The study of cognitive development has been, and still is, faced with two fundamental problems. They are connected, and no satisfactory answer has been found to either. The first problem concerns a terminological distinction and the corresponding semantic contents - it is important to be clear about which characteristics make it possible to distinguish percepts from concepts proper. The second problem, which depends on such distinction, consists in determining when and how, in cognitive development, the turn from perceptual categories into (...) concepts occurs. This paper provides a clear and precise answer to both questions. (shrink)

According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

ResumenEn el marco intelectual del Renacimiento hubo una serie de pensadores que se mostraron disconformes con el aristotelismo dominante. La variedad de sus posturas así como lo distinto de sus posicionamientos filosóficos ha podido actuar como obstáculo para poder ver las similitudes que, en torno a la crítica aristotélica, presentan. El caso de Juan Luis Vives y de Gianfrancesco Pico puede resultar paradigmático, a estos se suma con fuerza Francisco Sánchez, quien dedicó una parte importante de su obra (...) Quod nihil scitur a criticar a Aristóteles, aunque más aún a sus comentaristas.Palabras claveFilosofía del Renacimiento, Francisco Sánchez, Juan Luis Vives, Gianfrancesco Pico, aristotelismo, historia de la filosofía.AbstractIn the intellectual frame of the Renaissance, there were some thinkers who did not agree with the Aristotelism prevailing at the time. The variety of their philosophical positions and opinions may have been an obstacle for an approach to their similarities regarding the Aristotelian critic. The case of Juan Luis Vives and Gianfrancesco Pico della Mirandola can be paradigmatic. Also Francisco Sánchez, who strongly joined their position, devoted an important part of his play Quod nihil scitur to criticize Aristotle –although he focused on his commentators above all.KeywordsPhilosophy in the Renaissance, Francisco Sanchez, Juan Luis Vives, Gianfrancesco Pico, Aristotelism, History of Philosophy.

Este ensayo revisa, desde la perspectiva de Berger y Luckmann, un encuentro con la otredad que se vuelve factor determinante en la socialización secundaria de Germán, personaje principal de la novela Fruta verde, donde él es rara avis que no aceptó como naturales ni perpetuas las condiciones imperantes del medio que lo veía adentrarse en la adolescencia rumbo a la madurez.

The trade and technological war initiated in 2018 between China and the United States has increased interest in the possible hegemonic succession. In this paper, starting from the concept of interstate hegemony, a comparative analysis of the material capabilities of each power in five areas: productive, technological, commercial, monetary-financial and military. This analysis makes it possible to quantify whether China can surpass the United States. As a result, it is concluded that China is far from surpassing the United States in (...) the military and monetary-financial areas, but it can compete in the productive, commercial, and certain critical technological sectors.

Los centros educativos son un lugar de convivencia entre diferentes grupos y por ello se producen conflictos. La preguntas que surgen entonces son si sería posible llevar a cabo prácticas educativas que prevengan esos conflictos y que mejoren las relaciones interpersonales. Uno de los procesos educativos capaces de mejorar la convivencia es la participación educativa, a través de la toma de decisiones colectiva en donde todos los miembros escolares puedan tener la misma oportunidad y responsabilidad. Para que éste tipo de (...) participación funcione se necesitan desarrollar ciertos aspectos de relación y facilitarlos con la mediación escolar. Este artículo revisa los mecanismos y procesos de aprendizaje, actitudes y habilidades para la resolución autónoma de conflictos en los entornos educativos. (shrink)

The assessment of learning in the ethical domain is one of the most complex aspects to attend in the educational context. In recent years, character education has contributed greatly to different social disciplines, such as education or nursing. However, the development of this approach has run up against several obstacles and limitations, as there is little evidence regarding its long-term effectiveness or its evaluation. This essay aims to identify some of the main difficulties to assess learning in the ethical domain, (...) as obstacles and possible constraints to Aristotelian-based character education. Methodology is analytical and of a philosophical-educational nature, based on which an argumentative analysis is constructed from the bibliographical review of the contributions of classical and contemporary authors. Results show the existence of four major problems and ten associated subproblems, both of an external nature linked to the contextual factors of assessment, and of an internal nature that affect the essence of the process itself, which highlight the difficulty of carrying out assessments of an ethical kind. Far from proposing a pessimistic position, we argue a realistic vision that allows educators at different educational levels to be aware of the limits and critical points of evaluation in the ethical domain.

