Animal Cognition

It has been argued that if an animal is psychologically like us, there may be more scientific reason to experiment upon it, but less moral justification to do so. Some scientists deny the existence of this dilemma, claiming that although there are scientifically valuable similarities between humans and animals that make experimentation worthwhile, humans are at the same time unique and fundamentally different. This latter response is, ironically, typical of pre-Darwinian beliefs in the relationship between human and non-human animals. Another (...) irony is that debate about such issues has facilitated the participation once more of philosophers in questions concerning experimental psychology: ironic because laboratory-oriented psychologists, especially since the turn of the last century, had been eager to establish the independence of their subject from any influence of philosophy and its investigative methods, as well as from any kind of anthropomorphism.In Britain, certainly more so than in the United States, ethical constraints have prevented the development of psychological research with animals along certain routes. By the 1980s British professional and academic societies had published codes of conduct and guidelines for their members, in part responding to public concern about the welfare of animals in the psychological laboratory. What led to the establishment of these codes and guidelines? This paper analyses the historical background against which professional concern for ethical cost in experimental animal psychology began to take shape, leading to the societies' open pronouncements of the 1980s.

Maladapting Minds discusses a number of reasons why philosophers of psychiatry should take an interest in evolutionary explanations of mental disorders and, more generally, in evolutionary thinking. First of all, there is the nascent field of evolutionary psychiatry. Unlike other psychiatrists, evolutionary psychiatrists engage with ultimate, rather than proximate, questions about mental illnesses. Being a young and youthful new discipline, evolutionary psychiatry allows for a nice case study in the philosophy of science. Secondly, philosophers of psychiatry have engaged with evolutionary (...) theory because evolutionary considerations are often said to play a role in defining the concept of mental disorder. The basic question here is: Can the concept of mental disorder be given an objective definition, or is it rather a normative concept? Thirdly and finally, evolutionary thinking in psychiatry has often been a source of inspiration for a philosophical view on human nature. Thus evolutionary psychiatrists have suggested, for example, that man's vulnerability to mental disorders may well be one of the defining features of our species. -/- Written by leading authors in philosophy, psychiatry, biology and psychology, this volume illustrates that many debates in contemporary philosophy of psychiatry are profoundly influenced by evolutionary approaches to mental disorders. Conversely, it also reveals how philosophers can help contribute to the burgeoning field of evolutionary psychiatry. It is important reading for a wide range of readers interested in mental health care and philosophy. (shrink)

ANTHROPOMORPHISM is an inveterate tendency to project human qualities into natural phenomena—consciously or not. The standard and most important variant of anthropomorphism is animism which sees a soul in everything in nature. Before entering into the role of anthropomorphism in the history of science, let us consider a few important and usually neglected logical aspects of the idea.

Seven chimpanzees in twenty-seven experiments run over the course of five years at his University of Louisiana laboratory in New Iberia, Louisiana, are at the heart of Daniel Povinelli’s case that chimpanzee thinking about the physical world is not at all like that of humans. Chimps, according to Povinelli and his coauthors James Reaux, Laura Theall, and Steve Giambrone, are phenomenally quick at learning to associate visible features of tools with specific uses of those tools, but they appear to lack (...) cognitive access to forces and other invisible causal features of those tools. Povinelli’s chimps appar- ently rely on a trial-and-error strategy to learn whether a particular tool is suitable for a particular task, and and having mastered one task they appear unable to generalize to other tasks on the basis of tool properties that are not directly visible. Thus, for instance, Povinelli’s research subjects did not immediately recognize that a tool that had been demonstrated to be non- rigid would be unsuitable for dragging a piece of food towards them. When presented with a choice between a rigid, T-shaped “rake” that they had used many times previously and a rake with non-rigid arms, Povinelli and Reaux found, over the course of eight trials, that their chimps chose the non-rigid rake as frequently as they chose the rigid one (experiment 9, chapter 7).

Millikan's account of concepts is applicable to questions about concepts in nonhuman animals. I raise three questions in this context: (1) Does classical conditioning entail the possession of simple concepts? (2) Are movement property concepts more basic than substance concepts? (3) What is the empirical content of claiming that concept meanings do not necessarily change as dispositions change?

