Depression is associated with attentional biases for emotional information that are proposed to reflect stable vulnerability factors for the development and recurrence of depression. A key question for researchers is whether those who have recovered from depression also exhibit attentional biases, and if so, how similar these biases are to those who are currently depressed. To address this question, the present study examined attention to emotional faces in remitted depressed (N=26), currently depressed (N=16), and never depressed (N=33) individuals. Participants viewed sets of four face images (happy, sad, threatening, and neutral) while their eye movements were tracked throughout an 8-s presentation. Like currently depressed participants, remitted depressed participants attended to sad faces significantly more than never depressed participants and attended to happy faces significantly less. Analyzing temporal changes in attention revealed that currently and remitted depressed participants did not reduce their attention to sad faces over the 8-s presentation, unlike never depressed participants. In contrast, remitted depressed participants attended to happy faces similarly to never depressed participants, increasing their attention to happy faces over the 8-s presentation. The implications for cognitive theories of depression and depression vulnerability are discussed.
抑郁与对情绪信息的注意力偏差有关,这些偏差被认为反映了抑郁发生和复发的稳定脆弱性因素。研究人员的一个关键问题是,那些已经从抑郁中恢复的人是否也表现出注意力偏差,如果是,这些偏差与当前抑郁的人有多相似。为了解决这个问题,本研究检查了恢复期抑郁(N=26)、当前抑郁(N=16)和从未抑郁(N=33)个体对情绪面孔的注意力。参与者在 8 秒的呈现过程中观看了四组面部图像(快乐、悲伤、威胁和中性),同时跟踪他们的眼球运动。与当前抑郁的参与者一样,恢复期抑郁的参与者明显比从未抑郁的参与者更关注悲伤的面孔,而明显较少关注快乐的面孔。分析注意力的时间变化表明,当前和恢复期抑郁的参与者并没有像从未抑郁的参与者那样,在 8 秒的呈现过程中减少对悲伤面孔的注意力。相比之下,恢复期抑郁的参与者与从未抑郁的参与者一样关注快乐的面孔,随着 8 秒的呈现,他们对快乐的面孔的注意力增加。讨论了这些发现对抑郁的认知理论和抑郁易感性的意义。
