Available in PDF, EPUB and Kindle. Book excerpt: Discrepant findings on whether children with autism display response inhibition deficits may be partially due to the wide variety of behavioral tasks used to assess inhibition. A more useful way of understanding early cognitive/attentional processes that influence response inhibition may be to look at neurophysiological measures. Specifically, the event related potential N2, a measurement of cognitive control or the effortful decision to inhibit a prepotent behavioral response, may be useful in understanding the discrepancy in response inhibition. In the current study we measured the N2 as high-functioning autistic children and age, IQ-matched control children performed a modified Flanker task. We further examined the associations between N2 amplitude and latency and variations in social communication within the HFA sample. Behavioral and electrophysiological data from a modified Flanker task were collected from 27 HFA (1 female) and 24 typically developing controls (1 female) ranging in age from 8- to 16-years. Symptom severity was measured using the ASSQ, ADI, and SCQ. Regarding behavioral performance, HFA children committed more errors than control children when controlling for age and verbal IQ. Electrophysiological performance indicated marginal group differences in N2 amplitude when controlling for age. Typical age-related decline in N2 amplitude was observed in the control group but not in the HFA group. There were no significant group differences found for N2 latency. In addition, greater N2 amplitude was correlated with lower scores on the SCQ for the HFA children. Behavioral performance does not conclude that the HFA children show deficits in inhibition, but deficits regarding impulsivity. Electrophysiological data suggest developmental change in N2 amplitude differentiates the HFA and control groups. Finally, the relationship between larger N2 amplitude and lower scores on the SCQ, within the HFA children, indicate that social communication deficits are less when greater cognitive effort is utilized.
Book Synopsis Handbook of Executive Functioning by : Sam Goldstein
Download or read book Handbook of Executive Functioning written by Sam Goldstein and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planning. Attention. Memory. Self-regulation. These and other core cognitive and behavioral operations of daily life comprise what we know as executive functioning (EF). But despite all we know, the concept has engendered multiple, often conflicting definitions and its components are sometimes loosely defined and poorly understood. The Handbook of Executive Functioning cuts through the confusion, analyzing both the whole and its parts in comprehensive, practical detail for scholar and clinician alike. Background chapters examine influential models of EF, tour the brain geography of the executive system and pose salient developmental questions. A section on practical implications relates early deficits in executive functioning to ADD and other disorders in children and considers autism and later-life dementias from an EF standpoint. Further chapters weigh the merits of widely used instruments for assessing executive functioning and review interventions for its enhancement, with special emphasis on children and adolescents. Featured in the Handbook: The development of hot and cool executive function in childhood and adolescence. A review of the use of executive function tasks in externalizing and internalizing disorders. Executive functioning as a mediator of age-related cognitive decline in adults. Treatment integrity in interventions that target executive function. Supporting and strengthening working memory in the classroom to enhance executive functioning. The Handbook of Executive Functioning is an essential resource for researchers, scientist-practitioners and graduate students in clinical child, school and educational psychology; child and adolescent psychiatry; neurobiology; developmental psychology; rehabilitation medicine/therapy and social work.
Book Synopsis Progress in Autism Research by : Paul C. Carlisle
Download or read book Progress in Autism Research written by Paul C. Carlisle and published by Nova Publishers. This book was released on 2007 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the latest research in the battle against autism. According to numerous news reports, the increase in special needs children has reached epidemic proportions. Autism is a complex developmental disability that typically appears during the first three years of life. The result of a neurological disorder that affects the functioning of the brain, autism and its associated behaviours have been estimated to occur in as many as 2 to 6 in 1,000 individuals. Autism is four times more prevalent in boys than girls and knows no racial, ethnic, or social boundaries. Autism is a spectrum disorder. The symptoms and characteristics of autism can present themselves in a wide variety of combinations, from mild to severe. Although autism is defined by a certain set of behaviours, children and adults can exhibit any combination of the behaviours in any degree of severity. People with autism process and respond to information in unique ways. In some cases, aggressive and/or self-injurious behaviour may be present.

