[.ca] Wild Minds: What Animals Really Think (ISBN 0805056696)

From Amazon.com:
What's that squirrel thinking as it runs across the street? Behavioral neuroscientist Marc D. Hauser asks big questions about little brains in Wild Minds: What Animals Really Think. While his subjects aren't accessible for interviews, he believes that we can gain insight into their interior lives by examining their behavior in the context of their social and physical environments. Thus, while comparing the actions of chimps, rats, honeybees, and human infants, he is careful to keep in mind that each of them has different needs that require different kinds of intelligence and emotion and ought not be judged by the same criteria. Looking at counting, mapmaking, self-understanding, deception, and other intelligent activities, Hauser shows that the birds and the bees have more on their minds than we've come to believe. Acknowledging the vast gulf of language that separates our species from all others, he still maintains that this tool is but one of many and is no better an indication of "superior" intelligence than is the bat's fantastically well-developed echolocation system. In the last chapter, Hauser looks at moral behavior and decides that animals can be "moral patients but not moral agents"--that is, their inability to attribute mental states to others keeps them blameless for their actions but their sensitivity to suffering earns them fair treatment from the rest of us. Whether or not you agree with that, you're sure to find Wild Minds a refreshing look at the thoughts of our mute cousins. --Rob Lightner

Subtitle should be how animals and human minds differ:
Hauser has written a remarkably accessible introduction to comparative psychology. While containing the main points one might expect in a textbook outline, he does an excellent job of presenting this information in an interesting narrative form. Hauser begins with an introductory chapter that presents his basic approach and cautions against anthropomorphisms. Chapters two through four comprise a unit that focuses on those mental capacities shared by animals and human beings. Both can identify objects and predict their movement. Both can distinguish quantity. Both can navigate through space. Perhaps it takes a course in cognitive psychology to appreciate these commonalities, but I believe that Hauser does an excellent job of presenting research results for lay consumption. His presentation of animal and human infant studies of the expectancy-violation principle is alone worth the cost of the book. The second section, chapters five through seven, focus on mental capacities which seem to be qualitatively common in animals and humans, but quantitatively distinct. Hauser presents a well-balanced account of the evidence for self-awareness, teaching, and deception among animals. The final section contains two chapters on mental capacities that appear to be almost unique to human beings - language and morality. Hauser's careful review of animal communication is amazing, as is his locus of morality in the ability to inhibit selfish tendencies to maintain social conventions. I recommend this book without reservation. No reader will regret spending time with this book. It is quite stimulating.

too much "we'll never really know":
His style is a little flat: a scientist writing for popular audience and trying really hard not to talk down. But he organizes the subject really well and clearly, with chapters on tools, numbers, spatial navegation, sense of self, language, moral reasoning. Each one synthesizes a large amount of scientific research on both animals and children, with interesting anecdotes. The preface makes it clear he's writing against sentimental popular books on the subject that treat animal as being like humans inside, and themselves attack "the scientists." But this book gives a dreary image of the scientists. Each chapter describes some amazing abilities of different animals, describes some exhausting, repetitive experiments to document (it often seems) a small part of what was already suspected, and then concludes that as to the most important part -- "what animals really think" -- science doesn't know. But (drearily), they probably aren't conscious. He should be clearer than he is in summarizing what the experiments have shown, and in particular about the differences in cognitive performance (not "real thought") btw adult and infant humans, primates (his main interest), birds (who get less attention), rats (still less), and social insects (who make a few star turns).

What Do Animals Really Think? You Won't Find it in this Book:
As another reader has pointed out, Hauser's subtitle is misleading. He readily admits that scientific studies on the nonhuman animal mind are very incomplete, but based on the limited evidence to this point, rather rashly concludes that they are not on a par with human animal minds (according to him, nonhuman animals are not self-aware and do not feel embarrassment or shame, but like humans three years old or younger, deserve good treatment from us.) In other words, he comes across, like the more enlightened scientists, as a welfarist--treat 'em right, but keep 'em in their place (so we can keep experimenting on them). Hauser is careful not to be condescending to those who may suspect that their dogs or cats or any other animals have more between their ears than we currently understand. In the first chapter he states his case against popular writers like Jeffrey Masson and Elizabeth Marshall Thomas, whom he claims commit the "sin" of anthropomorphosis--but it's not a diatribe. If you can get past that clearly stated bias, Hauser's book is an informative if unsatisfying read, because the findings he presents ultimately leave you up in the air about what animals really think.

Useful but not very clear:
Hauser is not a good writer. His explanations are often unclear. His arguments are often disorganized. There is a lot of interesting stuff here, and it's a useful antidote to the rampant anthropomorphism of many less scientific books.

Shaping neuron nets:
Studies of human cognition inevitably raise the question: "Are other animals 'conscious'?". This immediately leads to a more perplexing question: "What is consciousness?". With the concept still but vaguely defined in human terms, asking it of the other animals evokes a host of difficulties. Hauser, to his credit, makes a worthwhile attempt to deal with both questions. In this sweeping survey, he declares that simplistic approaches to how the various primates deal with life are misplaced. There is a range of animal awareness out there, shaped by the forces of natural selection. Each species must be studied carefully and intensively, both in controlled and wild conditions. And the work, he insists, has barely started. He combines his field experience with the work of many researchers in revealing facets of consciousness. Hauser's study was stimulated by a young monkey giving him a hug. He calls these elements "mental tool kits". By this he explains that similar conditions generate similar responses in the animal. This suggests there are probably areas in the brain common across many species. When conditions change, however, the response may vary wildly, indicating dissimilarity in capacity. A startling contrast is the range of food storage sites among different species. A dog may bury a bone in the garden, but a Clark's Nutcracker can stash up to thirty thousand seeds in six thousand locations - and find most of them the following Spring. Hauser calls this ability "cognitive mapping" - a special talent derived over long evolutionary time. Other animals have the role of "space travelers", although Clark's must hold some kind of record. "Self-awareness" is an all-encompassing term. In the largest and most significant part of the book, Hauser dodges the vague, but common, phrase, replacing it with "self-recognition". This term is a more measurable aspect of cognition. Experiments with mirrors demonstrate that some primates know who they're looking at, while others see intruders or remain indifferent. Strangely, some birds seem to recognise themselves in reflected images. Expressing self-awareness means communicating. For us, that's done with speech or writing. With other creatures, other forms of expression must be inferred from observation. Deception is a commonly used test. An animal aware of itself, and aware of others as well, is likely to derive the other's intent. When another's intention can be directed, and the deceiver gains from that guiding, individuality seems enhanced. How far we can take such analyses is one of Hauser's calls for more research. Language and thought are far too closely aligned in the minds of most researchers, Hauser believes. That link restricts "real" thoughts to those that can express them in words - in short, only humans. Hauser counters that thought is something we can interpret from actions - and the greater the variance in action, the better. He looks back at our evolutionary beginnings through the eyes of today's primates. Thought, he argues was there - language was a gloss that came later. The implication is that researchers need to try fresh approaches to studying how "wild minds" can be better understood. The result is the growth of a new discipline, cognitive ethology which encompasses a wide range of species who have, or might possess, thoughts we can identify. This book is a major step in furthering that new field. \ostephen a. haines - Ottawa, Canada\c
