This paper considers undecidability in the imitation game, the so-called Turing Test. In the Turing Test, a human, a machine, and an interrogator are the players of the game. In our model of the Turing Test, the machine and the interrogator are formalized as Turing machines, allowing us to derive several impossibility results concerning the capabilities of the interrogator. The key issue is that the validity of the Turing test is not attributed to the capability of human or machine, but (...) rather to the capability of the interrogator. In particular, it is shown that no Turing machine can be a perfect interrogator. We also discuss meta-imitation game and imitation game with analog interfaces where both the imitator and the interrogator are mimicked by continuous dynamical systems. (shrink)

Context: Our body schema is not restricted to biological body boundaries (such as the skin), as can be seen in the use of a cane by a person who is visually impaired or the “rubber hands” experiment. The tool becomes a part of the body schema when the focus of our attention is shifted from the tool to the task to be performed. Problem: A body schema is formed through interactions among brain, body, tool, and environment. Nevertheless, the dynamic mechanisms (...) underlying changes in the body schema are still not fully understood. Method: To study the changing conditions of the body schema (e.g., a shift of attention), a simulation model of object discrimination was extended to differentiate between two kinds of sensitivities – sensitivity to an object being directly manipulated and sensitivity to another object being manipulated by the first. The proposed model consisted of windmills with different numbers of vanes. A model agent was required to determine the number of vanes on a windmill by touching the vanes blindly with an arm controlled by a neural network. Placing a second windmill beside the first and gearing the two windmills to move associatively resulted in the agent using the first windmill as a tool with which to discern the number of vanes on the second windmill. In other words, an agent’s body schema can shift from its arm tip to the boundary between the first and second windmills. We then introduced an experiment with a real windmill model to test the hypothesis demonstrated by the theoretical model. Results: We demonstrated that even simple computational agents can have two different sensitivities to the windmills. One agent becomes sensitive to the first windmill and insensitive to the second one. Another agent becomes insensitive to the first windmill and sensitive to the second one by using the first one as a tool. Therefore, we concluded that the boundary of the body schema was extended to the first windmill in the case of the latter agent because paying attention to the task to be performed instead of the tool itself is essential for the tool to be considered as part of the body schema. Analysis of the experiments using a computational model and human experimentation revealed that a shift from an irregular to a regular movement of a windmill is an indication of extension of the body schema. Constructivist content: Our insights are beneficial for enactive cognitive science. This is because an extended body schema questions the Cartesian separation between subject and object, and the self and the environment. (shrink)

A 10 kHz pulsed X-ray generator utilising a hot-cathode triode in conjunction with a new type of grid control device for controlling X-ray duration is described. The energy-storage condenser was charged up to 70 kV by a power supply, and the electric charges in the condenser were discharged to the X-ray tube repetitively by the grid control device. The maximum values of the grid voltage, the tube voltage, and the tube current were −1.5 kV, 70 kV, and 0.4 A, respectively. (...) The duration of the flash X-ray pulse was primarily determined by the time constant of the grid control device and the cut-off voltage of thermoelectrons. The X-ray duration was controlled within a region of less than 1 ms; the X-ray intensity with a pulse width of 0.27 ms, a charged voltage of 70 kV, and a peak tube current of 0.4 A was 0.92 μC kg −1 at 0.5 m per pulse. The maximum repetition rate was about 10 kHz, and the size of the focal spot was about 3.5×3.5 mm. (shrink)

Upshot: In the model simulation and the human experiment, we observed that attention shifted from a tool to a task. This was accompanied by bodily extension. However, our experiments lack a sense of bodily incorporation (the sense of ownership. Based on the valuable commentaries, we would like to discuss the necessary conditions for possible bodily incorporation in terms of redundant degrees of freedom, synchronous visual tactile stimulation, and 1/f noise.

We can easily discriminate self-produced from externally generated sensory signals. Recent studies suggest that the prediction of the sensory consequences of one’s own actions made by forward model can be used to attenuate the sensory effects of self-produced movements, thereby enabling a differentiation of the self-produced sensation from the externally generated one. The present study showed that attenuation of sensation occurred both when participants themselves performed a goal-directed action and when they observed experimenter performing the same action, although they clearly (...) reported that the tones were produced by other during action observation and by themselves during their own action. These results suggest that sensory prediction of action modulates ongoing auditory processing irrespective of who produces the sounds and that the explicit judgment of agency does not necessarily rely on the same mechanisms on which implicit perceptual measures such as sensory attenuation rely.

