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

Declining food availability, corticosterone, and migratory response in a nomadic, irruptive migrant.
TL;DR: Results suggest that initial energetic state and corticosterone response may interact to determine an individual's behavioral and physiological response to declining food availability and ultimately the facultative migratory response.

Dyadic incongruence in chronic heart failure: Implications for patient and carer psychological health and self-care.
TL;DR: Findings indicate that dyadic incongruence in illness management might not affect high-functioning chronic heart failure heart failure patients or their carers.

Water Consumption during a School Day and Children's Short-Term Cognitive Performance: The CogniDROP Randomized Intervention Trial.
Alina Drozdowska,Michael Falkenstein,Gernot Jendrusch,Petra Platen,Thomas Luecke,Mathilde Kersting,Kathrin Jansen +6 more
TL;DR: The results suggest that a water-friendly environment supports school-aged children in adequate water intake resulting in better cognitive performance, especially short-term memory.

Are portrait artists superior face recognizers? Limited impact of adult experience on face recognition ability.
TL;DR: It is suggested that there is relatively little plasticity in face recognition in adulthood, at which point the authors' substantial everyday experience with faces may have pushed us to the limits of their capabilities.

Applied multiple regression/correlation analysis for the behavioral sciences
TL;DR: In this article, the Mathematical Basis for Multiple Regression/Correlation and Identification of the Inverse Matrix Elements is presented. But it does not address the problem of missing data.
