Several different sources of evidence support the idea that visuo-spatial working memory can be segregated into separate cognitive subsystems. However, the nature of these systems remains unclear. Recently we reported data from neurological patients suggesting that information about visual appearance is retained in a different subsystem from information about spatial location. In this paper we report latency data from neurologically intact participants showing an experimental double dissociation between memory for appearance and memory for location. This was achieved by use of a selective dual task interference technique. This pattern provides evidence supporting the segregation of visuo-spatial memory between two systems, one of which supports memory for stimulus appearance and the other which supports memory for spatial location.
有几种不同的证据来源支持这样一种观点，即视觉空间工作记忆可以被划分为不同的认知子系统。然而，这些系统的本质仍不清楚。最近我们报告了来自神经疾病患者的数据，表明关于视觉外观的信息与关于空间位置的信息保留在不同的子系统中。在本文中，我们报告了来自神经功能正常参与者的潜伏期数据，这些数据显示了外观记忆和位置记忆之间的实验性双重分离。这是通过使用选择性双任务干扰技术实现的。这种模式提供了证据，支持视觉空间记忆在两个系统之间的分离，其中一个系统支持刺激外观的记忆，另一个系统支持空间位置的记忆。
