Assertion (A) : Gf and Gc correlate positively with each other across the age levels but with moderate magnitude.
Reason (R) : Gf and Gc have different growth patterns. Gc grows rapidly in childhood and adolescence whereas Gf grows rapidly during adulthood.
Codes :
This analysis examines the validity of Assertion (A) and Reason (R) concerning fluid intelligence (Gf) and crystallized intelligence (Gc).
Assertion (A) states a positive, moderate correlation between Gf and Gc across ages. This statement is accurate. Research shows that while Gf (reasoning ability) and Gc (knowledge base) are distinct, they tend to be positively related, indicating some level of interdependence.
Therefore, Assertion (A) is true.
Reason (R) claims Gc grows fast in childhood/adolescence, and Gf grows fast in adulthood. This statement is incorrect regarding Gf's developmental trajectory:
Because the description of Gf's growth pattern is inaccurate, Reason (R) is false.
With Assertion (A) being true and Reason (R) being false, the correct option reflects this finding.
