Within journalism, it generates revulsion, attraction, and, especially, uncertainties about its real function. What seems incontestable, however, is its constant rhetorical use in the construction of discourses. In this present research, we must investigate the discursive construction of the concept of football rivalry through emotions. In particular, the use of Schadenfreude, the joy with other's failure, as a constituent element of sports narratives. As an object, we will look at the "cheering narratives" of the Gremista GZH and Colorado GZH applications, where journalists stand next to the audience to whom they direct their messages, as opposed to conventional radio and press narration. For this investigation, Discourse Analysis (AD), based on the concepts of Charaudeau (2004a; 2004b; 2015) and P?cheux (1990; 1995), will be adopted as a procedure in order to identify discursive visions, the addressee idealized by the enunciator and references to the rival. As a methodology, Depth Hermeneutics (HP) will be adopted as assigned by Thompson (2011). This work is based on the journalistic concepts of McCombs (2009), Traquina (2000; 2008) and Wolf (2012), socialsports of Caillois (1990), Damo (2002; 2015), Elias and Dunning (2000), Helal (1990, 1997, 2001) and Huizinga (2010), and psycho-socio-anthropological about Emotion of Dam?sio (2000), Ekman (2011), and Rezende and Coelho (2010). / A emo??o deixou de ser um conceito marginal para ocupar boa parte da literatura recente na Comunica??o Social. Dentro do jornalismo, ela gera repulsa, atra??o e, especialmente, incertezas sobre sua real fun??o. O que nos parece inconteste, entretanto, ? seu constante uso ret?rico na constru??o de discursos. Nesta presente pesquisa, cabe-nos investigar a constru??o discursiva do conceito de rivalidade no futebol por meio das emo??es. Em particular, o emprego da Schadenfreude, o regozijo com o insucesso alheio, como elemento constitutivo das narrativas esportivas. Como objeto, analisaremos as ?narra??es torcedoras? dos aplicativos Gremista Ga?cha ZH e Colorado Ga?cha ZH, nas quais os jornalistas se posicionam ao lado do p?blico ao qual direcionam suas mensagens, em oposi??o ? narra??o convencional do r?dio e da imprensa. Para esta investiga??o, ser? adotado como procedimento a An?lise de Discurso (AD), baseada nos conceitos de Charaudeau (2004a; 2004b; 2015) e P?cheux (1990; 1995), com o intuito de identificar as visadas discursivas, o destinat?rio idealizado pelo enunciador e as refer?ncias ao rival. Como metodologia, ser? adotada a Hermen?utica de Profundidade (HP) conforme as designa??es de Thompson (2011). Este trabalho fundamenta-se ainda nos conceitos jornal?sticos de McCombs (2009), Traquina (2000; 2008) e Wolf (2012), s?cio-esportivos de Caillois (1990), Damo (2002; 2015), Elias e Dunning (1992), Franco J?nior (2007), Giulianotti (2010), Helal (1990; 1997; 2001) e Huizinga (2010), e psico-s?cio-antropol?gicos sobre emo??o de Dam?sio (2000), Ekman (2011) e Rezende e Coelho (2010).

Dentre as escalas mais estudadas,est? a que abrange o arranjo de segundos a minutos. Evid?ncias sugerem que o c?rtex pr?-frontal dorsolateral (CPFDL) possui rela??o com a percep??o do tempo na escala de segundos. No entanto, n?o se sabe se o d?ficit de percep??o temporal em pacientes com les?es cerebrais ou mesmo ?les?es revers?veis? causadas por estimula??o magn?tica transcraniana (EMT) nessa regi?o, sejam por perturba??es de outros processos cognitivos (como aten??o e mem?ria de trabalho) ou da percep??o do tempo propriamente dita. Estudos tamb?m relacionam a regi?o do CPFDL na regula??o emocional e especificamente no julgamento e a antecipa??o emocional. Diante disto, nosso objetivo foi estudar o papel do c?rtex pr?-frontal dorsolateral na percep??o de intervalos de tempo de est?mulos neutros e emocionalmente ativos, a partir dos efeitos da modula??o cortical atrav?s da estimula??o transcraniana por corrente cont?nua (ETCC), atrav?s da excita??o (corrente an?dica), inibi??o (corrente cat?dica) e o controle (sham), utilizando os intervalos de 4 e 8 segundos. Nossos resultados mostraram que h? uma subestimativa quando a figura ? apresentada por 8 segundos.Com a corrente an?dica no CPFDL direito ocorre uma subestimativa e com a corrente cat?dica no CPFDL esquerdo h? uma superestimava na reprodu??o do tempo com figuras neutras. Com figuras negativas, a corrente cat?dica sobre o CPFDL esquerdo ocasiona efeito inverso ao de figuras neutras, havendo subestimativa de tempo. O uso de figuras com val?ncia positiva ou negativa, melhoraram as estimativas para 8 segundas e o uso de figuras com val?ncia positiva inibem o efeito da ETCC no CPFDL na estimativa de tempo para 4 segundos. Com esse trabalho podemos concluir que o CPFDL tem um papel fundamental na percep??o de tempo e corresponde em grande parte aos est?gios de mem?ria e decis?o no modelo de rel?gio interno, que o hemisf?rio esquerdo participa na percep??o de tempo tanto em contextos neutros como emocionalmente ativos, Podemos concluir