This exploratory study investigates the effects of imagery on word learning through audio-visual input. A total of 82 adolescent EFL learners were exposed to 8 episodes of a TV series under four conditions, depending on the language of the on-screen text (L1 or L2) and whether they were pre-taught target words or not. The effects of co-occurrence of the word with its image, and the image time on screen (ITOS) were explored, alongside frequency, proficiency, and learning condition variables. Results showed that both image-related variables and frequency predicted word-form learning, while only ITOS predicted word-meaning recall, with a longer exposure to image associated to higher gains, suggesting that, at this age and proficiency level, the images associated with the words can be conducive to learning.

This article addresses the benefits of audio-visual input for learning second language (L2) vocabulary and grammatical constructions. Specifically, it explores the role of frequency, the effects of subtitles and captions, and the mediating role of learner proficiency on language gains in two longitudinal studies. Study 1 targets vocabulary acquisition in two groups of adolescents with an elementary L2 proficiency level who view 24 episodes of a TV series spread weekly over a whole academic year, one group with subtitles (first language) and one with captions (second language). Study 2 targets grammar acquisition in two groups of university students with an intermediate proficiency level who view 10 episodes over five weeks, one group with captions and one without captions. Results of both studies show significant correlations between language gains and frequency in the input, but the size of the frequency effect appears to depend on the type of support provided by the on-screen text. The analyses also show no significant advantage of captions or subtitles for vocabulary learning at this proficiency level, a significant advantage of captions over no captions for grammatical constructions learning, as well as the significant role of proficiency. It is concluded that viewing audio-visual material leads to L2 learning and it can support learners in their preparation for study abroad and maximize their learning experience during their sojourn.

This study explores the differential effects of captions and subtitles on extensive TV viewing comprehension by adolescent beginner foreign language learners, and how their comprehension is affected by factors related to the learner, preteaching of target vocabulary, the lexical coverage of the episodes, and the testing instruments. Four classes of secondary school students took part in an 8-month intervention viewing 24 episodes of a TV series, two classes with captions, and two with subtitles. One class in each language condition received explicit instruction on target vocabulary. Comprehension was assessed through multiple-choice and true-false items, which included a combination of textually explicit and inferential items. Results showed a significant advantage of subtitles over captions for content comprehension, and prior vocabulary knowledge emerged as a significant predictor—particularly in the captions condition. Comprehension scores were also mediated by test-related facto...

This study explores the effects of L1 syntactic complexity, L2 proficiency and L2 learning background on L2 syntactic complexity in oral performance. Syntactic complexity has shown to be an important concept in SLA research due to the assumption that language development entails, among other processes, the growth of the L2 syntactic repertoire as speakers become more proficient in their L2 (Ortega, 2009). Research has also shown that there is a relationship between different L1 skills and L2 performance (e.g. Cummins, 1979, 1984; Proctor et al., 2006; Sparks et al., 2009; Verhoeven, 1994), and that there could be no fundamental difference between L1 and L2 production process (Kormos, 2006). Thus, the use of more complex syntactic features may depend, besides L2 proficiency, on individual differences in the L1 and the transfer of a preference for a specific syntactic structure from L1 to L2 (Ortega, 2003). The present study seeks to investigate whether L1 syntactic complexity would p...

This doctoral dissertation explores the benefits of an extensive exposure to L2 television for content comprehension and vocabulary learning with beginner, adolescent EFL learners, through a longitudinal classroom-based intervention. The study also aims at investigating the role of frequency and imagery in word learning, and evaluating the long-term effects this type of intervention may have on learners’ attitudes towards the use of L2 television for language learning purposes. In order to do so, several aspects were examined, including factors related to the intervention, the learner, and the input itself. Four classes of Grade 8 students viewed 24 consecutive episodes of a TV series – spaced over an academic year – under four experimental conditions, with each class being assigned to a different treatment. Two classes viewed the episodes with English [L2] captions, and two with Spanish [L1] subtitles. One class in each language condition received, additionally, explicit instructio...
