Discourse-based emotional consistency modulates early and middle components of event-related potentials

In this study, participants read stories describing emotional episodes with either a positive or negative valence (Experiment 1). Following each story, participants were exposed to short sentences referring to the protagonist, and the event-related potential (ERP) for each sentence's last word was recorded. Some sentences described the protagonist's emotion, either consistent or inconsistent with the story; others were neutral; and others involved a semantically anomalous word. Inconsistent emotions were found to elicit larger N100/P200 and N400 than consistent emotions. However, when participants were exposed to the same critical sentences in a control experiment (Experiment 2) in which the stories had been removed, emotional consistency effects disappeared in all ERP components, demonstrating that these effects were discourse-level phenomena. By contrast, the ordinary N400 effect for locally anomalous words in the sentence was obtained both with and without story context. In conclusion, reading stories describing events with emotional significance determines strong and very early anticipations of an emotional word.     

Afro-centric religious consultations as treatment for psychotic disorders among day hospital patients in Santiago de Cuba

We investigated the utilisation of Afro-centric religious treatments for psychotic disorders among a sample of Cuban day hospital patients. Most (55%) had used such treatments and this practice was more common among older persons, although unassociated with any particular religious background or racial heritage. Persons who preferred Afro-centric religious practices to medical ones were more likely to be of African descent or to have received an Afro-centric religious ritual bath as treatment. A case is made for destigmatising Afro-centric religious treatments and for exploring treatment approaches that combine both medical and religious practices in order to achieve more holistic care.     

Eighteen-month-old human infants show intensive development in comprehension of different types of pointing gestures

This study explored children’s development in comprehending four types of pointing gestures with different familiarity. Our aim was to highlight human infants’ pointing comprehension abilities under the same conditions used for various animal species. Sixteen children were tested longitudinally in a two-choice task from 1 year of age. At the age of 12 and 14 months, infants did not exceed chance level with either of the gestures used. Infants were successful with distal pointing and long cross-pointing at the age of 16 months. By the age of 18 months, infants showed a high success rate with the less familiar gestures (forward cross-pointing and far pointing) as well. Their skills at this older age show close similarity with those demonstrated previously by dogs when using exactly the same testing procedures. Our longitudinal studies also revealed that in a few infants, the ability to comprehend pointing gestures is already apparent before 16 months of age. In general, we found large individual variation. This has been described for a variety of cognitive skills in human development and seems to be typical for pointing comprehension as well.     

Characterization of long-term memory, resistance to extinction, and influence of temperament during two instrumental tasks in horses

The present study investigated the influence of temperament on long-term recall and extinction of 2 instrumental tasks in 26 horses. In the first task (backward task), horses learned to walk backward, using commands given by an experimenter, in order to obtain a food reward. In the second task (active avoidance task), horses had to cross an obstacle after a bell rang in order to avoid emission of an air puff. Twenty-two months after acquisition, horses exhibited perfect recall performance in both tasks. Accordingly, no influence of temperament on recall performance could be observed for either task. In contrast, in the absence of positive or negative outcomes, the horses’ ability to extinguish their response to either task was highly variable. Resistance to extinction was related to some indicators of temperament: The most fearful horses tended to be the most resistant to extinction in the backward task, while the least sensitive horses tended to be the most resistant to extinction in the active avoidance task. These findings reveal extensive long-term memory abilities in horses and suggest an influence of temperament on learning processes other than acquisition.     

Interactive effects of personality and separation as acculturation style on adolescent antisocial behaviour

The primary aim of this study was to assess the interaction between personality and acculturation variables in predicting antisocial behaviour among adolescent immigrants living in Spain. Previous studies have shown that the acculturation style referred to as separation (rejection of the host country's culture, and a strong desire to preserve the culture of the country of origin) was strongly related to antisocial behaviour among immigrants. A further aim of this study was to examine if the relationship between separation and antisocial behaviour was moderated by personality variables, in particular impulsivity, sensation-seeking, and personal competence. Self-reported data of a sample of 750 adolescent immigrants living in Galicia's and Madrid's regions (Spain) were gathered using previously validated scales. The results revealed that both separation and personality variables were significantly related to antisocial behaviour. Moreover, hierarchical regression analysis with the interaction terms entered found significant moderating effects i.e., the relationship between separation and antisocial behaviour was significantly amplified when impulsivity or sensation-seeking were high. The results underscore the need to examine the effects of personality, acculturation, and the interaction between both on antisocial behaviour among adolescent immigrants.     