El presente artículo dialoga con la perspectiva del profesor de la Universidad de Stanford, John Searle en su perspectiva acerca de la conciencia, los actos de habla en lo que tiene que ver con la creación de hechos institucionales y su tesis emergentista. Esto con la idea de proponer la lectura del filósofo estadounidense en base a una pragmática de la expresión, que identifica al agente como centro de la creación y transformación social, y por tanto de movilización política, al (...) ser el reconocimiento colectivo quien mantiene el orden institucional. Por lo tanto, esa pragmática de la expresión identifica a los agentes como puntos esenciales de la creación del mundo social, desde el punto de vista del libre albedrio y la creación de mundos sociales posibles.

In 1967 Macedonio Fernández proposed new perspectives to read and write the Latin American novel with El museo de la novela de la Eterna. This article will analyze some of the metafictional games which the Argentinean writer played in his great work. At the same time, it will show how these games developed –with their unique style– foundational concepts of Literature Studies, presented in theory streams such as Formalism, Structuralism and Postmodernism.

En 1969, Ernesto Cardenal publica Homenaje a los Indios Americanos. Veintitrés años después, para el quinto centenario del encuentro entre los dos mundos, Cardenal reedita una versión aumentada de este primer homenaje: Los ovnis de oro (1992). En el presente artículo, se visibilizarán, en la lectura de estos dos textos, los mecanismos poéticos que emplea Cardenal para reflexionar sobre su tiempo desde imaginarios y categorías amerindias.

En este artículo nos proponemos exponer, a partir de los límites conceptuales encontrados a los planteamientos arqueo-genealógicos de Michel Foucault, la posibilidad de plantear, en dos momentos –arqueo-genealógico y gubernamental–, una “ética de la insubordinación reflexiva”. Es decir, una “ética de la libertad inmanente” al débil que al decir su palabra, denuncia y al denunciar cuestiona al tirano y su mundo al habar y actuar con –y por– los otros. Esta ética de la intersubjetividad planteada como una ética de la (...) insumisión concertada, crítica y deliberada, pensamos, puede derivar de ciertas “condiciones enunciativas” encontradas en las dos últimas investigaciones concernientes al “decir veraz” o el “hablar franco” expuestos en El gobierno de sí y de los otros y El coraje de la verdad.

The aim of this study was to carry out a psychosocial analysis of child-to-parent violence (CPV) in a sample of school adolescents, considering a set of individual variables (psychological distress, problematic use of social networking sites, and perceived non-conformist social reputation) and family variables (open and problematic communication with parents) according to sex. The sample consisted of 3,731 adolescents (54% boys), aged between 14 and 16 years (M = 14.6 years, SD = 0.567), from the state of Nuevo León, Mexico. (...) The scores of the boys and girls were analyzed to check for differences. Also, correlations between all the study variables were calculated. Finally, a multiple stepwise regression analysis was carried out for the total sample and also for boys and girls separately. Results confirmed the important role of individual variables as predictors of CPV in boys and girls. The main difference between boys and girls was observed in the predictive weight of problematic use of social networking sites, which was higher in girls than in boys. Open communication with the father was a significant factor for predicting the decrease of CPV levels in the case of boys, while open communication with the mother predicted the decrease of CPV in girls. Problematic communication with the mother showed similar values in boys and girls when predicting CPV, however, the predictive weight of problematic communication with the father was higher in girls than in boys. These results are interesting and have important implications for the prevention of CPV. (shrink)

The article deals with the theories of the American philosopher John Searle concerning his embracement of a form of emergentism of the mind and his ideas about consciousness, intentionality with ‘C’, and language as a critique of traditional standpoints closer to positivist theses. Bearing this in mind, the general purpose is to reveal how the philosophy of Searle aims to recover the active role of the agent and, in consequence, the semantic and pragmatic dimensions of language are vindicated, dimensions in (...) which consciousness and intentionality are key to the construction and dynamism of social reality.

