Association of financial and health literacy with cognitive health in old age

We tested the hypothesis that higher financial and health literacy is associated with better cognitive health in 755 older persons who completed a literacy measure (M = 67.9, SD = 14.5) and then had annual clinical evaluations for a mean of 3.4 years. In proportional hazards models, higher literacy was associated with decreased risk of developing incident Alzheimer’s disease (n = 68) and results were similar for financial and health literacy subscales and after adjustment for potential confounders. In mixed-effects models, higher literacy was related to higher baseline level of cognition and reduced cognitive decline in multiple domains. Among the 602 persons without any cognitive impairment at baseline, higher literacy was associated with a reduced rate of cognitive decline and risk of developing incident mild cognitive impairment (n = 142). The results suggest that higher levels of financial and health literacy are associated with maintenance of cognitive health in old age.     

Early literacy and early numeracy: the value of including early literacy skills in the prediction of numeracy development

The purpose of this study was to examine whether early literacy skills uniquely predict early numeracy skills development. During the first year of the study, 69 3- to 5-year-old preschoolers were assessed on the Preschool Early Numeracy Skills (PENS) test and the Test of Preschool Early Literacy Skills (TOPEL). Participants were assessed again a year later on the PENS test and on the Applied Problems and Calculation subtests of the Woodcock–Johnson III Tests of Achievement. Three mixed effect regressions were conducted using Time 2 PENS, Applied Problems, and Calculation as the dependent variables. Print Knowledge and Vocabulary accounted for unique variance in the prediction of Time 2 numeracy scores. Phonological Awareness did not uniquely predict any of the mathematics domains. The findings of this study identify an important link between early literacy and early numeracy development.     

The Flynn effect in South Africa

This is a study of secular score gains in South Africa. The findings are based on representative samples from datasets utilized in norm studies of popular mainstream intelligence batteries such as the WAIS as well as widely used test batteries which were locally developed and normed in South Africa. Flynn effects were computed in three ways. First, studies where two different groups take the same test, with several years in between, using representative or comparable samples were used. Second, studies where the same group takes two different test batteries at a specific time were used. Third, the score differences between English- and Afrikaans-speaking Whites in South Africa in the 20th century were compared. The Flynn effect in White groups in South Africa is somewhat smaller than the Flynn effect in Western, industrialized countries (total N = 6534), and the Flynn effect in Indian groups is substantially smaller (total N = 682). Non-verbal IQ scores surpassed increases in verbal IQ scores. The findings from English- and Afrikaans-speaking Whites evidence a leveling out of differences in score gains over the 20th century (total N = 79,310). A meta-regression analysis showed no clear support for the moderators a) method used for computing the Flynn effect gain, b) type of test battery, c) time span, d) quality of the sample, and e) average age of sample.     

Poor Imitative Performance of Unlearned Gestures in Children with Probable Developmental Coordination Disorder

It has been hypothesized that deficits in imitation, linked to abnormal functioning of the mirror neuron system (MNS), may contribute to the motor impairments associated with developmental coordination disorder (DCD). The authors aimed to examine imitation of complex novel postures and sequences of gestures in children with and without probable DCD (pDCD), using the postural praxis and sequencing praxis subtests of the Sensory Integration and Praxis Tests (Ayres, 1989 Ayres, A. J. (1989). Sensory Integration and Praxis Tests: SIPT manual. Los Angeles, CA: Western Psychological Services. [Google Scholar]). Participants were 29 boys with pDCD between 6.08 and 13.33 years old, and 29 group age-matched typically developing boys between 6.08 and 13.83 years old. Responses of children with pDCD on both imitation tasks were less accurate than controls, with group differences more apparent with increasing task complexity. Furthermore, as a group, children with pDCD were slower and had a higher number of non–mirror-imitated responses. There was considerable variability within the pDCD group, with some children displaying imitation scores within the normative range. Given the importance of imitation and visual learning for motor development, the difficulties in imitation displayed by some children with pDCD have the potential to impact on movement acquisition. Interventions to target imitation may be beneficial for these children. The results show that children with pDCD had difficulty imitating complex novel postures, children with pDCD had difficulty imitating gesture sequences, children with pDCD had slower responses than controls, group differences in imitation performance increased with task complexity, and not all children with pDCD displayed imitation deficits.     

Trying on and Trying Out: Participatory Action Research as a Tool for Literacy and Identity Work in Middle Grades Classrooms

This article explores the role of collaborative, ethnographic, participatory action research (PAR) with eighth grade students as a set of possible literacy practices for involving students with issues connected to their lives, resources, language(s), and communities. Findings are based on a year of fieldwork conducted as part of shared inquiry into one public school community’s experiences with gentrification and meeting the complex needs of diverse learners. Findings bring to life the ways in which PAR facilitates the redefining of reading, writing, and research; the reconsideration of languages; the rethinking of literacy practices; and the repositioning of participants within and beyond given research endeavors.     

儿童家庭读写活动、早期读写水平与小学一年级语文课成绩的关系

从读写萌发的观点出发,探讨6至7岁儿童的家庭读写活动、早期读写水平与其在校语文成绩的关系。研究结果显示:在控制儿童的非言语智力和父母的教育水平等变量后,(1)只有儿童的非正式家庭读写活动能够显著预测其口头词汇;(2)只有儿童的正式家庭读写活动能够显著预测其识字量;(3)只有儿童入学时的识字量能够显著预测他们一年级时的语文成绩和平时语文课表现;(4)儿童的口头词汇和家庭读写活动均无法预测其在校的语文课成绩。     

Development of Phonological Awareness

Abstract— Phonological awareness is critical for learning to read in alphabetic languages like English. This report summarizes normal development of phonological awareness as it has been revealed through recent multidisciplinary and cross-cultural research. We argue that a consensus on the definition of phonological awareness has emerged, that research has identified a general sequence of phonological awareness development that is universal across languages, and that certain characteristics of spoken and written languages influence the rate of normal development and levels of phonological awareness that are normally achieved.     

Cross-country gender DIF in PISA science literacy items

This study investigated gender based differential item functioning (DIF) in science literacy items included in the Program for International Student Assessment (PISA) 2012. Prior research has suggested presence of such DIF in large scale surveys. Our study extends the empirical literature by examining gender based DIF differences at the country level in order to gain a better overall picture of how cultural and national differences affect occurrence of uniform and nonuniform DIF. Our statistical results indicate existence of widespread gender based DIF in PISA with estimates of percentage of potentially biased items ranging between 2 and 44% (M = 16, SD = 9.9). Our reliance on nationally representative country samples allow these findings to have wide applicability.