El vínculo postmodernidad tecnológica/comunicación humana tiene en los mass-media, la TV, el cine, el internet y sus derivados; en las publicaciones sin censura y en la publicidad, herramientas de distorsión educativa y de salud comunitarias. La postmodernidad impacta en la organización social y en la cultura con su dicotomía de racionalismo vs. irracionalismo. La visión kantiana de la ciencia, la moral y el arte en pro de una sociedad más justa, libre y feliz, se desmorona en el intento de «superar (...) la modernidad».La sociedad cibernética burocratiza e impide la libertad del hombre. Los mass media y la sociedad de la comunicación no han generado una sociedad más «transparente» o consciente de sí misma, sino más compleja y caótica. Las dicotomías sujeto-objeto y público-privado hacen al individuo ajeno a su vida, un elemento de ciencia ficción, inmerso en un proceso virtual que lo desplaza a mundos electrónicos. En el éxtasis de la comunicación el medio predomina con su dispersión sobre el mensaje; el saber científico se orienta al desarrollo tecnológico y al poder, destacando su aspecto lingüístico, que no impide que cada vez más se hable y se escriba peor. El impacto de los mass media impulsa conductas antisociales y una «búsqueda de sensaciones intensas», para aplacar estados emocionales derivados del vacío existencial, de la frustración e insatisfacción vital de ciertas poblaciones.La persistencia de la divulgación enajenante, alienadora de la autoconciencia y falseadora de la realidad, no fomenta el desarrollo de una función personal, vincular y social saludables.

El 30 de julio de 1916 se eligieron los representantes para la Convención encargada de elaborar la segunda constitución uruguaya que fijó las reglas de la naciente democracia. En esta elección se utilizaron por primera vez el voto secreto y una versión inédita de representación proporcional. Para explicar por qué se usaron esas reglas y no otras, se utiliza la teoría de los órdenes sociales de Emanuel Adler. Las nuevas reglas recogen en el plano institucional la evolución cognitiva de caudillos (...) y doctores, los protagonistas centrales de la comunidad de práctica democrática uruguaya. Los caudillos fueron aprendiendo en la práctica, por ensayo y error, a competir por el poder pero también a pactar. Los doctores, a partir de esas prácticas pero también de las teorías que circulaban en la época, aportaron el conocimiento reflexivo que recogieron las nuevas normas. De todos modos, no es posible comprender la trayectoria doméstica sin tomar en cuenta la influencia de procesos exógenos. La Convención de Buenos Aires y la Ley Sáenz-Peña tuvieron un impacto profundo en Uruguay. (shrink)

Se ha tratado de desprestigiar al postmodernismo y no se ha valorado su gran contribución a la cultura universal. El postmodernismo empieza a desarrollarse cuando el ser humano se da cuenta que no tan solo sus órganos de los sentidos pueden engañarlo, sino que también su intelecto, razón y sus facultades superiores más preciadas. Las caídas del positivismo y del racionalismo le abrieron la puerta, apoyado por la insuficiencia de la ciencia y la filosofía para entender el universo. La nomología (...) (legalidad) ha tenido que resignarse frente a la ideografía (procesos irrepetibles e irreversibles) para entender el desarrollo universal. La antinomia del mentiroso, el teorema de Gödel, los procesos caóticos, la impredecibilidad, la incertidumbre, son parte de sus elementos sustantivos. El postmodernismo ha condenado a los ideologismos nomológicos o raciales que terminaron en las masacres de la Revolución Francesa, el Nazismo y las dos Guerras Mundiales, entre otros. (shrink)

Este artículo presenta inicialmente algunas referencias en torno a la noción de progreso moral, las cuales habitualmente apuntan a la idea según la cual este, en efecto, se da gracias a un mejoramiento paulatino en la humanidad. Si bien tal afirmación engloba una generalidad, el problema puede permitirse un espacio de discusión más sólido, reconociendo que el progreso es, además, reflexión desde el punto de vista kantiano y deducción de la historia por parte de Fichte. Con todo ello, se busca (...) aportar contenido al afirmar que, si bien estos autores apelan a escenarios morales y teológicos para evaluar el futuro, en rigor sus intereses son los fortalecimientos del Estado de derecho para el caso fichteano y de las instituciones para Kant, lo cual resulta en una suerte de perfectibilidad humana.

En este artículo tratamos sobre los aspectos empíricos y conceptuales en la Genética Mendeliana y analizamos los vínculos entre ellos. Primero discutimos las ventajas de una representación gráfica de las teorías empíricas; luego pormenorizamos la estructura conceptual de la genécica; en seguida, esquematizamos su protocolo experimental, a continuación destacamos los engarces entre ambas representaciones y, por último, proporcionamos una caracterización holista de la práctica genética, donde el representar y el intervenir se encucntran entremezclados.In this article we deal with the conceptual (...) and empirical features of Mendelian Genetics, and analyze the links between them. First we discuss the challenges of portraying empirical theories as graphical representations. We then give a detailed account of the conceptual structure underlying Mendelian Genetics, followed by a schematization of the experimental protocol involved in this line of research. Links between both representations are highlighted. Finally, we provide a holistic characterization of Mendelian practice, where representing and intervening are intertwined. (shrink)
