Visual working memory contains a representation of certain image statistics (Victor & Conte, 2004), in addition to a pixel-by-pixel representation. Here, we show that the representation of statistics is more stable in time (up to 3000 ms) than the pixel-by-pixel representation, especially for changes in luminance and local high-order statistics, and is not affected by visual masking. Bilaterally symmetric arrays and arrays with local correlations are more readily encoded than random ones, but a change in the presence of bilateral symmetry, per se, contributes only modestly to the ability to detect that an array has changed.
视觉工作记忆除了包含逐像素表示外，还包含某些图像统计信息的表示（维克托和孔特，2004年）。在此，我们表明，统计信息的表示在时间上（长达3000毫秒）比逐像素表示更稳定，尤其是对于亮度和局部高阶统计量的变化，并且不受视觉掩蔽的影响。双侧对称阵列和具有局部相关性的阵列比随机阵列更容易被编码，但是双侧对称性本身的变化对检测阵列是否发生变化的能力贡献不大。
