Amid recent progress in cognitive development research, high-quality data resources are accumulating, and data sharing and secondary data analysis are becoming increasingly valuable tools. Integrative data analysis (IDA) is an exciting analytical framework that can enhance secondary data analysis in powerful ways. IDA pools item-level data across…

Geometry is one of the highest achievements of our species, but its foundations are obscure. Consistent with longstanding suggestions that geometrical knowledge is rooted in processes guiding navigation, the present study examines potential sources of geometrical knowledge in the navigation processes by which young children establish their sense…

A brief review is provided of recent research on the impact of early visual language exposure on a variety of developmental outcomes, including literacy, cognition, and social adjustment. This body of work points to the great importance of giving young deaf children early exposure to a visual language as a critical precursor to the acquisition of…

University and high school students not pursuing a science, technology, engineering, and/or mathematics (STEM) course of study demonstrate less developed scientific reasoning than their STEM-based peers. Previous studies show that the majority of non-STEM students can be classified as either concrete operational or transitional reasoners in…

The North Carolina Governor's School offers a six-week residential summer program for four hundred academically talented rising juniors. This article measures the school's impact on these students in four fundamental areas: cognitive maturity, moral reasoning, personal learning style, and projections for the future. The results showed that…

The aim of the present study was to evaluate whether the application of Dutch versus US test procedures and norms of the Bayley Scales of Infant Development-2nd edition (BSID-II) leads to different developmental outcomes. The BSID-II was administered to 376 preterm infants (191 males, 185 females; mean gestational age 30wks [SD 2.7], mean…

We hypothesized that women with Turner syndrome (45,X) with a single X-chromosome inherited from their mother may show mentalizing deficits compared to women of normal karyotype with two X-chromosomes (46,X). Simple geometrical animation events (two triangles moving with apparent intention in relation to each other) which usually elicit…

Questionnaire results from l04 psychologists serving the blind and partially sighted indicated disagreement on the tests used and on the evaluation of these tests. Tests of all kinds from 45 publishers were rated, and appropriate ages and populations (blind, partially-sighted) were suggested. (CP)

Dynamic assessment (DA), as a pro-learning form of assessment, has been discussed in the educational literature for three decades or more. As a concept it has yet to be picked up in any significant way by the more established second language testing/assessment literature published in the English language. There is, however, every reason to believe…

Summarizes school readiness and retention research issues, including youngest first graders' performance, entrance age policies, voluntary decisions to wait an extra year, assessment of children's readiness, and the negative effects of kindergarten and first-grade retention. Concludes that age disadvantages are seldom serious and usually disappear…

The counterintuitive developmental trend in the Deese-Roediger-McDermott (DRM) illusion (that false-memory responses increase with age) was investigated in learning-disabled and nondisabled children from the 6- to 14-year-old age range. Fuzzy-trace theory predicts that because there are qualitative differences in how younger versus older children…

This article is a commentary for the special issue on the Early Development Instrument (EDI), a community tool to assess children's school readiness and developmental outcomes at a group level. The EDI is administered by kindergarten teachers, who assess their kindergarten students on 5 developmental domains: physical health and well-being, social…

Despite the increasing use of the microgenetic methodology to examine change, the techniques employed to analyse microgenetic data remain fairly unsophisticated. This paper reviews the existing ways of analysing such data and describes their limitations. We use two recent studies to illustrate how modelling can avoid these problems and reveal…

Two alternative hypotheses can be used to explain how young children acquire the cardinal meaning of small-number words. The first stresses the role of counting and predicts better performance when the items are presented in succession. The second considers the role of subitizing and predicts better performance when the items are presented…

The Stanford-Binet Intelligence Scale-Revised and the Kaufman Assessment Battery for Children (K-ABC) were compared using a sample of 26 developmentally disabled children, aged 32 to 73 months. The focus of the study was to determine the feasibility of the K-ABC both for assessment and for planning more effective remediation programs for this…