Book Synopsis Brain Connectivity in Autism by : Rajesh K. Kana
Download or read book Brain Connectivity in Autism written by Rajesh K. Kana and published by Frontiers E-books. This book was released on 2014-09-23 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain's ability to process information crucially relies on connectivity. Understanding how the brain processes complex information and how such abilities are disrupted in individuals with neuropsychological disorders will require an improved understanding of brain connectivity. Autism is an intriguingly complex neurodevelopmental disorder with multidimensional symptoms and cognitive characteristics. A biological origin for autism spectrum disorders (ASD) had been proposed even in the earliest published accounts (Kanner, 1943; Asperger, 1944). Despite decades of research, a focal neurobiological marker for autism has been elusive. Nevertheless, disruptions in interregional and functional and anatomical connectivity have been a hallmark of neural functioning in ASD. Theoretical accounts of connectivity perceive ASD as a cognitive and neurobiological disorder associated with altered functioning of integrative circuitry. Neuroimaging studies have reported disruptions in functional connectivity (synchronization of activated brain areas) during cognitive tasks and during task-free resting states. While these insights are valuable, they do not address the time-lagged causality and directionality of such correlations. Despite the general promise of the connectivity account of ASD, inconsistencies and methodological differences among studies call for more thorough investigations. A comprehensive neurological account of ASD should incorporate functional, effective, and anatomical connectivity measures and test the diagnostic utility of such measures. In addition, questions pertaining to how cognitive and behavioral intervention can target connection abnormalities in ASD should be addressed. This research topic of the Frontiers in Human Neuroscience addresses “Brain Connectivity in Autism” primarily from cognitive neuroscience and neuroimaging perspectives.

Book Synopsis Autism as an Executive Disorder by : James Russell
Download or read book Autism as an Executive Disorder written by James Russell and published by OUP Oxford. This book was released on 1997 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autism continues to fascinate researchers because it is both debilitating in its effects and complex in its nature and origins. The prevalent theory is that autism is primarily characterised by difficulties in understanding mental concepts, but the contributors to this book present new andcompelling arguments for an alternative theory. Their research points strongly to the idea that autism is primarily a disorder of "executive functions", those involved in the control of action and thought. As such, the book provides a new and controversial perspective on this importantquestion.

Book Synopsis The Oxford Handbook of Autism and Co-Occurring Psychiatric Conditions by : Susan W. White
Download or read book The Oxford Handbook of Autism and Co-Occurring Psychiatric Conditions written by Susan W. White and published by Oxford University Press, USA. This book was released on 2020-03-16 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-occurring psychiatric conditions are extremely common among people who have autism spectrum disorder (ASD). The Oxford Handbook of Autism and Co-Occurring Psychiatric Conditions presents a compilation of the latest research in this area, summarized by internationally renowned experts. Each chapter presents an overview of the problem or disorder including information on prevalence in ASD and in the general public and a synthesis of the research on etiology, diagnostic best practices, and evidence-based intervention approaches. Case studies bring these concepts to life, and each chapter concludes with suggestions for future research directions in order to further develop our scientific and clinical understanding of the particular comorbidity. Given the fact that comorbidity is often a chronic and pervasive concern, this Handbook takes a lifespan approach, with each chapter touching on developmental aspects of the targeted problem, from early childhood through adulthood. The concluding section of the Handbook is comprised of content on clinical considerations and research approaches, including chapters on medications commonly used to treat co-occurring conditions, strategies for managing crisis situations in this clinical population, and community partnerships within an implementation science framework.
