We develop a formal semantic analysis of the alarm calls used by Campbell’s monkeys in the Tai forest and on Tiwai island —two sites that differ in the main predators that the monkeys are exposed to. Building on data discussed in Ouattara et al. :e7808, 2009a; PNAS 106: 22026–22031, 2009b and Arnold et al., we argue that on both sites alarm calls include the roots krak and hok, which can optionally be affixed with -oo, a kind of attenuating suffix; in (...) addition, sentences can start with boom boom, which indicates that the context is not one of predation. In line with Arnold et al., we show that the meaning of the roots is not quite the same in Tai and on Tiwai: krak often functions as a leopard alarm call in Tai, but as a general alarm call on Tiwai. We develop models based on a compositional semantics in which concatenation is interpreted as conjunction, roots have lexical meanings, -oo is an attenuating suffix, and an all-purpose alarm parameter is raised with each individual call. The first model accounts for the difference between Tai and Tiwai by way of different lexical entries for krak. The second model gives the same underspecified entry to krak in both locations, but it makes use of a competition mechanism akin to scalar implicatures. In Tai, strengthening yields a meaning equivalent to non-aerial dangerous predator and turns out to single out leopards. On Tiwai, strengthening yields a nearly contradictory meaning due to the absence of ground predators, and only the unstrengthened meaning is used. (shrink)

Recent work in judgment and decision-making has shown that a good’s price can have irrational effects on people’s preferences. People tend to prefer goods that cost more money and assume that such expensive goods will be more effective, even in cases where the price of the good is itself arbitrary. Although much work has documented the existence of these pricing effects, unfortunately little work has addressed where these price effects come from in the first place. Here we use a comparative (...) approach to distinguish between different accounts of this bias and to explore the origins of these effects. Specifically, we test whether brown capuchin monkeys (Cebus apella) are also susceptible to pricing effects within the context of an experimentally trained token economy. Using a capuchin population previously trained in a token market, we explored whether monkeys used price as an indicator of value across four experiments. Although monkeys demonstrated an understanding of which goods had which prices (consistently shifting preferences to cheaper goods when prices were increased), we observed no evidence that such price information affected their valuation of different kinds of goods. These results suggest that human price effects may involve more sophisticated human-unique cognitive capacities, such as an understanding of market forces and signaling. (shrink)

The article analyzes the neural and functional grounding of language skills as well as their emergence in hominid evolution, hypothesizing stages leading from abilities known to exist in monkeys and apes and presumed to exist in our hominid ancestors right through to modern spoken and signed languages. The starting point is the observation that both premotor area F5 in monkeys and Broca's area in humans contain a “mirror system” active for both execution and observation of manual actions, and that F5 (...) and Broca's area are homologous brain regions. This grounded the mirror system hypothesis of Rizzolatti and Arbib (1998) which offers the mirror system for grasping as a key neural “missing link” between the abilities of our nonhuman ancestors of 20 million years ago and modern human language, with manual gestures rather than a system for vocal communication providing the initial seed for this evolutionary process. The present article, however, goes “beyond the mirror” to offer hypotheses on evolutionary changes within and outside the mirror systems which may have occurred to equip Homo sapiens with a language-ready brain. Crucial to the early stages of this progression is the mirror system for grasping and its extension to permit imitation. Imitation is seen as evolving via a so-called simple system such as that found in chimpanzees (which allows imitation of complex “object-oriented” sequences but only as the result of extensive practice) to a so-called complex system found in humans (which allows rapid imitation even of complex sequences, under appropriate conditions) which supports pantomime. This is hypothesized to have provided the substrate for the development of protosign, a combinatorially open repertoire of manual gestures, which then provides the scaffolding for the emergence of protospeech (which thus owes little to nonhuman vocalizations), with protosign and protospeech then developing in an expanding spiral. It is argued that these stages involve biological evolution of both brain and body. By contrast, it is argued that the progression from protosign and protospeech to languages with full-blown syntax and compositional semantics was a historical phenomenon in the development of Homo sapiens, involving few if any further biological changes. Key Words: gestures; hominids; language evolution; mirror system; neurolinguistics; primates; protolanguage; sign language; speech; vocalization. (shrink)

Thinkers in related fields such as philosophy, psychology, and education define metacognition in a variety of different ways. Based on an emerging standard definition in psychology, we present evidence for metacognition in animals, and argue that mindreading and metacognition are largely orthogonal.

In Japan, yaen kōen or "wild monkey parks" are popular visitor attractions that show free-ranging monkey troops to the paying public. Unlike zoos, which display nonhuman animals through confinement, monkey parks control the movements of the monkeys through provisioning. The parks project an image of themselves as "natural zoos," claiming to practice a more authentic form of displaying animals-in-the-wild than that practiced by the zoo. This article critically evaluates the monkey park's claim by examining park management (...) of the monkeys. The article shows the monkey park's claim to display wild monkeys to be questionable because of the way that provisioning changes monkey behavior. Against the background of human encroachment onto the forest habitat of the monkey, the long-term effect of provisioning is to sedentarize nomadic monkey animals and to turn the wild monkey park into a megazoo.

