João Olha-para-o-ar e Felipe Irrequieto: distúrbios da atenção e hiperatividade

A estruturação dos processos cognitivos, a partir das relações do sujeito com o meio, constitui a base para a aprendizagem. Dentre os diversos processos cognitivos, a atenção representa um mecanismo imprescindível para a compreensão e incorporação de novos conteúdos. Distúrbios do processo atencional, além de comprometer a aprendizagem, estendem-se para comportamentos de hiperatividade. Os distúrbios da atenção e a hiperatividade - fenômenos intimamente correlacionados - contribuem para que o sujeito tenha dificuldades significativas em outras funções cognitivas, como linguagem, cálculo, capacidade de reconhecimento e de planejamento, habilidade de autocorreção dos comportamentos, etc. O desempenho pedagógico por parte do professor, integrado à ação interdisciplinar de outros profissionais habilitados e de familiares, constitui uma estratégia promissora na abordagem e orientação da criança com distúrbios da atenção e hiperatividade.

O processo de formação de conceitos na perspectiva vigotskiana

In his work on human knowledge, Vygotsky reveals the second human nature, the one which is historical and cultural, due to people´s learning throughout life, through the mediation of others and the concrete conditions of life and education. In this eminently social process, the child grows into the intellectual life having the adult as a peer and learns human skills from this adult-child interaction. This means that, for working with abstract formulation, it is necessary understanding it as a complex, dynamic and functional act that is built by the insertion of individual performance into culture that is mediated by interaction with others. In this setting, each individual reaches knowledge through formal and non-formal learning that help on the formulation of scientific and everyday concepts. To make studies on the process of concept formation, Vygotsky adopted an experimental methodology based on the philosophical assumptions of Marxist theory of how mental processes occur, once he perceived these processes in a constantly changing and moving. Thus, the method called “Instrumental, Cultural and Historical” differed from conventional experimental studies focused on the performance of the task itself. The method adopted by Vygotsky was concerned with the process of concept formation and not only with fragmentary cutouts of cognitive processes. According to our study, the formation of the social nature of man develops from processes of appropriation and objectification of knowledge, which makes individual the historically constructed achievements by mankind, as, for example, types of sophisticated thinking, which requires the discussion of concept formation.

Estados emocionais em professores recém-formados: análise contextual

In general, the early career is a period marked by crises. Hubermam (1992) points out that this period is considered by the teacher as one of life's most difficult professional teaching. According to Machado (2004), the physical education worked only in competitive perspective in school, does not contribute to the school to perform its social role. This approach encourages the use of stigmas, labels and prejudices, so common in school, that marginalize even more students from lower classes, and can make the sport of high performance within the school walls create students with low self-esteem and low motivation within other possible disorders . Thus, this study presents the fundamental importance to aid and support to novice teachers, so that they can understand, and address key emotional aspects that interfere in their practice. Thus, our aim was to identify the most recurrent emotional processes in novice teachers identify and also how these emotional states can influence the professional and personal attitudes of these teachers. Through a bibliographic we seek statements, reports and case studies that provide enough material to our analysis and interpretation in order to collaborate with the study area and proceed to proposals that are not unreasonable or tied to the current system. Among the emotional states reported in the literature, we highlight the main, more present and influent in the beginner teacher as listed as follow: Anxiety, Stress, Fear, Shame, Low Self Confidence and Motivation. Considering these states, Damasio (1996) reports that the United Emotional directly influenced the style and efficiency of cognitive processes, in other words, interfere with the performance of teachers in the teaching front. Thus, Machado (2006) points out that the teacher should have a set of techniques and procedures that drive their practice in a manner appropriate to the leading group. Therefore, the knowledge of Psychology of Physical...

