Gender differences in children's arithmetic performance are accounted for by gender differences in language abilities

Studies have shown that female children, on average, consistently outperform male children in arithmetic. In the research reported here, 1,556 pupils (8 to 11 years of age) from urban and rural regions in the greater Beijing area completed 10 cognitive tasks. Results showed that girls outperformed boys in arithmetic tasks (i.e., simple subtraction, complex multiplication), as well as in numerosity-comparison, number-comparison, number-series-completion, choice reaction time, and word-rhyming tasks. Boys outperformed girls in a mental rotation task. Controlling for scores on the word-rhyming task eliminated gender differences in arithmetic, whereas controlling for scores on numerical-processing tasks (number comparison, numerosity estimation, numerosity comparison, and number-series completion) and general cognitive tasks (choice reaction time, Raven's Progressive Matrices, and mental rotation) did not. These results suggest that girls' advantage in arithmetic is likely due to their advantage in language processing.     

循证医学教学模式对医学生消化内科实习效果的影响

探讨循证医学教学模式在消化内科临床实习教学中的运用效果.对入科实习的60名本科生,随机分为两组:循证教学模式组和传统教学模式组,每组30人,带教时间均为一个月.结果显示,两组间理论考试成绩比较无明显差异,而循证教学模式组临床答辩成绩与传统教学模式组比较差异有统计学意义(P＜0,05);循证教学模式组在提高学生的学习兴趣和主动性、分析和解决问题的能力及检索文献资料的能力等方面比率高于传统教学模式组(P＜0.01).因此,把循证医学教学模式运用于消化内科临床实习带教中,能提高学生的学习兴趣,增强学生的自学能力以及评判性思维能力.     

基于内科查房会话语料的医生礼貌策略分析

采用录音方式收集50例内科查房语料,用Brown和Levinson的面子理论分析了医患会话中医生的礼貌策略,发现医生使用的积极礼貌策略类型有反馈、称谓、关照和赞誉等,消极礼貌策略主要有弱化、主动两类,且消极礼貌策略使用频率高于积极礼貌策略.分析显示现阶段平等的医患关系尚未完全建立.     

基于概化理论的作假识别量表编制及其作用

基于概化理论,探讨在《大学生心理资本量表》中加入作假识别量表的具体编制过程及其在提升量表信度、效度等方面的作用。通过因素分析验证《作假识别量表》的单维性;通过概化研究,研究其信效度,并嵌入《大学生心理资本量表》进行验证。结果表明：因素分析解释率为55.858%,概化研究结果显示G系数和Φ系数分别为0.825,0.809。因此,《作假识别量表》有很好的信效度,嵌入《大学生心理资本量表》后能有效地识别作假行为和筛选被试。     

Understanding Factors Associated with Bullying and Peer Victimization in Chinese Schools Within Ecological Contexts

We review factors associated with school bullying and peer victimization in the People’s Republic of China (hereafter referred to as China) within the context of Bronfenbrenner (Am Psychol 32:513–531, 1977) ecological systems framework. Bullying and peer victimization are serious problems in Chinese schools, which calls for effective school-based bullying prevention and intervention strategies. However, understanding of this phenomenon has been limited because the majority of the empirical studies have examined individual characteristics (e.g., age, gender), and relatively few Chinese researchers have considered various contexts of the social ecology, such as cultural contexts. We first discuss the definition and prevalence, which is followed by a review of socio-demographic and ecological factors (micro-, meso-, exo-, and macrosystem) that are correlated with school bullying and peer victimization in Chinese schools. Findings from our review suggest that factors at the socio-demographic (age, gender, behavioral/mental health problems), micro- (parents, peers, and teachers), meso- (parents’ involvement in children’s school), exo- (mass media), and macrosystem (emphasis on academic achievement and collectivism vs. individualism) levels can foster or mitigate bullying and peer victimization among children and adolescents in Chinese schools. We then draw implications for assessment, practice, and policy concerning school bullying and peer victimization in China.     

The Olympic Games and the Improvement of Economic Well Being

This paper investigates whether hosting the Olympic Games will improve economic well being of host countries. It is shown that the economic benefits of hosting the Games can last for up to 16 years. The economy of the host country improves after announcement of successful bid. The improvement peaks in the year of the Games and remains significant for 8 years after the Games.     

The impact of self‐confidence on the compromise effect

This research reports an investigation into whether the personality aspect of self‐confidence affects the compromise effect. We hypothesize that highly self‐confident people have greater certainty in making decisions and are more attracted to risk‐taking, which makes them less likely to choose the safe or middle option in a large choice set. The three studies involved are conducted using between‐ and within‐subjects experimental designs. Various product categories are used to generalize the findings. Study 1 looks at purchasing decisions and utilizes three scales of self‐confidence, risk preference, and uncertainty; it demonstrates that consumers with high self‐confidence are less likely to choose a compromise option due to high certainty in their decision‐making. Study 2 discovers that people with low self‐confidence are more likely to choose the middle option in a risky condition than in a nonrisky condition. Study 3 decomposes self‐confidence into general and specific self‐confidence, and reveals that people with low general self‐confidence and low specific self‐confidence are more likely to choose the middle option.     

Psychological and socioeconomic health of community‐dwelling older adults

Different dimensions of health are intertwined. The purposes of this study were: (1) to investigate the psychological and socioeconomic health status of community‐dwelling older adults in Taiwan, and (2) to compare the psychological and socioeconomic health differences among people of different age groups, gender, marital status, and exercise habits. Using stratified random sampling, 384 Taiwanese community‐dwelling older adults were recruited for this survey research. Based on the Health Model of Older Adults, seven constructs were measured: (1) psychological health: sleep quality, emotional health, cognitive functioning, and health promotion behaviors; (2) socioeconomic health: social engagement, social support, and financial status. Results showed that most participants were in a good state of psychological and socioeconomic health, except that 38.02% of them suffered from sleep disruptions, and the majority of them were not involved in any social group, nor engaged in any volunteer work. Young‐old older adults had better psychological and socioeconomic health than middle‐old and old‐old older adults. Male older adults had better psychological health than female older adults; however, they had less social engagement and social support than female older adults. Married older adults and exercisers performed better in most of the psychological and socioeconomic health indicators than single/widowed older adults and non‐exercisers.     

The impact of the opinions of others on variety‐seeking behavior

One reason for consumer variety‐seeking behavior is interpersonal motivation. Building on previous theories, we suggest that the different information types of interpersonal sources influence the variety‐seeking behavior of individuals. Two laboratory experiments are conducted to examine the influence of the opinions of others on such behavior. The results support the author's contention that to derive more enjoyment from a shared product, an individual will make choices congruent with the opinions of others in online information. The managerial implications and study limitations are also discussed.     

Perceptual style and behavioral pattern of individuals with functional gastrointestinal disorders.

The present research examined the perceptual style and coping pattern characterizing individuals with functional gastrointestinal disorders. A matched case-control design was adopted to compare differences among the target group of individuals with functional gastrointestinal disorders (n = 40), a pain control group of individuals with rheumatism (n = 40), and the community control group of healthy individuals (n = 40). Perceptual style was measured by both monitoring and blunting responses to hypothetical stressful situations, and coping pattern was measured by the use of coping strategies in real-life stressful events. Results revealed that participants with functional gastrointestinal disorders differed from their healthy and rheumatic counterparts in having higher monitoring and lower blunting scores and using action-oriented coping strategies regardless of the controllability of stressful situations.
