Retrieval practice of isolated words (e.g., with flashcards) enhances foreign vocabulary learning. However, vocabulary is often encountered in context. We investigated whether retrieval opportunities also enhance contextualized word learning. In two within-subjects experiments, participants encoded 24 foreign words and then read a story to further…

One of the major challenges for any L2 teacher is to integrate vocabulary components into a course. Determining what words to select in order to satisfy the goals of the course and what instructional methodology best suits the purpose of vocabulary learning are not easy tasks. Even more difficult is dealing with the formulaic terminology of a…

In recent years, the number of studies investigating the effectiveness of using digital games for incidental second language (L2) vocabulary learning has been rapidly increasing; however, there is still a lack of research identifying the factors that affect incidental L2 vocabulary learning. Hence, the current study examined vocabulary-related…

Working memory (WM) may be an essential component of incidental vocabulary learning and retention from captioned videos. However, how WM affects young learners' incidental vocabulary learning under different types of captions remains unclear. The present study employs a between-subject research design. The main purpose is to examine how two types…

The aim of this study is to analyze the effect of different schedules of repeated reading practice on intentional vocabulary learning, and constitutes a partial replication and extension of the authors' previous study on incidental vocabulary learning. Two groups of Taiwanese EFL learners (n = 72) engaged in five repeated reading sessions; one…

The authors examined the influence of context meaning consistency on incidental vocabulary acquisition during reading. "Context meaning consistency" refers to informational context that reflected the same meaning (i.e., consistent) or different meanings (i.e., inconsistent) across two self-paced reading sessions for a given item (both…

Semantic knowledge accumulates through explicit means and productive processes (e.g., analogy). These means work in concert when information explicitly acquired in separate episodes is integrated, and the integrated representation is used to self-derive new knowledge. We tested whether (a) self-derivation through memory integration extends beyond…

This article reviews the empirical research on incidental vocabulary acquisition in English reading in the latest twenty years from three aspects: its comparison with intentional vocabulary acquisition, its affecting factors and previous studies of its problems. Teaching implications have also been provided.

This study investigated the effects of processing three types of texts, namely expository texts, narrative texts, and a combination of both known as twin texts, on incidental vocabulary acquisition and retention in L2 learners. College freshmen (N = 109), who were lower to upper intermediate learners of English, were assigned into a control group…

People make inferences about the trustworthiness of others based on their observed gaze behavior. Faces that consistently look toward a target location are rated as more trustworthy than those that look away from the target. Representations of trust are important for future interactions; yet little is known about how they are consolidated in…

The research on incidental vocabulary acquisition through reading has claimed that repeated encounters of unfamiliar words and the context in which these words occur facilitate word learning. However, so far both variables have been investigated in isolation. This study was conducted to explore the impact of context types, word occurrence…

Acquiring and retaining vocabulary knowledge are two of the most important aspects of second language (L2) learning. Some scholars (e.g. Hedrick, Harmom, & Linerode, 2004; Nation, 1999; Stone & Urquhart, 2008) advocate that we should re-think and explore in depth the importance of vocabulary. According to Wilkins (1972), "while…

The purpose of this study was to investigate whether intentional vocabulary learning, incidental vocabulary learning, or a combination of the two best prepares students for learning and retaining vocabulary in English as foreign language learning (EFL) classrooms. Three experimental groups and three control groups were selected. All groups were…

Focus on form (FonF) studies have predominantly addressed its effectiveness in improving learners' syntactic, lexical, orthographic, and phonological knowledge. Extending the scope of this line of research to formulaic FonF practices, this study investigates the relative effectiveness of incidental FonF targeting formulaic versus nonformulaic…

Previous studies on lexical focus on form (FonF) have mostly centred on FonF in reading with a few pre-selected lexical items. This study investigated the contribution of oral incidental FonF to developing learners' lexical knowledge in a free discussion EFL class. Incidental FonF was provided to 15 upper-intermediate learners who participated in…
