Despite extensive theoretical and empirical research, we do not have estimations of the magnitude of sensitivity to grammatical information during L2 online processing. This is largely due to reliance on null hypothesis significance testing (Plonsky, 2015). The current meta-analysis draws on data from one elicitation technique, self-paced reading,…

This study partially replicates McManus and Marsden (2017), who found that providing L1 explicit information (EI) plus task-essential practice led L2 learners to make more accurate and faster interpretations of French morphosyntax. The current study removed the original study's L1 EI component to examine the role of the L1 practice. This design…

Illustrates the advantages of laboratory research into second language acquisition (SLA) by describing two studies of acquisition of second language syntax. The first, conducted in Wales, addresses the question of whether human morphological abilities can be understood in terms of associative processes, and the second presents a bootstrapping…

Investigates the interaction between the presence or absence of explicit instruction and the variables complexity and morphology/syntax in the acquisition of four second language (L2) structures. Results from computer-controlled posttests confirm the hypothesis that explicit instruction facilitates the acquisition of L2 grammar. (66 references)…
