Symbolic Closure and the Neurodevelopment of Social Normativity

Area of Science:

• Developmental psychology
• Social cognition
• Moral development

Background:

• Children transition from social coordination to understanding social norms.
• This shift involves treating regularities as binding standards for correction and enforcement.
• Existing paradigms lack a unified framework for this developmental transition.

Purpose of the Study:

• Propose symbolic closure as the driver of normative bindingness in early social development.
• Define and operationalize normative bindingness using a perturbation profile.
• Recast established developmental paradigms as structured tests of this framework.

Main Methods:

• Introduce symbolic closure as a stabilization operation yielding deontically binding representations.
• Define normative bindingness via scope-sensitive invariance in deontic evaluation.
• Operationalize bindingness using a perturbation profile and the Normative Closure Index (NCI).

Main Results:

• The framework recasts existing developmental paradigms as tests of perturbation profiles.
• Predicts domain-by-perturbation dissociations reflecting the moral-conventional distinction.
• Identifies a developmental pattern of increasing stability and preserved boundary sensitivity.

Conclusions:

• Symbolic closure offers a minimal perturbation grammar for understanding the emergence of 'ought' from 'is'.
• This framework explains how social regularities become binding norms.
• The model is compatible with diverse learning routes in social development.
