Previous research has extensively studied how the match between study and test context affect subsequent memory performance; however, little work has attempted to examine how visual context information provided at study affects later recollection when that context information is not re-presented at retrieval. In particular, the quality of the memory retrieved may be enhanced when highly meaningful visual context information is provided at study. In each of seven experiments in the current thesis, participants studied words presented with context information high or low in meaningful content, and on a later recognition memory test made a Remember, Know, or New response to the words presented alone. Experiment 1 showed that participants had better overall memory, specifically recollection, for words studied with pictures of intact as opposed to scrambled faces. In Experiment 2, these results were replicated and recollection was shown to be higher for words studied with versus without pictures of faces. Experiment 3 showed that participants had higher memory performance, and recollection in particular, for words studied with upright compared to inverted faces. In Experiment 4, participants showed equivalent memory for words studied with novel or familiar faces. These results suggest that recollection benefits when visual context information high in meaningful content accompanies study words, and that this benefit is not related to the novelty of the context. To further test the claim that participants engage in elaborative processes at study to bind item and context information, improving subsequent recollection, the subsequent set of experiments examined how normal, healthy aging affects participants' ability to use context information provided at study to benefit subsequent recollection. Older adults have been shown to experience deficits both in memory for context and in recollection, suggesting that they might fail to use context effectively to increase recollection, in contrast to younger adults. Experiment 5 found that younger, but not older, adults showed higher recollection for words studied with faces as compared to rectangles. To determine the type of cognitive processing required to obtain recollection benefits, and to examine whether instruction could alleviate age-related deficits, in Experiment 6, the type of processing engaged during the encoding of context-word pairs was manipulated. Younger and older adults studied words presented with a picture of a face under a surface feature or binding feature instruction condition. Both age groups showed higher recollection in the binding than surface instruction condition. Results suggest that older adults do not spontaneously engage in the processes required to boost recollection when visual context information is provided at study, although instructional manipulation during encoding lessens this deficit. The final experiment used functional Magnetic Resonance Imaging (fMRI) to examine the neural correlates of recollection, specifically testing the hypothesis that sensory-specific reactivation of context information occurs during item recollection. In Experiment 7, brain activation for Remember responses given to words studied with and without meaningful context information was compared. Behaviourally, 8 of the 14 participants showed a higher proportion of Remember responses to words studied with faces than scrambled faces, and 6 did not. Whole brain analysis showed that, for only those participants who showed higher memory performance for words studied with faces, activation in the fusiform gyrus and hippocampus was higher, and a region-of-interest analysis showed increased activation in the functionally-defined FFA (identified in a localizer task), for Remember responses given to words studied with faces compared to scrambled faces. A regression analysis additionally showed that activation in the fusiform gyrus increased as the relative recollection benefit for words studied with meaningful (face) compared to non-meaningful (scrambled face) context information increased across participants. Results suggest that encoding v context can influence the pattern of recollection responses on a recognition task and that sensory-specific reactivation is related to behavioural performance. The findings of these experiments suggest that participants can use context information high in meaningful content at study to improve subsequent recollection and I suggest that this involves the use of elaborative processes at encoding that integrates item and meaningful contexts. Such recollection benefits can also be observed in older adults when they are provided experimental instructions to bind item and context at encoding. In addition, the brain regions used to process context information are reactivated at retrieval and, importantly, that this neural pattern determines whether a boost in recollection, from the encoding manipulation, is observed. Participants can thus use context information provided at study to boost subsequent recollection, and I suggest that this involves cognitive processes that bind item and context information at encoding and the reactivation of sensory-specific brain regions at retrieval.

