六名成年人参与者接受了针对对象和位置记忆的变化检测任务的测试，其中包括四种不同刺激类型的大组和小组。阻止测试表明，参与者在具有匹配参数和显示的单独对象和位置测试中表现相似。在混合测试中，参与者被告知他们将通过对象变化或位置变化进行测试；令人惊讶的是，他们对物体和位置的记忆几乎与单独测试时一样准确。相比之下，在大集条件下，意外探测测试试验的表现低于基线，其中参与者接受了与当前块相反的更改类型（例如在对象更改块期间的位置探测试验）的测试（在 13% 的试验中）。当使用这些项目类型的小集合（6）进行测试时，探针基线差异的减少进一步支持了这些探针测试结果。小集合需要记住位置和对象来解决对象位置混淆。这些结果共同表明，当被指示时，人类可以记住物体和位置，而准确性几乎没有损失，但在没有指示的情况下，人类无法学习这些上下文关联。
Six adult human participants were tested in change detection tasks for object and location memory with large and small sets of four different stimulus types. Blocked tests demonstrated that participants performed similarly in separate object and location tests with matched parameters and displays. In mixed tests, participants were informed that they would be tested with either object changes or location changes; surprisingly, they were nearly as accurate remembering both objects and locations as when either was tested alone. By contrast, in the large-set condition, performance was lower than baseline on surprise probe test trials in which participants were tested (on 13% of trials) with the change type opposite to the present block (e.g. location probe trials during the object change block). These probe-test results were further supported by the reduction in probe-baseline differences when tested with small sets (6) of these item types. Small sets required remembering locations and objects to resolve object-location confounds. Together these results show that humans can remember both objects and locations with little loss of accuracy when instructed to do so, but do not learn these contextual associations without instruction.
