Describe the concept of developmental cascade with an example.

• A. Early experiences set off a chain of effects across domains over time; example: early language delay leads to later literacy difficulties
• B. A single domain change has no effect on others
• C. Development occurs independently across domains
• D. There is no chain effect

Answer: (A)

Developmental cascade describes how an early experience or skill in one area sets off a chain of influences that unfold across multiple domains over time. The idea is that changes in one domain propagate to others, shaping development in a cumulative way. For example, an early language delay can hinder vocabulary growth and the ability to decode text, making literacy acquisition slower. That literacy gap can then reduce reading practice, lower academic performance, and affect motivation and self-confidence, which in turn influence social interactions and classroom engagement. The pattern is about interlinked effects across domains that build up over time, not isolated changes in a single area.

Other options imply that changes stay confined to one domain, that development happens independently across domains, or that there’s no chain of effects. Those ideas contradict the notion of a cascade, where early experiences reverberate through multiple aspects of development.
