Previous research has suggested that worry is negatively associated with working memory performance. However, it is unclear whether these findings would replicate across different worry levels and in individuals with anxiety and depressive disorders (i.e. clinical statuses). One-hundred-thirty-eight participants performed a two-block working memory task (150 trials per block). Based on participants` current clinical status, four groups were considered (generalised anxiety disorder group: n = 36; clinical group with another anxiety or mood disorders: n = 33; subclinical group: n = 27; control group: n = 42). Trait worry levels were collected from all of the participants. Working memory performance was measured as accuracy and reaction time. During the first block, higher worry scores were significantly associated with longer reaction times. Moreover, the generalised anxiety disorder group, clinical group, and subclinical groups demonstrated significantly longer reaction times compared to the control group in Block 1, when age was controlled for. From Block 1 to Block 2, all of the participants demonstrated a significant decrease in accuracy and reaction time, regardless of worry level or clinical status. The results indicate that higher worry levels negatively impact WM processing efficiency. Moreover, when age was controlled for, we found participants` clinical status to be linked with WM impairments. The results highlight the relevance of investigating the impact of different worry levels on cognitive processes across clinical and non-clinical populations.

忧虑和临床状况如何影响工作记忆性能?实验研究。

先前的研究表明,担心与工作记忆性能负相关。但是,目前尚不清楚这些发现是否会在不同的忧虑程度以及患有焦虑和抑郁症(即临床状况)的个体中重复出现。一百三十八名参与者执行了两段式工作记忆任务(每段150次试验)。根据参与者当前的临床状况,将其分为四组(一般性焦虑症组:n = 36;患有另一种焦虑或情绪障碍的临床组:n = 33;亚临床组:n = 27;对照组:n = 42)。从所有参与者那里收集特质担忧水平。测量工作记忆性能作为准确性和反应时间。在第一个阶段中,较高的忧虑评分与较长的反应时间显着相关。而且,在控制年龄的情况下,广泛性焦虑症组,临床组和亚临床组的反应时间明显长于Block 1中的对照组。从第1块到第2块,所有参与者均显示出准确性和反应时间显着减少,无论担心水平或临床状况如何。结果表明,更高的担忧级别会对WM处理效率产生负面影响。此外,当控制年龄时,我们发现参与者的临床状况与WM障碍有关。结果突出了研究临床和非临床人群不同忧虑程度对认知过程的影响的相关性。与亚临床组相比,在控制年龄的情况下,与对照组1相比,反应时间明显更长。从第1块到第2块,所有参与者均显示出准确性和反应时间显着下降,无论担心水平或临床状况如何。结果表明,更高的担忧级别会对WM处理效率产生负面影响。此外,当控制年龄时,我们发现参与者的临床状况与WM障碍有关。结果突出了研究临床和非临床人群不同忧虑程度对认知过程的影响的相关性。与亚临床组相比,在控制年龄的情况下,与对照组1相比,反应时间明显更长。从第1块到第2块,所有参与者均显示出准确性和反应时间显着下降,无论担心水平或临床状况如何。结果表明,更高的担忧级别会对WM处理效率产生负面影响。此外,当控制年龄时,我们发现参与者的临床状况与WM障碍有关。结果突出了研究临床和非临床人群不同忧虑程度对认知过程的影响的相关性。无论忧虑程度或临床状况如何。结果表明,更高的担忧级别会对WM处理效率产生负面影响。此外,当控制年龄时,我们发现参与者的临床状况与WM障碍有关。结果突出了研究临床和非临床人群不同忧虑程度对认知过程的影响的相关性。无论忧虑程度或临床状况如何。结果表明,更高的担忧级别会对WM处理效率产生负面影响。此外,当控制年龄时,我们发现参与者的临床状况与WM障碍有关。结果突出了研究临床和非临床人群不同忧虑程度对认知过程的影响的相关性。
