Attentional biases are a relatively robust phenomenon among clinical populations but less pronounced in healthy participants. However, regarding the components of attentional biases and the directions of attention allocation, there are several inconsistencies in the literature. The present study examined whether these inconsistencies can be traced back to previous experiences of relational peer victimization in clinical populations.
Participants were subjects with a diagnosed psychiatric disorder (n = 30) and healthy controls (n = 31). Additionally, the sample was divided into two subgroups according to the participants' reports of previous relational peer victimization (high peer victimization: n = 28; low peer victimization: n = 33). Attentional biases were measured by the Emotional Stroop task and a dot-probe task.
In both samples, peer victimized participants showed delayed response times when color-naming negative and positive compared to neutral adjectives in the Emotional Stroop task. Likewise, the dot-probe task indicated attentional avoidance of both negative and positive words in peer victimized participants with and without a psychiatric disorder. Interestingly, presence of a psychiatric disorder did not have a significant effect on attentional biases.
Both tasks could detect that attentional processes were linked to the experience of peer victimization rather than to the current diagnostic status of the participants. Attentional avoidance of emotional stimuli may prevent victimized individuals from responding adequately to environmental stimuli, which may increase the risk for the development of psychopathology.
在临床人群中,注意偏差是一种相对稳定的现象,但在健康参与者中则不那么明显。然而,关于注意偏差的组成部分和注意分配的方向,文献中存在一些不一致的地方。本研究探讨了这些不一致是否可以追溯到临床人群中以前的关系性同伴侵害经历。
参与者为诊断为精神障碍的患者(n=30)和健康对照组(n=31)。此外,根据参与者以前是否有过关系性同伴侵害经历(高同伴侵害:n=28;低同伴侵害:n=33),将样本分为两个亚组。通过情绪斯特鲁普任务和点探测任务来测量注意偏差。
在两个样本中,被同伴侵害的参与者在情绪斯特鲁普任务中对颜色命名的负面和积极形容词的反应时间比中性形容词要慢。同样,点探测任务表明,无论是有精神障碍还是没有精神障碍的被同伴侵害的参与者,都会对负面和正面的单词表现出注意力回避。有趣的是,精神障碍的存在对注意偏差没有显著影响。
这两个任务都可以检测到,注意过程与同伴侵害的经历有关,而与参与者当前的诊断状态无关。对情绪刺激的注意力回避可能使受侵害的个体无法对环境刺激做出适当的反应,这可能会增加患精神病理学的风险。
