Available in PDF, EPUB and Kindle. Book excerpt: The aim of this thesis is to investigate competing explanations of the processes underlying associative recognition. Like recognition memory for individual items, associative recognition is currently understood through two different classes of model. The first is the single-process model class which holds that associative recognition decisions are based on a continuum of associative memory strength. The second is the dual-process model class, which holds that associative recognition decisions are based on two sources of information, called familiarity and recollection. Familiarity is conceptualised as a fast-acting, context-free 'feeling of knowing', while recollection is said to be a slower, more conscious process allowing for the recall of detail and context. Familiarity may play a role in associative recognition through a mechanism called unitisation, whereby two distinct stimuli are bound into a single individual memory trace. State-trace analysis is a method to determine the number of latent variables or processes that contribute to performance on a set of tasks, under mild assumptions. A critical diagnostic feature is the dimensionality of the state-trace plot - a plot of performance on one dependent variable against the other. If associative recognition depends on a single latent variable then manipulation of experimental factors affecting memory should result in a unidimensional state-trace plot. If associative recognition depends on two or more latent variables which are differentially affected by the experimental factors then a bidimensional state-trace will result. State-trace analysis therefore provides a method of discriminating a class of single-process models from a class of dual-process models. State-trace analysis was applied to associative recognition in four experiments. Each experiment utilised two independent variables that previous research had suggested could differentially affect familiarity and recollection. Experiment 1 investigated associative recognition of word pairs by manipulating attention and study presentation frequency. Experiments 2 investigated associative recognition of word pairs under conditions designed to encourage unitisation by pairing an encoding-based unitisation manipulation with a working memory load manipulation. Experiment 3 manipulated the same unitisation instructions as well as varying study time. Experiment 4 examined the effect of unitisation using pairs of faces and manipulated visual similarity and study time. State-trace analysis of the four experiments consistently revealed unidimensional state-trace plots. Using a recently developed monotonic regression statistical test, unidimensionality could not be rejected at either aggregate or individual participant level. Therefore, no evidence was found for the differential activation of familiarity and recollection in associative recognition. The results of this thesis are therefore consistent with a single-process account of associative recognition. These results also pose a challenge to dual-process models to identify alternate experimental manipulations that reveal the involvement of different component processes such as recollection and unitized familiarity.

Available in PDF, EPUB and Kindle. Book excerpt: An increase in average life expectancy has given rise to a number of pressing health challenges for the 21st century. Age-related memory loss, whether due to a neurodegenerative condition such as Alzheimer’s disease, or as a product of the normal process of aging, is perhaps the most significant of the health problems of old age presently confronting our society. The Preservation of Memory explores non-invasive, empirically sound strategies that can be implemented to ensure long-lasting and effective retention of information. The chapters in this volume describe and evaluate both well-established and novel methods for improving and strengthening memory, for people with and without dementia. They also look at ways in which effective detection and care can be implemented, and describe empirical findings that can be translated into everyday practice. The contributors take a multidisciplinary approach, motivated by the desire to look beyond and across boundaries to find new areas of knowledge and new opportunities. The Preservation of Memory will be useful reading for students and researchers focusing upon memory, aging and dementia, and also for mental health practitioners, social workers, and carers of persons living with dementia or other memory impairments.
Download or read book Associative Memory Cells Basic Units of Memory Trace written by Jin-Hui Wang and published by Springer Nature. This book was released on 2019-09-10 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on associative memory cells and their working principles, which can be applied to associative memories and memory-relevant cognitions. Providing comprehensive diagrams, it presents the author's personal perspectives on pathology and therapeutic strategies for memory deficits in patients suffering from neurological diseases and psychiatric disorders. Associative learning is a common approach to acquire multiple associated signals, including knowledge, experiences and skills from natural environments or social interaction. The identification of the cellular and molecular mechanisms underlying associative memory is important in furthering our understanding of the principles of memory formation and memory-relevant behaviors as well as in developing therapeutic strategies that enhance memory capacity in healthy individuals and improve memory deficit in patients suffering from neurological disease and psychiatric disorders. Although a series of hypotheses about neural substrates for associative memory has been proposed, numerous questions still need to be addressed, especially the basic units and their working principle in engrams and circuits specific for various memory patterns. This book summarizes the developments concerning associative memory cells reported in current and past literature, providing a valuable overview of the field for neuroscientists, psychologists and students.

