Download or read book The Neuropsychopathology of Schizophrenia written by Ming Li and published by Springer. This book was released on 2016-05-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the first major theoretical reviews of schizophrenia since the publication of the 5th edition of the APA’s Diagnostic and Statistical Manual, the DSM-5, this volume is a landmark in the history of schizophrenia research. It assembles recent groundbreaking developments in research on schizophrenia and reaffirms its central place in the mental health research agenda. Significantly, this volume reflects the paradigmatic shift in schizophrenia research applied in parallel to new approaches in psychiatric diagnosis. New models and findings from across disciplines in recent years reflect a new and greater understanding of the workings of the brain, which, in turn, helps develop our knowledge of the neuro and psychological processes in schizophrenia. Consequently, this volume illustrates a historical convergence of psychology, psychopathology and the neurosciences in schizophrenia. World-renowned leaders of the schizophrenia research community in fields such as neuroscience, p sychiatry, neuropsychology, and clinical psychology offer clear suggestions for further advances in psychological and medical interventions, assessment, prevention strategies, and research. And in keeping with other titles in the Nebraska Symposium on Motivation series, these papers are noteworthy for their depth of detail, scientific rigor, and clinical relevance. Included among the topics: Cognitive organization as a dimension of individual differences and psychopathology. Neurodevelopmental genomic strategies in the study of the psychosis spectrum. Multimodal brain and behavior indices of psychosis risk. The NIMH Research Domain Criteria Project: new approaches to classifying psychotic spectrum disorders. The Neuropsychopathology of Schizophrenia is one of the most forward-thinking and engaging treatments of the field in recent years, and is an i ndispensable text for all researchers, academics, and clinicians who treat or study mental illness, especially psychiatrists, psychologists, mental health practitioners, and neuroscientists specializing in schizophrenia.
Download or read book The Oxford Handbook of Perceptual Organization written by Johan Wagemans and published by OUP Oxford. This book was released on 2015-08-21 with total page 1121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perceptual organization comprises a wide range of processes such as perceptual grouping, figure-ground organization, filling-in, completion, perceptual switching, etc. Such processes are most notable in the context of shape perception but they also play a role in texture perception, lightness perception, color perception, motion perception, depth perception, etc. Perceptual organization deals with a variety of perceptual phenomena of central interest, studied from many different perspectives, including psychophysics, experimental psychology, neuropsychology, neuroimaging, neurophysiology, and computational modeling. Given its central importance in phenomenal experience, perceptual organization has also figured prominently in classic Gestalt writings on the topic, touching upon deep philosophical issues regarding mind-brain relationships and consciousness. In addition, it attracts a great deal of interest from people working in applied areas like visual art, design, architecture, music, and so forth. The Oxford Handbook of Perceptual Organization provides a broad and extensive review of the current literature, written in an accessible form for scholars and students. With chapter written by leading researchers in the field, this is the state-of-the-art reference work on this topic, and will be so for many years to come.

Available in PDF, EPUB and Kindle. Book excerpt: Individual differences in perception are widespread. Considering inter-individual variability, synesthetes experience stable additional sensations; schizophrenia patients suffer perceptual deficits in, eg, perceptual organization (alongside hallucinations and delusions). Is there a unifying principle explaining inter-individual variability in perception? There is good reason to believe perceptual experience results from inferential processes whereby sensory evidence is weighted by prior knowledge about the world. Perceptual variability may result from different precision weighting of sensory evidence and prior knowledge. We tested this hypothesis by comparing visibility thresholds in a perceptual hysteresis task across medicated schizophrenia patients (N = 20), synesthetes (N = 20), and controls (N = 26). Participants rated the subjective visibility of stimuli embedded in noise while we parametrically manipulated the availability of sensory evidence. Additionally, precise long-term priors in synesthetes were leveraged by presenting either synesthesia-inducing or neutral stimuli. Schizophrenia patients showed increased visibility thresholds, consistent with overreliance on sensory evidence. In contrast, synesthetes exhibited lowered thresholds exclusively for synesthesia-inducing stimuli suggesting high-precision long-term priors. Additionally, in both synesthetes and schizophrenia patients explicit, short-term priors--introduced during the hysteresis experiment--lowered thresholds but did not normalize perception. Our results imply that perceptual variability might result from differences in the precision afforded to prior beliefs and sensory evidence, respectively.

