Abstract:
The present study was an endeavor to investigate the effectiveness of English full and keyword captions in comparison to Farsi full and keyword subtitles and no caption with regard to English language learners’ listening comprehension and incidental vocabulary acquisition. For this purpose, 76 English as a foreign language (EFL) learners at Sharif University of Technology from five intact classes were assigned to each condition. Preliminary English test was administered to measure learners’ listening performance before and after the treatment. Researcher-made vocabulary tests based on the difficult words that were captioned in the videos were included in vocabulary tests. The treatment lasted for three sessions. The results for listening comprehension indicated the superiority of keyword caption over full caption in English, with neither of Farsi subtitles being found ineffective. As for incidental vocabulary acquisition, it was found that English captions functioned better than the Farsi subtitles. These findings are discussed in light of learners’ processing capacities and implications are provided
