The directionality and functional organization of frontoparietal connectivity during consciousness and anesthesia in humans

Frontoparietal connectivity has been suggested to be important in conscious processing and its interruption is thought to be one mechanism of general anesthesia. Data in animals demonstrate that feedforward processing of information may persist during the anesthetized state, while feedback processing is inhibited. We investigated the directionality and functional organization of frontoparietal connectivity in 10 human subjects anesthetized with propofol on two separate occasions. Multichannel electroencephalography and a computational method of assessing directed functional connectivity were employed. We demonstrate that directed feedback connectivity is diminished with loss of consciousness and returns with responsiveness to verbal command. We also applied the Dendrogram classification method to assess the global organization of directed functional connectivity during consciousness and anesthesia. We demonstrate a state-specific hierarchy and subject-specific subhierarchy in functional organization. These data support the hypothesis that specific states of human consciousness are defined by specific states of frontoparietal connectivity.     

Ten-year-old girls' and boys' body composition and peer victimization experiences: prospective associations with body satisfaction

This study examined prospective associations between 10-year-olds’ weight and height, their perception of shape and stature, frequent experiences of peer victimization, and different aspects of body esteem at age 13. Participants were 474 girls and 400 boys participating in a two-wave longitudinal questionnaire study. Main results were that whereas actually being heavier built at age 10 was associated with girls’ increments in body dissatisfaction, the mere perception of being too heavy was associated with boys’ poorer body satisfaction. Also, boys who believed that they were too short were more dissatisfied at follow-up. Whereas frequent peer victimization had long-term associations with girls’ weight-esteem, teasing targeted towards appearance was associated with boys’ more negative beliefs about what others think about their appearance. Finally, participants had become significantly more dissatisfied at age 13, suggesting that this is a time in life when both girls and boys risk becoming increasingly critical towards their appearance.     

Two-Way Regularized Fuzzy Clustering of Multiple Correspondence Analysis

Multiple correspondence analysis (MCA) is a useful tool for investigating the interrelationships among dummy-coded categorical variables. MCA has been combined with clustering methods to examine whether there exist heterogeneous subclusters of a population, which exhibit cluster-level heterogeneity. These combined approaches aim to classify either observations only (one-way clustering of MCA) or both observations and variable categories (two-way clustering of MCA). The latter approach is favored because its solutions are easier to interpret by providing explicitly which subgroup of observations is associated with which subset of variable categories. Nonetheless, the two-way approach has been built on hard classification that assumes observations and/or variable categories to belong to only one cluster. To relax this assumption, we propose two-way fuzzy clustering of MCA. Specifically, we combine MCA with fuzzy k-means simultaneously to classify a subgroup of observations and a subset of variable categories into a common cluster, while allowing both observations and variable categories to belong partially to multiple clusters. Importantly, we adopt regularized fuzzy k-means, thereby enabling us to decide the degree of fuzziness in cluster memberships automatically. We evaluate the performance of the proposed approach through the analysis of simulated and real data, in comparison with existing two-way clustering approaches.     

Intellectual intuition and Kant's epistemology

In order to construct culture‐inclusive theories of psychology to establish an autonomous academic tradition of Confucian humanism, this article provides a commentary on Zongshan Mou's philosophy of intellectual intuition (智的直覺) as well as his systematic bias in translating Kant's epistemology of transcendental idealism (先驗理念論) into Chinese as ‘transcendent idealism’ (超越觀念論). I will demonstrate that his systematic bias in translating Kant's epistemology into Chinese may hinder his followers in developing a comprehensive understanding of the dialectical relationships among various paradigms of the Western philosophy of science, while his philosophy of intellectual intuition not only deviates from the original philosophical stance of pre‐Qin Confucians towards Heaven (天) and Dao (道), but also leads to his misunderstanding of Zhu Xi's philosophy and exploration of human nature (性), which may help us to understand the necessity of a psychodynamic model of cultural psychology with its emphasis on collective unconsciousness instead of the metaphor of Height Psychology.     

The psychotherapy adaptation and modification framework: application to Asian Americans

Although effective treatments for many mental disorders have been developed, little research has been conducted to determine whether these interventions are effective in treating those from diverse backgrounds. Recent reports have suggested that ethnic minorities are less likely to receive quality health services and that they evidence worse treatment outcomes when compared with other groups. To improve care for those from diverse backgrounds, Western-developed psychotherapies may need to be culturally modified or adapted to become more effective in treating ethnic minorities. This article addresses the need for adapting psychotherapy and provides a conceptual framework for making such modifications. The psychotherapy adaptation and modification framework model is applied to recent Asian American immigrants as an illustrative example. However, it may also serve as a point of departure to adapt therapies for other ethnocultural groups.     

A Japanese short form of the Swanson Cognitive Processing Test to measure working memory: reliability, validity, and differences in scores between primary school children of the United States and Japan

The purpose of this study was to examine the reliability and validity of a Japanese short form of the Swanson Cognitive Processing Test, which assesses capacity of working memory. Test-retest reliability was acceptable (r = .76). Concurrent validity was suggested through comparison of scores on the Reading Span Task (r = .55). Means on the Japanese short form were comparable with means for the 3 subtests for the older group and 2 subtests for the younger group. With the exception of the Auditory Digit Sequence, results suggested that both the Japanese short form and the initial Swanson Cognitive Processing Test measured comparably the working memory in the two samples of children.     

Advances in magnetic resonance imaging methods for the evaluation of bipolar disorder

This article reviews the current state of magnetic resonance imaging techniques as applied to bipolar disorder. Addressed are conventional methods of structural neuroimaging and recently developed techniques. This latter group comprises volumetric analysis, voxel-based morphometry, the assessment of T2 white matter hyperintensities, shape analysis, cortical surface-based analysis, and diffusion tensor imaging. Structural analysis methods used in magnetic resonance imaging develop exponentially, and now present opportunities to identify disease-specific neuroanatomic alterations. Greater acuity and complementarity in measuring these alterations has led to the generation of further hypotheses regarding the pathophysiology of bipolar disorder. Included in the summary of findings is consideration of a resulting neuroanatomic model. Integrative issues and future directions in this relatively young field, including multi-modal approaches enabling us to produce more comprehensive results, are discussed.     

A comparison of coping factors in Western and non-Western cultures

This study presents convergent support for the use of three empirically constructed factors, across four samples, from the Ways of Coping Questionnaire. Planning, Positive Reappraisal, and Distancing factors were congruent for comparisons made between U.S. healthcare workers, Chinese healthcare workers, Chinese teachers, and Taiwanese teachers. Additional evidence of congruency was provided on specific factors between specific pairs of groups. The results support the usage of common factors across languages, cultures, and occupational groups but also highlight the importance of not administering a test in a different cultural setting without assessing its dimensionality.     

Socialized reflexivity and self‐exertion: Mandala Model of Self and its role in mental health

The Mandala Model of Self (MMS) refers to the well‐functioning self leading to ultimate happiness in various cultures. This research provides the first empirical examination of the role of MMS in mental health in Confucian societies. The MMS Scale (MMSS) was developed, and its psychometric properties are described. A correlational study demonstrated that the MMSS, along with its two factors—socialized reflexivity and self‐exertion—validly measures certain mental health constructs. A quasi‐experimental study reliably distinguished persons engaged in the cultivation of the Mandala self from those who had not. Finally, a study with adolescents demonstrated that the scores of the MMSS are a better predictor of resilience than is extroversion or neuroticism. The present research provides empirical support for the theory underlying the MMS and its key contribution to mental health.
