Calculation of alloying effect on formation enthalpy of TiCu intermetallics from first-principles calculations for designing Ti–Cu-system metallic glasses

The effect of alloying on the formation enthalpy of TiCu intermetallics was investigated via first-principles calculations to propose a new design method for Ti–Cu-system metallic glasses. The calculation results showed good agreement with the reported experimental results that Ni, Pd, Sn and Zr improve this system’s glass-forming ability. According to the calculation results, a Ti–Zr–Cu–Ga system was designed as a potential new bulk Ti-based metallic glass, and a bulk sample with a 2-mm diameter was fabricated.     

5～6岁不同数学能力水平儿童的执行功能差异研究

为了考察不同数学能力水平儿童的执行功能差异,根据331名学前儿童的数学能力得分选取了潜在数学学习困难儿童组、低分组、典型发展儿童组和数学优秀组等4个实验组。首先分析了各组儿童的执行功能差异特点,之后使用判别分析进一步探索了各执行功能子结构对儿童早期数学能力差异分组的贡献。结果表明:相对于典型发展儿童组,潜在数学学习困难儿童在执行功能的更新、抑制和转换方面普遍缺损;低分组儿童则仅表现出数字更新能力不足;数学优秀组在数字更新和有时间要求的认知转换方面比典型发展组有明显优势。进一步判别分析表明,对早期数学能力差异分组贡献最大的并非独立执行功能子结构,而是更新和转换的共同因素结构。     

Hearing From Both Sides: Differences Between Liberal and Conservative Attitudes Toward Scientific and Experiential Evidence

Two studies examined how political ideology relates to attitudes towards opposing scientific and nonscientific perspectives on apolitical topics. Participants read an article excerpt containing quotes from a researcher debunking a common misconception, such as the existence of lucky streaks in games of chance. They also read the perspective of someone who rejected the researcher in favor of personal experience, either in the form of a quote in the article from a relevant professional (e.g., a casino manager, Study 1) or a comment from a purported previous respondent with no clear expertise (Study 2). In both studies, conservatives, compared to liberals, evaluated the views of the scientist and the person rejecting the science as closer in legitimacy. Differences in evaluation of the science rejecter were mediated by conservatives' heightened intuitive thinking. By spotlighting how partisans evaluate nonscientific perspectives alongside science and by focusing on apolitical topics, these results bring new clarity to the debate on whether conservatives are more biased than liberals in attitudes towards science.

Linking metaphor comprehension with analogical reasoning: Evidence from typical development and autism spectrum disorder

We examined the relationship between metaphor comprehension and verbal analogical reasoning in young adults who were either typically developing (TD) or diagnosed with Autism Spectrum Disorder (ASD). The ASD sample was highly educated and high in verbal ability, and closely matched to a subset of TD participants on age, gender, educational background, and verbal ability. Additional TD participants with a broader range of abilities were also tested. Each participant solved sets of verbal analogies and metaphors in verification formats, allowing measurement of both accuracy and reaction times. Measures of individual differences in vocabulary, verbal working memory, and autistic traits were also obtained. Accuracy for both the verbal analogy and the metaphor task was very similar across the ASD and matched TD groups. However, reaction times on both tasks were longer for the ASD group. Additionally, stronger correlations between verbal analogical reasoning and working memory capacity in the ASD group indicated that processing verbal analogies was more effortful for them. In the case of both groups, accuracy on the metaphor and analogy tasks was correlated. A mediation analysis revealed that after controlling for working memory capacity, the inter-task correlation could be accounted for by the mediating variable of vocabulary knowledge, suggesting that the primary common mechanisms linking the two tasks involve language skills.     