Um modelo cognitivo baseado na atenção para consciência em robôs inteligentes

Understanding consciousness is one of the most fascinating challenges of our time. From ancient civilizations to modern philosophers, questions have been asked on how one is conscious of his/her own existence and about the world that surrounds him/her. Although there is no precise definition for consciousness, there is an agreement that it is strongly related to human cognitive processes such as: thinking, reasoning, emotions, wishes. One of the key processes to the arising of the consciousness is the attention, a process capable of promoting a selection of a few stimuli from a huge amount of information that reaches us constantly. Machine consciousness is the field of the artificial intelligence that investigate the possibility of the production of conscious processes in artificial devices. This work presents a review about the theme of consciousness - in both natural and artificial aspects -, discussing this theme from the philosophical and computational perspectives, and investigates the feasibility of the adoption of an attentional schema as the base to the cognitive processing. A formal computational model is proposed for conscious agents that integrates: short and long term memories, reasoning, planning, emotion, decision making, learning, motivation and volition. Computer experiments in a mobile robotics domain under USARSim simulation environment, proposed by RoboCup, suggest that the agent can be able to use these elements to acquire experiences based on environment stimuli. The adoption of the cognitive architecture over the attentional model has potential to allow the emergence of behaviours usually associated to the consciousness in the simulated mobile robots. Further implementation under this model could potentially allow the agent to express sentience, selfawareness, self-consciousness, autonoetic consciousness, mineness and perspectivalness. By performing computation over an attentional space, the model also allows the ...

The Perception of Natural, Cell Phone, and Computer-Synthesized Speech During The Performance Of Simultaneous Visual-Motor Tasks

This study investigated the influence of top-down and bottom-up information on speech perception in complex listening environments. Specifically, the effects of listening to different types of processed speech were examined on intelligibility and on simultaneous visual-motor performance. The goal was to extend the generalizability of results in speech perception to environments outside of the laboratory. The effect of bottom-up information was evaluated with natural, cell phone and synthetic speech. The effect of simultaneous tasks was evaluated with concurrent visual-motor and memory tasks. Earlier works on the perception of speech during simultaneous visual-motor tasks have shown inconsistent results (Choi, 2004; Strayer & Johnston, 2001). In the present experiments, two dual-task paradigms were constructed in order to mimic non-laboratory listening environments. In the first two experiments, an auditory word repetition task was the primary task and a visual-motor task was the secondary task. Participants were presented with different kinds of speech in a background of multi-speaker babble and were asked to repeat the last word of every sentence while doing the simultaneous tracking task. Word accuracy and visual-motor task performance were measured. Taken together, the results of Experiments 1 and 2 showed that the intelligibility of natural speech was better than synthetic speech and that synthetic speech was better perceived than cell phone speech. The visual-motor methodology was found to demonstrate independent and supplemental information and provided a better understanding of the entire speech perception process. Experiment 3 was conducted to determine whether the automaticity of the tasks (Schneider & Shiffrin, 1977) helped to explain the results of the first two experiments. It was found that cell phone speech allowed better simultaneous pursuit rotor performance only at low intelligibility levels when participants ignored the listening task. Also, simultaneous task performance improved dramatically for natural speech when intelligibility was good. Overall, it could be concluded that knowledge of intelligibility alone is insufficient to characterize processing of different speech sources. Additional measures such as attentional demands and performance of simultaneous tasks were also important in characterizing the perception of different kinds of speech in complex listening environments.

Transcriptional Alterations Related to Neuropathology and Clinical Manifestation of Alzheimer's Disease

