Stability of WISC-R scores in children with learning difficulties

Student records of 130 children with learning difficulties who had been tested twice were examined to determine the stability of WISC-R scores over time. There were significant losses in Verbal IQ and Full Scale IQ. Subjects in the above-average IQ range had greater losses in Verbal IQ and Full Scale IQ and greater gains in Performance IQ than did those in the below-average IQ range. Children initially tested before age 8 had a significant IQ loss, but those tested after age 8 maintained a constant IQ. The WISC-R is most frequently administered to children with learning difficulties. Results presented here suggest that the IQs in this population are not as stable as was previously thought, and this may provide a rationale for the periodic readministration of the WISC-R.     

Rapid demand curves for behavioral economics

A method for determining the relationship between food consumption and the price of food (demand function) in behavioral economic experiments is described. Although previous methods have generally required as long as 40 days, the present method can generate a complete demand function within 7 days, and therefore may be more suitable for use in the evaluation of drugs, toxins, and physiological/anatomical interventions. Moreover, measures of circadian rhythmicity, post-reinforcement pause durations, and interresponse times can also be generated. Three experiments tested the stability of the method in a variety of procedural manipulations: repeated exposure to the procedure, increasing versus random daily food price, and size of daily changes in food price. The procedure generated demand functions that were similar to those that require more extended testing, and the demand functions were not generally affected by procedural manipulations. Body weight, which can also affect consumption, generally decreases with increases in the price of food; so this variable should be recorded and used as a covariate in analyzing demand functions. With the exception of circadian rhythmicity, the other measures were stable across procedural variations and showed expected changes as a function of food price: postreinforcement pause durations increased as price increased, but interresponse times did not.     

Linking Quality and Quantity of Parental Linguistic Input to Child Language Skills: A Meta-Analysis

This meta-analysis examined associations between the quantity and quality of parental linguistic input and children’s language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of linguistic input. For quality and quantity of parental linguistic input, effect sizes were stronger when input was observed in naturalistic contexts compared to free play tasks. For quality of parental linguistic input, effect sizes also increased as child age and observation length increased. Effect sizes were not moderated by socioeconomic status or child gender. Findings highlight parental linguistic input as a key environmental factor in children’s language skills.     

The Social Ecology of Adolescent Alcohol Misuse

A conceptual framework based on social ecology, social learning, and social control theories guided identification of social contexts, contextual attributes, and joint effects that contribute to development of adolescent alcohol misuse. Modeling of alcohol use, suggested by social learning theory, and indicators of the social bond, suggested by social control theory, were examined in the family, peer, school, and neighborhood contexts. Interactions between alcohol modeling and social bond indicators were tested within and between contexts. Data were from a longitudinal study of 6,544 students, 1,663 of their parents, and the U.S. Census. All contexts were uniquely implicated in development of alcohol misuse from ages 11 through 17 years, and most alcohol modeling effects were contingent on attributes of social bonds.     

Personality Traits of Women in Team Sports vs. Women in Individual Sports

Abstract

The problem under investigation was to determine if were distinguishing personality traits when women who compete in team sports were compared to women who compete in individual sports. The subjects were chosen from a selected group of 156 women AAU athletes and the 1964 United States Olympic team. Those women who agreed to take part in the study were sent a copy of Form A of the Sixteen Personality Factor Questionnaire, which was the instrument used to measure selected personality factors. Differences between groups were analyzed by means of the t test.

The results indicated that women athletes who compete in individual sports rated higher on the personality factors of dominance, adventurousness, sensitivity, introversion, radicalism, and self-sufficiency and lower on the factor of sophistication when compared to women athletes who compete in team sports. No differences were found in the factors of sociability, intelligence, stability, surgency, conscientiousness, suspecting, guilt-proneness, high self-sentiment, or high ergic tension.     

Navigating the Measurement and Monitoring Maze

Assessment of students with disabilities is a critical component of special education. In addition to the complexity of assessment (e.g., high-stakes assessments, progress monitoring, diagnosis), the issue is complicated further by the use of acronyms. This can make both explaining and understanding important information related to students very difficult. Acronyms related to assessment create a virtual alphabet soup that can be confusing for parents, teachers, and school personnel. Assessment acronyms include terms related to both state testing and progress monitoring such as AYP, AA-AAS, AA-MAS, AA-GLAS, RTI, CBA, and CBM. Educators must understand not only the nature and purpose of the various assessments, but they must also be familiar with the assessment acronyms in order to select appropriate assessments to measure the academic progress and performance of students, and to communicate effectively with families and related school professionals. The purpose of this article is to describe common assessments administered in the field of education today as well as to demystify the use of the acronyms related to these assessments and implications for teachers and other educators. Additionally, we point to some resources that can be of value to individuals wishing to establish or expand their repertoires of assessment practices as the current emphasis on progress monitoring continues to unfold.     

Do home numeracy and literacy practices of Greek and Canadian parents predict the numeracy skills of kindergarten children?

Children’s experiences with early numeracy and literacy activities are a likely source of individual differences in their preparation for academic learning in school. What factors predict differences in children’s experiences? We hypothesised that relations between parents’ practices and children’s numeracy skills would mediate the relations between numeracy skills and parents’ education, attitudes and expectations. Parents of Greek (N = 100) and Canadian (N = 104) five‐year‐old children completed a survey about parents’ home practices, academic expectations and attitudes; their children were tested on two numeracy measures (i.e., KeyMath‐Revised Numeration and next number generation). Greek parents reported numeracy and literacy activities less frequently than Canadian parents; however, the frequency of home numeracy activities that involved direct experiences with numbers or mathematical content (e.g., learning simple sums, mental math) was related to children’s numeracy skills in both countries. For Greek children, home literacy experiences (i.e., storybook exposure) also predicted numeracy outcomes. The mediation model was supported for Greek children, but for Canadian children, the parent factors had both direct and mediated relations with home practices.     

Teachers: A Critical But Overlooked Component of Bullying Prevention and Intervention

To complete this special issue on theoretical bases for antibullying efforts in schools, we focus in this article on the importance of teachers and other educators in the ecology of schools. First, we present evidence that teachers are not perceived to be effective at intervening when bullying occurs. Then, using a social motivational lens, we provide an overview of teachers' role as a socializing agent in the classroom and school with a particular emphasis on their influence on bullying behaviors among students. Then we present two theories, the theory of planned behaviors, and the transactional theory of emotions and coping. We believe these theories highlight the complexity of teacher responses and make the case that teachers need more than knowledge of bullying to be effective in their role. We discuss implications for teacher training and professional development.
