This best-selling text explains the basic principles of psychological assessment and measurement and guides students and practitioners in the appropriate selection, interpretation, and communication of test results. Danica Hays introduces more than 150 assessment instruments used to evaluate mental health, intelligence, career development,…

To enable optimal decision-making based on the best evidence available, open syntheses are called for. To make data accessible and comprehensible even for decision-makers without proficient knowledge in meta-analysis, a graphical user interface (GUI) provides flexible data visualizations including interpretation aids. Moreover, due to a growing…

Self-determination theory, like other psychological theories that study eudaimonia, focuses on general processes of growth and self-realization. An aspect that tends to be sidelined in the relevant literature is virtue. We propose that special focus needs to be placed on moral virtue and its development. We review different types of moral…

A latent variable modeling-based procedure is discussed that permits to readily point and interval estimate the design effect index in multilevel settings using widely circulated software. The method provides useful information about the relationship of important parameter standard errors when accounting for clustering effects relative to…

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…

Introduction: Poverty is a central concept in many fields of psychology, yet poorly designed activities regarding wealth inequality may backfire or cause students to become defensive. Statement of the Problem: Many students hold misperceptions about class mobility and lack an understanding of how systemic barriers perpetuate poverty across the…

Assessments of natural language can provide vast information about individuals' thoughts and cognitive process, but they often rely on time-intensive human scoring, deterring researchers from collecting these sources of data. Natural language processing (NLP) gives researchers the opportunity to implement automated textual analyses across a…

In this essay we begin with a discussion of what we call the "great gap" between our research and its influence on society. We point out that although there is ample evidence speaking to these areas, a lack of societal change suggests that evidence has largely gone unnoticed, ignored, or not well promoted or disseminated. Throughout this…

The world is facing complex global societal challenges including accelerating climate change, a pandemic, rising social inequalities also in well-functioning welfare states, cultural and linguistic diversity, and a renewed call for racial justice. Developmental psychology can make strong contributions to address these and other global challenges…

Building bridges between two of the most influential research fields in educational psychology, self-regulation and cognitive load theory, is highly relevant but also challenging. The collection of papers in this special issue reflects this interplay by reviewing the still scarce base of empirical data in an impressively elaborated and profound…

We discuss possible uses of multilevel mixed methods (M[superscript 3]) research in educational psychology. To begin, we describe M[superscript 3] research and how such research can enable researchers to investigate potential variation at the group level and at the subgroup/individual level. We discuss why M[superscript 3] research designs are…

Although there is increasing recognition of the value of mixed-methods research, many publication spaces remain methodologically siloed, primarily publishing either qualitative or quantitative research studies. This methodological siloing presents a risk to coherence in the psychological sciences if qualitative and quantitative research traditions…

Digital technologies play an important role in our daily lives. Smartphones and tablet computers are very common worldwide and are available for everybody from a very early age. This trend offers the opportunity to track digital usage data for psychological and educational research purposes. The current paper introduces two research projects, the…

Introduction: Cognitive psychology courses are rich in content that can be useful to broad audiences. Much of the foundational research presented in course texts is conducted in highly constrained laboratory settings, making the concepts difficult to apply or use in the real world. Statement of the Problem: Students in cognitive psychology classes…

Introduction: Undergraduate research experiences prepare students for graduate training or employment. Statement of problem: At many teaching-intensive universities, there is a greater demand for research experiences than there are independent study opportunities. Students from typically underrepresented backgrounds may also be unaware of a…
