Infants infer and predict coherent event interactions: Modeling cognitive development.

Area of Science:

• Cognitive Science
• Developmental Psychology
• Computational Neuroscience

Background:

• Infant mental representations are initially sparse and become richer with development.
• Around 7 months, infants demonstrate goal-predictive gaze shifts for observed actions.
• Gaze prediction timing varies based on the actor (animate vs. inanimate).

Purpose of the Study:

• To introduce CAPRI2 (Cognitive Action PRediction and Inference in Infants), a computational model.
• To explain the developmental trajectory of goal-predictive gaze behavior in infants.
• To provide a functional and algorithmic perspective on infant action prediction.

Main Methods:

• Developed CAPRI2, a computational model based on event-predictive learning.
• Modeled infants' physical reasoning system and object file learning.
• Simulated CAPRI2 interpreting object interactions, maximizing event coherence, and minimizing uncertainty.

Main Results:

• CAPRI2 successfully mimics the developmental pathway of infant goal-predictive gaze behavior.
• The model demonstrates how infants infer goal-directed actions.
• Results align with findings on gaze shifts with animate vs. inanimate actors.

Conclusions:

• Event-predictive representations are crucial for developing goal-predictive capacities.
• Longer-term generative model learning and shorter-term inference principles are fundamental building blocks.
• CAPRI2 offers a framework for understanding infant cognitive development in action prediction.
