Introduction
My primary research interests lie in the field of vulnerability and maintenance factors of depression, especially depressive rumination. My current works are focused on 1) development and validation of rumination measures, 2) investigation about how rumination interacts with other cognitive behavioral factors, and emotional and somatic states, and 3) specifying which factors prolongs rumination.

University students in five Japanese universities completed the Japanese version of the Beck Depression In...
Article
Full-text available
Previous research on relationships between self-reported impulsivity and behavioral impulsivity has been limited because behavioral impulsivity was assessed using individual tasks. To alleviate the task-impurity problem and the low reliability of laboratory tasks assessing impulsivity, the present study examined the correlations between a latent va...
Article
Full-text available
Background In the past, different stress generation studies have used self-report measures comprising different items to assess each category of negative events. Moreover, the validity of these scales has not been adequately investigated. Therefore, we developed a self-report measure dedicated to assessing experiences of negative interpersonal depe...
Article
Full-text available
The relationship between trait rumination and working memory has not been well established. Previous studies have shown that high ruminators have poor working memory in general, while others have shown that they have superior working memory ability. Therefore, we tested the hypothesis that high ruminators have an imbalanced working memory ability,...
Article
Full-text available
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 re...

The affinity for hikikomori represents the desire to be withdrawn, as well as to entertain an empathetic attitude towards withdrawn individuals. It is composed of two subdimensions, the maladaptive desire for hikikomori, and empathy for others with hikikomori. This longitudinal study examined whether autistic traits predicted the affinity for hikik...

Full-text available
Young, Sutherland, and McCoy indicated that a Go/No-Go Task (GNG) becomes more difficult as the inter-stimulus intervals (ISIs) becomes shorter. However, is the number of commission errors under extremely short ISIs a useful metric for assessing response inhibition? This study challenges the assumption that a shorter ISI in the GNG enables better a...

Undergraduate students (N=363) completed the Empathic-Affective Response Scale, and measures of affect, prosocial behaviors, and aggressive behaviors. Confirmatory factor analyses, based on the item composition of Sakurai et al. (2011), indicated that empathic affective responses toward the positive affect of others cannot be divided between sharin...
Article
Recent studies have suggested that the affinity for hikikomori might be a precursor of "hikikomori" (which is a type of social withdrawal seen in Japan). Moreover, late adolescents and young adults including undergraduates had higher scores of the affinity for hikikomori. The present study examined how coping strategies and help-seeking behaviors i...
