回顾了表明非语言短期记忆具有独特的视觉和空间/顺序成分的证据。描述了一种新的测试，即视觉模式测试（VPT），该测试旨在测量短期视觉记忆，很大程度上去除了其空间顺序成分。对健康受试者和脑损伤患者进行的 VPT 和 Corsi 块测试的相关研究表明，视觉能力和顺序能力之间存在差异。患者表现出的双重解离支持了这种功能分离。此外，在选择性干扰实验中，发现 VPT 和 Corsi 测试分别显示出视觉和空间顺序辅助任务干扰的双重解离模式。目前的结果与文献中的其他发现进行了讨论，得出的结论是，非语言短期记忆确实可以被视为包含不同的视觉和空间顺序成分。 VPT 将成为测量视觉成分的有用神经心理学工具。 (C) 1999 Elsevier Science Ltd. 保留所有权利。
Evidence showing that non-verbal short-term memory has distinct visual and spatial/sequential components is reviewed. A new test, The Visual Patterns Test (VPT), which was designed to measure short-term visual memory largely shorn of its spatio-sequential component, is described. Correlational studies of the VPT and the Corsi Blocks Test with healthy subjects and brain-damaged patients indicate a separation between visual and sequential abilities. This separation of function is supported by double dissociations shown by patients. Moreover, in a selective interference experiment, the VPT and the Corsi tests were found to show a double dissociation pattern of interference from visual and spatio-sequential subsidiary tasks, respectively. The present results are discussed in relation to other findings in the literature, and it is concluded that non-verbal short-term memory can indeed be viewed as comprising distinct Visual and spatio-sequential components. The VPT will be a useful neuropsychological instrument for measuring the visual component. (C) 1999 Elsevier Science Ltd. All rights reserved.
