The COVID-19 outbreak required diverse strategies, such as social distancing and self-isolation, to avoid a healthcare system crisis. However, these measures have been associated with the onset or increase of anxiety and depression symptoms in the population. Music listening was previously shown to regulate emotion, consequently reducing depression symptoms. Since previous studies with Brazilian samples have already shown a high prevalence of depressive symptoms during the first confinement period, the aim of this study was threefold: (i) to compare groups with severe depression symptoms and no depression in what concerns to demographic and socio-economic factors as well as symptoms of anxiety and resilience levels, (ii) to explore changes in music listening daily routine during the confinement measures by both groups (no depression and severe depression), and (iii) to investigate which were the main factors influencing both two groups to music listening during the COVID-19 pandemic. This cross-sectional study included 494 Brazilian respondents aged 18 years and above. Our online survey comprised demographics, socio-economic, and COVID-19 related questionnaires, with questions regarding music listening used during social distancing measures on which the participants rated how much each of the 41 potential reasons for listening to music changed in importance compared to the situation before the pandemic and also the evaluation of anxiety, depression, and resilience levels. The respondents with severe depression were younger and showed higher levels of anxiety symptoms and lower resilience level. Furthermore, they were increasingly likely to listen to music to feel emotionally better with the situation, to feel comfort, to forget problems, to be energetic, to decrease sad feelings, to relax, to cheer up, to forget concerns, to express feelings, to reduce anxiety, to remember better times, to relieve boredom, to mentally stimulate themselves, and to ward off stressful thoughts compared to the participants with no depression. The exploratory factor analysis (FA) identified four types of music listening functions during social distancing measures: negative mood management, cognitive functioning, positive mood management, and physical involvement, in which the participants with severe depression revealed significant differences compared to non-depressed participants for the negative mood management factor, which shows the importance of music listening to regulate their negative emotions. As a conclusion, we can argue that most of our respondents used music listening to cope with and regulate their moods during confinement, especially those who presented with severe depression symptoms.
The effects of the COVID-19 pandemic have required substantial adjustments in terms of university teaching–learning processes. The aim of this study was to verify whether there were significant differences between the academic year of 2020 and the two preceding years in factors and symptoms and stress. A total of 642 university students (ages 18–25 years) participated by filling out validated self-reports during the months from March to August 2020. Using an ex post facto design, SEM analyses and simple and multiple ANOVAs were performed. Structural results showed that stress factors from the teaching process had a predictive value for the learning process, emotions, and academic burnout, and being a man was a factor predicting negative emotion. In a similar way, inferential results revealed no significant effect of academic year but did show an effect of gender on stress experiences during the pandemic. Aside from certain specific aspects, there was no significant global effect of the year 2020 on factors and symptoms of stress. The results showed that studying in the year of the COVID-19 outbreak did not have a significant effect on stress triggered by the teaching process. From these results, we draw implications for specific guidance interventions with university teachers and students.
RESUMO -O presente estudo investigou aspectos da representação numérica (processamento numérico e cálculo) e memória operacional de crianças com transtornos de aprendizagem. Participaram 30 crianças de idade entre 9 e 10 anos, ambos os gêneros, divididas em dois grupos: sem dificuldade em aritmética (SDA; N=11) e com dificuldade em aritmética (CDA; N=19), avaliadas pela ZAREKI-R, Matrizes Coloridas de Raven, o Blocos de Corsi e o BCPR. Crianças CDA exibiram escores levemente mais baixos que as SDA quanto ao nível intelectual e nos Blocos de Corsi. Na ZAREKI-R apresentaram prejuízo nos subtestes ditado de números, cálculo mental, problemas aritméticos e total. Crianças CDA apresentaram déficits específicos em memória operacional visuoespacial e comprometimento em processamento numérico e cálculo, compatível com discalculia do desenvolvimento.Palavras-chave: Discalculia do Desenvolvimento; Matemática; Memória Operacional; Neuropsicologia; Transtornos de Aprendizagem.Developmental Dyscalculia: Assessment of Number Representation by the ZAREKI-R ABSTRACT -This study investigated which aspects of number processing and calculation and working memory are related to arithmetic deficits. The participants were children aged from 9 to 10 years, both gender, divided in two groups based on their calculation score: a group without arithmetic disability (SDA; N=11) and with arithmetic disability (CDA; N=19); assessed by the instruments: