Concurrent and predictive validity of the LET-II for average children

Memory tests, such as the Learning Efficiency Test-II (LET-II), have frequently been used to describe the memory characteristics of special populations such as persons with learning disabilities, brain damage, or Alzheimer's disease. Yet, few research studies have examined the memory characteristics of normally functioning children and compared these characteristics to their performance on ability tests or real-life achievement criteria. This study investigates the predictive and concurrent validities of the LET-II for performance on the Kuhlmann-Anderson Tests (K-A), class grades, and actual grade level functioning in reading and mathematics for third and fourth grade children of average intelligence. The LET-II memory factor scores correlated significantly with the K-A scores, class grades and actual grade level functioning in reading. The relevance of these findings for norm-referenced psychological tests, and in particular memory tests, in real-life settings is examined. © 1996 John Wiley & Sons, Inc.     

Predicting infant outcome in families of employed and nonemployed mothers

Differences in infant outcome, predictor variables, and their relationships were explored as a function of maternal employment. Thirty 18-month-olds and their mothers were studied. Child intelligence, attachment security, and dependency were measured, as well as frequency of stressful events in the mother's life, quality of the parents' marital relationship, frequency of the mother's social contacts, and extent of the mother's emotional and parenting supports. Also included were the mother's ability to cope; satisfaction with emotional, parenting, and child care supports; and role satisfaction. For children of employed mothers, attachment and dependency were negatively correlated; securely attached children showed less dependency behavior. For employed mothers, satisfaction with child care and frequent social contacts predicted secure child attachment. Satisfaction with child care, role satisfaction, and ability to cope were strongly interrelated. For nonemployed mothers, maternal coping predicted attachment security, while frequent social contacts predicted greater child dependency. Predictors of child outcome were highly interrelated for nonemployed mothers, with satisfaction with emotional supports playing a pivotal role. These differences suggest that different models to predict infant outcome in employed and nonemployed mother families may be appropriate.     

The effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy: A systematic review

Although the effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy have been investigated in several studies, the findings are equivocal and the practical implications remain unclear. In an attempt to provide clarity on the topic, we performed a systematic literature search of PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library, and Physiotherapy Evidence Database (PEDro) electronic databases. Six studies were found to have met the inclusion criteria: (a) an experimental trial published in an English-language peer-reviewed journal; (b) the study compared the use of short (≤60?s) to long (>60?s) inter-set rest intervals in a traditional dynamic resistance exercise using both concentric and eccentric muscle actions, with the only difference in resistance training among groups being the inter-set rest interval duration; (c) at least one method of measuring changes in muscle mass was used in the study; (d) the study lasted for a minimum of four weeks, employed a training frequency of ≥2 resistance training days per week, and (e) used human participants without known chronic disease or injury. Current evidence indicates that both short and long inter-set rest intervals may be useful when training for achieving gains in muscle hypertrophy. Novel findings involving trained participants using measures sensitive to detect changes in muscle hypertrophy suggest a possible advantage for the use of long rest intervals to elicit hypertrophic effects. However, due to the paucity of studies with similar designs, further research is needed to provide a clear differentiation between these two approaches.     

巨人的衰落

10年前,几乎所有人都相信网球的未来将被会大力发球的巨人主宰,但现在卡洛维奇和埃斯纳都还是二流选手,这当中到底发生了什么?有人开玩笑说:男子网球有三条铁律。第一,所有时代的伟大选手都有一手漂亮的单反,第二,他们都有一个贤内助(米尔卡?但布里吉特也算吗?),第三,他们都有炮弹发球。这里面听起来比较靠谱的仅仅是发球,作为全世界最好的选手和全世界最高的选手费德勒和卡洛维奇,我们可以拿他们的二十项技术指标做比较,卡洛维奇只有一项技术指标可以超过费德勒,那就是发球,这就使得卡洛维奇有机会在任何时候和费德勒较量一番,这就像拳击手有致命的重拳,网球选手有发球,就有了机会。     

Exploration of the DSM-5’s Autism Spectrum Disorder Severity Level Specifier and Prediction of Autism Severity

ABSTRACT

With the publication of DSM-5, clinical assessment of Autism Spectrum Disorder (ASD) has begun to follow a new dimensional framework which includes new severity specifiers. Little research has explored these severity ratings in comparison to other previously established severity indicators (e.g. ADOS-2 calibrated severity score). The current study compared parent and teacher ratings using the BASC-2 for 43 children and adolescents diagnosed with DSM-5 ASD, to contribute novel information to the BASC literature and to explore the new DSM-5 severity ratings. Linear regression analyses were conducted to determine the extent to which the DSM-5 Social Communication and Restrictive/Repetitive Behavior Severity Ratings (clinician-rated) predicted autism severity based on ADOS-2 calibrated severity scores. Furthermore, linear regressions were conducted to explore whether teacher ratings on the BASC-2 enhance parent ratings. Implications of these preliminary results for the assessment of children and adolescents with ASD are suggested.     

“Blessed”: Musical Talent,Smartness, & Figured Identities

The purpose of this study is to explore smartness and talent as social constructs. Drawing on Holland et al.'s (1998) figured identities, this article explores the figuring of abilities by elucidating the voices of African American high school chorus students. Critical Race Theory (CRT) helps to unpack normalized language and practices that comprise intelligence, talent, and identity construction. The student participants in this study contrasted high school experiences in which they constructed musical and academic identities, describing how smart or talented they were relative to significant others around them. Findings suggest that constructions of musical talent and smartness socially positioned students along race, gender, and class lines. Interpretations of talent and intelligence may impact the curricular options made available to students, their academic identity construction, musical identity construction, and inequitable school practices.
