O transtorno do espectro autista (TEA) é um transtorno de desenvolvimento que prejudica persistentemente a comunicação e a interação social e causa padrões restritos e repetitivos de comportamento, interesses e atividades. Esses sintomas estão presentes desde o início da infância e limitam ou prejudicam o cotidiano do indivíduo. Contudo, vários fatores impedem que seja possível diagnosticar antes dos três anos de idade, entre eles o fato de que o diagnóstico é essencialmente clínico e realizado com base nos critérios descritos no Manual diagnóstico e estatístico de transtornos mentais da sociedade americana de psiquiatria (DSM), entrevistas com os pais, observação do comportamento e aplicação de questionários e escalas padronizadas. Estas ferramentas e questionários para a realização do diagnóstico ainda carecem de validação e adaptação ao contexto brasileiro. O estudo das características antropométricas em indivíduos com TEA e indivíduos em desenvolvimento típico mostrou que podem existir diferenças como distâncias entre as pupilas, formato das orelhas, estrabismo e circunferência da cabeça. A hipótese é que seria possível classificar indivíduos com TEA e indivíduos em desenvolvimento típico com base nas medidas antropométricas faciais. Desta forma, este trabalho teve como objetivo a construção de um classificador que, dada uma imagem facial de uma criança, consiga discriminar entre os dois grupos, auxiliando assim o diagnóstico. A fim de testar a hipótese, foram coletadas imagens bidimensionais de crianças e adolescentes com TEA e em desenvolvimento tipico para a construção de uma base de dados. As imagens foram processadas por meio de um pipeline definido neste trabalho e foram testados e comparados diferentes métodos de redução de dimensionalidade e classificação e como resultado obteve-se acurácia de 80% na classificação com Random Forests / Autism Spectrum Disorder (ASD) is a developmental disorder that persistently impairs communication and social interaction and causes restricted and repetitive patterns of behavior, interests, and activities. These symptoms are present from the beginning of childhood and limit or impair the daily life of the individual. However, several factors prevent it from being possible to diagnose before the age of three, including the fact that the diagnosis is essentially clinical and performed based on the criteria described in the Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatry Association (DSM) , interviews with parents, observation of behavior and application of questionnaires and standardized scales. These tools and questionnaires to carry out the diagnosis still lack validation and adaptation to the brazilian context. The study of anthropometric features in individuals with ASD and individuals in typical development showed that there may be differences such as distances between the pupils, ear format, strabismus and head circumference. The hypothesis is that it would be possible to classify individuals with ASD and individuals in typical development based on anthropometric facial measures. Therefore, this work aimed to construct a classifier that, given a childs facial image, can discriminate between the two groups, thus helping the diagnosis. In order to test the hypothesis, two-dimensional images of children and adolescents with ASD and in typical development were collected for the database construction. The images were processed in a pipeline defined in this work and different methods of dimensionality reduction and classification were tested and compared and as a result 80% accuracy was obtained in the classification with Random Forests algorithm

Stability of diagnosis, symptoms and functioning across the life span is central to understanding any disorder and yet remains a relatively unexplored area in the study of autism (Sigman & McGovern, 2005). This is particularly apparent in the development of communication, including social interaction and language development in children with autism spectrum disorder (ASD), as there is little research on longitudinal development of children with ASD in general. The outlook on ASD has changed throughout the years, and although the emphasis on speech delay and communication problems have been separated from ASD, it is still one of the most common causes of initial referral in autism diagnoses (Pickles, Risi & Lord, 2004). Understanding the trajectory of communication for a child with ASD is fundamental in providing support and intervention in early years development. As communication is also a primary indicator on later development, it can gage outcomes into adaptive skills, school achievement and adult independence in later adult life. Eleven articles were identified in order to systematically review longitudinal studies based on communication development in ASD, or lack thereof, and why it is important to further carry out research in this area. This review seeks to explore: 1. How the development of different communicative functions in children with ASD is related to change over time. And, 2. What aspects of the child’s proximal processes and/or the child’s characteristics are discussed during measurement periods. Communicative functions were the most common form of communication observed in the studies at assessment periods and as for time points; two assessment periods were most common showing a linear trajectory of progress or decline from time point 1 and 2. All studies discussed aspects of child characteristics, most predominantly being gender and I.Q., however lacked insight into the significance of these and factors of proximal process during measurement periods in the studies reviewed. Ultimately, results display a need for more studies with at least three time points. With two time points only comes a “before” and “after” perspective, whereas, three or more time points enables collection of waves of data, showing key predictors of change in communication in children with a form of ASD.

