Cranial electrotherapy stimulation is a neuromodulation tool used for treating several clinical disorders, including insomnia, anxiety, and depression. More recently, a limited number of studies have examined CES for altering affect, physiology, and behavior in healthy, non-clinical samples. The physiological, neurochemical, and metabolic mechanisms underlying CES effects are currently unknown. Computational modeling suggests that electrical current administered with CES at the earlobes can reach cortical and subcortical regions at very low intensities associated with subthreshold neuromodulatory effects, and studies using electroencephalography (...) and functional magnetic resonance imaging show some effects on alpha band EEG activity, and modulation of the default mode network during CES administration. One theory suggests that CES modulates brain stem, limbic, and cortical regions and increases relative parasympathetic to sympathetic drive in the autonomic nervous system. There is no direct evidence supporting this theory, but one of its assumptions is that CES may induce its effects by stimulating afferent projections of the vagus nerve, which provides parasympathetic signals to the cardiorespiratory and digestive systems. In our critical review of studies using CES in clinical and non-clinical populations, we found severe methodological concerns, including potential conflicts of interest, risk of methodological and analytic biases, issues with sham credibility, lack of blinding, and a severe heterogeneity of CES parameters selected and employed across scientists, laboratories, institutions, and studies. These limitations make it difficult to derive consistent or compelling insights from the extant literature, tempering enthusiasm for CES and its potential to alter nervous system activity or behavior in meaningful or reliable ways. The lack of compelling evidence also motivates well-designed and relatively high-powered experiments to assess how CES might modulate the physiological, affective, and cognitive responses to stress. Establishing reliable empirical links between CES administration and human performance is critical for supporting its prospective use during occupational training, operations, or recovery, ensuring reliability and robustness of effects, characterizing if, when, and in whom such effects might arise, and ensuring that any benefits of CES outweigh the risks of adverse events.

The present studies examined whether implied tactile properties during language comprehension influence subsequent direct tactile perception, and the specificity of any such effects. Participants read sentences that implicitly conveyed information regarding tactile properties (e.g., Grace tried on a pair of thick corduroy pants while shopping) that were either related or unrelated to fabrics and varied in implied texture (smooth, medium, rough). After reading each sentence, participants then performed an unrelated rating task during which they felt and rated the texture of (...) a presented fabric. Results demonstrated that the texture properties implied in sentences influence direct tactile perception. Specifically, after reading about a smooth or rough texture, subsequent fabric ratings became notably smoother or rougher, respectively. However, we also show that there was some specificity to these effects: Fabric-related sentences elicited more specific and interactive effects on subsequent ratings. Together, we demonstrate that under certain circumstances, language comprehension can prime tactile representations and affect direct tactile perception. Results are discussed with regard to the nature and scope of multimodal mental simulation during reading. (shrink)

Learning a novel environment involves integrating first-person perceptual and motoric experiences with developing knowledge about the overall structure of the surroundings. The present experiments provide insights into the parallel development of these egocentric and allocentric memories by intentionally conflicting body- and world-centered frames of reference during learning, and measuring outcomes via online and offline measures. Results of two experiments demonstrate faster learning and increased memory flexibility following route perspective reading (Experiment 1) and virtual navigation (Experiment 2) when participants begin exploring (...) the environment on a northward (vs. any other direction) allocentric heading. We suggest that learning advantages due to aligning body-centered (left/right/forward/back) with world-centered (NSEW) reference frames are indicative of three features of spatial memory development and representation. First, memories for egocentric and allocentric information develop in parallel during novel environment learning. Second, cognitive maps have a preferred orientation relative to world-centered coordinates. Finally, this preferred orientation corresponds to traditional orientation of physical maps (i.e., north is upward), suggesting strong associations between daily perceptual and motor experiences and the manner in which we preferentially represent spatial knowledge.

Working memory is the system responsible for maintaining and manipulating information, in the face of ongoing distraction. In turn, WM span is perceived to be an individual-differences construct reflecting the limited capacity of this system. Recently, however, there has been some evidence to suggest that WM capacity can increase through training, raising the possibility that training can functionally alter the neural structures supporting WM. To address the hypothesis that the neural substrates underlying WM are targeted by training, we conducted a (...) meta-analysis of functional magnetic resonance imaging studies of WM training using Activation Likelihood Estimation. Our results demonstrate that WM training is associated exclusively with decreases in blood oxygenation level-dependent responses in clusters within the fronto-parietal system that underlie WM, including the bilateral inferior parietal lobule, middle and superior frontal gyri, and medial frontal gyrus bordering on the cingulate gyrus. We discuss the various psychological and physiological mechanisms that could be responsible for the observed reductions in the BOLD signal in relation to WM training, and consider their implications for the construct of WM span as a limited resource.

