Enough has been learnt about the organic amnesia syndrome for research to be driven by theoretical ideas about the possible causes of the memory deficits underlying it. These theoretical ideas attempt to specify whether one or several distinct functional deficits cause the memory problems typically seen in the syndrome, what the precise nature of these deficits actually is, and what is the exact location of the lesions that cause them.; This special issue of "Memory" is devoted to articles that advance different accounts of some or all of the features of amnesia. It highlights that, although there is still no full agreement about the neuroanatomy of amnesia, whether it is a unitary condition, and the causes of and relationship between anterograde and retrograde amnesia, many theories converge in suggesting that damage to the hippocampus and its connections dirupts aspects of memory for complex associations that are ultimately represented in the neocortex.
Brain damage can cause memory to break down in a number of different ways, the analysis of which can illuminate how the intact brain mediates memory processes. After first considering the problems involved in assessing memory, this book provisionally advances a taxonomy of elementary memory disorders and, for each in turn, reviews both the specific processes that are disrupted and the lesions responsible for the disruption. These disorders include short-term memory deficits, deficits in previously well-established memory, memory decifits caused by frontal lobe lesions, the organic amnesias, the disorders of conditioning and skill acquisition. Particular attention is paid to the organic amnesias, about which we know the most, and to the contributions of animal models to our knowledge. Andrew Mayes argues that the memory deficits found in several neurological and psychiatric syndromes comprise co-occurring elementary memory disorders. Finally, he outlines the implications of his taxonomy for our understanding of normal memory. A wide audience of researchers and students will find Human Organic Memory Disorders a helpful guide to a complex problem area.
Originally published in 1982, this book brings together two areas of research previously studied in parallel, with little interaction (particularly in the US): normal memory processing and the amnesic syndrome. When trying to document the relationship between the two it became apparent that there was much crossover and duplication of effort in a number of areas: whether long-term memory and short-term memory truly represent independent storage systems, or are simply points on a continuum; trying to determine the primary locus of variables influencing the rate at which information is lost during retention; whether episodic memory and semantic memory represent two different storage systems, or are simply artifacts produced by different kinds of query to a single memory system and finally, whether visual and verbal memory are independent. It was written, following a meeting in 1979, by a small group of investigators, brought together to explore this commonality and to share data and theory, thus beginning the promise of a bright future of interdisciplinary interaction in memory research.
This new edition gives an up-to-date account of the causes, anatomical basis, and mechanisms of confabulations. It traces the history of the phenomenon of false memories, considers a range of clinical cases, and makes important recommendations for future study. It is essential for neurologists, psychiatrists, and cognitive neuroscientists.
"Neurobiology of Cognition and Behavior" is a cognitive neuroscience that maps cognitive/behavioral units with anatomical regions in the human brain. The brain-behavioral associations are based on functional neuroimaging combined with lesion studies. The findings will be used to explain differences in clinical syndromes with videos of patients included.
Memory complaints are a frequent feature of psychiatric disorder, even in the absence of organic disease. In this practical reference for the clinician, first published in 2000, German Berrios and John Hodges lead an international team of eminent psychiatrists, behavioural neurologists and clinical psychologists to focus on the psychiatric and organic aspects of memory disorders from the perspective of the multidisciplinary memory clinic. These disorders include organic syndromes such as the dementias, the amnesic syndrome and transient amnestic states, and also psychiatric aspects of memory disorders in the functional psychoses. Among the specific topics reviewed are the paramnesias, conditions such as déjà vu, flashbulb and flashback memories, and the problems of recovered, false and feigned memories. Throwing light on established conditions, and also introducing two new syndromes, this book makes a major contribution to the understanding and clinical management of memory disorders in psychiatry, neuropsychology and other disciplines.
David Groome with Nicola Brace, Graham Edgar, Helen Edgar, Michael Eysenck, Tom Manly, Hayley Ness, Graham Pike, Sophie Scott, and Elizabeth Styles. An Introduction to Cognitive Psychology: Processes and Disorders is a comprehensive introductory textbook for undergraduate students. The third edition of this well-established text has been completely revised and updated to cover all the key areas of cognition, including perception, attention, memory, thinking and language. Uniquely, alongside chapters on normal cognitive function, there are chapters on related clinical disorders (agnosia, amnesia, thought disorder and aphasia) which help to provide a thorough insight into the nature of cognition. Key features: Completely revised and updated throughout to provide a comprehensive overview of current thinking in the field Accessibly written and including new authors, including Sophie Scott, Tom Manly, Hayley Ness, and Elizabeth Styles, all established experts in their field A new chapter on Emotion and Cognition, written by Michael Eysenck, the leading authority in the field Greater coverage of neuropsychological disorders, with additional material from the latest brain imaging research that has completely revolutionized neuropsychology Specially designed textbook features, chapter summaries, further reading, and a glossary of key terms A companion website featuring an extensive range of online resources for both teachers and students. Written to cover all levels of ability using helpful figures and illustrations, An Introduction to Cognitive Psychology has sufficient depth to appeal to the most able students while the clear and accessible text, written by experienced teachers, will help students who find the material difficult. It will appeal to any student on an undergraduate psychology degree course, as well as to medical students and those studying in related clinical professions such as nursing.
Originally published in 1986, this book was written for undergraduates who had completed an introductory course in psychology, and aimed to acquaint the student with the core of recent experimental findings and theoretical ideas concerning human memory. Each chapter deals with a specific area of memory research but care is taken to build on what has been covered in preceding chapters, so providing an integrated treatment of the subject. Thus, the book can comfortably be read from cover to cover, or selected issues can be referred to in isolation. Important features of the book include discussion of fundamental issues about the nature of the scientific process, the role of models and theories in it, and the historical development of models of human memory. Also, the treatment of ‘Forgetting’ includes chapters on motivational aspects (psychopathological forgetting, post-hypnotic amnesia, and directed forgetting), and organic amnesia.