The general purpose of the current study was to evaluate the effects of minimally intrusive prompting procedures and preferred stimuli on protodeclarative joint attention initiations in children diagnosed with autism spectrum disorder (ASD). Two boys and one girl diagnosed with ASD participated. The experimenter provided attention and social interaction following protodeclarative initiations throughout all phases of the study. During intervention, a model prompt was delivered every 30 s if the participant failed to initiate a bid for joint attention. Results for the first participant show that a model prompt was sufficient to increase the rate of protodeclarative initiations across stimulus sets. Generalization was seen across sets, but not across environments. Subsequently, the model prompt was sufficient to increase the rate of protodeclarative initiations across sets in a second setting (classroom). Results for the second participant are inconclusive. Data collected during the initial baseline condition show that she engaged in an incompatible verbal response across sets. When pictorial stimuli depicting highinterest items and activities were introduced, the rate of protodeclarative initiations increased over time. We then returned to original baseline condition and saw an initial decrease, followed by a steady increase in the rate of protodeclarative initiations. The third participant withdrew prematurely due to medical reasons. The findings of the current study show that minimally intrusive prompts and natural consequences may be sufficient to establish protodeclarative initiations in children. However, this finding may be limited to only those children for whom social interactions already function as reinforcers.

This study compared the relative reinforcing efficacy of high-preferred and low-preferred stimuli, as determined by two types of preference assessments, on acquisition rates in three children diagnosed with an Autism Spectrum Disorder (ASD). The study also evaluated the indirect effects of preference on students’ stereotypy and problem behavior during instructional periods. Participants were presented with a task and provided high or low-preferred stimuli contingent upon correct responding. Results showed that acquisition occurred more rapidly in the highly preferred condition for some participants. Higher rates of problem behavior occurred in the low preferred condition for all participants. These results highlight the importance of utilizing preference assessment procedures to identify and deliver high-preferred items in skill acquisition procedures for individuals with ASD.

Conclusion: The results suggest that ASD children have deficits in attentional and inhibitory control. Frontal dysfunction and weak ACC engagement in ASD were supported as the underlying neuronal inefficiency. / Methods: 20 children with high-functioning ASD [Mean Age (SD): 10.75 years old (2.07 years); Mean IQ (SD): 101.4 (16.8)] and age- and IQ-matched normal children (NC) [Mean Age (SD): 9.80 years old (1.88 years); Mean IQ (SD): 110.7(17.8)] were investigated electrophysiologically during performance of a visual Go/NoGo task. An electrophysiological source localization method was employed to further analyze the data. Several different neurospsychological tests were also performed to provide behavioral measures on attention and inhibition. / Objectives: To investigate neurophysiologic abnormalities in frontal and anterior cingulate cortex underlying attentional and inhibitory control in children with Autism Spectrum Disorder (ASD). / Results: ASD children showed a significantly task-related lower frontal theta activity. This effect was associated with a significantly reduced activation of the anterior cingulate cortex (ACC). Both groups also differ significantly regarding the behavioral aspects of attention and inhibition. / Leung, Shuk Yin Connie. / "November 2009." / Adviser: Chan Sue-Yin Agnes. / Source: Dissertation Abstracts International, Volume: 72-01, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 65-85). / Electronic reproduction.

