In this quasi-experimental study, 165 learners of English for academic purposes at a university in China were randomly assigned to five experimental groups and a control group. Each experimental group encountered 19 target collocations in the same academic lecture in one of the following input modes: (a) reading, (b) listening, (c) reading while…

Research has indicated that first language (L1) English speakers acquire derivational knowledge--the ability to understand and produce derived forms of a word--through increased exposure to the language (e.g., Anglin, 1993). Second language (L2) research has shown that L2 English learners tend to have limited productive derivational knowledge in…

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…

The current study investigated the effects of repetition on the learning of second language (L2) spoken word forms. Japanese university students learning L2 English were randomly assigned to one of three treatment conditions (one, three, and six exposures) and learned 40 words while hearing them and viewing their corresponding pictures. A…

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…

Knowledge of English affixes plays a significant role in increasing knowledge of words. However, few attempts have been made to create a valid and reliable measure of affix knowledge. The Word Part Levels Test (WPLT) was developed to measure three aspects of affix knowledge: form (recognition of written affix forms), meaning (knowledge of affix…

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…

The Multimedia Principle (Fletcher & Tobias, 2005) states that people learn better and comprehend more when words and pictures are presented together. The potential for English language learners to increase their comprehension of video through the use of captions, which graphically display the same language as the spoken dialogue, has been…

This study investigated Vietnamese EFL learners' knowledge of verb-noun and adjective-noun collocations at the first three 1,000 word frequency levels, and the extent to which five factors (node word frequency, collocation frequency, mutual information score, congruency, and part of speech) predicted receptive knowledge of collocation. Knowledge…

This study investigates the effects of cognacy on vocabulary learning. The research expands on earlier designs by measuring learning of English-Japanese cognates with both decontextualized and contextualized tests, scoring responses at two levels of sensitivity, and examining learning in a more ecologically valid setting. The results indicated…

Previous research has furnished evidence that alliterative expressions (e.g. "a slippery slope") are comparatively memorable for second language learners, at least when these expressions are attended to as decontextualized items (Lindstromberg and Boers, 2008a; Boers et al., 2012). The present study investigates whether alliteration…