tamb?m que a ETCC e um m?todo eficaz para estudar as fun??es corticais na percep??o de tempo em termos de causa e efeito. / The time perception is critical for environmental adaptation in humans and other species. The temporal processing, has evolved through different neural systems, each responsible for processing different time scales. Among the most studied scales is that spans the arrangement of seconds to minutes. Evidence suggests that the dorsolateral prefrontal (DLPFC) cortex has relationship with the time perception scale of seconds. However, it is unclear whether the deficit of time perception in patients with brain injuries or even "reversible lesions" caused by transcranial magnetic stimulation (TMS) in this region, whether by disruption of other cognitive processes (such as attention and working memory) or the time perception itself. Studies also link the region of DLPFC in emotional regulation and specifically the judgment and emotional anticipation. Given this, our objective was to study the role of the dorsolateral prefrontal cortex in the time perception intervals of active and emotionally neutral stimuli, from the effects of cortical modulation by transcranial direct current stimulation (tDCS), through the cortical excitation (anodic current), inhibition (cathode current) and control (sham) using the ranges of 4 and 8 seconds. Our results showed that there is an underestimation when the picture was presented by 8 seconds, with the anodic current in the right DLPFC, there is an underestimation and with cathodic current in the left DLPFC, there is an overestimation of the time reproduction with neutral ones. The cathodic current over the left DLPFC leads to an inverse effect of neutral ones, an underestimation of time with negative pictures. Positive or negative pictures improved estimates for 8 second and positive pictures inhibited the effect of tDCS in DLPFC in estimating time to 4 seconds. With this work, we conclude that the DLPFC plays a key role in the o time perception and largely corresponds to the stages of memory and decision on the internal clock model. The left hemisphere participates in the perception of time in both active and emotionally neutral contexts, and we can conclude that the ETCC and an effective method to study the cortical functions in the time perception in terms of cause and effect.

An example of emotional item that benefits declarative memory processes are the taboo words. These words undergo from a conventional prohibition, imposed by tradition or custom. Literature suggests that the strongest recollection these words is due to emotional arousal, as well as, the fact that they form a cohesive semantic group, which is a positive additive effect. However, studies with semantic lists show that cohesion can have a negative effect of interference, impairing memory. We analyzed, in two experiments, the effect of arousal and semantic cohesion of taboo words on recognition tests, comparing with into two other word categories: semantically related and without emotional arousal (semantic category) and neutral, with low semantic relation (objects). Our results indicate that cohesion has interfered whith the performance of the test by increasing the number of false alarms. This effect was strongly observed in the semantic category of words in both experiments, but also in the neutral and taboo words, when both were explicitly considered as semantic categories through the instruction of the test in Experiment 2. Despite the impairment induced by semantic cohesion in both experiments, the taboo words were more discriminated than others, and this result agrees with the indication of the emotional arousal as the main factor for the best recollection of emotional items in memory tests / Itens com alto grau de alerta emocional s?o melhor recordados em tarefas de mem?ria do que itens neutros. Um tipo de item emocional que beneficia os processos de mem?ria declarativa s?o as palavras tabus. Estas s?o palavras que sofrem uma proibi??o convencional imposta por tradi??o ou costume. A literatura sugere que o melhor desempenho destas palavras ? devido ao alerta emocional e tamb?m ao fato de formarem um grupo sem?ntico coeso, constituindo um efeito positivo aditivo. Entretanto, estudos com listas sem?nticas apontam que a coes?o pode produzir um efeito negativo de interfer?ncia, prejudicando a recorda??o. Analisamos, em dois experimentos, o efeito do alerta e da coes?o sem?ntica de palavras tabus em testes de reconhecimento, comparando com palavras agrupadas em duas outras categorias: com rela??o sem?ntica e sem alerta (categoria sem?ntica) e neutras ou com pouca rela??o sem?ntica (categoria objetos). Nossos resultados apontaram que a coes?o prejudicou o desempenho no teste por aumentar o n?mero de alarmes falsos. Esse efeito foi fortemente observado nas palavras da categoria sem?ntica em ambos os experimentos, mas tamb?m nas palavras tabus e nas neutras, quando ambas foram explicitamente consideradas como categorias sem?nticas por meio da instru??o do teste do experimento 2. Apesar do preju?zo da coes?o sem?ntica, em ambos os experimentos as palavras tabus foram mais discriminadas do que as demais e esse resultado concorda com a indica??o do alerta emocional como principal fator para o melhor desempenho de itens emocionais em testes de mem?ria

