视觉工作记忆通常被建模为具有固定数量的槽。我们通过评估视觉工作记忆变化检测任务中参与者的受试者操作特征（ROC）来测试该模型。ROC图产生斜率为1.0的直线，这是全或无记忆表征的一个特征。正式的模型评估产生的证据高度一致的离散固定容量模型的工作记忆这项任务。
Visual working memory is often modeled as having a fixed number of slots. We test this model by assessing the receiver operating characteristics (ROC) of participants in a visual-working-memory change-detection task. ROC plots yielded straight lines with a slope of 1.0, a tell-tale characteristic of all-or-none mnemonic representations. Formal model assessment yielded evidence highly consistent with a discrete fixed-capacity model of working memory for this task.
