The involvement load hypothesis (ILH) was designed to predict the effectiveness of instructional tasks for incidental L2 vocabulary learning. In this meta-analysis we examined 398 effect sizes from 42 empirical studies (N = 4,628) to explore (a) the overall predictive ability of the ILH, (b) the relative effects of different components of the ILH…

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…

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…

Television is considered an important source of comprehensible input for second language learners of English and there is some evidence that L2 words can be learned incidentally by watching television. Few studies have looked at the role of TV viewing for learning formulaic sequences, despite the ubiquity of formulaic sequences in spoken English,…

Shared-book reading is a well-established intervention to foster vocabulary development. Factors influencing its effectiveness are, however, less well studied, particularly with regard to story-delivery. We contrasted a read-aloud with a free storytelling approach and tested effects on vocabulary learning. In the first study, 83 preschoolers aged…

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest-posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and…

The relationship between placement of adjunct questions in instructional material and incidental and intentional learning was investigated. A total of 150 undergraduate students assigned to five experimental groups studied ten paragraphs with questions interspersed at different locations in the text. Performance on incidental items was…
