• To contribute to the knowledge of the cognitive differences existent between right-handed and left-handed evaluating the cognitive outcome in a group of adults right-handed and another group of left-handed of similar characteristic (age, gender, cultural level) by means of the Wechsler Adult Intelligence Scale (WAIS-III). Two groups were studied: one formed by 25 right-handed (RHG) and another formed by 25 left-handed (LHG). None of those subject of the study presented mental deficiency neither neurological dysfunctions. The age stocking was of 24.28 years, with a range between 20 and 28 years. There are not differences in the intellectual quotient (verbal and performance), among the two groups. The LHG obtains worse results that the right-handed in speed of prosecution and in the subtests of arithmetic and key, while the RHG has obtained better results in the subtest of incomplete figures. The LHG has a cognitive yield similar to that of the RHG, with slight deficiencies in activities of visoperceptual component. It becomes necessary to continue deepening in the neuropsychological and cognitive differences between right-handed and left-handed, since the cognitive outcome of the left-handed ones continues being a topic in discussion.
