Book excerpt: The present series of experiments examined how aging and divided attention influence memory for item and associative information in a variety of contexts. Previous research has suggested that one reason for older adults' poorer episodic memory is an impairment in processing and retaining associative information. To examine this, older adults, younger adults, and younger adults under various divided attention conditions studied unrelated word pairs for a later recognition memory test of both single words and different combinations of word pairs (Experiments 1-3). Both older and younger divided attention adults performed less well than the full attention group, with the deficit in associative information being greater than the deficit in item information. In addition, a differentially greater associative impairment was found for the older adults, as shown by their heightened tendency to make false alarm responses to re-paired (conjunction) distracters. These findings are interpreted in a dual-process model of recognition memory, in which older adults rely more on familiarity rather than recollection when processing associative information. The ability to remember other types of associative information was further examined by using cued recall tests of associative memory that varied in terms of the degree of specificity. In these experiments (Experiments 4-6), participants studied items that were paired with either related or unrelated units of information, as well as specific numerical information (either quantity or price information). Although older adults had the greatest difficulty remembering specific arbitrary associations, this impairment was reduced when associations were made meaningful (as a result of expertise) or contained a certain degree of schematic support. These results are discussed in terms of how prior knowledge and evaluative processing can influence associative memory, and suggest that a framework of associative memory that emphasizes different levels of associative specificity is necessary to interpret how older adults access associative information. The overall pattern of results imply that observations of age-related differences in memory for associative information depend on differences in available attentional resources, grain size (degree of precision) analyses at both encoding and retrieval, schematic support, and the meaningfulness and specificity of the association., The purpose of the present research was to test the notion that divided attention interferes with the processing of associative information, and that as a result, memory performance for items as well as the relations among these items is impaired relative to full attention situations. Experiment 1 demonstrated that participants under divided attention are more likely to report recombined word pairs as previously seen word pairs, compared to participants under conditions of full attention. Experiment 2 revealed that the processing of contextual information is impaired under divided attention. The idea that reduced elaboration and reduced use of associative information mediates poor memory performance under conditions of divided attention was examined in Experiment 3. The series of experiments suggests that although the processing of associative information is disrupted under conditions of divided attention, other mechanisms also contribute to impair memory performance when attentional resources are reduced.

Download or read book Memory and Aging written by Moshe Naveh-Benjamin and published by Psychology Press. This book was released on 2012-05-04 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current demographical patterns predict an aging worldwide population. It is projected that by 2050, more than 20% of the US population and 40% of the Japanese population will be older than 65. A dramatic increase in research on memory and aging has emerged to understand the age-related changes in memory since the ability to learn new information and retrieve previously learned information is essential for successful aging, and allows older adults to adapt to changes in their environment, self-concept, and social roles. This volume represents the latest psychological research on different aspects of age-related changes in memory. Written by a group of leading international researchers, its chapters cover a broad array of issues concerning the changes that occur in memory as people grow older, including the mechanisms and processes underlying these age-related memory changes, how these changes interact with social and cultural environments, and potential programs intended to increase memory performance in old age. Similarly, the chapters draw upon diverse methodological approaches, including cross-cultural extreme group experimental designs, longitudinal designs assessing intra-participant change, and computational approaches and neuroimaging assessment. Together, they provide converging evidence for stability and change in memory as people grow older, for the underlying causes of these patterns, as well as for the heterogeneity in older adults’ performance. Memory and Aging is essential reading for researchers in memory, cognitive aging, and gerontology.
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 316 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.

Download or read book A Modern Approach to Regression with R written by Simon Sheather and published by Springer Science & Business Media. This book was released on 2009-02-27 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on tools and techniques for building regression models using real-world data and assessing their validity. A key theme throughout the book is that it makes sense to base inferences or conclusions only on valid models. Plots are shown to be an important tool for both building regression models and assessing their validity. We shall see that deciding what to plot and how each plot should be interpreted will be a major challenge. In order to overcome this challenge we shall need to understand the mathematical properties of the fitted regression models and associated diagnostic procedures. As such this will be an area of focus throughout the book. In particular, we shall carefully study the properties of resi- als in order to understand when patterns in residual plots provide direct information about model misspecification and when they do not. The regression output and plots that appear throughout the book have been gen- ated using R. The output from R that appears in this book has been edited in minor ways. On the book web site you will find the R code used in each example in the text.
Download or read book The Science of False Memory written by C. J. Brainerd and published by Oxford University Press. This book was released on 2005-05-05 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Findings from research on false memory have major implications for a number of fields central to human welfare, such as medicine and law. Although many important conclusions have been reached after a decade or so of intensive research, the majority of them are not well known outside the immediate field. To make this research accessible to a much wider audience, The Science of False Memory has been written to require little or no background knowledge of the theory and techniques used in memory research. Brainerd and Reyna introduce the volume by considering the progenitors to the modern science of false memory, and noting the remarkable degree to which core themes of contemporary research were anticipated by historical figure such as Binet, Piaget, and Bartlett. They continue with an account of the varied methods that have been used to study false memory both inside and outside of the laboratory. The first part of the volume focuses on the basic science of false memory, revolving around three topics: old and new theoretical ideas that have been used to explain false memory and make predictions about it; research findings and predictions about false memory in normal adults; and research findings and predictions about age-related changes in false memory between early childhood and adulthood. Throughout Part I, Brainerd and Reyna emphasize how current opponent-processes conceptions of false memory act as a unifying influence by integrating predictions and data across disparate forms of false memory. The second part focuses on the applied science of false memory, revolving around four topics: the falsifiability of witnesses and suspects memories of crimes, including false confessions by suspects; the falsifiability of eyewitness identifications of suspects; false-memory reports in investigative interviews of child victims and witnesses, particularly in connection with sexual-abuse crimes; false memory in psychotherapy, including recovered memories of childhood abuse, multiple-personality disorders, and recovered memories of previous lives. Although Part II is concerned with applied research, Brainerd and Reyna continue to emphasize the unifying influence of opponent-processes conceptions of false memory. The third part focuses on emerging trends, revolving around three expanding areas of false-memory research: mathematical models, aging effects, and cognitive neuroscience. False Memory will be an invaluable resource for professional researchers, practitioners, and students in the many fields for which false-memory research has implications, including child-protective services, clinical psychology, law, criminal justice, elementary and secondary education, general medicine, journalism, and psychiatry.