Por?m, ainda n?o ? claro como o conte?do emocional associado a uma determinada via sensorial pode afetar o processamento de outras modalidades sensoriais. O objetivo deste estudo foi avaliar como as imagens com conte?do emocional influenciam o processamento sensorial auditivo, atrav?s do potencial evocado auditivo de um som in?cuo. Para isso, foi registrado o potencial evocado auditivo em 36 estudantes universit?rios durante a apresenta??o de blocos de imagens negativas, blocos de imagens positivas, blocos de imagens neutras ou uma tela em branco. Analisamos tamb?m os escores de val?ncia e alerta das imagens, a variabilidade da frequ?ncia card?aca e a pot?ncia das bandas de frequ?ncia teta e alfa,. As imagens negativas, positivas e neutras tiveram os escores de val?ncia e alerta esperado para esses tipos de imagens, mas esses resultados diferiram dos escores da padroniza??o realizada para o Brasil. J? na variabilidade da frequ?ncia card?aca, foi observada uma desacelera??o do ritmo card?aco durante a apresenta??o das imagens negativas e positivas, o que correlacionou com os escores das imagens. Quanto ao potencial evocado auditivo, n?o encontramos um efeito da emo??o. Contudo, foi encontrada uma diminui??o da amplitude do potencial evocado durante a apresenta??o das imagens, independentemente da sua val?ncia. As an?lises das bandas de frequ?ncias mostraram um aumento da pot?ncia de teta e alfa no hemisf?rio esquerdo inicialmente durante as quatro condi??es. Em um segundo momento foi observado um aumento da pot?ncia dessas bandas durante a apresenta??o das imagens emocionais no hemisf?rio direito. Por ?ltimo, foi observada uma diminui??o da pot?ncia de teta no hemisf?rio direito na condi??o de imagens negativas. Os resultados da avalia??o das imagens e a variabilidade da frequ?ncia verificam que as imagens do International Affective Picture System (IAPS) s?o um bom m?todo para induzir e avaliar emo??es. Contudo, ? importante fazer uma melhor padroniza??o para todo o Brasil. A resposta do potencial evocado indica uma divis?o da orienta??o da aten??o entre as duas fontes de estimula??o. Por fim, o incremento da pot?ncia de teta e alfa principalmente no hemisf?rio direito, evid?ncia a import?ncia do hemisf?rio direito no processamento de informa??o sensorial. / Emotions are crucial for the survivor of the organisms. They allow individuals to recognize what is threatening and what is safe in the environment. Emotions work modulating several cognitive processes, such as perception, attention and memory. At an electrophysiological level, emotions influence the response of neuronal networks measured by Event-Related Potentials (ERP). It has been documented that pleasant and unpleasant pictures increase the amplitude of the visual ERP in the visual areas of the brain. However, little is known about how emotions affect the processing of stimuli of different sensory modalities. The aim of this work was to test how the International Affective Picture System (IAPS) may affect the ERP of an innocuous sound. For this purpose the auditory ERP of 36 healthy students was recorded while they were watching a stream of high arousal unpleasant, high arousal pleasant, neutral images or a white screen. Heart rate variability (HRV), subjective self-report and band frequency power were measured too. Results showed that subjective self-report of the pictures emotional property verified the emotional qualities of these pictures, but it was slightly different form the Brazilian standard scores. We also found a deceleration of the HRV during emotional pictures viewing, and this correlated with the subjective self-report. No effect from emotional valence on the auditory ERP was found, only an effect of the pictures when compared to the white screen condition. In the left hemisphere, band frequency power showed a increase of theta and alpha power in the first moment for the four conditions. In a second moment, there was a increase of the power of this two bands during emotional pictures presentation in the right hemisphere. And then, it was seen a decrease in the right hemisphere of theta band power during unpleasant picture viewing. Scores from the subjective self-report and HRV confirmed that IAPS are a good method to elicit and evaluate emotions, but is necessary to extend the Brazilian standardization to have a more reliable instrument. Findings in the auditory ERP suggest a division of attention between the two kind of stimulation. Finally, the increase in the theta and alpha band power, especially in the right hemisphere, throughout the temporal series suggest a specialization of right hemisphere in the processing of emotional information.