Phthalic acid amygdalopetal lesion of the nucleus basalis magnocellularis induces reversible memory deficits in rats

The basolateral amygdala (BLA) is extensively implicated in emotional learning and memory. The current study investigated the contribution of cholinergic afferents to the BLA from the nucleus basalis magnocellularis in influencing aversive learning and memory. Sprague-Dawley rats were given permanent unilateral phthalic acid (300 ng) lesions of the nucleus basalis magnocellularis and were chronically implanted with cannulas aimed at the ipsilateral BLA. Lesioned rats showed a pronounced inhibitory avoidance task retention deficit that was attenuated by acute posttraining infusions of the muscarinic cholinergic agonist oxotremorine (4 ng) or the indirect agonist physostigmine (1 microg) into the BLA. Continuous multiple-trial inhibitory avoidance training and testing revealed that lesioned rats have a mild acquisition deficit, requiring approximately 1 additional shock to reach the criterion, and a pronounced consolidation deficit as indicated by a shorter latency to enter the shock compartment on the retention test. Because lesioned rats did not differ from sham-operated controls in performance on a spatial water maze task or in shock sensitivity, it is not likely that the memory impairments produced by the phthalic acid lesions are due to any general sensory or motor deficits. These findings suggest that the dense cholinergic projection from the nucleus basalis magnocellularis to the BLA is involved in both the acquisition and the consolidation of the aversive inhibitory avoidance task.     

Individual differences in reappraisal ability: Links to reappraisal frequency, well-being, and cognitive control

Reappraisal is generally viewed as an adaptive emotion regulation strategy. Reappraisal frequency has been associated with greater well-being, and reappraisal ability is thought to be composed of several crucial cognitive control processes. However, the relationships among reappraisal ability, reappraisal frequency, well-being, and various cognitive control processes have not yet been determined. In this study, we experimentally examined individual differences in reappraisal ability (RA), and also assessed reappraisal frequency, well-being, and several cognitive control processes. We observed a positive relationship between RA, reappraisal frequency, and well-being. RA was also related positively to working memory capacity and set-shifting costs, and marginally related to abstract reasoning. These findings have important implications for understanding the cognitive components and affective outcomes of RA.     

Does childhood general cognitive ability at age 12 predict subjective well-being at age 52?

Drawing on a broad, multidimensional conceptualization of subjective well-being, this study examined the power of childhood general cognitive ability to predict life satisfaction, satisfaction with eight individual life domains, and the frequency of experiencing positive and negative affect in middle adulthood. Data were obtained from a representative Luxembourgish sample (N = 738; 53% female) in a longitudinal study conducted in 1968 and 2008. Childhood general cognitive ability was unrelated to life satisfaction, negatively related to negative affect and satisfaction with free time, and positively related to positive affect and satisfaction with some of the life domains associated with socioeconomic success (i.e. finances, self, housing, work, or health). This predictive power persisted even when childhood socioeconomic status was controlled.     

Athletes’ ease of imaging predicts their imagery and observational learning use

Objectives

Following the development of the Sport Imagery Ability Questionnaire (SIAQ; Williams & Cumming, 2011), the aim of the present two studies was to more comprehensively examine the relationship between sport-related imagery ability and the functions of imagery and observational learning (OL) athletes report. A second aim was to establish the SIAQ’s predictive validity.

Design

Two samples of cross-sectional questionnaire data are presented in two studies.

Method

For both studies, athletes were recruited from a variety of team and individual sports, ranging in competitive level and years of experience. In Study 1, 117 participants (41 male and 76 female) with a mean age of 24.38 (SD = 9.46) completed the SIAQ and the Sport Imagery Questionnaire (SIQ; Hall, Mack, Paivio, & Hausenblas, 1998). In Study 2, 221 participants (83 male and 138 female) with a mean age of 22.34 (SD = 7.66) completed the SIAQ and the Functions of Observational Learning Questionnaire (FOLQ; Cumming, Clark, Ste-Marie, McCullagh, & Hall, 2005).

Results

Athletes’ imagery ability significantly predicted their imagery and OL use. Moreover, with the exception of performance OL, predictions were stronger when the type of imagery ability closely matched the function of imagery or OL being predicted.

Conclusions

As well as demonstrating the predictive validity of the SIAQ, results from both studies support the need to use imagery ability measures that most closely match the type of imagery or OL being used.