Available in PDF, EPUB and Kindle. Book excerpt: "The overarching aim of this thesis is to investigate the influence of scenes on the recognition of objects. In pursuit of this objective, two studies were performed using the same old-new recognition task. The first of the two studies investigated behavioral responses and the second included an additional functional component with electrophysiological recordings. Objectives. The first study elucidated how features of an object interact with other potential factors, such as the context in which a target object is seen, as well as the role of individual characteristics of the observer. The aims of the first study were to examine: i) how context influences recognition memory; and ii) how this effect is influenced by the familiarity of objects and the manner by which subjects process information (i.e., cognitive style). The second study investigated the underlying mechanisms of the influence of context on the recognition of objects in healthy subjects and aimed to: i) examine the effect of scene on object recognition by extracting the functional brain signals previously shown to be associated with familiarity and recollection; and ii) to examine whether the influence of scenes on old and lure objects was defined by dissociable mechanisms. Methods. The stimuli of both studies were composed of objects appearing in various scenes. At recognition, half of the objects that were previously studied (i.e. old) were placed in either the same scene or in a different scene. The remaining objects were novel, and resembled the previously studied objects (i.e., lures). Lures appeared either in the same scene as a similar, previously-studied object, or in a distinct scene. For the first study the cognitive style of the subjects was assessed with the group embedded figure test (GEFT), which determines whether subjects have a field dependent (FD) (i.e. sensitive to context) or field independent (FI) way of processing information. Results. The results of the first experiment demonstrated that the similarity of scenes increased the feeling of familiarity of objects, that is, the likelihood of believing that an objects was previously studied (i.e., old). In FD subjects, the effect of scene was the same for familiar and unfamiliar objects, in contrast to FI subjects where the effect of scene was found only for unfamiliar objects. The context thus influences the memory of an object, and intriguingly, individuals who are less sensitive to context still use information gathered from the scene when the presented object is unfamiliar. The second experiment indicated that the influence of scenes on object recognition was driven by a process of familiarity, but that a recollection process may also be influential in the effect of scene. This latter finding suggests that the effect of scene underlying true (i.e., hits) and false recognition (i.e., false alarms) of objects is defined by distinct mechanisms. Conclusions. Similarity of scenes influence the recognition of objects as showcased by an overall increase of 'old' responses. Thus, the similarity of scenes influences both responses, hits and false alarms, and this influence of scenes is interacting with the perceived level of object familiarity and the cognitive profile of an individual. In addition, the event-related potentials further corroborate that the influence of scenes on object recognition is driven not only by familiarity, but also by a recollection process. " --

Available in PDF, EPUB and Kindle. Book excerpt: People sometimes remember events that never happened. These illusory or false memories have important practical implications in various aspects of everyday life, and also have significant theoretical implications for cognitive and neuropsychological models of memory. Cognitive psychologists and neuropsychologists have long been aware of false recognition, confabulation, and related kinds of memory distortions, but during the past several years research on these topics has increased rapidly. In recognition of this emerging domain of interest, this special issue of Cognitive Neuropsychologyis devoted to the cognitive neuropsychology of false memories. Edited by Daniel L. Schacter, the special issue features experimental and theoretical contributions from leading cognitive psychologists, neuropsychologists, and neurologists that explore such issues as false recognition after frontal lobe damage, the nature of confabulation, amnesia and false memories, physiological correlates of memory illusions, memory distortions in normal and abnormal aging, and computational models of true and false memories. gical correlates of memory illusions, memory distortions in normal and abnormal aging, and computational models of true and false memories.

Download or read book The Processing of Memories PLE Memory written by Norman E. Spear and published by Psychology Press. This book was released on 2014-05-09 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1978, this volume contains the evidence that is most crucial for our understanding the processes of forgetting and retention. Organized in terms of problem areas and issues that are particularly pertinent to understanding these processes, the book deals with both animal and human studies. The author begins by defining the topic and reviewing its historical development. A theoretical orientation follows, and then the author begins to address the major factors that determine what is, and what is not, remembered. Although we cannot yet specify the principles from which we can predict when an episode, once learned, will be remembered well or forgotten entirely, the author demonstrates that such principles are not that far away. He considers the issues that must be resolved before such principles are established, and in the course of doing so covers the major research on why we remember events and why they are forgotten.
Download or read book The Foundations of Remembering written by James S. Nairne and published by Psychology Press. This book was released on 2011-12-06 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Foundations of Remembering presents a collection of essays written by top memory scholars in honor of Henry L. Roediger III. The chapters were originally delivered as part of the "Roddyfest" conference held in March 2005 to celebrate Purdue University's awarding of an honorary doctor of letters to Roediger in recognition of his many contributions to the field of psychology. Authors were given a simple charge: choose your own topic, but place your work in historical context. Roediger is fascinated by the intellectual lineage of ideas, so addressing historical "foundations" seemed a fitting tribute. The Chapters contained in this volume help to establish the foundations of remembering, circa the first decade of the 21st century, as perceived by some of the leading memory researchers in the world. Not surprisingly, each of the chapters touches on Roediger's research as well, largely because his work has helped to define and clarify many topics of interest to the memory field. The Foundations of Remembering is intended for a wide audience: students, scholars, and anyone interested in exploring the historical and conceptual roots of modern memory theory.

