A influência do feedback verbal na cooperação em crianças

Human cooperation is a hallmark of this species due to its wide extension to genetically unrelated individuals and complex division of labor. It is considered an evolutionary puzzle, because the theory of evolution by natural selection predicts that self-interested individuals tend to be selected. Different theories have been proposed to explain the evolution of cooperation, which the most important are kin selection and reciprocal altruism. Considering the evolutionary continuity between species, humans and other primates have several common traits that help to promote cooperation between individuals of these species. Two features, however, seem to be particularly humans: inequality aversion and preferences in relation to others. Although human cooperation is not necessarily related to morality, cooperative traits are the basis for moral tendencies. The development of human morality is a combination of early prosocial tendencies, cooperative skills displayed at different ages, social learning and cultural transmission of norms. The social stimulus seems to be particularly important in promoting cooperative behavior in children and adults. In order to study the influence of social stimuli, as verbal feedback, on children cooperation, a study was conducted with children in a public goods game. 407 children from public schools in Natal / RN, divided into 21 groups, between six and nine years, participated in eight rounds of this game. After each round, seven groups received praise for larger donations, seven groups have been criticized by smaller donations, and the other seven received no comment. Children cooperated more when criticized, without significant differences between sexes, although young children have cooperated more negative than older children. The results are likely related to the anticipation and avoidance of punishment associated with the feedback (although this did not occur), and greater sensitivity to the authority in younger children. Nevertheless, the cooperation decreased in all groups until the last day of play. The results suggest an early sensitivity to moral punishment, whose role in the maintenance of social relations must have been important in the evolution of cooperation in humans

Efeitos do tratamento com lítio na memória aversiva, comportamentos relacionados à ansiedade e depressão e na expressão de BDNF em ratos

Lithium (Li) is the first choice to treat bipolar disorder, a psychiatric illness characterized by mood oscillations between mania and depression. However, studies have demonstrated that this drug might influence mnemonic process due to its neuroprotector, antiapoptotic and neurogenic effects. The use of Li in the treatment of cognitive deficits caused by brain injury or neurodegenerative disorders have been widely studied, and this drug shows to be effective in preventing or even alleviating the memory impairment. The effects of Li on anxiety and depression are controversial and the relationship of the effects of lithium on memory, anxiety and depression remain unknown. In this context, this study aims to: evaluate the effects of acute and chronic administration of lithium carbonate in aversive memory and anxiety, simultaneously, using the plus maze discriminative avoidance task (PMDAT); test the antidepressant effect of the drug through the forced swimming test (FS) and analyze brainderived neurotrophic factor (BDNF) expression in structures related to memory and emotion. To evaluation of the acute effects, male Wistar rats were submitted to i.p. administration of lithium carbonate (50, 100 or 200 mg/kg) one hour before the training session (PMDAT) or lithium carbonate (50 or 100 mg/kg) one hour before the test session (FS). To evaluation of the chronic effects, the doses administered were 50 or 100 mg/kg or vehicle once a day for 21 days before the beginning of behavioral tasks (PMDAT and FS). Afterwards, the animals were euthanized and their brains removed and submitted to immunohistochemistry procedure to quantify BDNF. The animals that received acute treatment with 100 and 200 mg/kg of Li did not discriminated between the enclosed arms (aversive and non-aversive) in the training session of PMDAT, showing that these animal did not learned the task. This lack of discrimination was also observed in the test session, showing that the animals did not recall the aversive task. We also observed an increased exploration of the open arms of these same groups, indicating an anxiolytic effect. The same groups showed a reduction of locomotor activity, however, this effect does not seem to be related with the anxiolytic effect of the drug. Chronic treatment with Li did not promote alterations on learning or memory processes. Nevertheless, we observed a reduction of open arms exploration by animals treated with 50 mg/kg when compared to the other groups, showing an anxiogenic effect caused by this dose. This effect it is not related to locomotor alterations since there were no alterations in these parameters. Both acute and chronic treatment were ineffective in the FS. Chronic treatment with lithium was not able to modify BDNF expression in hippocampus, amygdala and pre-frontal cortex. These results suggest that acute administration of lithium promote impairments on learning in an aversive task, blocking the occurrence of memory consolidation and retrieval. The reduction of anxiety following acute treatment may have prevented the learning of the aversive task, as it has been found that optimum levels of anxiety are necessary for the occurrence of learning with emotional context. With continued, treatment the animals recover the ability to learn and recall the task. Indeed, they do not show differences in relation to control group, and the lack of alterations on BDNF expression corroborates this result. Possibly, the regimen of treatment used was not able to promote cognitive improvement. Li showed acute anxiolytic effect, however chronic administration 4 promoted the opposite effect. More studies are necessary to clarify the potential beneficial effect of Li on aversive memory

