物体识别任务是评估啮齿动物记忆功能的常用测试。本文对目标识别数据分析的各个方面进行了探讨。利用一组实验研究和实际数据集，表明绝对区别测度（d1）的行为不同于比率测度（d2和d3）。此外，有人建议，除了群体差异之外，人们还应该研究每个群体是否实际上区分了小说和熟悉的物体。为此目的，建议使用没有歧视的有效组。此外，基于48个目标识别任务的研究表明，识别性能并没有明显下降到零以下。因此，如果可以排除地点或对象偏差，则允许进行单侧测试。最后，研究表明，勘探水平的差异可能会影响群体差异的统计评价。对统计分析提出了几点建议。(C) 2012 Elsevier B.V.版权所有
The object recognition task is a commonly used test for the assessment of memory functions in rodents. In this paper different aspects concerning the analysis of object recognition data are discussed. Using a set of experimental studies and fictive data sets, it was shown that the absolute discrimination measure (d1) behaves different from the ratio measures (d2 and d3). Furthermore, it is suggested that, besides group differences, one should also examine whether each individual group actually discriminates between the novel and the familiar object. For this purpose, the use of a fictive group showing no discrimination is advisable. Furthermore, on basis of 48 object recognition task studies it is shown that discrimination performance does not fall significantly below zero. Therefore one-sided testing is allowed, provided that place- or object biases can be ruled out. Finally, it was shown that differences in exploration levels may affect the statistical evaluation of group differences. Several suggestions for statistical analysis are given. (C) 2012 Elsevier B.V.
