Corballis's explanation for right-handedness in humans relies heavily on the gestural protolanguage hypothesis, which he argues for by a series of “intuition pumps.” Scrutinizing the mirror system hypothesis and modern gesture as components of the argument, we find that they do not provide the desired evidence of a gestural precursor to speech.

US livestock agriculture hasdeveloped and intensified according to a strictproductionist model that emphasizes industrialefficiency. Sustainability problems associatedwith this model have become increasinglyevident and more contested. Traditionalapproaches to promoting sustainable agriculturehave emphasized education and outreach toencourage on-farm adoption of alternativeproduction systems. Such efforts build on anunderlying assumption that farmers areempowered to make decisions regarding theorganization and management of theiroperations. However, as vertical coordinationin agriculture continues, especially in theanimal agriculture sectors, this assumptionbecomes less valid. This paper examines how thechanging industrial structure in (...) four USlivestock sectors (poultry, hogs, beef, anddairy) affects possibilities in each forpromoting more sustainable productionpractices. Comparisons between the sectors arebased on the relative ability to employ anintensive pasture or alternative (deep-bedded)housing system, which are widely seen assustainable livestock alternatives. While thehighly integrated poultry sector appearsimpregnable to traditional sustainableagriculture approaches, the cow-calf sub-sectorof the beef industry, non-feedlot dairyoperations, and small parts of the hogindustry, especially in the Midwest, stillretain some potential for effectively targetingthe farmer. Building on the presentation ofbarriers and opportunities in the fourlivestock sectors, the paper concludes byevaluating several structurally-orientedapproaches to promoting a more sustainablelivestock agriculture that should complementmore traditional approaches. They includedeveloping alternative coordinated networks inlivestock agriculture, pressing integrators topermit more sustainable production practices,and working for legislation that shifts moredecision-making within integrated systemstowards growers.

People coordinate body postures and gaze patterns during conversation. We review literature showing that (1) action embodies cognition, (2) postural coordination emerges spontaneously when two people converse, (3) gaze patterns influence postural coordination, (4) gaze coordination is a function of common ground knowledge and visual information that conversants believe they share, and (5) gaze coordination is causally related to mutual understanding. We then consider how coordination, generally, can be understood as temporarily coupled neuromuscular components that function as a collective unit (...) known as a coordinative structure in the motor control literature. We speculate that the coordination of gaze and body sway found in conversation may be understood as a cross‐person coordinative structure that embodies the goals of the joint action system. (shrink)

Despite the importance of emotions for learning and performance of future behaviors, few studies have attempted to qualitatively describe emotions that arise in response to self-control successes and failures. This study is the first qualitative analysis to examine the complexity of goals that give rise to self-control challenges of two types—initiation and inhibition—and the emotions that follow success and failure experiences. Thematic analysis revealed a sometimes blurred line between inhibition and initiation, and a variety of goals that challenge views that (...) successful self-control is good and unsuccessful self-control is bad. Descriptions of self-control challenges and resulting experiences further uncovered distinctions and apparent emotional profiles characteristic of self-control dilemmas involving inhibition or initiation, suggesting that these two forms of self-control are not only theoretically but also experientially distinct.

We investigated the coupling between a speaker's and a listener's eye movements. Some participants talked extemporaneously about a television show whose cast members they were viewing on a screen in front of them. Later, other participants listened to these monologues while viewing the same screen. Eye movements were recorded for all speakers and listeners. According to cross-recurrence analysis, a listener's eye movements most closely matched a speaker's eye movements at a delay of 2 sec. Indeed, the more closely a listener's (...) eye movements were coupled with a speaker's, the better the listener did on a comprehension test. In a second experiment, low-level visual cues were used to manipulate the listeners' eye movements, and these, in turn, influenced their latencies to comprehension questions. Just as eye movements reflect the mental state of an individual, the coupling between a speaker's and a listener's eye movements reflects the success of their communication. (shrink)

Conversation is supported by the beliefs that people have in common and the perceptual experience that they share. The visual context of a conversation has two aspects: the information that is available to each conversant, and their beliefs about what is present for each other. In our experiment, we separated these factors for the first time and examined their impact on a spontaneous conversation. We manipulated the fact that a visual scene was shared or not and the belief that a (...) visual scene was shared or not. Participants watched videos of actors talking about a controversial topic, then discussed their own views while looking at either a blank screen or the actors. Each believed (correctly or not) that their partner was either looking at a blank screen or the same images. We recorded conversants’ eye movements, quantified how they were coordinated, and analyzed their speech patterns. Gaze coordination has been shown to be causally related to the knowledge people share before a conversation, and the information they later recall. Here, we found that both the presence of the visual scene, and beliefs about its presence for another, influenced language use and gaze coordination. (shrink)

