Book Synopsis Executive Function(s): Conductor, Orchestra or Symphony? Towards a Trans-Disciplinary Unification of Theory and Practice Across Development, in Normal and Atypical Groups by : Lynne A. Barker
Download or read book Executive Function(s): Conductor, Orchestra or Symphony? Towards a Trans-Disciplinary Unification of Theory and Practice Across Development, in Normal and Atypical Groups written by Lynne A. Barker and published by Frontiers Media SA. This book was released on 2018-08-30 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several theories of executive function(s) that tend to share some theoretical overlap yet are also conceptually distinct, each bolstered by empirical data (Norman and Shallice, 1986; Shallice & Burgess, 1991; Stuss and Alexander, 2007; Burgess, Gilbert, & Dumentheil, 2007; Burgess & Shallice, 1996; Miyake et al., 2000). The notion that executive processes are supervisory, and most in demand in novel situations was an early conceptualization of executive function that has been adapted and refined over time (Norman & Shallice, 1986; Shallice, 2001; Burgess, Gilbert & Dumentheil, 2007). Presently there is general consensus that executive functions are multi-componential (Shallice, 2001), and are supervisory only in the sense that attention in one form or another is key to the co-ordination of other hierarchically organized ‘lower’ cognitive processes. Attention in this sense is defined as (i) independent but interrelated attentional control processes (Stuss & Alexander, 2007); (ii) automatic orientation towards stimuli in the environment or internally–driven thought (Burgess, Gilbert & Dumontheil, 2007); (iii) the automatically generated interface between tacit processes and strategic conscious thought (Barker, Andrade, Romanowski, Morton and Wasti, 2006; Morton and Barker, 2010); and (iv) distinct but interrelated executive processes that maintain, update and switch across different sources of information (Miyake et al., 2000). One problem is that executive dysfunction or dysexecutive syndrome (Baddeley & Wilson, 1988) after brain injury typically produces a constellation of deficits across social, cognate, emotional and motivational domains that rarely map neatly onto theoretical frameworks (Barker, Andrade & Romanowski, 2004). As a consequence there is debate that conceptual theories of executive function do not always correspond well to the clinical picture (Manchester, Priestley & Jackson, 2004). Several studies have reported cases of individuals with frontal lobe pathology and impaired daily functioning despite having little detectable impairment on traditional tests of executive function (Shallice & Burgess, 1991; Eslinger & Damasio, 1985; Barker, Andrade & Romanowski, 2004; Andrés & Van der Linden, 2002; Chevignard et al., 2000; Cripe, 1998; Fortin, Godbout & Braun, 2003). There is also some suggestion that weak ecological validity limits predictive and clinical utility of many traditional measures of executive function (Burgess et al, 2006; Lamberts, Evans & Spikman, 2010; Barker, Morton, Morrison, McGuire, 2011). Complete elimination of environmental confounds runs the risk of generating results that cannot be generalized beyond constrained circumstances of the test environment (Barker, Andrade & Romanowski, 2004). Several researchers have concluded that a new approach is needed that is mindful of the needs of the clinician yet also informed by the academic debate and progress within the discipline (McFarquhar & Barker, 2012; Burgess et al., 2006). Finally, translational issues also confound executive function research across different disciplines (psychiatry, cognitive science, and developmental psychology) and across typically developing and clinical populations (including Autism Spectrum Disorders, Head Injury and Schizophrenia – Blakemore & Choudhury, 2006; Taylor, Barker, Heavey & McHale, 2013). Consequently, there is a need for unification of executive function approaches across disciplines and populations and narrowing of the conceptual gap between theoretical positions, clinical symptoms and measurement.
Book Synopsis Cognitive Development and Individual Variability by : Anik De Ribaupierre
Download or read book Cognitive Development and Individual Variability written by Anik De Ribaupierre and published by MDPI. This book was released on 2019-07-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard approach to cognitive development most frequently consists of cross-sectional studies comparing different ages and groups while restricted to a single task. The necessity to focus on the individual in an idiographic perspective, rather than on the task or the variable, has been repeatedly emphasized, most recently in several very important papers by Nesselroade and Molenaar. Variability has also emerged as a crucial characteristic. Moreover, understanding the developmental construction of a given cognitive achievement is imperative to understanding cognitive functioning in adulthood. The general objective of this book is to focus on the individual by studying intraindividual and interindividual variability in various cognitive tasks, that is, intraindividual variability across items of a given task (“inconsistency”), across various cognitive tasks (“dispersion”), and/or across years (“intraindividual change”), and of course, on interindividual differences in intraindividual variability. This book presents empirical studies that have been conducted by research groups in Europe and in North America, prominent in the field of variability and development or methodology. The 26 authors/co-authors include senior authors such as Lautrey, Schmiedek, Dauvier, van der Maas, Ghisletta, Stawski, MacDonald, and de Ribaupierre.
Book Synopsis Executive Functions and the Frontal Lobes by : Vicki Anderson
Download or read book Executive Functions and the Frontal Lobes written by Vicki Anderson and published by Psychology Press. This book was released on 2010-10-18 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume has as its primary aim the examination of issues concerning executive function and frontal lobe development. While many texts have addressed these issues, this is the first to do so within a specifically developmental framework. This area of cognitive function has received increasing attention over the past decade, and it is now established that the frontal lobes, and associated executive functions, are critical for efficient functioning in daily life. It is also clear, and of particular relevance to this text, that these functions develop gradually through childhood, and then deteriorate during old age. These developmental trajectories, and the impact of any interruption to them, are the focus of this volume.

