The structure of ape (hominoidea) intelligence Kaufman-2019
We reanalyzed Primate Cognition Test Battery data using modern intelligence theory and confirmatory factor analysis. Our main goals were to interpret the stability of the Primate Cognition Test Battery tasks and factors over time and to determine if the cognitive factors that emerge from confirmatory factor analysis for apes can be interpreted using a major theory of human intelligence, the Cattell-Horn-Carroll model. We compared ape and 2-year-old child cognitive variables by analyzing Wechsler's preschool exam data. Multiple cognitive capacities provide the optimal factor solutions for apes and children, and Cattell-Horn-Carroll theory can be used to analyze ape factors. (PsycINFO Database Record (c) 2019 APA)
