Environmental sound recognition by timbre in children with Williams syndrome

Anecdotal reports have described children with Williams syndrome (WS) as presenting outstanding skills for recognizing environmental sounds by their timbre. This has led to suggest that the skills for environmental sound recognition by timbre are highly developed in WS. Furthermore, the term hypertimbria has been proposed to refer to this feature. However, no academic research has assessed these skills in WS. This study therefore aimed to contrast the reports on the highly developed skills for environmental sound recognition by timbre in children with WS. An environmental sound recognition task was administered to children with WS, children with Down syndrome of the same chronological age and cognitive level, and chronological age-matched typically developing children. Participants with WS performed significantly lower than their typically developing peers and no significant differences were found between the WS and Down syndrome groups. Unlike previous reports, this study points out that in WS environmental sound recognition by timbre does not constitute a phenotypic strength either in absolute or relative terms. Results suggest that children with WS do not present hypertimbria or preserved skills for timbre recognition. We discuss the implications of these results for theories of cognitive modularity.     

The Charcot Effect: The Invention of Mental Illnesses

This article proposes the Charcot effect, in which clinicians describe what they themselves prescribe. It is argued that the Charcot effect can be a critical instrument for exposing how mental illnesses are invented in the process of developing diagnostic systems and conducting psychopharmacological research. We argue that the Charcot effect helps explain the expansion of depression to epidemic proportions, the promotion of social phobia as a pharmaceutical marketing strategy, the profile of panic disorder according to the available medication, and the worse prognosis of schizophrenia in developed countries than in developing countries. Having undertaken this review, we situate the Charcot effect in relation to constructivist psychology.     

Auditory Verbal Hallucinations as Dialogical Experiences

The purpose of this study is to offer a model in which auditory verbal hallucinations (AVHs) can be conceptualized as dialogical experiences. This model is of interest in that it integrates several different perspectives (phenomenological, cognitive, social, and evolutionary) and the findings of empirical research on the subject. Hallucinations are understood as the product of a state of consciousness in which the self is dissociated into different positions or perspectives. After reviewing the most relevant results of psychological research, dialogical self theory is proposed as the theoretical framework for understanding hallucinatory experiences. It is argued that the voices possess a series of characteristics, pragmatic properties, relationships with the voices similar to their social surroundings, and more dissociative experiences in people who experience voices than in those who do not, with which they may be considered a dialogical experience. Finally, a model attempting to integrate psychological research on AVHs within the framework of dialogical self theory is presented.     

Rapid learning in attention shifts: A review

Many lines of evidence show that the human visual system does not simply passively register whatever appears in the visual field. The visual system seems to preferentially “choose” stimuli according to what is most relevant for the task at hand, a process called attentional selection. Given the large amount of information in any given visual scene, and well-documented capacity limitations for the representation of visual stimuli, such a strategy seems only reasonable. Consistent with this, human observers are surprisingly insensitive to large changes in their visual environment when they attend to something else in the visual scene. Here I argue that attentional selection of pertinent information is heavily influenced by the stimuli most recently viewed that were important for behaviour. I will describe recent evidence for the existence of a powerful memory system, not under any form of voluntary control, which aids observers in orienting quickly and effectively to behaviourally relevant stimuli in the visual environment, in particular the stimuli that have been important in the immediate past. I will also discuss research into the potential neural mechanisms involved in these learning effects. Finally, I will discuss how these putative memory mechanisms may help in maintaining the apparent stability and continuity of the ever-changing visual environment, which is such a crucial component of our everyday visual experience.     

Perceiving low self‐esteem in close others impedes capitalization and undermines the relationship

Disclosing positive experiences to others (i.e., “capitalization”) is associated with personal and interpersonal benefits (Gable & Reis, 2010). Unfortunately, people who perceive low self‐esteem (LSE) in close others are reluctant to capitalize, holding back from those they expect will be unsupportive (MacGregor & Holmes, 2011). In Study 1, we extend previous findings by demonstrating the importance of the type of experience disclosed; participants capitalized less positively with an (ostensibly) LSE friend when disclosing an accomplishment, not a positive experience attributed to happenstance. In Study 2, we demonstrate the external validity of the phenomenon by examining real discussions between romantic partners. Participants capitalized less positively with their LSE partner, behavior associated with lower relationship satisfaction 6 weeks later (particularly for women).     

Psychometric properties of a revised Spanish 20-item Toronto Alexithymia Scale adaptation in multiple sclerosis patients

There have been a small number of investigations of alexithymia in multiple sclerosis (MS) using the 20-item Toronto Alexithymia Scale (TAS-20). However, the TAS-20 factor structure has not yet been evaluated in a MS patient sample, and earlier Spanish translations of this instrument require some improvement. We aimed to evaluate the factorial validity and reliability of an improved Spanish translation of the TAS-20 (the TAS-20-S). The TAS-20-S was completed by 221 MS patients. Confirmatory factor analysis was used to compare the fit of six different factor models. Internal consistency and retest reliability coefficients were also computed. The correlated three-factor model and the higher-order factor model made up of Difficulty Identifying Feelings, Difficulty Describing Feelings, and Externally Oriented Thinking achieved the best fit. Alpha coefficients ranged between .87 and .67; mean inter-item correlations ranged between .48 and .20; and retest correlations after 6 months ranged between .61 and .52. A high degree of alexithymia was present in 18.1% of the sample. Reliability and the traditional three-factor structure were demonstrated for the TAS-20-S, which can now be recommended for assessing an aspect of emotional processing in MS patients.     

Aprendiendo a usar el Researcher-ID como indicador de la producción científica

The research focused on the development of scientific production measurements implies a detailed and quite accurately procedure to avoid errors and misinterpretations by third parties. The use of public researcher profiles such as the Researcher ID among others, may appeal to simplify the process of direct search on databases. The purpose of this research is to analyze the Researcher ID profile as an indicator of scientific productivity in a sample of 8 Spanish professors of Personality, Evaluation and Psychological Treatment area and compare these professors searching them in the Web of Science, also respond to a disagreement generated from a previous study published in Psicothema and culminated in a letter, as that there are unfounded arguments exposed. The results show that there are inaccuracies in the Researcher ID's and therefore cannot be used as an indicator of scientific production, since this tool allows to include any record type (letters, meeting abstracts, etc…) even unrelated content to the Web of Science. These findings are discussed a view to the disagreement and previously mentioned and generated in Psicothema.     

Factor structure of the construct of adaptive behavior in children with and without intellectual disability

Although the presence of significant limitations in adaptive behavior constitutes one of the three necessary criteria for diagnosing intellectual disability, adaptive behavior structure has always been the subject of considerable controversy among researchers. The main goal of this study is to extend previous research results that provide further support to a multidimensional structure of conceptual, social, and practical skills compared to the unidimensional structure. One-factor and 3-correlated factors models as measured by 15 observable indicators were analyzed by means of confirmatory factor analysis (CFA), as well as their relationships with one second-order factor (i.e., adaptive behavior). To that end, 388 children with and without intellectual disabilities were assessed with the Diagnostic Adaptive Behavior Scale (DABS). Results of CFA indicated that the 3 first-order factors solution provides the best fit to the data. Reliability and validity of the multidimensional model were also analyzed through different methods such as the composite reliability and the average variance extracted. Finally, implications of these findings and possible directions for future research are discussed.
