Information processing and higher psychological functions in the disconnected hemispheres of human commissurotomy patients

Several patients of P. J. Vogel who had undergone cerebral commissurotomy for the control of intractable epilepsy were tested on a variety of tasks to measure aspects of cerebral organization concerned with lateralization in hemispheric function. From tests involving identification of shapes it was inferred that in the absence of the neocortical commissures, the left hemisphere still has access to certain types of information from the ipsilateral field. The major hemisphere can still make crude differentiations between various left-field stimuli, but is unable to specify exact stimulus properties. Most of the time the major hemisphere, having access to some ipsilateral stimuli, dominated the minor hemisphere in control of the body.

Competition for control of the body between the hemispheres is seen most clearly in tests of minor hemisphere language competency, in which it was determined that though the minor hemisphere does possess some minimal ability to express language, the major hemisphere prevented its expression much of the time. The right hemisphere was superior to the left in tests of perceptual visualization, and the two hemispheres appeared to use different strategies in attempting to solve the problems, namely, analysis for the left hemisphere and synthesis for the right hemisphere.

Analysis of the patients' verbal and performance I.Q.'s, as well as observations made throughout testing, suggest that the corpus callosum plays a critical role in activities that involve functions in which the minor hemisphere normally excels, that the motor expression of these functions may normally come through the major hemisphere by way of the corpus callosum.

Lateral specialization is thought to be an evolutionary adaptation which overcame problems of a functional antagonism between the abilities normally associated with the two hemispheres. The tests of perception suggested that this function lateralized into the mute hemisphere because of an active counteraction by language. This latter idea was confirmed by the finding that left-handers, in whom there is likely to be bilateral language centers, are greatly deficient on tests of perception.

Effect of different exercise programs on the psychological and cognitive functions of people with Parkinson's disease

The purpose of this study was to analyze the effect of different exercise programs on the psychological and cognitive functions in patients with Parkinson's disease (PD). Forty-five patients with PD participated in the study. The participants were randomized in three intervention programs: Group-1 (n=15, cognitive-activities), Group-2 (n=15, multimodal exercise) and Group-3 (n=15, exercises for posture and gait). The clinical, psychological and cognitive functions were assessed before and after 4 months of intervention. Univariate analysis did not reveal significant interactions between groups and time (p>0.05). However, univariate analysis for time revealed differences in stress level and memory. Participants showed less physical stress (p<0.01) and overall stress (p < 0.04) and higher performance in episodic declarative memory (p < 0.001) after exercise. These findings suggest that group work with motor or non-motor activities can improve cognitive and psychological functions of patients with PD.

A dimensão social do desenho: um estudo sobre as interações no processo de (re) construção imagética da criança no Ensino Fundamental

In the historical-cultural perspective, the drawing is processed by means of a shared and complex way, under diverse relations with the other and with the immersed signs of the culture. That is, something constituted by the social interactions and that can modify the structure of the psychological functions, therefore as socialized sign, propitiates the incorporation of the functions socially. In this way, the figuration carrier sensitive and established meanings historically disclosing the shared experiences and the ways of the subject to think and perceive the world. Such reflections gave shape to the main problem of this research: how to think over about the drawing at the school to incide in the reconstruction of the childs imaginative language? Under such perspective, this work deals with the interactions in the production process of the drawing of the children in a context of teach-Iearning of the elementary school having as goal to analyze the interactions established in the cIassroom in the process of production of the drawings; to propose situations of learnings that favor the advance graphical expression of the students; and to identify in the interactive games some relations between body expression and drawing. For its accomplishment, it was opted for the construction process based in the collaborative investigation by the fact to propitiate negotiations, sharing and confrontation of ideas, becoming possible a joint construction of the knowledge. For this research, the researcher and the collaborating teacher, as well as the involved children, become themselves into co-authors of the context studied. As locus of the research, it was chosen a first cycle class, with 30 students, from Municipal School Profª. Emília Ramos (Natal/RN - Brazil), whose election took in account the fact of this school to constitute in a promotional space of reflections and professional development of teachers in service and, at the same time, for presentinglimitations theoretic- methodological in the field of teaching for Arts. In the process of the research, it was perceived that the children with the support of the verbal language formulates meanings on the seen and imagined object, printing lines and forms that if overlap to the physiological aspects of the visual perception. That is, the drawing discloses a reality appraised, enriched for the picked up vision of the image, but the meanings established for the author, or observer who becomes it perceivable and identified. In the systemizing situations, it was observed that the teaching-Iearning process of the drawing, implies a co-construction between teachers and learners. And, moreover, the necessity to interlace emotion and cognition by means of plastic-corporal interactions that foment drawing experiences, whose process concurs for the imagenative reconstruct of the apprentices

