使用图片-文字线索的实验证据表明，产生心理意象对情绪有因果影响，至少对于由消极或良性刺激引起的图像。目前尚不清楚这一发现是否延伸到公开的积极刺激，以及产生积极的意象是否可以增加焦虑症患者的积极影响。焦虑的参与者被分配到三个条件之一，并给出指示，以产生心理图像，以响应图片-文字线索，这些线索是积极的，消极的或混合（控制）的效价。结果表明，积极的图片-文字条件比对照和消极条件更能增加被试的积极情感。与其他两种情况相比，积极条件下的参与者在行为任务上的表现也有所增强。与消极条件下的参与者相比，积极条件下的参与者在24小时后执行的同音字任务上提供了更积极的反应，以评估效果的持久性。这些研究结果表明，一个积极的图片-文字任务，用于唤起心理意象，导致积极情绪的改善，转移到以后的表现。了解烦躁不安情绪变化的潜在机制可能对理论和治疗发展都有影响。一个心理意象生成任务进行了测试的样本焦虑的参与者。►我们检查了抑郁情绪、行为和认知偏见的变化。⑶比较正、负和混合效价（对照）表象条件。积极的形象导致情绪和行为的改善。
Experimental evidence using picture–word cues has shown that generating mental imagery has a causal impact on emotion, at least for images prompted by negative or benign stimuli. It remains unclear whether this finding extends to overtly positive stimuli and whether generating positive imagery can increase positive affect in people with dysphoria. Dysphoric participants were assigned to one of three conditions, and given instructions to generate mental images in response to picture–word cues which were either positive, negative or mixed (control) in valence. Results showed that the positive picture–word condition increased positive affect more than the control and negative conditions. Participants in the positive condition also demonstrated enhanced performance on a behavioural task compared to the two other conditions. Compared to participants in the negative condition, participants in the positive condition provided more positive responses on a homophone task administered after 24 h to assess the durability of effects. These findings suggest that a positive picture–word task used to evoke mental imagery leads to improvements in positive mood, with transfer to later performance. Understanding the mechanisms underlying mood change in dysphoria may hold implications for both theory and treatment development. ► A mental imagery generation task was tested on a sample of dysphoric participants. ► We examined changes in depressed mood, behaviour and cognitive bias. ► Positive, negative and mixed valence (control) imagery conditions were contrasted. ► Positive imagery led to an improvement in mood and behaviour.
