年轻人和老年人接受了图片识别记忆的测试。Yonelinas高阈值（YHT）模型，2过程理论的正式实现，适合年轻人和老年人的响应分布数据显着优于正常的不等方差信号检测模型。与这一发现一致，两组均获得了非线性z转换的受试者工作特征曲线。从YHT模型的回忆估计显着高于年轻人比老年人。这种缺陷并不是记忆力普遍下降的结果;老年人表现出相当的总体准确性，事实上，他们的熟悉度得分并没有显着增加。这些结果的理论识别记忆和记忆缺陷与衰老的影响进行了讨论。
Young and older adults were tested on recognition memory for pictures. The Yonelinas high threshold (YHT) model, a formal implementation of 2-process theory, fit the response distribution data of both young and older adults significantly better than a normal unequal variance signal-detection model. Consistent with this finding, nonlinear z-transformed receiver operating characteristic curves were obtained for both groups. Estimates of recollection from the YHT model were significantly higher for young than for older adults. This deficit was not a consequence of a general decline in memory; older adults showed comparable overall accuracy and in fact a nonsignificant increase in their familiarity scores. Implications of these results for theories of recognition memory and the mnemonic deficit associated with aging are discussed.
