Relationship of sports experience and ego development of adolescent Japanese athletes

This study examined the relationship of sports experience with ego development. A questionnaire was used to assess experience of Crisis, Exploration, and Commitment in the issues of Athletic Performance and of Being a Teammate in 782 adolescent Japanese athletes (423 boys, M age = 15.2 yr.; 359 girls, M age = 15.0 yr.). Their Ego Levels were assessed using the Washington University Sentence Completion Test. Correlations indicated that scores on Crisis, Exploration, and Commitment in the issues of Athletic Performance and Being a Teammate were generally associated with Ego Development. Multiple regression analyses indicated that, for boys, the issue of Athletic Performance was closely associated with Ego Development, while for girls, the issue of Being a Teammate was closely associated with Ego Development. Sports experience with crisis, exploration, and commitment may be related to accommodation, which is, in turn, related to ego development. The sex differences on issues related to ego development may be associated with differences in sex-role development for boys and girls.     

The recognized benefits of negative thinking/affect in depression and anxiety: Developing a scale

Negative thinking/affect (NTA) in depression and anxiety is an important target of clinical intervention. However, individuals recognize the benefit of NTA. There is a need to develop a scale for empirical studies of NTA. Two‐hundred and fifty‐nine Japanese university students were assigned to answer: (a) the state in the past week (positive affect (PA) and Center for Epidemiologic Studies Depression Scale), (b) the current state (PA and State‐Trait Anxiety Inventory‐State (STAI‐S)), and (c) the usual state (PA and STAI‐Trait), after completing the Recognized Benefit of NTA Scale (RBNTA). Another 291 students completed the Rosenberg Self‐Esteem Scale and the Revised Life Orientation Test, after completing the RBNTA. Two weeks later, 76 participants completed the RBNTA. The RBNTA with nine subscales was developed after comparing the indices of fitness from 14 different factor solutions. The internal and test‐retest reliability and content validity were confirmed. Correlation analyses revealed that the recognition of trying to obtain benefits/avoid costs tends to associate with positive/negative affect and that most of such recognitions did not associate with self‐esteem and optimism.     

Individual neuropsychological profiles at age 5½ years in children born preterm in relation to medical risk factors

Follow-up studies of preterm children have reported a range of cognitive deficits, particularly in executive functions, visuospatial abilities, and learning. However, few researchers have adopted a person-oriented approach, exploring individual neuropsychological profiles. The aim of this study was to identify typical neuropsychological profiles among preterm children and control children, respectively. A second aim was to investigate if neuropsychological profiles at age 5½ might be associated with perinatal medical risk factors. As part of the longitudinal Stockholm Neonatal Project, NEPSY for 4- to 7-year-old children (Korkman, 1990 Korkman, M. 1990. NEPSY, Neuropsychological Assesment 4–7 years: Swedish Version, Stockholm, , Sweden: Psykologiförlaget AB.  [Google Scholar]), WPPSI-R, and Movement ABC were administered at age 5½ years to 145 preterm (mean gestational age 28 weeks) and 117 control children born at term. For the present study, the NEPSY results of each child were transformed into summary z scores for each of 5 neuropsychological domains: attention, memory, sensory-motor, verbal, and visuospatial functions. Subsequently, Ward's cluster analysis was performed for the preterm and control groups separately, identifying 5 neuropsychological profiles in both groups explaining around 56% and 57% of the variance, respectively. Overall, preterm children had lower neuropsychological results but also more diverging profiles compared to controls. The variability in outcome could not be sufficiently explained by birth weight, gestational age, or medical risks. The results suggest that prematurity interacts dynamically with genetic, medical, and environmental factors in neuropsychological development.     

Benefits of negative thinking and negative affect: analyses of answers to an open-ended question by Japanese undergraduates

What are the benefits of negative thinking and negative affect? Although previous studies in evolutionary psychology, social psychology, and clinical psychology have clarified the question, there has been no definitive study asking people directly about the perceived benefits. In the present study, 119 Japanese undergraduates were asked how they recognized the benefits of negative thinking and negative affect. Their answers were analyzed qualitatively. The answers were arranged into 30 smaller categories and 12 superordinate ones. The benefits were divided into "benefits to the self" and "benefits to interpersonal relations". Finally, the conditions necessary for the negative thinking and negative affect being benign, and possible cultural differences, were discussed.     

A longitudinal model of executive function development from birth through adolescence in children born very or extremely preterm

Executive function deficits are often reported as a specific weakness in preterm children. Yet, executive function development is still not fully understood. In a prospective longitudinal study, 115 preterm born children, ≤31 weeks of gestation, were recruited at birth and subject to neuropsychological assessments at ages 5.5 and 18 years. By applying Miyake and colleagues’ integrative framework of executive function to our data, two core components of executive function, working memory and cognitive flexibility, were identified through confirmatory factor analysis. Developmental stability was investigated in a serial multiple mediator structural equation model. Biological, medical, and social factors as well as mental development at 10 months were entered as predictors. Both components of executive function were highly stable from 5.5 to 18 years. Gestational age, intrauterine growth, lack of perinatal medical complications, and female sex were positively related to mental development at 10 months, which together with parental education influenced both core executive functions at 5.5 years. Working memory at 5.5 years mediated outcome in working memory at 18 years. In addition to the mediation of cognitive flexibility at 5.5 years, perinatal medical complications and restricted intrauterine growth had a continued direct negative impact on cognitive flexibility at 18 years. The application of a theoretical framework added to our understanding of executive function development in preterm born children. The study supports early identification of executive deficits among children born preterm, as deficits are unlikely to diminish with maturation.
