Parents' multimodal spatial language structures infants' in-the-moment attention during spatial play

Area of Science:

• Developmental Psychology
• Cognitive Science
• Linguistics

Background:

• Understanding how caregivers scaffold infant attention is crucial for early cognitive development.
• Spatial language and gestures play a significant role in early learning and attention.
• Previous research has explored object labeling, but the combined impact of spatial language, object labels, and deictic gestures is less understood.

Purpose of the Study:

• To investigate how caregivers' use of spatial language, object labels, and deictic gestures influences infant attention during spatial play.
• To determine the effectiveness of multimodal input (speech + gestures) in scaffolding infants' in-the-moment attention.

Main Methods:

• Forty-nine caregivers and their 9-month-old infants participated in a spatial play task (puzzle).
• Caregivers' speech content (spatial words, object labels) and use of deictic gestures were analyzed.
• Infants' visual attention was tracked using head-mounted eye trackers during the play sessions.

Main Results:

• Caregivers' speech containing spatial words or object labels significantly increased infants' looking duration compared to speech without these elements.
• The combination of spatial language and object labeling was more effective in sustaining infant attention than either alone.
• The use of deictic gestures by caregivers further enhanced infants' attention duration, underscoring the importance of multimodal communication.

Conclusions:

• The content of caregivers' speech, specifically spatial terms and object labels, is vital for capturing and maintaining infant attention.
• Multimodal communication, integrating verbal input with deictic gestures, provides robust scaffolding for infants' real-time attention.
• These findings contribute to understanding how early social interactions shape infants' attentional development.
