Categorical perception (CP) is said to occur when a continuum of equally spaced physical changes is perceived as unequally spaced as a function of category membership (Harnad, S. (Ed.) (1987). Psychophysical and cognitive aspects of categorical perception: A critical overview. Cambridge: Cambridge University Press). A common suggestion is that CP for color arises because perception is qualitatively distorted when we learn to categorize a dimension. Contrary to this view, we here report that English speakers show no evidence of lowered discrimination (...) thresholds at the boundaries between blue and green categories even though CP is found at these boundaries in a supra-threshold task. Furthermore, there is no evidence of different discrimination thresholds between individuals from two language groups (English and Korean) who use different color terminology in the blue-green region and have different supra-threshold boundaries. Our participants' just noticeable difference (JND) thresholds suggest that they retain a smooth continuum of perceptual space that is not warped by stretching at category boundaries or by within-category compression. At least for the domain of color, categorical perception appears to be a categorical, but not a perceptual phenomenon. (shrink)

We review evidence that language is involved in the establishment and maintenance of adult categories of facial expressions of emotion. We argue that individual and group differences in facial expression interpretation are too great for a fully specified system of categories to be universal and hardwired. Variations in expression categorization, across individuals and groups, favor a model in which an initial “core” system recognizes only the grouping of positive versus negative emotional expressions. The subsequent development of a rich representational structure (...) may require the integration of a verbal categorization system with a perceptual processing system that is category-agnostic. Such a model may reconcile many strands of apparently conflicting behavioral, physiological, and neuroscience evidence concerning our understanding of facial expressions of emotion. (shrink)

Articles on comparative philosophy; includes articles on Indic philosophy.

The Mahabharata, one of the major epics of India, is a sourcebook complete by itself as well as an open text constantly under construction. This volume looks at transactions between its modern discourses and ancient vocabulary. Located amid conversations between these two conceptual worlds, the volume grapples with the epic's problematisation of dharma or righteousness, and consequently, of the ideal person and the good life through a cluster of issues surrounding the concept of agency and action. Drawing on several interdisciplinary (...) approaches, the essays reflect on a range of issues in the Mahabharata, including those of duty, motivation, freedom, selfhood, choice, autonomy, and justice, both in the context of philosophical debates and their ethical and political ramifications for contemporary times. This book will be of interest to scholars and researchers engaged with philosophy, literature, religion, history, politics, culture, gender, South Asian studies, and Indology. It will also appeal to the general reader interested in South Asian epics and the Mahabharata. (shrink)

In The Selfish Gene, Dawkins (1976) proposed the existence of a unit of cultural inheritance that he called the meme. Some examples of memes are clothing fashions, tool designs, and architectural designs. Like genes, memes must share three properties: longevity, fecundity, and copying-fidelity. Longevity refers to the lifespan of a meme, fecundity to the rate of spread of a meme, and copying-fidelity to how accurately a meme is replicated. In other work (Hardisty and Cassill, in preparation), we hypothesized that successful (...) memes should share a fourth property with successful genes: memes should affect an organism’s lifetime fitness by improving survival or reproduction. Sterelny (2006) argued that high-fitness memes include tools or artifacts that are physically enduring, made from easy to find materials, and easy to reverse-engineer. Here, we argue that another way to link memes to individual fitness is to think of tools as part of an organism’s ecological niche. Each tool or artifact an organism makes that extends its evolutionary lifespan or increases its reproductive output is thus a meme that is directly contributing to that organism’s fitness. (shrink)

This engaging, wide-ranging study in comparative social and political philosophy gives a well-argued account of how ideological and even utopian views, such as normative communication, development and justice, are sociologically rooted. It also shows how this fact has been reflected in the social history of Asian countries like India and China, as well as some Western countries during the last two centuries. To illustrate the underlying concepts, reference is made to influential thinkers, both from the East and West, from Hegel (...) and James Mill to Marx and Maozedong, and from Gandhi to Rawls. The author, himself one of the major contemporary Indian philosophers, offers arguments to show that the right version of cultural relativism is objective and judgeable. Concrete case studies are cited indicating why even fundamental values like indivisible peace and "our own green planet" cannot be practically universalized. Yet this work is a sustained plea for improvable understanding between the East and the West and the transcultural value orientation of different cultures. (shrink)

The intellectual tools every business person needs in the boardroom. Includes two rare essays by Ayn Rand! With government and the media blaming big business for the world economic crisis, capitalism needs all the help it can get. It's the perfect time for this collection of essays presenting a philosophical defense of capitalism by Ayn Rand and other Objectivist intellectuals. Essential and practical, Why Businessmen Need Philosophy reveals the importance of maintaining philosophical principles in the corporate environment at all levels (...) of business from daily operations to executive decisions, and provides the tactical and tactful rational thinking required to defend companies from ideological attacks.

