Stress and happiness among adolescents with varying frequency of physical activity

The aim of this cross-sectional study was to investigate associations between physical activity, stress, and happiness, as well as possible sex and age differences on these variables in a survey of 1,508 adolescent pupils (13 to 18 yr.) in middle Norway. Adolescents who reported they participated in physical activity 2 to 3 times per week or more scored significantly lower on stress and higher on happiness than those who participated in physical activity 1 day per week or less. There was no significant difference on stress and happiness between those being physically active 2 or 3 times a week and those being active almost every day. There was no sex difference in physical activity frequency. Girls had higher mean scores on stress, and boys scored higher on happiness. Adolescents 15 to 16 years old showed higher stress scores than those 17 to 18 years old, but there were no significant differences between the different age groups when looking at happiness and physical activity. A statistically significant two-way interaction of sex by age was found on both stress and happiness.     

内-外群体偏爱的内隐效应实验研究

本研究以地域刻板印象和地域内一外群体偏爱的两种IAT为实验材料和测量工具,通过它们之间的相关研究进行实验。研究表明：刻板印象和内群体偏爱的内隐效应明显地存在;上海人的内隐效应大于外地人,外地人仍具有一定的内隐效应但也显示具有一定的内隐偏爱;上海人与外地人存在着内群体偏爱,值得注意的是外地人还有一定的对弱势的认同,具有外群体偏爱;实验证明我们设计的IAT纸笔测验版本是可行的,优点是高效、经济、方便和实用。

该文介绍了一种新的等值方法一核等值法。首先介绍了核等值法的研究过程、它的主要特点以及五个步骤（前平滑处理、估计分数概率、连续化、等值、计算等值标准误）。之后,介绍了核等值法与其他传统的观察分等值方法的差异,最后是对核等值法的评价。     

预警、重复学习和反馈对错误记忆的影响——错误记忆的信号检测论分析

本研究用信号检测论分析预警、重复学习和反馈三种变量对错误记忆的影响.实验1考察预警指导语的影响.实验2考察重复学习和反馈的影响.结果表明:预警对被试辨别力和反应偏向的影响不明显,对错误记忆影响也不显著;重复学习不能明显影响被试的反应标准,但可提高辨别力减弱错误记忆;反馈明显使被试倾向于使用更为宽松的反应标准,难以降低错误记忆.再认双加工模型和激活/监测理论能对实验结果做出合理的解释.     

学业成就中等生和优良生的成就目标、自我监控与学业成绩关系的比较研究

采用量表法对学业成就中等生的研究发现：与学业优良生相比,学业成就中等生的自我监控水平显著低下;成就目标与学业成绩并无直接关系,但学习目标会通过自我监控间接影响学业成绩;在学业成就中等生中,高学习目标、低成绩目标者表现出更高的自我监控水平。     

Parents’ Perceptions of Autism Spectrum Disorder Etiology and Recurrence Risk and Effects of their Perceptions on Family Planning: Recommendations for Genetic Counselors

Knowledge about the etiology of Autism Spectrum Disorders (ASDs) is increasing, but causes remain elusive for most cases. Genetic counselors are positioned to help families that have children with ASDs despite uncertainty regarding etiology. To determine how genetic counselors might best provide services, an anonymous survey was conducted with 255 parents whose children were diagnosed on the autism spectrum. Questions concerned: 1) their perceptions of ASD cause(s) and 2) recurrence risk, 3) whether perceived risk affected family planning decisions, 4) whether parents had received genetic services, and 5) how genetic counselors might assist families. The most prevalent perceived cause was genetic influences (72.6%). Most parents’ recurrence risk perceptions were inaccurately high and significantly affected family planning. Only 10% had seen a genetic professional related to an ASD. Parents provided several suggestions for genetic counselor best practices. Findings indicate the importance of genetic counselor awareness of parent perceptions in order to best help families who have children with ASDs.     

A Comparative Analysis of Ethical and Professional Challenges Experienced by Australian and U.S. Genetic Counselors

Ethical issues are an inevitable part of genetic counseling practice. Prior research identified 16 domains of ethical and professional challenges encountered by practitioners in the United States. In order to further validate these domains, the present study surveyed Australian genetic counselors. Sixty-three respondents rated the frequency with which they encountered each domain, and 39 individuals also provided personal anecdotes detailing their most challenging ethical and professional dilemmas. Every domain reportedly was experienced by the Australian sample. However, there were some differences between Australian respondents and U.S. genetic counselors in frequencies of domain occurrence, and in strategies recommended for resolving them. Several anecdotes illustrate challenging situations due to Australia’s geography, universal healthcare system, and the genetic counseling profession’s evolution in that country. The results generally validate domains identified for U.S. genetic counselors. They further suggest that certain ethical issues may manifest in ways unique to a given country, and therefore they must be addressed in a culturally-appropriate manner.

Tasteful Solutions: Solution-Focused Work with Groups of Immigrants

Solution-focused family therapy is well established as a method in the therapeutic field. Less is written regarding solution-focused thinking and practice in preventive work, providing health information. Informed by the work of Insoo Kim Berg and Steve de Shazer, a workshop of primary health care was established in an inner city area of Oslo, Norway in 1994 with a major task of developing methods for providing information about health issues for immigrants as well as the native population. Results from an evaluation of this work are presented and some issues are related to empowerment work and especially Paulo Freires' liberating dialogue.     

Modulating the phonological similarity effect: The contribution of interlist similarity and lexicality

The classical phonological similarity effect (PSE) was studied with words and nonwords in two immediate serial recall (ISR) tasks. The relative contributions of intralist and interlist interference were compared, and differential effects on item and order memory were observed. PSE occurred with words and was reversed with nonwords. In addition, PSE was modulated by interlist similarity, which enhanced recall of rhyme items and impaired recall of distinct items. Finally, interlist similarity reduced item recall of words, whereas it improved serial recall of nonwords. The latter finding rules out the hypothesis that the reverse PSE for nonwords is due to interlist interference. It is concluded that two opposing effects of phonological intralist similarity cause the interaction between PSE and lexicality in ISR. With words, the positive effect on item recall is usually masked by a much more disruptive effect on position accuracy. With nonwords, however, the positive effect often masks the negative one. These findings are discussed in relation to current models of verbal short-term memory.