O Transtorno do Espectro Autista (TEA) inclui em seu diagnóstico diversos sintomas, apresentando uma ampla variedade nos níveis de desenvolvimento e funcionamento. Embora não central ao diagnóstico, diversos pesquisadores têm associado déficits motores e dispraxia a esse diagnóstico. Além disso, tem-se associado prejuízos funcionais decorrentes da dispraxia em crianças com TEA. Na literatura são poucos os estudos que avaliam dispraxia em crianças com TEA, nenhum destes estudos no Brasil. Assim, nosso objetivo foi verificar se as crianças com TEA apresentam um perfil de dispraxia característico. Para isso realizamos coleta com 03 grupos distintos, cada um composto por 30 crianças, foram eles: TEA (G-TEA) nível 1, Síndrome de Down (G-SD) e controle (G-C). Para avaliação da praxia, optamos pelo teste Sensory Integration and Praxis Test (SIPT), que avalia diversas funções de praxia e já foi utilizado em estudos com a população alvo de nosso estudo. Além disso, utilizamos a Escala de Comportamento Adaptativo Vineland (para verificar o nível adaptativo dos indivíduos participantes), escala de Avaliação de Traços Autísticos (ATA) para sustentação diagnóstica do G-TEA e utilizamos a Escala de Classe Social de Pelotas, para verificar se a classe social teria impacto na amostra. Como resultado, as crianças do G-C apresentaram escores dentro da faixa de normalidade, sendo todos os escores positivos, as crianças do G-TEA apresentaram escores mais baixos do que o G-C, no entanto, apenas em 07 dos 17 testes tiveram prejuízos, com desempenho abaixo do normal, sendo estes testes relacionados à praxia (imitação de posturas, movimentos e oral, além de praxia sem indicação visual), função vestibular (equilíbrio e nistagmo) e, estereognosia. As crianças do G-SD apresentaram desempenho abaixo do normal em todos os testes aplicados, possivelmente isso é decorrente da comorbidade da síndrome com deficiência intelectual. Além disso, encontramos uma diferença significativa maior no escore da Vineland relacionado à Atividade de Vida Cotidiana, ao compararmos crianças com TEA com grupo controle. Estudos corroboram o achado em nossa pesquisa, indicando que, crianças com TEA apresentam dispraxia que parece ser característica deste transtorno. Alguns estudos encontraram que as crianças com TEA apresentam prejuízos nas mesmas áreas dos encontrados por nós. Os profissionais embora defendam a intervenção com essas crianças, têm usado poucas avaliações que justifiquem tais intervenções, dessa forma, acreditamos que é importante o uso de instrumentos para avaliação da praxia em crianças com TEA, visando direcionar o planejamento terapêutico e ganhos funcionais para essas crianças / Autism Spectrum Disorder (ASD) includes in its diagnostic several symptoms, with a wide variety in the levels of development and functioning. Although motor deficits and dyspraxia are not relevant to the diagnosis, several researchers have done this association. In addition, functional impairments due to dyspraxia have been associated in children with ASD. In the literature, there are few studies evaluating dyspraxia in children with ASD none of these studies in Brazil. Our aim was to verify if children with ASD have a characteristic dyspraxia profile. To do this, we performed a collection of three different groups, each composed of 30 children: ASD (G-ASD) level 1, Down Syndrome (G-DS) and control (G-C). In order to evaluate praxis, we decided to use the Sensory Integration and Praxis Test (SIPT), which evaluates several praxis functions and has already been used in studies with the target population of our study. In addition, we used the Vineland Adaptive Behavior Scale (to verify the adaptive level of the participants), Autistic Trait Scale (ATA) for diagnostic support of G-ASD and used the Pelotas Social Class Scale to verify if social class would have an impact on the sample. As a result, G-C presented scores within the range of normal, and all scores were positive, G-ASD children presented lower scores than GC, however, only in 07 of 17 tests with performance below of the normal, being these tests related to praxis (imitation of postures, movements and oral, besides praxis without visual indication), vestibular function (balance and nystagmus) and stereognosis. The G-DS children presented below-normal performance in all applied tests, possibly due to the comorbidity of the syndrome with intellectual disability. In addition, we found a major significant difference in the Vineland score related to Daily Living Activity, when comparing children with ASD with the control group. Studies corroborate the finding in our study, indicating that children with ASD have dyspraxia that appears to be characteristic of this disorder. Some studies have found that children with ASD has same difficulties that we found. Although practitioners advocate intervention with these children, they have used few evaluations instruments to justify such interventions, so we believe that it is important to use instruments to assess praxis in children with ASD, in order to direct the therapeutic planning and functional gains for these children

