In 1995, Nelson explored the relation between early memory development and corresponding changes in brain development, and conceptualized this knowledge in a coherent theoretical framework (Nelson, 1995). In their review, Jabe's and Nelson provide an update of Nelson's 1995 cognitive neuroscience model of human memory development. In this article,…

Molenaar's (2015) article concerns Developmental Systems Theory (DST) in relation to behavior genetics and he presents implications of DST for empirical research, especially the need for subject-specific studies. In this commentary, the article is discussed from a broader developmental science perspective, particularly regarded through the lens of…

This discussion article addresses issues related to expansion of the Wechsler model from four to five factors; multiple broad CHC abilities measured by the Arithmetic subtest; advantages and disadvantages of including complex tasks requiring integration of multiple broad abilities when measuring intelligence; limitations of factor analysis, which…

This article presents the author's response to Hisham Ghassib's paper entitled "Where does creativity fit into a productivist industrial model of knowledge production?" In his paper, Ghassib (2010) explores the epistemological ramifications of science becoming a major industry, which is generally called the knowledge industry. In particular, he…

In response to Howe (2009), the author argues that educational research needs multiple thoughtful perspectives. The author's standpoint is that of a mixed methods research methodologist. Mixed methods research provides an antidualistic and syncretic philosophy and set of approaches or possibilities for merging insights from diverse perspectives;…

The usefulness of positivist traditions in education research has been debated for some time, and there continue to be various epistemological and methodological camps regarding the question of what constitutes "good" or "real" research. The importance of educating all children necessitates that we think about what are the most effective and most…

The debate between Simulation-Theory (ST) and Theory-Theory (TT) provides the dominant theoretical framework for research on "theory of mind" (ToM). Behavioural research has failed to provide clear methods for discriminating between these theories, but a number of recent studies have claimed that neuroimaging methods do allow key predictions of ST…

It has been suggested that the enterprise of developing mechanistic theories of the human cognitive architecture is flawed because the theories produced are not directly falsifiable. Newell attempted to sidestep this criticism by arguing for a Lakatosian model of scientific progress in which cognitive architectures should be understood as theories…

Many realms of social inquiry, particularly public administration, are in the midst of an era of unprecedented epistemological introspection, driven primarily by frustration with the prevailing positivism of applied research. Rebuilding the systems paradigm requires recognition of its alternative view of scientific enterprise, its ability to…

A method for assessing scientific performance based on relationships displayed numerically in published documents is proposed and illustrated using published documents in pediatric oncology for the period 1979-1982. Contributions of a major clinical investigations group, the Childrens Cancer Study Group, are analyzed. Twenty-nine references are…

Successful interdisciplinary research performance, it is suggested, depends on such structural and process factors as leadership, team characteristics, study bounding, iteration, communication patterns, and epistemological factors. Appropriate frameworks for socially organizing the development of knowledge such as common group learning, modeling,…

This article presents a queuing model simulation of scientific productivity utilizing critical path analysis. Creativity is found to have a large positive effect, a negative effect, or no effect on productivity, depending on the stage of the problem-solving process to which it is applied and the nature of the bottlenecks inherent to the specific…

Chwalisz's (2003) [this issue]) call to adopt the evidence-based practice model provides an opportunity for counseling psychologists to reexamine both their commitment to the scientist-practitioner model and their unique professional identity. In this reaction, the author offers her critique of several assumptions underlying the evidence-based…

Focuses on the analysis of Thomas S. Kuhn's book, "The Structure of Scientific Revolutions." Science history is reviewed as it is viewed through the idea of a paradigm. The sequence in science or life cycle of a paradigm is explained. (SA)

Contends that composition studies risks a detrimental borrowing of prestige from science, a borrowing that is not only potentially misleading but also too limiting if it draws attention away from the broad spectrum of considerations inherent in composition studies. (RAE)
