Second revision May 16 , 2003 . pass judgment May 19 , 2003SummaryThe causes of variability of performance by individual subjects have rarely been investigated , although excessive variability or discrepancy may be a functionally significant grammatical constituent for many real-life activities . Our objective was to determine whether patients with focal frontal brain lesions have excessive individual performance variability .

thirty-six patients with focal frontal (n 25 ) or non-frontal (n 11 ) lesions were compared with 12 control subjects on different measures of intra-individual variability : dispersion inside a interrogatory academic term and consistency across testing sessions . Four reaction time tasks , varying in levels of complexity and based on a model of detection utilize feature integration , were administered . Following the first test session , 22 patients and 10 controls returned for two subsequent test sessions , which permitted the judicial decision of consistency of performance . Measures of abnormal dispersion of performance on these tests were observe in frontal patients only (except those with exclusively inferior medial damage . Disturbances in consistency of performance were observed primarily in patients with frontal lesions Damage to the frontal lobes impairs...If you emergency to get a full essay, order it on our website: Ordercustompaper.com
