Structure of Auditory Sentence Comprehension by Conduction Aphasia.

Sentence Comprehension in Aphasia

We show in this chapter that selective aphasic deficits dissociate distinct language processing systems. To this end, we focus on disruptions of lexical access that appear to implicate initial stages of sentence comprehension. The analyses we present turn on comparisons between agrammatic (Broca's) aphasic patients and paragrammatic (Wernicke's) aphasic patients. By the former we mean roughly, ...

Tracking Passive Sentence Comprehension in Agrammatic Aphasia.

People with agrammatic aphasia often experience greater difficulty comprehending passive compared to active sentences. The Trace Deletion Hypothesis (TDH; Grodzinsky, 2000) proposes that aphasic individuals cannot generate accurate syntactic representations of passive sentences and, hence, use an agent-first processing strategy which leads to at-chance performance. We tested this claim using th...

Treatment of Auditory Comprehension on Aphasia

Aphasia is a systemic disturbance of speech, revealing in the complete loss or partial loss of speech and local lesion caused by one or more of the speech areas in the brain. In most cases, aphasia occurs in adults, however, it is also possible in children, if the brain injury occurred after it had been formed, at least partially. The term ‘aphasia’ is derived from the Greek ‘fasio’ (say) and t...

A MEG investigation of single-word auditory comprehension in aphasia.

PURPOSE To explore whether individuals with aphasia exhibit differences in the M350, an electrophysiological marker of lexical activation, compared with healthy controls. METHOD Seven people with aphasia, 9 age-matched controls, and 10 younger controls completed an auditory lexical decision task while cortical activity was recorded with magnetoencephalography. There were 2 stimulus conditions...
