在过去的十年中，通过颜色产生反应的数学建模在理解视觉工作记忆方面取得了重大进展。在延迟颜色估计任务中，参与者需要记住一组彩色方块，几秒钟后要求参与者通过单击色轮来重现这些颜色。这些反应的错误程度通过数学模型来表征，该数学模型估计工作记忆精度和参与者记住的项目比例。颜色记忆的标准数学模型假设内存中保存的项目通过内存被记住，以获取有关特定研究的颜色阴影的精确细节。我们认为该模型目前的形式是不完整的，因为没有提供机制来记住所研究颜色的粗略类别。在目前的工作中，我们弥补了这一遗漏，并提出了一个视觉工作记忆模型，其中包括连续记忆表示和分类记忆表示。在两个实验中，我们表明我们的新模型优于这种标准建模方法，这表明分类表示应该由视觉工作记忆的数学模型来解释。
In the last decade, major strides have been made in understanding visual working memory through mathematical modeling of color production responses. In the delayed color estimation task, participants are given a set of colored squares to remember and a few seconds later asked to reproduce those colors by clicking on a color wheel. The degree of error in these responses is characterized with mathematical models that estimate working memory precision and the proportion of items remembered by participants. A standard mathematical model of color memory assumes that items maintained in memory are remembered through memory for precise details about the particular studied shade of color. We contend that this model is incomplete in its present form because no mechanism is provided for remembering the coarse category of a studied color. In the present work we remedy this omission and present a model of visual working memory that includes both continuous and categorical memory representations. In two experiments we show that our new model outperforms this standard modeling approach, which demonstrates that categorical representations should be accounted for by mathematical models of visual working memory.
