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.     

The Effect of Authority on the Persuasiveness of Mathematical Arguments

Three experiments are reported that investigate the extent to which an authority figure influences the level of persuasion undergraduate students and research-active mathematicians invest in mathematical arguments. We demonstrate that, in some situations, both students and researchers rate arguments as being more persuasive when they are associated with an expert mathematician than when the author is anonymous. We develop a model that accounts for these data by suggesting that, for both students and researchers, an authority figure only plays a role when there is already some uncertainty about the argument's mathematical status. Implications for pedagogy, and for future research, are discussed.     

Psychometric properties of the Interpersonal Reactivity Index in Spanish child and adolescent population

This article analyses the dimensions of the Interpersonal Reactivity Index (IRI; Davis, 1980). The sample comprised 721 Spanish participants between 9 and 16 years old. Diverse exploratory factor analyses were conducted as the basis for the final confirmatory factor analysis, through self-report. The results supported a structure with 5 first-order main factors (Intellectual empathy, Positive emotional empathy, Disorganized emotional empathy, Virtual empathy, and Impassiveness), where the two first factors are nested in a second-order dimension: "Considerate Social Style". The psychometric characteristics of the instrument were adequate. The proposed model is a new alternative to conceptualize the factor structure of empathy.     

How Coincidence Bears on Persistence

The ‘paradoxes of coincidence’ are generally taken as an important factor for deciding between rival views on persistence through time. In particular, the ability to deal with apparent cases of temporary coincidence is usually regarded as a good reason for favouring perdurantism (or ‘four-dimensionalism’) over endurantism (or ‘three-dimensionalism’). However, the recent work of Gilmore (2007) and McGrath (2007) challenges this standard view. For different reasons, both Gilmore and McGrath conclude that perdurantism does not really obtain support from the puzzles of temporary coincidence. In this paper, I will evaluate their arguments and defend the opposite view: that the paradoxes of coincidence do give some support to perdurantism. However, the way in which they do so is rather unexpected. As we will see, there are different ways in which coincidence scenarios may be thought to support perdurantism, some of which have not yet been sufficiently explored. Thus, my immediate goal is to explore one of those directions, bringing into focus a new argument from coincidence to perdurantism. And although I motivate my discussion by examining the arguments in the work of Gilmore and McGrath, the merits of this argument can be independently assessed. More generally, my overall purpose is to contribute to our general understanding of how the topics of coincidence and persistence bear on each other.     

Emotional valence modulates the preference for curved objects

Previous studies have shown that people prefer objects with curved contours over objects with sharp contours. However, those studies used stimuli that were mainly neutral in emotional valence. We tested here the interplay between visual features and general valence as positive or negative. After replicating curvature preferences for neutral objects, we used positive (cake, chocolate) and negative (snake, bomb) stimuli to examine if emotional valence-through response prioritisation-modulates the preference for curved objects. We found that people indeed preferred the curved versions of objects to the sharp versions of the same objects, but only if the objects were neutral or positive in emotional valence. There were no difference in liking for objects with negative emotional valence. This is evidence that the aesthetic response is adaptive, in this case prioritising valence over contour as demanded by the general semantic classification.     

Factor structure and longitudinal invariance of the Medical Adherence Report Scale-Asthma

Adequate assessment of adherence to medical treatment is critical for both research purposes and clinical practice. This study examined the factor structure and longitudinal invariance of the Medication Adherence Report Scale (MARS-A10) in a sample of asthmatic patients. We examined longitudinal data from 294 inner-city, adult participants with moderate to severe asthma. Because of ambiguous evidence regarding the dimensionality of the MARS-A10, the data was analysed with exploratory structural equation modelling. We first proceeded by determining the dimensionality of the scale at baseline and examined whether the structure, loadings, intercepts and errors were invariant over the four assessments points. Results indicated that a two-factor structure (factor 1: non-adherence based on experiential changes; factor 2: non-adherence based on intentional medication avoidance) had the best fit to the data (χ(2)(25)=37.69, p=0.05). Longitudinal analyses revealed that the nine items assessing intentional non-adherence were invariant over time. The evidence from the factor analysis suggests that intentional non-adherence is a multidimensional construct. Additionally, longitudinal data provided strong evidence that the items examining intentional non-adherence are invariant over time, indicating that changes in non-adherence scores can be validly attributed to changes in behaviour.     