Acute exercise consistently benefits both emotion and cognition, particularly cognitive control. We evaluated acute endurance exercise influences on emotion, domain-general cognitive control, and the cognitive control of emotion, specifically cognitive reappraisal. Thirty-six endurance runners, defined as running at least 30 miles per week with one weekly run of at least 9 miles (21 female, age 18-30 years) participated. In a repeated measures design, participants walked at 57% age-adjusted maximum heart rate (HRmax) (range 51-63%) and ran at 70% HRmax (range 64-76%) (...) for 90 minutes on two separate days. Participants completed measures of emotional state and the Stroop test of domain-general cognitive control before, every 30 minutes during, and 30 minutes after exercise. Participants also completed a cognitive reappraisal task after exercise. Functional near-infrared spectroscopy tracked changes in oxygenated and deoxygenated hemoglobin levels in the prefrontal cortex (PFC). Endurance exercise elevated positive emotion and cognitive reappraisal success. Endurance exercise reduced Stroop response time and test-evoked PFC oxygenation during exercise. Results suggest that even at relatively moderate intensities, endurance athletes benefit emotionally from running both during and after exercise, and task-related prefrontal cortex oxygenation reductions do not appear to hinder prefrontal-dependent cognitive control.

The acuity of T.B.’s shorter contributions to Stoic ethics in the last decade was certainly sufficient reason to greet with satisfaction the book in which he finally offers his overall interpretation of the subject. His previously published arguments were evidently based on a thorough general view without which it was sometimes difficult to appreciate their full strength. The extent to which T.B. is generous this time in giving his general view is obvious from the title of the book. T.B. atte...

In this chapter I consider the relation of history of philosophy to the history of science. I argue that though these two disciplines are naturally linked, they also have special commitments that distinguish each from the other. I begin with the history of the history of science, a discipline that was once allied with philosophy of science but that has increasingly evolved toward social history. Then I consider the debate over whether the history of philosophy is essential for, or rather (...) largely irrelevant to, contemporary “analytic” philosophy. My conclusion is that the relation of history of philosophy to philosophy is best conceived in terms of the relation of history of science to history. Finally, I consider a particular case study of the relation of history of science to history of philosophy that concerns contextualist scholarship on early modern philosophy and science. (shrink)

Tad Brennan explains how to live the Stoic life--and why we might want to. Stoicism has been one of the main currents of thought in Western civilization for two thousand years: Brennan offers a fascinating guide through the ethical ideas of the original Stoic philosophers, and shows how valuable these ideas remain today, both intellectually and in practice. He writes in a lively informal style which will bring Stoicism to life for readers who are new to ancient philosophy. The Stoic (...) Life will also be of great interest to philosophers and classicists seeking a full understanding of the intellectual legacy of the Stoics. (shrink)

AtCharmides163, Critias attempts to extricate himself from refutation by proposing a Prodicean distinction betweenpraxisandpoiēsis. I argue that this distinction leads him further into contradictions.

This chapter is a re-consideration of the powerful set of objections to the Cartesian theory of mind that Princess Elisabeth offered in her 1643–49 correspondence with Descartes. Much of the scholarly discussion of this correspondence has focused on Elisabeth’s initial criticisms of Descartes’ views of mind–body interaction and union, and has presented these criticisms as assuming the general principle that objects with heterogeneous natures cannot interact. However, this account of the criticisms fails to capture not only their basic import, but (...) also their connections to Elisabeth’s remarks later in the correspondence regarding both the ability of rational deliberation to lead us to happiness, and the freedom of our will from determining conditions. The attempt here is to offer a new account of Elisabeth’s objections to Cartesian interaction that serves to relate them to her critical evaluation of Descartes’ views of happiness and freedom. Such an account leads us to see Elisabeth as challenging Descartes throughout to take seriously the extent to which our mind is not merely a rational thinking thing, but also something that is profoundly conditioned by the passions that it receives from the body.

