Adults' number gestures focus children on numeracy.

Area of Science:

• Cognitive Science
• Linguistics

Background:

• The

• problem highlights the challenge of word learning with infinite possibilities.
• Children learning number words may struggle to isolate numeracy as the relevant meaning.

Purpose of the Study:

• To investigate if number gestures help children focus on numeracy when learning number words.
• To determine if visual number cues aid in the acquisition of number concepts.

Main Methods:

• Two studies were conducted: a home-based observational study (N=64, ages 14-30 months) and a lab-based controlled study (N=112, ages 28-42 months).
• Natural parent-child interactions and controlled experimental conditions were used to assess responses to number words with and without gestures.

Main Results:

• Adult number words paired with number gestures elicited more child numeracy responses than number words alone in both studies.
• Children understood that a number response was expected when a gesture was present, even if they produced an incorrect number.
• The effectiveness of number gestures in focusing attention on numeracy was observed across different study settings.

Conclusions:

• Number gestures effectively cue children to the relevance of numeracy, similar to how color gestures cue color.
• These gestures have the potential to significantly focus attention on number concepts, thereby fostering early number acquisition.
• Number gestures act as a crucial scaffold in resolving the ambiguity inherent in early word learning for numerical concepts.