Projeção retiniana, caracterização citoarquitetônica e neuroquímica da zona incerta do moco (Kerodon rupestris)

The Zona Incerta (ZI) is embryologically derived from the ventral thalamus, in continuity with the reticular nucleus of the thalamus. Studies usingneural tracers technics have allowed identify a complex connectional map including the ZI. Futhermore, cytochemical, molecular and functional data have shown abundant variability in the neurochemical contend in the ZI, as well as,the involvement of the ZI in the modulation of nociception, attention, alertness, control and maintenance of posture and control of visceral activity. This work aims to characterize the cytoarchitecture, neurochemical content of the ZI in the rock cavy (Kerodon rupestris), and a direct retinal-ZI pathway present in this species. The Nissl staining is effective for the delineation and characterization of ZI citoarchitecture. ZIc receives a contralateral retinal projection showing varicosities, suggesting a modulatory character of photic information. The ZI in the rock cavy, as in others rodents and primates, is characterized by a complex neurochemical signature. The ZI neurochemistry presents great diversity, especially in the medial portion of ZIr, where we have found immunoreactivity of all neuroactive substances investigated, and that NOS-IR, GFAP and CR helped the delimitation of middle ZI in ZId and ZIv. Nevertheless, just 5-HT-IR fibers are present in all subdivisions of the ZI. These data demonstrate the great wealth of the neurochemistry of rock cavy s ZI and a direct retinal modulation in the ZI, helping to explain it s broad functional repertory

Avaliação do programa de tutorização da EMATER-RN para servidores em estágio probatório

The present thesis evaluated the contributions and limitations of the tutorship program introduced in EMATER-RN, as a tactic of organizational socialization for civil servants in probationary stage. Tutorship was understood as an intensive and continuous relational process, in which a more experienced person in the organization the tutor offers psychosocial support, stimulates the development of the professional career and enables to the newcomer the tutee learning on job performance. The organizational socialization was considered in the perspective of the symbolic interactionism. The study was characterized as a program evaluation and as an action research. The practical interventions for the program implementation were conducted and, at the same time, the evaluations of process, results and reaction to the program were applied. Among the major contributions of the action research, it stood out: the diagnosis of reasons for the formation of the pair and of expectations of tutors and tutees, the improvement of the tutorship registration tools, the ascertainment of the success of the program in the socialization of the new civil servants, the confirmation of the importance of the compatibility among them and of the adequate performance of tutorship functions for achieving its benefits. Based in constraints of the program, one may quote as essential recommendations: the formation of a technical team supporting the program, the clear establishment of deadlines for each procedure and the reinforcement to its compliance, the investigation of the functions performed by the tutor, the sensitization of the managers to the resolution of problems that affect the program, the voluntary participation of the tutor and the continuous meetings of tutors and tutees. One settles for the relevance of the program and in favor of its continuation, provided that its improvement and systematic management are conducted.

