Animal Metacognition: Problems and Prospects

Researchers have begun to evaluate whether nonhuman animals share humans’ capacity for metacognitive monitoring and self-regulation. Using perception, memory, numerical, and foraging paradigms, they have tested apes, capuchins, a dolphin, macaques, pigeons, and rats. However, recent theoretical and formal-modeling work has confirmed that some paradigms allow the criticism that low-level associa...

Animal metacognition: a tale of two comparative psychologies.

A growing literature considers whether animals have capacities that are akin to human metacognition (i.e., humans' capacity to monitor their states of uncertainty and knowing). Comparative psychologists have approached this question by testing a dolphin, pigeons, rats, monkeys, and apes using perception, memory, and food-concealment paradigms. As part of this consideration, some associative mod...

The highs and lows of theoretical interpretation in animal-metacognition research.

Humans feel uncertain. They know when they do not know. These feelings and the responses to them ground the research literature on metacognition. It is a natural question whether animals share this cognitive capacity, and thus animal metacognition has become an influential research area within comparative psychology. Researchers have explored this question by testing many species using percepti...

Beyond Stimulus Cues and Reinforcement Signals

Some metacognition paradigms for nonhuman animals encourage the alternative explanation that animals avoid difficult trials based only on reinforcement history and stimulus aversion. To explore this possibility, we placed humans and monkeys in successive uncertainty-monitoring tasks that were qualitatively different, eliminating many associative cues that might support transfer across tasks. In...