This research examines how and why reactions to other consumers’ unethical behavior differ among consumers and vary in different situations. Drawing on construal level theory, the authors propose that the relationship between other consumers’ unethical behavior and focal consumers’ unethical behavior is moderated by focal consumers’ construal level, and self-expressiveness mediates this moderating effect. Specifically, consumers at higher construal levels tend to view their behavior as more self-expressive and are thus less likely to imitate other consumers’ unethical behavior. Study 1 (...) indicates that focal consumers who have a chronic tendency to construe information at high levels are less likely to replicate other consumers’ unethical behavior than those who have a chronic tendency to construe information at low levels. Studies 2, 3a and 3b show that when primed with higher-level construals, consumers are less likely to follow other consumers’ unethical behavior than when primed with lower-level construals. The mediating effect of self-expressiveness was tested and supported in Study 1 and Study 3b. These findings help to better understand consumers’ reactions to other consumers’ unethical behavior.

Virtue ethics has generated a great deal of excitement among ethicists largely because it is seen as an alternative to the traditional theories – utilitarianism and Kantian ethics – which have come under considerable scrutiny and criticism in the past 30 years. Rather than give up the enterprise of doing moral theory altogether, as some have suggested, others have opted to develop an alternative that would hopefully avoid the shortcomings of both utilitarianism and Kantian ethics. Several writers, such as Jorge (...) Garcia and Michael Slote, have tried to develop this alternative of virtue ethics, or at least sketch out ways such a theory could be developed. (shrink)

The chapter discusses the following quotation from Charles Peirce: "One of these days, perhaps, there will come a writer of opinions less humdrum than those of Dr. (Alfred Russel) Wallace, and less in awe of the learned and official world...who will argue, like a new Bernard Mandeville, that man is but a degenerate monkey, with a paranoic talent for self-satisfaction, no matter what scrapes he may get himself into, calling them 'civilization,' and who, in place of the unerring instincts (...) of other races, has an unhappy faculty for occupying himself with words and abstractions, and for going wrong in a hundred ways before he is driven, willy-nilly, into the right one. Dr. Wallace would condemn such an extravagant paradoxer." Charles Peirce, 1901 -/- . (shrink)

Pike, Gregory K Drug abuse has come into the public spotlight again as the Australia21 group recently released several documents arguing for an end to the prohibition of drugs like cannabis, heroin, cocaine, ecstasy and amphetamine. The arguments are not new, and those who advance them probably think it is only a matter of time before they achieve their goal.

Research with nonhuman primates is essential to medical progress and will still be necessary for the foreseeable future. Almost all research scientists agree that animal research is critical to understanding basic biology, discovering new treatments for human (and animal) diseases, and maximizing the safety of new medicines while minimizing their harm to humans. All but two of the Nobel prizes in medicine awarded over the last one hundred years have depended on animal research, and the list of modern medicines, vaccines, (...) and other treatments, as well as basic science discoveries, is so extensive that it could not be adequately covered in even a huge volume. Increases in average life span in the last century are the result of improved public health measures, and many diseases may be related to lifestyle choices. But animal research has contributed to understanding these factors and to the development of vaccines and lifesaving treatments. The philosophical debate regarding the benefits and moral costs of animal research has also filled many volumes by ethicists and philosophers. The major arguments against the use of animals in medical research have been explicitly refuted by a few brave scientists, as well as implicitly by the vast majority of the working biomedical science community. My contribution to this discussion is to provide a personal perspective on my decision if, when, and how to use monkeys in research experiments on Parkinson disease. As a physician researcher, I have been working for many years to understand and cure Parkinson disease. (shrink)

Monkeys and apes, inhabiting variable environments and subjected to K-selection, exhibit cultural behavior transmitted horizontally and vertically, like cetaceans. Behaviors enhancing better health and nutrition, predator avoidance, or mate selection, can affect differential reproduction.Furthermore, dominance hierarchies and social status not only affect the transmission and acceptance of new behaviors but they may also affect genetic inheritance.

Abstract. A rhesus monkey, Helen, from whom the striate cortex was almost totally removed, was studied intensively over a period of 8 years. During this time she regained an effective, though limited, degree of visually guided behaviour. The evidence suggests that while Helen suffered a permanent loss of `focal vision she retained (initially unexpressed) the capacity for `ambient vision.

An elementary exercise in symbolizing an existential to universal relation reveals expressive limitations in standard first-order predicate-quantificational logic. Alternative translations of a sample some-every sentence are considered and rejected after criticism, leaving as the best choice a particular structure that demonstrably does not serve for all predicates available to the ordinary language to which the sample sentence belongs. We explain the difficulties encountered in trying to arrive at an adequate translation of the sentence in classical logic, as background to examining (...) five alternative nonclassical logics to resolve the problem. We settle finally if only provisionally in the process on a version of intensional logic that permits reference and true predication of constitutive properties to nonexistent as well as existent objects.