Do útero à adoção: a experiência de mulheres férteis que adotaram uma criança

Even with all changes and ruptures related to the social roles that woman had performed, the literature had confirmed that the motherhood still configures it like one of the main roles that she hopes to play in some moment of her life. When the woman did not get pregnant or take ahead a pregnancy, some women find in adoption an alternative to play this role. This research aimed to understand the experience of being mother for adoption in the case of fertile women, but whose partner is infertile. Supported by existential-phenomenological theory, used it the narrative, how methodological instrument. Participated five women, whose adoption process followed the legal ways in the Youngness and Infancy Judgeship of Natal/RN. The results showed that in the selfish training, the woman to see herself how whose role principal is to generate children, although, she think that is natural her participation in others activities go out home too. In male infertile case is a tendency that the woman strikes the infertile status too. The adoption is an alternative to fulfill her desire of being a mother and, meanwhile, please her husband and guarantee the continuity of her love relationship. Through motherly care, the woman discover herself as a mother, what brings a new meaning for her live, independent of to generate a child. Though, exit frustration, sometimes, in association with suffering, on account of the pregnancy and childbirth absence. The end of the research suggests reflections that to become fulfilled herself as mother, the woman does not need, necessarily, to generate a child, being the maternity one of the uncountable possibilities that are shown, and that she can choose, or not, accomplish it

No pulsar da clínica: a repetição e as produções corporais de uma criança

This study investigates the Repetition of movements shown in a stereotypical case of a child three years old. In line with the psychoanalysis model of search, this work presents fragments of the clinic process, the locus for the observation of repetitive, ritualized and choreographically movements of this child who used not to speak. The contrast between their movements and the issuance of a word verbalized at the end of the treatment caused the following question: repetition in this child production would be a reproduction of the same or would be directing for the difference? In the psychiatric speech, the stereotypes are listed as diagnostic criteria for certain mental disorders. In the psychoanalysis studies a question about the psych nature of ritualistic gestures apparently without purpose or direction is included. Thus, the route followed was the reading of the theoretical concept of repetition in the psychoanalytic works of S. Freud and J. Lacan. With Freud, the repetition is linked to the transfer and resistance. In that context, when it appears in act, in the place of the talk, it constitutes a particular way of remembering. But the existence of a force in the psychic apparatus that acts independent and involuntarily of the Principle of pleasure (the repetition compulsion) subsidizes the discovery of Freudian pulsion of death that is the tendency to return to itself. In the Lacan reading, the function of Repetition is magnified, as it fulfils two functions: the automaton - reminders of repetitive signs, and that the service of tiqué - the meeting of the subject with his lack constituent. In this sense, repetition is not simply a reproduction, but the search for new, the difference, caused by the lack of continuity that pushes the circuit. Finally, the clinic process and the theoretical readings made the comprehension of the child repetitive and choreographically movements and the pronouncement of a "good-bye", full of meaning. This repetitive scenario which is full of questions, by this very nature, insists in remains inconclusive

O aborto provocado como uma possibilidade na existência da mulher: reflexões fenomenológico-existenciais

Abortion is a very controversial and stigmatized subject, target of many criticism and discussions, mainly regarding to the legal, bioethical and religious aspects involved. In Brazil, abortion is considered a serious public health problem, being the major cause of maternal death due to its criminalization. The woman who causes an abortion is not up looked by society, since motherhood, culturally and historically, was imposed as a destination. Our main goal is to understand, from the existential-phenomenological perspective, the unique experience of the woman who induced the abortion This study is an offshoot of a larger study from USP in partnership with UFRN. Our participants were women who checked in on a maternity hospital in Natal with a miscarriage diagnosis and, among them, those who reported having induced abortion. Altogether, five women were interviewed. The used method was a phenomenological hermeneutics. The research revealed that the experience of abortion is a possibility that permeates women s life, being understood as a choice. This choice pervaded by much suffering, once it goes against everything that women are culturally taught and meant to be. The feeling more surfacing in this experiment, confirming the literature review, was blame. Abortion was also shown as an experience of helplessness and loneliness, due to lack of support from family and the partner. It was also revealed that abortion was made, mainly, by the desire of going along with future projects, including the prosecute of motherhood in the therms of what they consider ideal to a son s arrival, meaning, a family formation grounded on a stable relationship. Regarding the care provided by health professionals to these women, there is the need of restructuring the operating logic of SUS, so that women have the right to health in a integrate manner. This experience also made women reconsider the meanings they had towards abortion, and their life projects