Aspects of Memory gives a clear introduction by some of the world's leading experts. The first two chapters of set past theorising about memory in an historical context and identify the major aspects of memory to be captured by any theoretical account. Later chapters go on to discuss theoretical accounts of working memory, the development of memory, implicity memory, and context-dependent memory. A final section discusses the respective strengths and problems of naturalistic and laboratory research on memory.Aspects of Memory provides an excellent authoritative textbook of current approaches to memory.
Download or read book Remembering Faces in Different Places written by Shahnaz Koji and published by . This book was released on 2013 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: How context affects memory is the central focus of the six experiments making up this PhD thesis. In these experiments, pictures of faces were presented in an incidental encoding phase, paired with a variety of indoor and outdoor context scenes (e.g., park, supermarket, swimming pool), and a recognition memory test ensued in which faces were paired with either the same context (exact same context the face was paired with at encoding), switched context (a context that was presented at study, but not presented with that particular face), or new context (a context never before seen), relative to encoding. In Experiment 1, the importance of instructions at encoding was examined by manipulating instructions to either actively link or passively view the face and context at encoding. Maintaining the same context as at encoding reliably enhanced overall detection, and recollection, of studied faces relative to a new context, replicating the known context reinstatement (CR) effect. There was also a reliable memory benefit for faces paired at test with the same relative to a switched context, indicating a context specificity (CS) effect on memory. Encoding instructions to either actively link, or passively view, face-context pairs during encoding did not influence the presence or magnitude of the CR or CS effects, suggesting that linking of target + context may occur spontaneously. In Experiment 2, dividing attention did not influence CR, but did eliminate the CS effect on overall memory. Findings suggest that the general boost to memory from reinstating an old relative to a totally new context at test is robust, though linking specific contexts to targets is hampered when attention is limited during encoding. In Experiments 3 and 4, familiarity of the face to the observer interacted with context effects. In Experiment 3, face familiarity was manipulated by presenting famous versus non-famous faces during encoding and an attenuated CR effect was observed for famous relative to non-famous (unfamiliar) faces, though CS remained. In Experiment 4, degree of familiarity was controlled by pre-exposing the study faces 0, 1, 3, or 10 times prior to the study phase. After just one pre-exposure to an unfamiliar face, the CR effect was reduced. Experiment 5 examined whether distinctive faces were less susceptible to context effects relative to similarly familiar, but less distinctive, faces. CR and CS effects were predicted for out-group faces (Caucasian faces for Asian participants and Asian faces for Caucasian participants), and a reduction in both CR and CS for in-group faces (Caucasian faces for Caucasian participants and Asian faces for Asian participants). Results indicated no difference in CR or CS across the conditions, suggesting that distinctiveness may not be an important factor in mediating context effects. The final experiment examined how the expectancy of a face + context pairing influenced CR and CS effects, even when the target face was familiar. There were robust CR and CS effects for faces when these were repeatedly paired with a specific context during study, but a loss of both effects when faces were paired with varying contexts during study. Results extend our current knowledge regarding the role of context in memory and supports memory models that suggest context information presented at test acts as a cue that uniquely specifies a particular target.

Download or read book Distinctiveness and Memory written by R. Reed Hunt and published by Oxford University Press. This book was released on 2006-04-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research relevant to the topic of distinctiveness and memory dates back over 100 years and boasts a literature of well over 2,000 published articles. Throughout this history, numerous theories of distinctiveness and memory have been offered and subsequently refined. There has, however, never been a book that brings this rich history together with the latest research. This volume is the first to present an historical overview, the results of the current research, and several new theories on distinctiveness and memory. Each chapter contains a review of the relevant literature and latest research on its topic. The book includes sections that cover basic theory and behavioral research on distinctiveness, bizarreness effects, distinctiveness effects on implicit memory, the development of distinctiveness across the lifespan, distinctiveness in social context, and the neuroscience of distinctiveness and memory. In the concluding chapter, Fergus Craik offers his current perspective on distinctiveness and evaluates the various other theories of distinctiveness presented in the volume. Distinctiveness and Memory will be a valuable resource for student and professional researchers in neuroscience and cognitive, developmental, and social psychology.
