通常通过认知复杂的跨度任务测量的工作记忆（WM）能力与健康成年人的高阶认知能力相关。 The goals of the present study were to determine: 1) if a more focused measure of visual WM storage capacity would show similar higher-order ability correlations in healthy adults and in people with schizophrenia (PSZ) thereby demonstrating the importance of simple storage capacity, 2) determine if the illness alters the pattern of correlations across cognitive domains, and, 3) evaluate whether between-group differences in WM capacity could account for the generalized cognitive impairment in PSZ.
九十九个PSZ和77个健康对照（HCS）完成了视觉WM变更本地化任务，Wechsler缩写的智能量表（WASI）和Matrics共识认知电池（MCCB）。
在所有认知措施上，PSZ的表现都比HC差。 WM容量的组间效应大小很大（d = 1.11）。 WM与WASI和MCCB的性能牢固相关，在各组之间相关的大小或模式没有显着差异。当组合组合时，WM容量在R = 0.68与MCCB复合评分时相关，r = 0.56，WASI估计全尺度IQ。 WM容量约占整个WASI和MCCB的组间差异的40％。
WM存储能力的一个简单衡量标准与HC和PSZ中WASI和MCCB评估的高阶认知能力有牢固的关系。 WM容量降低可能是PSZ一般认知障碍的关键决定因素。
Working memory (WM) capacity, typically measured with cognitively complex span tasks, is correlated with higher-order cognitive abilities in healthy adults. The goals of the present study were to determine: 1) if a more focused measure of visual WM storage capacity would show similar higher-order ability correlations in healthy adults and in people with schizophrenia (PSZ) thereby demonstrating the importance of simple storage capacity, 2) determine if the illness alters the pattern of correlations across cognitive domains, and, 3) evaluate whether between-group differences in WM capacity could account for the generalized cognitive impairment in PSZ. Ninety-nine PSZ and 77 healthy controls (HCs) completed a visual WM change localization task, the Wechsler Abbreviated Scale of Intelligence (WASI) and the MATRICS Consensus Cognitive Battery (MCCB). PSZ performed more poorly than HC on all cognitive measures. The between-group effect size for WM capacity was large (d = 1.11). WM robustly correlated with WASI and MCCB performance with no significant differences in the magnitude or pattern of correlations across groups. When the groups were pooled, WM capacity correlated at r=0.68 with MCCB composite score and at r=0.56 with WASI estimated Full Scale IQ. WM capacity accounted for approximately 40% of the between-group variance across the WASI and MCCB. A simple measure of WM storage capacity is robustly associated with the higher-order cognitive abilities assessed by the WASI and MCCB in both HC and PSZ. WM capacity reduction may be a critical determinant of the general cognitive impairment in PSZ.
