In two experiments participants retained a single color or a set of four spatial locations in memory. During a 5 s retention interval participants viewed either flickering dynamic visual noise or a static matrix pattern. In Experiment 1 memory was assessed using a recognition procedure, in which participants indicated if a particular test stimulus matched the memorized stimulus or not. In Experiment 2 participants attempted to either reproduce the locations or they picked the color from a whole range of possibilities. Both experiments revealed effects of dynamic visual noise (DVN) on memory for colors but not for locations. The implications of the results for theories of working memory and the methodological prospects for DVN as an experimental tool are discussed.
在两项实验中，参与者在记忆中保留单一颜色或一组四个空间位置。在5秒的保持间隔期间，参与者观看闪烁的动态视觉噪声或静态矩阵图案。在实验1中，使用识别程序评估记忆，参与者需指出特定测试刺激是否与记忆中的刺激匹配。在实验2中，参与者尝试重现位置或从一系列可能性中挑选颜色。两项实验均揭示了动态视觉噪声（DVN）对颜色记忆的影响，但对位置记忆没有影响。讨论了结果对工作记忆理论的意义以及DVN作为实验工具的方法学前景。
