Action Prediction Allows Hypothesis Testing via Internal Forward Models at 6 Months of Age

Area of Science:

• Cognitive Development
• Developmental Psychology
• Embodied Cognition

Background:

• Internal forward models are crucial for learning and predicting actions.
• Infants' predictions of actions are validated or falsified by perceived outcomes.
• Action prediction and evaluation are linked to understanding social interactions.

Purpose of the Study:

• To investigate the role of action prediction in infants' learning processes.
• To explore the correlation between action prediction and action evaluation in 6-month-old infants.
• To examine the relationship between action prediction latency and manual proficiency in infants.

Main Methods:

• An individual differences approach was used with a large sample of 118 infants.
• Infants' action predictions were observed and correlated with their reactions to unexpected social interactions.
• Analysis included correlating prediction latency with infant manual proficiency.

Main Results:

• Action prediction significantly correlates with the tendency to show surprise at unexpected social interactions.
• This association was observed across various tasks in 6-month-old infants.
• Infants' action prediction latency is correlated with their own manual proficiency.

Conclusions:

• Infants may utilize internal forward models to interpret and structure their social world.
• Action prediction appears to be a foundational element in early social learning.
• Motor development and predictive processing are interconnected in early infancy.
