In this paper, a method for combining results across independent-groups and repeated measures designs is described, and the conditions under which such an analysis is appropriate are discussed, and a meta-analysis procedure using design-specific estimates of sampling variance is described.Abstract:
When a meta-analysis on results from experimental studies is conducted, differences in the study design must be taken into consideration. A method for combining results across independent-groups and repeated measures designs is described, and the conditions under which such an analysis is appropriate are discussed. Combining results across designs requires that (a) all effect sizes be transformed into a common metric, (b) effect sizes from each design estimate the same treatment effect, and (c) meta-analysis procedures use design-specific estimates of sampling variance to reflect the precision of the effect size estimates.read more

A Meta-Analysis on Gender Differences in Mental Rotation Ability Measured by the Purdue Spatial Visualization Tests: Visualization of Rotations (PSVT:R)
Yukiko Maeda,So Yoon Yoon +1 more
TL;DR: In this paper, a meta-analysis was conducted to estimate the magnitude of gender difference in three-dimensional (3D) mental rotation ability and investigate how factors related to test administration conditions play a role in varying gender difference effect sizes and threatening validity.

The effects of acute stress on episodic memory: A meta-analysis and integrative review.
TL;DR: The analyses indicate that stress disrupts some episodic memory processes while enhancing others, and that the effects of stress are modulated by a number of critical factors.

Leadership training design, delivery, and implementation: A meta-analysis.
TL;DR: Results suggest that leadership training is substantially more effective than previously thought, leading to improvements in reactions, learning, transfer, and results, and the strength of these effects differs based on various design, delivery, and implementation characteristics.

Attentional bias to pain-related information: A meta-analysis
TL;DR: This meta‐analysis investigated whether attentional bias, that is, the preferential allocation of attention to information that is related to pain, is a ubiquitous phenomenon, and indicated that individuals who experience chronic pain display an attentional biased towards pain‐related words or pictures.

The neurocognitive consequences of sleep restriction: A meta-analytic review.
TL;DR: The current meta‐analysis is the first comprehensive review to provide evidence that short‐term sleep restriction significantly impairs waking neurocognitive functioning.

Statistical Methods for Meta-Analysis

TL;DR: In this article, the authors present a model for estimating the effect size from a series of experiments using a fixed effect model and a general linear model, and combine these two models to estimate the effect magnitude.
