Book Description
The current thesis investigated the effects of a variety of spatial and temporal factors on visual recognition memory in human adults. Continuous recognition experiments investigated the effect of lag (the number of items intervening between study and test) on recognition of a variety of stimulus sets (common objects, face-like stimuli, fractals, trigrams), and determined that recognition of common objects was superior to that of other stimulus types. This advantage was largely eradicated when common objects of only one class (birds) were tested. Continuous recognition confounds the number of intervening items with the time elapsed between study and test presentations of stimuli. These factors were separated in an experiment comparing recognition performance at different rates of presentation. D-prime scores were affected solely by the number of intervening items, suggesting an interference-based explanation for the effect of lag. The role of interference was investigated further in a subsequent experiment examining the effect of interitem similarity on recognition. A higher level of global similarity amongst stimuli was associated with a lower sensitivity of recognition. Spatial separation between study and test was studied using same/different recognition of face-like stimuli, and spatial shifts between study and test locations. An initial study found a recognition advantage for stimuli that were studied and tested in the same peripheral location. However, the introduction of eye-tracking apparatus to verify fixation resulted in the eradication of this effect, suggesting that it was an artefact of uncontrolled fixation. Translation of both face-like and fractal stimuli between areas of different eccentricity, with different spatial acuities, did decrease recognition sensitivity, suggesting a partial positional specificity of visual memory. These phenomena were unaffected by 180 degree rotation. When interfering stimuli were introduced between study and test trials, translation invariance at a constant eccentricity broke down.

Book Description
The chapters in Human Spatial Memory: Remembering Where present a fascinating picture of an everyday aspect of mental life that is as intriguing to people outside of academia as it is to scientists studying human cognition and behavior. The questions are as old as the study of mind itself: How do we remember where objects are located? How do we remember where we are in relation to other places? What is the origin and developmental course of spatial memory? What neural structures are involved in remembering where? How do we come to understand scaled-down versions of places as symbolic representations of actual places? Although the questions are old, some of the answers-in-progress are new, thanks to some innovative theorizing, solid experimental work, and revealing applications of new technologies, such as virtual environments and brain imaging techniques. This volume includes a variety of theoretical, empirical, and methodological advances that invite readers to make their own novel connections between theory and research. Scholars who study spatial cognition can benefit from examining the latest from well-established experts, as well as milestone contributions from early-career researchers. This combination provides the reader with a sense of past, present, and future in terms of spatial memory research. Just as important, however, is the value of the volume as a touchstone resource for researchers who study perception, memory, or cognition but who are not concerned primarily with the spatial domain. All readers may find the fact that this volume violates the trend toward an ever-narrowing specialization refreshing. Chapters from cognitive psychologists are alongside chapters by developmentalists and neuroscientists; results from field studies are just pages away from those based on fMRI during observation of virtual displays. Thus, the book invites integrative examination across disciplines, research areas, and methodological approaches.

Book Description
Representation of the visual and spatial properties of our environment is a pivotal requirement of everyday cognition. We can mentally represent the visual form of objects. We can extract information from several of the senses as to the location of objects in relation to ourselves and to other objects nearby. For some of those objects we can reach out and manipulate them. We can also imagine ourselves manipulating objects in advance of doing so, or even when it would be impossible to do so physically. The problem posed to science is how these cognitive operations are accomplished, and proffered accounts lie in two essentially parallel research endeavours, working memory and imagery. Working memory is thought to pervade everyday cognition, to provide on-line processing and temporary storage, and to update, moment to moment, our representation of the current state of our environment and our interactions with that environment. There is now a strong case for the claims of working memory in the area of phonological and articulatory functions, all of which appear to contribute to everyday activities such as counting, arithmetic, vocabulary acquisition, and some aspects of reading and language comprehension. The claims for visual and spatial working memory functions are less convincing. Most notable has been the assumption that visual and spatial working memory are intimately involved in the generation, retention and manipulations of visual images. There has until recently been little hard evidence to justify that assumption, and the research on visual and spatial working memory has focused on a relatively restricted range of imagery tasks and phenomena. In a more or less independent development, the literature on visual imagery has now amassed a voluminous corpus of data and theory about a wide range of imagery phenomena. Despite this, few books on imagery refer to the concept of working memory in any detail, or specify the nature of the working memory system that might be involved in mental imagery. This essay follows a line of reconciliation and positive critiquing in exploring the possible overlap between mental imagery and working memory. Theoretical development in the book draws on data from both cognitive psychology and cognitive neuropsychology. The aim is to stimulate debate, to address directly a number of assumptions that hitherto have been implicit, and to assess the contribution of the concept of working memory to our understanding of these intriguing core aspects of human cognition.

Book Description
Visual working memory allows us to temporarily maintain and manipulate visual information in order to solve a task. The study of the brain mechanisms underlying this function began more than a half century ago, with Scoville and Milner’s (1957) seminal discoveries with amnesic patients. This timely collection of papers brings together diverse perspectives on the cognitive neuroscience of visual working memory from multiple fields that have traditionally been fairly disjointed: human neuroimaging, electrophysiological, behavioural and animal lesion studies, investigating both the developing and the adult brain.

Book Description
This volume covers a broad range of current research topics addressing the function of visuospatial attention and working memory. It discusses a variety of perspectives ranging from evolutionary and genetic underpinnings to neural substrates/computational processes and the connection between attention and working memory. Contributions address the topic at the molecular, system and evolutionary scales and will be of interest to a range of audiences from animal behaviour specialists, experimental psychologists to clinicians in the field of psychiatry and neurology.

Book Description
Our everyday environments often consist of repeated spatial configurations and temporal relationships. Humans can utilize this information implicitly and automatically to guide behavior. Previous research has demonstrated how behavior adapts to repeated spatial and temporal contexts under strict laboratory conditions that may not generalize to the highly variable conditions of the real-world. Here I discuss a series of experiments that explored these limits in the domains of visual attention and visual long-term memory. Regarding visual attention, I tested for contextual cueing effects when repeated spatial contexts are only partially predictive and not globally distributed. Regarding long-term memory, I tested for recognition-induced forgetting effects when memories are unrelated in terms of semantic information but related in terms of a shared temporal context. The results of these explorations yield an improved understanding of how these psychological phenomena generalize to more realistic settings and how contextual information serves as an important source of information to guide everyday behavior.
