Cognitive correlates of performance in advanced mathematics

Background. Much research has been devoted to understanding cognitive correlates of elementary mathematics performance, but little such research has been done for advanced mathematics (e.g., modern algebra, statistics, and mathematical logic). Aims. To promote mathematical knowledge among college students, it is necessary to understand what factors (including cognitive factors) are important for acquiring advanced mathematics. Samples. We recruited 80 undergraduates from four universities in Beijing. Methods. The current study investigated the associations between students’ performance on a test of advanced mathematics and a battery of 17 cognitive tasks on basic numerical processing, complex numerical processing, spatial abilities, language abilities, and general cognitive processing. Results. The results showed that spatial abilities were significantly correlated with performance in advanced mathematics after controlling for other factors. In addition, certain language abilities (i.e., comprehension of words and sentences) also made unique contributions. In contrast, basic numerical processing and computation were generally not correlated with performance in advanced mathematics. Conclusions. Results suggest that spatial abilities and language comprehension, but not basic numerical processing, may play an important role in advanced mathematics. These results are discussed in terms of their theoretical significance and practical implications.     

Neural mechanisms underlying the higher levels of subjective well-being in extraverts: Pleasant bias and unpleasant resistance

The present study investigated the neural mechanisms that underlie the higher levels of subjective well-being in extraverts. The impact of extraversion on the human sensitivity to pleasant and unpleasant pictures of diverse emotional intensities was examined. We recorded event-related potentials (ERPs) for highly positive (HP), moderately positive (MP), and neutral stimuli in the pleasant session, and for highly negative (HN), moderately negative (MN), and neutral stimuli in the unpleasant session, while subjects (16 extraverts and 16 ambiverts) performed a standard/deviant categorization task, irrespective of the emotionality of the deviant stimuli. The results showed significant emotion effects for HP and MP stimuli at the P2 and P3 components in extraverts, but not in ambiverts. Despite a pronounced emotion effect for HN stimuli across the P2, N2, and P3 components in both samples, ambiverts displayed a significant emotion effect for MN stimuli at the N2 and P3 components that was absent in extraverts. The posterior cingulate cortices, which connect multiple neural regions that are important in interactions of emotion and extraversion, may mediate the extravert-specific emotion effect for pleasant stimuli. Thus, extraverts are less susceptible to unpleasant stimuli of mild intensity than are ambiverts, while extraverts have an additional enhanced sensitivity to pleasant stimuli, regardless of emotion intensity. Consequently, the decreased threshold for pleasant emotion and the increased threshold for unpleasant emotion might be essential neural mechanisms that underlie the higher levels of subjective well-being in extraverts.     

Constructing Self-Identity: Minority Students’ Adaptation Trajectories in a Chinese University

Researchers have gone beyond identity status and been putting more and more emphases on the dynamic process of identity development and its contextual embeddedness. Study of individual’s adaptation to the multicultural background is a good point of penetration. Because of the differences in regional conditions and cultural traditions, the minority youths who go to university in the mainstream culture would have special experiences and challenges in the development of their self-identities. Semi-structured interview and narrative were used in this research to discover the characteristics of the self-identity constructing processes of Mongolian undergraduates in a Shanghai university context. Their identity constructing process could be divided into three stages: difference-detecting, self-doubting and self-orienting. The main efforts of identity constructing in each stage could all be described as self-exploring and support-seeking. Special contents of internal explorations and sources of support were distinguished at different stages. As relative results, three main types of self-orientation were revealed: goal-oriented, self-isolated and unreserved assimilated. The characteristics of them are quite similar to those of three identity processing styles proposed by Berzonsky, which indicates there are some common elements lying in all self-development processes of adolescences and young adults. Ethnicity and culture could be background and resource or what Côté called identity capital that impacts the special course of self-identity constructing under similar principles. Different attitudes towards and relationships with their own ethnicity and new surroundings separated the three types of students from each other and interacted with the developmental characteristics and tendencies of their ethnicity identifications and self identities. It was found that minority youths’ self-identity constructing was based on their needs of self-value and interacted with their ecological niche constructing. Take ethnicity attachment and ethnicity responsibility as a typical example: the setting up of bi-direction relationship between individuals and their ethnicity (or other identity-related factors) was very important for minority youths to expand and integrate themselves. We also presented in detail our methodological exploring process so as to illuminate the limitation of traditional methods and the necessity and importance of methodological reform. Methodologically, both emic and etic positions were taken, interview and narrative approaches were adopted and individual angle of analysis was kept in the research. They were all proved to be effective to provide insight into the dynamic process of self identity constructing.     