Adaptação e validação da escala de dependência de exercício físico em versão tradicional e informatizada

While providing physical and psychological benefits, excessive exercise could be or cause a compulsive behavior, making the individual dependent on it. In a parallel discussion, computerized psychological instruments, for a hand, reflects the development of information technology and your applicability to other areas, but also shows little advance for Psychological Assessment. In this perspective, this study aims to adapt the Exercise Dependence Scale (EDS-R) in two formats (paper-and-pencil and computerized) and evaluate evidence of factorial and convergent validity, and reliability of each version and compare them with each other. It is also proposed to observe the relationship of some bio-demographic (Sex, age, frequency, duration and intensity of practice exercise) and the exercise dependence (DEF). For this purpose, 709 regular physical activity practitioners, selected by procedures non-probabilistic sampling, responded a adapted version of EDS-R, Muscle Appearance Satisfaction Scale (MASS), Body Modification Scale (BMS) and a demographic questionnaire, analyzed through Exploratory Factor Analysis, Cronbach's Alpha and not parametric tests. Both the traditional version and the computer showed a seven factors structure, explaining 57 and 62% of the variance, respectively, and Cronbach's alphas of 0.83 and 0.89. Factors were: (1) intentionality, (2) continuity, (3) tolerance, (4) reduction of other activities, (5) lack of control, (6) abstinence and (7) time spent on exercise. Relationships were observed between the Exercise Dependence and the variables: age, diets, consumption of food supplements and medicines for weight change, desire to do plastic surgery and body satisfaction. We observed also a positive correlation between the DEF and the frequency, duration and intensity of exercise, and the factor "Dependence on exercising" from MASS, indicating convergent validity of the EDS-R. Finally, comparisons between the two formats were equivalent, with few changes: computerized version achieved higher DEF scores. Based on these results, it can be concluded that the EDS-R has factorial and convergent validity, reliability, to measure exerceise dependence on traditional e computerized formats. DEF is related to actions used to body modification and behaviors toward exercise. Finally, it was found equivalence between the formats, especially in psychometric parameters, thus suggesting feasibility of a computerized assessment. However, it was observed that the computerized data has sample recruiting strategies more limited

De vilarejo a cidade: identidade de lugar de moradores nativos de Tibau do Sul-RN

This study aimed to analyze some indicators of the restructuring process of place identity of natives resident in Tibau do Sul, a coastal town in the state of Rio Grande do Norte state, in relation to changes occurring in this locale in the last few decades. The concept of place identity a complex psychological structure in constant process of restructuring stresses the focus of this analysis on the aspects referring to the relationships of people with their physical and social environment throughout the transition process from the former village of fishermen and peasant farmers to the current growing town. Interviews with insider informants on local history were carried out as a preliminary step to getting in touch with the native participants. In total, 29 native local residents were interviewed, according to a wide range of personal and professional roles, focusing on their cognitions in regard to their past and present relationships with this context, as well as those related to expectancy for the future. The analysis focused both on the elements of distinctiveness, continuity, self-esteem and self-efficacy, and on how each of them have been valued (positive or negative). The participants evaluations of themselves and of the locale, as well as their distinctions in relation to others (people and places) were, in general, very positive. Many elements of group and place continuity, and the possibility of the satisfaction of their needs were highlighted positively, especially comparing to similar situations in the past. The development of the town, related to tourism as well as to other former economic activities, seemed to contribute to the restructuring process of place identity in a way of achieving desirable states for its structure. The broadening of the analysis to consider a wider spatial and temporal context, however, shows that such positive evaluation can be said to hinder some coping strategies of local residents faced with unsustainable economic activities, oftentimes handled to favor a minority of the population

