Ambivalence resolution in emotion-focused therapy: The successful case of Sarah

Ambivalence can be understood as a cyclical movement between two opposing positions of the self: one expressed in a novelty—an innovative moment (IM)—and another one conveyed by a return to the maladaptive pattern. If not properly addressed and resolved during therapy, ambivalence can prevent change and lead to psychotherapeutic failure. Two processes of ambivalence resolution have been suggested: (1) the dominance of the innovative position and consequent inhibition of the problematic position and (2) the negotiation between both positions. Objectives: To empirically study both processes of ambivalence resolution in a successful case of emotion-focused therapy. Method: Sessions were independently coded with three coding systems—the IMs, the return to the problem and the ambivalence resolution. Results: Ambivalence tended to be resolved from the initial to the final sessions. Although resolutions through dominance tended to decrease and resolutions through negotiation seemingly increased along treatment, dominance was, nonetheless, the most prominent process of resolution along the whole treatment. Conclusions: Although it has been suggested that integrating opposing parts of the self is a necessary process for psychotherapeutic success, a less integrative process of ambivalence resolution may also be an important resource along the process.Portuguese Foundation for Science and Technology and the Portuguese Ministry of Science, Technology and Higher Education through national funds and co-financed by FEDER through COMPETE2020 under the PT2020 Part- nership Agreement (POCI-01-0145-FEDER-007653

Maize IgE binding proteins: each plant a different profile?

Background: Allergies are nearly always triggered by protein molecules and the majority of individuals with documented immunologic reactions to foods exhibit IgE hypersensitivity reactions. In this study we aimed to understand if natural differences, at proteomic level, between maize populations, may induce different IgE binding proteins profiles among maize-allergic individuals. We also intended to deepen our knowledge on maize IgE binding proteins. Results: In order to accomplish this goal we have used proteomic tools (SDS-PAGE and 2-D gel electrophoresis followed by western blot) and tested plasma IgE reactivity from four maize-allergic individuals against four different protein fractions (albumins, globulins, glutelins and prolamins) of three different maize cultivars. We have observed that maize cultivars have different proteomes that result in different IgE binding proteins profiles when tested against plasma from maize-allergic individuals. We could identify 19 different maize IgE binding proteins, 11 of which were unknown to date. Moreover, we found that most (89.5%) of the 19 identified potential maize allergens could be related to plant stress. Conclusions: These results lead us to conclude that, within each species, plant allergenic potential varies with genotype. Moreover, considering the stress-related IgE binding proteins identified, we hypothesise that the environment, particularly stress conditions, may alter IgE binding protein profiles of plant components

Interplay between the salience and the default mode network in a social-cognitive task toward a close other

Social cognition relies on two main subsystems to construct the understanding of others, which are sustained by different social brain networks. One of these social networks is the default mode network (DMN) associated with the socio-cognitive subsystem (i.e., mentalizing), and the other is the salience network (SN) associated with the socio-affective route (i.e., empathy). The DMN and the SN are well-known resting state networks that seem to constitute a baseline for the performance of social tasks. We aimed to investigate both networks' functional connectivity (FC) pattern in the transition from resting state to social task performance. A sample of 38 participants involved in a monogamous romantic relationship completed a questionnaire of dyadic empathy and underwent an fMRI protocol that included a resting state acquisition followed by a task in which subjects watched emotional videos of their romantic partner and elaborated on their partner's (Other condition) or on their own experience (Self condition). Independent component and ROI-to-ROI correlation analysis were used to assess alterations in task-independent (Rest condition) and task-dependent (Self and Other conditions) FC. We found that the spatial FC maps of the DMN and SN evidenced the traditional regions associated with these networks in the three conditions. Anterior and posterior DMN regions exhibited increased FC during the social task performance compared to resting state. The Other condition revealed a more limited SN's connectivity in comparison to the Self and Rest conditions. The results revealed an interplay between the main nodes of the DMN and the core regions of the SN, particularly evident in the Self and Other conditions.info:eu-repo/semantics/publishedVersio

