Background: Information from speech and gesture is often integrated to comprehend a message. This integration process requires the appropriate allocation of cognitive resources to both the gesture and speech modalities. People with aphasia are likely to find integration of gesture and speech difficult. This is due to a reduction in cognitive…

Purpose: Individuals with primary progressive apraxia of speech (PPAOS) have apraxia of speech (AOS) in which disruptions in articulation or prosody predominate the speech pattern, referred to, respectively, as phonetic or prosodic subtypes. Many develop aphasia and/or dysarthria. Past research has demonstrated that simple temporal acoustic…

The statistical information that estimates the magnitude of communication disorders among Egyptian children is scarce. At Mansoura University, a prospective study was performed to identify communication disorders among nursery school children in Dakahlia governorate, Egypt to estimate the problem's size among Arabic-speaking Egyptian children…

Alignment refers to the interactive use of similar words to accomplish a linguistic and cognitive "common ground" in conversations. Alignment is thought to be unconscious, relying on priming mechanisms. This occurs uniquely in conversational contexts and has been shown in choices of words, grammatical constructions, and even indirect…

Wernicke's aphasia is a condition which results in severely disrupted language comprehension following a lesion to the left temporo-parietal region. A phonological analysis deficit has traditionally been held to be at the root of the comprehension impairment in Wernicke's aphasia, a view consistent with current functional neuroimaging which finds…

The effect of increasing word length on the articulatory dynamics (i.e. duration, distance, maximum acceleration, maximum deceleration, and maximum velocity) of consonant production in acquired apraxia of speech was investigated using electromagnetic articulography (EMA). Tongue-tip and tongue-back movement of one apraxic patient was recorded…
