Metacognitive experience and transfer of logical reasoning

The experiments examine the influence of metacognitive experience on the transfer of logical processes in a problem solving setting. Subjects were presented with two versions of Wason's (1966) selection task. Although they were able to perform successfully on the concrete tasks (following a minimal explanation of the correct solution on an initial trial), the majority were not able to transfer a successful method to the abstract tasks. Verbalization during, or following, the concrete tasks produced substantial transfer effects however. It is suggested that verbalization may lead to an increased awareness of past behaviour, particularly of those aspects necessary for successful solution.

A recepção da criança com deficiência intelectual ao texto literário na educação infantil

The focus of this thesis is children's reception to literary texts starting from literary livelihood in an inclusive literary context, looking for the possible evidences that are present in the construction as reader/hearing of literature. Based on a study case, we search the ways of participation of a child (girl) with intellectual deficiency in situations of offering and reception of literary texts, looking for the understanding and explication of some aspects of her processing and the building up of an initial reader. The data were taken starting from observations in moments of reading and story-telling in the period from November to December/2008 and May to June/2009 in a public school of children education, in Natal- Brazil, in which there was a registered student showing intellectual deficiency associated to Down syndrome. As research tools we used: field diary, interview scripts and video recordings. The analyses were based on research from Amarilha (2001, 2006a, 2006b), Bettelheim (2007), Coelho (2008), Iser (1996), Jauss (1979, 1994), Luria (1990a, 1990b), Vygotsky (1991, 1993), Wallon (2007, 2008) amongst others. The research showed that although expressing little verbalization and limited levels of attention, body attitudes, movements and talks of the child under investigation, denounced engagement and rendition to the sonority of the texts shared. These data gives us traces that, under a mediating action, the child with intellectual limitation can turn into a reader/hearing subject of literature, developing a sensitive and a selective attitude towards the literary text. Amongst other aspects, we identified that (1) a conception of deficiency present through the school that recognizes his/her potential of developing and learning (2) the situation of sharing, that favours a relation with the texts through the other, and (3) the relevance of orality providing the semantic paths that help the child in the building up of meaning, presenting themselves as fundamental to her/his viewing of the literary text, and, therefore, the formation of the reader. Thus, recognizing her/his capacity and possibilities, we think it is important to guarantee to the child with intellectual deficiency, a space towards interaction with the fictional text in which the child can learn and live its ludic and interactive character, to enjoy its hearing abilities, benefiting, then, from the aesthetic experience lived, mainly, in collective situations mediated through the more experient reader and shared with her/his different pairs. The research shows yet that, looking after conditions that guarantee a comfortable environment to the story hearings in the classrooms that focus on children education, being aware of a selection and the prosody of stories, the didactic contract, the attention to individual reactions, enlarge the possibility of any child deficient or not to enjoy her/himself as reader/ hearing subject of literature, engaged in its richness and magic

Análise das funções de verbalizações de terapeuta e cliente sobre sentimentos, emoções e estados motivacionais na terapia analítico-comportamental

Estudos recentes têm sido realizados por analistas do comportamento visando um maior conhecimento sobre as funções que relatos autodescritivos de sentimentos, emoções e estados motivacionais (SEM) podem exercer no processo terapêutico, o que permitiria o desenvolvimento de um modelo de intervenção analítico-comportamental frente a tais relatos. O presente estudo investigou, na evolução de um caso clínico, as possíveis relações entre as verbalizações do cliente que faziam referências a SEM, as intervenções do terapeuta frente a esses relatos, e a evolução dos problemas ou queixas do cliente. Os participantes da pesquisa foram uma terapeuta analítico-comportamental experiente que atendeu uma cliente adulta, casada, sem histórico psiquiátrico. Foram gravadas, transcritas e analisadas 36 sessões de atendimento, correspondentes a um período de um ano de atendimento terapêutico. A análise das verbalizações ocorridas nas sessões foi feita com base em quatro tipos de categoria, sendo duas referentes à terapeuta: categorias relativas às funções básicas das verbalizações de terapeuta (FBVT) e categorias de análise; e duas referentes à cliente: categorias de análise e indicadores de queixa ou mudança. Essas categorias também foram comparadas em relação à suaocorrência dentro e fora de episódios emocionais (EE), definidos como seqüências de diálogos entre terapeuta e cliente nas quais houve pelo menos uma referência a um SEM da cliente. A análise dos resultados mostrou que as principais queixas da cliente foram em relação ao marido, a eventos corporais, ao estado de humor, aos pais ou familiares, aos colegas de trabalho e à falta de assertividade. Os SEM mais referidos nos relatos da cliente e da terapeuta foram aqueles relacionados a estados motivacionais, à tristeza e ao medo. Em relação à terapeuta, verificou-se que suas intervenções frente aos relatos com referências a SEM ocorreram principalmente sob a forma de investigações e confrontações, mas apenas uma pequena proporção dessas intervenções sugeria relações entre uma resposta da cliente e contingências ambientais, predominando dentre estas, as relações do tipo antecedente-resposta. Comparada com a terapeuta, a cliente estabeleceu um maior número de relações entre eventos ambientais e suas respostas, também predominantemente do tipo antecedente-resposta. No que se refere à evolução das queixas relatadas, pode-se afirmar que não houve evidência da ocorrência de mudanças consistentes no repertório da cliente nem na forma como a mesma se referia aos seus problemas. Comparando as categorias investigadas dentro e fora dos EE, verificou-se uma maior variação nas FBVT, nas categorias de análise da terapeuta e da cliente, e um maior número e variação das ocorrências de indicadores de queixa ou mudança dentro de tais episódios. Tais resultados confirmam que sentimentos, emoções e estados motivacionais são alvos de investigação e intervenção do terapeuta analíticocomportamental, mostrando-se consistentes com a literatura existente. As referências de terapeuta e cliente a SEM ou eventos relacionados fortalece a idéia de que os mesmos podem ser tratados em alguns momentos como respostas encobertas, em outras ocasiões, como estímulos privados, e muito freqüentemente como relações das quais participam esses eventos, algumas vezes conjuntos de relações interconectadas. Verificou-se ainda que a eventual inobservabilidade de termos das relações comportamentais que definem os SEM não conduziu a uma abordagem diferenciada por parte do terapeuta. Por outro lado, as referências a SEM por terapeuta e cliente pareceu favorecer a ocorrência de verbalizações que estabelecem relações entre o comportamento da cliente e eventos ambientais.

