Effect size estimates: Current use, calculations, and interpretation.
TLDR
A straightforward guide to understanding, selecting, calculating, and interpreting effect sizes for many types of data and to methods for calculating effect size confidence intervals and power analysis is provided.Abstract:
The Publication Manual of the American Psychological Association (American Psychological Association, 2001, American Psychological Association, 2010) calls for the reporting of effect sizes and their confidence intervals. Estimates of effect size are useful for determining the practical or theoretical importance of an effect, the relative contributions of factors, and the power of an analysis. We surveyed articles published in 2009 and 2010 in the Journal of Experimental Psychology: General, noting the statistical analyses reported and the associated reporting of effect size estimates. Effect sizes were reported for fewer than half of the analyses; no article reported a confidence interval for an effect size. The most often reported analysis was analysis of variance, and almost half of these reports were not accompanied by effect sizes. Partial η2 was the most commonly reported effect size estimate for analysis of variance. For t tests, 2/3 of the articles did not report an associated effect size estimate; Cohen's d was the most often reported. We provide a straightforward guide to understanding, selecting, calculating, and interpreting effect sizes for many types of data and to methods for calculating effect size confidence intervals and power analysis.read more

Executive Functioning in Criminal Behavior: Differentiating between Types of Crime and Exploring the Relation between Shifting, Inhibition, and Anger
TL;DR: In this article, a general sample of offenders (N = 42), further divided into three subtypes of crimes (violent, property, and drug trafficking), was tested using a battery of executive functioning measures and compared with a group of non-offenders.

Context matters: The structure of task goals affects accuracy in multiple-target visual search
TL;DR: Results indicate that participants searching within the fixed objective framework produced more multiple-target search errors; thus, adopting a fixed duration framework could improve accuracy for career searchers.

Power-Ups in Digital Games: The Rewarding Effect of Phantom Game Elements on Player Experience
Alena Denisova,Eliott Cook +1 more
TL;DR: An experimental study that compares the experiences of players depending on their exposure to power-ups in a recreational video game shows that players who collected power-up felt significantly more immersed in the game, experienced more autonomy, but did not feel more competent or challenged than those who played the game without these collectables.
