Estructura morfológica y recuperación léxica

Resumen

El objetivo principal de esta investigación es el de contribuir a un mayor conocimiento del papel que desempeña la estructura morfológica de las palabras en la organización del léxico interno y, por consiguiente, en las estrategias que emplean los sujetos para acceder a la representación mental de las palabras. Más en concreto, se trata de ver cuál es la relación existente entre la representación de la forma base de una palabra (por ej., flor) y la de formas derivadas de la misma (por ej., florero, florecer, florido) de cara a una posible simplificación del inventario mental de entradas léxicas.

Se han realizado tres experimentos, basados en una tarea de decisión léxica y en la utilización de la técnica de «priming» o presentación previa de un supuesto elemento facilitador del reconocimiento de cada estímulo. Se midió la latencia de respuesta para clasificar los estímulos como palabras o no-palabras del idioma. Los dos primeros experimentos se efectuaron bajo la modalidad visual de reconocimiento y el tercero, bajo la modalidad auditiva. En todos los casos, las comparaciones relevantes se establecen entre los TRs correspondientes a una misma palabra en condiciones experimentales diferentes: según vaya precedida por sí misma, o por una relacionada morfológicamente, o cuando no vaya precedida ni por sí misma ni por otra relacionada (condición de control).

Los resultados obtenidos bajo las dos modalidades perceptivas son coincidentes y ponen de manifiesto que: 1) se da un efecto de facilitación en el reconocimiento, tanto al presentar una palabra precedida por sí misma (repetición) como al presentarla precedida por otra relacionada morfológicamente; 2) el efecto de facilitación por repetición es significativamente superior al de facilitación por relación morfológica; y 3) dentro de este último no aparecen diferencias significativas entre la facilitación de la forma base por la derivada y la de ésta por aquélla.

Estos resultados se interpretan a la luz de los distintos modelos propuestos acerca de la representación léxica. Sin que sean cruciales para decidirse por uno de ellos en contra de los otros, sí que parecen apoyar la existencia de un código de representación abstracto que aglutina familias de palabras relacionadas morfológicamente en torno a una misma entrada léxica. En cualquier caso, y aun suponiendo que hubiera entradas léxicas distintas para cada forma particular, sería preciso postular algún mecanismo adicional que diera cuenta del papel que desempeña la información morfológica en la organización general del léxico interno.     

Procesos cognitivos: una introducción a la psicología informacional

RESUMEN

En el presente artículo se defiende la idea de que los mecanismos que organizan la conducta tienen una importancia tan grande como la energía misma en la determinación de aquélla, que estos mecanismos son por tanto seriales como de control y que los estadios de procesamiento de información deben corresponder en su naturaleza a estos mecanismos. Se centra la exposición en el tema de la información desde dos contextos diferentes, que se intentan relacionar: primero, el contexto de la comunicación humana; segundo, el contexto de la cibernética y la teoría de sistemas, sustentado en la proposición de algunos autores de la teoría de sistemas constituye una parte de la cibernética y no al revés.     

Entrevista a Urie Bronfenbrenner

RESUMEN

Urie Bronfenbrenner comienza repasando su biografía y explicando la influencia de figuras como Kurt Lewin, Tolman o sus propios padres en su formación científica. A continuación se ocupa de los problemas metodológicos de la investigación en Psicología, sus estudios incorporando el modelo “persona-proceso-contexto” o los trabajos de laboratorio, centrándose en diversas reflexiones en torno a la perspectiva ecológica y la consideración del ambiente. Además el autor adelanta algunos conceptos de su último trabajo todavía inédito, como el factor tiempo o la relevancia del sistema de creencias para comprender el desarrollo. Finalmente aborda su vinculación a programas de intervención social y comunitarios y aporta algunas ideas acerca del futuro de la psicología europea y española.     

Only your eyes tell me what you like: Exploring the liking effect induced by other's gaze

Our preferences are sensitive to social influences. For instance, we like more the objects that are looked-at by others than non-looked-at objects. Here, we explored this liking effect, using a modified paradigm of attention cueing by gaze. First, we investigated if the liking effect induced by gaze relied on motoric representations of the target object by testing if the liking effect could be observed for non-manipulable (alphanumeric characters) as well as for manipulable items (common tools). We found a significant liking effect for the alphanumeric items. Second, we tested if another type of powerful social cue could also induce a liking effect. We used an equivalent paradigm but with pointing hands instead of gaze cues. Pointing hands elicited a robust attention-orienting effect, but they did not induce any significant liking effect. This study extends previous findings and reinforces the view of eye gaze as a special cue in human interactions.     