Alzheimer's disease (AD) is the most common cause of dementia in the human population, characterized by a spectrum of neuropathological abnormalities that results in memory impairment and loss of other cognitive processes as well as the presence of non-cognitive symptoms. Transcriptomic analyses provide an important approach to elucidating the pathogenesis of complex diseases like AD, helping to figure out both pre-clinical markers to identify susceptible patients and the early pathogenic mechanisms to serve as therapeutic targets. This study provides the gene expression profile of postmortem brain tissue from subjects with clinic-pathological AD (Braak IV, V, or V and CERAD B or C; and CDR >= 1), preclinical AD (Braak IV, V, or VI and CERAD B or C; and CDR = 0), and healthy older individuals (Braak <= II and CERAD 0 or A; and CDR = 0) in order to establish genes related to both AD neuropathology and clinical emergence of dementia. Based on differential gene expression, hierarchical clustering and network analysis, genes involved in energy metabolism, oxidative stress, DNA damage/repair, senescence, and transcriptional regulation were implicated with the neuropathology of AD; a transcriptional profile related to clinical manifestation of AD could not be detected with reliability using differential gene expression analysis, although genes involved in synaptic plasticity, and cell cycle seems to have a role revealed by gene classifier. In conclusion, the present data suggest gene expression profile changes secondary to the development of AD-related pathology and some genes that appear to be related to the clinical manifestation of dementia in subjects with significant AD pathology, making necessary further investigations to better understand these transcriptional findings on the pathogenesis and clinical emergence of AD.

Parallel modeling of the electric field distribution in the brain

The term "Brain Imaging" identi�es a set of techniques to analyze the structure and/or functional behavior of the brain in normal and/or pathological situations. These techniques are largely used in the study of brain activity. In addition to clinical usage, analysis of brain activity is gaining popularity in others recent �fields, i.e. Brain Computer Interfaces (BCI) and the study of cognitive processes. In this context, usage of classical solutions (e.g. f MRI, PET-CT) could be unfeasible, due to their low temporal resolution, high cost and limited portability. For these reasons alternative low cost techniques are object of research, typically based on simple recording hardware and on intensive data elaboration process. Typical examples are ElectroEncephaloGraphy (EEG) and Electrical Impedance Tomography (EIT), where electric potential at the patient's scalp is recorded by high impedance electrodes. In EEG potentials are directly generated from neuronal activity, while in EIT by the injection of small currents at the scalp. To retrieve meaningful insights on brain activity from measurements, EIT and EEG relies on detailed knowledge of the underlying electrical properties of the body. This is obtained from numerical models of the electric �field distribution therein. The inhomogeneous and anisotropic electric properties of human tissues make accurate modeling and simulation very challenging, leading to a tradeo�ff between physical accuracy and technical feasibility, which currently severely limits the capabilities of these techniques. Moreover elaboration of data recorded requires usage of regularization techniques computationally intensive, which influences the application with heavy temporal constraints (such as BCI). This work focuses on the parallel implementation of a work-flow for EEG and EIT data processing. The resulting software is accelerated using multi-core GPUs, in order to provide solution in reasonable times and address requirements of real-time BCI systems, without over-simplifying the complexity and accuracy of the head models.

Lo spazio senso-motorio come rappresentazione dei comportamenti intersoggettivi. Una nuova ipotesi sperimentale dalla filosofia alle neuroscienze

La ricerca ha preso le mosse da tre ipotesi fondamentali: 1) Esiste un legame tra processi cognitivi di basso ed alto livello; 2) Lo spazio senso-motorio è una percezione soggettiva; 3) Lo spazio senso-motorio varia in funzione delle diverse modalità di interazione sociale. La tesi sostiene che lo spazio senso-motorio si lascia modulare dalla semplice co-presenza di un altro agente umano e da interazioni cooperative e non cooperative. I capitoli I, II, III, hanno lo scopo di scomporre e spiegare il significato della prima, seconda e terza ipotesi; giungendo a formulare la tesi centrale che sarà poi dimostrata sperimentalmente nel capitolo IV. Il capitolo V introduce future linee di ricerca nell’ambito dell’etica proponendo una nuova ipotesi sul legame che potrebbe sussistere tra la percezione dello spazio durante l’interazione sociale e i giudizi morali. Il lavoro svolto chiama ad operare insieme diverse discipline che concorrono a formare le scienze cognitive: la storia della filosofia, la filosofia della mente contemporanea, la neuropsicologia sperimentale ed alcuni temi della psicologia sociale.
