Six- and 9-Month-Old Infants Discriminate Between Goals Despite Similar Action Patterns

Area of Science:

• Developmental Psychology
• Cognitive Development
• Infant Social Cognition

Background:

• Previous research indicated 9- to 18-month-old infants differentiate actor intentions (unwilling vs. unable to share).
• 6-month-old infants did not show this differentiation in prior studies.
• Visual habituation studies suggest earlier onset of goal awareness than behavioral tasks.

Purpose of the Study:

• To reconcile conflicting findings on the onset of infant goal awareness.
• To replicate and extend previous findings on infant intention understanding.
• To investigate 6- and 9-month-olds' ability to differentiate actor goals in a sharing context.

Main Methods:

• Replication of tasks used by Behne et al. (2005).
• Inclusion of both 6- and 9-month-old infant participants.
• Utilized similar tasks with the addition of novel response measures.

Main Results:

• Findings suggest that 6-month-olds, similar to 9-month-olds, can differentiate between actors unwilling and unable to share.
• The study observed differences in infant responses based on the actor's goal, not just the outcome.
• Additional response measures provided clearer evidence of intention attribution in younger infants.

Conclusions:

• Infant understanding of intentionality in social interactions emerges earlier than previously suggested by some behavioral tasks.
• 6-month-olds demonstrate sensitivity to the goals of others in a toy-sharing scenario.
• The findings contribute to a more nuanced understanding of early cognitive development and social cognition.
