Available in PDF, EPUB and Kindle. Book excerpt: Dual-process models of recognition memory propose that recognition memory can be supported by either a general sense of familiarity or the recollection of the encoding context. One source of evidence supporting dual-process models comes from event-related potential (ERP) studies of recognition memory, which have identified distinct patterns of neural activity associated with familiarity and recollection (the mid frontal and left parietal old/new effects, respectively). In this thesis, dual-process accounts of recognition memory were investigated in a series of ERP studies using three categories of stimulus: previously unknown faces, famous faces, and names. For previously unknown faces, familiarity was associated with activity over posterior scalp electrodes while recollection was associated with topographically dissociable activity over anterior electrodes. These dissociable patterns of activity support dual-process models. However, the typical pattern of old/new effects was only observed for stimuli associated with pre-existing representations (i.e., names and famous faces), suggesting that the presence/absence of pre-existing representations may determine the particular retrieval processes that support recognition memory. Furthermore, recollection was associated with two different patterns of activity (anterior and left parietal effects), suggesting that recollection is not a homogenous process. Dual-process theories may represent an important starting point for investigating recognition memory, but neither familiarity nor recollection appear to be functionally homogenous processes when theorizing is constrained by the analysis of scalp recorded electrophysiological activity.

Book excerpt: This study provides a better understanding of contributing factors to age differences in human episodic memory. A recurrent finding in recognition memory is that older adults tend to have lower overall accuracy and tend to make fewer false-alarm errors in judging new items, relative miss errors (Coyne, Allen & Wickens, 1986; Danziger, 1980; Poon and Fozard 1980). Two possible causes for decline in these abilities include an age-related decrement in speed of processing (Salthouse 1991) and changes in information processing ability due to entropy (Allen, Kaufman, Smitch, & Propper 1998a; Mallik et al., in preparation). Additionally, age differences may be partially explained by a tendency for older adults to exhibit a conservative response bias. Surprisingly this study found no age-related differences in recognition memory accuracy, and older adults did not show a more conservative response bias. Due to these null results for age, the study examined the role of response bias (propensity to indicate a probe as being recognized, or new) on recognition memory accuracy and the role of the release from proactive interference (PI) across age. This study introduces a new ERP (Event-Related Potential) component to measure the recognition of "miss" responses called "FN400 Below Threshold." This component, when looked at collapsed across Experiment 1 & Experiment 2 was positively correlated to behavioral accuracy suggesting that a more conservative response criterion hurts overall behavioral accuracy. Experiment 2 found that words learned from four categories were easier to remember than words from a single category due to a reduction in interference across items. This effect was found for both age groups.

Download or read book Facing the Other Novel Theories and Methods in Face Perception Research written by Davide Rivolta and published by Frontiers Media SA. This book was released on 2016-04-08 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: We rely heavily on faces during social interactions. Humans possess the ability to recognise thousands of people very quickly and accurately without effort. The serious social difficulties that follow abnormalities of the face recognition system (i.e., prosopagnosia) strongly underline the importance of typical face skills in our everyday life. Over the last fifty years, research on prosopagnosia, along with research in the healthy population, has provided insights into the cognitive and neural features behind typical face recognition. This has also been achieved thanks to non-invasive neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI), Electroencephalography (EEG), Magnetoencephalography (MEG), Diffusion Tensor Imaging (DTI) and Transcranial Magnetic Stimulation (TMS). However, there is still much debate about the cognitive and neural mechanisms of face perception. In the current “Research Topic” we plan to gather experimental works, opinions, commentaries, mini-reviews and reviews that focus on new or novel theories and methods in face perception research. Where is the field at the moment? Do we need to re-think the experimental procedures we have adopted so far? Again, what kind of techniques (or combination of them) and analysis methods will be important in the future? From the experimental point of view we encourage both behavioural and neuroimaging contributions (e.g., fMRI, EEG, MEG, DTI and TMS). Despite the main emphasis on face perception, memory and identification, we will also consider original works that focus on other aspects of face processing, such as expression recognition, attractiveness judgments and face imagery. In addition, animal investigations and experimental manipulations that alter face recognition abilities in typical human subjects (e.g., hypnosis) are also welcome. Overall, we are proposing a Research Topic that looks at face processing using different perspectives and welcome contributions from different domains such as psychology, neurology, neuroscience, cognitive science and philosophy. The current “Research Topic” evolved over the desire to acknowledge the relatively recent loss of three giants in the field: Drs. Shlomo Bentin, Truett Allison and Andy Calder. We dedicate this “Research Topic” to them and their pioneering studies.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The study investigates long-term recognition memory in congenital prosopagnosia (CP), a lifelong impairment in face identification that is present from birth. Previous investigations of processing deficits in CP have mostly relied on short-term recognition tests to estimate the scope and severity of individual deficits. We firstly report on a controlled test of long-term (one year) recognition memory for faces and objects conducted with a large group of participants with CP. Long-term recognition memory is significantly impaired in eight CP participants (CPs). In all but one case, this deficit was selective to faces and didn't extend to intra-class recognition of object stimuli. In a test of famous face recognition, long-term recognition deficits were less pronounced, even after accounting for differences in media consumption between controls and CPs. Secondly, we combined test results on long-term and short-term recognition of faces and objects, and found a large heterogeneity in severity and scope of individual deficits. Analysis of the observed heterogeneity revealed a dissociation of CP into subtypes with a homogeneous phenotypical profile. Thirdly, we found that among CPs self-assessment of real-life difficulties, based on a standardized questionnaire, and experimentally assessed face recognition deficits are strongly correlated. Our results demonstrate that controlled tests of long-term recognition memory are needed to fully assess face recognition deficits in CP. Based on controlled and comprehensive experimental testing, CP can be dissociated into subtypes with a homogeneous phenotypical profile. The CP subtypes identified align with those found in prosopagnosia caused by cortical lesions; they can be interpreted with respect to a hierarchical neural system for face perception.

