The correct answer is False
K. Warner Schaie proposed a complete model of stages of cognitive development from childhood to old age. These are seven stages of age-related cognitive development based on social roles and learning objectives:
- acquisitive stage;
- director stage;
- responsible internship;
- executive internship;
- reorganization stage;
- reintegrative stage;
- inheritance creation stage.
This model suggests the need to develop new types of intelligence tests that have ecological validity for adults.
