Attention and interpretation biases are closely involved in depression. However, it is unclear whether they reflect processing tendencies (i.e., driven by schemas) and/or ability-related processes (i.e., dependent on attentional control). This study tested depressive symptom severity, attention bias, and interpretation bias associations under both processing conditions. Fifty-two participants completed two versions of the scrambled sentences test (to measure interpretation bias) while eye movements were recorded (to measure attention bias). Participants were instructed to unscramble sentences by reporting the first sentence coming to mind (tendency version) and in a fixed, positive manner (ability version). Depressive symptom severity was correlated with attention bias under both conditions. Attention bias acted as an intervening variable in the relation between depressive symptoms and interpretation bias during ability processes. These findings suggest that attention biases reflect both processing tendencies and ability dysfunctions, with attentional control as a relevant mechanism in the interpretation of emotional material.
注意力和解释偏差与抑郁症密切相关。然而,尚不清楚它们是反映加工倾向(即由图式驱动)和/或与能力相关的过程(即依赖于注意力控制)。本研究在两种加工条件下测试了抑郁症状严重程度、注意力偏差和解释偏差之间的关联。52名参与者完成了两个版本的乱序句子测试(以测量解释偏差),同时记录眼动(以测量注意力偏差)。参与者被要求通过说出脑海中出现的第一个句子(倾向版本)和以固定的积极方式(能力版本)来解乱句子。在两种条件下,抑郁症状严重程度均与注意力偏差相关。在能力过程中,注意力偏差在抑郁症状与解释偏差的关系中起中介变量的作用。这些发现表明,注意力偏差既反映加工倾向,也反映能力功能障碍,注意力控制是解释情感材料的相关机制。
