Testing the Bivalent Fear of Evaluation Model of Social Anxiety: The Relationship between Fear of Positive Evaluation,Social Anxiety,and Perfectionism

The Bivalent Fear of Evaluation (BFOE) model of social anxiety proposes that fear of negative evaluation (FNE) and fear of positive evaluation (FPE) play distinct roles in social anxiety. Research is however lacking in terms of how FPE is related to perfectionism and how these constructs interact to predict social anxiety. Participants were 382 individuals from the general community and included an oversampling of individuals with social anxiety. Measures of FPE, FNE, perfectionism, and social anxiety were administered. Results were mostly consistent with the predictions made by the BFOE model and showed that accounting for confounding variables, FPE correlated negatively with high standards but positively with maladaptive perfectionism. FNE was also positively correlated with maladaptive perfectionism, but there was no significant relationship between FNE and high standards. Also consistent with BFOE model, both FNE and FPE significantly moderated the relationship between maladaptive perfectionism and social anxiety with the relationship strengthened at high levels of FPE and FNE. These findings provide additional support for the BFOE model and implications are discussed.

听障大学生汉语阅读中的绕口令效应：口语经验和阅读能力的影响

听障者阅读时是否激活语音信息是听障者阅读研究领域的热点问题之一。本研究使用眼动技术,采用绕口令材料,考察口语经验和阅读能力对听障大学生汉语阅读中语音激活的影响。结果发现,口语经验较多且阅读能力较高(OHRH)的听障大学生的绕口令效应大于口语经验较少但阅读能力较高(OLRH)的听障大学生,OLRH组的绕口令效应大于口语经验较少且阅读能力较低(OLRL)的听障大学生。局部指标分析发现OHRH和OLRH组在早期和晚期指标上均存在绕口令效应,OLRL组只在晚期指标上才出现绕口令效应。结果表明,口语经验和阅读能力影响听障大学生汉语阅读中的语音激活。     

Self-Doubt Effects Depend on Beliefs about Ability: Experimental Evidence

Past research has shown negative effects of chronic self-doubt on psychological and performance outcomes. Recent correlational evidence suggests that incremental beliefs about ability ameliorate certain self-doubt effects. The current research examines whether these correlational findings are robust when subjected to experimental testing. In Experiment 1, we manipulated beliefs about ability (incremental vs. entity) and demonstrated that changing beliefs about ability altered responses to self-doubt. For individuals primed with entity beliefs, higher self-doubt was associated with greater nervousness and poorer anagram performance; for individuals primed with incremental beliefs, self-doubt had no significant effects. Experiment 2 was a 2 (manipulated belief: incremental vs. entity) × 2 (self-doubt: doubt induction vs. control) factorial design. The result showed that self-doubt induction lowered self-esteem relative to control when people were primed with entity beliefs but did not affect self-esteem when incremental beliefs were primed. However, Experiment 1 results on affect and performance were not replicated in Experiment 2. Thus, although we provide some causal evidence that inducing individuals to adopt an ability-is-malleable mindset reduces the negative effects of self-doubt, further experimental work is required to study the moderating role of mindsets for self-doubt effects.     

Effect of pressure on the mechanical and dynamical stability of NaAlSi

The effects of pressure on the mechanical and dynamical stability of NaAlSi have been fully investigated by first-principles calculations within the generalised gradient approximation (GGA). The obtained results show that the optimised lattice constants, atomic positions and elastic constants at ambient pressure are in good agreement with the available experimental and theoretical data. The lattice constants decrease monotonically with increasing pressure. The elastic constant C₁₁, C₁₂, C₁₃, C₃₃ and C₆₆ increase while C₄₄ decreases with increasing pressure. It is found that NaAlSi is mechanically unstable when the pressure is above 25.97?GPa. The phonon-dispersion curves along several high symmetry lines are obtained. The phonon frequencies at the Z point decrease with increasing pressure and completely soften to zero at 27.52?GPa, further confirming the structural instability of NaAlSi.     

Mathematics ability and related skills in preschoolers born very preterm

Children born very preterm (VPT) are at risk for academic, behavioral, and/or emotional problems. Mathematics is a particular weakness and better understanding of the relationship between preterm birth and early mathematics ability is needed, particularly as early as possible to aid in early intervention. Preschoolers born VPT (n = 58) and those born full term (FT; n = 29) were administered a large battery of measures within 6 months of beginning kindergarten. A multiple-mediation model was utilized to characterize the difference in skills underlying mathematics ability between groups. Children born VPT performed significantly worse than FT-born children on a measure of mathematics ability as well as full-scale IQ, verbal skills, visual–motor integration, phonological awareness, phonological working memory, motor skills, and executive functioning. Mathematics was significantly correlated with verbal skills, visual–motor integration, phonological processing, and motor skills across both groups. When entered into the mediation model, verbal skills, visual–motor integration, and phonological awareness were significant mediators of the group differences. This analysis provides insights into the pre-academic skills that are weak in preschoolers born VPT and their relationship to mathematics. It is important to identify children who will have difficulties as early as possible, particularly for VPT children who are at higher risk for academic difficulties. Therefore, this model may be used in evaluating VPT children for emerging difficulties as well as an indicator that if other weaknesses are found, an assessment of mathematics should be conducted.     

Unfounded beliefs among teachers: The interactive role of rationality priming and cognitive ability

Previous research suggests that unfounded beliefs (UB)—such as conspiracist beliefs and beliefs in the supernatural—stem from similar cognitive and motivational mechanisms. More specifically, it has been demonstrated that cognitive ability is negatively associated with UB but only among individuals who value epistemic rationality. The present study goes beyond previous correlational studies by examining whether the negative association between cognitive ability and UB can be strengthened through a subtle rationality prime. In a large scale online experiment (N = 762 French teachers), we demonstrate that priming rationality (vs. control) does enhance the negative relationship between cognitive ability and adherence to supernatural beliefs, as well as conspiracy mentality (d = 0.2). This effect was not obtained for illusory pattern perception. This study's usefulness as a “proof of concept” for future interventions aimed at reducing UB prevalence among the general public is discussed.     

Efficacy of a Brief,School‐Based Bystander Bullying Intervention on High School Students' Alcohol Use

The authors examined the efficacy of a brief bystander bullying intervention on reducing alcohol use among high school students (N = 61). As hypothesized, high‐risk drinkers in the intervention group reported reduced drinking compared with control students at a 30‐day follow‐up.     

攻击性信息对脆弱型高自尊大学生返回抑制的影响机制

为考察攻击性信息对脆弱型高自尊大学生返回抑制的影响机制,本研究采用线索靶子范式,分别将攻击性及中性词汇作为靶子（实验1）和线索（实验2）呈现。实验1发现,脆弱型和安全型高自尊组对攻击性信息均存在注意捕获,从而使攻击性信息的返回抑制量降低。实验2发现,脆弱型高自尊组对攻击性信息存在注意解除困难,从而使攻击性信息的返回抑制量降低。脆弱型高自尊大学生对攻击性信息存在过多的注意维持,降低了视觉搜索效率,这可是其好发攻击性行为的潜在认知加工机制。
