Correlates of retrospective early life experience with personality in young Japanese women

To examine the influence of early experiences on the development of personality. We used the Temperament and Character Inventory to assess 98 young women who had first entered a company. Different early experiences were linked, albeit weakly, to test scores. Both partial correlations and multiple regression analyses indicated that Self-directedness was higher if women reported more care of parents. Partial correlation, but not multiple regression analyses, showed that Cooperativeness was greater if women reported more care of parents and less frequent abuse. Reports of early parental loss or negative or positive early life events showed no correlation with scores on any of the Temperament and Character Inventory subscales.     

People with external preoccupation are vulnerable to depression: a longitudinal study

External preoccupation, the tendency to maintain an external focus of attention on a specific object, is believed to be a vulnerability factor for depression. The present study is an investigation of this hypothesis in a longitudinal design. At Time 1, external preoccupation as well as depressive symptoms were assessed. At Time 2, 4 months later, life events experienced between Time 1 and Time 2 and depressive symptoms at Time 2 were assessed. Data from 195 undergraduates (147 men and 48 women) were analyzed. The results supported the hypothesis. Specifically, when reporting a greater number of negative life events, those who scored high on external preoccupation became more depressed than those who scored low on that tendency. When there was a smaller number of negative events, this difference disappeared.     

The effectiveness of a skills‐based program in reducing public speaking anxiety

Research was conducted to test the effectiveness of a skills‐based program as a method for reducing anxiety during public speaking. Twenty‐five Japanese college sophomores were exposed to a systematic approach for developing a presentation that was theoretically linked to mechanisms to reduce communication apprehension (CA). Students gave four presentations that were graded by both teacher and peer evaluation. Results indicated that the experimental group reported a significantly greater drop in public speaking anxiety than did a control group of 86 students.     

The Impact of Authoritative, Authoritarian, and Permissive Parenting Styles on Children’s Later Mental Health in Japan: Focusing on Parent and Child Gender

Few studies in Japan have examined whether children’s later mental health is influenced by the way parental authority is exercised, specifically with a focus on gender. Our main purposes of this study were to confirm the three-factor structure of the Japanese version of the Parental Authority Questionnaire (PAQ) and to verify its reliability and validity. We then used structural equation modeling to examine whether children’s later mental health was influenced by parents’ authoritative, permissive, and authoritarian parenting. The subcategories included in the Japanese version of the Clinical Outcomes in Routine Evaluation-Outcome Measure were chosen as mental health indices. A total of 1,320 people in Japan, including company employees, university students, and hospital staff members, were asked to recall and evaluate the parenting they received and to report on their current mental health. Confirmatory factor analyses verified the three-factor structure of the Japanese version of the PAQ, with a reduction in the number of items from the original version. The respondents, regardless of gender, evaluated their mothers as having been more authoritative than their fathers. Concerning the impact of parenting styles on respondents’ later mental health, both maternal and paternal authoritarian parenting styles worsened respondents’ later mental health, including symptomatic problems, risk to self and others, life functioning, and psychological well-being. Both maternal and paternal authoritative parenting had a beneficial impact on respondents’ later mental health. Simultaneous analyses of multi-groups demonstrated that the nature of these influences did not vary with respondent gender. We present the above results in detail, and discuss them from psycho-socio-cultural viewpoints.     

Use of win-stay and win-shift strategies in place and cue tasks by medial caudate putamen (MCPu) lesioned rats

This study investigated the behavioral function of the medial caudate putamen (MCPu) in the solving of maze tasks. MCPu lesioned rats (n = 35) and control rats (n = 35) were trained for the place or cue task (the four baited arms and four unbaited arms task) in an eight-arm radial maze, which requires the win-stay or the win-shift strategy. In Experiment 1, in which the place task was used, MCPu lesioned rats could learn the task in the win-shift condition, but not in the win-stay condition. MCPu lesioned rats made a lot of unbaited errors in the win-stay condition, as they persistently chose adjacent arms. Control rats could learn the tasks in both conditions. In Experiment 2, in which the cue task was used, MCPu lesioned rats and control rats could learn the tasks in both the win-stay and the win-shift conditions. If anything, the performance of MCPu rats was a little better than that of control rats in the win-stay condition. The results of these two experiments revealed that the MCPu was involved in solving the win-stay place task, but not the win-shift place, win-stay cue, and win-shift cue tasks. These findings suggest that the MCPu plays an important role in utilizing both spatial information and switching foraging strategies flexibly and efficiently, that is, processing complicated visuospatial cognition.     

The relationship between nonverbal immediacy, student motivation, and perceived cognitive learning among Japanese college students

Research in the United States has found a strong and consistent relationship between teacher behavior and learning. Data collected from American college students indicate that perceptions of teacher nonverbal immediacy (NVI) are associated with students' feelings toward learning and perceptions of cognitive learning. The purposes of this study were to accomplish the following: (1) develop standardized Japanese versions of the instruments used to measure teacher nonverbal immediacy, student motivation, and perceived cognitive learning (how much students think they have learned); and (2) assess the relationship between NVI, student motivation, and perceptions of cognitive learning among Japanese college students. Results note that Japanese students report (1) a positive relationship between reported levels of teacher NVI and student motivation; (2) a negative relationship between reported levels of teacher NVI and perceived learning loss; and (3) a negative relationship between student motivation (SM) and perceived learning loss (how much students think they did not learn with their teacher compared to an ideal teacher). Further, cross-cultural comparisons between Japanese and American students were conducted. Results from the cross-cultural comparison suggest that the relationships between reported teacher nonverbal immediacy, student motivation, and learning loss among Japanese college students are similar to those found among American college students, but the dimensional structure of the questionnaires was different.     

Computational models of inductive reasoning using a statistical analysis of a Japanese corpus

Existing computational models of human inductive reasoning have been constructed based on psychological evaluations concerning the similarities or relationships between entities. However, the costs involved in collecting psychological evaluations for the sheer number of entities that exist mean that they are prohibitively impractical. In order to avoid this problem, the present article examines three types of models: a category-based neural network model, a category-based Bayesian model, and a feature-based neural network model. These models utilize the results of a statistical analysis of a Japanese corpus computing co-occurrence probabilities for word pairs, rather than using psychological evaluations. Argument strength ratings collected by a psychological experiment were found to correlate well with simulations for the category-based neural network model.     

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.     

A Pilot Study Addressing the Impact of Religious Practice on Quality of Life of Breast Cancer Patients During Chemotherapy

The aim of this preliminary study was to investigate whether religious practice can modify quality of life (QoL) in BC patients during chemotherapy. QoL and religion practice questionnaire (RPQ) scores were evaluated in a sample of BC patients in different moments. Before chemotherapy initiation, women with lower physical and social functional scores displayed higher RPQ scores. On the other hand, low RPQ patients worsened some QoL scores over time. Body image acceptance was positively correlated with religious practice and specifically praying activity. This preliminary study suggests the importance of religion in coping with cancer chemotherapy.
