The study investigates the development of children's talker recognition abilities. The findings suggest that early developmental improvements are primarily influenced by specific knowledge in familiar languages, with limited enhancement in unfamiliar languages.
Previous studies have shown that talker recognition by young children continues to improve into late childhood. But why might this be the case? Are children's gradually improving talker recognition abilities driven primarily by general maturational factors in the cognitive or perceptual domain (general maturation hypothesis), or are these improvements primarily linked to children's increasingly sophisticated linguistic knowledge (language attunement hypothesis)? In the current study, we addressed this question by testing monolingual English-speaking 5- and 6-year-olds (N = 80) on their ability to recognize talkers in a familiar language (i.e., English) and in an unfamiliar language (i.e., Spanish) using a voice lineup talker recognition task. We predicted two alternative outcomes. According to the general maturation hypothesis, we should see improvements in talker recognition for both the familiar and unfamiliar languages as children grow older. According to the language attunement hypothesis, however, we should see developmental improvements in talker recognition for the familiar language only. Our findings suggest that early developmental improvements in talker recognition are limited to familiar languages, highlighting the potential central role of language specific knowledge in talker recognition.
