Looking After Number One: Associations Between Psychopathic Traits and Measures of Social Motivation and Functioning in a Community Sample of Males

Individuals with high levels of psychopathic traits do not typically form enduring bonds with others. However, few studies have documented the associations between psychopathic traits and social functioning. This study systematically explored associations between psychopathic traits and a number of measures characterising social/material goals, social beliefs and the need for belonging, providing a comprehensive assessment of aspects of social functioning associated with psychopathic personality traits. Additionally, a novel experimental vignettes task assessed the extent to which participants identified dominance in themselves and admired this trait in others. Community males with high levels of psychopathic traits appeared not to be motivated by meaningful, long-term relationships. Instead, they seemed to be motivated by goals relating to their own image and financial success. Additionally, these individuals admired dominance in others, but did not clearly identify this trait in themselves. Thus, this study is one of the first to empirically explore multiple areas of social functioning in relation to psychopathic traits, with a view to understanding the social motivations of individuals with high levels of these traits. The findings provide empirical evidence that individuals with high levels of psychopathic traits seem motivated to look after themselves, but not others.     

Stereotype threat,test anxiety,and mathematics performance

We investigated the combined effects of stereotype threat and trait test anxiety on mathematics test performance. Stereotype threat and test anxiety interacted with each other in affecting performance. Trait test anxiety predicted performance only in a diagnostic condition that prevented stereotype threat by stereotype denial. A state measure of fear of the test mediated this influence. However, stereotype threat reduced the performance of low test-anxious participants to the level of high test-anxious participants. Thus, stereotype threat affected persons low in test anxiety but not persons high in test anxiety. Both phenomena apparently share common mechanisms through which they impair performance.     

Training‐induced recovery of low‐level vision followed by mid‐level perceptual improvements in developmental object and face agnosia

Long‐term deprivation of normal visual inputs can cause perceptual impairments at various levels of visual function, from basic visual acuity deficits, through mid‐level deficits such as contour integration and motion coherence, to high‐level face and object agnosia. Yet it is unclear whether training during adulthood, at a post‐developmental stage of the adult visual system, can overcome such developmental impairments. Here, we visually trained LG, a developmental object and face agnosic individual. Prior to training, at the age of 20, LG's basic and mid‐level visual functions such as visual acuity, crowding effects, and contour integration were underdeveloped relative to normal adult vision, corresponding to or poorer than those of 5–6 year olds (Gilaie‐Dotan, Perry, Bonneh, Malach & Bentin, 2009). Intensive visual training, based on lateral interactions, was applied for a period of 9 months. LG's directly trained but also untrained visual functions such as visual acuity, crowding, binocular stereopsis and also mid‐level contour integration improved significantly and reached near‐age‐level performance, with long‐term (over 4 years) persistence. Moreover, mid‐level functions that were tested post‐training were found to be normal in LG. Some possible subtle improvement was observed in LG's higher‐order visual functions such as object recognition and part integration, while LG's face perception skills have not improved thus far. These results suggest that corrective training at a post‐developmental stage, even in the adult visual system, can prove effective, and its enduring effects are the basis for a revival of a developmental cascade that can lead to reduced perceptual impairments.     

Verbal learning and memory as measured by the Rey-Auditory Verbal Learning Test: ADHD with and without learning disabilities

The primary purpose of the present study is to examine the effects of attention deficits, learning disability, and the combined effects of both on the learning and memory processes, as measured by the Rey Auditory Verbal Learning Test (AVLT). Thirty children (age range 12-17) diagnosed with attention deficit/hyperactivity disorder (ADHD), 18 children (age range 11-17) diagnosed with learning disabilities (LD), and 64 children (age range 12-17) diagnosed with ADHD as well as with LD, and 28, 18, and 62 matched controls, respectively, participated in this study. It was found that the children diagnosed with ADHD did not differ in any of the verbal learning and memory measures derived from the Rey AVLT. The group with LD was impaired in the overall number of words recalled across the learning phase. Performance of the children diagnosed with ADHD +LD showed a similar impairment as the group with LD (i.e., overall amount of words learned) and, in addition, their retrieval efficiency was also impaired. In conclusion, this study indicates that verbal memory is preserved in children with ADHD if they have no LD and their intelligence is in the normal range or above. LD by itself leads to difficulties in acquisition, but the combination of ADHD+LD leads to additional impairment in retrieval processes.     