There is an extensive body of literature detailing the forces behind and experiences of alienation in a modern capitalist world. However, social scientific interest in alienation had become parochial and balkanized by the 1970s. To reconstruct a unifying theory of alienation that addresses general features of capitalism, such as compulsory growth and commodification, and particular phases like financialized capitalism, we begin with the notion of futurelessness. Futurelessness refers to a deficient relationship to the future in which people’s senses of possibility (...) ossify, narrow, or dissipate. It may result from inclusion in and exclusion from capitalist mechanisms or processes. Moreover, processes of inclusion and exclusion may appear more voluntary or involuntary. With these general terms, we identify four manifestations of futurelessness in financial capitalism: commercial exhaustion, imaginative marginalization, therapeutic nowism, and pragmatic denialism. The conclusion addresses future-sustenance in an alienating world and the prospects of a more systemic and synthetic approach to alienation. (shrink)

A proper First Law energy balance of the soybean biodiesel cycle shows that the overall efficiency of biodiesel production is 0.18, i.e., only 1 in 5 parts of the solar energy sequestered as soya beans, plus the fossil energy inputs, becomes biodiesel. Soybean meal is produced with an overall energetic efficiency of 0.38, but it is not a fossil fuel. If both biodiesel and soybean meal were treated as finished fossil fuels, the overall energy efficiency of their production would be (...) 0.56, ∼ 40% higher than the average overall efficiency, 0.4, of producing ethanol and DDGS from corn patzek 2006z, patzek 2007a. This difference is caused by the high energy efficiency of producing soybean meal, which is 57% of soya beans by mass. Production of corn ethanol alone, with the average overall efficiency of 0.25, is more energy-efficient than production of biodiesel from soybeans with the overall efficiency of 0.18. The results of the current analysis are compared with those by NREL 1998 and Hill et al. 2006. (shrink)

Many psychiatric disorders are characterized by problems with emotion regulation. Well-known therapeutic interventions include exclusively discursive therapies, like classical psychoanalysis, and exclusively noncognitive therapies, like psycho-pharmaceuticals. These forms of therapy are compatible with different theories of emotion: discursive therapy is a natural ally of cognitive theories, like Nussbaum’s, according to which emotions are forms of judgment, while psycho-pharmacological intervention is a natural ally of noncognitive theories, like Prinz’s, according to which emotions are forms of stimulus-dependent perception. I explore a third (...) alternative: the therapeutic regulation of emotion as the development of metacognitive skills. This is a natural characterization of newer forms of therapy that are increasingly prescribed, like so-called Third-Wave Cognitive Behavioral Therapy and other mindfulness-inspired interventions. I argue that these newer forms of therapy make sense if we conceive of emotion as neither a form of judgment nor a form of perception, but, rather, as a variety of what Gendler calls “alief ”. As Gendler notes, although aliefs do not succumb to direct rational regulation, they can be trained. Thus, if we conceive of emotions as aliefs, we can make sense of their therapeutic regulation through the development of metacognitive skills. Drawing on recent philosophical analyses of skill, as well as empirical paradigms in emotion regulation, and Buddhist characterizations of meditative practice, I sketch a characterization of metacognitive skill, and conclude with some reflections on the advantages of conceiving of psychotherapy as the development of metacognitive skills.

Though the publication of Kuhn's 'Structure of Scientific Revolutions' seemed to herald the advent of a unified study of the history and philosophy of science, it is a hard fact that history of science and philosophy of science have increasingly grown apart. Recently, however, there has been a series of workshops on both sides of the Atlantic (called '&HPS') to bring historians and philosophers of science together to discuss integrative approaches. This is therefore an especially appropriate time to explore the (...) problems with and prospects for integrating history and philosophy of science. The original essays in this volume, all from specialists in the history of science or philosophy of science, offer such an exploration from a wide variety of perspectives. The volume combines general reflections on the current state of history and philosophy of science with discussion of the relation between the two disciplines in specific historical and scientific cases"--Publisher's description, back cover.

Greek Philosophers of the Hellenistic Age examines an important but frequently neglected group of philosophers writing after Aristotle between the third and first centuries B.C. The work of a distinguished intellectual historian, this book is based on an erudite reading of a vast number of primary sources: the Greek and Latin writings of the philosophers, and the fragments, paraphrases, and testimonies from their lost works. Kristeller explores the thought of Epicurus; Zenon and Cleanthes, the founder of the Stoic school and (...) his successor; Pyrrhon and Arcesilaus, the founder of Skepticism and the philosopher who introduced it into the Platonic Academy; and Chrysippus, the third head of the Stoic school and its most important representative. Other figures include Carneades and Philo of Larissa, the second and third representatives of Skepticism in the Platonic Academy, respectively; Panaetius, the first leader of Middle Stoicism; and Antiochus of Ascalon, the head of the Academy, who led it back from Skepticism and prepared Middle Platonism, which paved the way for Neoplatonism. Originally presented as a series of lectures before the Scuola Normale Superiore in Pisa, Italy, Greek Philosophers of the Hellenistic Age assesses a group of philosophers who exerted an enormous influence upon pagan and Christian writers of late antiquity - including Cicero and St. Augustine - and on many medieval and early modern philosophers, theologians, and other thinkers.