Os fatores ambientais que podem afetar o processamento facial e o reconhecimento emocional ao longo do curso de desenvolvimento tamb?m s?o pouco compreendidos. No entanto, acredita-se que as experi?ncias iniciais, particularmente envolvendo exposi??o repetida a faces emocionais dos cuidadores, influenciem esse curso. O objetivo deste estudo foi investigar os correlatos neurais do processamento de faces emocionais em lactentes usando a espectroscopia funcional no infravermelho pr?ximo (fNIRS), e examinar a poss?vel influ?ncia das experi?ncias emocionais iniciais dos lactentes, indiretamente medida pela investiga??o de sintomas de ansiedade materna. Foram avaliadas 29 crian?as de 5 meses de idade e suas m?es, recrutadas de uma amostra da comunidade de Boston, EUA. A ansiedade materna foi avaliada usando o componente tra?o do Invent?rio de Ansiedade Tra?o-Estado (STAI-T). Os lactentes observaram imagens visuais est?ticas de faces femininas retratando express?es de alegria e medo, enquanto as respostas hemodin?micas corticais foram medidas usando fNIRS. As respostas de oxihemoglobina (oxiHb) e deoxihemoglobina (deoxiHb) nas ?reas frontais, parietais e temporais foram comparadas entre as faces emocionais, e entre filhos de m?es com n?veis altos e baixos de sintomas de ansiedade. Os resultados demonstraram efeito principal significativo da emo??o (p=0,022), evidenciado pelo aumento na concentra??o de oxiHb para faces de alegria em compara??o a faces de medo. Ademais, observou-se efeito principal significativo da regi?o (p=0,013), induzido por maior concentra??o de oxiHb nas regi?es corticais temporais em rela??o ?s regi?es corticais frontais (p=0,031). Al?m disso, houve uma intera??o significativa entre emo??o, hemisf?rio e ansiedade (p=0,037). As an?lises revelaram que filhos de m?es com alta ansiedade demonstraram uma resposta hemodin?mica significativamente elevada no hemisf?rio esquerdo para faces de alegria, em compara??o com faces de medo no hemisf?rio direito (p=0,040) e esquerdo (p=0,033). Os resultados indicam que lactentes de 5 meses discriminaram faces de alegria em compara??o com faces de medo, evidenciado pela maior ativa??o para a primeira. A maior ativa??o nas regi?es temporais em rela??o ?s ?reas frontais foi discutida em rela??o ? ontog?nese do processamento facial e ?s redes neurais de reconhecimento emocional. A resposta mais acentuada, comparando faces de alegria e medo observada nos filhos de m?es com alta ansiedade, pode estar relacionada a altera??es no ambiente emocional dessas crian?as em compara??o com os filhos de m?es com baixa ansiedade. Assim, os n?veis de ansiedade materna parecem moderar as respostas cerebrais hemodin?micas das crian?as ?s faces emocionais. / The neural bases of facial emotion processing in infancy are largely unknown. The environmental factors that may impact facial processing and emotion recognition along the developmental course are also not clearly understood. However, early experiences, particularly involving consistent exposure to familiar caregiver faces, are believed to influence this course. The aim of this study was to investigate the neural correlates of infants? emotional face processing using functional near-infrared spectroscopy (fNIRS), and examine the potential influence of infants? early emotional experiences, indirectly measured by investigating maternal anxiety symptoms. Participants were 29 typically developing 5-monthold infants and their mothers, recruited from a community sample from the Boston greater area, MA, USA. Maternal anxiety was assessed using the trait component of the State-Trait Anxiety Inventory. Infants observed static visual images of a female model portraying happy and fearful expressions, while hemodynamic brain responses were measured using fNIRS. The oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb) responses over frontal, parietal and temporal areas were compared for the emotional expressions in infants of mothers reporting low and high levels of anxiety symptoms. Results revealed a significant main effect of emotion (p=.022), driven by greater oxyHb concentration responses for happy compared to fearful faces. There was also a main effect of region (p=.013) induced by a significantly greater oxyHb concentration in temporal compared to frontal cortical regions (p=.031). Additionally, a significant three-way interaction between emotion, hemisphere and anxiety was observed (p=.037). Planned comparisons revealed that infants of high-anxious mothers showed significantly greater left hemispheric activation of oxyHb to happy faces when compared with right (p=.040) and left (p=.033) hemispheric activation of oxyHb to fearful faces. These findings possibly indicate that 5-month-olds can discriminate happy from fearful faces, evinced by the greater activation for the former. The greater activation in temporal as compared to frontal areas was discussed in relation to the ontogenesis of face processing and emotion recognition neural networks. The enhanced response to happy versus fearful faces observed in infants of high-anxious mothers can be related to the presumed altered emotional environment experienced by these infants, compared to that of infants of low-anxious mothers. Therefore, maternal anxiety levels appeared to moderate infants? hemodynamic brain responses to emotional faces.

