Crash Course: The Growth of Knowledge
How does our knowledge grow? It turns out there are some different ideas about that. Schemas, Four-Stage Theory of Cognitive Development, and Vygotsky's Theory of Scaffolding all play different roles but the basic idea is that children think about things very differently than adults. Hank explains in today's episode of Crash Course Psychology.

Extensive biological and developmental research shows significant neglect—the ongoing disruption or significant absence of caregiver responsiveness—can cause more lasting harm to a young child's development than overt physical abuse, including subsequent cognitive delays, impairments in executive functioning, and disruptions of the body's stress response. This edition of the InBrief series explains why significant deprivation is so harmful in the earliest years of life and why effective interventions are likely to pay significant dividends in better long-term outcomes in learning, health, and parenting of the next generation.

This 6-minute video provides an overview of The Science of Neglect: The Persistent Absence of Responsive Care Disrupts the Developing Brain, a Working Paper from the National Scientific Council on the Developing Child.
