Individual Differences in Diving: Intelligence,Personality, and Underwater Adaptation

Diving is an activity that is carried out in an extreme environment with extraordinary psychophysical demands. It requires the divers to undergo an adaptive process in order to survive, to be able to take advantage of their capabilities, and to achieve an efficient performance. In this ex post facto study, data from a sample of military personnel participating in scuba diving courses (N = 649) were analyzed. Our aim was to verify the role of individual differences in the adaptation to an extreme and hostile environment. The results indicate the existence of psychological variables that differentiate between divers and the general population, those who pass or fail the diving course, and between groups of divers who obtain differential levels of performance in underwater tasks. These findings support that dispositional characteristics have utility for the identification of suitable personnel for professional diving.     

A new model of sportive cooperation and its evaluation by means a questionnaire

We present in this paper the sportive cooperation as a theoretical framework for the teams' dynamics, and as an alternative to others theories, specially the sportive cohesion. This theory has a double basis: 1) The rational and utilitarist decision taking upon the personal cooperation or not, with the team's goal, based on the internal teammates interaction, and the environmental stimuli; and 2) A personal, and more stable, disposition to cooperate, despite the possibility of obtain any counterparts for this behavior. From this framework, we have build--in a three phase process--a questionnaire addressed to evaluate the sportive cooperation. The final version--composed of 15 items with standard psychometric propierties--shows two kinds of factors. First, we have two dispositional, traitlike, factors: The Conditional cooperation, and the Unconditional cooperation. Second, we have three situational factors: the Cooperation with the Coach, with the teammates, and the Cooperation outside the game and the training. Lastly, we discuss the maining of this theory respect to the sportive team's dynamics, and its relevance for the applied psychology, both for the evaluation and the interventions on the teams.     

Selective attention affects implicit and explicit memory for familiar pictures at different delay conditions

Three experiments investigated the effects of two variables -selective attention during encoding and delay between study and test- on implicit (picture fragment completion and object naming) and explicit (free recall and recognition) memory tests. Experiments 1 and 2 consistently indicated that (a) at all delays (immediate to 1 month), picture-fragment identification threshold was lower for the attended than the unattended pictures; (b) the attended pictures were recalled and recognized better than the unattended; and (c) attention and delay interacted in both memory tests. For implicit memory, performance decreased as delay increased for both attended and unattended pictures, but priming was more pronounced and lasted longer for the attended pictures; it was still present after a 1-month delay. For explicit memory, performance decreased as delay increased for attended pictures, but for unattended pictures performance was consistent throughout delay. By using a perceptual object naming task, Experiment 3 showed reliable implicit and explicit memory for attended but not for unattended pictures. This study indicates that picture repetition priming requires attention at the time of study and that neither delay nor attention dissociate performance in explicit and implicit memory tests; both types of memory require attention, but explicit memory does so to a larger degree.     

Pretend play: an application of an intervention program in autism

Methodologically and theoretically based on metarrepresentational deficit hypothesis, we design an intervention to teach the mental state of pretense to an autistic boy. The production and comprehension of symbolic play by means of the use of two specific strategies founded on pictorial analogy of the mental representation and process, was the focus of the learning. The efficiency and efectiveness of the program is reflected in the results that indicated the subject's competence to generate and comprehend the pretense as well as to generalize the acquired knowledge into other areas of mentalistic functioning. We discuss the possibility to develop a metarrepresentational knowledge based on the internalizing of the strategies of conceptual support.     

Cortical memory mechanisms and language origins

We have previously proposed that cortical auditory-vocal networks of the monkey brain can be partly homologized with language networks that participate in the phonological loop. In this paper, we suggest that other linguistic phenomena like semantic and syntactic processing also rely on the activation of transient memory networks, which can be compared to active memory networks in the primate. Consequently, short-term cortical memory ensembles that participate in language processing can be phylogenetically tracked to more simple networks present in the primate brain, which became increasingly complex in hominid evolution. This perspective is discussed in the context of two current interpretations of language origins, the "mirror-system hypothesis" and generativist grammar.     

Psychometric Properties and Clinical Cut-Off Scores of the Spanish Version of the Social Anxiety Scale for Adolescents

Psychotic (P) and Non-Psychotic (N-P) retardates were compared on 13 Rorschach “indicators” of psychosis using a matched pairs technique. Two of the 13 signs were found to significantly differentiate between groups with the P group demonstrating a lower F% and higher C' responding than the N-P group.     

Un estudio sobre el efecto de la figura en el razonamiento silogístico

Resumen

Los estudios sobre el razonamiento con silogismos categóricos han demostrado que la disposición de los términos de las premisas en las figuras 1 y 4, influye en la elección del sujeto y el predicado de la conclusión y, por tanto, afecta a la dificultad del silogismo. El objetivo de este estudio fue comprobar, además de la hipótesis general, la hipótesis del «razonamiento-ancla». Esta hipótesis precide en las combinaciones donde una de las premisas es universal afirmativa (AE, EA, AI, IA, AO y OA), la existencia también de un efecto figural en las figuras 2 y 3. Ambas hipótesis fueron comprobadas dentro de un diseño de covarianza con dos grupos, realizado para contrastar un modelo general del razonamiento silogístico. Los sujetos fueron 60 alumnos de C.O.U., cada uno de ellos recibió un cuadernillo con 32 combinaciones de premisas, formando entre los dos grupos el total de 64 combinaciones posibles. Los resultados se compararon con los de otros autores y se discutieron en el contexto de sus semejanzas con algunos estudios de las series de tres términos.     

“Ningún Iroqués era Mohicano”: La influencia del contenido en las tareas de razonamiento lógico

Resumen

Este estudio se centra en la influencia del contenido de la tarea en problemas de razonamiento deductivo. Se utilizaron cuatro tareas diferentes: de razonamiento proposicional, usando deferentes tipos de conectivas lógicas, silogismos lineales o series de tres términos, silogismos categoriales y la tarea selección de Wason. Para cada una de las tareas se diseñaron dos versiones: una con material temático concreto, diferente para cada tarea y una segunda versión con material abstracto, sin contenido temático concreto. Ambas versiones de la misma tarea eran isomóificas. Se administraron ambas versiones de las cuatro tareas, en el mismo orden comentado, a dos grupos de sujetos: un grupo realizó siempre primero la versión concreta y luego la abstracta y otro grupo realizó siempre la abstracta y después la concreta. Los sujetos fueron alumnos de enseñanza secundaria (3.^er año), 37 y 38 sujetos respectivamente, con una media de edad de 17 años.

Los resultados confirman que no se produce un único efecto facilitador o dificultador del contenido. En una tarea la versión de contenido resulta más fácil, en otra más dificil y en otras dos no hay diferencias. El efecto mayor se produce en aquella tarea en que los sujetos parecen disponer de un «esquema de permiso» muy claro sobre el contenido temático de la tarea. Los resultados se interpretan en base a una hipótesis de doble procesamiento sintáctico y semántico. En cuanto al efecto facilitador del orden de presentación (abstracto-concreto; concreto-abstracto) los resultados indican que la versión concreta facilita la abstracta pero que la abstracta dificulta la ejecución en la concreta. Estos resultados irían en la línea de presuponer una primacía de procesamiento semántico sobre el sintáctico.
