CARTHERY-GOULART, Maria Teresa et al. Dissociation Between Living and Nonliving Concepts: Investigation of Category Specific Effects in Semantic Processing Using the Cambridge Battery of Semantic Memory Tests. Psicol. pesq. [online]. 2013, vol.7, n.1, pp.108-120. ISSN 1982-1247.

This study investigated dissociations between nouns representing living and nonliving entities in cognitively unimpaired adults and in two patients, one with Semantic Dementia (SD) and another with Alzheimer's disease (AD), using tests from the Cambridge Battery of Semantic Memory Tests. Among controls a higher number of correct responses in naming, definition and verbal fluency was observed in nouns representing living concepts but differences did not reach statistical significance when we controlled for sociodemographic variables correlated to the tasks. The description of the performance of two patients allowed for recognition of different profiles in the tasks. It is suggested that the patient with SD presented a double-dissociation compared to controls and to the patient with AD. Results are discussed in terms of models of semantic memory organization and neuroanatomical correlates.

Keywords : Semantic memory; semantic dementia; Alzheimer's disease; neuropsychological assessment.
