Little is known about distance processing in patients with posterior brain damage. Although many investigators have claimed that distance estimates are normal or abnormal in some of these patients, many of these observations were made informally and the examiners often asked for relative, and not absolute, distance estimates. The present investigation served two purposes. First, we wanted to contrast the use of distance information in peripersonal space for perceptual report as opposed to visuomotor control in our visual form agnosic patient, (...) DF. Second, we wanted to see to what extent her abilities to process distance cues were dependent on binocular vision, in light of Milner et al.'s (1991) observations of preserved stereopsis in DF, and Dijkerman et al.'s (1996) and Marotta et al.'s (1997) observations that her visual guidance of grasping may be particularly dependent on binocular vision of the target. We hypothesized that DF's visuomotor responses would show normal sensitivity to target distance, while her perceptual estimates would not. In the first experiment, we required DF and two age- and sex-matched control subjects to reach out and grasp black cubes placed at varying distances, or to estimate the distance of the cubes from the hand starting position without making a reaching movement. In the second experiment, we required DF and two age-matched control subjects to point as rapidly and accurately as possible to small LED targets which differed in spatial location, under binocular and monocular conditions. The results showed that, relative to the control subjects, DF's grasping movements produced normal peak velocity-distance scaling-when she reached for blocks which varied in depth or pointed to LED targets which were presented at different distances in depth. In contrast, in the cube experiment, her verbal estimates of object distance were poorly scaled, although they improved slightly under the binocular conditions. The results are discussed in terms of current theories of processing streams in extrastriate visual cortex and the distinction between categorical and coordinate spatial processing. (shrink)

Evolutionary psychology and human sociobiology often reject the mere possibility of symbolic causality. Conversely, theories in which symbolic causality plays a central role tend to be both anti-nativist and anti-evolutionary. This article sketches how these apparent scientific rivals can be reconciled in the study of disgust. First, we argue that there are no good philosophical or evolutionary reasons to assume that symbolic causality is impossible. Then, we examine to what extent symbolic causality can be part of the theoretical toolbox of (...) the evolutionary social sciences. This examination leads to the conclusion that it is possible to make evolutionary sense of Mary Douglas’s theory of disgust, and that her view of symbolic causality can and should inform evolutionary theories of (sociocultural) disgust.

The monograph shows that in the last 50 years theoretical linguistics remains a compendium of mutually contradicting doctrines on multiple levels: the level of general theories of language, the level of its main constituents (the lexicon, syntax, and the lexical-syntactic interface that connects them), and the lower levels of specific linguistic problems (such as lexical polysemy, grammatical meanings, etc.). The contradictions of contemporary linguistic theories are indicative of a deep crisis. Evolutionary-synthetic theory of language is aimed at overcoming this crisis. (...) It implements a multidisciplinary approach that describes the language a) in evolutionary and ontogenetic development and b) in close interaction with other human subsystems: the mental representation of the world, human activity and social interaction. Language is defined as a dual system developing in ontogeny: 'universal sensory sublanguage + ethnically specific functional sublanguage' where the sensory sublanguage is used to describe the 'visible' world (accessible to the senses), and the functional sublanguage is employed to describe the conceivable world ('comprehended by human mind'). Within the framework of the approach presented, many problems are solved: 1) the cognitive (non-verbal) language for representing language meanings; 2) diversity and unity of languages (using the structure alternative to Chomsky's Universal Grammar); 3) the main (original) function of the language; 4) the cognitive language of thought (its basis is the lexical and grammatical meanings of the sensory sublanguage); 5) dual (functionally prototypical) structure of human categories; 6) mechanisms in the early acquisition of lexical and grammatical meanings; 7) the meaning (assignment) of the syntactic structure of a sentence, etc. The book deals with a wide range of issues related to human cognition, glottogenesis and anthropogenesis, universal cognitive structures for the representation of objects, actions and situations, so it will be of interest not only to linguists, but also to psychologists, anthropologists, sociologists, philosophers.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

That a coherent account of the origins and early history of the British Association for the Advancement of Science has yet to be written is not altogether surprising. Even when the facts of the matter have been retrieved from the scattered papers of Babbage, Brewster, J. D. Forbes, Murchison, John Phillips, Vernon Harcourt, Whewell, and the rest, their organization into a connected whole remains a formidable business. The present paper seeks to identify the roles played in this important chapter in (...) the chronicles of British science by David Brewster (1781–1868), the Scottish natural philosopher, and William Vernon Harcourt (1789–1871), the York clergyman. Inquiries of this kind—into the proper apportioning of the credit for a discovery, a technique, or the rise of an institution—are only saved from sterility if they make possible a better understanding of the critical events. The present review of the origins of the British Association leads to the modest but important conclusion that the organization brought into existence by Vernon Harcourt at York in September 1831 was subtly but significantly different from that which had originally been proposed by Brewster. If this is so, some of the existing accounts of the matter stand in need of revision. (shrink)

For over a century we have attempted to understand human aesthetic experience using scientific methods. A typical experiment could be described as reductive and quasi-psychophysical. We vary some aspect of the stimulus and systematically measure some aspect of the aesthetic response. The limitations of this approach can be categorized as problems on the Y axis and the X axis. The most enigmatic components of aesthetic experience include inclination to cry, aesthetic rapture, a sense of the sublime, and intense fascination. However, (...) we cannot evoke these 'hot' aesthetic emotions in the lab, at least not with well controlled stimuli on multiple trials. We thus resort to measuring cold, cognitive preference ratings. There are also problems on the X axis. The reductive psychophysical approach explicitly assumes that there are lawful relations between different stimulus dimensions and preferences. It also tacitly assumes that these dimensions are independent and orthogonal. The second assumption is implausible. Whatever stimulus-preference laws we discover are likely to be twisted and modulated when another dimension is added to the stimuli. This 'gestalt nightmare' has long been recognized, but never resolved. This matters, because human aesthetic faculties are probably tuned to the balance and relationship of parts which make up a whole and are indifferent to the parts presented in isolation. I conclude that the future of scientific aesthetics depends on how successfully we can transcend reductive, quasi-psychophysical approaches. (shrink)

The process of merging the political, economic and media power in Italy and the role of the Italian prime minister Silvio Berlusconi are discussed. “La Repubblica” and “L’Unita” publications are investigated (2009–2010) and compared via the famous European media as “The Financial Times”, “The Times”, “The Independent”, ”Le Monde”, “La Liberation”, “Le Nouvel Obstrvateur”, “El Pais” and “Der Spigel”. In particular the author pays the attention to polemics devoted to the information freedom protection. The existence of media empires in modern (...) mass media hinders one of the main functions of the press, namely the spreading of objective and full information on all sides of the society life directed by plurality in informational and analytical material. At the same moment in time the mass media influence on the fates of the leading political figures, Silvio Berlusconi in particular. A topical problem of complex relations of modern press and different political, social and power structures is analyzed on the Italian example. (shrink)

This paper considers the claim that perceptual experience is “transparent”, in the sense that nothing other than the apparent public objects of perception are available to introspection by the subject of such experience. I revive and strengthen the objection that blurred vision constitutes an insuperable objection to the claim, and counter recent responses to the general objection. Finally the bearing of this issue on representationalist accounts of the mind is considered.
