Domain-specific systems were divided into phonological loop and visual-spatial sketchpad according to modalities of information and thus is often called as modality-specific systems. WM model proposed by Baddeley 6– 8) is one of the most influential WM models and consists of two domain-specific systems and a domain-general system. Deficits in WM are reported in many psychiatric diseases as WM is deeply related to clinical symptoms, other complex cognitive functions, and activities of daily living. 1) From a clinical perspective, WM is fairly important. Working memory (WM) is a cognitive system that allows for transient storage and manipulation of given information. Keywords: Modality-specific working memory, WAIS-IV, WMS-IV Our study supports a modality model of WM, or the existence of modality-specific WM systems, and thus poses a clinical significance of assessing both auditory and visual WM tests. ResultsĬFA results demonstrated that a two factor model fits the data better than one-factor model as expected. Confirmatory factor analysis (CFA) was used to observe whether WM measures fit better to a one-factor or two-factor model. WM subtests of Korean version of Wechsler Adult Intelligence Scale-IV and Korean version of Wechsler Memory Scale-IV were administered to assess WM. MethodsĪ total of 115 patients were diagnosed on the basis of DSM-IV diagnostic criteria and with MINI-Plus 5.0, a structured diagnostic interview. To do this, we administered the most recent and universal clinical WM measures in a mixed psychiatric sample. This study was to identify whether working memory (WM) can be clearly subdivided according to auditory and visual modality.
