Abstract Although cross-linguistic influence at the level of morphosyntax is one of the most intensively studied topics in child bilingualism, the circumstances under which it occurs remain unclear. In this meta-analysis, we measured the effect size of cross-linguistic influence and systematically assessed its predictors in 750 simultaneous and early sequential bilingual children in 17 unique language combinations across 26 experimental studies. We found a significant small to moderate average effect size of cross-linguistic influence, indicating that cross-linguistic influence is part and parcel of bilingual development. Language dominance, operationalized as societal language, was a significant predictor of cross-linguistic influence, whereas surface overlap, language domain and age were not. Perhaps an even more important finding was that definitions and operationalisations of cross-linguistic influence and its predictors varied considerably between studies. This could explain the absence of a comprehensive theory in the field. To solve this issue, we argue for a more uniform method of studying cross-linguistic influence.

Assisted Instruction

This article concerns the effects of learner control in computer-assisted instruction (CAI). After reviewing previous reviews of research on the topic, twenty-four studies of learner control were subjected to meta-analysis. The results of both the review and meta-analysis are equivocal. Several reviews indicate that learner control works less well with younger, less able students. Other reviews indicate that, given optimal conditions, learner control can work with any students. The meta-analysis, however, yielded an average effect size that was small and negative suggesting that the average student would be slightly better off without it. Although learner control has theoretical appeal, its effects on learning seem neither powerful nor consistent.

Recently, Picho-Kiroga (2021) published a meta-analysis on the effect of stereotype threat on females. Their conclusion was that the average effect size for stereotype threat studies was d = .28, but that effects are overstated because the majority of studies on stereotype threat in females include methodological characteristics that inflate the apparent effect size. In this response, I show that Picho-Kiroga et al. (2021) committed fundamental errors in their meta-analysis that undermine confidence in the article and warrant major corrections. But even if the data were not flawed, the conclusion that Picho-Kiroga et al. (2021) should have reached is that their results are most consistent with a population effect size of zero. There is no compelling evidence that stereotype threat is a real phenomenon in females.

The equivocal and debated findings from a 2007 meta–analysis, which viewed perfectionism as a unidimensional construct, suggested that perfectionism was unrelated to procrastination. The present meta–analysis aimed to provide a conceptual update and reanalysis of the procrastination–perfectionism association guided by both a multidimensional view of perfectionism and self–regulation theory. The random–effects meta–analyses revealed a small to medium positive average effect size ( r = .23; k = 43, N = 10 000; 95% confidence interval (95% CI) [0.19, 0.27]) for trait procrastination and perfectionistic concerns and a small to medium negative average effect size ( r = −.22; k = 38, N = 9544; 95% CI [−0.26, −0.18]) for procrastination and perfectionistic strivings. The average correlations remained significant after statistically accounting for the joint variance between the two perfectionism dimensions via semi–partial correlations. For perfectionistic concerns, but not perfectionistic strivings, the effects depended on the perfectionism measure used. All effects did not vary by the trait procrastination measure used or the respondent's sex. Our findings confirm that from a multidimensional perspective, trait procrastination is both positively and negatively associated with higher–order perfectionism dimensions and further highlights the value of a self–regulation perspective for understanding the cognitive, affective and behavioural dynamics that characterise these traits.

Outcome reporting bias (ORB) refers to the biasing effect caused by researchers selectively reporting outcomes based on their statistical significance. ORB leads to inflated average effect size estimates in a meta-analysis if only the outcome with the largest effect size is reported due to ORB. We propose a new method (CORB) to correct for ORB that includes an estimate of the variability of the outcomes' effect size as a moderator in a meta-regression model. An estimate of the variability of the outcomes' effect size can be computed by assuming a correlation among the outcomes. Results of a Monte-Carlo simulation study showed that effect size in meta-analyses may be severely overestimated without any correction for ORB. The CORB method accurately estimates effect size when overestimation caused by ORB is the largest. Applying the new method to a meta-analysis on the effect of playing violent video games on aggressive cognition showed that the average effect size estimate decreased when correcting for ORB. We recommend to routinely apply methods to correct for ORB in any meta-analysis. We provide annotated R code and functions to facilitate researchers to apply the CORB method.

This study aims to determine the effect of physics teaching materials on student learning outcomes. The type of research used is a meta-analysis that analyzes 25 pre-existing national articles starting from 2013-2019. The data analysis technique used is to calculate the effect size for each article. Based on the results of the study, it was found that physics teaching materials had an effect on student learning outcomes. So that it is known that first, the influence of physics teaching materials on student learning outcomes from 25 articles obtained an average effect size of 1.1308 with a very high category. The effect of the two teaching materials based on education level with the highest effect size is at the junior high school level, namely 1,395 with a very high category. The third is based on the highest effect size class level in class VIII, namely 1,395 with a very high category. Fourth, based on the type of teaching materials with the highest effect size, namely 1,418 with a very high category on teaching materials. The fifth effect magnitude based on the highest learning material is found in the material for parabolic motion, circular motion and Newton's law, which is 3.29 with a high effect category. Sixth, based on the unit method, strategy, and model, the highest effect size is 2.19 with the category having a high impact on the student recap strategy.

Meta Analyses

In this meta-study, we analyzed 2,442 effect sizes from 131 meta-analyses in intelligence research, published from 1984 to 2014, to estimate the average effect size, median power, and evidence for bias. We found that the average effect size in intelligence research was a Pearson’s correlation of .26, and the median sample size was 60. Furthermore, across primary studies, we found a median power of 11.9% to detect a small effect, 54.5% to detect a medium effect, and 93.9% to detect a large effect. We documented differences in average effect size and median estimated power between different types of in intelligence studies (correlational studies, studies of group differences, experiments, toxicology, and behavior genetics). On average, across all meta-analyses (but not in every meta-analysis), we found evidence for small study effects, potentially indicating publication bias and overestimated effects. We found no differences in small study effects between different study types. We also found no convincing evidence for the decline effect, US effect, or citation bias across meta-analyses. We conclude that intelligence research does show signs of low power and publication bias, but that these problems seem less severe than in many other scientific fields.