Estudo recen-tes tem sugerido que a pr?tica de pranayama est? associada a efeitos positivos sobre quadros de estresse e ansiedade. Esta tese tem por objetivo avaliar o impacto da pr?tica do Bhastrika Pranayama sobre marcadores de ansiedade, afeto, discurso e imagem funcional por resson?n-cia magn?tica (fMRI, Functional Magnetic Resonance Imaging) usando desenho controlado, randomizado de bra?os paralelos. Trinta adultos jovens saud?veis, e sem experi?ncia com o yoga, foram recrutados e avaliados por meio do invent?rio de ansiedade tra?o-estado (IDA-TE), da escala de afeto positivo e negativo (PANAS), da an?lise do discurso e da fMRI (tarefa de regula??o emocional, e resting state), antes e ap?s 4 semanas de pr?tica do Bhastrika Pra-nayama ou de atividades controle. Ap?s o treinamento observamos redu??o dos n?veis de an-siedade e de afeto negativo, e intera??o significativa no sinal da ?nsula anterior bilateral e c?n-gulo anterior direito. A an?lise de correla??o mostrou que ap?s a pr?tica do pranayama, os indiv?duos com maiores aumentos da atividade da am?gdala, e ?nsula bilateral foram os que menos reduziram o afeto negativo. Os dados de rs-fMRI revelaram redu??o significativa de conectividade funcional do c?rtex pr?-frontal ventrolateral (vlPFC) ? direita com c?rtex pr?-frontal dorsolateral (dlPFC) ? direita ap?s o treinamento. Correla??o entre dados de rs-fMRI e escala PANAS mostrou que entre os indiv?duos que fizeram o pranayama, os que mais reduzi-ram a conectividade entre ?nsula anterior ? direita com vlPFC bilateral foram os que mais re-duziram o afeto negativo. An?lise do discurso mostrou redu??o significativa na rela??o se-m?ntica entre os textos transcritos e a palavra ansiedade. N?o foram encontradas diferen?as nas estruturas do discurso. De forma geral, nossos resultados sugerem que a pr?tica do Bhas-trika Pranayama leva a mudan?as significativas de ansiedade e de afeto, que se mostraram acompanhadas por mudan?as na atividade e conectividade de estruturas cerebrais que partici-pam de processos de regula??o emocional. / The systematization of Yoga presented in the Yoga Sutras of Pata?jali, written around 400 CE, proposes an eight limb yoga system, also known as Ashtanga Yoga (ashta=eight, anga=limb), consisting of eight set of practices. Among them, the breathing practices, known as Pranayama, has been associated with positive effects on stress and anxiety. This thesis explores the impact of Bhastrika Pranayama training on markers of anxiety, affect, speech, and functional magnetic resonance imaging (fMRI) using a randomized controlled trial of two parallel arms. Thirty young healthy adults, na?ve to Yoga practices, were recruited and evalu-ated by the State-Trait Anxiety Inventory (STAI), the Positive and Negative Affect Schedule (PANAS), Speech Analysis and fMRI (emotional regulation task, and resting state-fMRI), before and after 4 weeks of training Bhastrika Pranayama or control activities. Results after bhastrika pranayama suggest reduction in both anxiety and negative affect, increased activity in bilateral anterior insula and right anterior cingulate cortex. Correlation analysis between fMRI signal during the emotional regulation protocol and PANAS scale showed that among individuals in pranayama group, individuals who most increased the activity in amygdala, right and left insula were those that less decreased negative affect. rs-fMRI results suggest decreased functional connectivity in the right ventrolateral prefrontal cortex (vlPFC) with right dorsolateral prefrontal cortex (dlPFC) after pranayama. Correlation between rs-fMRI data and PANAS scale showed that among individuals in pranayama group, those who most decreased the connectivity between right anterior insula with right and left vlPFC were the individuals that most decreased negative affect. Speech analysis showed reduction in semantic properties when the word ?anxiety? was used as seed. No significant difference was found in speech structures after pranayama. In general, our results suggest that the practice of Bhastrika Pranayama leads to changes in anxiety and affect, which was accompanied by changes in the activity and connectivity of brain structures that participate in processes of emotional regulation.

