Abstract

This book presents groundbreaking robotic experiments on how and why spatial language evolves. It provides detailed explanations of the origins of spatial conceptualization strategies, spatial categories, landmark systems and spatial grammar by tracing the interplay of environmental conditions, communicative and cognitive pressures. The experiments discussed in this book go far beyond previous approaches in grounded language evolution. For the first time, agents can evolve not only particular lexical systems but also evolve complex conceptualization strategies underlying the emergence of category systems and compositional semantics. Moreover, many issues in cognitive science, ranging from perception and conceptualization to language processing, had to be dealt with to instantiate these experiments, so that this book contributes not only to the study of language evolution but to the investigation of the cognitive bases of spatial language as well.

Abstract

Neglect is one of the most impressive neuropsychological disorder, for both its theoretical and clinical relevance. Besides being very common and disabling, it is highly informative for understanding normal cognitive functioning. The hallmark of neglect is the failure to attend to the contralesional hemispace. However, several studies have recently highlighted that additional deficits, not attributable to a spatial bias, are associated to the impaired contralesional hemispace processing. Moreover, manifestations of neglect tend to be particularly heterogeneous and often dissociate according to the spatial domain being investigated (e.g., body space, space within reaching, space beyond reaching, imaginal space). Heterogeneity in neglect patients also means that dissociations across different tasks in a single patient are more the rule than the exception. Evidence suggests that some of these dissociations can be readily explained by taking into account the amount of available attentional resources as a major determinant for the presence and the severity of neglect. There is no doubt that neglect patients provide a wealth of information about the functioning of systems subserving attentional orienting and spatial processing. Moreover, their performance also show that some non-spatial deficits are tightly coupled with more classic contralesional spatial deficits. It seems however still unclear to what extent these non-spatial deficits are an intrinsic characteristic of neglect or whether they are to be considered unspecific effects of the often massive brain lesions suffered by the patients. From the clinical point of view, neglect is a disorder that dramatically affects patients and their caregivers, because it severely limits the individuals’ autonomy and motor recovery after brain damage. For these reasons neglect is a disorder that is worth rehabilitating. To be effective, neglect rehabilitation should be based on the knowledge of what cognitive aspects are impaired and it should be focused on improving daily-life performance. For these reasons, it is also important to detect and quantify subtle forms of neglect.

Abstract

Background: Interacting with other people involves spatial awareness of one’s own body and the other’s body and viewpoint. In the past, social cognition has focused largely on belief reasoning, which is abstracted away from spatial and bodily representations, while there is a strong tradition of work on spatial and object representation which does not consider social interactions. These two domains have flourished independently. A small but growing body of research examines how awareness of space and body relates to the ability to interpret and interact with others. This also builds on the growing awareness that many cognitive processes are embodied, which could be of relevance for the integration of the social and spatial domains: Online mental transformations of spatial representations have been shown to rely on simulated body movements and various aspects of social interaction have been related to the simulation of a conspecific’s behaviour within the observer’s bodily repertoire. Both dimensions of embodied transformations or mappings seem to serve the purpose of establishing alignment between the observer and a target. In spatial cognition research the target is spatially defined as a particular viewpoint or frame of reference (FOR), yet, in social interaction research another viewpoint is occupied by another’s mind, which crucially requires perspective taking in the sense of considering what another person experiences from a different viewpoint. Perspective taking has been studied in different ways within developmental psychology, cognitive psychology, psycholinguistics, neuropsychology and cognitive neuroscience over the last few decades, yet, integrative approaches for channelling all information into a unified account of perspective taking and viewpoint transformations have not been presented so far. Aims: This Research Topic aims to bring together the social and the spatial, and to highlight findings and methods which can unify research across areas. In particular, the topic aims to advance our current theories and set the stage for future developments of the field by clarifying and linking theoretical concepts across disciplines. Scope: The focus of this Research Topic is on the SPATIAL and the SOCIAL, and we anticipate that all submissions will touch on both aspects and will explicitly attempt to bridge conceptual gaps. Social questions could include questions of how people judge another person’s viewpoint or spatial capacities, or how they imagine themselves from different points of view. Spatial questions could include consideration of different physical configurations of the body and the arrangement of different viewpoints, including mental rotation of objects or viewpoints that have social relevance. Questions could also relate to how individual differences (in personality, sex, development, culture, species etc.) influence or determine social and spatial perspective judgements. Many different methods can be used to explore perspective taking, including mental chronometry, behavioural tasks, EEG/MEG and fMRI, child development, neuropsychological patients, virtual reality and more. Bringing together results and approaches from these different domains is a key aim of this Research Topic. We welcome submissions of experimental papers, reviews and theory papers which cover these topics.

