Self-regulatory behaviours and flow dispositions in musical practice: a survey with advanced performers

Flow experience, a holistic sensation of total involvement in an activity, seems to have positive influences on musical performance activities. Although its main requirements (balance between challenges and skills, clear goals and unequivocal feedback) are inherent elements of musical practice, there is a lack of research about flow occurrences in the context of musical practice and on how specific practice behaviours affect the experience of flow and its particular dimensions. The aims of this thesis were to investigate advanced performersʼ dispositions to flow in musical practice, and to investigate whether the frequency of these experiences of holistic engagement with practice are associated with self-regulatory practice behaviours. 168 advanced classicallytrained performers (male = 50.0%; female = 50.0%), ranging in age from 18 to 74 years (m = 34.41, SD = 12.39), answered a survey that included two measures: the Dispositional Short Flow Scale, assessing performersʼ flow dispositions, and the Self-Regulated Practice Behaviours Questionnaire, developed specifically for the present research. The overall results of the survey suggested that advanced musicians have high dispositions to flow in musical practice, but not associated with the participantsʼ demographic characteristics. Three of the individual flow indicators were less experienced, suggesting that the most intense flow experiences are rare in musical practice. However, the results point to the existence of another relevant experience, named optimal practice experience. Practice engagement levels were positively associated with knowledge of oneʼs own personal resources and a capacity for practice organization, but not with inclusion/use of external resources. A capacity for setting optimal practice goals was related to self-regulation and to immersion aspects of flow. Current findings offer new clues about the assessment of flow dispositions in performers, helping to clarify how daily practice can heighten positive affective responses in musicians who are vulnerable to the requirements and difficulties of deliberate practice, as well as to other negative practice outcomes. The current research questions issues pertaining to the optimization and sustaining of flow in daily practice, suggesting future directions in the study of the affective subjective functioning of engagement with deliberate practice.

Integrated approach to teaching English in primary and preschool

O presente trabalho de investigação apresenta um estudo que procurou observar comportamentos de literacia emergente numa língua estrangeira (Inglês) em contexto da educação pré-escolar. Procedeu-se à conceção e implementação de uma abordagem integrada ao ensino da língua inglesa, através numa abordagem metodológica inspirada no paradigma investigação-ação, percecionada como oportunidade de inovação pedagógica e de formação de professores. O estudo foi desenvolvido em simultâneo no 1ºCEB, tendo como principal objetivo comparar os comportamentos e atitudes dos alunos de outra faixa etária relativamente aos comportamentos de literacia em língua estrangeira. Os dados foram recolhidos através da observação, gravação de aulas, posteriormente transcritas, diários do investigador, questionários, portfolios dos alunos e entrevistas semi-estruturadas a especialistas na área da pedagogia de línguas estrangeiras, analisados através da aplicação de técnicas de análise de conteúdo como procedimento de análise do corpus. Os resultados demonstram a relevância de abordagens integradas de cariz lúdico na promoção de comportamentos de leitura e escrita emergente, estimulando assim motivação intrínseca nas crianças pela aprendizagem da língua e cultura-alvo. Por conseguinte, os comportamentos observados de literacia emergente em língua estrangeira permitem estabelecer uma analogia com as crianças bilingues, na medida em que ao aprenderem uma outra língua desenvolvem em sincronia a sua flexibilidade mental e estratégias de auto-regulação em diversas áreas de conhecimento. Os resultados permitem ainda concluir que estratégias promotoras de motivação intrínseca como o lúdico e o storytelling são vitais na sensibilização à diversidade linguística e cultural, por oposição aos resultados evidenciados pela estratégia nacional para o ensino de línguas estrangeiras no 1.ºCEB. As principais implicações deste estudo sugerem a possibilidade de generalização da língua estrangeira na educação pré-escolar, sendo esta etapa compreendida como um período privilegiado na prevenção de insucesso na leitura e escrita na aprendizagem de uma língua estrangeira. Deste modo, a educação pré-escolar pode ser considerada como um tempo fundador do futuro linguístico das crianças, numa perspetiva de educação linguística ao longo da vida.

Altered regulatory response of Rab7a and Rab9 in MM1 and VV2 subtype of Creutzfeldt-Jakob disease

The present study was undertaken to identify proteins interacting with PrPC that could provide new insights into its physiological functions and pathological role. We performed a target search for lysosomal network protein, Rab7a and Rab9, in frontal cortex and cerebellum of human brain from patients with sCJD-MM1 and sCJD-VV2. The intracellular level of Rab7a was increased significantly, when compared with healthy age-matched control. Interactions of PrPC and Rab7a/Rab9 were further investigated by using confocal laser scanning microscopy. Immunofluorescence results suggested potential interactions of Rab7a and PrPC. siRNA against the Rab7a gene was used to knockdown the expression of Rab7a protein in primary cell culture of cortical neurons from wild type mice. This depleted Rab7a resulted an impairment of PrPC trafficking leading to an accumulation of PrPC in the endocytosis pathway. Furthermore, interactions of Tau and Rab7a were investigated by using western blot analysis and confocal laser scanning microscopy. Cell cultures of cortex of wildtype mice were treated with siRNA-Tau, siRNA-Rab7 and control siRNA followed by immunofluorescence. The results of immunofluorescence suggested potential interaction of Tau and Rab7a. Cells lines treated with siRNA-Tau, the intracellular levels of Rab7a and Rab9 significantly increases and their localization is also modified. When we transfected this cells lines with siRNA-rab7a the accumulation of Tau decreases in cytosolic region and their localization was also modified when compared with control cells. In conclusion, this study may help to understand and characterize the subtype specific disease progression in CJD cases. Furthermore, it could be a step ahead to development of new treatment strategies for diseases subtype specific manner.
