Design-based methods have recently been developed as a way to analyze randomized controlled trial (RCT) data for designs with a single treatment and control group. This article builds on this framework to develop design-based estimators for evaluations with multiple research groups. Results are provided for a wide range of designs used in…

Informant agreement is a common research issue in the context of children social emotional assessment. The present study analyzed parent--teacher agreement in ratings of behavior problems (BPs) using latent profile analysis (LPA). Analyses were performed for 1000 preschoolers rated, for the Preschool and Kindergarten Behavior Scales -- Second…

Events such as curriculum changes or practice effects can lead to item parameter drift (IPD) in computer adaptive testing (CAT). The current investigation introduced a point- and weight-adjusted D[superscript 2] method for IPD detection for use in a CAT environment when items are suspected of drifting across test administrations. Type I error and…

Attention allocation determines the information that is encoded into memory. Can participants learn to optimally allocate attention based on what types of information are most likely to change? The current study examined whether participants could incidentally learn that changes to either high spatial frequency (HSF) or low spatial frequency (LSF)…

The latest version of the connectionist dual process model of reading (CDP++.parser) was tested on a set of nonwords, many of which were orthographically strange (e.g., PSIZ). A grapheme-by-grapheme read-out strategy was used because the normal strategy produced many poor responses. The new strategy allowed the model to produce results similar to…

The aim of this study is to investigate the effect of intensive basketball competitions (10 official basketball games in 12 days intensive competition period) on blood parameters of basketball players. Blood samples were taken from the basketball players of the university team. The players were training regularly and they had no regular health…

Popular and accessible before television and the internet, picture books capture the context of the time they were created and influence the generations of children who consume them. Depictions of the natural world have changed across several generations of picture books as seen in illustrations of all 249 books of an influential collection, the…

Teaching profession is one of the hardest jobs of today. Teachers who raise the safeguards of our future, that is, our students should be aware of the principles, methods and techniques needed for teaching; should have taken the pedagogical formation training, should have enhanced communication skills and should closely follow science and…

The present study investigated the relationship between category extension and intension for 11 different semantic categories. It is often tacitly assumed that there is a (strong) extension-intension link. However, a recent study by Hampton and Passanisi (2016) examining the patterns of stable individual differences in concepts across participants…

Awe is a complex emotion characterized by feelings of vastness and a need for accommodation. The aim of this study was to investigate whether the experience of awe impacts on peculiar dimensions of creative potential in terms of creative thinking. Fifty-two university students were exposed both to an awe-inducing 3D-video and to a neutral one in a…

Self-set goals, selected by students for themselves, have known motivational benefits leading to increased autonomy and intrinsic motivation. In spite of the motivational benefits, students often fail to accomplish self-set goals because they lack the social motivator ascribed to assigned goals. The purpose of this research was to investigate…

The 0.70 and 0.80 reliability standards, proposed by Jum Nunnally, are widely employed across a spectrum of research domains. Nonetheless, due to their arbitrary nature, both standards fail to satisfy the needs of researchers. This paper presents a set of formulas that can be used to compute minimum reliability standards as a function of a…

Design-based methods have recently been developed as a way to analyze data from impact evaluations of interventions, programs, and policies (Freedman, 2008; Lin, 2013; Imbens and Rubin, 2015; Schochet, 2013, 2016; Yang and Tsiatis, 2001). The non-parametric estimators are derived using the building blocks of experimental designs with minimal…

To answer the call of introducing more Bayesian techniques to organizational research (e.g., Kruschke, Aguinis, & Joo, 2012; Zyphur & Oswald, 2013), we propose a Bayesian approach for meta-analysis with power prior in this article. The primary purpose of this method is to allow meta-analytic researchers to control the contribution of each…

The four paradigms are influential philosophical stances applied to advocate social research designs since they have been supported by eight different analytical lenses and had various functions for analysing the research nature as well as social phenomena based on two main analytical approaches, objective and subjective viewpoints. After…