Nietzsche is a popular source of inspiration for transhumanist writers. Some, such as Sorgner and More, argue that Nietzsche ought to be considered a precursor of the movement. Transhumanism is a philosophy committed to the desirability of using technology to transform human beings, through significant alteration of their brains and bodies, into a new posthuman species. One of the defining characteristics of transhumanism is the desire for personal immortality. I argue that this feature of transhumanism is wholly incompatible with Nietzsche’s (...) philosophy, and a close examination of this disagreement brings out the degree to which transhumanists and Nietzsche differ in their values and philosophical commitments. Nietzsche does not think that personal immortality is desirable or metaphysically possible. I show that his views have more in common with philosophers like Bernard Williams and Derek Parfit than they do with transhumanism. (shrink)

This essay dwells in the interstitial space between human and nonhuman species attributions to consider the dense political and theoretical activity that the domain capacitates. It begins by discussing the bifurcated funding work of the Arcus Foundation – LGBT rights and great ape conservation – as a means of examining how currently prevailing species divisions that putatively work through expansive notions of embodiment in actuality deploy the same logics present in colonial schemes of bodily division. It then relatedly considers an (...) intimate transspecies relationship between a human, Sandra Herold, and a chimpanzee, Travis, which ended tragically. The essay then puts the concepts of trans* and animacy into productive tension to explore how life and liveness become contingently associated with certain bodies through shifting processes of racial and sexual division. Building from these conceptual framings, it preliminarily introduces a new analytic tool, trans*plant, to facilitate more comprehensive analyses of how bodies move across media, and what those movements facilitate in terms of reproducing or disrupting embodiment categories that rely on naturalized understandings of bodily difference.

Readers have struggled to interpret an image from the end of Juvenal's fifth satire, a poem which focusses upon the poor hospitality shown to a dinner guest, Trebius, at the hands of his host, Virro. After repeatedly juxtaposing the luxurious food served to Virro with the scant fare served to Trebius, Juvenal describes the final course of thecena. He again contrasts the host's hyper-abundance with his guest's mere scraps (5.149–55):Virro sibi et reliquis Virronibus illa iubebitpoma dari, quorum solo pascaris odore,qualia (...) perpetuus Phaeacum autumnus habebat,credere quae possis subrepta sororibus Afris:tu scabie frueris mali, quod in aggere roditqui tegitur parma et galea, metuensque flagellidiscit ab hirsuta iaculum torquere capella.Virro will demand that he and the rest of his entourage receive these apples—though you'll dine on their smell alone—like those the endless autumn of the Phaeacians used to yield, which you could believe stolen away from the African sisters: you will enjoy the scab of an apple, which, on the Embankment, is gnawed by someone who is protected by a buckler and helm and who, fearing a whipping, learns to hurl a javelin from atop a shaggy goat.While the core contrast between the quality of each type of fare is clear, the concludingqui-clause is less intelligible. Who could this entity be? On line 153, the scholiast comments:quale simia manducat. Whilequalecould refer to the object being eaten (scabie mali quod) rather than to thequi-antecedent, it is clear in any case that the ancient reader felt that 5.153–5 evoked the image of an ape. Recent commentaries on Juvenal's fifth satire reflect a scholarly consensus: J.D. Duff, Edward Courtney, Susanna Braund and Biagio Santorelli all follow the scholiast's suggestion and believe that the passage describes a trained ape, as do recent readers of the poem. (shrink)

Stoerig and Cowey’s work is widely regarded as showing that monkeys with lesions in the primary visual cortex have blindsight. However, Mole and Kelly persuasively argue that the experimental results are compatible with an alternative hypothesis positing only a deficit in attention and perceptual working memory. I describe a revised procedure which can distinguish these hypotheses, and offer reasons for thinking that the blindsight hypothesis provides a superior explanation. The study of blindsight might contribute towards a general investigation into animal (...) consciousness, though there is a problem when it comes to showing how a non-verbal animal can indicate whether or not it is perceiving consciously. Perhaps whether there is something that it is like to be a given animal depends on whether it exhibits the cognitive profile of conscious vision as opposed to non-conscious “natural blindsight.”.

This paper presents a concept for using robots as part of a design strategy that encourages a ‘bottom-up’ approach to environmental control. Robot friendly environments within the building enclosure are proposed and an analogy is made to natural ‘ecosystems’. Detail design issues are discussed, including the relationships that might occur between robots, building users and maintenance engineers. The concept is speculative in that it presents some of the implications of a mode of actuation that is radically different from the usual.

The data reviewed in Barresi & Moore's treatment of social understanding is recast in terms of a model of social intelligence that was advanced some time ago (Gallup 1982). When it comes to their analysis of the behavior of other individuals, most primates (and humans younger than 18 months of age) appear to function as radical behaviorists, whereas chimpanzees and older infants show evidence of becoming primitive cognitive psychologists.