A educação jurídica positivista e as diretrizes do ensino jurídico: currículo e prática pedagógica no curso de direito da UFPA no horizonte das competências e habilidades

O presente trabalho discute a educação jurídica contemporânea tomando por base a influência do legado teórico e metodológico do positivismo jurídico sobre a organização do currículo dos cursos de direito do Brasil. Analisa especificamente o projeto político-pedagógico do curso de direito da Ufpa e o currículo dele decorrente, que está adstrito aos pressupostos teóricos do dogmatismo, nitidamente observado pela escolha de disciplinas que seguem o roteiro do direito legislado e pela pedagogia unilateral desenvolvida em classe, baseada predominantemente em aulas expositivas. A pesquisa privilegia a análise crítica das Diretrizes Curriculares Nacionais do Ensino Jurídico, que optou por competências e habilidades críticas, reflexivas e humanistas, no contraponto com o projeto político-pedagógico do curso da Ufpa, organizado no sentido mais tradicional como grade curricular, onde persistem as práticas pedagógicas dogmáticas, o ensino como transmissão de conhecimento, como verbalização de conteúdos formais que prioriza regras e procedimentos e que sonega as aprendizagens para a emancipação.

Relações entre o perfil comunicativo de crianças com síndrome de Asperger e estratégias de professores

The aim of this research was to investigate the communicative profile of children with Asperger syndrome and the communicative resources used by teachers during interaction with these students in regular education. Five children, from 5 to 8-year-old-male, with Asperger syndrome and their teachers participated in the study. Their school grade ranged from pre-school to second grade elementary school. The characterization of the sample was obtained from an Informative Form and the Scale for the Assessment of Autistic Behavior. The communicative profile of the children and the resources used by their teachers were analyzed from the recorded footage. The results have showed that the teachers prompted the communication more often than the students with Asperger Syndrome and that the resources used by them were: 1 - concrete object, 2 - gesture, 3 - writing; 4-verbalization.

Educação de jovens e adultos: a construção das operações aritméticas em matemática

Working with adult students who attend literacy rooms has been set a challenge for educators, especially with regard to issues of learning mathematics. This work of course completion intention was to investigate the process of construction of arithmetic operations in mathematics from the perspective of the students themselves. Thus specific objectives were to investigate how these students face simple operations that can do this automatically on a daily basis, but not always systematized in the classroom; how these students think and communicate their ideas to the mental operation of the paper record. To this end we chose a qualitative research approach with characteristics of case study, conducted in a room of Youth and Adult participants with three ladies. The data collection occurred through the application of a semi-structured, audio recorded and later transcribed, which issues the verbalization sought and a description of how to give students the learning process of some mathematical content. The results showed that students bring with them skills, cultures and values to the classroom and that these are the basis for understanding the content. The teacher of adult education must take into consideration everything that the student brings to the classroom, their experiences, their history and culture, thus questioning the real world, so they can understand math in a way closer to their daily lives

Brain sources of EEG gamma frequency during volitionally meditation-induced, altered states of consciousness, and experience of the self.

Multichannel EEG of an advanced meditator was recorded during four different, repeated meditations. Locations of intracerebral source gravity centers as well as Low Resolution Electromagnetic Tomography (LORETA) functional images of the EEG 'gamma' (35-44 Hz) frequency band activity differed significantly between meditations. Thus, during volitionally self-initiated, altered states of consciousness that were associated with different subjective meditation states, different brain neuronal populations were active. The brain areas predominantly involved during the self-induced meditation states aiming at visualization (right posterior) and verbalization (left central) agreed with known brain functional neuroanatomy. The brain areas involved in the self-induced, meditational dissolution and reconstitution of the experience of the self (right fronto-temporal) are discussed in the context of neural substrates implicated in normal self-representation and reality testing, as well as in depersonalization disorders and detachment from self after brain lesions.