ZAREKI-R, Raven's Coloured Progressive Matrices, Block Span, Digit Span, and BCPR (pseudowords repetition). CDA children exhibited slightly lower scores than SDA on intellectual level and Block Span, and deficits in dictation of numbers, mental calculation, and problem solving tasks of the ZAREKI-R. The results indicate that CDA children have specific deficits in visuospatial working memory and performed poorly in number representation tasks, which fulfill criteria for Developmental Dyscalculia.Keywords: Developmental Dyscalculia; Mathematic; Working memory; Neuropsychology; learning disabilities. Há uma capacidade inata para habilidades quantitativas que inclui uma compreensão implícita de numerosidade, ordinalidade, contagem e aritmética simples (Geary, 1995), a qual constitui um modo de processamento não simbólico de quantidades, baseado em subtização e aproximação (Feigenson, Dehaene & Spelke, 2004). Essa capacidade se desenvolve gradualmente no decorrer dos anos pré-escolares, juntamente com a linguagem e sua estruturação (Geary, 2000). Com a inserção no Ensino Fundamental, as crianças aprendem a representar os números por meio do processamento simbó-lico (p.ex., palavras, numerais, ideogramas), o que permite a manipulação e comparação de quantidades precisas (Mundy & Gilmore, 2009). Uma vez que as habilidades quantitativas adquirem características culturais (Geary, 2000;von Aster & Shalev, 2007), fatores linguísticos, culturais e pedagógicos têm diferentes efeitos nos diversos componentes das habilidades matemáticas e podem, em alguns casos, afetar a aprendizagem escolar (Dellatolas, von ...
In this review, we investigated the influence of happy/pleasurable and sad/unpleasant emotional stimuli on working memory (WM) performance. Twenty-eight out of 356 articles were reviewed. We observed that emotional stimuli were used as mood inductors or as targets comprising the WM task. Results showed that WM modalities were influenced differently when updating, interference resolution, span, and complex tasks were applied. Specifically, we found distinct effects of emotional stimuli for updating tasks, in which (a) verbal modality seems to be impaired regardless of the emotional valence used compared to neutral stimuli, (b) visual updating processes appear to be improved by emotional stimuli as the targets of the task, and (c) emotional words improved interference resolution performance. As for storage, span, and complex WM tasks, sad/unpleasant emotional stimuli seem to decrease both verbal and visuospatial modalities when used as emotional inductors.

In a population of young adults, this study analyzes possible linear relations of resilience and positivity to coping strategies and engagement-burnout. The aim was to establish a model with linear, associative, and predictive relations, to identify needs and make proposals for therapeutic intervention in different student profiles. A population of 1,126 undergraduate students with different student profiles gave their informed, written consent, and completed validated questionnaires (CD-RISC Scale; Positivity; Coping Strategies of Stress; Engagement, and Burnout). An ex post-facto design involved bivariate association analyses, multiple regression and structural predictions. The results offered evidence of associations and predictive relationships between resilience factors, positivity, coping strategies and engagement-burnout. The factors of resilience and positivity had significant differential associations (positive and negative) with factors of coping strategies. Their negative relationship to burnout factors, and positive relation to engagement factors, is especially important. Results of structural analysis showed an acceptable model of relationships between variables. We conclude with practical implications for therapeutic intervention: (1) the proactive factors of resilience reflect a perception of self-efficacy and the ability to change adaptively; (2) the reactive factors of resilience are usually associated with withstanding experiences of change, uncertainty or trauma.
Math Anxiety (MA) is characterized by a negative emotional response when facing math-related situations. MA is distinct from general anxiety and can emerge during primary education. Prior studies typically comprise adults and comparisons between high- versus low-MA, where neuroimaging work has focused on differences in network activation between groups when completing numerical tasks. The present study used voxel-based morphometry (VBM) to identify the structural brain correlates of MA in a sample of 79 healthy children aged 7–12 years. Given that MA is thought to develop in later primary education, the study focused on the level of MA, rather than categorically defining its presence. Using a battery of cognitive- and numerical-function tasks, we identified that increased MA was associated with reduced attention, working memory and math achievement. VBM highlighted that increased MA was associated with reduced grey matter in the left anterior intraparietal sulcus. This region was also associated with attention, suggesting that baseline differences in morphology may underpin attentional differences. Future studies should clarify whether poorer attentional capacity due to reduced grey matter density results in the later emergence of MA. Further, our data highlight the role of working memory in propagating reduced math achievement in children with higher MA.
