First-trial adaptation to prism exposure: artifact of visual capture

Terminal target-pointing error on the 1st trial of exposure to optical displacement is usually less than is expected from the optical displacement magnitude. The authors confirmed 1st-trial adaptation in the task of pointing toward optically displaced targets while visual feedback was delayed until movement completion. Measurement of head-shoulder posture while participants (N = 24) viewed the optically displaced field revealed that their shoulders felt turned in the direction opposite to the displacement (visual capture), accounting for all but about 4% to 10% of 1st-trial adaptation. First-trial adaptation was unrelated to realignment aftereffects. First-trial adaptation is largely an artifact of the asymmetry of the structured visual field produced by optical displacement, which induces a felt body rotation, thereby reducing the effective optical displacement.     

What plausibly affects plausibility? Concept coherence and distributional word coherence as factors influencing plausibility judgments

Our goal was to investigate the basis of human plausibility judgements. Previous research had suggested that plausibility is affected by two factors: concept coherence (the inferences made between parts of a discourse) and word coherence (the distributional properties of the words used). In two experiments, participants were asked to rate the plausibility of sentence pairs describing events. In the first, we manipulated concept coherence by using different inference types to link the sentences in a pair (e.g., causal or temporal). In the second, we manipulated word coherence by using latent semantic analysis, so two sentence pairs describing the same event had different distributional properties. The results showed that inference type affects plausibility; sentence pairs linked by causal inferences were rated highest, followed by attributal, temporal, and unrelated inferences. The distributional manipulations had no reliable effect on plausibility ratings. We conclude that the processes involved in rating plausibility are based on evaluating concept coherence, not word coherence.     

Mental balance and well-being: building bridges between Buddhism and Western psychology

Clinical psychology has focused primarily on the diagnosis and treatment of mental disease, and only recently has scientific attention turned to understanding and cultivating positive mental health. The Buddhist tradition, on the other hand, has focused for over 2,500 years on cultivating exceptional states of mental well-being as well as identifying and treating psychological problems. This article attempts to draw on centuries of Buddhist experiential and theoretical inquiry as well as current Western experimental research to highlight specific themes that are particularly relevant to exploring the nature of mental health. Specifically, the authors discuss the nature of mental well-being and then present an innovative model of how to attain such well-being through the cultivation of four types of mental balance: conative, attentional, cognitive, and affective.     

Sexual harassment and social justice: reflections on the distance yet to go

Despite progress, protections remain inadequate for victims who bring legal claims of sexual harassment. The process for damages determination frequently increases harm and undercuts the policy initiatives enshrined in Title VII. The author critiques this process, focusing on misuse of psychological examinations and failure of the federal "rape shield" law to adequately protect plaintiffs. The author suggests possible reforms, including removing caps on Title VII damages, minimum awards (i.e., liquidated damages) upon proof of liability, and strategies for educating juries on the harms of harassment that do not exacerbate them, and concludes with a call for professional guidelines for conducting forensic evaluations in sexual harassment cases, thus advancing the policy goal of combating discrimination by encouraging victims to come forward.     

An evaluation of a brief functional analysis format within a vocational setting

We conducted and compared both brief and extended functional analyses of disruptive behaviors for 3 individuals with developmental disabilities who attended a vocational training program. Results demonstrated that the brief assessment identified the function of 2 of the 3 participants' disruptive behavior compared to the extended assessment.     

Learning- and grade-orientation,sex, and prediction of self-reported academic performance

148 undergraduate students completed the LOGO-II scale, a measure of educational orientation, i.e., learning-oriented and grade-oriented attitudes and behaviors, and were asked to report their current and expected grades, as well as their self-assessed academic skill. Generally, learning orientation was positively correlated with academic performance, but grade orientation was negatively correlated with performance. Learning orientation and grade orientation predicted academic performance for men but not women. Implications of these findings, including the possibility of encouraging students to assume a more learning-oriented approach to their education, are discussed.     

LY354740, an mGlu2/3 receptor agonist as a novel approach to treat anxiety/stress

Metabotropic glutamate (mGlu) receptors, which include mGlu1-8 receptors, are a heterogeneous family of G-protein coupled receptors (GPCRs) that function to modulate neuronal excitation and plasticity via pre-synaptic, post-synaptic and glial mechanisms. Agonists for group II mGlu receptors (mGlu2 and mGlu3), such as LY354740, have been shown to suppress enhanced glutamatergic excitations in brain synapses known to be involved in the expression of fear/anxiety in animals and humans. Systemic administration of LY354740 increases open-arm time in the elevated plus maze in mice under conditions of moderate to severe stress, blocks the expression but not development of fear-potentiated startle in rats, prevents lactate-induced panic-like responses in panic-prone rats, and attenuates certain physiological, behavioral, and neurochemical consequences of acute stress in rodents. In these preclinical models, LY354740 does not produce the side-effects (e.g. sedation) that are associated with other anxiolytic agents such as benzodiazepines. Early clinical results with LY354740 have demonstrated safety and efficacy in a human anxiety model (panic provocation induced by CO2 challenge). Collectively, these data indicate mGlu2/3 receptor agonists such as LY354740 represent a promising new approach for treatment of anxiety and stress-related disorders in humans.     

Psychometric properties of the eating disorders inventory-2 among women seeking treatment for binge eating disorder

Psychometric properties of the Eating Disorders Inventory-2 (EDI-2) when used for women with Binge Eating Disorder (BED) are assessed. The EDI-2 was administered to 144 outpatients seeking treatment for BED and 152 outpatients seeking treatment for Bulimia Nervosa (BN). Most EDI-2 scales had acceptable internal consistence for both the BED and BN samples. EDI-2 scales demonstrated adequate stability within a subsample of those with BED who were retested. Confirmatory factor analyses revealed a hypothesized second-order two-factor structure for the original EDI scales for the BED group but not for those with BN. When the provisional EDI-2 scales were included, a two-factor structure was not supported for any group. Some scales differentiated the BED from the BN sample, and the second-order factors correlated with measures of similar constructs. The original EDI scales can be used reliably for those with BED.     

Loneliness as a specific risk factor for depressive symptoms: cross-sectional and longitudinal analyses

The extent to which loneliness is a unique risk factor for depressive symptoms was determined in 2 population-based studies of middle-aged to older adults, and the possible causal influences between loneliness and depressive symptoms were examined longitudinally in the 2nd study. In Study 1, a nationally representative sample of persons aged 54 and older completed a telephone interview as part of a study of health and aging. Higher levels of loneliness were associated with more depressive symptoms, net of the effects of age, gender, ethnicity, education, income, marital status, social support, and perceived stress. In Study 2, detailed measures of loneliness, social support, perceived stress, hostility, and demographic characteristics were collected over a 3-year period from a population-based sample of adults ages 50-67 years from Cook County, Illinois. Loneliness was again associated with more depressive symptoms, net of demographic covariates, marital status, social support, hostility, and perceived stress. Latent variable growth models revealed reciprocal influences over time between loneliness and depressive symptomatology. These data suggest that loneliness and depressive symptomatology can act in a synergistic effect to diminish well-being in middle-aged and older adults.