CNV Characterization, Inheritance and Phenotypic Correlations in Families With Autism

Autism Spectrum Disorders (ASD) have a strong genetic component, with an estimated heritability of over 90%1. Recent studies carried out by the Autism Genome Project (AGP) consortium suggest that rare Copy Number Variants (CNVs), characterized by submicroscopic chromosomal deletions and duplications, are more frequent in ASD compared to controls, and may play an important role in susceptibility to this disorder2. However, to adequately assess pathogenicity, a detailed characterization of patients CNVs and phenotype is required. The goal of this study was to establish the clinical and etiological relevance for ASD of potentially pathogenic CNVs identified in a Portuguese population sample by whole genome CNV analysis, through the detailed characterization of CNVs and correlation with clinical phenotypes. Analysis of the AGP genome-wide CNV results using 1M SNP microarray2 identified a total of 14218 CNVs in 342 Portuguese probands. We selected 291 CNVs, present in 191 individuals (19 females and 172 males), using the following criteria: 1) CNVs that contained implicated/candidate genes for ASD; 2) CNVs in genomic regions known to be implicated/candidate for ASD; 3) CNVs in regions associated with syndromes with ASD symptoms; and 4) high confidence CNVs that did not overlap more than 20% with controls in available databases. We explored recurrence rates, genic content, regulatory elements, inheritance patterns and phenotypic correlations.This work was supported by the fellowships SFRH/BPD/74739/2010 to ICC, SFRH/BPD/64281/2009 to CC and SFRH/BD/79081/2011 to BO from Fundação para a Ciência e a Tecnologia (Portugal)

Limited Evidence of an Association Between Language, Literacy, and Procedural Learning in Typical and Atypical Development : A Meta-Analysis

The ability to extract patterns from sensory input across time and space is thought to underlie the development and acquisition of language and literacy skills, particularly the subdomains marked by the learning of probabilistic knowledge. Thus, impairments in procedural learning are hypothesized to underlie neurodevelopmental disorders, such as dyslexia and developmental language disorder. In the present meta-analysis, comprising 2396 participants from 39 independent studies, the continuous relationship between language, literacy, and procedural learning on the Serial Reaction Time task (SRTT) was assessed across children and adults with typical development (TD), dyslexia, and Developmental Language Disorder (DLD). Despite a significant, but very small, relationship between procedural learning and overall language and literacy measures, this pattern was not observed at the group-level when examining TD, dyslexic, and DLD groups separately. Based on the procedural/declarative model, a positive relationship was expected between procedural learning and language and literacy measures for the typically developing group; however, no such relationship was observed. This was also the case for the disordered groups (ps > .05). Also counter to expectations, the magnitude of the relationship between procedural learning and grammar and phonology did not differ between TD and DLD (ps > .05), nor between the TD and dyslexic group on reading, spelling, and phonology (ps > .05). While lending little support to the procedural/declarative model, we consider that these results may be the consequence of poor psychometric properties of the SRTT as a measure of procedural learning

The reliability of the serial reaction time task : meta-analysis of test-retest correlations

The Serial Reaction Time task, one of the most widely used tasks to index procedural memory, has been increasingly employed in individual differences research examining the role of procedural memory in language and other cognitive abilities. Yet, despite consistently producing robust procedural learning effects at the group level (i.e. faster responses to sequenced/probable trials versus random/improbable trials), these effects have recently been found to have poor reliability. In this meta-analysis ( N = 7), comprising 719 participants ( M = 20.81, s.d. = 7.13), we confirm this 'reliability paradox'. The overall retest reliability of the robust procedural learning effect elicited by the SRTT was found to be well below acceptable psychometric standards ( r < 0.40). However, split-half reliability within a session is better, with an overall estimate of 0.66. There were no significant effects of sampling (participants' age), methodology (e.g. number of trials, sequence type) and analytical decisions (whether all trials were included when computing the procedural learning scores; using different indexes of procedural learning). Thus, despite producing robust effects at the group-level, until we have a better understanding of the factors that improve the reliability of this task using the SRTT for individual differences research should be done with caution

