El estudio del significado mediante pruebas de sustitución de palabras

Resumen

Se presenta un método nuevo de estudio semántico del lenguaje: la técnica de sustitución de palabras (TSP), así como algunas pruebas concretas para aplicación de dicha técnica general. Las pruebas consisten en repertorios de frases donde figura la palabra por investigar en cada caso, palabra que los sujetos que realizan la prueba han de sustituir por alguna o algunas otras, tratando de conservar el sentido de la frase. Aunque constituye una técnica general de investigaión semántica, destacan sus ventajas en el estudio de ciertos lenguajes: político, ético, religioso y filosófico.     

Elementos cognitivos y otros en el sistema de la personalidad

Resumen

Se señalan las raíces y antecedentes históricos para el estudio de los componentes cognitivos del sistema de la personalidad en la triple área de una psicología diferencial de los estilos cognitivos y otras diferencias cognitivas entre personas, de la psicología del concepto de sí mismo, y de las interpretaciones cognitivas de procesos adaptativos y dinámicos. A continuación, se exponen los nuevos temas que, integrados a los anteriores, pueden configurar hoy una psicología cognitiva de la personalidad. Pero, sobre la base de la multiplicidad de fenómenos y estructuras comprendidas en el sistema de la personalidad, se rechaza la pretensión de que categorías puramente cognitivas puedan, por si solas, dar razón de dicho sistema.     

Repercusión de la autoimagen en el diagnóstico de la capacidad de formar imágenes mentales

Resumen

Desde 1909 hasta la actualidad se han construido y utilizado mucho los cuestionarios para medir la capacidad de los sujetos para formar imágenes mentales; sin embargo, han sido muy discutidos, fundamentalmente porque las autopuntuaciones de imagen están contaminadas por las expectativas sociales.

Nosotros estudiamos la relación de la autoestima y la autoimagen con la viveza subjetiva de imagen visual. Presentamos a 93 estudiantes de Formación Profesional un test objetivo de imagen, un test subjetivo de imagen, una medida de autoestima y una de autoimagen. Obtuvimos correlaciones significativas entre la autoestima y la medida subjetiva de imagen, y entre la autoimagen y la medida subjetiva de imagen; sin embargo, la autoestima y la autoimagen no correlacionaron significativamente con un test objetivo de imagen.

Abstract

Since the concept of imaginative elaboration of body functioning, which is essential to Winnicott's idea of psyche-soma, has rarely been investigated up to now, this article sets out to do this and tries to pursue the meaning and articulation of that concept in the corpus of Winnicott's theory. In this way, it contributes to bringing the body to the core of psychoanalytical theory.     

The study of organizational behaviour in family business

Family businesses (FBs)—enterprises that are significantly influenced by family members and kinship ties—are ubiquitous and play a crucial role across all world economies. Because of the embeddedness of family and business systems in FB, these organizational forms are theoretically distinct from their non-family counterparts. Curiously, FBs have been largely overlooked in the organizational behaviour (OB) literature. The limited available research at the interface of OB and FB highlights the importance of FB as a unique context to advance OB theories, and of OB as a promising discipline to increase our understanding of FB. In a selective review of literature focused on the four topics of values and goals, leadership and power, trust and justice, and conflict, we discuss how insights from the general theory of communal and exchange relationships open exciting avenues for research at the FB-OB interface. Rich fruits of intellectual harvest await scholars who focus on behavioural research in FB.     

Dissociative Experiences and Creativity in Fine Arts Students

Studies on creative personality have revealed that the relationship between personality and creativity remains unclear, and various types of creative thinking have been have been associated with various personality traits. To assess the influence of dissociative experiences on creativity in the context of fine arts education, in which the creative process plays a key role, a sample of fine arts students received a test of creative potential and the dissociative experiences test. The results revealed significant differences in creativity (creative imagination and creative experiences) between students scoring high or low in the number of dissociative experiences. High dissociative experiences scores were associated to high scores in creative imagination and creative experiences, and low scores in dissociative experiences were inversely related to creative imagination and creative experiences. Further studies are required to corroborate these findings.     