Perceived Breast Development and Adolescent Girls’ Psychological Well-Being

This study, based on U.S. nationally-representative data from the National Longitudinal Study of Adolescent Health (8,593 13–18?year old girls), explored how perceived breast development was related to psychological well-being among adolescent girls including variations by age and race-ethnicity. It was hypothesized that greater breast development would detrimentally influence adolescent girls’ psychological well-being, although these associations were expected to be stronger for younger adolescent girls and for Whites. Results using multivariate regression analyses with robust standard errors showed that greater perceived breast development was associated with lower self-esteem and higher depressive symptoms for 13–15?year old White, African American (for self-esteem only), and Hispanic (for depressive symptoms only) girls. Although perceived breast development was not associated with 16–18?year old girls’ self-esteem, supplemental analyses found that 16–18?year old Asian American and White girls with considerable or little breast development had more depressive symptoms than those with some breast development. Menarche at a younger age, overweight BMI, perceptions of being overweight, and efforts to lose weight explained a substantial portion of these associations. This study shows that greater perceived breast development, particularly if it occurs at a younger age, is a risk factor for poorer psychological well-being among adolescent girls including racial-ethnic minorities.

研究经后路椎管扩大减压术治疗多节段颈椎后纵韧带骨化症的疗效.自2006年8月至2011年8月,采用经后路椎管扩大减压术治疗多节段颈椎后纵韧带骨化症27例,其中男19例,女8例,年龄48岁～82岁,平均63.6岁.手术前后用日本矫形外科学会(JOA)评分判断神经功能:用疼痛视觉模拟评分(VAS)评价颈肩痛程度.结果所有患者均获随访,随访时间为3个月～5年,平均18个月.术后JOA评分为13.3(10～17)分,较术前10.2(5～14)分有显著改善(t＝14.72,P＜0.01).术后症状优良率88.9％.仅2例出现C5神经根麻痹,为一过性.术后颈肩痛VAS评分平均为1.9(1～3)分,较术前5.2(4～6)分明显缓解(t＝14.25,P＜0.01).经后路椎管扩大减压术能使脊髓彻底减压,充分后移,避免C5神经根麻痹,是目前治疗该病的较好方法.     

展开模型和优势模型在职业兴趣测验中的比较研究

该研究调查了展开模型(GGUM)和优势模型(GRM)对职业兴趣测验反应数据的拟合情况,并对展开模型和优势模型两种测验编制方法在职业兴趣测验中进行了比较。结果发现:(1)展开模型的模型拟合情况和测量精度优于累积模型,两种模型对被试能力参数估计的差异主要体现在极端被试上,对兴趣水平极端高的被试,展开模型的估计值更精确;(2)采用展开模型编制的测验在信度上远远高于Likert方法编制的测验,中间区域题目的增加提高了测验的信度,但两种方法在测验的效标关联效度上没有差异。结果表明,在职业兴趣的测量上,展开模型更精确;在职业兴趣测验的编制上,GGUM和Likert法没有差异,反而Likert法具有简便、易懂的优势。     

记忆编码策略对心境一致性记忆的调节作用

情绪对记忆的影响会受记忆编码策略的调节。本研究通过2个实验探讨编码策略对心境一致性记忆的调节作用。实验1和实验2均采用2（编码策略：提取练习策略、重复学习策略）×2（词性：消极词、中性词）的实验设计,分别探讨了不同记忆编码策略对普通大学生（实验1）和非临床抑郁大学生（实验2）心境一致性记忆的影响。结果发现：无论是被成功诱导出抑郁情绪的普通大学生,还是非临床抑郁倾向大学生,使用重复学习策略时回忆出的消极词均显著多于中性词,表现出显著的心境一致性记忆,而使用提取练习策略时回忆出的消极词和中性词没有显著性差异,未表现出心境一致性记忆。实验结果表明,记忆编码策略对心境一致性记忆具有调节作用,提取练习策略能够抑制心境一致性记忆。研究结果指明了心境一致性记忆的边界条件,并对非临床抑郁个体的学习与记忆具有重要的启示。     

青少年留守经历对网络成瘾的影响:病理性互联网使用的认知行为模型视角

基于病理性互联网使用的认知行为模型,本研究考察青少年留守经历对网络成瘾的影响,并检验非适应性认知的中介作用和粗暴养育的调节作用。以525名中学生为被试,采用非适应性认知问卷、粗暴养育问卷和网络成瘾问卷进行测试,结果发现:(1)有留守经历的个体非适应性认知和网络成瘾的程度更高,而且非适应性认知越强,网络成瘾程度越高;(2)留守经历通过非适应性认知的中介作用影响网络成瘾;(3)留守经历对非适应性认知的影响受到粗暴养育的调节。具体而言,经历较多粗暴养育的青少年,留守经历会增加非适应性认知;但是对于经历较少粗暴养育的青少年,留守经历不会对非适应性认知产生影响。本研究的结果表明,青少年留守经历会增强非适应性认知,进而增加网络成瘾的倾向。但是,如果青少年家庭中粗暴养育程度较低,青少年留守经历对非适应性认知的影响就会消失。