Phonon densities of states of gamma-cerium and delta-cerium measured by time-of-flight inelastic neutron scattering

Time-of-flight inelastic neutron scattering spectra were measured on cerium metal at temperatures near the fcc (gamma)-to-bcc (delta) transition temperature. Phonon density-of-states (DOS) curves were extracted from data acquired over a wide range of momentum transfers. A large softening of the phonon DOS was found in going from gamma-cerium to delta-cerium, and this accounts for an increase in vibrational entropy of (0.71 +/- 0.05)k _B/atom. To be consistent with the latent heat of the gamma-delta transition, this increase in vibrational entropy must be accompanied by a large decrease in electronic entropy. The results not only confirm the recent discovery of a significant electronic contribution to the gamma-delta transition but also suggest that it may be twice that previously reported.     

The kinetics of anodic oxide growth

Abstract

The process of anodic oxide growth has been investigated. It is shown that the obtained experimental results confirm the Fehlner-Mott oxidation model in the case of InSb, a typical compound of the 111-V group. We also present a kinetic theory of the anion migration in the formed oxide. The theory is based on the following assumptions. (a) The only species which moves through the formed oxide is the OH^? anion. (b) The chemical reactions of OH^? with In³⁺ and Sb³⁺ cations take place simultaneously and independently, in a thin layer of the oxide/InSb interface. The resulting solution of the kinetic equations describes the anion distribution in the formed oxide. A simple expression for the rate of oxidation is obtained. Another possible application of the presented theory is suggested.     

Placebo: Análisis conceptual de un constructo en transición

RESUMEN

Los autores comienzan planteando que las opiniones vertidas en algunas revisiones acerca del constructo placebo son respuestas a la evolución actual hacia el empleo de conceptualizaciones más cognitivas en la psicoterapia. Seguidamente ofrecen un breve repaso histórico de esta noción, para centrarse en sus aspectos denotativos y connotativos. Respecto a los primeros, revisan las dos metáforas dominantes que pueden encontrarse en la literatura: (a) los placebos como ingredientes inertes en vez de activos y (b) como agentes no específicos en vez de específicos. En relación con los aspectos connotativos, examinan las cuatro fuentes de donde proceden y afirman que distinguiendo entre los verdaderos efectos placebo y los artefactos de medida las connotaciones negativas de este constructo son inmerecidas. Seguidamente abordan su utilidad en la evaluación de la eficacia de la psicoterapia y responden a la cuestión de si las terapias actuales son más eficaces que el tratamiento inespecífico. Este trabajo concluye que como el placebo ha de jugar un papel crucial en la evaluación científica de la psicoterapia, rechazarlo prematuramente constituiría una regresión conceptual y metodológica.     

Recovery opportunities,work–home conflict,and emotional exhaustion among hematologists and oncologists in private practice

Hematologists and oncologists in private practice play a central role in the care provided for cancer patients. The present study analyzes stress and relaxation aspects in the work of hematologists and oncologists in private practice in Germany in relation to emotional exhaustion, as a core dimension of burnout syndrome. The study focuses on the opportunities for internal recovery using breaks and time out during the working day, the frequency of working on weekends and on vacation, and the physician’s work–home and home–work conflict. Postulated associations between the constructs were analyzed using a structural equation model. If work leads to conflicts in private life (work–home conflict), it is associated with greater emotional exhaustion. Working frequently at the weekend is associated with greater work–home conflict and indirectly with greater emotional exhaustion. By contrast, the availability of opportunities to relax and recover during the working day is associated with less work–home conflict and indirectly with less emotional exhaustion. These results underline the importance of internal recovery opportunities during the working day and a successful interplay between working and private life for the health of outpatient hematologists and oncologists.
