The Role of Partial Knowledge in Question-Asking and Word Learning

Abstract

Children are active learners who seek information to reduce uncertainty, often by asking questions. However, recent research suggests that question-asking does not always lead to improved learning outcomes. The present study examined whether partial knowledge would promote question-asking and enhance word learning in preschool-aged children. To examine this, children aged 4 to 5 years (n = 37) were randomly assigned to either a pre-exposure (n = 23) or no pre-exposure (n = 14) condition. In a story-based task, children were asked to identify novel objects using unfamiliar labels, providing opportunities to ask questions during an exposure phase. Learning was then assessed through a delayed memory test. Contrary to predictions, children in the pre-exposure condition did not ask more questions than those in the no pre-exposure condition. Pre-exposure also did not significantly influence exposure-phase accuracy or delayed test performance. However, children performed significantly above chance on the delayed memory test, indicating successful learning overall. Question-asking occurred more frequently for novel than familiar objects but did not vary by condition or across trials. These findings suggest that providing a prior visual display of novel objects alone may not be sufficient to increase question-asking or improve learning outcomes. The results highlight the importance of identifying the conditions under which question-asking supports learning and how prior knowledge shapes children’s information-seeking behavior.
