Intrusive emotional memories were induced by aversive auditory stimuli and modulated with cognitive tasks performed post-encoding (i.e., during consolidation).
A between-subjects design was used with four conditions; three consolidation-interference tasks (a visuospatial and two verbal interference tasks) and a no-task control condition. Forty-one participants listened to a soundtrack depicting traumatic scenes (e.g., police brutality, torture and rape). Immediately after listening to the soundtrack, the subjects completed a randomly assigned task for 10 min. Intrusions from the soundtrack were reported in a diary during the following seven-day period.
In line with a modality-specific approach to intrusion modulation, auditory intrusions were reduced by verbal tasks compared to both a no-task and a visuospatial interference task..
The study did not control for individual differences in imagery ability which may be a feature in intrusion development.
The results provide an increased understanding of how intrusive mental images can be modulated which may have implications for preventive treatment..
厌恶听觉刺激诱发侵入性情绪记忆，并通过编码后（即巩固过程中）执行的认知任务进行调节。
采用被试间设计，包含四种条件；三种巩固干扰任务（一项视觉空间任务和两项言语干扰任务）以及一个无任务对照条件。41名参与者聆听了一段描绘创伤场景（如警察暴行、酷刑和强奸）的音轨。听完音轨后，受试者立即随机完成一项任务，持续10分钟。在接下来的七天里，受试者需在日记中记录来自音轨的侵入情况。
与特定模态的侵入调节方法一致，与无任务和视觉空间干扰任务相比，言语任务减少了听觉侵入。
该研究未控制意象能力的个体差异，而意象能力可能是侵入发展的一个特征。
这些结果增进了我们对如何调节侵入性心理意象的理解，这可能对预防性治疗有启示意义。
