Entrevista con Julián de Ajuriaguerra

RESUMEN

En esta entrevista Julián de Ajuriaguerra describe su historia científica desde que era interno en hospitales psiquiátricos y alumno de Thomas y Lhermitte, comentando los trabajos que realizó con adultos, ancianos y dementes aunque su interés estuviese desde un principio en los niños. Responde, entre otras, a cuestiones tales como si lo biológico se complementa con lo social en el desarrollo, cómo son los vínculos de los padres con el niño, cuál es su posición respecto al psicoanálisis, si es necesaria la interdisciplinariedad para hacer psicología o qué opina del problema de los estadios. También realiza un balance del estado actual de la psicomotricidad, ejemplifica qué entiende por “diálogo tónico” y explica las diferencias entre los juegos de niños y niñas de siete, ocho y nueve años, admitiendo la distinta organización tónica de los sexos. Por último el autor se centra en el trabajo clínico, ofreciendo sugerencias para aquéllos que empiezan a llevarlo a cabo en España. Los comentarios que Ana María Pardo y Ángel Rivière realizan del autor y su obra introducen esta entrevista.     

Implicit ambivalence from attitude change: an exploration of the PAST model

Traditional models of attitude change have assumed that when people appear to have changed their attitudes in response to new information, their old attitudes disappear and no longer have any impact. The present research suggests that when attitudes change, the old attitude can remain in memory and influence subsequent behavior. Four experiments are reported in which initial attitudes were created and then changed (or not) with new information. In each study, the authors demonstrate that when people undergo attitude change, their old and new attitudes can interact to produce evaluative responses consistent with a state of implicit ambivalence. In Study 1, individuals whose attitudes changed were more neutral on a measure of automatic evaluation. In Study 2, attitude change led people to show less confidence on an implicit but not an explicit measure. In Studies 3 and 4, people whose attitudes changed engaged in greater processing of attitude-relevant information than did individuals whose attitudes were not changed.     

Depression as a predictor of perceived social support and demand: a componential approach using a prospective sample of older adults

This study examined the relationship of the cognitive, mood, and somatic components of depression on perceptions of social support and social demand among older adults (n = 851) over two years. Factor-analyses confirmed the factor structure of our multicomponential model of depression. Results supported our proposal that interpersonal specificity, as measured by depressive cognition about self and others, is important to predicting changes in perceived support and demand over time. Each component of depression was related to social support and social demand cross-sectionally, whereas only the cognitive component of depression predicted changes in support and demand prospectively. Future research should consider the pathways linking depressive cognition to perceived support and demand.     

Hippocampal gene expression profiling in spatial discrimination learning

Learning and long-term memory are thought to involve temporally defined changes in gene expression that lead to the strengthening of synaptic connections in selected brain regions. We used cDNA microarrays to study hippocampal gene expression in animals trained in a spatial discrimination-learning paradigm. Our analysis identified 19 genes that showed statistically significant changes in expression when comparing Nai;ve versus Trained animals. We confirmed the changes in expression for the genes encoding the nuclear protein prothymosin(alpha) and the delta-1 opioid receptor (DOR1) by Northern blotting or in situ hybridization. In additional studies, laser-capture microdissection (LCM) allowed us to obtain enriched neuronal populations from the dentate gyrus, CA1, and CA3 subregions of the hippocampus from Nai;ve, Pseudotrained, and spatially Trained animals. Real-time PCR examined the spatial learning specificity of hippocampal modulation of the genes encoding protein kinase B (PKB, also known as Akt), protein kinase C(delta) (PKC(delta)), cell adhesion kinase(beta) (CAK(beta), also known as Pyk2), and receptor protein tyrosine phosphatase(zeta/beta) (RPTP(zeta/beta)). These studies showed subregion specificity of spatial learning-induced changes in gene expression within the hippocampus, a feature that was particular to each gene studied. We suggest that statistically valid gene expression profiles generated with cDNA microarrays may provide important insights as to the cellular and molecular events subserving learning and memory processes in the brain.     

