Helpless infants are learning a foundation model

Area of Science:

• Developmental neuroscience
• Cognitive science
• Machine learning

Background:

• Humans exhibit a prolonged postnatal helplessness period, often linked to early birth and immature brain development.
• Comparative neurodevelopment suggests human infants' brains at birth are not uniquely immature compared to species with shorter helplessness.
• Infant neuroimaging reveals significant similarities between newborn and mature brain connectivity and functional activation.

Purpose of the Study:

• To challenge the notion of uniquely immature human infant brains at birth.
• To propose a novel framework for understanding early human cognitive development.
• To draw parallels between infant learning and machine learning foundation models.

Main Methods:

• Comparative analysis of neurodevelopmental timelines across species.
• Review of findings from infant neuroimaging studies.
• Conceptual framework inspired by machine learning foundation models.

Main Results:

• Human infants' neurodevelopmental timing is comparable to other species, despite a longer period of helplessness.
• Newborn brain connectivity and function show remarkable similarities to mature brains.
• The infant's extended postnatal period can be viewed as a 'pre-training' phase.

Conclusions:

• Human infants are learning a foundation model, acquiring fundamental representations for cognition.
• This learning process supports high cognitive performance and rapid generalization.
• The concept of a 'helpless period' is re-framed as a critical learning phase for developing cognitive abilities.
