Can Constructive Thinking Predict Decision Making?

We assume that executive function constitutes an integrated set of cognitive processes that mediate working memory, planning, inhibition, flexibility, and decision making. Despite the acknowledged theoretical connection between executive function processes and emotional intelligence, such relationships have rarely been investigated. The purpose of this study was to examine the potential relationship between constructive thinking, conceived as a component of emotional intelligence, and executive function, as indexed by various existing neuropsychological and experimental instruments. We used the Constructive Thinking Inventory as a measure of emotional intelligence. We found that some constructive thinking subscales were able to predict distinct executive function variables. Emotional Coping, Categorical Thinking, and Esoteric Thinking subscales explained performance on various measures of executive function. Thus, we conclude that intervention programs designed to train a specific component of emotional intelligence, namely constructive thinking, could also facilitate performance in executive function processes, and vice versa.

Free viewing perceptual asymmetries for judgment of brightness and quantity: dependence on stimulus orientation

Previous research has indicated that normals exhibit strong leftward biases during free-viewing perceptual judgments of brightness and quantity. When participants view two symmetrical objects and they are forced to choose which object appears darker or more numerous, participants usually select the stimulus with the relevant feature on the left side. The present study investigated the possibility that these perceptual asymmetries are dependent on scanning a stimulus horizontally across the midline by administering a task with two rectangular reversed stimuli presented either horizontally or vertically. When the stimuli were presented horizontally (crossing the midline), participants exhibited leftward biases, but these biases disappeared when the stimuli were presented vertically. This result supports the position that free-viewing perceptual asymmetries are dependent on scanning the stimuli across the midline.     

Juggling with bubbles in cylindrical ferrofluid foams

Monodisperse foams in long cylinders exhibit ordered spiral structures. We have made ferrofluid foams of this kind and find that they can be manipulated in a variety of ways by an external magnetic field. Effects include morphological changes, twisting of structures and size control in the bubble formation process. This offers a promising technique for the efficient transport, switching and combining of samples in fluidic networks, possibly on the microfluidic scale.     

How forgiveness,purpose, and religiosity are related to the mental health and well-being of youth: A review of the literature

Youth today often face challenges that can undermine important opportunities to achieve their full potential in school, in the workplace, in relationships, and within themselves. This article reviews the literature addressing certain personal qualities that have shown promise in the promotion of youth resilience against such threats. More specifically, the values of forgiveness, purpose, and religiosity are considered. The purpose of this literature review is to bring attention to the promise that this body of research has shown and to encourage the continued empirical study of forgiveness, purpose, and religiosity, particularly within the realm of youth mental health and well-being. First, operational definitions of these constructs are discussed. This is followed by discussion of theoretical, clinical, and empirical support for the benefits of strongly upholding values related to forgiveness, purpose, and religiosity during youth. Finally, practical implications and directions for future research are offered.     

Handedness and depression in university students: a sex by handedness interaction

Previous research has indicated that there is an increased incidence of left-handedness in samples of depressed individuals. We administered the Beck Depression Inventory (BDI) to a sample of 541 undergraduate students. Left-handed males showed significant elevation of BDI scores. It is unlikely that this result is due to decreased right hemisphere activity or sex-role conflicts. However, one possibility is that known differences in male steroid hormones levels between right- and left-handers contributed to this effect. Press     

Hippocampal gene expression profiling in spatial discrimination learning

Learning and long-term memory are thought to involve temporally defined changes in gene expression that lead to the strengthening of synaptic connections in selected brain regions. We used cDNA microarrays to study hippocampal gene expression in animals trained in a spatial discrimination-learning paradigm. Our analysis identified 19 genes that showed statistically significant changes in expression when comparing Nai;ve versus Trained animals. We confirmed the changes in expression for the genes encoding the nuclear protein prothymosin(alpha) and the delta-1 opioid receptor (DOR1) by Northern blotting or in situ hybridization. In additional studies, laser-capture microdissection (LCM) allowed us to obtain enriched neuronal populations from the dentate gyrus, CA1, and CA3 subregions of the hippocampus from Nai;ve, Pseudotrained, and spatially Trained animals. Real-time PCR examined the spatial learning specificity of hippocampal modulation of the genes encoding protein kinase B (PKB, also known as Akt), protein kinase C(delta) (PKC(delta)), cell adhesion kinase(beta) (CAK(beta), also known as Pyk2), and receptor protein tyrosine phosphatase(zeta/beta) (RPTP(zeta/beta)). These studies showed subregion specificity of spatial learning-induced changes in gene expression within the hippocampus, a feature that was particular to each gene studied. We suggest that statistically valid gene expression profiles generated with cDNA microarrays may provide important insights as to the cellular and molecular events subserving learning and memory processes in the brain.     

Enhancing school-based prevention and youth development through coordinated social,emotional, and academic learning

A comprehensive mission for schools is to educate students to be knowledgeable, responsible, socially skilled, healthy, caring, and contributing citizens. This mission is supported by the growing number of school-based prevention and youth development programs. Yet, the current impact of these programs is limited because of insufficient coordination with other components of school operations and inattention to implementation and evaluation factors necessary for strong program impact and sustainability. Widespread implementation of beneficial prevention programming requires further development of research-based, comprehensive school reform models that improve social, health, and academic outcomes; educational policies that demand accountability for fostering children's full development; professional development that prepares and supports educators to implement programs effectively; and systematic monitoring and evaluation to guide school improvement.     

The moderating role of early traumatic experiences on the association of schizotypal traits with visual perception

The findings on the association of schizotypal traits with the perception of visual illusions are scarce and inconsistent and have not taken into consideration potential effects of childhood traumatic experiences, a risk factor for schizophrenia-spectrum conditions. Thus, the present study addressed the question of potential moderating effects of early traumatic experiences on the association between different aspects of schizotypal traits with the perception of the Müller-Lyer and Navon's Hierarchical Letters (NHL) illusions. The study revealed that (a) increased suspiciousness was associated with increased liability to the Müller-Lyer illusion, when the exposure to traumatic events was high, whereas the opposite pattern was true when the exposure to traumatic events was low; (b) negative schizotypy was associated with more accurate global perception, and high disorganized schizotypy was associated with superior accuracy when target letters were present during the NHL illusion, when early traumatic experiences were at lower levels; and (c) high negative, disorganized, and total schizotypy were associated with lower accuracy when target letters were present in the NHL paradigm, when early traumatic experiences were at higher levels. The findings of the study suggest that early traumatic events differentially moderate the relationship between various aspects of schizotypal traits and visual perceptual processing.     

Schools as a source of stress to children: An analysis of causal and ameliorative influences

An analysis of factors leading schools to be a significant source of stress to children is presented. Debilitating school stress is seen as linked to forces, including some in prominent movements for school “reform,” that push schools to overemphasize academic acceleration, competition, evaluation, and test-based accountability. The paradoxical effects of these forces are to impede acquisition of academic skills and minimize opportunities for children to develop crucial competencies needed for citizenship, responsible adulthood, parenthood, and management of the complex world of work. Recommendations based on developmental and empirical considerations are presented to reduce the debilitating stress in our schools. The tenacious leadership and coordinated, sustained planning required to enact some of these recommendations is noted and encouraged.
