Language deficits and the theory of syntax

Area of Science:

• Linguistics
• Psycholinguistics
• Neurolinguistics

Background:

• Agrammatism, a language disorder, presents significant challenges in sentence comprehension.
• Existing structural accounts of agrammatism lack a unified explanation for experimental findings.

Purpose of the Study:

• To propose a new structural account of agrammatism based on current syntactic theory.
• To provide a unified explanation for experimental data in agrammatism sentence comprehension.

Main Methods:

• Analysis of experimental findings from sentence comprehension studies in agrammatism.
• Modification of a syntactic model by imposing a special condition on the construct 'trace'.

Main Results:

• The proposed minimal change to the syntactic model successfully accounts for all available experimental data.
• The new model is shown to be preferable to other recently proposed structural accounts of agrammatism.

Conclusions:

• The proposed structural account offers a unified explanation for agrammatism.
• The findings have significant implications for models of language processing and understanding agrammatism.
