This paper investigates whether changes in mood state are an important component of cognitive bias modification (CBM) procedures. In a novel CBM procedure participants read either positive or negative statements relating to social issues for 5 min. Interpretation bias was measured by means of a scrambled sentence test, which was presented both before and after the CBM procedure. Participants who read the positive statements made more positive resolutions to the scrambled sentences, while participants who read the negative statements made more negative resolutions. Thus, the appropriate positive and negative interpretative biases were induced by the CBM procedure. However, significant mood changes also occurred following CBM. In Experiment 2, a musical mood induction procedure was presented with depressing or elating music. As before, a scrambled sentence test was presented both before and after the musical mood induction. Mood changed in accordance with the valence of the music to the same extent as with CBM. Critically however, performance on the scrambled sentence task did not change for both groups. This demonstrates that a change in mood state is not sufficient for a change in cognitive bias to occur.
本文探讨了心境状态的变化是否是认知偏差修正（CBM）程序的一个重要组成部分。在一种新颖的 CBM 程序中，参与者阅读与社会问题相关的积极或消极陈述 5 分钟。通过打乱句子测试来测量解释偏差，该测试在 CBM 程序之前和之后呈现。阅读积极陈述的参与者对打乱的句子做出了更积极的解决方法，而阅读消极陈述的参与者则做出了更消极的解决方法。因此，适当的积极和消极解释偏差是由 CBM 程序引起的。然而，CBM 后也会发生显著的情绪变化。在实验 2 中，呈现了具有压抑或振奋作用的音乐的音乐情绪诱导程序。和之前一样，在音乐情绪诱导前后都呈现了打乱句子测试。情绪按照音乐的效价发生变化，与 CBM 的变化程度相同。然而，重要的是，两组在打乱句子任务上的表现都没有改变。这表明情绪状态的变化不足以导致认知偏差的改变。