Book excerpt: BORB provides a set of standardised procedures for assessing neuropsychological disorders of visual object recognition, based on tests developed in the cognitive neuropsychological literature. The tests are introduced in terms of cognitive neuropsychological analyses of object recognition, and guidance is given concerning test use and interpretation. The tests assess low-level aspects of visual perception (using same-different matching of basic perceptual features, such as orientation, length, position and object size), intermediate visual processes (e.g., matching objects different in viewpoint), access to stored perceptual knowledge about objects (object decision), access to semantic knowledge (function and associative matches) and access to names from object (picture naming). BORB will serve as an invaluable companion test battery to the PALPA test of language ability.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with a simplified and comprehensive account of the cognitive and neural bases of face perception in humans. Faces are ubiquitous in our environment and we rely on them during social interactions. The human face processing system allows us to extract information about the identity, gender, age, mood, race, attractiveness and approachability of other people in about a fraction of a second, just by glancing at their faces. By introducing readers to the most relevant research on face recognition, this book seeks to answer the questions: “Why are humans so fast at recognizing faces?”, “Why are humans so efficient at recognizing faces?”, “Do faces represent a particular category for the human visual system?”, What makes face perception in humans so special?, “Can our face recognition system fail”?. This book presents the author’s findings on face perception during his research studies on both normal subjects and subjects with prosopagnosia, a neurological disorder characterized by the inability to recognize faces. The book describes two known forms of prosopagnosia: acquired prosopagnosia, which is the result of a brain lesion, and congenital prosopagnosia, which refers to a lifelong, developmental impairment of face recognition. Written in a comprehensive and accessible style, this book addresses both experts (cognitive scientists, psychologists, neuroscientists and computer scientists) and the general public, and aims at raising awareness for a debilitating face recognition disorder, such as prosopagnosia, which is often ignored or misdiagnosed as autism, with serious consequences for the affected persons and their families.

Available in PDF, EPUB and Kindle. Book excerpt: In this ground-breaking book, distinguished consultant clinical neurophysiologist Michael Glasby turns to the Bible to ask whether the practices of the Levitical priesthood might in any way have shared features of what we now commonly call ‘public healthcare’, contributing to the well-being of individuals and society. Is it the case that the priesthood understood some rudimentary elements of healthcare, or is this commonly held view merely the result of modern opinion formed (perhaps inappropriately) through an accumulation of later redaction and exegesis?
Download or read book The Development of Face Processing written by Gudrun Schwarzer and published by Hogrefe & Huber Publishing. This book was released on 2003 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book draws together, for the first time, the latest scientific findings from leading international researchers on how face recognition develops. It is only in recent years that methods acceptable in experimental psychology have been developed for studying this vital and unique process. While other publications have concentrated on computer modeling and of face processing and the like, this one is unique in that it looks at fundamental (and so far unanswered) questions such as: What are the roots of and reasons for our ability to recognize faces? How much of this ability is learned and how much innate? By connecting studies on face processing in infancy with those on the development of face processing, it thus bridges the gap between face processing research and visual perceptual development. Leading researchers from USA and Europe who have conducted pioneering work in these domains describe results and anticipate future inquiry, covering topics such as fundamental cognitive abilities in infancy, development of face processing from infancy to adulthood, and the effects of expertise on face recognition.
