Ji et al. investigated the unit of working memory manipulation. Participants were asked to update either the color or location of memorized information. Task difficulty depended on the number of Boolean maps involved, rather than the number of objects, suggesting that Boolean maps, not objects, are the units of manipulation.

测试工作内存操作的单元


Ji 等人研究了工作记忆操纵的单位。参与者被要求更新记忆信息的颜色或位置。任务难度取决于所涉及的布尔映射的数量，而不是对象的数量，这表明布尔映射（而不是对象）是操作单元。
