La metáfora conceptual es utilizada con frecuencia como estrategia divulgativa para acercar el conocimiento especializado a un público lego, pero su eficacia comunicativa para la transmisión de contenido especializado no se ha comprobado empíricamente. El objetivo de este trabajo es explorar la incidencia de las metáforas en la comprensión de textos escritos divulgativos del área de Biología. Se diseñó una prueba de comprensión lectora con 4 fragmentos de textos de divulgación con expresiones metafóricas y sin expresiones metafóricas, acompañados de 16 (...) preguntas de selección múltiple. La prueba se aplicó a 30 estudiantes de segundo año medio de un colegio chileno, y se complementó con una entrevista semiestructurada a tres de los estudiantes. Los resultados obtenidos demostraron que, a nivel local, las metáforas estructurales de una correspondencia y las de imagen posibilitan una mejor comprensión. Sin embargo, a nivel global, no se evidenció un mejor desempeño en la lectura de textos con presencia de expresiones metafóricas. Estos hallazgos permiten caracterizar el nivel de eficacia de la metáfora conceptual en el proceso de comprensión de contenido especializado, así como informar sobre el diseño de textos divulgativos con propósitos didácticos.

Este artículo presenta un estudio sobre la terminología empleada para referirse al período histórico del Golpe y Dictadura Militar en los textos escolares de enseñanza media de historia de Chile. Los términos representan los conceptos especializados de una disciplina y reflejan la conceptualización particular de la realidad por parte de una determinada comunidad disciplinar en un contexto socio-temporal. Por ello, influyen en la manera en que el receptor accede al conocimiento. Este estudio tuvo por objetivo describir el punto de vista (...) sobre el Golpe y la Dictadura Militar transmitido a través de la terminología en los manuales de historia chilenos, y determinar si esta ha evolucionado con el paso de los años. Para ello, se analizaron las variantes terminológicas de los conceptos principales que configuran el periodo histórico en la unidad didáctica sobre el tema en textos escolares de 2º y 3º Medio, licitados por el Mineduc entre el 2002 y 2014. Luego, a partir del análisis de la información conceptual reflejada en cada variante y el nivel de abstracción de la categoría seleccionada, se interpretó si las variantes reflejaban un punto de vista negativo, neutro o positivo del concepto. Los resultados demostraron que las denominaciones son relativamente estables a lo largo de los años y transmiten puntos de vista mayormente neutros. Estos resultados contrastan con la perspectiva pluralista de los hechos que promulga el Mineduc en sus bases curriculares. (shrink)

Dentre os problemas tradicionais da Epistemologia, uma das controvérsiasmais persistentes é a questão da inserção versus isenção de valores naciência. Filiando-se a uma longa tradição crítica, o filósofo Hugh Laceydesenvolve um exame contundente acerca dos fundamentos da ciência emsua interação com a sociedade, questionando a noção tradicional deneutralidade científica. Pretendemos nesse trabalho estender a crítica deLacey às ciências sociais, e especificamente à Economia. Argumentamosque a ortodoxia da ciência econômica moderna , atravésda incorporação do paradigma mecanicista da física clássica, bem comode (...) todo instrumental analítico das estratégias materialistas, não representaum tipo de compreensão neutra dos fenômenos econômicos, mas sim umaparticularmente notável manifestação dos valores predominantes nessasociedade , da qual faz parte.Assim, procuramos mostrar que, também no âmbito social, a preeminênciados aspectos nomológicos e quantitativos da realidade na formulação dasteorias econômicas de tradição neoclássica espelha valores sociais altamenteestimados nas sociedades modernas.Among the traditional problems in Epistemology, one of the most persistentcontroversies is the question of value insertion versus value exemption inscience. The philosopher Hugh Lacey, in consonance with a long criticaltradition, advances a sharp examination of the foundations of science andits interaction with society, questioning the traditional notion of scientificneutrality. In this essay we intend to extend Lacey’s criticism to the socialsciences – specifically to Economics. We argue that modern economicsorthodoxy , by the adoption of the mechanicalparadigm of classical physics and all the analytical instruments of thematerialist strategies, does not represent a type of neutral understandingof the economic phenomena, but instead, a particularly considerablemanifestation of the predominant values of the society of which it is a part. So, we intend to showthat also in the social scope, the favoring of the nomological and quantitativeaspects of reality mirrors social values highly regarded in modern societies. (shrink)

