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 modelers have attempted to describe animals' "metacognitive" performances in low-level, associative terms-an important goal if achievable. The authors summarize the empirical and theoretical situation regarding these associative descriptions. The associative descriptions in the animal-metacognition literature fail to encompass important phenomena. The sharp focus on abstract, mathematical associative models creates serious interpretative problems. The authors compare these failed associative descriptions with an alternative theoretical approach within contemporary comparative psychology. The alternative approach has the potential to strengthen comparative psychology as an empirical science and integrate it more fully within the mainstream of experimental psychology and cognitive science.
