Reflections on individual and collective experience are a valuable source of knowledge. The jubilee collection “Philosophers 1981. 40 years later. Continuing Storiesˮ presents one of the most emblematic classes in the history of the Faculty of Philosophy of Sofia University “St. Kliment Ohridskiˮ. The collection synthesizes the collective image and mentality of a distinctive generation of philosophers ‒ “active, successful and memorable personalitiesˮ.

It has been argued that numbers are spatially organized along a "mental number line" that facilitates left-hand responses to small numbers, and right-hand responses to large numbers. We hypothesized that whenever the representations of visual and numerical space are concurrently activated, interactions can occur between them, before response selection. A spatial prime is processed faster than a numerical target, and consistent with our hypothesis, we found that such a spatial prime affects non-spatial, verbal responses more when the prime follows a (...) numerical target (backward priming) then when it precedes it (forward priming). This finding emerged both in a number-comparison and a parity judgment task, and cannot be ascribed to a "Spatial-Numerical Association of Response Codes" (SNARC). Contrary to some earlier claims, we therefore conclude that visuospatial-numerical interactions do occur, even before response selection. (shrink)

Learning the structure of event sequences is a ubiquitous problem in cognition and particularly in language. One possible solution is to learn a probabilistic generative model of sequences that allows making predictions about upcoming events. Though appealing from a neurobiological standpoint, this approach is typically not pursued in connectionist modeling. Here, we investigated a sequential version of the restricted Boltzmann machine, a stochastic recurrent neural network that extracts high-order structure from sensory data through unsupervised generative learning and can encode contextual (...) information in the form of internal, distributed representations. We assessed whether this type of network can extract the orthographic structure of English monosyllables by learning a generative model of the letter sequences forming a word training corpus. We show that the network learned an accurate probabilistic model of English graphotactics, which can be used to make predictions about the letter following a given context as well as to autonomously generate high-quality pseudowords. The model was compared to an extended version of simple recurrent networks, augmented with a stochastic process that allows autonomous generation of sequences, and to non-connectionist probabilistic models. We conclude that sequential RBMs and stochastic simple recurrent networks are promising candidates for modeling cognition in the temporal domain. (shrink)

Tsvetan Todorov, in his book Us and Them. French Thinking on Human Diversity, asked the following question: “How does one, how should one relate to those who do not belong to the same community as we do?” This question has been posed somewhat differently by intellectuals of the Americas anxious to develop paradigms of identity that will contribute to the successful construction of a society whose aim is to integrate heterogeneous ethnic groups: “How does one, how should one relate to (...) those who are members of our new society but who live either on its margins or who are frequently considered as different?” The mixed-race (métissage) approach, applied to the Latin Americas situation, was in part a response to this question. Here the “us” did not designate metropolitan Europeans engaged in thinking about the “others,” that is to say non-Europeans, but Latin Americans thinking about relations among various dominant groups and the varying “others” within their own society, since the “others” were part of “us.” The meaning of “us” is equally problematic when applied to North America. “What happens when words like ‘community’ and ‘us’ cease to have the clear and immediate meaning that Todorov seems to ascribe to them?” Sherry Simon recently asked. Although offering a general critique of the monological conception of culture and identity – a critique based on Bakhtin's work on polyphony and dialogism, on James Snead's investigation of the hybrid nature of several texts belonging to the European canon (such as The Odyssey and The Divine Comedy), and on the studies of Angelo Ara and Claudio Magris in regard to the heterogeneity of Trieste – she nevertheless begins her essay on a personal note, describing life in the multicultural city of Montreal, where “many children come out of mixed or immigrant marriages, some going to French schools, some to English,” and who can not “define themselves as products of a single culture” (pp. 15-16). Although I agree with Sherry Simon that the “us” of culture is never a given (it should be mentioned that Todorov himself writes that we must “give up basing our thinking on such a distinction” [between us and them] p. 421), it is essential here to emphasize the special ambiguity of the conception of “us” in the ex-colonies of the New World, where the “collision of cultures” implied not only, on the one hand, a confrontation among Spanish, Portuguese, British, and French colonists, but also between the colonists and the African slaves as well as with the immigrants who arrived after independence. Todorov's conception of nationhood (p. 422) as “a more or less perfect (although never total) coincidence of a State and a culture” - which he toned down a bit by adding that a culture is often identified with a particular region, a group of countries, or even a stratum of the population (pp. 424-425) - is even less applicable to the new societies of America than it is to Europe. Not only are we talking about hybrid societies (and what society isn't, to some degree?), but of societies conceived as hybrid, either multicultural (Canada) or mixed-race (Latin America). If, as Ernest Renan insisted at the end of the XIXth century, the idea of the modern nation is based on a conscious disregard for our diverse ethnic origins, the concepts of identity of the societies of the New World have often been based on an explicit symbolization of their heterogeneity.
