RESEARCH & EVALUATION

Evidence,

held to

a standard.

A consistent methodology for evaluating developmental products.

CEDES is CogniCurve’s evidence system for evaluating how children’s products align with developmental science. Its methodology combines a developmental ontology, an evidence review protocol, and a traceable evaluation process.

EVIDENCE SYSTEM

Methodological foundations

CogniCurve Framework v1

A methodology for organizing behavioral evidence about real-world environments.

Behavioral methodology

CEDES evidence system

A developmental ontology, evidence review protocol, and traceable evaluation process.

THE PROBLEM

Decades of developmental research. Few consistent ways to apply it to products.

Children’s products are often described as educational or developmentally appropriate. CEDES provides a structured method for examining these descriptions against developmental research, with explicit sources, evaluation criteria, and limits.

METHODS

How the system is designed to earn trust

Developmental ontology

A structured vocabulary of developmental domains and features so every product is described the same way.

Structured vocabulary

Evidence review protocol

A written, repeatable procedure for finding, screening, and summarizing relevant research.

Review procedure

Source provenance

Every rating links back to the specific evidence behind it.

Evidence traceability

Held-out benchmark

A set of products reserved for testing, kept separate from development, to check whether the system generalizes.

Testing protocol

Locked predictions

Expected results recorded before scoring, so outcomes cannot be adjusted after the fact.

Pre-specified analysis

Pre-set decision thresholds

Pre-specified criteria for what level of agreement counts as success.

METHODOLOGY

The CogniCurve Framework

The Framework organizes how our team looks at behavior: the Context around a person, the Cognition involved, the Choice they face, and the Feedback that follows. Work moves through four steps: Observe, Model, Test, Embed.

Scope note: our current research program focuses on U.S. products. Global Fieldwork & Cultural Intelligence is a separate commercial service.