At the same time, the symbolic relations established between society and the cemetery contains interpretations about death, pain and fear which confer to the visits a special and individual feature. In this context, this dissertation tries to analyse the formation of a sociability observed among visitors of the Morada da Paz a private cemetery located in Natal/RN as well as the frequency of the visitors to the necropolis. Therefore, the research was accomplished from the observation of the existent relations among these actors whose meetings have procured links based on the experiences? exchange about pain and bereavement. In this sense, this study tries to analyse, as its principal point, in which way the Morada da Paz space and the relations established there are being appropriate by the visitors in their mourning process, trying to understand what are the role of these bond in the elaboration of the loss for these people / O estar enlutado, nos dias atuais, configura-se como uma circunst?ncia de isolamento e ang?stia social devido ? impossibilidade de exposi??o da dor por parte dos indiv?duos que sofrem uma perda. Ao mesmo tempo, a rela??o simb?lica institu?da entre a sociedade e o cemit?rio abrange interpreta??es sobre a morte, a dor e o medo conferindo ?s visitas ao espa?o um car?ter especial e individual. Diante deste contexto, esta disserta??o busca analisar a forma??o de uma sociabilidade observada entre visitantes do Morada da Paz - cemit?rio particular localizado em Natal/RN -, bem como a freq??ncia ass?dua destes sujeitos ? necr?pole. Assim, a pesquisa transcorre a partir da observa??o das rela??es existentes entre estes atores sociais - cujos encontros t?m proporcionado la?os baseados na troca de experi?ncias sobre a dor do luto. Desse modo, este estudo pretende analisar, como ponto principal, de que maneira o espa?o do Morada da Paz e as rela??es l? institu?das est?o sendo apropriados pelos visitantes em seu processo de luto, buscando compreender qual o papel destes v?nculos na elabora??o da perda para estes sujeitos

Its use has been related to higher therapeutic adhesion levels and well being sensation. Such emotional based aspects are often observed by subjective tools of relative validity. This study analyzed the immediate effects of varied VR contexts balance training over emotional behavior, which was observed under peaks of maximum expression of EEG waves. Methodology: 40 individuals, divided in two groups, both gender, 20 young and 20 elderly, were submitted to a 60 minutes intervention, including balance training under VR. The first 25 minutes referred to initial evaluation, general orientation and cognitive assessment by the use of Mini Mental. The next ten minutes were designated to the avatar creation and tutorial video presentation. Through the following 20 minutes, the individuals from both groups were exposed to the exact same sequence of games under virtual contexts, while submitted to electroencephalography by Emotiv EPOC? focusing Adhesion, Frustration and Meditation states. The virtual interface was provided by the Nintendo? game, Wii Fit Plus, with the scenarios Balance Bubble (1), Penguin (2), Soccer (3), Tight Rope (4) and Table Tilt (5). Finally, a questionnaire of personal impressions was applied on the 5 minutes left. Results: data collected showed 64,7% of individuals from both groups presented higher concentration of adhesion peaks on Balance Bubble game. Both groups also presented similar behavior regarding meditation state, with marks close to 40%, each, on the same game, Table Tilt. There was divergence related to the frustration state, being the maximum concentration for the young group on the Soccer game (29,3%), whilst the elderly group referred highest marks to Tight Rope game (35,2%). Conclusion: Findings suggest virtual contexts can be favorable to adhesion and meditation emotional patterns induction, regardless age and for both sexes, whilst frustration seems to be more related to cognitive motor affordance, likely to be influenced by age. This information is relevant and contributes to the orientation for the best choice of games applied in clinical practice, as for other studies regarding this topic / A associa??o de realidade virtual(RV) ? pr?tica cl?nica tem se mostrado comum nos ?ltimos anos, sendo mais uma ferramenta de aten??o ? sa?de, inclusive na terceira idade. Seu uso vem sendo relacionado a maiores ?ndices de ades?o terap?utica e bem estar, aspectos de base emocional frequentemente observados atrav?s de instrumentos subjetivos e de validade question?vel. O presente estudo analisou os efeitos imediatos do treino de equil?brio em contextos variados de RV sobre o comportamento emocional dos participantes, observado sob a forma de picos de express?o m?xima em ondas de EEG. Metodologia: 40 indiv?duos, de ambos os sexos, divididos em dois grupos, sendo 20 jovens e 20 idosos, realizaram ?nica interven??o de 60 minutos, incluindo treino em RV. Os primeiros 25 minutos abrangeram a avalia??o inicial, com orienta??es e aplica??o de instrumentos manuais (Ficha de avalia??o e Mini Mental). Dez minutos subsequentes foram designados ? cria??o do avatar e observa??o de v?deo tutorial pr? treino. Nos 20 minutos seguintes, os sujeitos de ambos os grupos foram expostos a uma sequ?ncia id?ntica de jogos em contextos virtuais, enquanto submetidos a eletroencefalografia por Emotiv EPOC? com foco em Ades?o, Frustra??o e Medita??o. A interface virtual foi proposta pelo jogo Wii Fit Plus, da Nintendo?, sendo usados os cen?rios Balance Bubble(1), Penguin(2), Soccer(3), Tight