Only two of the many experiments described by Smith et al., as indicating metacognitive ability in nonhuman animals, involved metacognition as understood in the human literature. Of these, one gave negative results. In the other, one of two rhesus monkeys provided data suggesting that he might have metacognitive ability. The conjecture that any nonhuman animals have metacognitive ability is, therefore, tenuous.

Metacognition is often defined as thinking about thinking. It is exemplified in all the activities through which one tries to predict and evaluate one’s own mental dispositions, states and properties for their cognitive adequacy. This article discusses the view that metacognition has metarepresentational structure. Properties such as causal contiguity, epistemic transparency and procedural reflexivity are present in metacognition but missing in metarepresentation, while open-ended recursivity and inferential promiscuity only occur in metarepresentation. It is concluded that, although metarepresentations can redescribe metacognitive contents, metacognition and metarepresentation are functionally distinct.

Smith et al. demonstrate the viability of animal metacognition research. We commend their effort and suggest three avenues of research. The first concerns whether animals are explicitly aware of their metacognitive processes. The second asks whether animals have metaknowledge of their own uncertain responses. The third issue concerns the monitoring/control distinction. We suggest some ways in which these issues elucidate metacognitive processes in nonhuman animals.

Smith et al. present a model that they suggest may clarify aspects of the phylogenetic distribution of metacognition, based on observation of what they call uncertainty monitoring. Although they suggest that their model is supported by data collected using monkeys and dolphins, their interpretation that nonhuman animal behaviors parallel thought processes in humans may be unwarranted. The model presented by Smith et al. is inconsistent with current theories and empirical findings on the comparative aspects of metacognition. We present three oversights of the model and extend our critique to include a brief discussion of animal self-awareness, as well as current neuropsychological perspectives on metacognitive processing in humans.

This essay argues that humans have not fully understood the cognitive and affective capacities of dolphins, and that we have mistakenly defended as morally acceptable practices that actually harm dolphins. In particular, this essay argues that the current use of hundreds of captive dolphins by Sea World and similar facilities in the entertainment industry is ethically indefensible. Focusing primarily on critical differences between humans and dolphins, this essay argues that central concepts like “intelligence” and “language” (which have played a critical role in discussions about whether dolphins have moral standing) should be seen as species-specific, not universal notions. As a result, there are insufficient grounds to make the traditional claim that dolphins’ cognitive capacities place them on a significantly lower spot in the moral hierarchy than humans. This paper also claims that the full development of dolphin personalities may depend on the richness of social interaction that is common in the life of a dolphin in the wild. Consequently, dolphins can probably experience a greater degree of emotional pain or deprivation in captivity than has traditionally been thought.

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.

The existence of nonhuman persons would fly in the face of everything our species has believed about its uniqueness for thousands of years. If an “animal” like a dolphin actually has all of the traits of a “person”, that would call for as fundamental, dramatic and unsettling a shift in how we see ourselves as abandoning a geocentric view of the heavens did. In the same way that Earth no longer occupied the centre of the universe, neither would humans. It would also call for a shift in how humans treat dolphins – and, very likely, many other nonhumans.

The places where humans meet other animals matter. This is especially true when considering encounters with animals in captivity. Myriad factors come into play in these instances, not the least of which involve the physical structures of each place and the kinds of organized activities that are offered, encouraged or discouraged there. Motivated by a strong desire to get up close to a dolphin, many people seek out tourism activities offering opportunities to "swim with dolphins." But what is the nature of these swim-with-dolphin programs and how are they actually experienced by participants? If people are seeking genuine, spontaneous contact with a dolphin, does the place and activity of encounter make a ..

Metacognitive knowledge of one's own cognitive states is not as useful as is often thought. Differences between cognitive states often come down to differences in their intentional contents. For that reason, differences in behaviour are often explained by differences just in contents of first-order states. Uncertainty need not be a metacognitive condition. First-order interpretations of the target experiments are available.
