Factors That Influence Fast Mapping in Children Exposed to Spanish and English

Abstract

Purpose The purpose of this study was to determine whether children exposed to 2 languages would benefit from the phonotactic probability cues of a single language in the same way as monolingual peers and to determine whether crosslinguistic influence would be present in a fast-mapping task. Method Two groups of typically developing children (monolingual English and bilingual Spanish-English) took part in a computer-based fast-mapping task that manipulated phonotactic probability. Children were preschool-aged ( N = 50) or school-aged ( N = 34). Fast mapping was assessed through name-identification and naming tasks. Data were analyzed using mixed analyses of variance with post hoc testing and simple regression. Results Bilingual and monolingual preschoolers showed sensitivity to English phonotactic cues in both tasks, but bilingual preschoolers were less accurate than monolingual peers in the naming task. School-aged bilingual children had nearly identical performance to monolingual peers. Conclusion Knowing that children exposed to two languages can benefit from the statistical cues of a single language can help inform ideas about instruction and assessment for bilingual learners.
