Impact of language familiarity on abstract pattern recognition in 9- to 12-month-old infants

Previous studies found an impact of language familiarity on face recognition in 9- and 12-month-olds. Own race faces are better recognized when associated with native language, whereas for other race faces, it is with non-native language. The aim of this study is to investigate if language familiarity can also influence abstract pattern recognition. We tested 9- to 12-month-old monolingual infants with a visual paired-comparison task. During a 30-s familiarization phase, infants were shown an image of abstract patterns associated with an auditory soundtrack of a speaker reciting a story either in their native (French) or in a non-native language (German). After the familiarization, the familiar and a new abstract pattern were displayed side by side for the recognition test. We found a significant preference for the novel object in the native language condition but not in the non-native condition. These results suggest that language familiarity effects on infant memory are not specific to faces but also influence, on a larger scale, how infants process their immediate visual environment.
