Prediction of Chinese Reading Fluency by Verbal and Non-verbal Visual Attention Span Measures

Non-Verbal and Verbal Fluency in Prodromal Huntington's Disease.

BACKGROUND This study examines non-verbal (design) and verbal (phonemic and semantic) fluency in prodromal Huntington's disease (HD). An accumulating body of research indicates subtle deficits in cognitive functioning among prodromal mutation carriers for HD. METHODS Performance was compared between 32 mutation carriers and 38 non-carriers in order to examine the magnitude of impairment acros...

The visual attention span deficit in dyslexia is visual and not verbal.

The visual attention (VA) span deficit hypothesis of dyslexia posits that letter string deficits are a consequence of impaired visual processing. Alternatively, some have interpreted this deficit as resulting from a visual-to-phonology code mapping impairment. This study aims to disambiguate between the two interpretations by investigating performance in a non-verbal character string visual cat...

Verbal fluency in schizotypy Less words, more words: psychometric schizotypy and verbal fluency

Positive and negative symptoms of schizophrenia have been differentially associated with irregularities in verbal production, suggesting the involvement of different underlying mechanisms in psychotic symptomatology. In view of that, the present investigation examined whether the amount of verbal production would be also differentially associated with negative and positive symptoms of psychomet...

What do verbal fluency tasks measure? Predictors of verbal fluency performance in older adults

This study examined the contributions of verbal ability and executive control to verbal fluency performance in older adults (n = 82). Verbal fluency was assessed in letter and category fluency tasks, and performance on these tasks was related to indicators of vocabulary size, lexical access speed, updating, and inhibition ability. In regression analyses the number of words produced in both flue...
