Structural model of acculturation attitudes and related psychosocial variables: Empirical evidence in native Spaniards

This work falls within the framework of the study of acculturation processes of natives and immigrants. Its goal is to test an explanatory multi‐group model of natives' acculturation attitudes as a function of diverse psychosocial variables: Prejudice and natives' appraisal of their own culture (in a direct way) and inter‐group contact and perceived inter‐group similarity (in an indirect way). Participants were 499 Spaniards surveyed for their attitude towards Romanian immigrants and 493 towards Ecuadorian immigrants. The indicators used took into account three socio‐cultural spheres: peripheral, intermediate and central areas. This multi‐group model shows an adequate fit to the data.     

The effects of age and emotional valence on recognition memory: An ex‐Gaussian components analysis

The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex‐Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The τ parameter, often related to attention in the literature, was smaller for young than old participants in an ex‐Gaussian fit. Differences on the τ parameter might suggest poorer attentional performance in old participants.     

Understanding action language modulates oscillatory mu and beta rhythms in the same way as observing actions

The mu rhythms (8–13 Hz) and the beta rhythms (15 up to 30 Hz) of the EEG are observed in the central electrodes (C3, Cz and C4) in resting states, and become suppressed when participants perform a manual action or when they observe another’s action. This has led researchers to consider that these rhythms are electrophysiological markers of the motor neuron activity in humans. This study tested whether the comprehension of action language, unlike abstract language, modulates mu and low beta rhythms (15–20 Hz) in a similar way as the observation of real actions. The log-ratios were calculated for each oscillatory band between each condition and baseline resting periods. The results indicated that both action language and action videos caused mu and beta suppression (negative log-ratios), whereas abstract language did not, confirming the hypothesis that understanding action language activates motor networks in the brain. In other words, the resonance of motor areas associated with action language is compatible with the embodiment approach to linguistic meaning.     

Do Phonological Constraints on the Spoken Word Affect Visual Lexical Decision?

Reading a word may involve the spoken language in two ways: in the conversion of letters to phonemes according to the conventions of the language’s writing system and the assimilation of phonemes according to the language’s constraints on speaking. If so, then words that require assimilation when uttered would require a change in the phonemes produced by grapheme-phoneme conversion when read. In two experiments, each involving 40 fluent readers, we compared visual lexical decision on Korean orthographic forms that would require such a change (C stimuli) or not (NC stimuli). We found that NC words were accepted faster than C words, and C nonwords were rejected faster than NC nonwords. The results suggest that phoneme-to-phoneme transformations involved in uttering a word may also be involved in visually identifying the word.     

Inhibitory mechanism of the matching heuristic in syllogistic reasoning

A number of heuristic-based hypotheses have been proposed to explain how people solve syllogisms with automatic processes. In particular, the matching heuristic employs the congruency of the quantifiers in a syllogism — by matching the quantifier of the conclusion with those of the two premises. When the heuristic leads to an invalid conclusion, successful solving of these conflict problems requires the inhibition of automatic heuristic processing. Accordingly, if the automatic processing were based on processing the set of quantifiers, no semantic contents would be inhibited. The mental model theory, however, suggests that people reason using mental models, which always involves semantic processing. Therefore, whatever inhibition occurs in the processing implies the inhibition of the semantic contents.     

Music,identity, and musical ethnocentrism of young people in six Asian,Latin American,and Western cultures

Ethnomusicologists and sociologists have extensively discussed the symbolic role of music in the creation, maintenance, and expression of cultural and national identity, while the underlying social psychological processes remain unexplored. We elaborate psychological mechanisms of identity construction and identity expression through culture‐specific music preferences. We propose and test a model linking music preferences to national identity via musical ethnocentrism in six student samples from Brazil, Germany, Hong Kong, Mexico, New Zealand, and the Philippines. In each context, culture‐specific music styles were related to national identity of its listeners and musical ethnocentrism mediated these effects. This paper bridges culture‐specific and universal perspectives on music and identity by examining the underlying psychological processes in Asian, Latin, and Western cultures.     

School context and health in adolescence: The role of sense of coherence

The aim of this study was to examine the role of school variables and sense of coherence (SOC) in the explanation of health. For this purpose, data were collected from a representative sample of adolescents, aged 13 to 18 years, selected for the Health Behavior in School‐aged Children survey in Spain. Using Structural Equation Modelling, three nested models were tested that represented different hypothesized models of the relationships among school factors, SOC and health. According to goodness‐of‐fit indices, in the best model, school‐related stress and SOC mediated the influence of support from classmates and teachers on health, and SOC had a direct effect on stress. The results supported the idea that a supportive school climate and SOC are relevant to adolescents' health. Furthermore, SOC was the most influential variable; apart from its direct positive effect on health, SOC seemed to condition the degree to which students perceived school demands to be stressful. Specifically, students with a high SOC were less likely to suffer from high levels of school‐related stress.     

Androginia psicológica y flexibilidad comportamental

RESUMEN

Los autores investigan la hipótesis de que los sujetos andróginos son más flexibles en su implicación y bienestar ante tareas que se tipifican culturalmente como pertenecientes al “otro” sexo. Comienzan repasando la literatura psicológica acerca de androginia psicológica y flexibilidad comportamental y seguidamente concretan sus hipótesis: comprobar que los individuos andróginos a) mostrarán una mayor implicación en tareas tanto masculinas como femeninas, b) preferirán en menor medida actividades apropiadas a su sexo y c) experimentarán un mayor bienestar psicológico al desarrollar este tipo de actividades que cualquier otro grupo de rol sexual. Tras describir el método y los resultados del trabajo, los autores ofrecen una discusión final de éstos, en la que destacan que su investigación parece confirmar los resultados de Bem: parece que es el rol sexual andrógino el que siente un mayor grado de bienestar al realizar conductas que son sancionadas socialmente como inapropiadas a su sexo y el que escoge un mayor número de este tipo de comportamientos. Los autores finalizan afirmando que también parece haber quedado respaldada la validez predictiva del Bem Sex Role Inventory.     

Analysis of the conceptual structure of natural and artifactual categories in Alzheimer's disease patients

This work has two goals, the first one is to study in detail the conceptual structure of some natural and artifactual categories, by using multidimensional scaling (MDS). According to our theoretical approximation, conceptual structure is composed of semantic features, and these features have different entities and nature. As an index of relevance in mental representation of semantic categories, we took the frequency of production of semantic features on a free verbal production task. Our second goal was to compare the structure of conceptual representations in two populations, healthy elderly and Alzheimer's disease (AD) patients, assuming that conceptual representation is impaired in this last population. We assume that the impairment in the conceptual representations of AD patients will show, when the disease reaches a determined level, loosing specific features. This impairment will have serious consequences in the whole conceptual structure.
