This study is aimed to identify the effects of task complexity on first language (L1) use and the functions it may serve when two groups of learners of English as a foreign language (EFL) work on collaborative tasks. Twenty-four pairs of Chinese EFL learners from two universities were assigned to a lower-proficiency and a higher-proficiency group,…

The involvement load hypothesis (ILH), which predicts the lexical learning potential of tasks, assumes that writing sentences (SW) and compositions (CW) using novel target words (TWs) lead to similar lexical gains. However, research on the issue is scarce and contradictory. One possibility is that the higher cognitive load of CW hinders learning…

Instructed second language acquisition (ISLA) research has recently attracted more focal attention due to the publications of three books and as the theme of the 2016 Second Language Research Forum (SLRF) conference that celebrated its 35th anniversary in the field of second language acquisition (SLA). Recent definitions (e.g. Loewen, 2015) have…

The use of concurrent data elicitation procedures (e.g. think-alouds, eye-tracking, response time) to investigate learners' cognitive processing and processes is becoming more prominent in research designs as researchers seek to acquire a better understanding of how second language (L2) learners process L2 data (e.g. Martin et al., 2019; Rogers,…

This article reports on a study in which stimulated recall data and quantitative measures of complexity, accuracy and fluency (CAF) were used to address three interconnected questions in different planning conditions: (1) how learners share their limited attentional capacity with different cognitive processes of 'planner/proposer', 'translator'…

From an information processing perspective, humans have a limited attentional capacity for processing information. Thus, second language (L2) researchers have investigated the role of pretask planning in task performance, finding that planning results in greater fluency and complexity but has mixed effects on accuracy. However, most planning…

The Keyword Method (KWM) of vocabulary learning is a mnemonic method designed to help students learn foreign vocabulary. It has been shown to be effective over several other memorization strategies. The present experiment was designed to explore the cognition underlying the effectiveness of the KWM. Specifically, both the degree of cognitive…
