An Expanded View of Joint Attention: Skill,Engagement, and Language in Typical Development and Autism

This study provides an expanded view of joint attention and its relation to expressive language development. A total of 144 toddlers (40 typically developing, 58 with autism spectrum disorder [ASD], 46 with developmental delay [DD]) participated at 24 and 31 months. Toddlers who screened positive for ASD risk, especially those subsequently diagnosed with ASD, had poorer joint attention skills, joint engagement during parent–toddler interaction, and expressive language. Findings highlight the dynamic relation between joint attention and language development. In the ASD and DD groups, joint engagement predicted later expressive vocabulary, significantly more than predictions based on joint attention skills. Joint engagement was most severely impacted when toddlers did not talk initially and improved markedly if they subsequently began to speak.     

Developmental Precursors of Relational Aggression From Late Childhood Through Adolescence

Relational aggression—a psychological form of aggression—has numerous negative consequences for physical and emotional health. However, little is known about the risk factors that lead youth to engage in relational aggression. Using multimethod data from a longitudinal research of 674 Mexican-origin youth, this study examined the influence of parents, siblings, and peers on the development of relational aggression. Increases in relational aggression from age 10 to 16 were associated with: (a) low levels of parental monitoring and (b) increased association with deviant peers and siblings. These results held across gender and nativity status. The findings suggest that multiple socialization agents contribute to the development of relational aggression. We discuss the practical implications for reducing relational aggression during adolescence.     

The effect of exploratory talk on the development of sentence structure in able writers

This one‐term practitioner research study, conducted with 33 Year 5 children, considers the impact of teaching exploratory talk skills on the learning of the class, with particular consideration of the development of the ability of gifted and talented children to manipulate and control sentence structure to create effect. Beginning with metatalk activities, the class defined new talk rules, putting them into practice in an action‐research project. The study then went on to consider the detailed application of these skills in a focus group of six gifted children. In order to meet with the requirements of a wider study, the impact of this focus group on the learning of the whole class was observed. While many children, both those in the focus group and the wider class, appeared to embrace exploratory talk as a route to independence of the class teacher, some children were more reluctant to engage. The article concludes with an evaluation of the impact of exploratory talk.     

Intellectual self-mutilation

[The] business man is generous to a fault, but one thing he does demand of all teachers and lecturers and journalists: if we're going to pay them our good money, they‘ve got to help us by selling efficiency and whooping it up for rational prosperity? And when it comes to these blab-mouth, fault-finding, pessimistic, cynical University teachers, let me tell you that during this golden coming year it's just as much our duty to bring influence to have these cusses fired as it is to sell all the real estate and gather in all the good shekels we can.

Autism Spectrum Disorders: Neurobiology and current assessment practices

This study reviews recent research related to the neurobiology of Autism Spectrum Disorders (ASDs) an provides an empirical analysis of current assessment practices. Data were collected through a survey of 117 school psychologists. The Childhood Autism Rating Scale (CARS), Gilliam Autism Rating Scale (GARS), and Gilliam Asperger's Disorder Scale (GADS) were the most frequently used measures. Among the less popular, but more intensive instruments, the Autism Diagnostic Observation Schedule (ADOS) appears to be gaining popularity within school‐based evaluations. Generally, respondents approached the assessment of ASDs from a traditional psychoeducational perspective and reported the use of a very narrow range of ASD‐specific instruments. Concerns are raised regarding the inconsistent inclusion of developmental questionnaires, parent/guardian interviews, and medical professionals in the ASD evaluation process. Implications for practice and the training of school psychologists are discussed. © 2008 Wiley Periodicals, Inc.     

Is movement variability important for sports biomechanists?

This paper overviews the importance for sports biomechanics of movement variability, which has been studied for some time by cognitive and ecological motor skills specialists but, until quite recently, had somewhat been overlooked by sports biomechanists. The paper considers biomechanics research reporting inter- and intra-individual movement variability in javelin and discus throwing, basketball shooting, and locomotion. The overview does not claim to be comprehensive and we exclude such issues as the theoretical background to movement and coordination variability and their measurement. We overview evidence, both theoretical and empirical, of inter-individual movement variability in seeking to achieve the same task goal, in contrast to the concept of “optimal” movement patterns. Furthermore, even elite athletes cannot reproduce identical movement patterns after many years of training, contradicting the ideas of motor invariance and “representative” trials. We contend that movement variability, far from being solely due to neuromuscular system or measurement “noise” – as sports biomechanists may have previously supposed – is, or could be, functional. Such functionality could allow environmental adaptations, reduce injury risk, and facilitate changes in coordination patterns. We conclude by recommending that sports biomechanists should focus more of their research on movement variability and on important related topics, such as control and coordination of movement, and implications for practice and skill learning.     

Letter knowledge in parent–child conversations

Learning about letters is an important component of emergent literacy. We explored the possibility that parent speech provides information about letters, and also that children’s speech reflects their own letter knowledge. By studying conversations transcribed in CHILDES (MacWhinney, 2000) between parents and children aged one to five, we found that alphabetic order influenced use of individual letters and letter sequences. The frequency of letters in children’s books influenced parent utterances throughout the age range studied, but children’s utterances only after age two. Conversations emphasized some literacy-relevant features of letters, such as their shapes and association with words, but not letters’ sounds. Describing these patterns and how they change over the preschool years offers important insight into the home literacy environment.     

Africa.com: the self-representation of sub-Saharan nations on the World Wide Web

In a textual analysis of government Web sites of 29 sub-Saharan countries, we evaluate how African nations use the Internet to construct a self-image for the world. Our analysis finds that the sites echo the ongoing struggle over the definition and purpose of the nation-state in relation to a global economy. Rather than representing a variety of domestic concerns, African countries present a “reflected” identity mirroring Western interests. Their governmental Web sites position the nation as a “brand” and construct citizens as exotic Others who can be marketed to foreign investors and tourists. The tensions between primordial loyalties and modernizing ambitions dissipate in favor of branded identities celebrating ethnicities and natural beauty to attract global investments. Moreover, the technological logic and aesthetics of the Internet reinforce the dependence of these texts on Western knowledge production. Our analysis challenges common assumptions of both post-colonial and Internet research.     

USE OF CRITICAL INCIDENTS FOR PLANNING,IMPLEMENTING, AND EVALUATING A TRAINING PROGRAM FOR FOSTER GRANDPARENTS

The authors report the planning, implementation, and evaluation of a training program for foster grandparents employed at a residential diagnostic and treatment center for disturbed children and youth. The training needs were assessed by task and performance analysis procedures, including the use of critical incident technique. A scoring procedure derived values for various responses to a set of problem situations presented to each foster grandparent. The training objectives focused on the role of the foster grandparents in helping their charges to develop socially acceptable behavior. A cognitive problem‐solving strategy was taught by use primarily of role‐modeling and role‐playing methods. The effectiveness of training was evaluated by comparing pretraining scores on a problem situation test with posttraining scores. Foster grandparents who had been highly rated by supervisors on an independent criterion improved with training; the others did not.
