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. Key Words: cognition; comparative cognition; consciousness; memory monitoring; metacognition; metamemory; self-awareness; uncertainty; uncertainty monitoring. (shrink)

According to higher-order thought accounts of phenomenal consciousness it is unlikely that many non-human animals undergo phenomenally conscious experiences. Many people believe that this result would have deep and far-reaching consequences. More specifically, they believe that the absence of phenomenal consciousness from the rest of the animal kingdom must mark a radical and theoretically significant divide between ourselves and other animals, with important implications for comparative psychology. I shall argue that this belief is mistaken. Since phenomenal consciousness might be almost (...) epiphenomenal in its functioning within human cognition, its absence in animals may signify only relatively trivial differences in cognitive architecture. Our temptation to think otherwise arises partly as a side-effect of imaginative identification with animal experiences, and partly from mistaken beliefs concerning the aspects of common-sense psychology that carry the main explanatory burden, whether applied to humans or to non-human animals.

The heart of this book is the reciprocal relationship between philosophical theories of mind and empirical studies of animal cognition.

How can science teach us that animals feel no pain when our common sense observations tell us otherwise? Rollin offers a welcome insight into questions like this in The Unheeded Cry, a rare, reasonable account of the difficult and controversial issues surrounding the images of animals found in science. Widely hailed on its first appearance, the book is updated here to include recent changes in thinking and practice in this fast growing field. With anecdotes and a dose of humour, Rollin (...) pokes holes in the neutral, objective, and value-free stance of animal-using scientists in the positivist tradition. He shows how this stance leads to the denial of the existence of animal consciousness and pain, and he points out the consequences. His work will help professionals and amateurs with an interest in the moral status of animals in their attempts to penetrate the fortress of scientific ideology and practice, and to effect change.

This paper argues that it is possible for suffering to occur in the absence of phenomenal consciousness – in the absence of a certain sort of experiential subjectivity, that is. (Phenomenal consciousness is the property that some mental states possess, when it is like something to undergo them, or when they have subjective feels, or possess qualia.) So even if theories of phenomenal consciousness that would withhold such consciousness from most species of non-human animal are correct, this neednt mean that (...) those animals dont suffer, and arent appropriate objects of sympathy and concern.

First published in 1995, The Visual Brain in Action remains a seminal publication in the cognitive sciences. For this new edition, a very substantial and illustrated epilogue has been added to the book in which Milner and Goodale review the key developments that support or challenge the views that were put forward in the first edition.