Until recently, it was assumed that co-representation of others’ actions, an essential part in joint action, is biologically tuned. However, research demonstrated that we also simulate actions of non-biological interaction partners under certain conditions. In the present study, we investigated whether perceived intentionality or perspective taking is the underlying mechanisms of this phenomenon. Participants saw a short video fragment of a non-biological agent as main character. The movements of this agent were either described as intentional or as unintentional. Furthermore, participants (...) were instructed to either take the perspective of this non-biological agent or not. Results show that perspective taking and perceived intentionality both lead to action co-representation of non-biological actions. Possible explanations for these findings are discussed. (shrink)

The target article offers anegative, eliminativistthesis, dissolving the specialness of mirroring processes into a solution of associative mechanisms. We support the authors' project enthusiastically. What they are currently missing, we argue, is apositive, generativethesis about associative learning mechanisms and how they might give way to the complex, multimodal coordination that naturally arises in social interaction.

Although several theories of online syntactic processing assume the parallel activation of multiple syntactic representations, evidence supporting simultaneous activation has been inconclusive. Here, the continuous and non‐ballistic properties of computer mouse movements are exploited, by recording their streaming x, y coordinates to procure evidence regarding parallel versus serial processing. Participants heard structurally ambiguous sentences while viewing scenes with properties either supporting or not supporting the difficult modifier interpretation. The curvatures of the elicited trajectories revealed both an effect of visual context (...) and graded competition between simultaneously active syntactic representations. The results are discussed in the context of 3 major groups of theories within the domain of sentence processing. (shrink)

Book reviewed in this article: Ethics in Social and Behavioral Research. By Edward Diener and Rick Crandall The Ethics of Social Intervention. Gordon Bermant, Herbert C. Kelman, Donald P. Warwick.

The first thorough examination of C. Wright Mills's intellectual roots, this book also is the first to present Mills's full analysis in his unpublished as well as published writings of the work of his precursors, mentors, and critics. Mills' intellectual line of descent is traced from the American institutional economists, especially Thorstein Veblen and Clarence Ayres, and the American pragmatists, especially John Dewey and George H. Mead—an evolution influenced though not determined by ideas from Europe. Always the critic and gadfly, (...) Mills subjected all theories to his special brand of analysis and synthesis. For example, his books on U.S. social stratification are seen by Tilman as a trilogy updating Veblen with ideas from the pragmatists, spiced with a good bit of Max Weber but very little Man. Power, his other chief concern, also was subjected to his creative American eclecticism. As a lifelong seeker of knowledge, Mills studied the great European social thinkers—notably Marx, Mosca, Pareto, Michels, Weber, Mannheim, and Freud—until his untimely death. Explaining Mills's self-description as a "plain Marxist," Tilman writes that it "amounted to little more than a willingness to use Marx's values, vocabulary, and model when these seemed relevant and to ignore them when they did not." Regarding alleged affinities between Freud and Mills, Tilman argues these were "tenuous at best and, although the linkage with the neo-Freudians was stronger, Mills remained critical of Homey and Fromm because they had "not succeeded in entirely overcoming Freud's biological metaphysic." Although the American radical tradition is complex and varied, the heritage that most influenced Mills, Tilman contends, contains elements of evangelical Protestantism and of liberal pragmatism. "It was Charles Wright Mills more than any other thinker in recent years," he concludes, "who synthesized these strands of thought and then wove them into an authentic American radical theory.".

Martha Nussbaum’s new book Political Emotions is a contribution to political philosophy and, simultaneously, a moral-psychological study of the emotions. In it, she revisits some of the most prominent themes in her 2004 book Hiding from Humanity and her 2001 treatise, Upheavals of Thought. As Nussbaum points out in the opening pages of Political Emotions, one of her goals in this work is to answer a call issued by John Rawls for a “reasonable moral psychology” that would be conceptually refined (...) and empirically grounded, since a complete theoretical account of the just society must be informed by a suitably complex, accurate conception of human emotions. On the whole, Political Emotions is a remarkably successful book that combines several areas of philosophical research in which the author’s proficiency is well known. It shows how problems that lie on the more intimate side of ethics, pertaining for instance to friendship and family life, have relevance for social justice and publi .. (shrink)