Transtorno de déficit de atenção/hiperatividade e psicologia histórico-cultural

O Transtorno de Déficit de Atenção e Hiperatividade tem sido evocado como justificativa corrente para o fracasso escolar de um número expressivo de crianças, atribuindo-se a elas a responsabilidade por não aprender e isentando de análise a escola e a sociedade nas quais estão inseridas. A situação se torna mais alarmante uma vez que a literatura a respeito aponta dificuldades no diagnóstico e na intervenção sobre esse tipo de transtorno, devidas à falta de clareza sobre o que é esse quadro clínico e em razão da não existência de estudos consistentes acerca das consequências futuras do uso de estimulantes nas crianças. Para discutir essas questões, a primeira parte do artigo apresenta a concepção hegemônica desse tipo de transtorno e sua compreensão do psiquismo infantil. A segunda parte aborda a maneira como a psicologia histórico-cultural analisa o desenvolvimento da atenção e o controle voluntário do comportamento humano, redimensionando a compreensão sobre o transtorno. Finalmente, são feitas algumas reflexões acerca do processo ensino-aprendizagem em crianças com desenvolvimento parcial das funções psicológicas superiores e do papel da psicologia e da pedagogia na compreensão do fenômeno para que sirvam de subsídio a medidas práticas em relação ao problema.

Contribuições da teoria histórico-cultural para o processo de avaliação psicoeducacional

Cet article a comme objectif présenter la contribution de la Psychologie Historique-Culturelle pour l'analyse critique de l'évaluation psychoéducationnel traditionnel et postuler les fondements pour la nouvelle modalité évaluative. Cette proposition se justifie à cause de l'actuelle révitalisation de l'usage des testes padronisés pour la mensuration des fonctions psychologiques, dues à la vulgarisation de la neuropsychologie. Historiquement les testes padronisés servent comme instrument pour attester cientifiquement l'idéologie de l'égalité entre les hommes dans la societé capitaliste que se maintient à travers de l'expropriation et de l'exclusion. En outre, il existe une forte tendence à attendre que les résultats expliquent l'intelligence comme inée ou considèrent les prédispositions héréditaires pour apprendre, ce qu'on oppose à la comprehénsion que les fonctions mentales sont formées dans le proccès de développement historique-social à travers l'appropriation de la culture humaine. Il est nécessaire donc une évaluation qui considère les médiations sociales (des instruments et des signes) comme constituants des fonctions psychologiques encourageant le développement de tous les individus et la non légitimation de l'exclusion sociale.

O ensino da escrita e o desenvolvimento das pessoas com deficiência intelectual

This article proposes a theoretical reflection on the development of children with intellectual disabilities, regarding the importance and necessity of the process of learning the written language, from a historical-cultural point of view. For this approach, the course of development of a child disabled or not will occur according to cultural and social conditions experimented by him or her. Therefore, concerning the child with intellectual disabilities, his cultural condition, in dynamic relationship with the obstacles placed in its special condition, will be the source of his development. If the development of higher psychological functions is realized through the use of tools and if the people with intellectual disabilities present an inability to use these tools, there will be the need for aids so they can learn to use them in order to train and develop their psychic functions. In this process, education and written language acquisitions are fundamental ways of accessibility to the cultural world, a wider significance of communication in the world and to oneself. In short, the educators' comprehension about the importance of intentional teaching of written language and the historical process that envolves its development represents a fundamental contribution to the process of humanization of children with disabilities.

A alfabetização sob o olhar da Teoria Histórico Cultural: sobre a necessidade e a atividade de estudo

Studies on activity and learning in the cultural-historical approach involves, most cases, the discussions on the higher psychological functions and areas of proximal and real development. Having said that our objective in this paper is to make a discussion about the activity of study and the concepts that involve the teaching of the mother language from the Historic-Cultural theory. We point this way, the importance of this approach in studies on literacy and knowledge of the activity of study as central to the creation of humanizing need of reading and writing, starting from the principle that the creation of needs requires the production of discourses, which have their materiality in the text.

As artes na educação integral: uma apreciação histórico-crítica

The present work aims to draw some reflections on the role of art in integral education, particularly of art as a school subject. The paper focuses on the contribution of art to the development the individual and the higher psychological functions. The arguments presented here are based on the studies on art made by Lev Vygotsky and Georg Lukács and also on the educational studies made by Dermeval Saviani. We expect to contribute to the defense of the necessity of an integral education in which art, integrated with science and philosophy, opposes itself to the predominantly fetishistic and unilateral character of the activities that constitutes the life in the contemporary capitalist society.

Educação escolar e constituição do afetivo: algumas considerações a partir da psicologia histórico-cultural

Cultural-Historical Psychology alleges the thesis of social experience as the basis of human formation and points the affective-cognitive unity as the intermediate in subject relations with the knowledge on the development of psychological functions. This article presents some elements that indicate the constitution of affective processes from the relations the subject maintains with human objectifications. Part of the critics to the organismic and subjectivist thought that, both in Psychology and in Education, separates emotions from other functions of human consciousness – treating them as deterrents in the teaching and school learning processes – and signs the importance of (re) thinking the relations the subject establishes with reality, the role of knowledge and of the concrete conditions of life and education that produce the affective processes. It defends that thinking and feeling are psychological processes developed from history of appropriation and objectification of signs and instruments that each subject realizes and affirms in scholar education, and the intentional character of teaching – in the organizational and pedagogical practice – as determinant elements in the transformation of the ways of thinking and feeling.
