Knowledge of one's own states of mind is one of the varieties of self-knowledge. Do any nonhuman animals have the capacity for this variety of self-knowledge? The question is open to empirical inquiry, which is most often conducted with primate subjects. Research with a bottlenose dolphin gives some evidence for the capacity in a nonprimate taxon. I describe the research and evaluate the metacognitive interpretation of the dolphin's behaviour. The research exhibits some of the difficulties attached to the task of (...) eliciting behaviour that both attracts a higher-order interpretation while also resisting deflationary, lower-order interpretations. Lloyd Morgan's Canon, which prohibits inflationary interpretations of animal behaviour, has influenced many animal psychologists. There is one defensible version of the Canon, the version that warns specifically against unnecessary intentional ascent. The Canon on this interpretation seems at first to tell against a metacognitive interpretation of the data collected in the dolphin study. However, the model of metacognition that is in play in the dolphin studies is a functional model, one that does not implicate intentional ascent. I explore some interpretations of the dolphin's behaviour as metacognitive, in this sense. While this species of metacognitive interpretation breaks the connection with the more familiar theory of mind research using animal subjects, the interpretation also points in an interesting way towards issues concerning consciousness in dolphins.

This paper examines the recent literature on meta-cognitive processes in non-human animals, arguing that in each case the data admit of a simpler, purely first-order, explanation. The topics discussed include the alleged monitoring of states of certainty and uncertainty, the capacity to know whether or not one has perceived something, and the capacity to know whether or not the information needed to solve some problem is stored in memory. The first-order explanations advanced all assume that beliefs and desires come in (...) various different _strengths_, or _degrees_. (shrink)

Research on mirror self-recognition where animals are observed for mirror-guided self-directed behaviour has predominated the empirical approach to self-awareness in nonhuman primates. The ability to direct behaviour to previously unseen parts of the body such as the inside of the mouth, or grooming the eye by aid of mirrors has been interpreted as recognition of self and evidence of a self-concept. Three decades of research has revealed that contrary to monkeys, most great apes (humans, common chimpanzees, pygmy chimpanzees and orangutans (...) but not the gorilla) have convincingly displayed the capacity to recognize self by mirrors. The putative discontinuity in phylogeny of the ability suggests the existence of a so-called cognitive gap between great apes and the rest of the animal kingdom. However, methodological and theoretical inconsistencies regarding the empirical approach prevail. For instance, the observation of self-directed behaviour might not be as straightforward as it seems. In addition, the interpretation of mirror self-recognition as an index of self-awareness is challenged by alternative explanations, raising doubt about some assumptions behind mirror self-recognition. To evaluate the significance of the test in discussions of the concept of self this paper presents and analyses some major arguments raised on the mirror task. (shrink)

Researchers have begun to explore animals' capacities for uncertainty monitoring and metacognition. This exploration could extend the study of animal self-awareness and establish the relationship of self-awareness to other-awareness. It could sharpen descriptions of metacognition in the human literature and suggest the earliest roots of metacognition in human development. We summarize research on uncertainty monitoring by humans, monkeys, and a dolphin within perceptual and metamemory tasks. We extend phylogenetically the search for metacognitive capacities by considering studies that have tested less (...) cognitively sophisticated species. By using the same uncertainty-monitoring paradigms across species, it should be possible to map the phylogenetic distribution of metacognition and illuminate the emergence of mind. We provide a unifying formal description of animals' performances and examine the optimality of their decisional strategies. Finally, we interpret animals' and humans' nearly identical performances psychologically. Low-level, stimulus-based accounts cannot explain the phenomena. The results suggest granting animals a higher-level decision-making process that involves criterion setting using controlled cognitive processes. This conclusion raises the difficult question of animal consciousness. The results show that animals have functional features of or parallels to human conscious cognition. Remaining questions are whether animals also have the phenomenal features that are the feeling/knowing states of human conscious cognition, and whether the present paradigms can be extended to demonstrate that they do. Thus, the comparative study of metacognition potentially grounds the systematic study of animal consciousness.
