定量运动负荷和个性特征对动觉准确性和动作稳定性的影响

目的在于了解个性特征和定量运动负荷与同射箭运动员技术水平密切相关的肘关节动觉方位准确性和手动作稳定性的关系。研究结果表明：个性特征对肘关节动觉方位准确性和手动作稳定性的影响不显著;定量运动负荷可以使肘关节动觉方位准确性明显提高,而手动作稳定性变化不显著。本研究初步证明了韩国射箭训练中利用跑步等手段使运动员处于较高心率之下进行射准练习的方法是实用有效的。     

The K-BIT: A screen for IQ in six diverse populations

Performance data were collected on the Kaufman Brief Intelligence Test (K-BIT) from a total of 196 individuals from six diverse populations. College students did best, followed closely by closed head-injured adults and their controls; the order of performance then was learning-disabled children, psychiatric patients, and finally, neurosurgical patients in the acute stages of recovery.     

Placement Stability Following Short-Term Residential Care

Youth discharged from a short-term residential facility and reunified with their parents were contacted at least one year after discharge to determine whether or not they had a disruption in their placement since reunification. Follow-up intervals of 149 youth contacted (82% of the eligible sample) ranged from a minimum of 12 months to a maximum of 30 months post-discharge. Differences in the time to placement disruption were analyzed using survival analysis techniques. After controlling for adjustment differences during the treatment program, youth behavior problems, and family problems, a significant interaction of youth age and treatment intensity was found: Compared to the others, younger youth who received additional treatment components had placement disruptions later and less frequently.     

斯腾伯格(R.J.Sternberg)三重智力理论述评

本文分三部分。一、论述斯氏对传统ＩＱ测验的主要批评。二、介绍三重智力理论,尤以情境亚理论和经验亚理论为重点。三、对三重智力理论的基本评价：它拓宽了智力本质的内涵,为编制较理想的测验提供了较适当的基础,在三重理论的框架内能较好解决测验有效性和测验公平性问题;三重结构本质上是一种层级结构而非平行结构;经验亚理论与或分亚理论之间的关系值得进一步探讨。     

Some relationships between behavioral and traditional assessment

Psychometric principles and procedures were developed within the context of traditional approaches to assessment. In order to illustrate the frequent, if not uniform, applicability of these principles to behavior assessment, we first discuss the differences and similarities between traditional and behavioral assessment. We then point out ways in which, given the nature of behavior assessment, attention to certain psychometric principles and procedures would expedite the development of more adequate behavior assessment devices and procedures.     

Developmental changes in inspection time: what a difference a year makes

This paper provides a partial replication and extension of a classic longitudinal study by Nettelbeck and Wilson [J. Exp. Child Psychol. 40 (1985) 1] that compared the relative influence of maturation and task experience on developmental changes in inspection time (IT). In the study reported in this paper 226 children aged between 6 and 9 were tested on an IT task in Year 1 and immediately retested to assess the importance of task familiarity. They were also retested 1 year and 2 years later. Counter to Nettelbeck and Wilson's conclusion, analyses of these data comparing the relative difference made by age maturation and by task experience revealed that task experience has a much bigger effect on children's IT than maturation. The implications of this for wider theoretical interpretations of the relationship between IT and development are discussed.     

Applying Continuity Theory to Older Adult Friendships

Continuity theory provides a rationalization for understanding older adult friendships. Older adults do not have to anticipate disengagement but can exercise their choice to actively participate in establishing and maintaining friendship structures. The role of friend is one a person can choose to maintain. Friendships are dynamic and progress on a continuum with beginnings, periods of endurance and change, and endings. Continuity theory provides ways to understand why particular people have developed and adapted distinct friendship and social support networks. This insight provides social service professionals, gerontologists, and family members ways to enable older adults to remain in their communities longer and maintain support stability.     

The association of childhood intelligence with mortality risk from adolescence to middle age: Findings from the Aberdeen Children of the 1950s cohort study

There is growing evidence that childhood IQ is inversely associated with mortality in later life. However, the specificity of this association in terms of causes of death, whether it is continuous over the whole range of IQ scores and whether it is the same according to age and sex is not clear. In a large cohort (N = 11,603) of a complete population of children born in one city in the UK in the early 1950s, IQ measured at age 7 years (using a routinely administered picture test) was found to be inversely associated with mortality between the ages of 15 and 57 years. For every 1 SD increase in IQ at 7, the all cause mortality hazard ratio was 0.79 (95% CI 0.73, 0.85). On adjustment for a range of perinatal factors, father's social class at birth, number of sibs in the household and childhood height and weight, this was attenuated slightly to 0.81 (0.74, 0.88). Almost identical associations of IQ with mortality were seen for men and women as well as at younger (15–39) and older (40+) ages. These associations were across the entire IQ range, although some of the high mortality in the lowest category of IQ (< 70) was accounted for by causes associated with congenital disorders. Overall, external causes of death showed the strongest association, with weaker associations being seen for cancer. Further work is required to understand the mechanisms whereby childhood IQ has such a robust association with mortality in later life.     

The Crystallization of Contemporary Racial Prejudice across the Lifespan

The conventional wisdom is that racial prejudice remains largely stable through adulthood. However, very little is known about the development of contemporary racial attitudes like symbolic racism. The growing crystallization of symbolic racism through the lifespan is tested using two data sets that measure the stability, consistency, and predictive validity of symbolic racism in samples ranging in age from young adults to the elderly. The results provide evidence that the crystallization of symbolic racism generally takes on a curvilinear trajectory across the lifespan, showing that it is already largely crystallized by voting age, that it continues to crystallize still further through adulthood and that it begins to decline in coherence in late adulthood. The results generally provide evidence confirming early speculations of symbolic racism theorists concerning the crystallization of symbolic racism across the lifespan and are discussed in terms of different theoretical perspectives on the relationship between aging and attitudes more generally.