Esta pesquisa tem como finalidade produzir uma contribuição teórica sobre os processos formativos dos professores para a educação de alunos com diagnóstico de autismo, no âmbito das Políticas de Educação Inclusiva. Delimita-se como objetivo compreender os sentidos pessoais constituídos nesse processo e a sua relação com a organização das práticas pelos professores. O referencial teórico metodológico da pesquisa fundamenta-se nos princípios do materialismo histórico dialético, no que se refere à concepção de homem, de ciência e à perspectiva de explicar a realidade e as possibilidades concretas para a sua transformação. Foi realizada uma pesquisa de campo sobre os sentidos pessoais atribuídos pelos professores em atividades formativas em uma escola pública de São Bernardo do Campo (SP), durante 2014. O desenvolvimento da pesquisa envolveu: reuniões com a diretora e as coordenadoras pedagógicas da unidade escolar para discussões sobre as ações formativas previstas no Projeto Político-Pedagógico de 2014; entrevistas semiestruturadas, em grupo e individualmente, com quatro professores de alunos com diagnóstico de autismo, visando apreender o sentido pessoal atribuído nas atividades formativas vivenciadas; consulta a documentos referentes à organização dos momentos formativos desenvolvidos no âmbito escolar, às situações de acompanhamento das atividades pedagógicas e acerca de um curso sobre autismo ofertado pela Secretaria de Educação no mesmo período; e, por fim, para a compreensão do fenômeno em sua totalidade, buscaram-se também informações sobre a organização da educação inclusiva no sistema educacional no qual está inserida a escola onde ocorreu a pesquisa e sobre a constituição da conceituação de autismo na sociedade, a fim de tornar possível a discussão das inter-relações vividas no sistema. No movimento final da pesquisa, tendo-se por referência constructos da Teoria Histórico-Cultural sobre a estrutura das atividades humanas, foi possível analisar as ações formativas geradoras de sentido, ainda que parcialmente, para os professores participantes das discussões sobre a educação inclusiva envolvendo alunos com Transtorno do Espectro Autista. Como resultado do estudo, defende-se que os processos formativos desencadeiam transformações nas práticas pedagógicas se ações articuladas possibilitarem a significação da finalidade do ensino envolvendo alunos com TEA, sustentada pela concepção de educação como instrumento mediador do processo de desenvolvimento humano e pela compreensão do papel da constituição da linguagem. Tais ações precisam necessariamente articular a organização do ensino, o conhecimento teórico e a constituição de uma coletividade de estudo. / This research has the purpose to produce a theoretical contribution about the formation processes for teachers of students diagnosed with Autism that has being developed in the Inclusive Education Policies. It is defined as objective for the study understanding the personal senses elaborated in the process and their relationship with the organization of practices by teachers. The referential theoretical methodological of the research is based on the principals of the Dialectical Historical Materialism with regard to the conception of human, of the science and of the prospect of explaining reality and the concrete possibilities for transformation. It was conducted the field research on the personal senses attributed by teachers into formative activities in a public school of São Bernardo do Campo (SP), during 2014. The development of research involved meetings with the director and educational coordinators of school unit for discussions about the formative activities set out in the Pedagogical Political Project of 2014; semi-structured interviews, in groups or individually, with four teachers of students with autism diagnosis in order of apprehending the personal sense attributed during the formative activities; consultation of documents concerning the organization of formative moments developed in the school, on the accompanying situations of educational activities and about a course on autism offered by the Education Department in the same period; and finally, to understanding the phenomenon in its entirety, it were researched information about the organization of inclusive education in the public system in which it operates the school where occurred the research and on the meaning of autism in society, in order to be possible to discuss their interrelations with the teacher\'s personal senses. In the final movement of research, having by reference the constructs of the HistoricCultural Theory about the structure of human activities, it was possible to analyze the activities that generate personal senses, even partially, for the teachers participating in the discussions on inclusive education involving Students with Autism Spectrum Disorder. As a result of the study it is argued that the teacher education processes trigger changes in teaching practice if they have articulated actions that allow the definition of the purpose of educational activity involving students with ASD, supported by a human development conception and for understanding the role of constitution language. Such actions necessarily articulate the organization of teaching, the theoretical knowledge and the formation of a studying collective.

