Memory for emotional words: The role of semantic relatedness,encoding task and affective valence

Emotional stimuli have been repeatedly demonstrated to be better remembered than neutral ones. The aim of the present study was to test whether this advantage in memory is mainly produced by the affective content of the stimuli or it can be rather accounted for by factors such as semantic relatedness or type of encoding task. The valence of the stimuli (positive, negative and neutral words that could be either semantically related or unrelated) as well as the type of encoding task (focused on either familiarity or emotionality) was manipulated. The results revealed an advantage in memory for emotional words (either positive or negative) regardless of semantic relatedness. Importantly, this advantage was modulated by the encoding task, as it was reliable only in the task which focused on emotionality. These findings suggest that congruity with the dimension attended at encoding might contribute to the superiority in memory for emotional words, thus offering us a more complex picture of the underlying mechanisms behind the advantage for emotional information in memory.     

Young Tennis Players’ Competitive Task Involvement and Performance: The Role of Goal Orientations,Contextual Motivational Climate,And Coach-Initiated Motivational Climate

The purpose of this study was to examine the role of situational and dispositional factors in contributing to competitive task involvement and performance in young tennis players. One hundred fifty-one adolescent tennis players and their coaches participated in the study. Participants responded to instruments measuring pre-game dispositional goal orientations and perceptions of the motivational climate and post-game task involvement in the competition by assessing concentration, loss of self-consciousness, and autotelic experience, perceptions of coach-initiated motivational climate in competition, and self-evaluation of game performance. In addition, coaches evaluated the players’ performance. Results showed that task involvement was predicted by players’ perceptions of a coach-initiated learning motivational climate in competition. Loss of self-consciousness was predicted by the players’ perceptions of a coach-initiated performance climate in competition. Finally, coaches’ and players’ assessment of performance were predicted by autotelic experience, concentration, and by perception of coach-initiated learning and performance orientation in competition.     

Differences in negative life events between patients with anxiety disorders,depression and hypochondriasis

This study investigated whether some categories of adverse life events are differentially associated with specific types of emotional disorders. A life self-report measure of major life events was completed by 42 subjects with diagnoses of anxiety disorders, 46 subjects with major depression, 26 subjects with hypochondriasis and 73 nonclinical subjects (controls). As predicted, the onset of anxiety disorders, depression, and hypochondriasis appears to be differentially related with life stress of ‘threat’, ‘loss’, and ‘health’, respectively, previously experienced by the clinical subjects. Also, there were significant differences between clinical and nonclinical subjects on both perceived life stress and number of life events reported. Findings suggest a differential implication of psychosocial stress categories in particular emotional disorders (i.e., anxiety, depressive and hypochondriacal disorders). These results expand previous findings that have demonstrated an association between negative life events and psychopathology.     

Perception of the Ebbinghaus illusion in four-day-old domestic chicks (Gallus gallus)

In the Ebbinghaus size illusion, a central circle surrounded by small circles (inducers) appears bigger than an identical one surrounded by large inducers. Previous studies have failed to demonstrate sensitivity to this illusion in pigeons and baboons, leading to the conclusion that avian species (possibly also nonhuman primates) might lack the neural substrate necessary to perceive the Ebbinghaus illusion in a human-like fashion. Such a substrate may have been only recently evolved in the primate lineage. Here, we show that this illusion is perceived by 4-day-old domestic chicks. During rearing, chicks learnt, according to an observational-learning paradigm, to find food in proximity either of a big or of a small circle. Subjects were then tested with Ebbinghaus stimuli: two identical circles, one surrounded by larger and the other by smaller inducers. The percentage of approaches to the perceptually bigger target in animals reinforced on the bigger circle (and vice versa for the other group) was computed. Over four experiments, we demonstrated that chicks are reliably affected by the illusory display. Subjects reinforced on the small target choose the configuration with big inducers, in which the central target appears perceptually smaller; the opposite is true for subjects reinforced on the big target. This result has important implications for the evolutionary history of the neural substrate involved in the perception of the Ebbinghaus illusion.     

Some topological properties of paraconsistent models

In this work, we investigate the relationship between paraconsistent semantics and some well-known topological spaces such as connected and continuous spaces. We also discuss homotopies as truth preserving operations in paraconsistent topological models.     

Motivational enhancement treatment in outpatient addiction centers: A multisite randomized trial

Background/Objectives: Motivational Enhancement Treatment in Spanish (METS) is a brief intervention aimed at resolving patient ambivalence towards behavior change that has demonstrated efficacy in substance use disorder treatment to reduce use and increase treatment engagement in different populations. In order to have evidence for its implementation in Mexico, a multi-site, randomized, two-arm, controlled clinical trial was conducted at three outpatient addiction treatment centers in the country to compare the effect of METS with Counseling as Usual (CAU). Method: One hundred and twenty patients were randomized to receive three sessions of METS (n = 54) or CAU (n = 66) during the first four weeks of treatment and were assessed during the following 12 weeks. Primary outcome measures were self-reported days of substance use and of treatment services utilization, which were tested using Generalized Estimating Equations. Results: Results associated both conditions with significant changes in substance use over, whereas there were no differences between conditions in substance use or in service utilization. Conclusions: Findings do not support the hypothesis that METS is more effective than CAU, but suggest that brief interventions at treatment initiation may improve patient outcomes.     

Screening for Eating Disorders in Undergraduate Women: Norms and Validity of the Spanish Version of the Eating Disorder Examination Questionnaire (EDE-Q)

The purpose of this investigation was to examine the internal consistency reliability and the convergent validity of the Spanish version of the Eating Disorder Examination Questionnaire (EDE-Q) and to provide EDE-Q norms for Spanish undergraduate women. Seven hundred eight college women, aged 18–30 years, volunteered to complete the EDE-Q, BSQ and EDI-2. Satisfactory internal consistency for the four subscales and the global score of the EDE-Q was obtained (Cronbach’s α ≥ .81). The EDI-2 Drive for Thinness and Body Dissatisfaction subscales and the BSQ global factor score correlated highly and positively with the corresponding EDE-Q subscales (r ≥ .72). Average scores, standard deviations and percentile ranks for the raw EDE-Q subscales and data on the occurrence of binge eating and compensatory behaviors are presented. Most of these values were lower than those found in other non-European developed countries. Results support the satisfactory internal consistency and convergent validity of the Spanish version of the EDE-Q. Lower scores in EDE-Q subscales suggest the need to study a lower cut-off point for clinical significance in Spanish college women. These data will help clinicians and researchers to interpret the EDE-Q scores of college women in Spain.     

The evolution of alexia in two cases of posterior cortical atrophy

Posterior cortical atrophy (PCA) is an uncommon presentation of Alzheimer's disease (AD), characterised by prevalent anatomo-functional involvement of posterior cortical areas. Accordingly, the main clinical features at onset are disorders of high-order visual processing, such as alexia and impairments of visuo-spatial and visuo-constructional abilities. The clinical features in the early stages of disease are variable, and they have been suggested to stem from prevalent ventral or dorsal brain pathology, and/or asymmetric hemispheric involvement. With disease progression, these differences tend to blur with the increasing severity of neuropsychological dysfunction. We report two PCA patients showing different patterns of reading impairment (respectively, letter-by-letter reading and neglect dyslexia). A follow-up study suggested that the qualitative features of alexia remain distinctive with disease evolution. In addition, single photon emission tomography (SPECT) studies revealed different patterns of hypoperfusion, consistent with the alexia types. A careful reading assessment can provide important insights to the pattern of progression of the disease in patients with PCA up to the late stages of the pathology.
