petو vhs تست به عنوان شرکت کنندگان در تحقیق انتخاب شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی دو تکلیف ساده و پیچیده را طی 2 جلسه انجام...
Speech perception without traditional speech cues.
A three-tone sinusoidal replica of a naturally produced utterance was identified by listeners, despite the readily apparent unnatural speech quality of the signal. The time-varying properties of these highly artificial acoustic signals are apparently sufficient to support perception of the linguistic message in the absence of traditional acoustic cues for phonetic segments.
متن کاملAudio-visual speech perception without speech cues
A series of experiments was conducted in which listeners were presented with audio-visual sentences in a transcription task. The visual components of the stimuli consisted of a male talker’s face. The acoustic components consisted of : (1) natural speech (2) envelope-shaped noise which preserved the duration and amplitude of the original speech waveform and (3) various types of sinewave speech ...
