Captions and subtitles were initially used in foreign language instruction in the 1980s, and some studies (Borras & Lafayette, 1994; Danan, 2004; Garza, 1991) have confirmed that combining captions with audio-visual materials is an effective instructional method to enhance the listening and reading comprehension of a second language as learners can confirm the information they hear by way of the support provided by the captions. In other words, captions visualize the auditory information of the foreign language which the learners hear in the video (Danan, 2004). Because of such additional cognitive processing, captions and subtitles promote language comprehension (Bird & Williams, 2002).