Experiências maternas de perda de um filho com câncer infantil: uma compreensão fenomenológico-existencial

Death due to childhood cancer reflects an early outcome of life, which can cause a strong repercussion in the mother s existence - figure to whom the greatest part of responsibilities during the child s illness is commonly allocated. The aim of this study is to understand the experience of mothers who have lost a kid as a consequence of childhood cancer, approaching the personal senses of this fact. Following a qualitative research design, with an exploratory and comprehensive approach, the study used the narrative method, which was obtained from a semi-structured interview, as the data generation procedure. The research counted on the participation of three adult mothers who had lost their kids because of childhood cancer, after - at least - a six-month period of oncologic treatment. The proposal of analysis follows the parameters of the phenomenological method and the data are based on Martin Heidegger s existential analytic. The results were structured into three thematic axes: previous History, child illness and its repercussions; The network of support and care; Loss and after loss: facing and signifying. It was possible to comprehend that the emergence of cancer in childhood promotes, since the diagnosis, a disruption of everyday meanings, accentuating the fragile condition of human life. In this specific circumstance of childhood illness, all the participants restricted their possibilities of being-in-the-world, dedicating exclusively to the practice of maternity. Concerning their relationship with their children in treatment, the narratives unveiled, in a convergent manner, the existence of care in a substitutive mode. In the network of support - primarily constituted by family, the health team and the support institutions - the relations were marked by proximity and detachment movements. With the child s death, mothers began to live a way of being-with the absent child , ensuring the continuity of the relationship with the dead infant. From the results exposed above, we can understand the motherly mourn as a singular experience in constant resignification, in which the subjective time overlaps the cronological time. The increment of anguish, resulting from the mother s confrontation to the question of finitude, mobilizes a process of change in their way of being-in-the-world, promoting an openness to new possibilities in their lives. Singular attention to the mother, during the process of illness and child loss, turns out to be fundamental

Adaptação transcultural para o Português/Brasil do instrumento vulnerability to abuse screening scale (VASS)

Esse trabalho objetivou promover a adaptação transcultural para o Brasil da VASS. Os passos para adaptação transcultural seguirão a proposta de operacionalização alicerçado na apreciação de diferentes tipos de equivalência: a conceitual e de itens, a semântica e a de mensuração. Para alcançar as duas primeiras etapas utilizou-se as técnicas de tradução e retrotradução associada ao procedimento intitulado Painel de Especialistas. Para o pré-teste e verificação de equivalência de mensuração, aplicou-se o questionário com uma população de 30 e 66 idosos, respectivamente. Para as análises dos resultados foi utilizada a estatística descritiva e inferencial, em especial o KR-20, teste T de student, correlação de Pearson e ANOVA univariada, bem como o método kappa de Fleiss para verificação do índice de confiabilidade. Verificou-se que o conceito utilizado para construção do instrumento, bem como seus itens se mostram adequados à investigação do fenômeno. Evidenciou-se boa equivalência semântica entre os itens das retrotraduções e do instrumento original, especialmente quanto aos resultados de T1 R1. Os juízes optaram pelo uso de 11 itens de T1 à versão-síntese. A equivalência operacional mostrou-se satisfatória. Em geral, os resultados apresentados mostraram-se aceitáveis. Quanto à etapa da equivalência de mensuração, verificou-se que a idade dos participantes variou entre 60 a 84 anos, prevalecendo respondentes idosas (n = 38), representando 57,6% da amostra estudada. O valor do KR-20 para o escore geral do instrumento foi de 0,688 (IC95%: 0,670). Os valores encontrados para as quatro dimensões propostas pelos autores do estudo inicial do instrumento foram 0,528, 0,289, 0,552 e 0,303, respectivamente. Apenas os valores de consistência interna das subescalas Vulnerabilidade e Coerção mostraram-se aproximados aos encontrados no estudo original, a saber, 0,550 e 0,390, respectivamente. Verificou-se que com a retirada dos itens nº 04, nº 06 e nº 10, houve aumento do índice de consistência interna da escala total. Já quanto aos valores da consistência interna das subescalas, percebeu-se que apenas com a retirada dos itens nº 09, referente à escala que dimensiona o Desânimo, e nº 12, item da subescala Coerção, é que houve acréscimo nesses valores. Destaca-se que esses são resultados preliminares, uma vez que após a verificação da adequabilidade e de padrões psicométricos iniciais acerca do uso do instrumento para a população idosa, ainda há de se dar continuidade à etapa concernente à verificação de propriedades psicométricas robustas do instrumento, que indiquem, por exemplo, evidências de fidedignidade em situação de teste-reteste, validade de constructo e de critério, se possível e aplicável. A principal limitação do estudo é a falta de um instrumento padrão-ouro para testar a fidedignidade, sensibilidade e especificidade do instrumento em questão. Apesar desta limitação, a adaptação transcultural e a verificação de propriedades psicométricas preliminares do instrumento de uma medida de autorrelato que afere indicativo de violência doméstica contra o idoso tem sua relevância e foi satisfatória

