Categorization and Aging as measured by an adapted version of Wechsler’s similarities test

Abstract: L'objectif de cette recherche est d'étudier l'évolution avec le vieillissement du processus taxonomique impliqué dans une version adaptée du test des Similitudes de Wechsler, qui distingue la catégorisation des mots concrets versus abstraits. Deux groupes ont été constitués : 20 adultes jeunes (M =20ans, SD=1.36) et 20 adultes âgés (M =70ans, SD=4.66). Les résultats montrent un déclin de la catégorisation taxonomique avec l'âge, notamment pour les mots abstraits. L'effet de concrétude est donc observé mais seu… Show more

“…Only the latter showed differences between PDS and CDS groups. Proverb interpretation reflects semantic functions, relying on activity from the anterior temporal lobes, whilst the similarities test evaluates the capability to think abstractly to find resemblance between given words (Rozencwajg & Bertoux, 2008). Hence, an answer assuming difference in items that are similar shows the individual's inability to create a mental link between two elements, and the difficulty to perform categorisation…”

“…However, only the 60–69 age cohort demonstrated significantly lower scores compared to age 30–39 in both groups. Rozencwajg and Bertoux (2008) defined Similarities as grouping objects or words according to their common features at a high level of generality and found advantage in Similarities of typical young adults compared to older adults. Thus, although Similarities is considered a crystallised intelligence test, it is sensitive to age in populations with typical development and with intellectual disability (Rozencwajg & Bertoux, 2008).…”

“…Patients with frontal lobe damage may evidence more difficulties with tasks requiring fluid intelligence since acquired knowledge is more intact after frontal damage. The Similarities Test is a primary measure of the verbal comprehension factor index which some scholars indicate is more heavily influenced by crystallized intelligence (Rozencwajg & Bertoux, 2008;Ryan, Sattler, & Lopez, 2000). It is postulated that tests that measure fluid intelligence evidence more decline with age than tests that measure crystallized intelligence (Ryan et al, 2000).…”