Gender Differences and Cognitive Correlates of Mathematical Skills in School-Aged Children

Published information concerning the influence of gender on mathematical ability tests has been controversial. The present study examines the performance of school-aged boys and girls from two age groups on several mathematical tasks and analyzes the predictive value of a verbal fluency test and a spatial test on those mathematical tasks. More specifically, our research attempts to answer the following two questions: (1) Are gender differences in mathematical test performance among children interrelated with age and (2) do verbal and spatial nonmathematical tests mediate gender effects on mathematical test performance? Two hundred and seventy-eight 7- to 10-year-old children and 248 13- to 16-year-olds were selected from schools in Colombia and Mexico (231 boys and 295 girls). The age effect was found to be significant for all measures, with scores improving with age. Results showed that boys and girls in both age groups scored similarly in most subtests, but that differences emerged in the performance of mental mathematical operations and in resolving arithmetical problems. In the latter – but not in mental math – older boys outperformed older girls, whereas no gender differences were observed in the younger groups. After controlling for age, it was found that the spatial test was, indeed, a significant mediator of gender effects, while the verbal task was not.     

Some views are better than others: evidence for a visual bias in object views self‐generated by toddlers

How objects are held determines how they are seen, and may thereby play an important developmental role in building visual object representations. Previous research suggests that toddlers, like adults, show themselves a disproportionate number of planar object views – that is, views in which the objects' axes of elongation are perpendicular or parallel to the line of sight. Here, three experiments address three explanations of this bias: (1) that the locations of interesting features of objects determine how they are held and thus how they are viewed; (2) that ease of holding determines object views; and (3) that there is a visual bias for planar views that exists independently of holding and of interesting surface properties. Children 18 to 24 months of age manually and visually explored novel objects (1) with interesting features centered in planar or ¾ views; (2) positioned inside Plexiglas boxes so that holding biased either planar or non‐planar views; and (3) positioned inside Plexiglas spheres, so that no object properties directly influenced holding. Results indicate a visual bias for planar views that is influenced by interesting surface properties and ease of holding, but that continues to exist even when these factors push for alternative views.     

Gender differences in cognitive development

The potential effect of gender on intellectual abilities remains controversial. The purpose of this research was to analyze gender differences in cognitive test performance among children from continuous age groups. For this purpose, the normative data from 7 domains of the newly developed neuropsychological test battery, the Evaluación Neuropsicológica Infantil [Child Neuropsychological Assessment] (Matute, Rosselli, Ardila, & Ostrosky-Solis, 2007), were analyzed. The sample included 788 monolingual children (350 boys, 438 girls) ages 5 to 16 years from Mexico and Colombia. Gender differences were observed in oral language (language expression and language comprehension), spatial abilities (recognition of pictures seen from different angles), and visual (Object Integration Test) and tactile perceptual tasks, with boys outperforming girls in most cases, except for the tactile tasks. Gender accounted for only a very small percentage of the variance (1%-3%). Gender x Age interactions were observed for the tactile tasks only. It was concluded that gender differences during cognitive development are minimal, appear in only a small number of tests, and account for only a low percentage of the score variance.     

Generalization decrement and not overshadowing by associative competition among pairs of landmarks in a navigation task

When they are trained in a Morris water maze to find a hidden platform, whose location is defined by a number of equally spaced visual landmarks round the circumference of the pool, rats are equally able to find the platform when tested with any two of the landmarks (Prados, & Trobalon, 1998; Rodrigo, Chamizo, McLaren, & Mackintosh, 1997). This suggests that none of the landmarks was completely overshadowed by any of the others. In Experiment 1 one pair of groups was trained with four equally salient visual landmarks spaced at equal intervals around the edge of the pool, while a second pair was trained with two landmarks only, either relatively close to or far from the hidden platform. After extensive training, both male and female rats showed a reciprocal overshadowing effect: on a test with two landmarks only (either close to or far from the platform), rats trained with four landmarks spent less time in the platform quadrant than those trained with only two. Experiment 2 showed that animals trained with two landmarks and then tested with four also performed worse on test than those trained and tested with two landmarks only. This suggests that generalization decrement, rather than associative competition, provides a sufficient explanation for the overshadowing observed in Experiment 1. Experiment 3 provided a within-experiment replication of the results of Experiments 1 and 2. Finally, Experiment 4 showed that rats trained with a configuration of two landmarks learn their identity.
