Which of the following is NOT one of the five basic assumptions about growth and development?

The statement that progress orderly from complex to simple is not one of the basic assumptions about growth and development because growth and development generally follow a pattern of progression from simple to complex. For example, in cognitive development, children first learn to recognize patterns and later develop more complex reasoning skills.

Understanding growth and development involves recognizing that individuals progress in a way that is often unique to them, as indicated by the highly individualized rate of development. Each body system can also experience growth and changes at different rates depending on various factors, such as genetics and environment. The total process of growth and development encompasses these various changes across all stages and systems, reinforcing that development is integrative and multifaceted rather than a linear or solely simple-to-complex approach.
