Children growing up in a dual-language environment have to constantly monitor the dynamic communicative context to determine what the speaker is trying to say and how to respond appropriately. Such self-generated efforts to monitor speakers' communicative needs may heighten children's sensitivity to, and allow them to make better use of, referential gestures to figure out a speaker's referential intent. In a series of studies, we explored monolingual and bilingual preschoolers' use of nonverbal referential gestures such as pointing and gaze direction to figure out a speaker's intent to refer. In Study 1, we found that 3- and 4-year-old bilingual children were better able than monolingual children to use referential gestures (e.g., gaze direction) to locate a hidden toy in the face of conflicting body-distal information (the experimenter was seated behind an empty box while the cue was directed at the correct box). Study 2 found that by 5 years of age, monolingual children had mastered this task. Study 3 established that the bilingual advantage can be found in children as young as 2 years old. Thus, the experience of growing up in a bilingual environment fosters the development of the understanding of referential intent. (Contains 1 table and 2 figures.)
