Direct linkBelia, Margherita; Keren-Portnoy, Tamar; Vihman, Marilyn – Language Learning, 2023
This systematic review surveyed research on the associations between sleep and the memory processes involved in word learning in infancy. We found only 16 studies that addressed this topic directly, identifying associations between infant sleep and the memory processes, the identification of word forms in running speech, and the stabilization and…

Lee, Jang Ho; Lee, Hansol – Language Learning, 2022
This article reports a meta-analysis of studies on the effects of teachers' verbal lexical explanation (TVLE), as one type of lexical focus on form, on second language vocabulary learning. The dataset for this meta-analysis included 14 studies, representing a total of 36 independent samples (N = 3,304). The results of this study reveal that TVLE…

Yanagisawa, Akifumi; Webb, Stuart – Language Learning, 2021
The involvement load hypothesis (ILH) was designed to predict the effectiveness of instructional tasks for incidental L2 vocabulary learning. In this meta-analysis we examined 398 effect sizes from 42 empirical studies (N = 4,628) to explore (a) the overall predictive ability of the ILH, (b) the relative effects of different components of the ILH…

Uchihara, Takumi; Webb, Stuart; Yanagisawa, Akifumi – Language Learning, 2019
This meta-analysis aimed to clarify the complex relationship between repetition and second language (L2) incidental vocabulary learning by meta-analyzing primary studies reporting correlation coefficients between the number of encounters and vocabulary learning. We synthesized and quantitatively analyzed 45 effect sizes from 26 studies (N = 1,918)…

de Vos, Johanna F.; Schriefers, Herbert; Nivard, Michel G.; Lemhöfer, Kristin – Language Learning, 2018
We meta-analyzed the effectiveness of incidental second language word learning from spoken input. Our sample contained 105 effect sizes from 32 primary studies employing meaning-focused word-learning activities with 1,964 participants with typical cognitive functioning. The random-effects meta-analysis yielded a mean effect size of g = 1.05,…

Jeon, Eun Hee; Yamashita, Junko – Language Learning, 2014
The present meta-analysis examined the overall average correlation (weighted for sample size and corrected for measurement error) between passage-level second language (L2) reading comprehension and 10 key reading component variables investigated in the research domain. Four high-evidence correlates (with 18 or more accumulated effect sizes: L2…