Download or read book Sources of Interference in Item and Associative Recognition Memory written by Adam F. Osth and published by . This book was released on 2014 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: A powerful theoretical framework for exploring recognition memory is the global matching framework, in which a cue's memory strength reflects the similarity of the retrieval cues being matched against all of the contents of memory simultaneously. Contributions at retrieval can be categorized as matches and mismatches to the item and context cues, including the self match (match on item and context), item noise (match on context, mismatch on item), context noise (match on item, mismatch on context), and background noise (mismatch on item and context). I present a model that directly parameterizes the matches and mismatches to the item and context cues, which enables estimation of the magnitude of each interference contribution (item noise, context noise, and background noise). The model was fit within a hierarchical Bayesian framework to ten recognition memory datasets that employ manipulations of strength, list length, list strength, word frequency, study-test delay, and stimulus class in item and associative recognition. Estimates of the model parameters revealed at most a small contribution of item noise that varies by stimulus class, with virtually no item noise for single words and scenes. Despite the unpopularity of background noise in recognition memory models, background noise estimates dominated at retrieval across nearly all stimulus classes with the exception of high frequency words, which exhibited equivalent levels of context noise and background noise. These parameter estimates suggest that the majority of interference in recognition memory stems from experiences acquired prior to the learning episode.
Download or read book Associative Illusions of Memory written by David Gallo and published by Psychology Press. This book was released on 2013-05-13 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last decade has seen a flurry of experimental research into the neurocognitive underpinnings of illusory memories. Using simple materials and tests (e.g., recalling words or pictures), methods such as the famed Deese-Roediger-McDermott (DRM) task have attracted considerable attention. These tasks elicit false memories of nonstudied events that are vivid, long lasting, and difficult to consciously avoid. Additional research shows that these memory illusions are fundamentally related to more complex memory distortions. As a result, this rapidly expanding literature has generated a great deal of excitement - and even some controversy - in contemporary psychology. Associative Illusions of Memory provides an ambitious overview of this research area. Starting with the historical roots and major theoretical trends, this book exhaustively reviews the most recent studies by cognitive psychologists, neuropsychologists, and cognitive neuroscientists. The strengths and limits of various experimental techniques are outlined, and the large body of existing data is meaningfully distilled into a few core theoretical concepts. This book highlights the malleability of memory, as well as the strategies and situations that can help us avoid false memories. Throughout the review, it is argued that these basic memory illusions contribute to a deeper understanding of how human memory works.

Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."
Download or read book Scientific Approaches to Consciousness written by Jonathan D. Cohen and published by Psychology Press. This book was released on 2014-04-04 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many ways to approach the understanding of consciousness. Questions about these ways have occupied philosophers and metaphysicians for centuries. During the early growth of cognitive science the problem of consciousness remained taboo, but an increasing number of studies have either implicitly or explicitly begun to bear on its nature. These have been inspired by a number of different different original questions, and focus on a variety of different empirical phenomena. Thus, studies of implicit memory, subliminal processing, strategic versus automatic processing, allocation of attention, and differences between information processes in the awake versus dreaming state all share a common assumption of a particular quality or state -- awakeness, awareness, alertness, namely consciousness -- that somehow can be distinguished from another type of state or states in which the subject is not aware of the information being processed. What distinguishes the cognitive psychological and cognitive neuroscience approach to the question of consciousness from that of philosophy and metaphysics is scientific methodology: a set of tools that permit the empirical study of a phenomenon in an objective and reproducible way. Recent developments in both the empirical and theoretical methodologies of these fields have made it possible to begin to study the phenomenon associated with -- if not directly underlying -- consciousness in a scientific fashion. This volume tries to resolve the difficulties associated with the scientific investigation of consciousness. The intent is to explore the extent to which consciousness can be the target of direct scientific inquiry, to get on the table some of the relevant work, and consider the degree to which this research can help inform our understanding of consciousness. It brings together a group of cognitive and neuroscientists to share relevant recent research in the fields of cognitive science and neuroscience and to determine whether any new strategies for the scientific pursuit of this question can be developed. A long-term goal is the development of a unified understanding of consciousness, scientific as well as philosophical perspectives. This volume takes the first step toward building the necessary local bridges.
