Abstract

Inhibitory control, the ability to suppress or countermand an action or thought, is notably impaired in patients with bipolar disorder. However, the specific characteristics of this impairment and whether deficits can manifest prior to a formal bipolar disorder diagnosis or among individuals with subsyndromal symptoms are relatively unknown. Here we test whether healthy individuals exhibiting a higher level of hypomanic personality traits respond more rapidly, albeit with weaker inhibitory control. We evaluated 83 native French speakers using the Hypomanic Personality Scale (HPS) and administered the Hayling Sentence Completion Test for response inhibition and the Stroop Test for interference control. We found negative correlations between the HPS score and both the response initiation and response inhibition times on the Hayling Sentence Completion Test, but the scores did not affect accuracy. Regarding the Stroop Test, we observed a significant positive correlation between the scores for hypomanic personality traits and the number of errors on the color-word condition. Our findings demonstrate that a high level of hypomanic personality traits correlates with faster reaction times on response inhibition tasks and higher error rates on interference tasks. This underlines the importance of distinguishing between inhibitory control concepts when examining the risks of bipolar disorder.
“船长想待在下沉的船上……(不能说船)”:轻躁狂的人格特征是如何干扰抑制控制的?
抑制控制,即抑制或反对某种行为或想法的能力,在躁郁症患者中明显受损。然而,这种损伤的具体特征,以及这种缺陷是否会在双相情感障碍正式诊断之前或在具有亚综合征症状的个体中表现出来,这些都是相对未知的。在此,我们测试了表现出较高程度躁狂症人格特征的健康人是否反应更快,尽管抑制控制能力较弱。我们使用躁狂症人格量表(HPS)对 83 名母语为法语的人进行了评估,并使用海林句子完成测试(Hayling Sentence Completion Test)和斯特罗普测试(Stroop Test)来检测反应抑制和干扰控制能力。我们发现,在海林句子完成测试中,HPS 分数与反应启动时间和反应抑制时间之间存在负相关,但分数并不影响准确性。在斯特罗普测验中,我们观察到躁狂症人格特质得分与颜色词条件下的错误次数之间存在显著的正相关。我们的研究结果表明,高水平的躁狂症人格特质与反应抑制任务中更快的反应时间和干扰任务中更高的错误率相关。这强调了在研究躁郁症风险时区分抑制控制概念的重要性。

期刊介绍: Founded in 1961 to report on the latest work in psychiatry and cognate disciplines, the Journal of Psychiatric Research is dedicated to innovative and timely studies of four important areas of research: (1) clinical studies of all disciplines relating to psychiatric illness, as well as normal human behaviour, including biochemical, physiological, genetic, environmental, social, psychological and epidemiological factors; (2) basic studies pertaining to psychiatry in such fields as neuropsychopharmacology, neuroendocrinology, electrophysiology, genetics, experimental psychology and epidemiology; (3) the growing application of clinical laboratory techniques in psychiatry, including imagery and spectroscopy of the brain, molecular biology and computer sciences;
