Spanish developmental dyslexia: Prevalence, cognitive profile, and home literacy experiences

This study was designed to examine the prevalence, cognitive profile, and home literacy experiences in subtypes of Spanish developmental dyslexia. The subtyping procedure used comparison with chronological-age-matched and reading-level controls on reaction times and accuracy responses to high-frequency words and pseudowords. Using regression-based procedures, 8 phonological dyslexics and 16 surface dyslexics were identified from a sample of 35 dyslexic fourth graders by comparing them with chronological-age-matched controls on reaction times to high-frequency word and pseudoword reading. However, when the dyslexic subtypes were defined by reference to reading-level controls, 12 phonological dyslexics were defined but only 5 surface dyslexics were identified. Both dyslexic subtypes showed a deficit in phonological awareness, but children with surface dyslexia also showed a deficit in orthographical processing assessed by a homophone comprehension task. This deficit was associated with poor home literacy experiences, with the group of parents with children matched in reading age, in comparison with the group of parents with children with surface dyslexia, reporting more literacy home experiences.     

A cross-syndrome study of the development of holistic face recognition in children with autism, Down syndrome, and Williams syndrome

We report a cross-syndrome comparison of the development of holistic processing in face recognition in school-aged children with developmental disorders: autism, Down syndrome, and Williams syndrome. The autism group was split into two groups: one with high-functioning children and one with low-functioning children. The latter group has rarely been studied in this context. The four disorder groups were compared with typically developing children. Cross-sectional trajectory analyses were used to compare development in a modified version of Tanaka and Farah’s part–whole task. Trajectories were constructed linking part–whole performance either to chronological age or to several measures of mental age (receptive vocabulary, visuospatial construction, and the Benton Facial Recognition Test). In addition to variable delays in onset and rate of development, we found an atypical profile in all disorder groups. These profiles were atypical in different ways, indicating multiple pathways to, and variable outcomes in, the development of face recognition. We discuss the implications for theories of face recognition in both atypical and typical development, including the idea that part–whole and rotation manipulations may tap different aspects of holistic and/or configural processing.     

Development of perceptual expertise in emotion recognition

How do children’s early social experiences influence their perception of emotion-specific information communicated by the face? To examine this question, we tested a group of abused children who had been exposed to extremely high levels of parental anger expression and physical threat. Children were presented with arrays of stimuli that depicted the unfolding of facial expressions, from neutrality to peak emotions. The abused children accurately recognized anger early in the formation of the facial expression, when few physiological cues were available. The speed of children’s recognition was associated with the degree of anger/hostility reported by the child’s parent. These data highlight the ways in which perceptual learning can shape the timing of emotion perception.     

Toward an integrative and collaborative approach to Asian American and Pacific Islander youth violence research, practice, and policy

Research into the prevalence of violence and delinquency among Asian American and Pacific Islander (AAPI) youth has proliferated in the last several years, as a result of federal funding. Consequently, this article reviews the literature on AAPI youth violence and delinquency published from 2001 to 2008. The findings demonstrate the frequency of AAPI youth violence and delinquency, provide a sense of the involvement of these youth in the juvenile justice system, reveal ethnic group differences in violence and delinquency, and explore the effects of immigration and acculturation on these phenomena. This article ends with a discussion on AAPI youth violence and delinquency prevention programs, with suggestions for future directions that incorporate a developmental and life-course approach in research and collaboration among researchers, practitioners, and policymakers.     

Who is most likely to seek and give support in the face of agentic and communal threat? The roles of extraversion and agreeableness

Agentic threat tends to elicit support seeking and hinder support provision. Communal threat tends to elicit support seeking and provision. We examined whether the associations between threats and support are moderated by Extraversion and Agreeableness. Three hundred fifty undergraduate students completed questionnaires twice daily across one week, reporting the worst stressor of the half-day, appraisals of agentic and communal threats, and efforts to seek and provide support. In response to agentic threat, those higher in Extraversion increased their support seeking and decreased their support provision to a greater extent than those lower in Extraversion. In response to communal threat, those higher in Agreeableness increased their support seeking and provision to a greater extent than those lower in Agreeableness.     

Adapting and validating a developmental assessment for chinese infants and toddlers: The ages & stages questionnaires: Inventory

The Chinese government has announced the 2013 Guidelines for developing a national system for early detection of disability among children under 6 years of age. However, given limited resources, challenges exist with developmental measures required in the 2013 Guidelines. In order to meet the needs for a more accurate and cost-efficient measure for developmental assessment, the Ages & Stages Questionnaires: Inventory (ASQ:I) was translated into Simplified Chinese, and validated on a regional sample of 812 Chinese children ages from 1 to 25 months. Results indicated that the Chinese ASQ:I domain scores increased across children’s age. When dividing the sample into seven age intervals, Cronbach’s alpha in each interval ranged from 0.59 to 0.96 across five domains. When using the whole sample for analyses, item expected a posteriori/plausible value (EAP/PV) reliability was above 0.99 in all domains, test-retest reliability using intra-class correlation analyses ranged from 0.95 to 0.99, and the agreement with the concurrent measure ranged from 0.29 to 0.89. Domain scores on the ASQ:I correctly predicted 92–99% of participating children’s disability status. Findings suggested that the Chinese ASQ:I has adequate psychometric properties and thus provides a promising alternative measure for screening and progress monitoring in young children in China. Implications for future research and implementation are discussed.     

Models provide specificity: Testing a proposed mechanism of visual working memory capacity development

Numerous studies have established that visual working memory has a limited capacity that increases during childhood. However, debate continues over the source of capacity limits and its developmental increase. Simmering (2008) adapted a computational model of spatial cognitive development, the Dynamic Field Theory, to explain not only the source of capacity limitations but also the developmental mechanism. Capacity is limited by the balance between excitation and inhibition that maintains multiple neural representations simultaneously in the model. Development occurs according to the Spatial Precision Hypothesis, which proposes that excitatory and inhibitory connections strengthen throughout early childhood. These changes in connectivity result in increasing precision and stability of neural representations over development. Here we test this developmental mechanism by probing children's memory in a single-item change detection task. Results confirmed the model's predictions, providing further support for this account of visual working memory capacity development.     

Progress in the development of a multidimensional measure of fear of failure: The performance failure appraisal inventory (pfai)

Abstract

Measuring fear of failure (FF) is a tremendous challenge for researchers and practitioners because (a) existing measures have demonstrated limited support for the validity of their score interpretations, and (b) existing measures are unidimensional while accumulating evidence suggests that FF is multidimensional. The Performance Failure Appraisal Inventory (PFAI) was developed to measures a set of empirically-derived congnitive-motivational-relational appraisals associated with FF. Results indicated that PFAI scores represented fears of (a) experiencing shame and embarrassment, (b) devaluing one's self-estimate, (c) losing social influence, (d) having an uncertain future, and (e) upsetting important others. Correlations with external measures of achievement goal orientations, trait anxiety, and social desirability were consistent with theoretical predictions. PFAI scores correctly classified 76.5% of participants' perceptions of underachievement.     

The appraisal process: Exploring the role of meaning,importance, control and coping in work stress

Recent reviews on occupational stress research suggests that if progress is to be made towards a better understanding of stress at work then researchers need to consider alternative methodologies and establish new frameworks. This paper takes up that challenge and using both quantitative and qualitative techniques attempts to explore the appraisal process individuals go through in determining stressful experiences. The meanings individuals give to events, their importance and individual levels of control all provide fruitful avenues for further research. Such variables provide new approaches to research and offer a potential for explanation far greater than the more traditional interactional models.
