“…For example, some studies that utilised larger sample sizes and many executive function tasks did not show the association between superior performance and trait-rumination for the Stroop task (e.g. Nishimura et al, 2020). Unlike these studies, the current study paid particular attention to attentional control and removal processing.…”

“…Joormann & Gotlib, 2008;Zetsche et al, 2018). On the other hand, undergraduate students with high traitrumination and mild depressive symptoms were not necessarily characterized by deficits of working memory (Altamirano et al, 2010;Nishimura et al, 2020;Onraedt & Koster, 2014). To understand the association between the working memory and traitrumination in nonclinical undergraduate students, we focused on two different working memory functioning: attentional control and removal speed.…”

Higher trait-rumination is associated with several psychopathologies. Previous studies showed that an impaired working memory in depressed patients was associated with higher trait-rumination. Meanwhile, in the nonclinical undergraduate population, a few studies reported the association between superior working memory and trait-rumination. To clarify the association between trait-rumination and the individual differences in working memory, we utilised two conceptually different working memory functions: attentional control and removal speed. Attentional control is involved in continuing to focus on goal-relevant information while blocking goal-irrelevant information and is reflected by working memory capacity. Removal speed is the time required to quickly remove goal-irrelevant information from working memory. Ninety-five undergraduate students took the reading span test and the working-memory-updating task to measure these functions. Results showed that increased trait-rumination was correlated to superior performance in the attentional control as well as the removal speed after controlling depressive symptoms. The current findings suggest that higher trait-rumination in undergraduate students is characterized by superior working memory, which contrasts with prior findings of people with depression. Further studies should examine the roles of superior working memory from the viewpoint of the developmental processes of rumination.

“…Inconsistent with the study by Altamirano et al (2010), the current study indicated that attentional inhibition deficits were unrelated to trait rumination. A nonsignificant association between attentional inhibition deficits and trait rumination was also reported in Nishimura et al (2020). Therefore, it is implausible that high ruminators could better resist interference from distracting stimuli.…”

“…They interpreted this result as reflecting higher active maintenance of a single task goal by trait ruminators in the face of distractions. The findings by Altamirano et al ( 2010 ) contradict the assumption that high ruminators have inhibition impairments, although caution is needed because a subsequent study found no significant correlation between trait rumination and MST performance (Nishimura et al, 2020 ).…”

“…For example, although Hasegawa et al ( 2021 ) showed that a latent variable that reflected response inhibition deficits was indirectly associated with increased trait rumination via increased stressors, they did not examine the behaviors that mediated the association between response inhibition and stressors. Moreover, previous studies have not examined the possible mediators in the association between attentional inhibition and rumination (Altamirano et al, 2010 ; Nishimura et al, 2020 ).…”

Previous findings on relationships between inhibition that is a core executive function, and trait rumination have been inconsistent. This inconsistency could be overcome by investigating the association between rumination and the two subcomponents of inhibition: response inhibition and attentional inhibition. This study examined whether and how response inhibition and attentional inhibition were related to rumination as well as worry. University students in Japan (N = 213) conducted the Go/No-Go Task and the Modified Stroop Task. They also completed self-report measures of depression, trait rumination, trait worry, stressors, and aggressive behaviors. Results indicated that response inhibition deficits were positively associated with trait rumination, and this association was mediated by increases in aggressive behaviors and interpersonal stressors. The associations between these variables remained significant even after controlling for depression level. There were no significant direct or indirect associations between attentional inhibition deficits and rumination. These results suggest that response inhibition deficits, among the subcomponents of inhibition, have an indirect positive association with rumination through interpersonal processes. Results also showed nonsignificant differences between rumination and worry in the magnitude of correlation coefficients with the two subcomponents of inhibition. Therefore, it remains unclear whether the positive association with response inhibition is unique to rumination.