Career adaptability in portuguese adolescents

Revista de Psicologia da Criança e do Adolescente. - ISSN 1647-4120. - V. 10, n. 2 (2019).- p. 67-74.A adaptabilidade de carreira inclui a preocupação positiva com o futuro, a confiança na resolução de transições vocacionais, a curiosidade sobre o mundo escolar e profissional e a perceção de controlo sobre o futuro. Estas atitudes podem favorecer o planeamento, a autoeficácia, a exploração e a decisão de carreira, comportamentos importantes para a construção de identidade e o sucesso educativo, na adolescência. Neste estudo, com base na Escala sobre Adaptabilidade, analisou-se o perfil de adaptabilidade de carreira de 349 estudantes do 9º ano (184 rapazes, 52,7%, Midade=14,55, DP=0,90) a estudarem em três regiões do norte do país. Os adolescentes apresentaram níveis positivos de confiança, controlo, curiosidade e preocupação, respetivamente. Verificaram-se diferenças significativas entre sexos, com as alunas a pontuar mais elevado do que os rapazes na preocupação e os rapazes a pontuar mais elevado do que as raparigas na confiança, curiosidade e controlo percebidos sobre a carreira. Não se registaram diferenças entre alunos mais novos e mais velhos. Os alunos de uma região menos interior registaram níveis de confiança em relação à resolução de problemas e transições de carreira significativamente mais elevados, quando comparados com os da região mais interior. As intervenções de carreira em contexto escolar planeadas para esta região poderão ser informadas por resultados como estes.Career adaptability includes positive concern about the future, confidence in coping with career transitions, curiosity about educational and occupational worlds, and perceived control over the future. These attitudes may favor planning, self-efficacy, career exploration and decision making, important behaviors for identity construction and educational success in adolescence. In this study, based on the Adapt-ability Scale, we analyzed the career adaptability profile of 349 9th grade students (184 boys, 52.7%, Mage = 14.55, SD = .90) attending schools in three northern regions from the country. Adolescents presented positive levels of confidence, control, curiosity and concern, respectively. There were significant differences between sexes, with girls scoring higher than boys in concern, and boys scoring higher than girls in perceived confidence, curiosity and control over their careers. There were no differences between younger and older students. Students from a less inland region experienced significantly higher levels of confidence in problem solving and career transitions when compared to those in the innermost region. Career interventions in school settings planned for this region may be informed by results such as these

Relevance of Common and Rare CNVs for Autism Etiology

Recent reports by the Autism Genome Project (AGP) consortium and other groups show that Copy Number Variants (CNVs), while individually rare, collectively may explain a large fraction of the etiology of Autism Spectrum Disorders (ASD).

A single-phase current-source converter combined with a hybrid converter for interfacing an electric vehicle and a renewable energy source

This paper presents a single-phase current-source converter (CSC) combined with a hybrid converter on the dc-link, allowing to interface an electric vehicle (EV) and a renewable energy source (RES). Therefore, the interface with the power grid is only performed through the CSC, which also permits the operation as shunt active power filter (SAPF), allowing to compensate power quality problems related with current and low power factor in the electrical installation. The whole system is composed by two main power stages, namely, the CSC that is responsible for compensating the current harmonics and low power factor, as well as operating as a grid-tied inverter or as an active rectifier, and the hybrid converter that is responsible for interfacing the dc-link of the CSC with the converters for the EV and the RES interfaces. As demonstrated along the paper, the CSC, combined with the hybrid converter on the dc-link, allows the operation as SAPF, as well as the operation in bidirectional mode, specifically for the EV operation, and also for injecting power from the RES. In the paper, the power electronics structure is described and the principle of operation is introduced, supported by the description of the control algorithms. The validation results show the proper operation of the CSC, combined with the hybrid converter on the dc-link, for the main conditions of operation, namely exchanging power with the power grid in bidirectional mode and operating as a SAPF.This work has been supported by FCT – Fundação para a Ciência e Tecnologia with-in the Project Scope: UIDB/00319/2020.
