Este trabalho tem por objetivo investigar a concepção de fer-ramenta cognitiva no contexto da teoria da cognição incorporada e si-tuada . Para isso, partimos das noções de ferramenta e de tecnologia cognitivas propostas, respectivamente, por Dennett e Dascal , através das quais situam a linguagem no contexto evolu-cionário, ressaltando o seu caráter pragmático. Argumentamos que a concepção de ferramenta cognitiva, que para esses autores está inserida num contexto teórico que privilegia o conhecimento proposicional, pode ser ampliada de modo a abarcar (...) o conhecimento não proposicional. Em seguida, com o propósito de ressaltar a relevância do conhecimento não proposicional, apresentamos algumas teses relativas à natureza dos pro-cessos cognitivos que são postuladas pela CIS e pela Epistemologia Ecológica . Tais teses ressaltam que a compreen-são do comportamento inteligente necessita considerar fatores presentes na complexa dinâmica da interação organismo/meio ambiente. Argu-mentamos, ainda que, graças às teses da CIS e da EE conseguiremos entender alguns fenômenos relacionados à aquisição do conhecimento, es-pecialmente em situações nas quais parece se instaurar uma dicotomia entre significado e ação.

If there is life elsewhere in the universe and its level of development is as backward as its terrestrial counterpart, they will probably have sociologists and political scientists constructing and deconstructing social reality. If and when they finally make contact with earth, these pundits will have great difficulty making sense of American race relations, no matter how many studies the Federation will commission to make sense out of the subject. The earth's most developed country, whose success is largely due to (...) its heterogeneity, pragmatism and common sense, does not seem able to deal with differences in skin pigmentation, to the point that its best intellectuals systematically make fools of themselves in explaining it.

The main feature of Whitebook's reply is that he does not give an inch and, more convinced than ever, keeps charging the windmills of redemption and revolution with the same lame theoretical weapons he had previously deployed. Only this time, he seeks reinforcements by appealing to the “heavies”: Habermas, Castoriadis and Heller. Since multiplying zero by any figure still yields zero, no substantive progress has been made. It would be futile to reiterate the same objections once again. Rather, to move (...) the debate beyond dead center it may be helpful to pose new questions, e.g., in terms of the status of the concepts employed and the political consequences they entail.

With an unusually well-orchestrated PR campaign worthy of the slickest mass commodity, Tikkun presents itself as a newjewish progressive magazine to challenge Commentary. But it is well known that many progressive U.S. magazines are largely staffed by Jews and most Jewish intellectuals are generally liberal. This striking redundancy immediately raises suspicion about either its Jewish or its liberal pedigree — or both. The obvious clash between the traditional secularism of progressive thought and the archaic religious appeal casts a shadow both (...) ways. Is it really Jewish or is it really liberal? And if it somehow manages to be both, what does it mean for present Jewish and liberal thought? (shrink)

Frustrated radicals who have managed, over the last 20 years of chaotic growth and revolutionary restructuring of higher education, to translate their “revolutionary rhetoric” only into tenured academic positions, tend to have an ambivalent relation to critical theory. On the one hand, they are irresistibly attracted to it. In a sophisticated scholarly fashion especially appropriate to their new professional status, critical theory addresses all those troublesome cultural questions that were becoming increasingly urgent but which traditional brands of Marxism could not (...) readily tackle through standard materialist approaches. But, on the other hand, they were never able to digest critical theory's discouraging political implications which, for all practical purposes, effectively undermined most radical conventional wisdom and assumptions — assumptions that even such critical theorists as Adorno and Marcuse could not always do without.

Terminally associated with drugs, unbridled hedonism and general irresponsibility, since the late 1960s “radicalism” has been systematically discredited. Today no one thinks of it as having anything to do with “going back to roots” but, at best, as a youthful indiscretion, usually pushed into oblivion by a 30-year mortgage, a couple of kids or, for academics, tenure. Yet the re-examination of foundations remains essential to any critical perspective seeking to transcend the immediacy of the given and to avoid a comfortable (...) conformism which distorts the present by idealizing and hypostatizing it to the level of a universal standard against which all other possible alternatives are judged.

We develop an analysis of the notion of mental representation, in the domain of visual perception, from a Cognitive Science perspective. Emphasis is given on a Connectionist view, according to which mental representations are emergent properties of the interaction between brain-like systems and structured light in the environment. We suggest that such a notion of mental representation indicates a way out of an ancient dispute between Representationalism and Eliminativism regarding the existence of mental representation in the human perceptual system.We develop (...) an analysis of the notion of mental representation, in the domain of visual perception, from a Cognitive Science perspective.

Ênfase é dada ao paradigma Conexionista, ou de Redes Neurais, de acordo com o qual tais representações mentais são descritas como estruturas emergentes da interação entre sistemas de processamento de informação que se auto-organizam - tais como o cérebro - e a luz estruturada no meio ambiente. Sugerimos que essa noção de representação mental indica uma solução para uma antiga polêmica, entre Representacionalistas e Eliminativistas, acerca da existência de representações mentais no sistema perceptual humano.

The McGurk illusion occurs when listeners hear an illusory percept, resulting from mismatched pairings of audiovisual speech stimuli. Hearing a third percept—distinct from both the auditory and visual input—has been used as evidence of AV fusion. We examined whether the McGurk illusion is instead driven by visual dominance, whereby the third percept, e.g., “da,” represents a default percept for visemes with an ambiguous place of articulation, like/ga/. Participants watched videos of a talker uttering various consonant vowels with and without audios (...) of/ba/. Individuals transcribed the CV they saw or heard. In the V-only condition, individuals predominantly saw “da”/“ta” when viewing CVs with indiscernible POAs. Likewise, in the AV condition, upon perceiving an illusion, they predominantly heard “da”/“ta” for CVs with indiscernible POAs. The illusion was stronger in individuals who exhibited weak/ba/auditory encoding. In Experiment2, we attempted to replicate these findings using stimuli recorded from a different talker. The V-only results were not replicated, but again individuals predominately heard “da”/“ta”/“tha” as an illusory percept for various AV combinations, and the illusion was stronger in individuals who exhibited weak/ba/auditory encoding. These results demonstrate that when visual CVs with indiscernible POAs are paired with a weakly encoded auditory/ba/, listeners default to hearing “da”/“ta”/“tha”—thus, tempering the AV fusion account, and favoring a default mechanism triggered when both AV stimuli are ambiguous.

Conventional wisdom has it that there is — or at least there ought to be — a correspondence between theoretical and political positions. But the very labelling of it as conventional wisdom already betrays its falsity. Sure enough, any careful examination of the record readily reveals that this correspondence hardly ever obtains. No such parallel can be drawn for the Hegelians who split into Right and Left wings with qualitatively different positions, e.g., the German Young Hegelians and the British neo-Hegelians (...) at the end of the last century. Nor is that true for Marxists who bifurcated into Social Democrats and Bolsheviks, or for the existentialists who produced Sartre and Merleau-Ponty, as well as Kierkegaard and Marcel. (shrink)
