Intelligence has been long-studied in humans, and across numerous disciplines. It has also been observed in the cognition of non-human animals. [5] Some researchers have suggested that plants exhibit forms of intelligence, though this remains controversial. [6] [7] [8] Intelligence in computers or other machines is called artificial intelligence.
The following outline is provided as an overview of and topical guide to human intelligence: Human intelligence is, in the human species , the mental capacities to learn, understand, and reason, including the capacities to comprehend ideas, plan, solve problems, and use language to communicate.
