Entrevista con Henri Tajfel

RESUMEN

En la entrevista de David Cohen a Henri Tajfel se repasan algunos aspectos de la vida y de la obra, así como las opiniones del entrevistado en torno a la Psicología Social del momento. El psicólogo polaco recuerda las casualidades y motivaciones que hicieron que se interesase por la Psicología. Reconoce a Bruner y a su escuela, el “New Look”, como la principal influencia y responde a cuestiones relativas a sus primeros años de formación, donde podemos apreciar la influencia que estos años tuvieron en la evolución posterior de su carrera profesional. Tajfel defiende una concepción de la psicología científica basada en el concepto de comprensión (“Verstehen”). El entrevistado mantiene una postura enfrentada tanto a la psicología más positivista como a la de los psicólogos humanistas. Los comentarios de Carmen Huici y David Cohen acerca del autor -uno de los principales responsables de la creación de una identidad de la psicología social europea- introducen la entrevista.     

Think globally: cross-linguistic variation in electrophysiological activity during sentence comprehension

This paper demonstrates systematic cross-linguistic differences in the electrophysiological correlates of conflicts between form and meaning (“semantic reversal anomalies”). These engender P600 effects in English and Dutch (e.g. [Kolk et al., 2003] and [Kuperberg et al., 2003]), but a biphasic N400 - late positivity pattern in German (Schlesewsky and Bornkessel-Schlesewsky, 2009), and monophasic N400 effects in Turkish (Experiment 1) and Mandarin Chinese (Experiment 2). Experiment 3 revealed that, in Icelandic, semantic reversal anomalies show the English pattern with verbs requiring a position-based identification of argument roles, but the German pattern with verbs requiring a case-based identification of argument roles. The overall pattern of results reveals two separate dimensions of cross-linguistic variation: (i) the presence vs. absence of an N400, which we attribute to cross-linguistic differences with regard to the sequence-dependence of the form-to-meaning mapping and (ii) the presence vs. absence of a late positivity, which we interpret as an instance of a categorisation-related late P300, and which is observable when the language under consideration allows for a binary well-formedness categorisation of reversal anomalies. We conclude that, rather than reflecting linguistic domains such as syntax and semantics, the late positivity vs. N400 distinction is better understood in terms of the strategies that serve to optimise the form-to-meaning mapping in a given language.     

Effect of relation availability on the interpretation and access of familiar noun–noun compounds

Two experiments investigate whether relations that link the constituents of compounds during compound formation (e.g., teapot is formed by combining tea and pot using the relation head noun FOR modifier) also influence the processing of familiar compounds. Although there is evidence for the use of such relations in forming compounds, whether such relations affect the processing of familiar compounds is unknown. The data show clear effects of repetition and relational priming for written words on both a sense-nonsense task and a lexical decision task. These results indicate that the relation linking the constituents of familiar compounds is important to their access and use.     

Image Events, the Public Sphere, and Argumentative Practice: The Case of Radical Environmental Groups

Operating from the assumption that a primary dynamic of contemporary public argument involves the use of visual images the authors explore the argumentative possibilities of the `image events' (staged protests designed for media dissemination) employed by radical ecology groups. In contextualizing their discussion, the authors offer an analysis of the contemporary conditions for argumentation by describing the character and operation of public communication, social problem creation, and public opinion formation in a mass-mediated public sphere. The authors argue that image events are a form of postmodern argumentative practice, a kind of oppositional argument that creates social controversy, and animates and widens possibilities for debate. They further suggest that image events are a postmodern form of argument involving acts of protest which deliver images as argumentative fragments. Employing the tools of traditional argument theory the authors describe how images are capable of offering unstated propositions and advancing indirect and incomplete claims in ways that function to block enthymemes and advance alternatives. In concluding, the authors discuss the implications of image events for our understanding of the public sphere and the possibilities for argumentation in a postmodern age.     

Ontology relativized: Reply to Moulines

Ontology is taken by Moulines as supervenient on science: what kinds of things there are is determined by our well-confirmed theories. But the fact is that today, science provides us with a multiplicity of well-confirmed theories, each having its own ontological commitments. The modest, ontological form of reduction advocated by Moulines (this volume) restores hope of putting some ontological order in the “huge chaotic supermarket of science”. In this paper I show that any claim on the amount of order obtained by reduction does not only always remain “temporally qualified” but, worse for the reductionist with a taste for ontological order, that the very notion of orderliness must be relativized to the capacities and interests of knowers.     

Musical structure modulates semantic priming in vocal music

It has been shown that harmonic structure may influence the processing of phonemes whatever the extent of participants' musical expertise [Bigand, E., Tillmann, B., Poulin, B., D'Adamo, D. A., & Madurell, F. (2001). The effect of harmonic context on phoneme monitoring in vocal music. Cognition, 81, B11-B20]. The present study goes a step further by investigating how musical harmony may potentially interfere with the processing of words in vocal music. Eight-chord sung sentences were presented, their last word being either semantically related (La girafe a un tres grand cou, The giraffe has a very long neck) or unrelated to the previous linguistic context (La girafe a un tres grand pied, The giraffe has a very long foot). The target word was sung on a chord that acted either as a referential tonic chord or as a congruent but less referential subdominant chord. Participants performed a lexical decision task on the target word. A significant interaction was observed between semantic and harmonic relatedness suggesting that music modulates semantic priming in vocal music. Following Jones' dynamic attention theory, we argue that music can modulate semantic priming in vocal music, by modifying the allocation of attentional resource necessary for linguistic computation.