Book Synopsis Dysexecutive Syndromes by : Alfredo Ardila
Download or read book Dysexecutive Syndromes written by Alfredo Ardila and published by Springer Nature. This book was released on 2019-08-29 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of executive functioning has become central in understanding normal and abnormal cognitive processes. This timely volume analyzes the diverse conditions that can result in executive function disturbances, providing research about underlying causes, exploring the differences between developmental and acquired executive "dysfunctions," and providing approaches for the assessment of executive dysfunction both in children and in adults. In doing so, it addresses a gap in the literature in its analysis of executive function deficits and their link with psychopathology in psychiatric patients for the management of clinical symptoms and social adjustment. Among the specific topics examined: Theoretical approaches for the analysis of the diverse dysexecutive syndromes Common executive dysfunction syndromes found during childhood development: attention deficit hyperactivity disorder and autism spectrum disorders Consequences of executive function deficits in the use of information technology Executive dysfunction and personality disorders Common executive function tests, assessment issues in executive dysfunction, and cross-cultural and bilingual questions in assessment of executive dysfunction Dysexecutive Syndromes: Clinical and Experimental Perspectives expertly extends the analysis of executive functions and dysfunctions from a fundamental and clinical perspective. It is essential reading for clinical psychologists, neuropsychologists, neurologists, and psychiatrists, and graduate and post-graduate students in psychology, neurology, and the health neurosciences, as well as clinicians, counselors, and psychometricians working with neuropsychiatric assessment.

Book Synopsis The Cambridge Handbook of Cognitive Aging by : Ayanna K. Thomas
Download or read book The Cambridge Handbook of Cognitive Aging written by Ayanna K. Thomas and published by Cambridge University Press. This book was released on 2020-05-28 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of research have demonstrated that normal aging is accompanied by cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal, and decrements in older adult performance may be moderated by experience, genetics, and environmental factors. Cognitive aging research to date has also largely emphasized biological changes in the brain, with less evaluation of the range of external contributors to behavioral manifestations of age-related decrements in performance. This handbook provides a comprehensive overview of cutting-edge cognitive aging research through the lens of a life course perspective that takes into account both behavioral and neural changes. Focusing on the fundamental principles that characterize a life course approach - genetics, early life experiences, motivation, emotion, social contexts, and lifestyle interventions - this handbook is an essential resource for researchers in cognition, aging, and gerontology.

Book Synopsis Communication Problems in Autism by : Eric Schopler
Download or read book Communication Problems in Autism written by Eric Schopler and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North Carolina State Legislature's mandate to Division TEACCH has three major components. First, to provide the most up-to-date and cost effective services possible for families with autistic or similar language impaired children; second, to conduct research aimed toward the better under standing of such devastating disorders; and third, to provide training for the professionals needed to pursue these goals. One element in achieving these aims is to hold annual conferences on topics of special importance to the under standing and treatment of autism and similar disorders. In addition to training professionals and parents on the most recent de velopments in each conference topic, we are publishing a series, Current Issues in Autism, based on these conferences. These books are not, however, simply the published proceedings of the conference papers. Instead, some chapters are expanded conference presentations, whereas others come from national and in ternational experts whose work is beyond the scope of the conference, but es sential in our attempt at comprehensive coverage of the conference theme. These volumes are intended to provide the most current knowledge and profes sional practice available to us at the time.
Book Synopsis Monitoring Metabolic Status by : Institute of Medicine
Download or read book Monitoring Metabolic Status written by Institute of Medicine and published by National Academies Press. This book was released on 2004-08-29 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military's concerns about the individual combat service member's ability to avoid performance degradation, in conjunction with the need to maintain both mental and physical capabilities in highly stressful situations, have led to and interest in developing methods by which commanders can monitor the status of the combat service members in the field. This report examines appropriate biological markers, monitoring technologies currently available and in need of development, and appropriate algorithms to interpret the data obtained in order to provide information for command decisions relative to the physiological "readiness" of each combat service member. More specifically, this report also provides responses to questions posed by the military relative to monitoring the metabolic regulation during prolonged, exhaustive efforts, where nutrition/hydration and repair mechanisms may be mismatched to intakes and rest, or where specific metabolic derangements are present.

