摘要：Executive functions can be impaired after a right hemisphere stroke. This paper aims to verify whether there are differences between a clinical and a control group regarding their executive functions’ control, as well as to describe the frequency of executive deficits in a right-brain-damaged sample. Twenty five adults with a single right hemisphere stroke (clinical group) and 25 non-brain-damaged adults, matched for education and age levels (control group) were assessed with the following instruments to measure executive functions: Verbal Digit Span, Stroop Test, Trail Making Test, Hayling Test and Wisconsin Card Sorting Test (brief version with 48 cards). Group comparison demonstrated significant differences in attention levels. However, the analysis of case-by-case performance showed a higher frequency of inhibition and cognitive flexibility deficits, evaluated by Stroop, Hayling and Wisconsin tests. Cluster studies are suggested in order to characterize the performance in each executive component.
