In paired-associate learning, there are two learning directions: L2 to L1 (L2 words as stimuli and L1 words as responses) and L1 to L2 (L1 words as stimuli and L2 words as responses). Results of previous studies that compared the effects of the two learning directions are not consistent. We speculated that the cause of this inconsistency may be L2…

Although retrieval of lexical forms is a prerequisite for language production, research of L2 vocabulary learning has focused much more on meanings and form-meaning mappings than on development of detailed, accessible mental representations of forms. This is particularly true with respect to multi-word items (MWIs). We report an experimental study…

This study combines explicit (pen-and-paper) and sensitive (time-pressured) measures to gauge the impact of three instructional interventions (contextualized input with meaning-focused activities, contextualized input with word-focused activities, and decontextualized input with word-focused exercises) on the learning of 20 L2 French target verbs.…

This longitudinal study investigates the effect of mode of reading on the incidental learning of collocations and factors that affect learning. One hundred Vietnamese pre-intermediate learners of English as a foreign language (EFL) were assigned to either an experimental group or a control group (no treatment). In 9 weeks, the experimental group…

This study is a conceptual replication of Rogers and Cheung's (2018) investigation into distribution of practice effects on the learning of L2 vocabulary in child EFL classrooms in Hong Kong. Following a pretest, treatment, delayed posttest design, 66 primary school students (Cantonese L1) studied 20 vocabulary items over three training episodes…

Academic lectures are potential sources of vocabulary learning for second language learners studying at universities where English is the medium of instruction, as well as those in English for Academic Purposes (EAP) programs. Topic-related vocabulary is likely to occur frequently in academic texts, and academic speech consists of a reasonable…

Sixty target words were selected from two sets of graded readers. One set contained three readers with the same title, "The Railway Children," and the other set, three books about Sherlock Holmes. Students chose one of the two sets to read and were given a pretest, an immediate posttest, and a five-week delayed posttest on their…

This meta-analysis investigated the overall effects of glossing on L2 vocabulary learning from reading and the influence of potential moderator variables: gloss format (type, language, mode) and text and learner characteristics. A total of 359 effect sizes from 42 studies (N = 3802) meeting the inclusion criteria were meta-analyzed. The results…

Although researchers argue that studying semantically related words simultaneously (semantic clustering) inhibits vocabulary acquisition, recent studies have yielded inconsistent results. This study examined the effects of semantic clustering while addressing the limitations of previous studies (e.g., confounding of semantic relatedness with other…

The study examined the predictions of regulatory fit theory (Higgins, 2000) in relation to task-based incidental vocabulary learning. A total of 189 English as a second language learners completed a vocabulary pretest, a regulatory focus questionnaire, an integrated reading/writing task, and finally an unannounced vocabulary posttest. The…

The present study explores the incidental learning of formulaic sequences (FS) from audio-visual input and factors affecting the learning of FS. A pretest-posttest, within-participant design was adopted. English-as-a-foreign-language learners (L1 = Dutch; n = 42) watched a one-hour English-language documentary without subtitles. Learning gains…

The present study brings together methods of extensive reading studies and eye-movement research to track the cognitive effects of exposure frequency on vocabulary processing and learning. Forty-two advanced second language learners of English read a stage 1 graded reader, "Goodbye Mr. Hollywood," on a computer screen while their eye…

Sixty English as a foreign language learners were divided into high-, intermediate-, and low-level groups based on their scores on pretests of target vocabulary and Vocabulary Levels Test scores. The participants read 10 Level 1 and 10 Level 2 graded readers over 37 weeks during two terms. Two sets of 100 target words were chosen from each set of…

This study used a pretest-posttest-delayed posttest design at one-week intervals to determine the extent to which written, audio, and audiovisual L2 input contributed to incidental vocabulary learning. Seventy-six university students learning EFL in China were randomly assigned to four groups. Each group was presented with the input from the same…