Lack of habituation to shocking words: The attentional bias to their spatial origin is context free

Following a suggestion made by Aquino and Arnell (2007), we assumed that the processing of emotional words is influenced by their context of presentation. Supporting this idea, previous studies using the emotional Stroop task in its visual or auditory variant revealed different results depending on the mixed versus blocked presentation of the stimuli (Bertels, Kolinsky, Pietrons, & Morais, 2011; Richards, French, Johnson, Naparstek, & Williams, 1992). In the present study, we investigated the impact of these presentation designs on the occurrence of spatial attentional biases in a modified version of the beep-probe task (Bertels, Kolinsky, & Morais, 2010). Attentional vigilance to taboo words as well as non-spatial slowing effects of these words were observed whatever the mixed or blocked design, whereas attentional vigilance to positive words was only observed in the mixed design. Together with the results from our previous study (Bertels et al., 2010), the present data support the reliability of the effects of shocking stimuli, while vigilance to positive words would only be observed in a threatening context.     

The clinical revolution of the ‘wise baby’

In an historical context focused on a close examination of the complex relationship between Freud and Ferenczi, the author shows Ferenczi's contribution to the evolution of psychoanalysis. He describes how his ideas and his therapeutic sensitivity anticipated modern clinical thought (for example, Winnicott and Bion), especially the understanding of borderline and narcissistic pathology. The paper considers the following topics: transference and countertransference; early affectivity; the different psychic trauma; phenomena connected with dissociation; the healing factor of the analysis.     

Sartre on the Ontological Need for God

Adherents to the relatively new discipline of neurotheology profess that religious faith has a brain neural substrate, with structural, functional, and genetic elements that “hardwire” us to believe in God. It is argued here that a better way to approach the question of why people believe in a transcendent being would be to interrogate the structure of human being, with the intention of uncovering the meanings that underlie the phenomenon of faith. Jean-Paul Sartre may have already provided a necessary and sufficient explanation for this phenomenon. We are, he concluded, ontologically inclined to identify with a supreme being whose essence and existence transcend the limits of our own finite being. It is one thing to arrive at such a conclusion intuitively, but altogether something else to demonstrate, as Sartre does, how this conclusion follows from the structure of human being itself.     

The growth hypothesis and self‐actualization: An existential alternative

Abstract

Examining the process of becoming from an existential perspective, we describe the existence of the self in non‐biological terms as a product of its own intentionality. In this context, there is no need to postulate a growth hypothesis in order to (1) to describe a person as a process of becoming, and (2) to explain self‐actualization. While the process of becoming is a static process, self‐actualization is a dynamic process. In the first case, the self deterministically and naively merely becomes. In the second, case, the process results from becoming the object of personal choices, whereby we become authentic. While the self is “a being in the process of mere becoming,” self‐actualization is “a being in the process of authentic becoming.” In this view, humanistic psychotherapy aims at making the self's mere becoming an authentic process. Existential crisis, in particular confrontation with death, is often the transformational medium.     

Performance in Autobiographical Memory of Older Adults with Depression Symptoms

The aim of this study was to compare the performance in the Autobiographical Memory Test in older adults with high scores on depression symptoms (HDS) compared with a matched group with low scores on depression symptoms (LDS) according to the clinical cut‐off of the Centre for Epidemiological Studies Depression Scale. Participants were asked to generate specific autobiographical memories in response to a series of positive and negative cue words. Latencies of responses for each item were also scored. LDS participants showed a higher proportion of specific memories than HDS participants. Latencies of responses to positive and negative cues were greater for HDS than LDS. Specific autobiographical memory was positively associated with Life Satisfaction. Cognitive emotional changes in the function of memory with age are suggested as a possible explanation for the findings. Copyright © 2012 John Wiley & Sons, Ltd.     

The Use of Priority Information in Performance Feedback

To provide the most value to an organization, individuals must focus efforts on those outputs that have maximum value to the organization. However, the realities of the workplace are that information about performance and how individuals can add value to an organization is complex; that is, determining which activities to focus on is a fairly complex task because such information is nonlinear, whereby the importance of a certain activity may change depending on the level of performance at any given time. This article empirically examines whether providing complex, nonlinear feedback that reflects the complexities of the real world will result in a change in work outputs that reflect these nonlinearities. This article assesses whether employees can and do use complex feedback that reflects the complexity of the real world in the intended ways. In addition, this article examines whether individuals use feedback that includes priority information beyond feedback that reports on simple relative importance. Data were analyzed from 9 work units for time periods averaging a little over a year. Results indicate that, as predicted, when individuals have access to both complex, nonlinear priority information and simple, linear relative importance information, individuals can and do use the complex data in the intended way.
