Limb Dominance and Its Effects on the Benefits of Intralimb Transfer of Learning: A Visuomotor Aiming Task

Research has attempted to address what characteristics benefit from transfer of learning; however, it is still unclear which characteristics are effector dependent or independent. Furthermore, it is not clear if intralimb transfer shows, similarly to interlimb transfer, an asymmetry of benefits between the upper limbs. The purpose of the current study is to examine if effector independence effects emerge, as observed in interlimb transfer studies, when transfer to new effector group within the same limb occurs, and whether the pattern of intralimb transfer benefits differ between the limbs. Our results suggest that a visuomotor task transfers within both limbs, even though the transfer benefits within the limbs seem to differ. This was supported by more transfer occurring in the dominant limb than the nondominant limb. Potential control mechanisms used for intralimb transfer are discussed.     

Eye–voice span during rapid automatized naming of digits and dice in Chinese normal and dyslexic children

We measured Chinese dyslexic and control children's eye movements during rapid automatized naming (RAN) with alphanumeric (digits) and symbolic (dice surfaces) stimuli. Both types of stimuli required identical oral responses, controlling for effects associated with speech production. Results showed that naming dice was much slower than naming digits for both groups, but group differences in eye‐movement measures and in the eye–voice span (i.e. the distance between the currently fixated item and the voiced item) were generally larger in digit‐RAN than in dice‐RAN. In addition, dyslexics were less efficient in parafoveal processing in these RAN tasks. Since the two RAN tasks required the same phonological output and on the assumption that naming dice is less practiced than naming digits in general, the results suggest that the translation of alphanumeric visual symbols into phonological codes is less efficient in dyslexic children. The dissociation of the print‐to‐sound conversion and phonological representation suggests that the degree of automaticity in translation from visual symbols to phonological codes in addition to phonological processing per se is also critical to understanding dyslexia.     

Two Concepts or Two Approaches? A Bifactor Analysis of Psychological and Subjective Well-Being

Researchers often debate about whether there is a meaningful differentiation between psychological well-being and subjective well-being. One view argues that psychological and subjective well-being are distinct dimensions, whereas another view proposes that they are different perspectives on the same general construct and thus are more similar than different. The purpose of this investigation was to examine these two competing views by using a statistical approach, the bifactor model, that allows for an examination of the common variance shared by the two types of well-being and the unique variance specific to each. In one college sample and one nationally representative sample, the bifactor model revealed a strong general factor, which captures the common ground shared by the measures of psychological well-being and subjective well-being. The bifactor model also revealed four specific factors of psychological well-being and three specific factors of subjective well-being, after partialling out the general well-being factor. We further examined the relations of the specific factors of psychological and subjective well-being to external measures. The specific factors demonstrated incremental predictive power, independent of the general well-being factor. These results suggest that psychological well-being and subjective well-being are strongly related at the general construct level, but their individual components are distinct once their overlap with the general construct of well-being is partialled out. The findings thus indicate that both perspectives have merit, depending on the level of analysis.     

Adult Children’s Caregiver Burden and Depression: The Moderating Roles of Parent–Child Relationship Satisfaction and Feedback from Others

The issue of elderly care has generated great interest because today, most of us live in an aging society. It has been found that caring for one’s elderly parents is a stressful experience that is related to negative outcomes. In addition, accompanied with the decline in fertility may make adult children feel heavier caregiver’s burden. Therefore, the current study investigates moderators that may help reduce the caregiver burden. Following the conservation of resources theory (COR), we hypothesized that feedback from others and a good parent–child relationship serve as resources that may help the individual manage the stress associated with caring for his or her elderly parents. To examine our hypotheses, we collected data from 502 adult children who were primary caregivers for their elderly parents. All participants completed the Burden Assessment Scale (BAS), the Center for Epidemiological Studies Depression Scale (CES-D), the Feedback from Others Scale, and the Parent–Child Relationship Satisfaction Scale. Supporting our prediction, we found a positive correlation between the caregiver’s burden and the caregiver’s levels of depression. Furthermore, both moderation effects were significant. Consistent with our hypotheses, the relationship between caregiver burden and his or her level of depression was weaker when participants had high feedback from others or had a better parent–child relationship. Our findings highlight the view that possessing more resources may help the individual manage the stress associated with caring for elderly parents. Implications for issues related to elderly care are discussed.     

