Research in psychology and education tend to use large-N group designs that necessitate reporting of mean measures analyzed mostly with null hypothesis statistical testing (NHST), but sometimes with Bayesian, or the estimation approaches in inferential statistics. These approaches all render the average person or student as the the putative…

An increased focus on transparency and replication in science has stimulated reform in research practices and dissemination. As a result, the research culture is changing: the use of preregistration is on the rise, access to data and materials is increasing, and large-scale replication studies are more common. In this article, I discuss two…

Evidence-based practices (EBP) in psychology and education are necessary for the development of best practices and required by law. However, EBP is a term that is often freely applied in these settings without considering the implications of the meaning of "evidence-based." Evidence-based practices are defined as the process of…

Having surveyed the history and methods of meta-regression in a previous paper, in this paper, we review which and how meta-regression methods are applied in recent research syntheses. To do so, we reviewed studies published in 2016 across four leading research synthesis journals: "Psychological Bulletin," the "Journal of Applied…

Power and inequality are central concepts in feminist theory and practice. Yet, with a few notable exceptions, there is relatively little empirical research on gender and power within feminist psychology. A search of PsycINFO for articles published in "Psychology of Women Quarterly" for the years 2000-2011 yielded only 14 empirical articles with…

The prevailing assumption by some that deep processing promotes stronger learning outcomes while surface processing promotes weaker learning outcomes has been called into question by the inconsistency and ambiguity of results in investigations of the relation between levels of processing and performance. The purpose of this literature review is to…

Video game playing has received increased academic interest over the last few decades, particularly with regard to the psychological understanding of addiction. Based on the many studies carried out by the authors, this paper summarises some of the methodological challenges which may arise when studying video game players, including obstacles…

This article proposes that psychological research published in APA journals focuses too narrowly on Americans, who comprise less than 5% of the world's population. The result is an understanding of psychology that is incomplete and does not adequately represent humanity. First, an analysis of articles published in six premier APA journals is…

Statistical reform in school psychology research is discussed in terms of research designs, measurement issues, statistical modeling and analysis procedures, interpretation and reporting of statistical results, and finally statistics education.

The origin of the present comment lies in a failed attempt to obtain, through e-mailed requests, data reported in 141 empirical articles recently published by the American Psychological Association (APA). Our original aim was to reanalyze these data sets to assess the robustness of the research findings to outliers. We never got that far. In June…

Unnecessary polarization between research traditions (basic vs. applied, experimental vs. correlational, and laboratory vs. field research) has resulted in extreme, nonproductive conflict between experimental rigor and policy relevance. The analogue model (described) grounds experimental studies in social problems without losing the unique…

In their article, "Disconfirmation of the Predictive Validity of the Self-Appraisal Questionnaire in a Sample of High-Risk Drug Offenders," criminologists Mitchell and MacKenzie (2006) purported to evaluate psychometric properties of the Self-Appraisal Questionnaire (SAQ), the first self-report risk/need measure estimating violent and nonviolent…

Some contemporary trends in social and clinical psychology suggest that individual differences in imaging abilities may become increasingly important. Outlines some of the conceptual and methodological problems that must be clarified if productive research is to be undertaken and reports results of three studies designed to isolate tests which…

A careful review of methodological principles provides a reasonable framework for beginning to sort out the apparently contradictory studies of the psychological consequences of natural disasters. (Author)

In psychological and special education research, group comparison experimental designs are more often used than single subject experimental designs. However, the application of group designs poses many difficulties, such as the collection of large numbers of homogeneous subjects for a particular experimental condition, the averaging of individual…
