Early childhood trichotillomania: Initial considerations on phenomenology,treatment, and future directions

Historically, trichotillomania (TTM) in young children (0–3 years old) generally has been considered to be a benign habit that is clinically distinct from the TTM seen in older children and adults. However, early childhood TTM can be an impairing pathological disorder that merits formal intervention. The present article reviews the extant literature on TTM in young children, highlighting the limited available phenomenological data. We discuss a behavioral approach to conceptualization and treatment, highlighting core intervention strategies in three early childhood TTM cases seen in our clinic. We conclude by discussing areas in need of further empirical attention.     

Finger coordination under artificial changes in finger strength feedback: a study using analytical inverse optimization

A recently developed method of analytical inverse optimization (ANIO) was used to compute cost functions based on sets of experimental observations in 4-finger pressing tasks with accurate total force and moment production. In different series, feedback on total force and moment was provided using the index finger force at its value, doubled, or halved. Finger force data across different force-moment combinations formed a plane. This allowed reconstructing cost functions as 2nd-order polynomials with linear terms. Changes in the coefficients of the cost function across the 3 series allowed the authors to offer a biomechanical interpretation related to constraints on finger forces with different lever arms. ANIO allows the authors to describe preferred regions within the space of solutions for redundant tasks in terms of cost functions.     

Suicide among foreign residents of Japan

The suicide rate of Koreans living in Japan is twice as high as that of Koreans in South Korea. Reasons for this high suicide rate are discussed, including effects of economic crises and discrimination.     

Does d-Cycloserine Augmentation of CBT Improve Therapeutic Homework Compliance for Pediatric Obsessive–Compulsive Disorder?

Clinical studies in adults and children with obsessive–compulsive disorder (OCD) have shown that d-cycloserine (DCS) can improve treatment response by enhancing fear extinction learning during exposure-based psychotherapy. Some have hypothesized that improved treatment response is a function of increased compliance and engagement in therapeutic homework tasks, a core component of behavioral treatment. The present study examined the relationship between DCS augmented cognitive-behavioral therapy (CBT) and homework compliance in a double-blind, placebo controlled trial with 30 youth with OCD. All children received 10 CBT sessions, the last seven of which included exposure and response prevention paired with DCS or placebo dosed 1 h before the session started. Results suggested that DCS augmented CBT did not predict improved homework compliance over the course of treatment, relative to the placebo augmented CBT group. However, when groups were collapsed, homework compliance was directly associated with treatment outcome. These findings suggest that while DCS may not increase homework compliance over time, more generally, homework compliance is an integral part of pediatric OCD treatment outcome.     

Examining Trajectories of Early Adolescents’ Life Satisfaction in South Korea Using a Growth Mixture Model

Various aspects of early adolescence can have a key impact on adult life satisfaction. This study applied a growth mixture model to examine the trajectories of early adolescents’ life satisfaction and test the effects of individual (sex, subjective achievement, and self-esteem) and social factors (school adjustment and peer attachment) thereon. For this purpose, a growth mixture model was used on the fifth- (grade five), sixth- (grade six), and seventh- (grade seven) year panel data of 1917 grade one students from the Korean Children and Youth Panel Survey (2010–2016, National Youth Policy Institute), excluding missing samples. Participants were 990 boys (51.6%) and 927 girls (48.4%). The results indicated that the trajectories of life satisfaction could be categorized into three groups: “High Level-decreasing” (57.19%), “Moderate Level-stable” (37.62%), and “Low Level-increasing” (5.19%). Predictors for each class exhibited that female students and individuals with higher levels of self-esteem and school adjustment were more likely to be in the “Low Level-increasing” and “Moderate Level-stable” groups compared to male students and those reporting lower levels of self-esteem and school adjustment. Moreover, students with higher peer attachment were more likely to be in the “Low Level-increasing” group compared to the “High Level-decreasing” group. Educational implications to achieve positive life satisfaction by determining the influence of the predictors for each trajectory are outlined.

