The Effects of Early English Learning on Auditory Perception of English Minimal Pairs by Taiwan University Students

Auditory perception of English minimal pairs was tested with or without noise background. Each subject was interviewed after the test to collect information regarding their early experience on learning English as a foreign language. This study was designed to examine the differential effects of learning English at three age-starting points and two learning durations. This study hopes to determine how childhood experience of English learning (which is not mandatory in public elementary schools) has affected the auditory competence of university students in distinguishing English minimal pairs. Results showed that age effects were salient only under condition of noise background. Without the interference of background noise, most subjects performed well enough to obliterate any potential differences.     

Age and responding-hand related changes in performance of neurologically normal subjects on the line-bisection and chimeric-faces tasks

This study investigated age and responding-hand (left, right, and bimanual) related changes in visuospatial attention. Two tasks were completed by 107 neurologically normal right-handed subjects ranging in age from 5 to 70 years and distributed across four age groups. Task-specific differences between groups were apparent. In the line-bisection task, the younger and older groups displayed symmetrical neglect while the young and middle groups displayed pseudoneglect. In the chimeric-faces task the leftward bias was less pronounced in the older group and more susceptible to responding-hand effects in the middle and older groups. Whilst results, especially those of the bimanual method, provided strong support for an activation model, they imposed an age limitation on its appropriateness as an explanation for performance on the chimeric-faces task. Results are discussed as reflecting changes in the corpus callosum and right hemisphere.     

Why are unemployed aged fifty and over less likely to find a job? A decomposition analysis

Reemployment chances for unemployed aged fifty and over are low compared to those of younger persons. To explain the different chances, the job search literature has largely focused on the job search behavior of unemployed individuals. Based on job search models, we propose that not only job search behavior, but also wage setting behavior, attitudinal variables and personal variables impact the difference in reemployment opportunities. Besides gaining insight into which variables explain the difference in reemployment opportunities, we also test how much of the difference each of these variables explains. We do this by drawing on a decomposition analysis. Using data from 647 recently unemployed, we find that about one third of the reemployment gap can be explained by the variables suggested by job search models, mostly in terms of age differences in search behavior, educational levels and reservation wage. Hence, about 70 % can be ascribed to other factors, such as employer preferences for those aged between 18 and 49. Implications of these results for theory, policy and practice are discussed.     

Prehension in children and adults: The effects of object size

Studies of visually goal-directed arm movements in adults have shown that various task constraints such as intention, context, and object properties affect different kinematic characteristics of the movement components (Jeannerod, 1984; MacKenzie et al., 1987; Marteniuk et al., 1987, 1990; Paulignan et al., 1991; Soechting, 1984). The purpose of the present study was to compare the effects of varying object size on the kinematics of reaching and grasping in both children and adults. Five children aged 9–10 years and five adults aged 18–24 years reached for and grasped three different sized cubes. Results revealed that object size had the same effect on the planning and control of reaching and grasping movements in children as in adults. Unlike adults, however, children in this age range spent more time in deceleration and reached peak aperture much later in the movement trajectory. The results were interpreted as immature integration of the visual and proprioceptive systems in 9–10 year olds. The implications of these findings for further examining developmental trends in prehension are discussed.PsycINFO classification: 2330     

Psychometric Properties of the French Version of the Pictorial Scale of Perceived Movement Skill Competence for Young Children (PMSC)

ObjectiveThe objective of this study was to examine the psychometric properties of a French version of the pictorial scale of Perceived Movement Skill Competence for Young Children (PMSC), which is aligned with the third version of the Test of Gross Motor Development.MethodA sample of 219 French-speaking Canadian children (5 to 12 years old) participated in this study.ResultsResults supported the factor validity and reliability of a 13-item version of the PMSC encompassing two factors (i.e., ball skills and locomotor skills). Subsequent analyses supported the weak, partial strong, and partial strict invariance of responses to the PMSC as a function of sex. Additionally, analyses revealed that boys displayed significantly higher perceived ball skill competence than girls. Results also supported a lack of differential item functioning (DIF) and latent mean differences as a function of body mass index and physical activity/sport involvement, but revealed evidence of DIF and latent mean differences as a function of age. More precisely, these results show that older children displayed significantly: (a) higher scores on the sliding item and lower scores on the kicking item relative to younger children; and (b) lower scores on perceived locomotor skills competence than younger children.ConclusionOverall, results suggest that the French version of the PMSC has acceptable psychometric properties and can be confidently used in research or practice to assess children's perceived movement skill competence.     

