Discontinuity in development refers to:

Discontinuity in development describes the idea that human growth and development occur in distinct stages, where each stage represents a different level of functioning or understanding, leading to significant changes in behavior and abilities. This concept emphasizes that development is not a gradual and uniform process but rather consists of abrupt shifts in capability or perspective.

For example, a child may gain entirely new cognitive abilities or social skills at certain critical junctures, indicating a transition from one developmental phase to another. These stages can vary significantly from one another, impacting how individuals think, feel, and interact with the world around them.

This concept contrasts with cumulative growth patterns, which suggest that development is a continuous and smooth process, or with the idea of consistent development across the lifespan, which implies predictability and linear advancement without major shifts. Overall, recognizing these discontinuities helps educators and caregivers foster a supportive environment that accommodates and cultivates the unique changes that can occur during various developmental stages.