This paper follows the question of violence as a guide to exploring the link between the metaphysical, social, and political in Adorno’s thought. More specifically, I argue that violence, in the form of the exclusion, domination, and fungibility of life, marks the shared space of the metaphysical, material, and ethical for Adorno. Hence, this project contests the longstanding Habermas-inspired notion that there is something unclear in the way in which Adorno’s metaphysical and methodological critiques connect to his social and political (...) concerns—most specifically, his desire to address real suffering. In addition, this paper contributes to the growing interest in Adorno’s Marxism, showing that it is through his commitments to Marx that Adorno sees the real, material importance of his critique of metaphysics and ontology, as well as the possibility for resisting the forces of social domination.Cet article suit la question de la violence comme une guide pour explorer le lien entre la métaphysique, le social et le politique dans la pensée d’Adorno. Plus particulièrement, je soutiens que la violence, sous la forme de l’exclusion, la domination et la fongibilité de la vie, marque l’espace partagé de la métaphysique, du matériel et de l’éthique chez Adorno. Dès lors, ce projet remet en cause la notion de longue date inspirée par Habermas selon laquelle il y aurait quelque manque de clarté dans la manière dont les critiques métaphysiques et méthodologiques d’Adorno se relient avec ses soucis sociaux et politiques—plus spécifiquement son désir de s’occuper de la souffrance réelle. Par ailleurs, cette étude contribue à l’intérêt en plein essor au marxisme d’Adorno, montrant que c’est dans ses engagements avec Marx qu’Adorno voit l’importance réelle et matérielle de sa critique de la métaphysique et de l’ontologie, ainsi que la possibilité de résister aux forces de la domination sociale.

The Laws is the longest and, according to tra-dition, the last of Plato’s dialogues. It was left ‘in the wax’ at the time of Plato’s death and brought into publication by Philip of Opus (D. L. 3.37). Whether Philip had a hand in editing the work or whether he merely tran-scribed it is uncertain (for one recent account, see Nails and Thesleff 2003). The most recent analyses of its style indicate significant affini-ties with the Sophist, Politicus and Philebus, though there (...) are stark differences in places. These, however, might be explained in vari-ous ways, and there has never been any ques-tion that the Lg. substantially contains the thought of Plato. If we set special problems of composition aside, including admittedly serious questions about the overall coher-ence of the dialogue, then the chief difficul-ties remaining for an interpreter of the Lg. include (a) its dramatic date and structure, (b) its relation to other political dialogues of Plato, especially the Republic and the Plt. and (c) the extensive discussion of cosmology and theology in L. bk 10.

The lectures on American pragmatism given by the French sociologist Emile Durkheim in 1913 in Paris were first published in French in 1955 and finally translated into English and published in 1983 as Pragmatism and Sociology. For obvious reasons they have attracted considerable attention from philosophers and sociologists, especially the latter, in both continental Europe and the English speaking world. Durkheim's motives in giving the lectures have been scrutinized, his interpretations of the pragmatists widely discussed and his criticisms of William (...) James, John Dewey, and F. S. C. Schiller have met with mixed receptions. However, after years of scholarly discourse on his motives, interpretations and criticisms, there is no common agreement on the significance and meaning of Pragmatism and Sociology. We briefly address the disagreement over Durkheim's motives in the introductory section before turning to our interpretation in the body of the article. There we focus on his criticisms of the pragmatists’ views on the aims and nature of knowledge, which is a classic confrontation between French rationalism à la Durkheim and American pragmatism of the James/dewey variant.

In October of 2002, Rick Smalley, Nobel laureate chemist at Rice University, was pondering what to say to a Congressional Hispanic Science and Literacy Forum hearing in Harlingen, Texas. Smalley used the opportunity to craft an all-encompassing justification for science's importance in the modern world-a justification so persuasive and broad it could be presented to any audience on any occasion. Indeed, variants of his talk have since been given some 200 times, from Dallas to Dubai.

I am extremely grateful to Rick Furtak and Alison McQueen for their valuable and challenging comments. My book is long and complicated, and it can hardly have been easy to internalize its details, both philosophical and political. The two authors have a very accurate grasp of my views, and I am delighted by that. I actually do not need to spend my time correcting misstatements of what I say. Both authors offer really interesting challenges to my views, about which (...) it’s a pleasure to think further.Reply to Rick FurtakFurtak is a very subtle thinker about the emotions. What makes his remarks especially illuminating is that he not only understands the nuances of my own position on emotions, especially as I develop it in Upheavals of Thought , but also has a wide-ranging grasp of the philosophical literature on emotions more generally. He poses questions of two sorts. One set concerns emotions of which I suggest that there is something .. (shrink)

Examines how the educations of America's first four presidents, and in particular their scholarly devotion to ancient Greek and Roman classics, informed the beliefs and ideals that shaped the nation's constitution and government.

