Considerando a possibilidade de comprometimentos relacionados à contaminação por chumbo, como dificuldades e distúrbios na aprendizagem, falta de atenção, perda de memória e distúrbios de comportamento da criança, isto poderá comprometer também o seu desempenho escolar bem como levar a rotulações e a inadequações no tratamento nas diversas situações do dia-a-dia. Entendemos que a Psicologia pode contribuir para que tais situações, se ocorrerem, possam ser amenizadas através de avaliações e diagnósticos, buscando identificar as áreas de comprometimentos para que haja orientação de estratégias educacionais e estimuladoras efetivas para a otimização do desenvolvimento destas crianças.Este estudo foi realizado na cidade de Bauru (SP), com 40 participantes, de ambos os sexos, com idade de 07 a 10 anos, freqüentando o ensino fundamental. Divididos em 2 grupos de 20 crianças cada, examinadas pelo Instituto Adolfo Lutz, através de exames de sangue, sendo o G1 era composto por crianças consideradas não intoxicadas, com índice zero de chumbo no sangue; e o G2, por crianças com níveis de contaminação do sangue por chumbo superior a 10 æg/dl, (10 æg/dl - índice máximo suportável estabelecido pela OMS). Participaram também, os professores de ambos os grupos. Esta investigação se deu por meio da aplicação do instrumento WISC III e de questionário com os professores, abordando aspectos comportamentais e de desempenho escolar das crianças. Os resultados obtidos nos dois instrumentos utilizados neste estudo indicaram prejuízos maiores para a população contaminada, corroborando a literatura pesquisada sugerindo, entretanto, a necessidade de outros estudos para a confirmação destes resultados. / The present work has for objective to investigate alterations in the children's intellectual acting due to the contamination for lead. Considering the possibility of compromising's areas related to the contamination for lead, as difficulties and disturbances in the learning, lack of attention, loss of memory and disturbances of the child's behavior, this will also be able to commit your school acting as well as to take the label and to inadequacies in the treatment in the several situations of the day by day. We understood that the Psychology can contribute so that such situations, if they happen, they can be softened through evaluations and diagnoses, looking for to identify the compromising's areas so that there are orientation of educational strategies and stimulation effective for the improvement of the development of these children. This study it was accomplished in the city of Bauru, with 40 participants, of both sexes, with age from 07 to 10 years, frequenting the fundamental teaching. Divided in 2 groups of 20 children each, examined by the Institute Adolfo Lutz, through blood tests, being G1 composed by children not considered intoxicated, in agreement with established index for OMS; and G2, for children with levels of contamination of the blood for superior lead to 10 æg/dl (10 æg/dl - established maximum index for OMS). They also Participated, the teachers of both groups. This investigation felt through the application of the instrument WISC III and of questionnaire with the teachers, approaching behavior's aspects and of the children's school acting. The results obtained in the two instruments used in this study they indicated larger damages for the intoxicated population, corroborating the researched literature suggesting, however, the need of other studies for the confirmation of these results.

Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents in the US. Children and adolescents who sustain moderate and severe head injuries are much more likely to evidence significant deficits in neuropsychological functioning when compared with children with mild head injuries. Information about the recovery process and functional sequelae associated with moderate and severe head injuries remains limited, despite clear indications that children who experience such injuries typically exhibit notable deficits in intellectual functioning, particularly during the acute phase of recovery. Thus, the present study was conducted to augment research on intellectual functioning in children with moderate or severe head injuries. To accomplish this, the study first examined the proposed factor model of the WISC-III in children with moderate and severe TBI. Given high prevalence rates and similar trends in cognitive impairment, particularly within the frontal lobe structures (e.g., disrupted cognitive flexibility and divided attention), the study also examined this same factor model for a group of children with attention-deficit/hyperactivity disorder (ADHD) and compared it with the model fit from the TBI group. In the second phase of the study, both the TBI and AHDH groups were evaluated to determine if distinct WISC-III index score cluster profiles could be identified. Lastly, the cluster groups for both the TBI and ADHD samples were validated using important demographic and clinical variables, as well as scores from independent neuropsychological measures of attention, executive functioning, and working memory. Parent reports of psychological and behavioral functioning were also used in an attempt to further distinguish the cluster groups. Study limitations and future research implications were also discussed.

VISUAL MEMORY AS A DETERMINANT OF COMMUNICATIVE AND LEARNING COMPETENCIES IN PUPILS WITH HEARING IMPAIRMENT ABSTRACT: This submitted work concentrates on visual perception, especially on visual memory and related attention in children and pupils with hearing impairment, which from the theoretical point of view represents the most important compensatory sense for this group of people. The main part of the submitted paper consists in presenting the results of a research survey observing the levels of visual perception and attention in children and pupils in the age group 6 to 8 years old, as well as on comparing them with results achieved by a group of hearing children and pupils of the same age range. We chose four subtests focused on the current state of visual memory and attention. These subtests constitute a part of two standardized tests. The following analysis of the gained data was used to validate our hypotheses regarding the influence of the compensatory mechanism applied when processing visual inputs by people with hearing impairment existing on the level of the central nervous system. Furthermore, the paper provides processed and commented data gained from questionnaires destined for teachers. These questionnaires pursue the evaluation of communicative and learning competencies of the tested study...