Book Synopsis Electrophysiology of Inhibitory Control in the Context of Emotion Processing in Children with Autism Spectrum Disorder by : Justine Magnuson
Download or read book Electrophysiology of Inhibitory Control in the Context of Emotion Processing in Children with Autism Spectrum Disorder written by Justine Magnuson and published by . This book was released on 2018 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that affects 1 in 59 children. Despite this high prevalence of ASD, knowledge regarding the biological basis of its associated cognitive deficits, including emotion processing and inhibitory control abnormalities, remains scant. In this study, I aimed to identify altered neurophysiological responses underlying inhibitory control difficulties in the context of emotion processing in ASD, together with their associations with various domains of cognitive and social function, and age. This was accomplished by assessing electroencephalographic recordings during an emotional go/nogo task alongside various parent rating scales of behaviour. Event related potential N2 component amplitudes were reduced in children with ASD compared to typically developing (TD) children. Consistent with previous findings, increased age correlated with improved behavioural accuracy and reduced N2 amplitude in the TD group, indicating that as these children develop, their neural systems underlying inhibition become more efficient. However, these associations were not observed in the ASD group. Relations between various behavioural scores and N2 amplitude were also only significant in the TD group, revealing an association between increased N2 amplitudes and improved executive control abilities and decreased autism traits in these children. The newly discovered findings of differences in neural processing between children with ASD and TD children during an emotional inhibitory control task, alongside a lack of correlation between these neural responses, age and various behavioural scores in the ASD group, provide a potential neurophysiological indicator of atypical development of inhibitory control mechanisms in children with ASD.
Book Synopsis Autism Spectrum Disorders by : Andreas M. Grabrucker
Download or read book Autism Spectrum Disorders written by Andreas M. Grabrucker and published by . This book was released on 2021 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autism spectrum disorders are developmental disorders. Individuals with autism spectrum disorders develop differently. These differences are usually present in social interaction, communication, and sensory processing, and become visible through a wide variety of behavioral responses that differ from individuals without autism spectrum disorders. Despite significant research efforts, the exact causes of autism spectrum disorders remain poorly understood; however, researchers have gained extensive insights into possible pathomechanisms, even at the molecular level of cells. Many diagnostic criteria have been developed, adapted, and improved. The eight chapters in this book highlight the current state-of-the-art in many areas of autism spectrum disorders. Chapter 1 provides an overview of the epidemiology of autism spectrum disorders and the current knowledge of the underlying pathogenic mechanisms. Chapter 2 summarizes the diagnostic criteria and procedures and highlights present and upcoming therapeutic strategies. Chapter 3 reviews the adverse events and trauma in people with autism spectrum disorders. Chapters 4 and 5 focus on atypical sensory processing, and Chapter 6 discusses the genetic overlap of autism spectrum disorders with other neuropsychiatric disorders such as attention deficit hyperactivity disorder (ADHD), depression, and schizophrenia. Chapter 7 focuses on the contribution of abnormalities in mitochondria, and chapter 8 discusses gut-brain interactions and a potential role for microbiota in autism spectrum disorders. This book is aimed primarily at clinicians and scientists, but many areas will also be of interest to the layperson.

Book Synopsis Infant EEG and Event-Related Potentials by : Michelle de Haan
Download or read book Infant EEG and Event-Related Potentials written by Michelle de Haan and published by Psychology Press. This book was released on 2013-04-15 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infancy is a time of rapid growth, when brain plasticity is at a maximum. Event-related potentials (ERPs) are one of the few methods that can easily and safely be used to study this process, and have led to exciting discoveries about human brain functioning and the neural basis of cognition. Over recent years, there has been a massive rise in the level of interest in ERPs and this book considers the advantages which they offer to researchers and clinicians. In particular, it looks at the benefits of this form of neuroimaging as a non-invasive tool for detecting impairments in brain and cognitive development very early in life. The potential use of ERPs for clinical settings is also explored in detail. The contributions are all from eminent researchers in the field and represent the latest thought on the topic. Infant EEG and Event-Related Potentials explains the basics of event-related potentials for those less familiar with the procedures and terminology, as well as offering a valuable handbook of the latest theories and empirical findings for those working in the field. This will be a valuable source for those interested in developmental psychology and neuropsychology, and for clinicians interested in application of ERPs.