The importance of impaired physical health and age in normal cognitive aging

The objective of this study was to investigate the importance of impaired physical health and age in normal cognitive aging. In our cross-sectional, clinical and explorative study, medical and neuropsychological data from 118 voluntary healthy controls aged 26-91 years were collected from five recruitment occasions. Health was assessed according to a criterion reflecting clinical and subclinical severity. The examinations included a clinical investigation, brain neuroimaging, and a comprehensive neuropsychological assessment. Regression analyses showed a significant incidence of clinical and subclinical medical disorders that explained 10.8% of the variation in cognitive performance, while age-related impairment explained 5.6%. Findings of the central nervous system were important but various other medical findings explained about half of the health-related variation. Cognitively demanding tasks were more susceptible to impaired physical health while tasks comprising salient motor- and visual spatial elements were more prone to be impaired by age. Our findings suggest (1) that impaired physical health is more important than chronological age in accounting for cognitive impairment across the adult lifespan, (2) that age and health dissociate with regard to cognitive functions affected, and (3) that selection for so-called "super healthy" elderly people might be justified in cognitive research. Because the prevalent diseases in normal aging are potentially preventable, the present findings promise good prospect for prevention of future cognitive disability among elderly people.     

Protean and boundaryless careers: A study on potential motivators

This paper conceptually links hypothesized scales of the Motivation Questionnaire (SHL (1992). Motivation questionnaire: Manual and users’ guide. Thames Ditton: SHL) to the underlying dimensions of the protean (values-driven and self-directedness) and boundaryless career (physical and psychological mobility) attitudes. Results of regression-analyses (N = 13,000) confirmed most of the hypotheses in terms of the influence of gender, age, education, and managerial experience on motivators linked to the underlying dimensions. A cluster analysis that was conducted to explore how many profiles can be observed when matching work motives to the protean and boundaryless careers, resulted in four motivational groups (Protean career architects, Trapped/lost, Hired/hired hand, and Curious/wanderer). The clusters are discussed in light of the current career literature and provide empirical support for the latest theorizing about the protean and boundaryless career models. Managerial implications and directions for future research are offered.     

Age,Emotion Regulation Strategies,Temperament, Creative Drama,and Preschoolers' Creativity

Based on Yeh's (2004) Ecological Systems Model of Creativity Development, this study investigated the effects that age, the use of emotion regulation strategies, temperament, and exposure to creative drama instruction have on the development of creativity among preschool children. Participants were 1164‐ to 6‐year‐old preschool children. This study categorized the emotion regulation strategies used by preschool children and developed a creativity test which includes the measurement of usefulness, an indicator of creativity that has, until now, been ignored. The main findings are that (a) 6‐year‐olds outperform 4‐ and 5‐year‐olds in terms of creativity; (b) emotion regulation strategies as well as a positive temperament have positive effects on children's creativity; (c) creative drama instruction contributes to children's creativity; and (d) age group, emotion regulation strategies, temperament, and creative drama instruction can collectively predict children's creativity.     

论雅斯贝尔斯“轴心时代”观念的中国思想来源

雅斯贝尔斯对“轴心时代”文明之梳理,在很大程度上是考察在人类历史上中国、印度和希腊三种文明是以何种方式达到“统摄”（das Umgreifende）的。而孔子和老子的思想在达至终极真理的方式方面,给予了雅斯贝尔斯以极大的启发。本文考察了中国资源在雅斯贝尔斯“轴心时代”观念形成过程中所起的作用,并进而指出,如果没有中国思想参与的话,“轴心时代”这一概念会不会出现,都是值得考虑的。反过来,正是借助于作为存在哲学大师的雅斯贝尔斯的复述,孔子和老子的思想变得鲜活起来,从而更符合时代的要求。实际上,中国只是雅斯贝尔斯寻求世界文明历史发展进程的一个重要组成部分,他希望通过对世界不同文明发展进程的探寻,来思考和揭示人性存在的现状,进一步发现共同的起源和未来,从而为他的世界哲学理念提供一个更加广泛的基础。     

Time perception and time perspective differences between adolescents and adults

The present experiment aimed to investigate the differences in time perception and time perspective between subjects representing two developmental stages, namely adolescence and middle adulthood. Twenty Chinese adolescents aged 15–25 and twenty Chinese adults aged 35–55 participated in the study. A time discrimination task and a time reproduction task were implemented to measure the accuracy of their time perception. The Zimbardo Time Perspective Inventory (Short-Form) was adopted to assess their time orientation. It was found that adolescents performed better than adults in both the time discrimination task and the time reproduction task. Adolescents were able to differentiate different time intervals with greater accuracy and reproduce the target duration more precisely. For the time reproduction task, it was also found that adults tended to overestimate the duration of the target stimuli while adolescents were more likely to underestimate it. As regards time perspective, adults were more future-oriented than adolescents, whereas adolescents were more present-oriented than adults. No significant relationship was found between time perspective and time perception.
