Grammatical Complexity and Aphasic Speech

the effect of task complexity on lexical complexity and grammatical accuracy of efl learners’ argumentative writing

بر اساس فرضیه شناخت رابینسون (2001 و 2003 و 2005) و مدل ظرفیت توجه محدود اسکهان (1998)، این تحقیق تاثیر پیچیدگی تکلیف را بر پیچیدگی واژگان و صحت گرامری نوشتار مباحثه ای 60 نفر از دانشجویان زبان انگلیسی بررسی کرد. میزان پیچیدگی تکلیف از طریق فاکتورهای پراکندگی-منابع تعیین شد. همه ی شرکت کنندگان به صورت نیمه تصادفی به یکی از سه گروه: (1) گروه موضوع، (2) گروه موضوع + اندیشه و (3) گروه موضوع + اندی...

Grammatical Complexity and Inference

Sentence segmentation of aphasic speech

Automatic analysis of impaired speech for screening or diagnosis is a growing research field; however there are still many barriers to a fully automated approach. When automatic speech recognition is used to obtain the speech transcripts, sentence boundaries must be inserted before most measures of syntactic complexity can be computed. In this paper, we consider how language impairments can aff...

Modelling Paraphasias in Normal and Aphasic Speech

We model word substitution errors made by normal and aphasic speakers with an interactive activation model of lexicalization. This comprises a three-layer architecture of semantic, lexical, and phonological units. We test four hypotheses about the origin of aphasic word substitutions: that they result from pathological decay, loss of within-level inhibitory connections, increased initial random...

Impoverishment of grammatical features in a non fluent aphasic speaker : the grammatical nature of minimal structures

The present study is an examination of an Italian aphasic speaker (M.R.) with non-fluent speech following a focal lesion in the left hemisphere. We develop an explanation of M.R.'s language impairment compatible with theories of generative syntax and with some observations on parsing strategies. The explanatory framework we adopt considers the grammar to be an integral part of on-line language ...
