The current study directly examined emotion-induced behavior dyscontrol among individuals scoring high on dysregulated tendencies, represented by impulsive-antisocial and borderline personality traits, using an emotional-linguistic go/no-go laboratory paradigm (Goldstein et al., 2007). We specifically examined the effects of these personality traits and emotional context on (a) overall behavior dyscontrol (slower reaction times [RTs] to emotional blocks relative to neutral blocks) and (b) duration of the dyscontrol (persistence or habituation of the effect of emotional context on behavior across blocks). We hypothesized that individuals high on borderline-antisocial traits would exhibit greater behavioral dyscontrol (slower RTs or lack of habituation across blocks) when responding during blocks of negative emotional cues. We also examined whether this emotional effect on behavioral control would be exacerbated by exposure to particularly salient emotional stimuli (diagnostically relevant negative affective words; e.g., abandon). Results indicated that high borderline-antisocial individuals showed greater initial behavioral control difficulties (slower RTs) to general negative affective words than to other word contents during the first block of trials, but this effect habituated by the second block. Importantly, slowed responses to diagnostically relevant word blocks persisted across time among high borderline-antisocial individuals, whereas low scorers showed habituated behavioral responses to emotional words across time.
本研究采用情绪语言 Go/No-Go 实验室范式(Goldstein 等人,2007),直接考察了冲动反社会和边缘型人格特质等失调倾向得分较高的个体的情绪诱导行为失控情况。我们特别考察了这些人格特质和情绪背景对(a)整体行为失控(相对于中性刺激,情绪刺激的反应时较慢)和(b)失控持续时间(情绪背景对行为的影响在各刺激块间的持续或习惯化)的影响。我们假设,在负性情绪线索刺激块中做出反应时,高边缘-反社会特质个体的行为失控会更加明显(反应时较慢或各刺激块间无习惯化)。我们还考察了情绪对行为控制的影响是否会因暴露于特别显著的情绪刺激(诊断相关的负性情感词,如抛弃)而加剧。结果表明,高边缘-反社会个体在第一个试次块中,对一般负性情感词的初始行为控制困难(反应时较慢)大于其他词类,但这种效应在第二个试次块中习惯化。重要的是,高边缘-反社会个体对诊断相关词块的反应速度在整个测试过程中持续减慢,而低得分个体对情绪词的行为反应在整个测试过程中逐渐习惯化。
