The Fluid intelligence reflects information-processing capabilities, reasoning and memory. Crystallized intelligence is the accumulation of information, skills and strategies that people have learned through experience and that they can apply in problem-solving situations. Intelligence is most widely studied in humans, but has also been observed in non-human animals and in plants. Artificial intelligence is intelligence in machines.
