Data from the literature on the effect of lesions upon recognition memory in the monkey have been examined. On the basis of percentage scores the published data can be interpreted as showing that the ability to recognize a previously seen object decays faster in macaques with brain lesions than it does in normal animals. A reanalysis of the extensive data in terms of d' of Signal Detection Theory or by arcsine transform suggests, on the contrary, that the rate of decay from 0 to 600 s, is essentially the same in normal animals and in those with lesions (particularly temporal lobe lesions). Indeed, in d' or arcsine terms, the effect of the lesions is fully developed at the shortest times used, and shows no increase as a function of the delay between initial presentation and test. Thus, very different conclusions stem from the choice of scale.
我们已对文献中关于损伤对猴子识别记忆影响的数据进行了研究。根据百分比得分，已发表的数据可以解释为表明，与正常动物相比，患有脑部损伤的猕猴识别先前见过的物体的能力衰退得更快。然而，根据信号检测理论的d'值或通过反正弦变换对大量数据进行重新分析表明，正常动物和有损伤的动物（特别是颞叶损伤）从0到600秒的衰退率基本相同。实际上，从d'值或反正弦值来看，损伤的影响在使用的最短时间内就已完全显现，并且不会随着初始呈现和测试之间的延迟而增加。因此，由于尺度的选择而产生了截然不同的结论。
