The qualitative research used as methodological resources: 1) document analysis of the publications of São Bernardo do Campo’s Curriculum Guidelines for EJA and Professional Education – 2012, São Bernardo do Campo’s Professional Education Catalog – 2012; 2) bibliographical research based on Paulo Freire, in continuity with the studies in order to enable a more detailed and thorough analysis of the implantation of a professional education under a Freirean critical-liberating perspective; 3) field research in a professional education school in São Bernardo do Campo, in which we were able to examine the profiles of the interviewed through questionnaires and interviews, searching for evidences that could reveal, through the eyes of the teachers and principals, the facilitating and hindering factors for the implantation of a professional education under the critical-liberating perspective in São Bernardo do Campo / O presente trabalho foi desenvolvido buscando tratar sobre o processo de reorientação curricular da educação profissional de São Bernardo do Campo – SP, numa perspectiva crítica e libertadora freireana pelo olhar docente e gestor sobre a sua implantação, no período de 2010 a 2015, focalizando os fatores facilitadores e dificultadores do processo. A pesquisa de abordagem qualitativa utilizou enquanto recursos metodológicos: 1) análise documental das publicações das Diretrizes Curriculares da EJA e Educação Profissional de São Bernardo do Campo – 2012, do Catálogo da Educação Profissional de São Bernardo do Campo – 2012; 2) pesquisa bibliográfica fundamentada em Freire, em linha de continuidade aos estudos feitos com o objetivo de possibilitar uma análise mais apurada e cuidadosa da implantação de uma educação profissional na perspectiva crítica e libertadora freireana; 3) pesquisa de campo em uma escola de educação profissional em São Bernardo do Campo, em que pudemos levantar o perfil dos/as entrevistados/as através de questionários e a realização de entrevistas buscando a partir do olhar docente e gestor evidenciar quais os fatores facilitadores e dificultadores para a implantação de uma educação profissional na perspectiva crítica e libertadora em São Bernardo do Campo

In this dissertation the effects of variations in stimulus properties and CTOA, in auditory attention tasks were explored using recently developed approaches to EEG analysis including LIMO. The last experiment was structured using information theory, designing an effective experiment. Four studies were carried out using a number parity decision task, that employed different combinations of cueing Tone (T), Novel (N) and the Goal (G) stimuli. In the first EEG study, contrary to previous findings (Polich 2002, 2007) in control participants, no correlation between the time of a novel condition to the next novel condition and P300 amplitude was found. Therefore single trial across-subject averaging of participants’ data revealed significant correlations (r > .3) of stimulus properties (such as probability, frequency, amplitude and duration) on P300, and even r > .5 was found when N was an environmental sound in schizophrenic patients. In the second EEG study, simultaneously with fMRI recordings, the participants that showed significant behavioural distraction evoked brain activations and differences in both hemispheres (similar to Corbetta, 2002, 2008) while the participants, as a whole, produced significant activations mainly in left cortical and subcortical regions. A context analysis was run in distracted participants contrasting the trials immediately prior to the G trials, resulting in different prefrontal activations, which was consistent with studies of prefrontal control of visual attention (Koechlin 2003, 2007). In the third EEG study, the distractor noise type was manipulated (white vs environmental sounds) as well as presence or absence of scanner background noise in a blocked design. Results showed consistent P300, MMN and RON due to environmental noise. In addition, using time constants found in MEG results (Lu, Williamson & Kaufman, 1992) and adding the CTOA to the analysis, an information theory framework was calculated. After the simulation of the information of the experiment, a saddle indentation in the curve of the information measure based on the states of the incoming signal at around 300 ms CTOA was found. This saddle indentation was evident in more than 60 novel trials. In the fourth study, the CTOA and stimulus properties were manipulated in a parametric experiment. Based on the three studies, reducing complexity if the task (first study), using more than 60 stimuli in the novel conditions (third study). The CTOA randomly varying between 250 ms or 500 ms. Thirty-eight ANCOVA with 2 categorical and 1 continuous regressors were conducted and determined which time and channels elicited reliably signatures (p <.05) in the whole participants at short CTOA. Results revealed differences for the waveforms of current condition by depending on which condition appeared previously as well in terms of frequency and duration in scalp frontal electrodes (such as the second study). These results were interpreted as a consequence of switching between modes of attention and alerting states which resulted in the activation of frontal areas. Moreover, contextual analyses showed that systematic manipulation of stimulus properties allowed the visualization of the relationships between CTOA, executive function and orienting of attention.