Download or read book Foundations of Human Memory written by Michael Jacob Kahana and published by Oxford University Press. This book was released on 2014-05-01 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Human Memory provides an introduction to the scientific study of human memory with an emphasis on both the major theories of memory and the laboratory studies that have been used to test those theories and inspire their further development. Written with the undergraduate student in mind, the text assumes no specific background in the subject, but a general familiarity with scientific method and quantitative approaches to the treatment of data. Foundations of human memory is organized around the major empirical paradigms used to study memory in the laboratory and the theories used to explain data obtained using those paradigms. The text begins with a focus on memory for individual items, building up to memory for associations between items, and finally to memory for entire sequences of items and the problem of memory search. Several major theories of memory are considered in detail, including strength theory, summed-similarity theory, neural network based theories, retrieved-context theory, and theories based on the division of memory into separate short-term and long-term storage systems. The text emphasizes basic research over applied problems, but brings in real-world examples and neuroscientific evidence as appropriate.
Download or read book Eyeblink Conditioning in Psychiatric Conditions State of the Field and Future Directions written by Tracy L. Greer and published by Frontiers Media SA. This book was released on 2017-09-22 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eyeblink classical conditioning (EBC) is a model paradigm for associative (also termed Pavlovian) learning, one of the simplest and best understood forms of learning and memory. Because EBC paradigms are readily adapted across species, the neural substrates of EBC have been well characterized, and include but are not limited to the cerebellum and anterior interpositus nucleus, the hippocampus, and prefrontal cortices. The ability to collect EBC data across many different species (i.e. including but not limited to humans) also has the distinct advantage of facilitating translational research, and therefore may be of particular benefit to elucidate mechanistic changes associated with a wide variety of psychiatric disorders. In fact, EBC paradigms have been employed to assess individuals with a wide range of neurological deficits (including Korsakoff’s amnesia, Alzheimer's disease as well as normal aging, dyslexia, inflammatory tremor, dystonia, and multiple sclerosis) and psychiatric disorders (including major depressive disorder, anxiety disorders, schizophrenia, autism, and alcohol use/addiction disorders). Individuals with these disorders exhibit differential impairments across different EBC task types (e.g., delay vs. trace EBC), with some showing impairment in one but not the other task and some showing impairments in both; across learning stage (e.g., acquisition, discrimination, or extinction), and across response variables (e.g., magnitude and timing of the conditioned eyeblink motor response, modality of the conditioned stimulus). Evaluating specific individual differences in the context of variable brain pathology should aid characterization and refinement of our understanding of complex neuropsychiatric disorders. The field of psychiatry has seen a transition from more traditional use of symptom clusters to define psychiatric disorders with subsequent examination of associated behaviors and traits, to the use of physiological and behavioral indicators to characterize individuals with respect to various psychological domains [in line with the National Institute of Mental Health Research Domain Criteria (RDoC) initiative]. This approach employs a neuroscience-based framework to assess the pathophysiology of chronic mental illnesses. Behavioral and cognitive processes are critical domains of interest in evaluating potential maladaptive patterns that may be indicative of specific psychopathologies. Furthermore, the rapid development of technological advances that allow for more detailed examination (e.g., EEG, MEG, MRI, fMRI, infrared imaging) and manipulation (e.g. transcranial magnetic and direct current stimulation) of brain functions should enhance our ability to better characterize EBC performance and its utility in characterizing aspects of particular neuropathologies. Substantial research evidence exists for the value of EBC paradigms to inform our understanding of the pathophysiologies underlying a wide variety of neurological and psychiatric disorders. Despite these findings, this readily implemented classic cognitive-behavioral paradigm is relatively underutilized in clinical settings. This e-book highlights recent convergence of clinical and research efforts in this area and aims to promote a resurgent interest in eyeblink classical conditioning, and to emphasize the potential for future translational and diagnostic applications of EBC in combination with other techniques to strengthen our understanding of alterations in brain function manifested in behaviors characteristic of specific psychopathologies.

Book excerpt: Models of Human Memory provides an overview of the state of knowledge on human memory models. The book begins with an introductory chapter on the basic stages of the memory system and the historical roots of memory models. The remaining chapters are organized into five parts. Part I on memory systems covers topics such as a system for perception and memory; multi-trace strength theory of memory; and a model for postperceptual verbal memory that postulates a single memory store, with multiple copies, called replicas, created in memory by rehearsal processes. Part II presents studies phoneme storage and word recognition. Part III on memory for associations examines the storage-retrieval theory for the memorizing processes and presents simple model of short-term memory (STM) for paired associates. Part IV on storage and retrieval mechanisms deals with mechanisms of repetition and rehearsal in short-term memory; models of recall and recognition; and memory search models. Part V presents a theory of human long-term associative memory; and examines conceptual and methodological interactions between information-processing investigations of cognitive activity and attempts to build models of memory.