A pragmatic account of referential communication is developed which presents an alternative to traditional Gricean accounts by focusing on cooperativeness and efficiency, rather than informativity. The results of four language‐production experiments support the view that speakers can be cooperative when producing redundant adjectives, doing so more often when color modification could facilitate the listener's search for the referent in the visual display (Experiment 1a). By contrast, when the listener knew which shape was the target, speakers did not produce redundant color (...) adjectives (Experiment 1b). English speakers used redundant color adjectives more often than Spanish speakers, suggesting that speakers are sensitive to the differential efficiency of prenominal and postnominal modification (Experiment 2). Speakers were also cooperative when using redundant size adjectives (Experiment 3). Overall, these results show how discriminability affects a speaker's choice of referential expression above and beyond considerations of informativity, supporting the view that redundant speakers can be cooperative.

In the last 30 years, the key issue in developmental Theory of Mind has been if and when children are capable of representing false beliefs. Moving away from this research question, the aim of this study was to investigate the role of attentional processes in false-belief tasks. We focused on the design of the test phase and investigated two factors that may be critical for 3-year-old children’s success: the form of the wh-question and the salience of the target object. The (...) results of two experiments confirmed that 3-year olds are able to explicitly choose the correct answer in a false-belief task provided that they are allowed to focus on the protagonist throughout the task. The salience of the target object, however, was a critical factor in the design of the test phase, as increasing it had a negative effect on children’s performance. These results suggest that the experimental record of the last 30 years may be skewed since standard false-belief tasks do not control for the relative salience of the wrong response, potentially hindering the performance of children under 4. We conclude that a careful investigation of performance factors in false-belief tasks has the potential to reveal deep insights into the development of Theory of Mind skills, even if not directly focused on children’s representation of beliefs.

Language and Theory of Mind come together in communication, but their relationship has been intensely contested. I hypothesize that pragmatic markers connect language and Theory of Mind and enable their co-development and co-evolution through a positive feedback loop, whereby the development of one skill boosts the development of the other. I propose to test this hypothesis by investigating two types of pragmatic markers: demonstratives and articles. Pragmatic markers are closed-class words that encode non-representational information that is unavailable to consciousness, but (...) accessed automatically in processing. These markers have been associated with implicit Theory of Mind because they are used to establish joint attention and mark shared knowledge. Here I develop a theoretical account of how joint attention is the basis for children’s later tracking of common ground. The developmental path from joint attention to common ground parallels language change, with demonstrative forms giving rise to definite articles. This parallel opens the possibility of modelling the emergence of Theory of Mind in human development in tandem with its routinization across language communities and generations of speakers. I therefore propose that, in order to understand the relationship between language and Theory of Mind, we should study pragmatics at three parallel timescales: during language acquisition, language use, and language change.

In standard Relevance Theory, hyperbole and metaphor are categorized together as loose uses of language, on a continuum with approximations, category extensions and other cases of loosening/broadening of meaning. Specifically, it is claimed that there are no interesting differences between hyperbolic and metaphorical uses. In recent work, we have set out to provide a more fine-grained articulation of the similarities and differences between hyperbolic and metaphorical uses and their relation to literal uses. We have defended the view that hyperbolic use (...) involves a shift of magnitude along a dimension which is intrinsic to the encoded meaning of the hyperbole vehicle, while metaphor involves a multi-dimensional qualitative shift away from the encoded meaning of the metaphor vehicle. In this article, we present three experiments designed to test the predictions of this analysis, using a variety of tasks (paraph. (shrink)