On Anthropomorphism concerns itself with performances and artworks that explore the complex of interesting and mutually contradictory ideas located under the umbrella term, ‘anthropomorphism’. On the one hand, it is used to refer to something that resembles a human, and on the other hand it refers to our natural tendency to read human characteristics in the non-human object or animal. Moreover, an interrogation of the concept of anthropomorphism, especially as it is found in contemporary performance, suggests that there is not (...) a singular line dividing the human from the non-human but a vast terrain that houses the comical, the uncanny and the abject. The aim of this issue is to elucidate anthropomorphism in its multitude of aspects, thereby shedding light on discourses around object theatre and ecological performance that attempt to understand the more-than-human world in a way that goes beyond ‘mere’ anthropomorphism.

Anthropocentric biases manifest themselves in two different ways in research on animal cognition. Some researchers claim that only humans have the capacity for reasoning, beliefs, and interests; and others attribute mental concepts to nonhuman animals on the basis of behavioral evidence, and they conceive of animal cognition in more or less human terms. Both approaches overlook the fact that language-use deeply informs mental states, such that comparing human mental states to the mental states of nonlinguistic animals is misguided. In order (...) to avoid both pitfalls -- assuming that animals have mental lives just like we do, or assuming that they have no mental lives at all -- I argue for a functional methodological approach. Researchers should study animal cognition by identifying environmental inputs, the functional role of internal states, and behavioral outputs. Doing so will allow for cross-species comparisons in a way that the use of folk psychological terms does not. (shrink)

The representations formed by the ventral and dorsal streams of a prelinguistic agent will tend to be too qualitatively similar to support the distinct roles required by PREDICATE(x) structure. We suggest that the attachment of qualities to objects is not a product of the combination of these separate processing streams, but is instead a part of the processing required in each. In addition, we suggest that the formation of objective predicates is inextricably bound up with the emergence of language itself, (...) and so cannot be cleanly identified with any prelinguistic cognitive capacities.

I respond to an argument presented by Daniel Povinelli and Jennifer Vonk that the current generation of experiments on chimpanzee theory of mind cannot decide whether chimpanzees have the ability to reason about mental states. I argue that Povinelli and Vonk’s proposed experiment is subject to their own criticisms and that there should be a more radical shift away from experiments that ask subjects to predict behavior. Further, I argue that Povinelli and Vonk’s theoretical commitments should lead them to accept (...) this new approach, and that experiments which offer subjects the opportunity to look for explanations for anomalous behavior should be explored.

We examine the claim that the methodology of psychology leads to a bias in animal cognition research against attributing “anthropomorphic” properties to animals . This charge is examined in light of a debate on the role of folk psychology between primatologists who emphasize similarities between humans and other apes, and those who emphasize differences. We argue that while in practice there is sometimes bias, either in the formulation of the null hypothesis or in the preference of Type-II errors over Type-I (...) errors, the bias is not the result of proper use of the Neyman and Pearson hypothesis testing method. Psychologists’ preference for false negatives over false positives cannot justify a preference for avoiding anthropomorphic errors over anthropectic errors. (shrink)

Through a critical engagement with Merleau-Ponty’s discussion of the concepts of nature, life, and behavior, and with contemporary accounts of animal groups, this article argues that animal groups exhibit sociality and that sociality is a fundamental ontological condition. I situate my account in relation to the superorganism and selfish individual accounts of animal groups in recent biology and zoology. I argue that both accounts are inadequate. I propose an alternative account of animal groups and animal sociality through a Merleau-Pontian inspired (...) definition of behavior. I criticize Merleau-Ponty’s individualistic prejudice, but show that his philosophy contains the resources necessary to overcome this bias. I define behavior as a holistic, ongoing, meaningful and Umwelt-oriented intrinsically configured expression of living forms of existence. By looking at cases of animal groups drawn from contemporary studies in zoology and behavioral ecology, I show that animal groups, in the fact that they behave, manifest themselves to be a fundamental form of existence, namely, the social form of existence.

The intriguing observation that left-cerebral dominance for vocalization is ancient, occurring in frogs, birds, and mammals, grounds Corballis's argument that the predominance of right-handedness may result from an association between manual gestures and vocalization in the evolution of language. This commentary supports the general thesis that language evolved “From hand to mouth” (Corballis 2002), while offering alternatives for some of Corballis's supporting arguments.