In lieu of an abstract, here is a brief excerpt of the content:What Has Cartesianism To Do with Jansenism?Tad M. SchmaltzMy title is modeled on the famous query of the third-century theologian, Tertullian: “What has Athens to do with Jerusalem?” Tertullian’s question asks what pagan Greek learning has to do with the theology of the early Church. By comparison my question asks what philosophical Cartesianism has to do with theological Jansenism, and more specifically what these movements had to do with (...) each other in the France of Louis XIV. To anticipate, the answer is: not much and plenty. I say not much, in the sense that there are profound differences in the approaches and interests of the namesakes of these two movements: in the case of Cartesianism, the French critic of scholastic natural philosophy, René Descartes, and in the case of Jansenism, the Louvain critic of Jesuit theology, Cornelius Jansen (Jansenius). Yet I also say plenty, in the sense that there was in the second half of the seventeenth century a fairly widespread belief in France of an intimate link between the two movements that the work of Descartes and Jansen inspired. What we need here is a story that shows how despite the differences between these two thinkers, their French followers were commonly associated with each other.In order to tell such a story I need to consider some basic difficulties in pinning down the nature of the movements themselves. There are of course familiar problems with the appeal to generic “isms” in the history of ideas, but I also want to consider special concerns pertaining to the definition of French Jansenism and French Cartesianism. In the course of this consideration I suggest that since both movements are to some extent constructs that emerged from intellectual battles in late-seventeenth-century France, they must be understood in light of the political, theological, and philosophical goals of the polemicists involved in these battles.Perhaps the most obvious reason for the connection between the Jansenist and Cartesian movements is that one of the most prominent of the Jansenist theologians, the Port-Royalist Antoine Arnauld, was also an enthusiastic defender [End Page 37] of Descartes’s metaphysical system. But while Arnauld undoubtedly played an important role in the emergence of this link, I think that the full story of its emergence must include a consideration of the different role played by a somewhat neglected figure in the history of early modern Cartesianism, namely, the Lorraine Benedictine Robert Desgabets (1610–78). Desgabets was more deeply involved than Arnauld in the 1671 “Eucharist affair,” which was important for the polemical linkage of Jansenism to Cartesianism in France. Whereas Arnauld attempted to separate Jansenist theology from Cartesian philosophy, Desgabets tried to provide Cartesian foundations for a theology with strong Jansenist overtones. It was Desgabets more than Arnauld, then, who was concerned to apply Cartesian principles to issues of importance for the Jansenist theologian.What Has Descartes To Do with Jansen?A primary trigger for the bitter “Jansenist controversies” in France during the seventeenth century was the posthumous publication in 1640 of the Augustinus of Jansen, the late Bishop of Ypres in the Spanish Netherlands. This technical three-volume work attempts to draw from Augustine responses to Pelagian and semi-Pelagian views concerning the prelapsarian state of innocence, the fall from this state, and the grace required to overcome that fall. Jansen’s emphasis is on the pervasive corruption of original sin and on the impossibility of meritorious action that does not derive from God’s grace to the elect. The Jesuits in Louvain saw the work as a throwback to the theses of Michel du Bay (Baius) that Pope Paul V had condemned in 1567 due to pressure exerted by their order, and they made an unsuccessful attempt to stop the publication of the book. 1 After its publication this text drew the suspicion of Cardinal Richelieu, who (correctly) believed Jansen to be the author of Mars Gallicus, an anonymous pamphlet protesting Richelieu’s anti-Habsburg policies. Richelieu chose a theologian of Notre-Dame-de-Paris, Isaac Habert, to launch an attack against the Augustinus. In a series of sermons starting in 1642 Habert criticized Jansen’s assertion of the necessity of contrition... (shrink)

Social scientists have severed social problems from the study of framing work in social movements. This article proposes to rejoin problems and framing work via attention to the phenomenological structure of social problems. By describing basic 1) temporal, 2) spatial, and 3) experiential features of social problems, we facilitate comparisons of different kinds of movements across distinct historical periods and regions. The approach is demonstrated via the example of “slow violence” (Nixon 2011)—suffering that develops gradually across time and extends across (...) space as well as disproportionately afflicts disempowered people. A comparison of two very different historical cases—environmental justice advocacy in the wake of the Union Carbide disaster in Bhopal, India and consumer activism in early twentieth-century America—illustrates how slow violence presents parallel issues with respect to representing the problem and identifying the culprits. On this basis, the argument demonstrates parallels among disparate social movements by including the analysis of the phenomenological structure of social problems into comparative studies of framing work in movements. As such, this article presents analytical possibilities for incorporating experiences of social problems into the study of framing work and social movements. (shrink)
