As its title suggests, this recently-published paper: "Information compression as a unifying principle in human learning, perception, and cognition" (PDF, Complexity, vol. 2019, Article ID 1879746, 38 pages, 2019, https://doi.org/10.1155/2019/1879746
) describes evidence for the idea that information compression is a unifying principle in human intelligence.
That principle is the foundation for the SP System, meaning the SP Theory of Intelligence and its realisation in the SP Computer Model, described in "The SP theory of intelligence: an overview" (PDF, Information, 4 (3), 283-341, 2013, bit.ly/1NOMJ6l
