鉴于先前的研究表明抑郁症患者对消极自我参照信息表现出优先加工，本研究调查了认知上易受抑郁症影响的人是否表现出类似的消极自我参照加工。在坦普尔-威斯康辛抑郁认知脆弱性项目中，非抑郁参与者根据其功能失调的态度和推理风格被假设为抑郁的认知风险高或低，他们被给予自我参照信息处理任务组，该任务组产生了五项信息处理测量：特征词的自我描述性判断（“我/不是我”）；这些判断的响应时间；自我描述词的过去行为例子；未来行为预测；对特征词的正确记忆。在效价x内容设计中，每一项依赖测量都产生了四种刺激类型的分数：与抑郁自我概念相关或不相关的积极和消极刺激。与预测一致，相对于低认知风险参与者，高认知风险参与者在所有测量中表现出更多的消极自我参照信息加工和更少的积极自我参照信息加工。此外，有一些证据表明，在抑郁相关的内容领域，自我参照加工偏差的风险组差异大于抑郁无关的内容领域。研究结果讨论了对抑郁症认知理论的理论和方法意义。
Whereas prior work has demonstrated that depressed persons exhibit preferential processing of negative self-referent information, the present study investigated whether persons who are cognitively vulnerable to depression show similar negative self-referent processing. Nondepressed participants in the Temple-Wisconsin Cognitive Vulnerability to Depression Project who were at hypothesised high or low cognitive risk for depression based on their dysfunctional attitudes and inferential styles were administered a Self-referent Information Processing Task Battery that yielded five information-processing measures: judgements of self-descriptiveness (''Me/Not Me'') of trait words; response times for these judgements; past behavioural examples for self-descriptive words; future behavioural predictions; and correct recall of the trait words. Each dependent measure yielded scores for four types of stimuli in a Valence x Content design: positive and negative stimuli that were either relevant or irrelevant to a depressive self-concept. Consistent with prediction, relative to low cognitive risk participants, high cognitive risk participants exhibited greater processing of negative seif-referent information and less processing of positive self-referent information on all measures. Moreover, there was some evidence that risk group differences in self-referent processing biases were greater for depression-relevant than for depression-irrelevant content domains. The findings are discussed with respect to theoretical and methodological implications for the cognitive theories of depression.
