研究人员向16名临床抑郁症患者和16名健康对照者展示了一组情绪面部表情，并要求他们识别每张脸所描绘的情绪。随后，他们对这些面孔进行了识别记忆测试。两组之间从面部识别情绪的能力没有差异。所有参与者对情绪表情的识别都比中性表情更准确，其中对快乐表情的识别最准确。在识别记忆阶段，抑郁症患者对悲伤表情的记忆优于中性表情，对快乐表情的记忆优于中性表情。相反，与中性表情相比，对照组对快乐表情的记忆更强，而对悲伤表情的记忆更差。这些结果是根据Williams， Watts, MacLeod, and Mathews（1997）提出的抑郁症认知模型来讨论的。
Sixteen clinically depressed patients and sixteen healthy controls were presented with a set of emotional facial expressions and were asked to identify the emotion portrayed by each face. They were subsequently given a recognition memory test for these faces. There was no difference between the groups in terms of their ability to identify emotion from faces. All participants identified emotional expressions more accurately than neutral expressions, with happy expressions being identified most accurately. During the recognition memory phase the depressed patients demonstrated superior memory for sad expressions, and inferior memory for happy expressions, relative to neutral expressions. Conversely, the controls demonstrated superior memory for happy expressions, and inferior memory for sad expressions, relative to neutral expressions. These results are discussed in terms of the cognitive model of depression proposed by Williams, Watts, MacLeod, and Mathews (1997).