     

Dimensions of Religiousness and Spirituality as Predictors of Well-Being in Advanced Chronic Heart Failure Patients

We examined relationships between seven dimensions of religion/spirituality (RS) (forgiveness, daily spiritual experiences, belief in afterlife, religious identity, religious support, public practices, and positive RS coping) and three dimensions of well-being (physical, mental, and existential) in a sample of 111 patients with advanced chronic heart failure. Participants completed questionnaires at baseline and 3 months later. Results showed that fairly high levels of RS were reported on all seven dimensions. Furthermore, RS dimensions were differentially related to well-being. No aspect of RS was related to physical well-being, and only a few aspects were related to mental well-being. Forgiveness was related to less subsequent depression, while belief in afterlife was related to poorer mental health. All aspects of RS were related to at least one aspect of existential well-being. In particularly, daily spiritual experiences were linked with higher existential well-being and predicted less subsequent spiritual strain. These results are consistent with the view that in advanced disease, RS may not affect physical well-being but may have potent influences on other aspects of well-being, particularly existential aspects.     

Causal explanation in the face of contradiction

Previous work has shown that predictions can be mediated by mechanistic beliefs. The present study shows that such mediation only occurs in the face of contradictory, and not corroborative, evidence. In four experiments, we presented participants with causal statements describing a common-cause structure (E₁←C→E₂). Then we informed them of the states of C and E₁ and asked them to judge the likelihood of E₂. In Experiments 1 and 2, we manipulated whether the mechanisms supporting the two effects were the same or different, and whether the evidence presented confirmed or contradicted the participants’ expectations. The relation between the mechanisms only influenced predictions when evidence contradicted the expectations, but not when it was consistent. In Experiments 3 and 4, we used a common-cause structure with identical mechanisms. We manipulated the order in which predictions were made. When confirmatory predictions were made before contradictory predictions, mechanistic modulation was not observed in the confirmatory case. In contrast, the modulation was found when confirmatory predictions were made after contradictory ones. The results support the contradiction hypothesis that causal structure is revised during prediction, but only in the face of unexpected evidence.     

Discourse on medicine: meditative and calculative approaches to ethics from an international perspective

Heidegger’s two modes of thinking, calculative and meditative, were used as the thematic basis for this qualitative study of physicians from seven countries (Canada, China, India, Ireland, Japan, Korea, & Thailand). Focus groups were conducted in each country with 69 physicians who cared for the elderly. Results suggest that physicians perceived ethical issues primarily through the lens of calculative thinking (76%) with emphasis on economic concerns. Meditative responses represented 24% of the statements and were mostly generated by Canadian physicians whose patients typically were not faced with economic barriers to treatment due to Canada’s universal health care system.     

The ironic impact of intergroup apologies on intergroup attitudes: Understanding the role of perceived power for post‐apology outgroup attitudes

The present research investigates how intergroup apologies, defined as apologies between two groups, affect perceived remorse and outgroup attitudes (e.g., explicit and implicit), in the context of power asymmetries. We recruited participants from two countries that differ in perceived power: South Korea and the United States. Participants read a vignette describing a violent act committed by an outgroup member (Korean or American), with or without an intergroup apology. Participants answered questions assessing perceived remorse and explicit attitudes toward the outgroup, followed by the Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998). Results revealed that Koreans perceived less remorse following an intergroup apology from the United States, compared to when they did not read an intergroup apology. Further, a mediated moderation analysis indicated that perceived remorse mediated the relationship between apology and explicit attitudes towards the United States. However, an analogous effect for implicit attitudes was only marginally significant. In contrast, among American participants, no effect of the apology on perceived remorse, explicit attitudes, or implicit attitudes and no evidence for a mediation was found. We discuss the implications of these effects on understanding the effectiveness of intergroup apologies between countries that differ in perceived power.