Rope(4) e Table Tilt(5). Finalmente, um question?rio de impress?es foi aplicado nos 5 minutos restantes. Resultados: os dados obtidos mostraram que 64,7% dos indiv?duos em ambos os grupos apresentaram maior concentra??o de picos m?ximos de ades?o no jogo Balance Bubble. Ambos os grupos tamb?m apresentaram comportamento semelhante em rela??o ao estado de medita??o, com ?ndices superiores a 40%, cada, no mesmo jogo, Table Tilt. Houve diverg?ncia sobre o estado de frustra??o, sendo o m?ximo do grupo jovem concentrado no jogo Soccer (29,4%), enquanto o grupo idoso manifestou tal emo??o mais intensamente no jogo Tight Rope (35,2%). Conclus?o: Os achados sugerem que contextos virtuais podem favorecer ? indu??o de padr?es emocionais de ades?o e medita??o independentemente de idade, ao passo que a frustra??o aparenta estar mais relacionada ao desempenho cognitivo motor, sendo aparentemente influenciada pelo avan?o senil. Estas informa??es s?o relevantes e passam a contribuir para a orienta??o da escolha adequada de jogos utilizados na pr?tica cl?nica atual

Tem por objetivo apontar como o entendimento proposto por esses autores pode configurar a constru??o de obras de dan?a contempor?nea e discutir poss?veis ferramentas de recupera??o de estados emocionais para a performance da obra investigada por meio de mapeamentos dos sentimentos de emo??es. Esta pesquisa tem como metodologia a an?lise qualitativa e processual da cria??o do Cinzas ao Solo, obra sol?stica apresentada pelo autor. O texto est? disposto da seguinte maneira: um primeiro cap?tulo introdut?rio ao tema das emo??es e sentimentos tratados nas artes da cena, mais especificamente na dan?a, com base nos olhares lan?ados ?s pr?prias emo??es e sentimentos por pesquisadores das ci?ncias da mente. Em seguida, ? apresentado o objeto da pesquisa: A investiga??o no modo como as emo??es e n?o somente suas express?es operaram em um processo de cria??o em dan?a. Logo, ? exposto o caminho metodol?gico que percorremos ao longo do escrito para, s? ent?o, serem anunciados os conceitos de emo??es e sentimentos de modo mais aprofundados e j? operacionalizados no cap?tulo II. No ?ltimo cap?tulo ? descrito como o jogo das emo??es se deu durante a cria??o da obra Cinzas ao Solo, o que compreende os momentos de Respiro, que s?o os instantes finais nos quais h? as apresenta??es p?blicas da obra em estudo. Por fim, trazemos as considera??es finais, tecidas junto a reflex?o gerada pela totalidade da experi?ncia da pesquisa art?stico-acad?mico. Nosso desejo ? que esse trajeto escrito possa contribuir para o laborar e refletir de outros artistas, uma vez que tentamos, durante o percurso investigativo, destramar alguns dos aspectos que consideramos mais importantes na feitura da dan?a c?nica: as emo??es e os sentimentos. o percurso anal?tico e reflexivo da urdidura da pe?a nos mostrou que as ferramentas de mapeamento sentimento-emocional se mostraram eficazes ao performar do bailarino. os estados de ?nimo conseguiram ser recuperados, atualizados no presente para um viver-dan?a inteiro e presentificado, que favorece o velejar nas paisagens infind?veis da cria??o. / The text presented here is the result of the theoretical-practical research of a master's thesis with the title Sentiment-Emotional Mapping of the Ashes to the Ground work: warps of a creation in dance. From the recurrent discussion of the performance of the emotions and their expressions in the Western scene, especially in contemporary times, it brings to light concepts derived from the cognitive sciences about emotion, feeling, and emotional feelings, addressed by scholars such as Antonio Dam?sio (2011) and Paul Ekman (2011). The purpose is to point out how the understanding proposed by these authors can configure the construction of contemporary dance works and discuss possible tools for the recovery of emotional states for the performance of the work investigated through mapping the feelings of emotions. This research has as methodology the qualitative and procedural analysis of the creation of Ashes to the Ground, a solo work presented by the author. The text is arranged as follows: a first introductory chapter to the theme of emotions and feelings treated in the arts of the scene, more specifically in dance, from the looks thrown to the own emotions and feelings by researchers of the sciences of the mind. Then the research object is presented: The investigation into the way the emotions and not only their expressions operated in a process of creation in dance. Therefore, the methodological path that we go through throughout the writing is exposed so that the concepts of emotions and feelings can be announced in a more detailed way already in operation in chapter II. In the last chapter it is described how the game of the emotions occurred during the creation of the Ashes to the Ground work, which comprises the moments of Respite, that are the final instants in which there are the public presentations of the work under study. Finally, we bring the final considerations, woven together with the reflection generated by the totality of the artistic-academic research experience. Our desire is that this written path can contribute to the work and reflection of other artists, since we try, during the entire investigative course, to shed light on some of the aspects that we consider most important in the making of the scenic dance: emotions and feelings. For surely, the more consciousness of the functioning of these mechanisms present in the body, the better we can sail in the endless landscapes of creation.

