Eighty Japanese learners of English as a foreign language encountered 40 target words in one of four experimental conditions (three encounters, six encounters, three encounters with talker variability, and six encounters with talker variability). A picture-naming test was conducted three times (pretest, immediate posttest, and delayed posttest)…

There has been little research investigating how mode of input affects incidental vocabulary learning, and no study examining how it affects the learning of multiword items. The aim of this study was to investigate incidental learning of L2 collocations in three different modes: reading, listening, and reading while listening. One hundred…

This study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence--size, organization, and accessibility--and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three…

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…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

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…

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…

Investigating the impact of linguistic characteristics on visual word recognition in children, we studied whether differences in native (L1) and second language (L2) processing already emerge at the beginning of reading development. German elementary school students in grades 2 to 6 completed a battery of standardized tests and a lexical decision…

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…

Although expanding spacing is often regarded as the most effective practice schedule, studies comparing equal and expanding spacing have yielded mixed results. The present study set out to examine whether the amount of spacing and the retention interval may influence the effects of expanding and equal spacing on second language (L2) vocabulary…

Improvement in second-language (L2) perception has been posited to occur early in L2 learning when the L2 vocabulary is still small, whereas a large L2 vocabulary curtails perceptual learning (the perceptual assimilation model for SLA [PAM-L2]; Best & Tyler, 2007). This proposition is extended by suggesting that early L2 lexical development…

This study investigated the relationship between phonological memory and second language (L2) fluency gains in native English-speaking adults learning Spanish in two learning contexts: at their home university or abroad in an immersion context. Phonological memory (operationalized as serial nonword recognition) and Spanish oral fluency…

In a study of language anxiety, a video camera was introduced at various points in a vocabulary learning task. Observations of first-year university students of French revealed significant increases in anxiety when the camera was introduced, along with concomitant deficits in vocabulary acquisition. Implications for remedial action are discussed.…

Investigated the effects of text modification and task on incidental learning of foreign-language vocabulary by reading. The study focuses on how different cue types and a task would affect processing of input, initial learning, and retention of the meaning of target words. Results indicate that single and multiple-choice marginal gloss conditions…
