More stimulating environments can increase the number of synapses in the brain which increases synaptic activity. In humans this is most likely to occur during the development of the brain but can also occur in adults. Most of the research on environmental enrichment has been carried out on non human animals.

A large body of research has explored the way attention and expectation affect the behavior of non-human animals, and much of this work suggests that attention operates in birds, mammals and reptiles in much the same way that it does in humans. [32]
Consequently, individual intelligence within the human species might be modulated by the degree of cortical convolution. [ 38 ] An analysis published in 2019 found the contours of 677 children and adolescent (mean age 12.72 years) brains had a genetic correlation of almost 1 between IQ and surface area of the supramarginal gyrus on the left ...
Crystallized intelligence (g c) includes learned procedures and knowledge. It reflects the effects of experience and acculturation. It reflects the effects of experience and acculturation. Horn notes that crystallized ability is a "precipitate out of experience," resulting from the prior application of fluid ability that has been combined with ...
To Darwin, humans and animals shared the same mental cognition to varying degrees based on their place in the evolutionary timeline. This understanding of mental continuity between animals and humans form the basis of comparative cognition.
The Cattell–Horn–Carroll theory is an integration of two previously established theoretical models of intelligence: the theory of fluid and crystallized intelligence (Gf-Gc) (Cattell, 1941; Horn 1965), and Carroll's three-stratum theory (1993), a hierarchical, three-stratum model of intelligence. Due to substantial similarities between the ...
Humans are also prone to making up facts, but are generally aware if that's the case. Another serious shortcoming of currently existing AI systems is limited memories.
Psychometric analysis of measurements of human cognitive abilities (intelligence) may suggest that there is a single underlying mechanism that impacts how humans learn. In the early 20th century, Charles Spearman noticed that children's scores on different measures of cognitive abilities were positively correlated. Spearman believed that these ...
