Mirror-drawing skill in children with specific language impairment: Improving generalization by incorporating variability into the practice session

This study aimed to investigate the procedural deficit hypothesis (PDH) in children with specific language impairment (SLI) by using a mirror-drawing task, a sensorimotor adaptation paradigm that does not involve sequence learning and has never before been used in SLI. A total of 30 school-aged children with SLI matched to 30 typically developing (TD) control children had to trace several figures seen only in mirror-reversed view in two practice sessions separated by a one-week interval. Two practice conditions were compared: a constant condition in which children had to trace the same figure throughout the learning trials, and a variable one in which they had to trace different figures in each trial. The results revealed a similar learning pattern between SLI and TD children in both practice conditions, suggesting that initial learning for a non-sequential procedural task is preserved in SLI. However, the children with SLI generalized the mirror-drawing skill in the same way as the TD children only if there was variability in the way the material was trained (variable practice). No significant schedule effects were observed in the control group.     

Repressive coping and cardiovascular reactivity to novel and recurrent stress

Background and objectives: Repressors tend to report less negative emotion and to describe challenges as less stressful, yet tend to exhibit higher rates of cardiovascular disease. While repressive coping has been shown to be associated with exaggerated physiological reactivity to novel stress, we sought to establish if elevated responses persisted across repeated exposure.

Design and methods: In a sample of 86 healthy female adults, a verbal-autonomic response dissociation index of repressive coping was computed. Participants were exposed to two consecutive stress tasks, with analyses based on comparisons of consecutive stress responses.

Results: Analysis of covariance demonstrated significant differences across the study on diastolic blood pressure and cardiac output, as a function of repressive coping. Repressors showed elevated reactions to both stress tasks; however, cardiac output responses to the second task were more muted indicating that repressive coping was associated with successful adaptation to recurrent stress. Nevertheless, repressive copers maintained an exaggerated cardiovascular responses to recurrent stress.

Conclusions: The present study identifies that repressive coping may be associated with increased risk of cardiovascular disease development through elevated cardiovascular reactions to both novel and recurrent stress.     

基于fNIRS的运动执行与运动想象脑激活模式比较

使用《运动想象问卷−修订版》筛选出的30名被试(男女各半), 采用功能性近红外光谱成像技术(fNIRS)监测被试在执行实际举哑铃(男生, 4磅和8磅; 女生, 2磅和4磅)任务和想象举同等重量哑铃任务时, 其大脑皮层氧合血红蛋白浓度的变化。结果发现：男女被试在运动执行与运动想象任务下都激活了主运动皮层; 且运动执行的大脑激活水平高于运动想象。在执行实际运动任务时, 运动强度显著影响大脑皮层血氧浓度的变化, 表现出左半球偏侧化优势; 在执行想象运动任务时, 运动强度没有影响大脑皮层血氧浓度的变化, 且无偏侧化现象。     

A qualitative study of adaptation to the euro in the Republic of Ireland: I. attitudes,the ‘euro illusion’ and the perception of prices

This is the first of two reports of a study using semi‐structured, in‐depth interviews to explore the current and recollected experiences of Irish people for the period before, during, and after the introduction of euro notes and coins (1 January 2002). Twenty‐four adults, 12 males and 12 females, covering a range of ages and educational attainment, were interviewed between October 2002 and February 2003. We found that most had welcomed the new currency initially, though some had felt less positive about it, whilst current experiences were more mixed. People's explanations for their attitudes seemed to focus more on the economic and practical aspects of currency change rather than symbolic meanings. Initially, most had experienced a euro illusion (prices in euros seeming to be more expensive than in punts). However, for most, the strength of the illusion appeared to diminish quite quickly. Nonetheless, current prices were believed to be higher, and many respondents attributed this either directly or indirectly to the change of currency. Although independent evidence found that there had been price increases in certain sectors, it was concluded that perceived price rises were, in part, illusory, and driven by expectations and selective price monitoring.

积极情绪与身心健康关系研究的进展

积极情绪与身体健康、心理健康和社会适应有密切的关系。首先,积极情绪不仅能够降低传染性疾病的感染风险,能够影响非传染性疾病病情、病程及死亡率。其次,积极情绪能够降低个体的心理易感性,使个体更好的应对负性或压力事件。最后,现有的研究表明积极情绪和社会交往存在相互促进的关系。现存的直接效应模型和压力缓冲模型解释了积极情绪直接和间接促进健康的机制。未来的研究还需在研究方法和模型完善等方面进一步改进。     

青少年自主-联结的发展及其与社会适应的关系研究

青春期是个体自主和联结的发展变化最为显著、最为突出的阶段。研究对424名中学生自主和联结的发展状况及其社会适应进行了调查,结果表明：（1）青少年具有高自治高联结、低自主低联结及个体化型三类不同的自主-联结发展水平;（2）三种类别随年龄增长呈现各自不同的发展态势,同时男生在三种类型上人数分布相对较为均衡,女生则较多属于高自治高联结类型;（3）高自治高联结者的社会适应和学业成绩最为理想。     

从中亚东干人语言的变迁看文化适应

文化适应是一个描述民族文化关系的重要概念,它指的是两个或两个以上不同文化体系间由于持续接触、相互影响而造成一方或双方发生的大规模文化变迁。本文透过中亚东干人在不同民族文化的接触中其语言变迁的过程,对人类文化适应这一重要的文化现象进行了考察。笔者认为,东干人学习使用范围较广的其他民族语言的事实,不仅表现出其自身较强的文化适应性,而且反映出一种对本民族成员所需社会文化资源和未来发展机会的积极争取。     

中学教师社会化过程:交互作用视角

本研究以345名教师为研究对象,基于交互作用视角建立框架模型,研究教师社会化前因变量、社会化近端结果和终极结果之间的关系,以揭示教师社会化过程。结果表明:①教师社会化近端结果在组织策略和社会化终极结果之间起部分中介作用,在教师主动策略和社会化终极结果之间起完全中介作用;②同事帮带仅通过促进教师对学校的了解促进教师社会化终极结果;③家长配合一方面直接促进教师工作绩效,另一方面通过角色清晰对社会化终极结果产生积极影响。     

大学生自恋与心理适应的关系研究

西方心理学界对自恋已有大量的实证研究,文章在依托前人研究的基础上,对大学生自恋与心理适应性的关系进行实证研究,结果表明,（1）男女生在自恋方面无差异显著性,在心理适应性方面存在差异显著性。男生的心理适应性均分高于女生。（2）不同系不同专业的学生,自恋方面无差异显著性,心理适应性方面呈差异显著性。（3）自恋与心理适应性的4个因子的关系研究显示,自恋与心理自控力、自信心有关系。