Background: The prevalence of anxiety and depression in young students is associated with biosocial factors and scholastic stress. However, few studies have evaluated emotional-affective symptoms that are related to the immune system and antioxidant parameters in young individuals without diagnoses of affective disorders.Aim: This study aims to assess the relationship between emotional-affective symptoms and glutathione concentrations and CD4 and CD8 lymphocyte counts in college students.Methods: College students completed standardized psychometric instruments, including the Perceived Stress Scale, Hamilton Anxiety Scale, Beck Depression (...) Inventory, Familiar Social and Friends Support Scale, and Rosenberg Scale. Blood samples were biochemically analyzed. Analyses of variance were conducted between four groups according to symptom severity.Results: A considerable prevalence of stress, anxiety, and depression symptoms was observed and negatively correlated with self-esteem and socio-familiar support. Perceived stress was sexually dimorphic. Although biochemical parameters were within reference ranges, glutathione, CD4, and CD8 tended to be lower in participants with anxiety and depression symptoms, which may be of predictive value.Conclusion: The relationship between antioxidant/immune parameters and socio-affective scores is latent in undiagnosed college students who might develop affective disorders. The findings suggest that during the initial development of affective disorders, stress management strategies should be implemented to help college students cope with the academic load and monitor negative changes in their physiological state.

En la educación médica cubana se ha diseñado un currículo para el cumplimiento de su encargo social donde se inserta la enseñanza del inglés. Actualmente constituye una prioridad trabajar en la búsqueda de estrategias que favorezcan el perfeccionamiento idiomático de los egresados, en este sentido se desarrolló una investigación en la Filial de Ciencias Médicas de Colón con el objetivo de desarrollar la expresión oral en el inglés con fines específicos en el tercer año de la carrera de Medicina. Se (...) emplearon métodos como el análisis de documentos, la observación participante, y los registros anecdóticos. El sistema de actividades aplicado favorece la negociación de significados, toma de riesgos, mayor precisión al expresar ideas, así como el acercamiento del uso del idioma en situaciones reales con lo cual se logra mayor motivación, objetividad del aprendizaje e independencia, al emplear las habilidades lingüísticas para su desempeño profesional. In Cuban medical education, a curriculum in which English is integrated, is designed to fulfill a social mission. Presently, it is a priority to identify strategies that support the idiomatic improvement of graduates. To this end, an investigation was developed in the University of Medical Sciences of Matanzas at Colon Campus with the objective of developing speaking in English for Specific Purposes in the third-year of the medical program of study. Methods such as document analysis, participant observation, and review of anecdotal records were used. The resulting system of activities favors the negotiation of meaning, risk-taking, improved precision to express ideas and the expanded use of English language in real situations. This results in greater motivation, learning objectivity and independence to use language skills for their professional performance. (shrink)

The closure of schools as a result of COVID-19 has been a critical global incident from which to rethink how education works in all our countries. Among the many changes generated by this crisis, all teaching became mediated by digital technologies. This paper intends to analyze the activities carried out during this time through digital technologies and the conceptions of teaching and learning that they reflect. We designed a Likert-type online questionnaire to measure the frequency of teaching activities. It was (...) answered by 1,403 teachers from Spain. The proposed activities varied depending on the learning promoted, the learning outcomes, the type of assessment to which the activities were directed, and the presence of cooperative activities. The major result of this study was that teachers used reproductive activities more frequently than constructive ones. We also found that most activities were those favoring verbal and attitudinal learning. The cooperative activities were the least frequent. Finally, through a cluster analysis, we identified four teaching profiles depending on the frequency and type of digital technologies use: Passive, Active, Reproductive, and Interpretative. The variable that produced the most consistent differences was previous digital technologies use These results show that Information and Communication Technologies uses are reproductive rather than constructive, which impedes effective digital technologies integration into the curriculum so that students gain 21st-century competencies.

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.