Os Transtornos do Espectro Autista (TEA) são categorizados como um transtorno do neurodesenvolvimento caracterizados por demonstrar anormalidades no desenvolvimento social e na comunicação e padrões restritos de comportamentos e interesses desde idades muito precoces. Considerado um transtorno com causas multifatoriais e um quadro clínico bastante característico, tem despertado o interesse de profissionais de diversas áreas do conhecimento, com o propósito de entender e identificar as prováveis causas que ocasionam as mudanças na estruturação, organização e funcionamento durante todo o processo de desenvolvimento. O autismo seria uma desordem da empatia, aliada a uma capacidade média ou mesmo superior de sistematização, o que traria como consequência um cérebro extremamente masculino. O objetivo deste trabalho foi verificar se as crianças com TEA apresentam um cérebro com características extremamente masculinas, como proposto pela teoria anteriormente citada, avaliando as diferenças existentes na formação da identidade de gênero em crianças com Transtorno do Espectro Autista, em crianças normais e em crianças com Retardo Mental. O estudo empírico foi desenvolvido com delineamento transversal numa amostra de 99 crianças do sexo masculino e idades entre quatro e seis anos e 6 meses, provenientes de cidades dos Estados de São Paulo e da Bahia. As crianças foram divididas em três grupos, considerando suas características clínicas: Grupo Controle crianças com desenvolvimento considerado normal (n=33); Grupo Clínico crianças com Transtornos do Espectro Autista TEA (n=33) e Grupo Clínico crianças com Retardo Mental RM (n=33). Os instrumentos utilizados foram a Escala de Traços Autísticos ATA, a Escala Mental Colúmbia e o Teste de Apercepção de Gênero - TAG. Foram identificadas diferenças significativas nos resultados apresentados pelos três grupos, em relação à aquisição da identidade de gênero, com o grupo controle apresentando um maior índice de escolhas de itens masculinos, seguido pelo grupo clínico TEA e o grupo clínico RM. As diferenças identificadas estão diretamente relacionadas às características clínicas das crianças que compuseram os grupos. Ao lado disso, observou-se que o grupo clínico com TEA além de não ter obtido o melhor desempenho, em relação ao grupo controle, também apresentou diferenças em relação ao processo de aquisição de identidade de gênero quando comparadas ao grupo clínico RM / The Autism Spectrum Disorders (ASD) are categorized as a neurodevelopmental disorder in which an individual demonstrates abnormalities in social development, communication, and in restricted patterns of behaviours and interests from very early ages. Considered to be a disorder with multifactorial causes and a clinical picture quite characteristic, it has aroused the interest of professionals from various fields of knowledge with the purpose to understand and identify the causes that are most likely involved in changes of structure, organization, and functioning during the whole process of development. This implies the consideration of different theoretical, methodological, and practical positions that contribute to advance our understanding of the phenomenon. Autism would be a disorder of empathy, allied to an average capacity or even superior of systematization, which would bring, as consequence, a brain extremely masculine. Then, this study aimed to verify whether the children with ASD present a brain with extremely masculine characteristics, as proposed by the theory aforementioned, through the assessment of differences regarding the formation of gender identity in children with Autistic Spectrum Disorders, in children with typical development, and in children with Mental Retardation. The empirical study was developed as a cross-sectional design, with a sample of 99 male children and aged four to six years and 6 months, from cities of the states of Sao Paulo and Bahia. This sample was divided into three groups, considering their clinical features: Control group children in typical development (n=33); Clinical group children with Autistic Spectrum Disorders ASD (n=33) and Clinical group children with Mental Retardation RM (n=33). The instruments used were the Assessment Scale of Autistic Traits ATA, the Columbia Mental Maturity Scale and the Gender Apperception Test GAT. Significant differences were identified in the results provided by the three groups regarding the gender acquisition, with the Control Group presenting a higher score in masculine items, followed by the group with TEA and then the MR group. The identified differences are directly related to the clinical features of the children that composed the groups. Furthermore, the ASD group besides not having obtained the best performance, in relation to the control group, it also presented differences as to the process of the gender identity acquisition when compared to the MR group