Improving attitudes towards minority groups by thinking about the thoughts and meta-cognitions of their members

Research on persuasion has shown that for attitudes to change people need to take into consideration not only the thoughts message recipients generate in response to proposals but also how people think about their own thoughts (metacognition). In the present research, we introduce a new perspective for improving outgroup attitudes focused on the distinction between cognition and metacognition but this time applied to the perceptions of others’ minds. Specifically, we examined to what extent thinking about the mental processes of outgroup members influences attitudes towards those outgroups. We compared the impact of thinking about how others think (perceived primary cognition) with how others think about their own thoughts (perceived secondary cognition or metacognition). In the primary cognition treatment, participants answered questions about the thinking processes of outgroup members. In the secondary cognition treatment, participants answered questions that required them to consider how outgroup members think about their own thoughts (i.e., metacognition). Compared to controls, these treatments were capable of improving attitudes of Spanish citizens towards Syrian refugees, South American immigrants, and Roma people. A third study used a minimal group paradigm in which a fictitious outgroup was described as having primary (vs. secondary) cognition. A final study also tested the implications of assuming that groups have one type of cognition or another. The effects of the two treatments varied depending on the type of outgroup.     

Mediation of the stigma in the influence of negative symptomatology over recovery in psychosis

Background/Objective: The interest in recovery processes in psychotic disorders has boosted the necessity of knowledge about the factors that could influence in such recovery. Negative symptomatology and the stigma have been negatively linked to the recovery process in psychosis. The aim of this investigation is to improve the understanding of how the recovery process is affected by negative symptomatology based on the analysis of the mediating effects of the internalized stigma. Method: The sample was composed of 114 people that had experienced, at some point in their life, at least one clinically relevant psychotic episode. CAPE-42, STORI and ISMI were used for the evaluation. The macro PROCESS for SPSS was used. The indirect effect was calculated using 10.000 samples of bootstrap for the bootstrap confidence intervals (IC) corrected for bias. Results: The results show that the influence of negative symptomatology predicts the stigmatization of the person regarding his disorder. This predicts a negative influence in the recovery process of the psychosis. Conclusions: These results back the importance of adding the reduction of the stigma as a specific strategy to improve the recovery process in psychotic disorders.     

Humean laws,circularity, and contrastivity

Synthese - A well-known objection to Humean accounts of laws (e.g. BSA, Lewis in Australas J Philos 61:343–377, 1983, Philosophical papers vol. II, Oxford University Press, 1986) charges them...     

Balancing fit and parsimony to improve Q-matrix validation

The Q-matrix identifies the subset of attributes measured by each item in the cognitive diagnosis modelling framework. Usually constructed by domain experts, the Q-matrix might contain some misspecifications, disrupting classification accuracy. Empirical Q-matrix validation methods such as the general discrimination index (GDI) and Wald have shown promising results in addressing this problem. However, a cut-off point is used in both methods, which might be suboptimal. To address this limitation, the Hull method is proposed and evaluated in the present study. This method aims to find the optimal balance between fit and parsimony, and it is flexible enough to be used either with a measure of item discrimination (the proportion of variance accounted for, PVAF) or a coefficient of determination (pseudo-R²). Results from a simulation study showed that the Hull method consistently showed the best performance and shortest computation time, especially when used with the PVAF. The Wald method also performed very well overall, while the GDI method obtained poor results when the number of attributes was high. The absence of a cut-off point provides greater flexibility to the Hull method, and it places it as a comprehensive solution to the Q-matrix specification problem in applied settings. This proposal is illustrated using real data.     

Are emotionally intelligent people less prejudiced? The importance of emotion management skills for outgroup attitudes

People vary in their ability to understand, process, and manage information about one's own and others’ emotions, a construct known as Emotional Intelligence (EI). Past research highlighted the importance of EI in interpersonal relations as well as the key role of emotions underlying outgroup prejudice. Remarkably, hardly any research has investigated the associations between EI and outgroup prejudice. In three studies (total N = 922) conducted in Spain and the United Kingdom, we measured emotional intelligence using self-report and performance tests and prejudice toward a variety of outgroups. Results showed that those with stronger performance-based emotion management skills expressed lower generalized ethnic prejudice (Studies 1–3), more positive attitudes toward immigrants (Study 2a) and refugees (Study 2b), and less homophobic attitudes (Study 3). This negative association between emotion management and prejudice was found with different performance-based EI measures and held after controlling for self-perceived EI (Study 1) and self-reported abilities to regulate emotions (Study 3). Study 3 further demonstrated that higher empathy partly accounted for the association between emotion management and prejudice. The findings suggest that emotion management abilities play an important, but so far largely neglected role in generalized prejudice.