Colors in Mind: A Novel Paradigm to Investigate Pure Color Imagery

Mental color imagery abilities are commonly measured using paradigms that involve naming, judging, or comparing the colors of visual mental images of well-known objects (e.g., “Is a sunflower darker yellow than a lemon”?). Although this approach is widely used in patient studies, differences in the ability to perform such color comparisons might simply reflect participants’ general knowledge of object colors rather than their ability to generate accurate visual mental images of the colors of the objects. The aim of the present study was to design a new color imagery paradigm. Participants were asked to visualize a color for 3 s and then to determine a visually presented color by pressing 1 of 6 keys. The authors reasoned that participants would react faster when the imagined and perceived colors were congruent than when they were incongruent. In Experiment 1, participants were slower in incongruent than congruent trials but only when they were instructed to visualize the colors. The results in Experiment 2 demonstrate that the congruency effect reported in Experiment 1 cannot be attributed to verbalization of the color that had to be visualized. Finally, in Experiment 3, the congruency effect evoked by mental imagery correlated with performance in a perceptual version of the task. The authors discuss these findings with respect to the mechanisms that underlie mental imagery and patients suffering from color imagery deficits.

The functional significance of EEG microstates-Associations with modalities of thinking

The momentary, global functional state of the brain is reflected by its electric field configuration. Cluster analytical approaches consistently extracted four head-surface brain electric field configurations that optimally explain the variance of their changes across time in spontaneous EEG recordings. These four configurations are referred to as EEG microstate classes A, B, C, and D and have been associated with verbal/phonological, visual, attention reorientation, and subjective interoceptive-autonomic processing, respectively. The present study tested these associations via an intra-individual and inter-individual analysis approach. The intra-individual approach tested the effect of task-induced increased modality-specific processing on EEG microstate parameters. The inter-individual approach tested the effect of personal modality-specific parameters on EEG microstate parameters. We obtained multichannel EEG from 61 healthy, right-handed, male students during four eyes-closed conditions: object-visualization, spatial-visualization, verbalization (6 runs each), and resting (7 runs). After each run, we assessed participants' degrees of object-visual, spatial-visual, and verbal thinking using subjective reports. Before and after the recording, we assessed modality-specific cognitive abilities and styles using nine cognitive tests and two questionnaires. The EEG of all participants, conditions, and runs was clustered into four classes of EEG microstates (A, B, C, and D). RMANOVAs, ANOVAs and post-hoc paired t-tests compared microstate parameters between conditions. TANOVAs compared microstate class topographies between conditions. Differences were localized using eLORETA. Pearson correlations assessed interrelationships between personal modality-specific parameters and EEG microstate parameters during no-task resting. As hypothesized, verbal as opposed to visual conditions consistently affected the duration, occurrence, and coverage of microstate classes A and B. Contrary to associations suggested by previous reports, parameters were increased for class A during visualization, and class B during verbalization. In line with previous reports, microstate D parameters were increased during no-task resting compared to the three internal, goal-directed tasks. Topographic differences between conditions concerned particular sub-regions of components of the metabolic default mode network. Modality-specific personal parameters did not consistently correlate with microstate parameters except verbal cognitive style which correlated negatively with microstate class A duration and positively with class C occurrence. This is the first study that aimed to induce EEG microstate class parameter changes based on their hypothesized functional significance. Beyond, the associations of microstate classes A and B with visual and verbal processing, respectively and microstate class D with interoceptive-autonomic processing, our results suggest that a finely-tuned interplay between all four EEG microstate classes is necessary for the continuous formation of visual and verbal thoughts, as well as interoceptive-autonomic processing. Our results point to the possibility that the EEG microstate classes may represent the head-surface measured activity of intra-cortical sources primarily exhibiting inhibitory functions. However, additional studies are needed to verify and elaborate on this hypothesis.

Knowledgeable Feedback via a Cast of Virtual Characters with Different Competences

DynaLearn (http://www.DynaLearn.eu) develops a cognitive artefact that engages learners in an active learning by modelling process to develop conceptual system knowledge. Learners create external representations using diagrams. The diagrams capture conceptual knowledge using the Garp3 Qualitative Reasoning (QR) formalism [2]. The expressions can be simulated, confronting learners with the logical consequences thereof. To further aid learners, DynaLearn employs a sequence of knowledge representations (Learning Spaces, LS), with increasing complexity in terms of the modelling ingredients a learner can use [1]. An online repository contains QR models created by experts/teachers and learners. The server runs semantic services [4] to generate feedback at the request of learners via the workbench. The feedback is communicated to the learner via a set of virtual characters, each having its own competence [3]. A specific feedback thus incorporates three aspects: content, character appearance, and a didactic setting (e.g. Quiz mode). In the interactive event we will demonstrate the latest achievements of the DynaLearn project. First, the 6 learning spaces for learners to work with. Second, the generation of feedback relevant to the individual needs of a learner using Semantic Web technology. Third, the verbalization of the feedback via different animated virtual characters, notably: Basic help, Critic, Recommender, Quizmaster & Teachable agen