The question, “Does the chimpanzee have a theory of mind?” is logically identical to the question, “Does the chimpanzee have a soul?” It is a peculiarity of our culture that we talk about anyone having a mind, and such talk is unhelpful for a science of behavior. The label “killjoy hypothesis” is an ad hominem attack.

This book brings together disparate strands of ToM research, lays out historical roots of the idea, and indicates better alternatives.

In this essay I consider various aspects of the rapidly growing field of cognitive ethology, concentrating mainly on evolutionary and comparative discussion of the notion of intentionality. I am not concerned with consciousness, per se, for a concentration on consciousness deflects attention from other, and in many cases more interesting, problems in the study of animal cognition. I consider how, when, where, and (attempt to discuss) why individuals from different taxa exchange social information concerning their beliefs, desires, and goals. My (...) main examples come from studies of social play in mammals and antipredator behavior in birds. Basically, I argue that although not all individuals always display behavior patterns that are best explained by appeals to intentionality, it is misleading to argue that such explanations have no place in the study of animal cognition.

What is the relation between philosophical theorizing and experimental data? A modest set of naturalistic assumptions leads to what I term the force-field puzzle. The assumption that philosophy is continuous with natural science, as captured in Quine’s force-field metaphor, seems to push us simultaneously towards thinking that there have to be conceptual constraints upon how we interpret experimental data and towards thinking that there cannot be such conceptual constraints, because all theorizing must be accountable to data and observation. The key (...) to resolving the force-field puzzle is to take a more nuanced view of how conceptual constraints can be accountable to data and observation. This can be done by developing conceptual arguments in conjunction with interpretative frameworks for making sense of experimental evidence. This paper shows how attending to important differences between different types of mindreading yields tools for interpreting experimental and observational data in a manner consistent with a (conceptually derived) constraint that I have developed elsewhere. This is the first-order constraint that second-order thinking, or thinking about thinking, is only available to language-using creatures. (shrink)

ven a cursory look at the extensive literature on mindreading in nonhuman animals reveals considerable variation both in what mindreading abilities are taken to be, and in what is taken as evidence for them. Claims that seem to contradict each other are often not inconsistent with each other when examined more closely. And sometimes theorists who seem to be on the same side are actually talking at cross-purposes. The first aim of this paper is to tackle some important framework questions (...) about how exactly the mindreading hypothesis is to be stated. It emerges in sections 1 and 2 that there are three importantly different versions of the mindreading hypothesis that need to be distinguished. The first (which I call minimal mindreading) occurs when a creature’s behavior covaries with the psychological states of other participants in social exchanges. The presence of minimal mindreading is not in itself evidence for the presence of what I term substantive mindreading. Substantive mindreading involves attributions of mental states. There are different levels of substantive mindreading, varying according to the category of mental state attributions that they involve. Section 2 explores different types of substantive mindreading, according to the extent to which they involve explicitly representing the agent’s backgtround psychological profile. This gives us a principled way of distinguishing propositional attitude mindreading from perceptual mindreading. -/- It is clear that much of the reasoning behind attributions of mindreading abilities to nonlinguistic creatures is analogical in nature. We see in section 3 that much of the discussion in this area proceeds on the basis of a double analogy between animal cognition and human cognition. Researchers assume both that animals solve many problems of social coordination that are analogous to problem solved by humans and that since humans solve those problems using mindreading strategies, so too do non-human animals. How we apply the second analogy, of course, depends upon our interpretation of the particular mindreading strategies that humans employ – in particular, it depends upon the centrality of propositional attitude psychology (or folk psychology) in human social understanding and social coordination. There are good reasons for thinking that the role of propositional attitude psychology in human social life is very much over-stated. This has repercussions for how we think about substantive mindreading in nonhuman animals. It very much weakens the analogical case for identifying propositional attitude mindreading in nonlinguistic creatures. -/- Suspicion of claims of propositional attitude mindreading in non-human animals turns out to be well-founded. In section 4 I present a revised version of an argument I have given elsewhere (Bermúdez 2003) to show that the most sophisticated form of substantive mindreading (the type of mindreading that exploits the concepts of propositional attitude psychology) is only available to language-using creatures.
