This article provides a conceptual review of the principles of input spacing as they might relate specifically to oral task repetition research and presents some of the common methodological considerations from the broader input spacing literature. The specific considerations discussed include the interaction between intersession intervals and…

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)…

This study aimed to investigate which word-related variables play a role in Dutch-speaking children's L2 word learning through out-of-school exposure prior to classroom instruction in the foreign language. We used different measures to investigate the role of frequency, concreteness, cognateness, and age of acquisition (AoA) in receptive…

This cross-sectional study investigated the impact of length of instruction, out-of-school exposure to foreign language input, and gender on learners' receptive vocabulary knowledge in two foreign languages: French (first foreign language) and English (second foreign language). The findings suggest that, although length of instruction correlated…

We investigated the potential influence of implicit learning mechanisms on L2 morphosyntactic attainment by examining the relationship between age of onset (AoO), two cognitive abilities hypothesized to underlie implicit learning (phonological short-term memory and implicit statistical learning), and performance on an auditory grammaticality…

This study investigated order-of-learning effects on the acquisition of classifier-noun associations in Chinese in two experiments modeled after Arnon and Ramscar's (2012) study of artificial language learning. In Experiment 1, learners with no prior exposure to Chinese showed better learning of classifier-noun associations when exposed to larger…

This study uses conversation analysis (CA) to investigate the coupling of specific linguistic items with specific gestures in second language (L2) learning over time. In particular, we are interested in how gestures accompany learning of new vocabulary. CA-informed studies of gesture have previously shown the importance of embodiment in L2 use and…

Over the past several decades, researchers have discovered a great deal of information about the processes underlying language acquisition. From as early as they can be studied, infants are sensitive to the nuances of native-language sound structure. Similarly, infants are attuned to the visual and conceptual structure of their environments…

Drawing on a large corpus of video-recorded classroom data, the goal of this study was to understand the processes and mechanisms associated with learning in individuals who have had little education in their home countries. In order to accomplish this goal, we measured the socio-interactive behaviors and the expression of personality behaviors in…

The article by Carota and Sirigu addresses a fundamental issue, namely the domain specificity of people's ability to learn and implement sequential structures of events. The authors review theoretical positions and empirical findings related to this issue, providing a useful summary of representative models of sequential event structures, and a…
