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…

Data collection can be the most time- and cost-intensive part of developmental research. This article describes some long-proposed but little-used research designs that have the potential to maximize data quality (reliability and validity) while minimizing research cost. In "planned missing data designs", missing data are used…

In this systematic review, we evaluated the evidence base of self-regulated strategy development (SRSD; Harris & Graham, 1992) for writing with students with and at risk for emotional or behavioral disorders (EBD). First, we evaluated the quality of studies identified (n 5 13) by applying the quality indicators for single case (Horner et al.,…

Acquiring research skills is considered to be a highly challenging aspect of developing expertise in the social sciences. Because instruction and mentoring in these skills are typically grounded in the self-report of researchers, difficulties in learning the material may be due to the content and accuracy of these explanations. Using a…

Individuals with Down syndrome are predisposed to show a specific behavioural phenotype, or a pattern of strengths and challenges in functioning across different domains of development. It is argued that a developmental approach to researching the Down syndrome behavioural phenotype, including an examination of the dynamic process of the unfolding…

The purpose of this study was to determine whether or not the elementary school principal has an impact on the outcomes of schooling manifested by students and, if so, to determine the nature of the role of the principal in influencing cognitive and affective outcomes manifested by students. The three sets of principal-related variables used were…

The present study investigated egocentricity in children and youth. Exner's Self-Focus Sentence Completion (SFSC) was used to measure egocentricity. (Author/RK)

The purpose of the present investigation was to examine the relationship between the stages of cognitive development proposed by L.S. Vygotsky and by J. Piaget. (Author)

The major purpose of the study is an attempt to clarify some of the issues involved in the theoretical controversy that exists between Piagetian and American-Soviet positions. (Author)

Familiarizes educators and researchers with a method to develop curriculum according to the individual cognitive styles of individual students. (Author)

This report concerns the field procedures and data analysis being used in the New York City Infant Day Care Study, a large-scale longitudinal study examining publicly-funded, community-controlled group and family day care programs in New York and comparing the effects of these programs and of home rearing on children and their families. Children's…

Measuring cognitive achievement gains in project evaluation is dealt with. This guide provides those concerned with project evaluation with the basic tools for conducting technically sound, interpretable evaluation studies. Exotic designs are avoided and five basic models which appear feasible to implement in real-world settings are focused on.…

This research addressed the question of whether variations in instructional strategies which incorporate ideas from social learning theory lead to significant growth among bright underachievers. (Author/RK)

Using Quay's typology, three equal groups (n=12) of adolescent psychopathic, neurotic, and subcultural delinquent males and a matched nondelinquent control group were individually administered Kohlberg's structured moral dilemmas, two Piagetian tasks of cognitive development (pendulum and balance), and an adaptation of Flavell's role-taking task.…

Considers the controversy between Bruner "et al." (1966) and Piaget (Inhelder & Piaget, 1964) followed up by Sinclair-de-Zwart (1967) concerning the role of language in the cognitive development of children between the ages of 5 and 7. (Author/RK)
