大鼠对刺激P（例如，家庭物品）的探索在其直接或间接暴露后减少，并被认为是识别记忆的指示。证明间接物体识别的程序包括物体P与刺激X的初始呈现（以及物体Q与刺激Y的初始呈现）。在测试中，刺激X与物体P和Q一起呈现，大鼠对Q的探索超过了对P的探索。这里的一种解释是，在测试中，刺激X的呈现联想地激活了对物体P的记忆，这相对于Q减少了对P的探索。这种表现仅仅是由不熟悉的X和q的组合产生的一种新的刺激模式的结果。作者修改了这一过程，以减少这种过程的可能性。他们的程序包括先呈现PX和QY，然后再单独呈现刺激X。在随后的测试中，物体P和Q被呈现，但刺激X被移除。作者发现，尽管有这些修改，对Q的探索仍然大于对P的探索，并讨论了识别记忆中间接联想过程的一些理论含义。
Rats' exploration of stimulus P (e.g., a domestic object) is reduced following either its direct exposure or its indirect exposure and is taken to indicate recognition memory. Procedures for demonstrating indirect object recognition involve an initial presentation of object P with stimulus X (and of an object Q with stimulus Y). On test, stimulus X is presented with objects P and Q and rats' exploration of Q exceeds their exploration of P. One interpretation here is that the presentation of stimulus X on test associatively activates the memory of object P, which diminishes exploration of P relative to Q. It is possible, instead, that performance is simply the result of a novel pattern of stimulation generated by the unfamiliar combination of X and Q. The authors modified this procedure to reduce the likelihood of such a process. Their procedure involved first the presentation of PX and QY before the presentation of stimulus X alone. During the test that followed, objects P and Q were presented but stimulus X was removed. The authors found that exploration of Q remained greater than that of P despite these modifications and discuss some theoretical implications of indirect, associative processes in recognition memory.
