IntroductionPrevious studies on metacognitive ability were explored using self-report questionnaires that are difficult to adequately measure and evaluate when the capacity for self-reference is undeveloped. This study aimed to validate the Congruency-based Metacognition Scale to measure metacognition and the feeling of confidence abilities and to investigate the development of metacognition during adolescence.MethodsThe CMS was administered to 633 child–parent pairs in Japan. The CMS metacognition score was assessed based on congruency scores between the self-report of the child from a third-person perspective (...) and the parent’s report from the first-person perspective. The CMS self-judgment accuracy score was assessed by the congruency scores between the children’s self-report from the 1PP and 3PP. For both measures, the more distant the 3PP on the self-report was from the 1PP on the parent’s report and child self-report means low ability. An exploratory factor analysis was conducted to examine construct validity and then a confirmatory factor analysis was used. Criterion validity was examined by calculating Pearson’s correlation coefficients with scores on the Beck Cognitive Insight Scale and Autism Quotient. We used intraclass correlation and Cronbach’s alpha to examine the test–retest and internal consistency reliability.ResultsBased on the results of the EFA and CFA, we adopted one factor structure with five items. The CMS metacognition and CMS self-judgment accuracy showed evidence criterion validity, exhibiting significant correlations with the BCIS self-reflectiveness and self-certainty scores, respectively. Regarding to the AQ, only the CMS metacognition score had significant correlations with the social skills and total scale score. The test–retest reliability showed adequate. Adolescents were found to have significantly lower metacognitive ability compared to young adults.ConclusionCMS could be a valid and reliable measure to examine metacognitive abilities for adolescents.

Site‐specific phosphorylation of intermediate filament (IF) proteins on serine and threonine residues leads to alteration of the filament structure, in vitro and in vivo. Protein kinases involved in cell signaling and those activated in mitosis dynamically control spatial and temporal organization of intracellular IF phosphorylation. Thus, IF phosphorylation appears to be one of the most predominant strategies in coordinating intracellular organization of the IF network.

Background: An external locus of control is associated with poorer psychopathology in individualist cultures, but associations are reported to be weaker in collectivist cultures where an external style is less maladaptive. We investigated the prospective association between externality and psychotic-like experiences and depressive symptoms and compared the strength of associations between a UK and a Japanese cohort.Method: Cross-cultural cohort study of a UK and a Japanese cohort. Externality was assessed using the Children's Nowicki and Strickland Internal, External Scale and DS (...) using the Short Moods and Feelings Questionnaire in both cohorts, PLE were assessed with the Psychosis-Like Experiences Questionnaire, and the Adolescent Psychotic-Like Symptom Screener. Associations were investigated using multivariable regression models and bivariate regression models to compare the strength of associations.Results: Mean externality in both childhood and adolescence was higher in ALSPAC than in the TTC. Childhood externality was associated with PLE in late childhood and adolescence in both cohorts and adolescent externality was associated with PLE in young adulthood in the ALSPAC cohort. There was a more mixed pattern of association between externality and DS scores. There was little evidence of any differences in the strength of associations between externality and different psychopathologies, or between cohorts. In ALSPAC adolescent externality and early adult psychopathology were more strongly associated than childhood externality and adolescent and early adult psychopathology. There was no evidence that change in externality between childhood and adolescence was associated with new onset PLE or DS in early adulthood.Conclusion: An external locus of control is associated with poor mental health regardless of cultural context.

To further develop three-dimensional (3D) applications, it is important to elucidate the negative effects of 3D applications on the human body and mind. Thus, this study investigated differences in the effects of visual fatigue on cognition and brain activity using visual and auditory tasks induced by watching a 1-h movie in two dimensions (2D) and 3D. Eighteen young men participated in this study. Two conditions were randomly performed for each participant on different days, namely, watching the 1-h movie on television (...) in 2D (control condition) and 3D (3D condition). Before and after watching the 1-h movie on television, critical flicker fusion frequency (CFF: an index of visual fatigue), and response accuracy and reaction time for the cognitive tasks were determined. Brain activity during the cognitive tasks was evaluated using a multi-channel near-infrared spectroscopy system. In contrast to the control condition, the decreased CFF, and the lengthened reaction time and the decreased activity around the right primary somatosensory cortex during Go/NoGo blocks in the visual task at post-viewing in the 3D condition were significant, with significant repeated measures correlations among them. Meanwhile, in the auditory task, the changes in cognitive performance and brain activity during the Go/NoGo blocks were not significant in the 3D condition. These results suggest that the failure or delay in the transmission of visual information to the primary somatosensory cortex due to visual fatigue induced by watching a 3D movie reduced the brain activity around the primary somatosensory cortex, resulting in poor cognitive performance for the visual task. This suggests that performing tasks that require visual information, such as running in the dark or driving a car, immediately after using a 3D application, may create unexpected risks in our lives. Thus, the findings of this study will help outlining precautions for the use of 3D applications. (shrink)

This work comprises the works of Shoeki translated in full. When Ando Shoeki's writings were discovered nearly a century ago, they were thought to be forgeries, such was their uniqueness and revolutionary nature. But his sharp and thoughful criticism of the Japanese feudal order proved to be genuine. Shoeki's philosophy combines and criticizes Buddhism, Confucianism and traditional Oriental medical theories offering a unique view of humanity, society and the natural world that is startling in its modernity. He advocates ecology, equality (...) of the sexes and the abolition of the feudal order. His writings combine Swiftian parable, Platonic dialogue and philosophical treatise, and is an important key to understanding the history of Japanese thought. (shrink)
