Bilingual Lexical Access and Cognate Idiom Comprehension (2020)

Abstract: Language transfer can facilitate learning L2 words whose form and meaning are similar to L1 words, or hinder speakers when the languages differ. L2 idioms introduce another layer of challenge, as language transfer could occur on the literal or figurative level of meaning. Thus, the mechanics of language transfer for idiom processing shed light on how literal and figurative meaning is stored in the bilingual lexicon. Three factors appear to influence how language transfer affects idiom comprehension: bilingual fluency, processing of literal-figurative vs. figurative cognate idioms (idioms with the same wording and meaning in both languages, or the same meaning only), and comprehension of literal vs. figurative meaning of a given idiom. To examine the relationship between these factors, this study investigated English-Spanish bilinguals’ reaction time on a lexical decision task examining literal-figurative and figurative cognate idioms. The results suggest that fluency increases processing speed rather than slow it down due to language transfer, and that language transfer from L1 to L2 occurs on the level of figurative meaning in L1-dominant bilinguals.

## introduction speakers learning a new language may be helped or hindered by similarities with their native language. language transfer-the influence of a speaker's native language (l1) on the new language (l2)-can facilitate learning l2 words whose form and meaning are similar to l1 words, but can confuse speakers when the languages differ (as with false cognates). thus, understanding the mechanics of language transfer helps to illuminate potential difficulties for language learners. l2 idioms introduce another challenge, as idioms have both a literal meaning and a figurative one that cannot be fully decomposed from the meanings of the individual words. whereas experiments involving non-idiom words have investigated language transfer between the visual forms and the literal meanings of words, idioms introduce a third level on which language transfer may occur: that of figurative meaning. the effects of language transfer provide key insight into questions of idiom representation in the bilingual lexicon. although some argue that idioms are stored as unanalyzable, fixed units in the lexicon, other studies have suggested hybrid models of idiom compositionality in which idioms may be interpreted both figuratively and literally to different extents depending on factors such as a speaker's familiarity with the idiom @xcite . recent studies have investigated how bilingual fluency affects the degree to which literal and figurative meanings are activated during lexical access. l2 learners generally develop the ability to understand the literal meanings of l2 idioms before they can understand their figurative meanings. other studies preliminarily suggest that language transfer helps l1-dominant bilinguals with comprehension of l2 cognates but may in fact slow down l2-dominant bilinguals (see section 2). three factors appear to influence how language transfer affects idiom comprehension: bilingual fluency, processing of literal-figurative vs. figurative cognate idioms (idioms with the same wording and meaning in both languages, or with only the same meaning), and comprehension of literal vs. figurative meaning of a given idiom (figure 1 ). previous work has only examined some relationships between these factors, but none have examined either (1) the relationship between bilingual fluency and the processing of literal-figurative and figurative cognate idioms or (2) comprehension of literal vs. figurative meaning for literal-figurative and figurative cognate idioms. this study examines both of those questions by measuring the relationship between bilingual fluency and the speed of processing literal vs. figurative meaning for literal-figurative and figurative cognate idioms. the relationship between processing speed and fluency for different idiom types (literal-figurative cognate or figurative cognate) and target types (literal or figurative processing) shines light on whether increased fluency indeed affects comprehension of literal-figurative cognates compared to figurative cognates, and whether language transfer affects literal or figurative processing more significantly. this study began with the hypothesis that l1-dominant bilinguals would process l2 cognate idioms more quickly than non-cognates, but l2-dominant bilinguals would not, as @xcite proposed that language transfer slows down processing as fluency increases (see section 2). it was also hypothesized that processing of literal meaning, as well as processing of figurative meaning, would become faster as fluency increased-i.e., that there is no tradeoff between comprehension of figurative and literal meaning-in keeping with the argument that the literal meanings of idioms, not only figurative ones, may be stored in the bilingual lexicon to some extent. the results suggest that, contrary to heredia et al.'s hypothesis, fluency sped up processing rather than slow it down because of language transfer. more strikingly, they also suggest that language transfer from l1 to l2 occurs on the level of figurative meaning in l1-dominant bilinguals. ## related work language transfer occurs when a speaker's native language influences the acquisition or use of their l2; in particular, it affects the processing of cognate words between the speaker's l2 and l1. bilinguals process l2 words with l1 cognates more quickly than l2 words without l1 cognates and are more accurate at mapping form to meaning for cognates, but tend to process false friends (l2 words visually or phonetically similar to l1 words but with different meanings) more slowly @xcite . thus, language transfer may increase or decrease processing speed depending on whether the forms and meanings of words are aligned between two languages. unlike expressions whose meaning can be decomposed from the meanings of individual words, the meaning of idioms is at least partially non-compositional. thus, idioms may have a literal meaning (kick the bucket as in touching a pail with a foot) alongside a figurative one (to die), 1 both of which may be literal-figurative cognate figurative cognate spanish idiom tirar la toalla de tal palo, tal astilla throw the towel from such stick, such splinter english equivalent throw in the towel the apple doesn't fall far from the tree figurative meaning "give up" "the child is similar to the parent" idioms in two languages may be cognates with respect to their literal and/or figurative meanings ( two similar studies suggest that language transfer helps l1-dominant bilinguals with comprehension of l2 cognates but slows down l2-dominant bilinguals. @xcite found that spanish-dominant bilinguals were more accurate at comprehending literal-figurative cognate idioms in english than non-cognate english idioms. however, @xcite found that, surprisingly, english-dominant english-spanish bilinguals were slower at reading literal-figurative cognate idioms in english than figurative cognate idioms. @xcite suggested that language transfer between literally similar english and spanish idioms might slow down bilinguals as they become more fluent in their l2 (english): whereas different idioms might be stored as single words, literally similar idioms might activate both l1 and l2 lexicons, slowing down processing. however, because heredia et al. did not examine spanish-dominant bilinguals, and irujo did not examine english-dominant bilinguals, there remains the open question of the extent to which language transfer confers an advantage or disadvantage on the processing of literalfigurative cognate idioms as bilingual fluency increases. some studies have investigated the relationship between bilingual fluency and the comprehension of literal and figurative meaning, while others have investigated the differences between bilingual processing of literal-figurative and figurative cognate idioms. the relationship between bilingual fluency and the processing of literal and figurative cognate idioms, as well as the comprehension of literal vs. figurative meaning for literal-figurative and figurative cognate idioms, have remained open questions. to address them, this study examines the relationship between bilingual fluency and processing of literal vs. figurative meaning for literal-figurative and figurative cognate idioms.
