The advent of modern investigative techniques to explore brain function has led to major advances in understanding the neural organization and mechanisms associated with semantic memory. This book presents current theories by leading experts in the field on how the human nervous system stores and recalls memory of objects, actions, words and events. Chapters range from models of a specific domain or memory system (e.g., lexical-semantic, sensorimotor, emotion) to multiple modality accounts; from encompassing memory representations, to processing modules, to network structures, focusing on studies of both normal individuals and those with brain disease. Recent advances in neuro-exploratory techniques allow for investigation of semantic memory mechanisms noninvasively in both normal healthy individuals and patients with diffuse or focal brain damage. This has resulted in a significant increase in findings relevant to the localization and mechanistic function of brain regions engaged in semantic memory, leading to the neural models included here.
The area of concern to Dr. Wietske Noordman~Vonk has been variously seen as an aspect of long-term memory [F. I], secondary memory [F. 2], memory without record [F. 3], and semantic memory [F. 4J, the latter term being the one pre ferred by Dr. Noordman-Vonk herself. This proliferation of terminology is not an entirely trivial matter, for although the expressions clearly overlap in range, they do draw attention to different features of the phenomena under consideration. The work reported here is concerned with the form of representation and manipulation of our knowledge that, for example, a dog is an animal, or that mothers and daughters are parents and children. To put it more generally, the experiments attempt to elucidate the psychological processes involved in the~emantics of class-inclusion and, most importantly, to extend the explanatory principles there invoked to a new domain, that of kinship relations. Clearly, the connections between "ant" and "insect", or "flower" and "plant" have been known to us - as adults - for some considerable period of time; in the absence of brain injury or degeneration we are unlikely to "forget" that fathers and sons are kin of the same sex. We may therefor- pretheoretically - distinguish between retrieval of such knowledge and. re trieval of a rapidly fading sequence of random numbers that we are asked to recall after a single presentation. It is in this sense that the current work is concerned with long-term and not short-term memory.
A collection of leading models of how the human brain encodes for the memory of the items that surround us.
It is only relatively recently that it has been possible to study the neural processes that might underlie working memory, leading to a proliferation of research in this domain. This volume brings together leading researchers from around the world to summarise current knowledge of this field.
Humans have a unique ability to understand the beliefs, emotions, and intentions of others—a capacity often referred to as mentalizing. Much research in psychology and neuroscience has focused on delineating the mechanisms of mentalizing, and examining the role of mentalizing processes in other domains of cognitive and affective functioning. The purpose of the book is to provide a comprehensive overview of the current research on the mechanisms of mentalizing at the neural, algorithmic, and computational levels of analysis. The book includes contributions from prominent researchers in the field of social-cognitive and affective neuroscience, as well as from related disciplines (e.g., cognitive, social, developmental and clinical psychology, psychiatry, philosophy, primatology). The contributors review their latest research in order to compile an authoritative source of knowledge on the psychological and brain bases of the unique human capacity to think about the mental states of others. The intended audience is researchers and students in the fields of social-cognitive and affective neuroscience and related disciplines such as neuroeconomics, cognitive neuroscience, developmental neuroscience, social cognition, social psychology, developmental psychology, cognitive psychology, and affective science. Secondary audiences include researchers in decision science (economics, judgment and decision-making), philosophy of mind, and psychiatry.
How is information stored and retrieved from long-term memory? It is argued that any systematic attempt to answer this question should be based on a particular set of specific representational assumptions that have led to the development of a new memory theory -- the connectivity model. One of the crucial predictions of this model is that, in sharp contrast to traditional theories, the speed of processing information increases as the amount and complexity of integrated knowledge increases. In this volume, the predictions of the model are examined by analyzing the results of a variety of different experiments and by studying the outcome of the simulation program CONN1, which illustrates the representation of complex semantic structures. In the final chapter, the representational assumptions of the connectivity model are evaluated on the basis of neuroanatomical and physiological evidence -- suggesting that neuroscience provides valuable knowledge which should guide the development of memory theories.