Download or read book Perceptual Organization written by Michael Kubovy and published by Routledge. This book was released on 2017-03-31 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1981, perceptual organization had been synonymous with Gestalt psychology, and Gestalt psychology had fallen into disrepute. In the heyday of Behaviorism, the few cognitive psychologists of the time pursued Gestalt phenomena. But in 1981, Cognitive Psychology was married to Information Processing. (Some would say that it was a marriage of convenience.) After the wedding, Cognitive Psychology had come to look like a theoretically wrinkled Behaviorism; very few of the mainstream topics of Cognitive Psychology made explicit contact with Gestalt phenomena. In the background, Cognition's first love – Gestalt – was pining to regain favor. The cognitive psychologists' desire for a phenomenological and intellectual interaction with Gestalt psychology did not manifest itself in their publications, but it did surface often enough at the Psychonomic Society meeting in 1976 for them to remark upon it in one of their conversations. This book, then, is the product of the editors’ curiosity about the status of ideas at the time, first proposed by Gestalt psychologists. For two days in November 1977, they held an exhilarating symposium that was attended by some 20 people, not all of whom are represented in this volume. At the end of our symposium it was agreed that they would try, in contributions to this volume, to convey the speculative and metatheoretical ground of their research in addition to the solid data and carefully wrought theories that are the figure of their research.
Download or read book Identifying SNP Correlates of a Schizophrenia Subtype Characterized by Poor Premorbid Functioning and Perceptual Organization Deficits written by Jamie M. Joseph and published by . This book was released on 2013 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schizophrenia has been defined as a neurodevelopmental disorder (Weinberger, 1987; Lewis & Levitt, 2002; Javitt & Coyle, 2004). The etiology of schizophrenia is thought to be comprised of a combination of genetic and environmental components. Although the estimated heritability of schizophrenia is 80% (Sullivan et al., 2003); well-known (e.g. psychosocial stressors) and unknown environmental factors have a significant role in the development of this disorder. These factors subsequently lead to epigenetic and neurochemical changes affecting brain structure and function; thus also characterizing schizophrenia as a neural circuitry disorder (Friston & Firth, 1995; Benes, 2000; Lisman et al., 2008). Visual perceptual organization and premorbid social-sexual functioning impairments are significant cognitive and social deficit traits that are found in many individuals with schizophrenia, and that are strongly correlated with each other. However, the relationship between these phenotypes and the genetic etiology of schizophrenia is not known. Furthermore, clarification of this issue is complicated by heterogeneity of perceptual and social history functioning in the disorder. Therefore, the aim of this study was to reduce heterogeneity compared to past studies by determining association of this combined phenotype to single nucleotide polymorphisms (SNPs) in genes associated with glutamatergic and GABAergic neurotransmitter systems; the primary hypothesized neurocircuitry of visual perceptual organization in schizophrenia. A combination of clinical assessments, a battery of visual perceptual organization tasks and saliva samples were ascertained in order to determine links between selected phenotypes and genotypes. The observed relationships among perceptual, clinical, demographic variables are consistent with past findings suggesting a possible patient subtype with poor premorbid social sexual functioning, significant disorganized symptoms, and abnormal visual perceptual functioning. While the contribution of specific SNPs to these phenotypes has not been definitively clarified, the psychosocial developmental and perceptual organization factors analyzed are suggested to interact in schizophrenia spectrum populations and thought to be related to the genetic liability of schizophrenia. Overall, the study data suggest that further study of well-defined phenotypes and potentially associated genetic variants may be useful for future studies in schizophrenia spectrum populations that aim to develop personalized treatments.
Download or read book Schizophrenia written by Arnold H. Buss and published by Transaction Publishers. This book was released on 2017 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven controversial approaches to schizophrenia, each assuming a distinctive model, biological, psychological, or social, are presented by their leading exponents. Arnold and Edith Buss deal with such fundamental issues as: What is the nature of schizophrenia? What general approach does each theory represent? What does each theory assume, what evidence does it require for proof, and what follows if the theory is correct? While the various approaches covered here have many differences and few similarities, they are not all mutually contradictory, and several may be combined into a larger synthesis. From a biological point of view, schizophrenia is a disease like any other, originating in heredity, tissue malformation, and physiological abnormality. The biological approach is represented here by a theory focusing on genetic and neurological aspects. The psychological approach treats schizophrenia as a failure of adjustment. Within this framework there is considerable disagreement. One theory emphasizes the cognitive problems of perceiving, thinking, and problem-solving; another centers on motivational disturbance, with its attendant problems of anxiety and withdrawal; and two theories focus on regressive behavior. Schizophrenia provides a stimulating basis for discussion by presenting the etiology of schizophrenia in terms of the most significant contemporary approaches. The juxtaposition of these viewpoints enables the professor to maximize students' interest as well as their insight into the complexity of contradictory evidence and opinions. Arnold H. Buss is professor of psychology at the University of Texas. He has taught at the Universities of Iowa and Pittsburgh and Rutgers University. His research publications include studies of anxiety, aggression, pain tolerance, stimulus generalization, and concept formation. He is author of ten books including The Psychology of Aggression, Psychopathology, and Personality: Evolutionary Heritage and Human Distinctiveness. Edith H. Buss was a research associate at the University of Texas and served in the same capacity at Carter Hospital, the University of Pittsburgh, and Rutgers University. She holds a master's degree in education from the University of Pittsburgh. She has conducted research with both normal and schizophrenic subjects.