In the tradition of acceptance and commitment therapy (ACT), cognitive fusion is a transdiagnostic risk factor and occurs when one becomes overly attached to or "caught up" in their thoughts, leading to a more narrowed behavioral repertoire and difficulty taking effective action in response to life's demands. Cognitive defusion is ACT's curative answer to fusion, and denotes the process of taking a step back, seeing thoughts as "simply thoughts," thereby reducing the negative impact of distressing or anxiety-provoking thoughts. While these components have been widely studied in neurotypical (NT) samples, the purpose of this study was to extend findings to people diagnosed on the autism spectrum (AS). Specifically, this study aimed to examine the impact of cognitive fusion in this population and the effectiveness of a brief defusion technique. Forty-two AS participants and fifty-five neurotypical participants were given a battery of questionnaires measuring psychological distress and dispositional levels of cognitive fusion. Participants were then randomized into either a brief cognitive fusion technique or a brief active distraction technique. In both conditions participants chose a distressing thought and rated it on a visual analogue scale (VAS) in terms of thought discomfort and believability. They were then read a rationale regarding their assigned technique, practiced the technique, and applied the technique to their chosen distressing thought. After the intervention participants immediately re-rated the thought on the same VAS. Throughout the study, participants' heart rate and skin conductance were monitored to determine physiological effects of the conditions. Finally, a follow-up survey was sent at a one-week and two-week follow-up, where participants re-rated the believability and discomfort of their thoughts. Results of this study showed that the AS group had higher overall levels of fusion than the NT group, and that fusion was moderately to strongly related to psychological distress in the AS group and the NT group. In terms of the intervention effects, all interpretation statements must be taken with caution, as there were significant pre-group differences despite randomization. Both defusion and distraction worked equally well in immediately reducing thought believability and thought discomfort for AS and NT groups. Furthermore, treatment effects were maintained at the two-week follow-up period for all groups except for the AS group in the defusion condition. There were no treatment effects for physiology. The current study provides evidence that cognitive fusion may be an important factor in the psychiatric comorbidity that people with AS experience, and a brief technique can be effectively used.

Individuals with Autistic Spectrum Disorders (ASD) often perform better than typically developing (TD) individuals in simple, albeit difficult, visual search tasks. This ability is often attributed to a lack of drive for coherence or superior local processing. We compare thirty adults with ASD with forty-nine TD individuals and twenty-seven adults with anxiety (ANX) across two real-world visual search tasks. Individuals had to find either a number superimposed over a real-world scene ("œno context" condition) or an object located in a contextually relevant location ("œcontext" condition). Each participant completed forty-one trials in each condition, each with a unique scene. Eye movements were recorded using an SR Research EyeLink 1000 eyetracker. All groups performed better in the context condition. However, the ASD group was less accurate than both groups, across conditions. All groups were quicker to find the target in the context condition but the ASD group was slower than the TD group. Furthermore, the ASD group took longer to initiate their search, fixate on the target, and decide that they had found the target than the TD group. These results suggest that individuals with ASD are able to integrate contextual information to aid the search but that their previously seen visual search advantage may not transfer to visual searches of real-world scenes.