El lenguaje autista desde una perspectiva correlacional

Resumen

A pesar del interés reciente por las alteraciones del lenguaje en autismo infantil, es notable la carencia de investigaciones en que se analicen las correlaciones de las variables de lenguaje entre sí y con otra variables comportamentales. En este artículo se realiza tal análisis, correlacionando variables lingüísticas entre sí (L.M.E., complejidad estructural, comprensión, porcentaje de ecos y habla socializada, etc.) y con variables no lingüísticas (cociente global de desarrollo, niveles de imitación, percepción, motricidad, integración óculo-manual y cognitivo y cognitivo-verbal, P.P.O.D.). El análisis de los datos intragrupales permite identificar índices lingüísticos, de interés para guiar la evaluación clínica, porporciona una base para la valoración pronostica y permite situar las alteraciones de lenguaje en un contexto global de anomalías que afectan a la construcción de la conducta intencional, el desarrollo de los códigos simbólicos y las conductas de relación e interacción presimbólica.     

Obediencia institucional en el laboratorio

Resumen

La presente investigación consistió en una réplica de los paradigmas experimentales de Milgram y Darley y Latané sobre conformidad y conducta de ayuda. Se utilizaron 28 S divididos en un grupo de control y uno experimental. La V.I. era la presencia o ausencia de una supuesta víctima que, en una estancia contigua, recibía descargas eléctricas contra su voluntad. La V.D. estudiada era la obediencia o no a las instrucciones del experimentador por parte de los S en ambas situaciones. Los resultados confirman los de anteriores trabajos al observarse altos porcentajes de conductas conformistas. Por último se discuten tales datos en base a su relevancia ecológica.     

La perspectiva cualitativa y cuantitativa en las investigaciones sociales

RESUMEN

El debate sobre la utilización de métodos y paradigmas cualitativos versus cuantitativos afecta al programa general de la psicología y está planteado desde la constitución de la ciencia Psicológica. En este artículo se presenta el debate, y se cuestiona el planteamiento tradicional consistente en vincular conjuntos definidos y cerrados de prescripciones teóricas a uno y otro tipo de métodos, presentándolas como alternativas irreconciliables. Este planteamiento es rechazado y sustituido por uno en el que; 1) Es de un claro reconocimiento al carácter científico de la perspectiva cualitativa, 2) Haga una primera aproximación a las posibilidades de la utilización conjunta de ambas perspectivas, 3) Haga una clara distinción entre dos niveles diferentes; nivel paradigmático/epistemológico y nivel metodológico/técnico.     

Estrategias de comprensión del lenguaje. El desarrollo de la capacidad metalingüística

RESUMEN

Es este un artículo dedicado a la capacidad metalingüística, en la compresión de lenguaje, en el que se precisan algunas de las ideas de anteriores trabajos, sobre la génesis de la capacidad metalingüística del niño. Se basa el trabajo en la necesidad de emplear claves contextuales en las funciones de compresión (de la distinción sujeto-objeto, en este caso). La investigación presentada permite establecer varios niveles en las estrategias de compresión y captación de errores lingüísticos, centrándose especialmente en un nivel “intermedio” de desarrollo de la competencia metalingüística, caracterizado por respuestas oscilatorias entre los niños que requieren claves contextuales (aunque sean internas) para permitir la comprensión y aquellos otros, de nivel “formal”, en que dichas claves ya no son necesarias y de una captación consistente de los errores lingüísticos.