Download or read book Attentional Capture written by Bradley S. Gibson and published by . This book was released on 2008 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The notion that certain mental or physical events can capture attention has been one of the most enduring topics in the study of attention owing to the importance of understanding how goal-directed and stimulus-driven processes interact in perception and cognition. Despite the clear theoretical and applied importance of attentional capture, a broad survey of this field suggests that the term "capture" means different things to different people. In some cases, it refers to covert shifts of spatial attention, in others involuntary saccades, and in still others general disruption of processing by irrelevant stimuli. The properties that elicit "capture" can also range from abruptly onset or moving lights, to discontinuities in textures, to unexpected tones, to emotionally valenced words or pictures, to directional signs and symbols. Attentional capture has been explored in both the spatial and temporal domains as well as the visual and auditory modalities. There are also a number of different theoretical perspectives on the mechanisms underlying "capture" (both functional and neurophysiological) and the level of cognitive control over capture. This special issue provides a sampling of the diversity of approaches, domains, and theoretical perspectives that currently exist in the study of attentional capture. Together, these contributions should help evaluate the degree to which attentional capture represents a unitary construct that reflects fundamental theoretical principles and mechanisms of the mind.
Download or read book Memory Attention and Aging written by Fergus I. M. Craik and published by Routledge. This book was released on 2016-10-26 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Memory, Attention, and Aging is a collection of some of the most influential journal articles previously published by Fergus Craik and his collaborators, with new introductory material unifying the research of this noted cognitive psychologist. The reprinted articles are grouped into six sections reflecting Craik’s various research interests across his career. The first section on short-term memory focuses on research concerns Craik uncovered in the 1970s, but are still valid today. They comprise theoretical suggestions and data on the nature of STM, including the notion that working memory may be defined as attention paid to features of items held in conscious awareness. The second section on levels of processing contains the very influential articles by Craik & Lockhart and by Craik & Tulving on memory research, in addition to a later article in which Craik gives a critical account of the LOP work. Craik’s third interest is in cognitive aging. The section contains two articles from the 1980s in which Craik lays out his ideas on age-related changes in memory, plus a more recent article addressing lifespan changes in cognition. The fourth section on attention and memory has two articles that report on the effects of divided attention on subsequent memory, and differences between implicit and explicit memory processes. The fifth section on cognitive neuroscience includes an early PET study probing neural correlates of LOP, and a study searching for the neural correlates of the "self" concept. Finally, the sixth section contains an article on bilingualism that explores age-related differences in executive functions as a consequence of bilingualism, and a study showing that bilingualism postpones the onset of Alzheimer’s disease. Grouping the most highly cited and groundbreaking articles of Fergus Craik in one volume, this book will be of interest to a wide spectrum of students and professional researchers.

Download or read book Divided Attention Effects on Retrieval from Episodic Memory written by Myra Annette Fernandes and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis the dual-task technique is used to infer the component processes involved in episodic memory retrieval. In each of the six experiments, participants studied a list of random words under full attention, and recalled them while performing a distracting task presented visually on a computer. Previous research suggested that divided attention (DA) during retrieval disrupts free recall for words if the distracting task also involves memory for verbal material (Fernandes & Moscovitch, 2000). The purpose of the present work was to determine more precisely which factor(s) modulated this effect, and influence retrieval success. In the first experiment I found that verbal distracting tasks, that required animacy or syllable decisions to words, produced large interference on memory. Experiments 2 and 3 showed that phonemic decisions about nonsense-words produced a similarly large interference effect on memory, that was larger than semantic decisions or size-estimations about pictures of objects. These findings support the component-process model of memory, which suggests that retrieval is largely disrupted only when there is competition for a common representational system. In the next set of experiments an alternative, reduced-resource, account of interference from DA at retrieval is considered by comparing the performance of young and old adults under DA conditions. A word-animacy distracting task interfered substantially with retrieval, but the size of the effect was not amplified in old compared to young adults. Dividing attention using an odd-digit task did not produce as large an effect, in either group. Finally, the contribution of the frontal and temporal lobes to interference effects on memory were examined. Elderly participants were divided pre-experimentally into 4 groups, determined by their scores on measures of frontal and temporal lobe function, derived from neuropsychological testing. Large interference effects on memory were produced by the animacy, but not the odd-digit distracting task. The pattern and magnitude of interference effects did not differ depending on level of temporal or frontal function. These results do not support the hypothesis that effects of DA at retrieval are due to a reduction in general processing resources, attentional capacity, or competition for memory structures in the temporal lobe.