Estudos te?ricos prop?em o controle inibit?rio como elemento fundamental para a regula??o emocional de prazer durante o exerc?cio executado em diferentes intensidades. No entanto, ainda ? desconhecida a rela??o do controle inibit?rio com as respostas afetivas acerca da intensidade do exerc?cio. Objetivo: Verificar o efeito da intensidade do exerc?cio incremental m?ximo sobre o controle inibit?rio, afeto, controle auton?mico card?aco e oxigena??o do c?rtex pr?-frontal. M?todo: Trinta e sete adultos jovens, sedent?rios, participaram de forma randomizada de duas condi??es experimentais (controle e exerc?cio). Na condi??o exerc?cio, os participantes realizaram um teste incremental m?ximo em cicloerg?metro com concomitante e cont?nua a avalia??o da oxigena??o do CPF, variabilidade da frequ?ncia card?aca (VFV), controle inibit?rio (teste de stroop) e escalas de afeto e pensamento associativo e dissociativo (PAD). Na condi??o controle, os volunt?rios realizaram as mesmas avalia??es da condi??o exerc?cio, mas sem pedalar no cicloerg?metro. O par?metro de refer?ncia dos protocolos experimentais para a intensidade foi determinado pelo limiar ventilat?rio (LV). Foi utilizada a ANOVA two away para medidas repetidas com ajuste de Bonferroni, para comparar as condi??es (controle e exerc?cio) e os momentos (oito intensidades). Em seguida, foi realizada a correla??o de Pearson para verificar as correla??es do sentimento afetivo e controle inibit?rio com PAD, VFC e oxigena??o do CPF. Resultados: (I) a alta intensidade do exerc?cio promoveu decl?nio no controle inibit?rio, sentimento de desprazer, aumento da atividade simp?tica e oxigena??o CPF. (II) o incremento da intensidade promoveu correla??o entre o decl?nio do controle inibit?rio (maior n?mero de erro) com o aumento do PAD (r=0,77) e da oxigena??o CPF (DHb: r=0,87; Hbt: r=0,75). (III) o controle inibit?rio analisado pelo score efficience inverse, foi pior em alta e baixa intensidade quando comparada com seu comportamento na intensidade moderada Conclus?o: Intensidades acima do LV apresenta decl?nio na fun??o inibit?ria e desprazer. O desprazer foi relacionado com aumentos do PAD, da desoxihemoglobina no CPF e da atividade simp?tica. Os nossos resultados suportam que a intensidade do exerc?cio pode influenciar o controle inibit?rio e est? associado aos sentimentos afetivos. / Introduction: Low grip on most of the population in physical activity programs has been linked to emotional experiences of displeasure caused by the intensity of exercise. Theoretical studies suggest inhibitory control as a key element in regulating emotions of pleasure during exercise performed at different intensities. However, it is still unknown the relationship of inhibitory control with affective responses about the intensity of the exercise. Objective: To analyze the effect of the intensity of the maximum incremental exercise on the inhibitory control, affection, autonomic control and oxygenation of the PFC. Method: Thirty-seven young adults, sedentary, participated randomly in two experimental conditions (control and exercise). In the exercise condition, participants performed a maximal incremental test on a cycle ergometer with concurrent and continuous evaluation of oxygenation of the PFC, heart rate variability (HRV), inhibitory control (Stroop test), affection scales and associative/dissociative thinking (ADT). In the control condition, the volunteers performed the same evaluations of the exercise condition, but without pedaling a cycle ergometer. The benchmark of the experimental protocols for the intensity was determined by the ventilatory threshold (VT). ANOVA was used for repeated measures two away with Bonferroni adjustment, to compare the conditions (control and exercise) and times (eight intensities). Then the Pearson correlation was performed to verify the correlations of emotional feeling and inhibitory control with ADT, HRV and oxygenation of the PFC. Results: (I) high intensity exercise promoted decline in inhibitory control, unpleasantness feeling, increased sympathetic activity and cerebral oxygenation. (II) promoted the increase of the intensity correlation between the decline in inhibitory control (highest number of error) with increasing ADT (r=0.77) and cerebral PFC (DHB: r=0.87; HBT: r=0.75). (III) inhibitory control analyzed by the score efficience inverse, was worse in high and low intensity compared to their behavior at moderate intensity. Conclusion: Intensities above the VT provides decline in inhibitory function and displeasure. The displeasure was related to increases in ADT, the deoxyhemoglobin PFC and sympathetic activity. Our results support that the intensity of exercise can influence the inhibitory control and is associated with emotional feelings.