It has been generally assumed in the Theory of Mind literature of the past 30 years that young children fail standard false-belief tasks because they attribute their own knowledge to the protagonist. Contrary to the traditional view, we have recently proposed that the children's bias is task induced. This alternative view was supported by studies showing that 3 year olds are able to pass a false-belief task that allows them to focus on the protagonist, without drawing their attention to the (...) target object in the test phase. For a more accurate comparison of these two accounts, the present study tested the true-belief default with adults. Four experiments measuring eye movements and response inhibition revealed that adults do not have an automatic tendency to respond to the false-belief question according to their own knowledge and the true-belief response need not be inhibited in order to correctly predict the protagonist's actions. The positive results observed in the control conditions confirm the accuracy of the various measures used. I conclude that the results of this study undermine the true-belief default view and those models that posit mechanisms of response inhibition in false-belief reasoning. Alternatively, the present study with adults and recent studies with children suggest that participants' focus of attention in false-belief tasks may be key to their performance. (shrink)

The present study aims to investigate the extent to which the process of lexical interpretation is context dependent. It has been uncontroversially agreed in psycholinguistics that interpretation is always affected by sentential context. The major debate in lexical processing research has revolved around the question of whether initial semantic activation is context sensitive or rather exhaustive, that is, whether the effect of context occurs before or only after the information associated to a concept has been accessed from the mental lexicon. (...) However, within post-lexical access processes, the question of whether the selection of a word's meaning components is guided exclusively by contextual relevance, or whether certain meaning components might be selected context independently, has not been such an important focus of research. I have investigated this question in the two experiments reported in this paper and, moreover, have analysed the role that context-independent information in concepts might play in word interpretation. This analysis differs from previous studies on lexical processing in that it places experimental work in the context of a theoretical model of lexical pragmatics. (shrink)

La influencia de la obra y doctrina de Francisco Suárez en la conformación del pensamiento moderno ha sido ampliamente estudiada en áreas como la filosofía política y del derecho, la metafísica o la epistemología. Sin embargo, la filosofía moral de Suárez, en concreto aquella que, como él mismo explica, habrá de servir de base a sus tratados de teología moral, está todavía por analizar. El objetivo de este trabajo es traer a luz algunos aspectos de la teoría suareciana sobre la (...) causalidad final en los agentes libres, confrontando su doctrina sobre la causalidad del fin en dos comentarios, escritos en distintos períodos, a las cuestiones I-IIae de la Suma de Teología de Tomás de Aquino: el manuscrito inédito De beatitudine y el tratado De ultimo fine hominis, publicado por Baltasar Álvares. La cuestión aquí analizada —qué significa actuar por un fin— se asume como un instrumento heurístico para dar a conocer sea estas dos fuentes estudiadas, sea el interés filosófico de las doctrinas de Suárez a respecto de la causalidad final. Las conclusiones apuntan a los siguientes aspectos: i) la proximidad, aun con dudas, de Suárez a la doctrina tomista de la causalidad del fin, en el comentario de 1579; ii) la asunción parcial de la doctrina tomista en cuanto a la función del intelecto en el actuar libre, y la afirmación de que el locus finis es la voluntad, en el comentario de 1628. Trabajando con estos matices hemos querido establecer algunos puntales de encuentro que permitan hacer visibles los puentes que emergen entre una tradición escolástica que enfrenta una nueva imagen del hombre, y la filosofía moral inmediatamente posterior que despojando aquella de su fundamento teológico, avanza con paso firme hacia la modernidad.

Categorisation models of metaphor interpretation are based on the premiss that categorisation statements and comparison statements are fundamentally different types of assertion. Against this assumption, we argue that the difference is merely a quantitative one: ‘x is a y’ unilaterally entails ‘x is like a y’, and therefore the latter is merely weaker than the former. Moreover, if ‘x is like a y’ licenses the inference that x is not a y, then that inference is a scalar implicature. We defend (...) these claims partly on theoretical grounds and partly on the basis of experimental evidence. A suite of experiments indicates both that ‘x is a y’ unilaterally entails that x is like a y, and that in several respects the non-y inference behaves exactly as one should expect from a scalar implicature. We discuss the implications of our view of categorisation and comparison statements for categorisation models of metaphor interpretation. (shrink)