Book Synopsis Sensing the Environment: Regulation of Local and Global Homeostasis by the Skin's Neuroendocrine System by : Andrzej T. Slominski
Download or read book Sensing the Environment: Regulation of Local and Global Homeostasis by the Skin's Neuroendocrine System written by Andrzej T. Slominski and published by Springer Science & Business Media. This book was released on 2012-06-02 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The skin, the body’s largest organ, is strategically located at the interface with the external environment where it detects, integrates and responds to a diverse range of stressors, including solar radiation. It has already been established that the skin is an important peripheral neuroendocrine-immune organ that is closely networked with central regulatory systems. These capabilities contribute to the maintenance of peripheral homeostasis. Specifically, epidermal and dermal cells produce and respond to classical stress neurotransmitters, neuropeptides and hormones, production which is stimulated by ultraviolet radiation (UVR), biological factors (infectious and non-infectious) and other physical and chemical agents. Examples of local biologically active products are cytokines, biogenic amines (catecholamines, histamine, serotonin and N-acetyl-serotonin), melatonin, acetylocholine, neuropeptides including pituitary (proopiomelanocortin-derived ACTH, b-endorphin or MSH peptides, thyroid stimulating hormone) and hypothalamic (corticotropin-releasing factor and related urocortins, thyroid-releasing hormone) hormones, as well as enkephalins and dynorphins, thyroid hormones, steroids (glucocorticoids, mineralocorticoids, sex hormones, 7-δ steroids), secosteroids, opioids and endocannabinoids. The production of these molecules is hierarchical, organized along the algorithms of classical neuroendocrine axes such as the hypothalamic pituitary adrenal axis (HPA), hypothalamic-thyroid axis (HPT), serotoninergic, melatoninergic, catecholaminergic, cholinergic, steroid/secosteroidogenic, opioid and endocannabinoid systems. Disruptions of these axes or of communication between them may lead to skin and/or systemic diseases. These local neuroendocrine networks also serve to limit the effect of noxious environmental agents to preserve local and consequently global homeostasis. Moreover, the skin-derived factors/systems can also activate cutaneous nerve endings to alert the brain to changes in the epidermal or dermal environments, or alternatively to activate other coordinating centers by direct (spinal cord) neurotransmission without brain involvement. Furthermore, rapid and reciprocal communications between epidermal and dermal and adnexal compartments are also mediated by neurotransmission including antidromic modes of conduction. Lastly, skin cells and the skin as an organ coordinate and/or regulate not only peripheral but also global homeostasis.

Download or read book Population Health: Behavioral and Social Science Insights written by Robert M. Kaplan and published by Government Printing Office. This book was released on 2015-07-24 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to gain a better understanding of the multitude of factors that determine longer life and improved quality of life in the years a person is alive. While the emphasis is primarily on the social and behavioral determinants that have an effect on the health and well-being of individuals, this publication also addresses quality of life factors and determinants more broadly. Each chapter in this book considers an area of investigation and ends with suggestions for future research and implications of current research for policy and practice. The introductory chapter summarizes the state of Americans’ health and well-being in comparison to our international peers and presents background information concerning the limitations of current approaches to improving health and well-being. Following the introduction, there are 21 chapters that examine the effects of various behavioral risk factors on population health, identify trends in life expectancy and quality of life, and suggest avenues for research in the behavioral and social science arenas to address problems affecting the U.S. population and populations in other developed and developing countries around the world. Undergraduate and graduate students pursuing coursework in health statistics, health population demographics, behavioral and social science, and heatlh policy may be interested in this content. Additionally, policymakers, legislators, heatlh educators, and scientific organizations around the world may also have an interest in this resource.
