π§ Quick Study Guide: Fluid & Crystallized Intelligence
- π§ Fluid Intelligence (Gf): This is your ability to reason, think abstractly, and solve novel problems. It's about processing new information and adapting to new situations, independent of learned knowledge. Think "raw processing power."
- 𧩠Key Characteristics of Gf: Involves pattern recognition, abstract reasoning, and problem-solving in new contexts. It's often associated with working memory and processing speed.
- π Age Trend for Gf: Typically peaks in young adulthood (late 20s-early 30s) and then gradually declines with age.
- π Crystallized Intelligence (Gc): This refers to the accumulation of knowledge, facts, and skills acquired throughout your life. It's what you've learned and stored, like vocabulary, general knowledge, and arithmetic facts. Think "accumulated wisdom."
- π Key Characteristics of Gc: Relies on long-term memory and prior learning. It includes verbal comprehension, general information, and numerical abilities based on learned procedures.
- π Age Trend for Gc: Tends to increase throughout adulthood and may even remain stable or continue to grow into old age, as long as learning opportunities continue.
- βοΈ Relationship: While distinct, Gf can influence Gc. Strong fluid intelligence helps in acquiring new knowledge, which then becomes part of crystallized intelligence.
- π§βπ¬ Pioneers: The concepts were first introduced by Raymond Cattell and later expanded by John Horn.
