Model‐oriented naming therapy: Testing predictions of a connectionist model

摘要: Background: The two versions of the connectionist model Dell and colleagues offer alternative explanations aphasic naming disorders (Dell, Schwartz, Martin, Saffran, & Gagnon, 1997; Foygel Dell, 2000). semantic‐phonological (SP) hypothesises impairments in lexical‐semantic or lexical‐phonological connections, weight‐decay (WD) assumes global either connection weights activation decay. In each version, a patient's error pattern picture is simulated to assess underlying disorder (connectionist “diagnosis”). A systematic comparison both model‐oriented therapy has not yet been performed. Moreover, if normalisation during recovery lesion‐specific, as suggested SP (Schwartz, Gahl, Sobel, 2006), this should be observable patient data. Aims: Predictions were made tested regarding relation between (1) diagnosis outcome, (2)...
