Fluid intelligence is the ability to solve novel reasoning problems and is correlated with a number of important skills such as comprehension, problem-solving, and learning. [4] Crystallized intelligence, on the other hand, involves the ability to deduce secondary relational abstractions by applying previously learned primary relational ...
The broad cognitive abilities (stratum II) include fluid reasoning (or Gf, forming and recognizing logical relationships among patterns, inferencing, and transforming novel stimuli) and comprehension-knowledge (or Gc, using language and acquired knowledge).