Masked nonword repetition effects in yes/no and go/no-go lexical decision: A test of the evidence accumulation and deadline accounts

The pattern of masked repetition priming effects for word and nonword targets differs across tasks: Maskedpriming effects in lexical decision occur for positive responses (i.e., words), but not for negative responses (nonwords), whereas masked-priming effects in the cross-case same-different task occur for positive responses (same), but not for negative responses (different)—regardless of lexical status. Here, we examined whether masked nonword priming effects are greater when the task involves an active go response to nonwords than when it involves the standard yes/no procedure in lexical decision. The obtained masked repetition priming effect for nonwords was of similar size in yes/no and go/no-go tasks. This finding is compatible with accounts of nonword priming that posit that nonword responses are produced by actively accumulating evidence for the nonword alternative in yes/no and go/no-go procedures, whereas it is inconsistent with the assumption of a deadline for no responses in the yes/no task.     

System‐perpetuating asymmetries between explicit and implicit intergroup attitudes among indigenous and non‐indigenous Chileans

The present research demonstrates a dissociation between explicit and implicit intergroup evaluation in the reciprocal attitudes between indigenous (Mapuche) and non‐indigenous Chileans. In both social groups, the explicit measures of attitudes towards the respective in‐group and out‐group were compared with the Implicit Association Test scores. The results indicate that the members of the low‐status minority might explicitly express a moderate evaluative preference for their in‐group but might implicitly devalue it. Conversely, the members of the high‐status majority might implicitly devalue their out‐group but might explicitly express no bias. These results are theoretically framed in terms of system justification, conventional stereotypes and motivated correction processes.     

Investigating stereotype structure with empirical network models

In this work we present empirical network models as a new approach in the investigation of stereotype structure. We will argue that empirical network models can provide more insight into stereotype structure because they do not suffer from the inherent constraints of factor analysis and multidimensional scaling (e.g., group features interpreted homogeneously only on the basis of their shared variance, impossibility to adequately represent cognitive schemas, difficulties to make inferences on the basis of dimensions potentially overlapping). In the present research we show how empirical network models can represent stereotypes as dynamic cognitive structures clustered in different substructures. These structures will be based on both the stereotype content and the co-occurrence of features in each group target. Additionally, this research shows how using empirical networks can contribute to broadening the interpretation of stereotypes representing them in the framework of prejudice or intergroup attitudes.     

Reading Difficulties in Low-SES Children: A Study of Cognitive Profiles

Reading difficulties of children growing up in poverty contexts have not received as much attention as those of children from middle-income families. This paper analyzes the reading-related cognitive profiles of Argentine, Spanish-speaking, low-SES children with reading difficulties (RD), by comparing them with chronological age- (CA) and reading age- (RA) matched children from the same socioeconomic background. Ninety children (30 in each group) participated in the study. Testing included reading, spelling, verbal memory, phonological sensitivity, rapid naming, letter knowledge, and vocabulary measures. Results showed that children from the RD group performed significantly worse than their same-age peers. These findings would suggest the presence of a cognitive vulnerability in children with reading difficulties. Interestingly, when compared with children from the RA-matched control group, children in the RD group only obtained significantly lower scores in phoneme segmentation and letter-sound recognition tasks. Cognitive profiles of low-income children growing in poverty differ from cognitive profiles described for middle-income children with dyslexia. Given that teaching of letter sounds is not included in Argentina’s mandatory curriculum, it is possible that letter-sound teaching constitutes an environmental factor that interacts with other risk factors to produce reading difficulties in poverty contexts.