北京学生对日刻板印象及3·11地震后的情绪和援助意向研究

研究采用问卷法探讨了北京市大中小学生对日本人的刻板印象差异、日本3·11地震后情绪与援助意向的不同,以及刻板印象和情绪反应对于其援助意向的影响,结果发现:(1)北京市大中小学生对日本人的总体刻板印象偏消极,但高中生和大学生在能力维度表示了一定程度的肯定;(2)日本3·11地震后,大中小学生整体的情绪反应程度不强;但高中生和大学生较之小学生和初中生表现出更多的悲伤、同情等亲社会情绪,而更少幸灾乐祸情绪;(3)大中小学生在是否对日本进行援助的问题上显得比较保守;(4)对日本人的刻板印象与地震后的情绪反应和援助意向之间存在显著相关;(5)各群体中,亲社会情绪在对日本人的刻板印象和地震后的援助意向之间起部分中介作用;但对地震本身的事件应对情绪并不存在这种中介效应.结论:北京市大中小学生对日本人的刻板印象较为消极,其对3·11地震后援助倾向有显著影响,且这种作用部分是通过亲社会情绪产生的.     

神经质人格迫选量表的开发及其抗作假效果研究

传统的迫选量表得分是自模式数据,最近提出的Thurstone IRT模型建构了被试对迫选量表反应的数学模型,能够更精确地度量被试的特质水平.研究自编了神经质人格迫选量表,与常用的测量神经质的Likert量表一起,在无压力、模拟应聘和实际应聘三种情境下进行施测.结果发现,迫选量表的实测数据能够较好地拟合Thurstone IRT模型,该模型估计的特质得分不具有自模式数据的性质,比传统计分更能够抵抗作假.无论采用哪种计分方式,迫选量表都比Likert量表更能够抵抗作假.     

恐惧情绪加工的神经机制

恐惧是一种基本情绪,在人类的生存和适应中具有重要意义.研究者认为对恐惧情绪的加工存在着两种方式——阈上加工和阈下加工,而最近更多的研究者认为对恐惧的加工是需要中枢神经系统参与的阈上加工.在恐惧的形成与表达中,杏仁核、前扣带回、眶额叶皮质等脑区发挥着重要的作用;恐惧记忆的编码与巩固受到海马和各相关脑区的共同影响;前扣带回、内侧前额叶皮质等相关脑区是恐惧情绪调节的高级中枢;在恐惧的消退过程中,内侧前额叶发挥着重要的作用,它影响杏仁核、海马等相关脑区的活动.未来研究应该从恐惧情绪加工过程中脑区的交互机制、恐惧易感性以及发展认知神经科学等角度对恐惧神经机制展开大量研究,力图全方位地理解恐惧加工的神经机制.     

Institutional and Personal Adjustment in Old Age

Assertive behaviors, as measured by teachers, observers, and an experimental task, were related to each other and to Stanford-Binet intelligence scores. All measures of assertion were correlated with each other and with total IQ. Subsequent item analysis of the Binet showed that the more assertive children did better on certain items: comprehension, verbal, and discrimination. These results are discussed as are possible reasons for non-responsiveness of 20% of the sample and the implications of this for future research.     

Big-five personality and BIS/BAS traits as predictors of career exploration: The mediation role of career adaptability

Based on career construction theory, the current research examined whether career adaptability mediates the relations of the personality traits (Five-Factor Model personality traits and behavioral inhibition and activation systems (BIS/BAS)) to career exploration behavior. Results from a survey in Chinese university students (N = 264) showed that career exploration correlated negatively with neuroticism, and positively with openness to experience, extroversion, agreeableness, conscientiousness and BAS. Results of regression analyses further showed that openness to experience, agreeableness, conscientiousness and BAS served as the strongest predictors for career exploration. In addition, career adaptability was shown to be a key mediator for the relationships between personality traits and career exploration behavior. Career concern and career curiosity were the more important dimensions in the mediation model. These findings advance current understandings on how different personality traits predict career exploration behavior.     

A Discussion on Governmental Research Grants

Governmental research grants are financially supported by taxpayers to meet financial requirements of research, particularly research that is unlikely to be supported by private funds. Researchers reward donors by producing knowledge. Publishing research results in an academic journal reflects achievement by researchers; however, receiving a grant award does not. The latter only provides the researcher with the capacity to perform his/her research. Applicants may receive more financial support than they actually need because there is no strict audit on the amount of money requested by each research proposal. There are fewer opportunities to apply for a governmental grant than there are for publishing an academic article, and the application process for governmental grants is not flexible. Some potentially innovative research may be impeded by the intense competition among scientific researchers applying for financial support. Researchers face stiffer competition at this stage than at the stage of publishing results. This paper suggests that scientific foundations can improve their efficiency by giving funding preference to economic proposals. Methods for estimating the efficiency of grants are proposed. The practice followed by the Small Grants for Exploratory Research programme of the National Science Foundation validates my analysis and recommendations.
