大鼠对新物体的自然偏好已被用作测试物体识别的行为指标。在这一系列实验中，标准自发识别任务被扩展到其他类型的识别记忆;位置记忆（识别出物体位于先前没有物体的位置），就地对象内存（识别特定对象已与另一对象改变位置）和上下文记忆（认识到熟悉的对象处于与之前遇到的对象不同的环境中）。我们还包括一个标准的测试对象识别成功的歧视主要依赖于视觉线索。此外，我们还研究了在测试阶段的3分钟内，物体的差分探索是如何变化的。结果表明，大鼠对所有测试条件下的变化都很敏感，并且在3分钟的测试阶段内，辨别水平各不相同。在标准条件和情境条件下，前2 min是最敏感的时间段。在涉及位置改变的两种情况下，歧视只在第一分钟明显。(C)1999 Elsevier Science B.

The natural preference for novel objects which is displayed by rats has been used as a behavioural index to test object recognition. In this series of experiments the standard spontaneous recognition task was extended to look at other types of recognition memory; memory for place (recognition that an object is in a location where previously there had been no object), memory for object in place (recognition that a specific object has changed position with another object) and memory for context (recognition that a familiar object is in a context different to that in which it was previously encountered). We also included a standard test of object recognition in which successful discrimination relied primarily on visual cues. In addition, we looked at how the differential exploration of objects varied within the 3 min of the test phase. The results showed that rats were sensitive to the changes made in all of the test conditions and that the level of discrimination varied within the 3 min test phase. In the standard condition and the context condition, the first 2 min were found to be the most sensitive period. In the two conditions involving a position change, discrimination was only evident in the first minute. (C) 1999 Elsevier Science B.V. All rights reserved.