If language is crucial to the development of shared colour categories, how might cultural constraints influence the development of divergent category sets? We propose that communities arrive at different sets of categories because the tendency to group by perceptual similarity interacts with environmental factors (differential access to dying and printing technologies), to make different systems optimal for communication in different situations.

The nature of emotion concepts and whether there are any that are universally “basic” remains controversial, as acknowledged in the article “Language and Emotion.” The suggestion that some emotions are embodied through a process of association between neural networks for bodily sensations (e.g., raised temperature) and neural circuitry dedicated to linguistic metaphor is interesting, but speculative. However, it is a hypothesis that risks relegating speakers of languages that lack sophisticated metaphors to a lower level on some scale of linguistic evolution.

Theories, Technologies, Instrumentalities of Color is the outcome of a workshop, held in Leuven, Belgium, in May 2000.

Problems in peer review, the backbone of maintaining high standards in scientific publishing, have led to wide spread discontent within the scientific community. Training in the peer review process and a simpler format to assist in decision making are possible courses to improve and expedite the process of peer review and scientific publishing. The authors discuss problems in the peer review process focusing on challenges related to major revisions and reviewer's wish list of experiments; this leads to the loss of (...) time and money. Major revisions rarely lead to significant improvements, while simultaneously delay the dissemination of knowledge. The authors propose simple solutions including training peer reviewers to improve the peer review system. (shrink)

Study of Aparokṣānubhūti of Śaṅkarācārya, work on Advaita philosophy.

Th is article examines the extent to which spaces are structuring influences on, or targets of, action. Two factors and their interactions are presented: the extent to which a space is 1) maintained and 2) used. As these factors increase in strength, the structural influences of a space increase while agential opportunities are diminished. Conversely, as spaces become dilapidated and abandoned, structural forces are weakened and the potential for creative action heightens. These spaces can be conceptualized as elements of the (...) ‘residual landscape’: spaces left behind by socio-historical processes and practices. Special cases are considered where the factors are inversely related and issues of structure and agency are complicated. A brief case study serves to illustrate each type of spaceand the factors which operate therein. (shrink)

The book develops the necessary background in probability theory underlying diverse treatments of stochastic processes and their wide-ranging applications. With this goal in mind, the pace is lively, yet thorough. Basic notions of independence and conditional expectation are introduced relatively early on in the text, while conditional expectation is illustrated in detail in the context of martingales, Markov property and strong Markov property. Weak convergence of probabilities on metric spaces and Brownian motion are two highlights. The historic role of size-biasing (...) is emphasized in the contexts of large deviations and in developments of Tauberian Theory. The authors assume a graduate level of maturity in mathematics, but otherwise the book will be suitable for students with varying levels of background in analysis and measure theory. In particular, theorems from analysis and measure theory used in the main text are provided in comprehensive appendices, along with their proofs, for ease of reference. Rabi Bhattacharya is Professor of Mathematics at the University of Arizona. Edward Waymire is Professor of Mathematics at Oregon State University. Both authors have co-authored numerous books, including the graduate textbook, Stochastic Processes with Applications. Advanced undergrads and graduate students, analysts. (shrink)

Corporate social responsibility positively impacts relationships between firms and customers. Previous research construes this as an outcome of customers’ warm glow that results from supporting firms’ benevolence. The current research demonstrates that beyond warm glow, CSR positively impacts firms’ sales through mitigating their customers’ perceptions of purchase risk. We demonstrate this effect across three conditions in which customers’ perceived risk of purchase is heightened, using both secondary data and two lab experiments. Under conditions of greater purchase risk, CSR positively impacts (...) both sales and customer purchase intentions to a greater extent than in conditions of lower purchase risk. In addition to measuring purchase risk as the mediating process behind these effects, we demonstrate that the effect of CSR on sales is stronger for those CSR activities that signal a stakeholder orientation.

Two words, pañcagupta and kuṇḍakīṭa, are found in modern Sanskrit lexicons such as the Śabdakalpadruma, the Vācaspatya, the Sanskrit-Wörterbuch, and A Sanskrit English Dictionary. They are said to signify the Cārvāka philosophy and an expert in the Cārvāka philosophy respectively. Both the words have been taken from some twelfth-century Sanskrit kośas but no example of actual use is available. Nor do they occur in any earlier Sanskrit kośa, such as the Amarakośa and the Halāyudhakośa. The inference is that the words (...) must have appeared in some late philosophical work that was critical of the materialist Cārvāka system of philosophy and the kośakāras found them in the same source.