Gricean pragmatics has often been criticised for being implausible from a psychological point of view. This line of criticism is never backed up by empirical evidence, but more importantly, it ignores the fact that Grice never meant to advance a processing theory, in the first place. Taking our lead from Marr, we distinguish between two levels of explanation: at the W-level, we are concerned with what agents do and why; at the H-level, we ask how agents do whatever it is (...) they do. Whereas pragmatics is pitched at the W-level, processing theories are at the H-level. This is not to say that pragmatics has no implications for psychology at all, but it is to say that its implications are less direct than is often supposed. (shrink)

As companies increasingly communicate CSR initiatives through social media, viral message propagation has become a crucial prerequisite for CSR success. Evidence from two experimental studies, one based on a national representative online sample, shows that social media peers’ endorsement of a CSR message in terms of number of shares, likes and positive replies contributes to an individual’s intention to share it on the social network and thereby participate in message propagation, and that this process can be explained by normative influences (...) exerted by the social media community through the activation of injunctive and descriptive norms, as well as social identity motives. Findings further confirmed that the norm-activating effects of social media endorsement are moderated by the empowering qualities of the CSR message, the sharing source of the message by affecting CSR credibility, and the recipient’s interdependent self-construal. Corporate communication managers are advised to achieve a high degree of initial social media endorsement of their CSR message, for recipients of the message to perceive social pressure motivating message sharing with their social media peers.

An experimental study was designed to analyze the effect of school-based training in self-regulation learning strategies on academic performance. Class-level variables were considered and the effects of the intervention were measured at the end of the intervention and 3 months later. A sample of 761 students from 3rd and 4th grades, from 14 schools, participated in the study. Data were analyzed using three-level analysis with within-student measurements at level 1, between-students within-classes at level 2, and between-classes at level 3. Data (...) showed a positive effect of the intervention on student performance, both at post-test and at follow-up considering the four school subjects together. However, the effect was significant just at follow-up when subjects were considered separately. Student performance was significantly related to the students’ variables and the context. Finally, students’ gender and level of reading comprehension, as well as the teacher’s gender, were found to moderate the effect of the intervention on students’ academic performance. Two conclusions were highlighted: first, data emphasize the importance of considering time while conducting intervention studies. Second, more teaching experience does not necessarily translate into improvements in the quality of students’ instruction. (shrink)

La reciente reelección de Cristina Fernández en la Argentina con una mayoría abrumadora y las ceremonias y memorial inaugurados en honor del ex- presidente Néstor Kirchner a poco más de un año de su muerte vuelven más necesaria la revisión del origen del kirchnerismo para comprender su relación con la política democrática y el populismo. Por suerte contamos con un buen libro para iniciar esta tarea. Me refiero a En el Nombre del Pueblo, un esfuerzo mancomunado de cinco jóvenes investigadoras...

In this essay I address the question, “What is the subject matter of phenomenological research?” I argue that in spite of the increasing popularity of phenomenology, the answers to this question have been brief and cursory. As a result, contemporary phenomenologists lack a clear framework within which to articulate the aims and results of their research, and cannot easily engage each other in constructive and critical discourse. Examining the literature on phenomenology’s identity, I show how the question of phenomenology’s subject (...) matter has been systematically neglected. It has been overshadowed by an unending concern with phenomenology’s methodological identity. However, an examination of recent contributions to this literature reveals that a concern with articulating phenomenology’s subject matter has gradually increased, although such articulations remain preliminary. In light of this, I delineate, define, and illustrate three layers of phenomenological research, which I term “existentials,” “modes,” and “prejudices.” While the delineation of these layers is drawn primarily from classical phenomenological texts, they are defined and illustrated through the use of more contemporary literature. Following the articulation of this subject matter, I briefly consider some of the debates—both foundational and applied—that can be facilitated by the adoption of this framework. (shrink)

This article provides an overview of some prominent aspects of intellectual history as practiced today in Latin America, especially regarding conceptual history. It delves into the way this methodology arrived to the region not long ago and discusses the way some of its practitioners combine it with the history of political languages, often ignoring the profound differences between both approaches. Therefore, the text stresses some of the most significant contrasts between them. In its last part, the article is critical of (...) the purported “globality” of global intellectual history, an issue that is inextricably linked with the pervasive use of the English language in the field. Throughout, the text poses several of the challenges that lie ahead for intellectual history in Latin America. (shrink)
