Nonhuman Intelligence: Problem-Solving, Behavioral Flexibility, and Cross- and Within-Species Comparisons

To the point

Animal intelligence means solving problems and adapting flexibly through inhibition and innovation, and it covers differences between species and differences among individuals, the challenge of fair cross‑species comparisons, links between brain size, ecology, and life history to thinking skills seen in carnivores and primates, methodological measurement challenges, and the idea that nonhuman minds sit at the crossroads of cognitive psychology, comparative cognition, and evolutionary biology with ongoing debate on how best to compare minds across species and individuals.

Nonhuman Intelligence

Animal intelligence is defined by problem-solving ability and behavioral flexibility, guiding two main lines of inquiry—cross-species comparisons about whether some taxa are truly more intelligent and whether common tasks yield fair judgments, and within-species variation tied to brain size, ecology, and life history—supported by studies on brain size and problem-solving in carnivores and on learning, memory, and self-control in primates and other mammals, while methodological challenges in motivation, social cognition, and test design complicate measurement, leaving nonhuman intelligence at the intersection of cognitive psychology, comparative cognition, and evolutionary biology with ongoing uncertainty about how best to compare minds across species and individuals.
