Dissociative effects of viewpoint and semantic priming on action and semantic decisions: evidence for dual routes to action from vision

This article reports evidence that two variables—object viewpoint and semantic priming—differentially affect action and semantic decisions to objects. Changing the viewing angle of an object, so that its graspable parts are oriented away from observers, disrupted action decisions but had little effect on semantic categorization. In contrast, semantic priming influenced semantic categorization and object naming, but not action decisions. Action priming, however, did not affect performance. These selective effects are consistent with the existence of separate semantic and direct (nonsemantic) routes to action from vision.     

A meta-analysis of support variables and well-being in ethnic minority populations

Aims: The importance of social support as a predictor of well-being has been documented in the literature for decades. The extent to which social support may be uniquely relevant to the well-being of ethnic minority populations has not yet been empirically supported with meta-analytic techniques. The current meta-analytic study attempted to clarify the nuances of the relationship between support and well-being in ethnic minority populations and to identify what moderators may be relevant to understanding such relationships. Method: Data from 111 articles were included in the analyses that examined both the main effects and moderators of the relationship between social support and well-being. Results: Overall findings revealed a greater effect size (ES) between support and positive well-being (r = .38) than between support and negative well-being (r = −.27). Significant moderators included the proportion of females in the sample, age of the participants, and nature of support. Several ES differences were found in support type and ethnic group interactions as well. Conclusions: Implications of these data include the importance of social support enhancement in efforts to increase the positive well-being and attending to gender and other cultural modifiers in future studies of social support with racial and ethnic minorities.     

Imago Dei and human rights protections of forced migrants: A North Korean case study

In this article, I examine the significance of the theological concept of Imago Dei in recognizing the dignity of North Koreans and in necessitating socio-structural transformation for their human rights protections in South Korean society. North Koreans residing in South Korea are an example case of forced migrants who experience mistreatment and discrimination in their destination country. In this reality, the concept of Imago Dei can call South Koreans to recognize North Koreans’ dignity. It can further criticize South Korea's social structure that intensifies North Koreas’ maladjustment in South Korean society, and necessitate institutional levels of transformation.     

Punishment sensitivity and risk taking in depressed mood

Motivation and Emotion - Individuals with high levels of depressive symptoms find rewards to be less reinforcing and punishment more aversive, which may lead them to avoid risk taking. To examine...     

Effortful Control in “Hot” and “Cool” Tasks Differentially Predicts Children’s Behavior Problems and Academic Performance

Effortful control (EC), the capacity to deliberately suppress a dominant response and perform a subdominant response, rapidly developing in toddler and preschool age, has been shown to be a robust predictor of children’s adjustment. Not settled, however, is whether a view of EC as a heterogeneous rather than unidimensional construct may offer advantages in the context of predicting diverse developmental outcomes. This study focused on the potential distinction between “hot” EC function (delay-of-gratification tasks that called for suppressing an emotionally charged response) and more abstract “cool” EC functions (motor inhibition tasks, suppressing-initiating response or Go-No Go tasks, and effortful attention or Stroop-like tasks). Children (N?=?100) were observed performing EC tasks at 38 and 52 months. Mothers, fathers, and teachers rated children’s behavior problems and academic performance at 67, 80, and 100 months, and children participated in a clinical interview at 100 months. Structural Equation Modeling (SEM) analyses with latent variables produced consistent findings across all informants: Children’s scores in “hot” EC tasks, presumably engaging emotion regulation skills, predicted behavior problems but not academic performance, whereas their scores in “cool” EC tasks, specifically those engaging effortful attention, predicted academic performance but not behavior problems. The models of EC as a heterogeneous construct offered some advantages over the unidimensional models. Methodological and clinical implications of the findings are discussed.     

Mindfulness and negative affectivity in real time: a within-person process model

ABSTRACT

To extend our understanding of the proximal etiology of personality pathology, this study examined the dynamic, in-the-moment relations between mindfulness and negative affectivity (NA; emotional lability, anxiousness, separation insecurity) as defined by the alternative model for personality disorders. We tested predictions based upon the Monitor and Acceptance Theory that when people monitored their attention judgmentally, their state NA would be higher than usual; by contrast, when they monitored their attention nonjudgmentally, their state NA would be lower than usual. Sixty-five undergraduates participated in an experience sampling study wherein they completed five reports per day for eight days about their states of mindfulness and NA. Multi-level models revealed an interaction wherein participants exhibited more state NA when they monitored their attention judgmentally than when they monitored their attention nonjudgmentally. Analyses of simple slopes revealed that participants exhibited more state NA than usual when they monitored their attention judgmentally. These findings emerged for only one of two attention monitoring processes, however: monitoring relations between thoughts, emotions, and behaviours, but not monitoring sensory stimuli. Analyses including non-reactivity instead of nonjudgment replicated these findings. Implications for theory, research, and treatment are discussed.     

Dielectric behavior of aerosol-deposited Mn-modified PZT–PZN thick films

We report the dielectric and ferroelectric behavior of thick films, ～10 µm, synthesized by aerosol deposition. The base composition of the films was selected to be 0.9Pb(Zr_0.52Ti_0.48)O₃–0.1Pb(Zn_1/3Nb_2/3)O₃ (PZT–PZN), which was modified with Mn to 0.9Pb(Zr_0.52Ti_0.48)O₃–0.1Pb(Zn_1/3Nb_2/3) O₃–0.52 wt% MnO₂ (PZT–PZN–Mn) in order to induce hardening. The polarization dynamics of the synthesized films was modeled using the theory developed for magnetic glassy systems. It was found that the substitution of Mn significantly (1) enhances the relaxation time, (2) reduces the magnitude of dielectric constant and dielectric loss, and (3) enhances the internal bias field. The results indicate the presence of domain wall pinning by the formation of defect dipoles.
