Research on spatial navigation is essential to understanding how mobile species adapt to their environments. Such research increasingly uses virtual environments (VEs) because, although VE has drawbacks, it allows for standardization of procedures, precision in measuring behaviors, ease in introducing variation, and cross-investigator…

Background: Research into Rett syndrome has included various medical interventions. Non-medical interventions are relatively under-researched. Recent technological communication intervention advances have contributed to the evidence base in Rett syndrome. Method: The Embase, PsycINFO and MEDLINE were systematically searched for peer-reviewed…

The current article discusses the importance of increasing racial-ethnic and socioeconomic diversity in cognitive developmental research. It begins with discussion of the implications of the underrepresentation of ethnic minority children in cognitive developmental research. It goes on to suggest reasons underlying these omissions, such as the…

This evidence review synthesises the best available international evidence regarding approaches to behaviour in schools to: (1) Produce an overarching model or framework explaining why school pupils may misbehave (Review 1); (2) Review the effectiveness of classroom-based approaches to behaviour trialled in robust research studies (Review 2); and…

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…

Despite the potential impact nutrition may have on learning, there have been surprisingly few papers published directed towards the educational research community. In contrast, omega-3 supplementation studies are being frequently cited in the media, leading to parents asking for advice and guidance. The purpose of this article is to review the…

The outcomes of collaboration provide an incomplete and potentially misleading picture of cognitive change, one that is clarified by examining the collaborative processes themselves. Results from a study illustrate the dangers of focusing solely on the consequences of collaboration and emphasize why the analysis of collaborative processes is…

Investigated the cognitive development of children with emotional and behavioral difficulties (EBDs). Found that children with EBDs showed a similar order of acquisition of conservation as normal children, and the thinking of children with EBDs was characterized by a high degree of uncertainty. (BC)

Lev Vygotsky maintained that historical and cultural aspects of development started from the point at which humans could first be distinguished from apes. It is critical to consider the dialectical relationship between the individual and the cultural environment in which the child actively masters cultural behavior. Interaction with others…

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…

Examines several possible difficulties in interpreting the results of studies which employ Piagetian tasks, especially conservation tasks, with older individuals. Notes that Piaget's clinical method allows more flexibility in the assessment of competence than do more quantifiable techniques. Examines the possibility of task misinterpretation by…

Presents two reasons for abandoning the false belief task as a methodology for theory of mind: (1) passing the false belief task requires ability other than theory of mind; and (2) theory of mind need not entail the ability to reason about false beliefs. Concludes with an alternative conception of the role of the false belief task. (Author)

Comments on Damon and Killen's study, pointing out that the methodological difficulties in examining spontaneous moral discussions have led to the appropriation of a dyadic social-cognitive conflict paradigm that focuses on dialogic interaction. (Author/RH)

Proposes an interference explanation of data from dual-task studies of memory development. Dual-task data support the resources hypothesis that memory processes tax a common pool of cognitive energy, which has been variously called attentional, mental effort, and working-memory capacities. Suggests that dual-task deficits are instances of output…

From a statistical methodological standpoint, criticizes research by Hicks, Langham, and Takenaka, which found significant differences in behavioral and intelligence measures between children with different time periods of participation in the National Special Supplemental Food Program for Women, Infants, and Children (WIC) program.
