Schaie Cognitive Development Model

Schaie’s stages of cognitive development

▪ It examines the development of the use of the intellect in a social context.

▪ The seven stages revolve around motivational goals that appear at different stages of life.

▪ These goals:

✔ They move from the acquisition of information and skills → What do I

need to know?

✔ To the practical integration of knowledge and skills → How should I use

my knowledge?

✔ The search for meaning and purpose → Why should I know?

Schaie Cognitive Development Model

• how the way people use intelligence changes throughout life. Unlike theories that focus only on children, Schaie looked at cognitive development across adulthood and old age.

1. Acquisitive Stage

2. Stage of Achievement

3. Responsibility Stage

4. Executive Stage

5. Reorganisation Phase

6. Reintegrative Phase

7. Legacy Creation Stage

1. Acquisitive Stage

(Childhood and adolescence)

• People learn information and skills mainly for future use.

• Focus is on gaining knowledge through school, family, and experiences.

• Memory, reasoning, and problem-solving abilities are developing.

Example:
A teenager studies maths, languages, and science to prepare for adult life.

2. Stage of Achievement

(Late teens to early adulthood)

• 19/21 - 30/31.

• Individuals use what they learned to achieve goals.

• Intelligence becomes practical and directed toward success.

• Decisions about career, relationships, and education become important.

Example:
A university student applies knowledge to get qualifications and build a career.

3. Responsibility Stage

(Adulthood)

• 39 - 61 years.

• Adults use cognitive skills to manage responsibilities toward others.

• Thinking becomes focused on family, work, and community obligations.

• Problem-solving is often practical and emotionally aware.

Example:
A parent organizes finances, childcare, and work responsibilities.

4. Executive Stage

(Middle adulthood)

• Some adults take on leadership or decision-making roles.

• They coordinate complex systems involving many people.

• Requires planning, judgment, and long-term thinking.

Example:
A manager or political leader making decisions for a company or organization.

5. Reorganisation Phase

(Later adulthood / early retirement)

• After retirement or major life changes, priorities shift.

• People reorganize their lives and goals.

• Intelligence is used to adapt to new lifestyles and reduced responsibilities.

Example:
A retired person learning new hobbies or changing daily routines.

6. Reintegrative Phase

(Late adulthood)

• Older adults become more selective about where they use mental energy.

• They focus on activities that are most meaningful or important.

• Experience and wisdom become more valuable than speed of thinking.

Example:
An older adult chooses to spend time with family rather than managing many commitments.

7. Legacy Creation Stage

(Advanced old age)

• People think about what they will leave behind for future generations.

• Focus may be on sharing wisdom, traditions, memories, or achievements.

• Reflection and life review become important.

Example:
A grandparent writing memoirs or passing down family stories and values.
