Treinta y cinco años del pensamiento divergente: teoría de la creatividad de Guilford

Resumen

Se analiza cómo ha evolucionado el concepto de pensamiento divergente en la teoría de Guilford. Las primeras definiciones en el año 50 dentro del marco del «Proyecto de Investigación de Aptitudes» postulan una serie de rasgos distintivos para el pensamiento divergente que luego serían objeto de confirmación o refutación a partir de los estudios factoriales.

Dentro del modelo de la «Estructura del Intelecto» de Guilford, se ha ido delimitando la importancia de tales rasgos modificando la definición inicial de algunos, como la sensibilidad a los problemas que, aunque fue concebida como un factor de evaluación, finalmente su definición factorial es de una aptitud de conocimiento; rechazando la importancia de otros para la creatividad, como los factores de análisis y síntesis o, finalmente potenciando otros que inicialmente tuvieron menor consideración, como las aptitudes para las transformaciones que, son consideradas por Guilford como una contribución tan importante para la creatividad como la producción divergente.     

Morality and behavioural regulation in groups: A social identity approach

In recent years social psychologists have displayed a growing interest in examining morality—what people consider right and wrong. The majority of work in this area has addressed this either in terms of individual-level processes (relating to moral decision making or interpersonal impression formation) or as a way to explain intergroup relations (perceived fairness of status differences, responses to group-level moral transgressions). We complement this work by examining how moral standards and moral judgements play a role in the regulation of individual behaviour within groups and social systems. In doing this we take into account processes of social identification and self-categorisation, as these help us to understand how adherence to moral standards may be functional as a way to improve group-level conceptions of self. We review a recent research programme in which we have investigated the importance of morality for group-based identities and intra-group behavioural regulation. This reveals convergent evidence of the centrality of moral judgements for people’s conceptions of the groups they belong to, and demonstrates the importance of group-specific moral norms in identifying behaviours that contribute to their identity as group members.     

A WAR OF MEMORIES

This article discusses Renzo De Felice’s Intervista sul Fascismo, published in 1975, as representative of a particular memory in the Italy of that time and considers its influence and impact on the subsequent historiographical and political discourse in Italy about fascism, the War of Liberation, and the Shoah. The starting point is the existence of many competing memories that battle with one another for supremacy. The very diversity of these memories – silent, always contemporary but different – sends one back to the agent par excellence of memory formation: politics. Because the memories of fascism, the war, the Resistance, and the Shoah represent essentially political structures, they are fated to vary in response to the definitions of the diverse identity groups that are dominant in a society in the struggle for the emergence of one memory at the expense of the others.     

Meditation,Health and Scientific Investigations: Review of the Literature

A growing number of people are seeking health recovery treatments with a holistic approach to the human being. Meditation is a mental training capable of producing connection between the mind, body and spirit. Its practice helps people to achieve balance, relaxation and self-control, in addition to the development of consciousness. At present, meditation is classified as a complementary and integrative technique in the area of health. The purpose of this review of the literature was to describe what meditation is, its practices and effects on health, demonstrated by consistent scientific investigations. Recently, the advances in researches with meditation, the discovery of its potential as an instrument of self-regulation of the human body and its benefits to health have shown that it is a consistent alternative therapy when associated with conventional medical treatments.     

Age-of-acquisition norms for a set of 1,749 Portuguese words

Age of acquisition (AoA) is an important psycholinguistic variable that affects the speed and accuracy of lexical processing in tasks such as word naming, picture naming, and lexical decision. In the present work, we collected AoA ratings for 1,749 Portuguese words (nouns, verbs, adjectives, and adverbs), using a 9-point scale that was first proposed by Carroll and White (1973). We analyzed the relation between AoA ratings and other psycholinguistic variables (length measures, neighborhood density, written-word frequency, familiarity, imageability, and concreteness), and we assessed reliability by correlating our ratings with those from other databases presented for Portuguese, English, Spanish, and Italian. The full database can be downloaded from http://brm.psychonomic-journals.org/content/supplemental.     

How primates acquire their gestures: evaluating current theories and evidence

Animal Cognition - Mechanisms underlying gesture acquisition in primates are largely unstudied, yet heavily debated. While some studies suggest that gestural repertoires are largely innate, others...     

Visual attention in adolescents: Facilitating effects of sport expertise and acute physical exercise

ObjectivesThis study investigated visual attention of adolescent orienteers and physically active adolescents non-practising orienteering both at rest and under acute sub-maximal exercise. It was verified whether the practice of orienteering facilitates the development of visual attentional abilities and whether orienteers, who are used to simultaneously handle physiological and cognitive-attentional loads, may better profit than non-orienteers from the beneficial effects of sub-maximal physical load on processing speed.MethodsBoth the focusing of attention at foveal and parafoveal locations and the orienting of attention at peripheral locations were investigated. In two discriminative reaction time (RT) experiments, a cue of varying size was presented centrally or peripherally and followed by a compound stimulus with local and global target features. The stimulus-onset asynchrony (SOA) varied between a short and a long interval.ResultsIn both experiments, adolescent orienteers and non-practisers showed different patterns of attentional effects. Adolescent orienteers were more similar to young adults in the attentional performance, being better able than non-practisers to perform complex attentional operations involving the intentional zooming of attention in the central visual field and the orienting of the attentional focus in the peripheral visual field. Also, both orienteers and non-orienteers speeded up their performance during exercise, but this facilitation effect was more pronounced for orienteers, who are probably skilled in directing the available resources to task demands.ConclusionsOur results suggest that cognitive expertise represents a key factor in sports that accelerates the development of visual attention and enhances the facilitating effects of physical exercise on attentional performance.     

The Perceived Advantages and Disadvantages of Presymptomatic Testing for Machado-Joseph Disease: Development of a New Self-Response Inventory

This study describes the construction of a self-response inventory to evaluate the perception of advantages and disadvantages of the Machado-Joseph disease presymptomatic testing, in 44 individuals at-risk for this disease. The results showed that the reliability of this inventory was satisfactory. Factor analysis revealed a bidimensional structure: perceived advantages (pros) and perceived disadvantages (cons) of presymptomatic testing. Social desirability was found unrelated to the total scores of our inventory. Additional correlation studies, with other scales, confirmed the convergent validity of the instrument. These results suggest adequate construct validity. This inventory thus seems to be a proper instrument to assess expectations involved in the decision-making process of Machado-Joseph disease presymptomatic testing.
