Young children communicate their ignorance and ask questions

Area of Science:

• Developmental Psychology
• Cognitive Science
• Child Development

Background:

• Children learn cultural information by listening to others.
• Young children are selective learners, favoring information from culturally representative informants.
• The extent to which children actively exploit information transmission to fill knowledge gaps is under-investigated.

Purpose of the Study:

• To investigate if toddlers understand information transmission processes.
• To determine if children actively exploit information transmission to fill knowledge gaps.
• To review evidence of toddlers' expressive behaviors when facing knowledge gaps.

Main Methods:

• Review of existing evidence on toddlers' behaviors when knowledge gaps are present.
• Analysis of expressive behaviors including looking toward adults, nonverbal gestures (e.g., shrugs), and verbal acknowledgments of ignorance ('I don't know').
• Examination of toddlers' production of comments, questions about interlocutors' knowledge, and adoption of an interrogative stance.

Main Results:

• Toddlers exhibit various expressive behaviors when faced with knowledge gaps.
• Children in their second and third years actively seek information via nonverbal gestures and verbal questions.
• Sought-after information shows a heightened tendency for encoding and retention by young children.

Conclusions:

• Toddlers actively seek information from interlocutors to address their own knowledge deficits.
• Children demonstrate an understanding of information transmission and utilize it to acquire knowledge.
• This active information seeking and retention is crucial for cultural learning and cognitive development.