Superando a aridez do semi-árido: encontros entre saúde mental e saúde da família na formação de médicos no alto sertão paraibano

A atenção primária à saúde é um importante cenário para o cuidado em saúde mental por suas características e pelo trabalho no território contribuir para a superação do modelo manicomial de atenção. Esta pesquisa partiu do questionamento sobre como acontece a atenção em saúde mental na atenção básica nas unidades em que se desenvolve a Residência de Medicina de Família e Comunidade em um município do sertão paraibano. Objetivou investigar as demandas de saúde mental e práticas de cuidado no contexto de ESF e da RMFC do município de Cajazeiras a partir do discurso dos profissionais ali inseridos e discutir estratégias de qualificação do cuidado em saúde mental nessa realidade. Utilizou-se abordagem qualitativa em que foram realizados grupos focais envolvendo profissionais de duas equipes da ESF e uma equipe de NASF. Os dados produzidos nos grupos foram analisados a partir do referencial da análise do discurso de inspiração foucaultiana. Como resultados evidenciou-se que os profissionais percebem a demanda em saúde mental na atenção básica principalmente na forma de sofrimento psíquico inespecífico e transtornos mentais graves. A atenção a essas pessoas não consegue superar a medicalização que é identificada por esses profissionais. A prática asilar persiste como alternativa para os casos de transtornos mentais graves, sendo limitada a incorporação do paradigma da desinstitucionalização como referencial para a prática profissional. Além disso, a relação com a rede de saúde encontra vários limites destacando-se a dificuldade de produção de continuidade e integralidade do cuidado. A partir disto, analisa-se a formação médica e sua capacidade de garantir o cuidado integral na atenção às demandas de saúde mental. No campo da pesquisa, dois modelos de formação se encontram. Os residentes participantes ou graduaram-se em Cuba ou em escola médica brasileira orientada pelas Diretrizes Curriculares Nacionais. Percebe-se então que a graduação, ao incorporar questões relativas à integralidade do cuidado, não é suficiente para gerar bons profissionais para o SUS. Considera-se necessário somar às mudanças na graduação a perspectiva da Educação Permanente em Saúde no mundo do trabalho, o envolvimento dos profissionais com a transformação das práticas de atenção à saúde e a construção da perspectiva da integralidade e da atenção psicossocial por dentro da Residência de Medicina de Família e Comunidade como importantes estratégias para a formação de médicos generalistas aptos para a atenção às demandas de saúde mental
