We implemented a Choice Blindness Paradigm containing political statements in Argentina to reveal the existence of categorical ranges of introspective reports, identified by confidence and agreement levels, separating easy from very hard to manipulate decisions. CBP was implemented in both live and web-based forms. Importantly, and contrary to what was observed in Sweden, we did not observe changes in voting intentions. Also, confidence levels in the manipulated replies where significantly lower than in non-manipulated cases even in undetected manipulations. We name this phenomenon unconscious detection of self-deception. Results also show that females are more difficult to manipulate than men.

We present the results of a gamified mobile device arithmetic application which allowed us to collect vast amount of data in simple arithmetic operations. Our results confirm and replicate, on a large sample, six of the main principles derived in a long tradition of investigation: size effect, tie effect, size-tie interaction effect, five-effect, RTs and error rates correlation effect, and most common error effect. Our dataset allowed us to perform a robust analysis of order effects for each individual problem, for which there is controversy both in experimental findings and in the predictions of theoretical models. For addition problems, the order effect was dominated by a max-then-min structure (i.e 7+4 is easier than 4+7). This result is predicted by models in which additions are performed as a translation starting from the first addend, with a distance given by the second addend. In multiplication, we observed a dominance of two effects: (1) a max-then-min pattern that can be accounted by the fact that it is easier to perform fewer additions of the largest number (i.e. 8x3 is easier to compute as 8+8+8 than as 3+3+…+3) and (2) a phonological effect by which problems for which there is a rhyme (i.e. "seis por cuatro es veinticuatro") are performed faster. Above and beyond these results, our study bares an important practical conclusion, as proof of concept, that participants can be motivated to perform substantial arithmetic training simply by presenting it in a gamified format.

The aim of this study was to determine the effect of two arm swing techniques, the simultaneous arm swing and the early arm swing, on vertical countermovement jump performance and on the contribution of the arms to vertical movement at the centre of mass (CM) during the propulsion phase. Participants were 28 athletes practicing sports in which the vertical jump constitutes a basic ability. Ground reaction forces were recorded by a force platform and the sagittal plane motion was recorded by a video camera. Although at take-off the vertical velocity (2.7 +/- 0.2m/s for simultaneous technique vs. 2.8 +/- 0.2m/s for early technique; p = 0.040) and position (1.18 +/- 0.06m for simultaneous vs. 1.17 +/- 0.05m for early; p = 0.033) of the CM were significantly different, no difference was observed in jump height (1.56 +/- 0.01m in both techniques). The arm action differed during the initial and final propulsion phases in both styles but the accumulated vertical contribution was similar. The practical implication in sports is that the use of the arm-swing technique to reach the maximum jump height should be determined by tactical demands instead of the technical execution of the arms.

ResumenEn el siguiente artículo, me propongo explicar y analizar las que me parecen ser las tesis filosóficas principales del libro de Pablo Oyarzún Entre Celan y Heidegger, así como proponer algunas pistas para reflexionar en torno a problemáticas relevantes que esta obra contribuye a identificar y a formular. Dos son los principales argumentos que elaboro con el fin de llevar a cabo este trabajo. El primero concierne el concepto de "sentido", que Oyarzún intenta desarrollar en tensión con lo que entiende ser la "lectura hermenéutica" de la poesía de Celan (y de la poesía en general), que presupone según él que el poema, como cualquier otra creación de lenguaje, quiere decir algo y por lo tanto es portador de significados accesibles para la comprensión. Frente a eso, Oyarzún opone la inaccesible insignificancia del lenguaje poético, la "pizca" de sentido cuya propiedad fundamental consiste en irrumpir en medio de la circulación y transmisión de sentido y resistir a la comprensión -pero, de ese modo, la posibilita como comprensión, dado que solo lo que la resiste logra ponerla en movimiento. El segundo argumento concierne a la significación del "dolor", que precisamente no ha de poseer ninguna "significación", so pena de ser neutralizado y obliterado como dolor. Solo la absurda crudeza del dolor, a título de acontecimiento traumático que retorna excediendo la identidad temporal de una conciencia colectiva -es la función de la "data" en la poesía de Celan-, puede dar origen a una memoria y a una historia auténticas.
