The task of lexical decision demands the functioning of the phonological loop to identify and discriminate strings of sounds and lexical knowledge to identify if this string can be taken as a real word or pseudo-word. Objective To verify the effect of schooling on the performance of healthy elderly in lexical decision tasks, in the auditory modality. Methods 23 Participants, aged sixty year...

The patterns of semantic errors in speaking and writing are used to constrain claims about the structure of lexical access mechanisms in speech and written language production. It is argued that it is not necessary to postulate a modality-neutral level of lexical representation (lemma) that is intermediate between lexical-semantic representations and modality-specific lexical representations. A...

Background The purpose of the study was to analyze naming errors in patients with Alz-heimer's disease in comparison to healthy subjects and determine the underlying cause of naming errors in these patients. Method In this study, we included 35 healthy elderly subjects, 23 patients with mild Alzheimer's disease, and 23 with moderate Alzheimer's disease. Forty-five images were used to determin...

This paper presents an investigation of lexical chaining (Morris and Hirst, 1991) for measuring discourse coherence quality in test-taker essays. We hypothesize that attributes of lexical chains, as well as interactions between lexical chains and explicit discourse elements, can be harnessed for representing coherence. Our experiments reveal that performance achieved by our new lexical chain fe...

We describe an analysis of speech errors on a confrontation naming task in a man with progressive speech degeneration of 10-year duration from Pick's disease. C.S. had a progressive non-fluent aphasia together with a motor speech impairment and early assessment indicated some naming impairments. There was also an absence of significant phonological or semantic impairment. In order to examine na...

Objectives: The lexical-level deficits are one of the hallmark limitations observed in early school-age children with specific language impairment. These problems are the predictors of reading problems and poor performance at school. Most studies in Persian-speaker children with specific language impairment have focused on syntax and morphology and the naming errors profile of these children ar...
