The effects of the constancy of location and order in working memory visual–phonological binding of children with dyslexia

It has been suggested that children with dyslexia have difficulties in visual–phonological working memory (WM) binding, supporting the hypothesis that this ability is crucial in the formation of associations between written forms and phonological codes required by reading. However, research on this topic is currently scarce and has not clarified to what extent binding may be supported by spatial and temporal information. The present study examined visual–phonological WM binding performance in a group of children with dyslexia compared to a control group of typically developing children matched for age, gender, and grade. Children had to memorize ephemeral associations between meaningless shapes and nonwords, with stimuli presented in either fixed or variable spatial locations, and in either fixed or variable temporal order across trials; performance was assessed using a recognition task. Results showed that children with dyslexia have a deficit in visual–phonological WM binding in every presentation condition and that, unlike control children, they are not able to use fixed spatial locations as an aid to bind information. Crucially, however, children with dyslexia still benefit from the presentation of stimuli in a fixed temporal order. These findings support the hypothesis that a WM binding deficit is crucial in children with dyslexia, and have potential implications for treatment strategies.     

Managing diversity in organizations: An integrative model and agenda for future research

The literature on policies, procedures, and practices of diversity management in organizations is currently fragmented and often contradictory in highlighting what is effective diversity management, and which organizational and societal factors facilitate or hinder its implementation. In order to provide a comprehensive and cohesive view of diversity management in organizations, we develop a multilevel model informed by the social identity approach that explains, on the basis of a work motivation logic, the processes by, and the conditions under which employee dissimilarity within diverse work groups is related to innovation, effectiveness, and well-being. Building on this new model, we then identify those work group factors (e.g., climate for inclusion and supervisory leadership), organizational factors (e.g., diversity management policies and procedures, and top management's diversity beliefs), and societal factors (e.g., legislation, socioeconomic situation, and culture) that are likely to contribute to the effective management of diversity in organizations. In our discussion of the theoretical implications of the proposed model, we offer a set of propositions to serve as a guide for future research. We conclude with a discussion of possible limitations of the model and practical implications for managing diversity in organizations.     

Statistical equating with measures of oral reading fluency

Recent research on curriculum-based measurement of oral reading fluency has revealed important issues in current passage development procedures, highlighting how dissimilar passages are problematic for monitoring student progress. The purpose of this paper is to describe statistical equating as an option for achieving equivalent scores across non-parallel reading passages. The psychometric and design properties of words-correct scores are examined, and the requirements of traditional equating methods are discussed. Simulated and empirical words-correct scores are used to demonstrate the steps in the equating process and the situations in which each method is most appropriate.     

SPECIAL SERIES: Intensive Cognitive-Behavioral Treatments for Child and Adolescent Anxiety Disorders

Cognitive-behavioral treatments are efficacious intervention choices for anxious youth, yet the lack of access to and usage of evidence-based treatments outside of a research context continues to challenge efforts to disseminate and implement such interventions. One potential avenue for reconciling effective care and that most readily accessed by children and their families may be to offer treatment in an intensive format, typically consisting of a more concentrated dose of cognitive-behavioral treatment components. This special series in Cognitive and Behavioral Practice aims to explore the evolution of intensive cognitive-behavioral treatments currently under investigation across a variety of child and adolescent anxiety disorder populations, including specific phobias, obsessive-compulsive disorder, separation anxiety disorder, school refusal, and panic disorder. In addition to delineating the research support to date for intensive cognitive-behavioral treatment among children and adolescents with anxiety disorders, the articles included in this series provide detail on the application of each intensive intervention, highlight innovative treatment elements, and explore clinical and systematic issues unique to an abbreviated treatment format.     

Methodological Strategies in Child Clinical Trials: Advancing the Efficacy and Effectiveness of Psychosocial Treatments

The present paper reviews issues of treatment efficacy (i.e., potency) and effectiveness (i.e., clinical utility) in applied clinical child research. Threats to treatment evaluation are reviewed in the context of these two dimensions. It is proposed that treatment outcome research faces new challenges stemming from the ever increasing emphasis on generalization of gains and dissemination of interventions outside of clinical research settings. Issues and approaches proposed as warranting further development and attention include development, flexibility, acceptability, and disseminability of psychosocial assessment and treatment methods. A research emphasis is promoted that balances experimental control with the need for treatment generalization and delivery outside of the research setting, in order to maximize the utility of clinical research.