This brief commentary has three goals. The first is to argue that ‘‘framework debate’’ in cognitive science is unresolvable. The idea that one theory or framework can singly account for the vast complexity and variety of cognitive processes seems unlikely if not impossible. The second goal is a consequence of this: We should consider how the various theories on offer work together in diverse contexts of investigation. A final goal is to supply a brief review for readers who are compelled (...) by these points to explore existing literature on the topic. Despite this literature, pluralism has garnered very little attention from broader cognitive science. We end by briefly considering what it might mean for theoretical cognitive science. (shrink)

We explored the influence of negation on cognitive dynamics, measured using mouse‐movement trajectories, to test the classic notion that negation acts as an operator on linguistic processing. In three experiments, participants verified the truth or falsity of simple statements, and we tracked the computer‐mouse trajectories of their responses. Sentences expressing these facts sometimes contained a negation. Such negated statements could be true (e.g., “elephants are not small”) or false (e.g., “elephants are not large”). In the first experiment, as predicted by (...) the classic notion of negation, we found that negation caused more discreteness in the mouse trajectory of a response. The second experiment induced a simple context for these statements, yet negation still increased discreteness in trajectories. A third experiment enhanced the pragmatic context of sentences, and the discreteness was substantially diminished, with one primary measure no longer significantly showing increased discreteness at all. Traditional linguistic theories predict rapid shifts in cognitive dynamics occur due to the nature of negation: It is an operator that reverses the truth or falsity of an interpretation. We argue that these results support both propositional and contextual accounts of negation present in the literature, suggesting that contextual factors are crucial for determining the kind of cognitive dynamics displayed. We conclude by drawing broader lessons about theories of cognition from the case of negation. (shrink)

Through theoretical discussion, literature review, and a computational model, this paper poses a challenge to the notion that perspective-taking involves a fixed architecture in which particular processes have priority. For example, considerable work has shown that egocentric perspectives can arise more quickly, with other perspectives (such as of task partners) emerging only secondarily. This theoretical dichotomy is challenged here, and we propose a general view of perspective-taking as an emergent phenomenon governed by the interplay among several cognitive mechanisms. We first (...) describe the pervasive relevance of perspective-taking to cognitive science. A dynamical systems model is then introduced which explicitly formulates the timescale interaction proposed. Implications are discussed, with ideas for future empirical research. (shrink)

Using the Godel incompleteness result for leverage, Roger Penrose has argued that the mechanism for consciousness involves quantum gravitational phenomena, acting through microtubules in neurons. We show that this hypothesis is implausible. First the Godel result does not imply that human thought is in fact non-algorithmic. Second, whether or not non-algorithmic quantum gravitational phenomena actually exist, and if they did how that could conceivably implicate microtubules, and if microtubules were involved, how that could conceivably implicate consciousness, is entirely speculative. Third, (...) cytoplasmic ions such as calcium and sodium are almost certainly present in the microtubule pore, barring the quantum-mechanical effects Penrose envisages. Finally, physiological evidence indicates that consciousness does not directly depend on microtubule properties in any case, rendering doubtful any theory according to which consciousness is generated in the microtubules.

Groundhog Day (Harold Ramis, 1993) and Only Lovers Left Alive (Jim Jarmusch, 2013) are fantasy films that use the device of practical immortality in order to raise important philosophical questions about what constitutes a good life and to explore the nature of romantic love. Groundhog Day provides fairly conventional answers about how to live a good life by focusing on issues of spiritual redemption, selflessness, and developing one’s human potential. In contrast, Lovers provides a dark portrayal of a civilization on (...) the brink of extinction but offers a glimmer of hope for the future. The lifestyle and values of married vampires Adam and Eve represent an alternative vision of the core values needed to sustain a better world: greater reliance on human imagination, maintaining a sense of wonder and curiosity about the world, creating and appreciating works of art and living in harmony with the natural world. Both films also offer a perspective on the importance of romantic love in living a good life. Although these perspectives often diverge from one another, they do overlap in some interesting ways. The style of film criticism used in this paper is inspired by the film philosophy of Stanley Cavell. (shrink)