Abstract

The global population aged over 60 is set to rise dramatically in the coming decades. In many countries, the older population now faces the prospect of spending a quarter of their lives aged over 65, and a significant proportion will have to cope with cognitive decline associated with normal ageing or with dementia disorders. Given that these fundamental demographic changes will pose a significant challenge to health care systems, a detailed understanding of age-related cognitive and neurobiological changes is essential in helping elderly populations maintain cognitive performance. In addition, developing sensitive biomarkers to identify those at risk of developing dementia is crucial for early and effective interventions. To make inferences about the ageing process from the animal model back to the human, rigorous behavioral paradigms must be used to ensure that the same function is being examined across species. Given that similar navigational paradigms can easily be applied to humans and animals, recent years have seen an expansion of studies attempting to bridge the gap between age-related changes in animal and human spatial cognition. These studies begin to suggest that disruptions in spatial computations are among the earliest indicators of impending cognitive decline. In addition, although many animal studies have identified pathological mechanisms with paradigms involving spatial navigation, these mechanisms support many nonspatial cognitive functions as well. As a consequence, a successful characterization of how spatial processing changes in the ageing brain could reveal fundamental effects of cognitive ageing that could inform about general mechanisms underlying decline in perception, mnemonic processing and multisensory integration.

Abstract

The true revolution in the age of digital neuroanatomy is the ability to extensively quantify anatomical structures and thus investigate structure-function relationships in great detail. Large-scale projects were recently launched with the aim of providing infrastructure for brain simulations. These projects will increase the need for a precise understanding of brain structure, e.g., through statistical analysis and models. From articles in this Research Topic, we identify three main themes that clearly illustrate how new quantitative approaches are helping advance our understanding of neural structure and function. First, new approaches to reconstruct neurons and circuits from empirical data are aiding neuroanatomical mapping. Second, methods are introduced to improve understanding of the underlying principles of organization. Third, by combining existing knowledge from lower levels of organization, models can be used to make testable predictions about a higher-level organization where knowledge is absent or poor. This latter approach is useful for examining statistical properties of specific network connectivity when current experimental methods have not yet been able to fully reconstruct whole circuits of more than a few hundred neurons.

Abstract

"This book focuses on the study of the remarkable new source of geographic information that has become available in the form of user-generated content accessible over the Internet through mobile and Web applications. The exploitation, integration and application of these sources, termed volunteered geographic information (VGI) or crowdsourced geographic information (CGI), offer scientists an unprecedented opportunity to conduct research on a variety of topics at multiple scales and for diversified objectives. The Handbook is organized in five parts, addressing the fundamental questions: What motivates citizens to provide such information in the public domain, and what factors govern/predict its validity?What methods might be used to validate such information? Can VGI be framed within the larger domain of sensor networks, in which inert and static sensors are replaced or combined by intelligent and mobile humans equipped with sensing devices? What limitations are imposed on VGI by differential access to broadband Internet, mobile phones, and other communication technologies, and by concerns over privacy? How do VGI and crowdsourcing enable innovation applications to benefit human society? Chapters examine how crowdsourcing techniques and methods, and the VGI phenomenon, have motivated a multidisciplinary research community to identify both fields of applications and quality criteria depending on the use of VGI. Besides harvesting tools and storage of these data, research has paid remarkable attention to these information resources, in an age when information and participation is one of the most important drivers of development. The collection opens questions and points to new research directions in addition to the findings that each of the authors demonstrates. Despite rapid progress in VGI research, this Handbook also shows that there are technical, social, political and methodological challenges that require further studies and research."

Abstract

The Paraguayan economy did not suffer debt crises in the eighties and had significant growth rates in the second half on the seventies, but poverty remained a problem. Understanding the performance and spatial distribution of poverty and inequality over a period of more than ten years can shed new light on structural causes behind what seems to be a low growth – high poverty – high inequality trap in Paraguay. How did poverty and inequality change during the 1990s. Did inequality reduce income growth? What were the growth determinants and what are the main forces driving inequality changes? These are the questions being answered in this book.

Abstract

Recent evidence has shown many ways in which our bodies and the environment influence cognition. In this Research Topic we aim to develop our understanding of cognition by considering the diverse and dynamic relationship between the language we use, our bodily perceptions, and our actions and interactions in the broader environment. There are already many empirical effects illustrating the continuity of mind- body-environment: manipulating body posture influences diverse areas such as mood, hormonal responses, and perception of risk; directing attention to a particular sensory modality can affect language processing, signal detection, and memory performance; placing implicit cues in the environment can impact upon social behaviours, moral judgements, and economic decision making. This Research Topic includes papers that explore the question of how our bodies and the environment influence cognition, such as how we mentally represent the world around us, understand language, reason about abstract concepts, make judgements and decisions, and interact with objects and other people. Contributions focus on empirical, theoretical, methodological or modelling issues as well as opinion pieces or contrasting perspectives. Topic areas include, perception and action, social cognition, emotion, language processing, modality-specific representations, spatial representations, gesture, atypical embodiment, perceptual simulation, cognitive modelling and perspectives on the future of embodiment.

Abstract

Living at the beginning of the 21st century requires being numerate, because numerical abilities are not only essential for life prospects of individuals but also for economic interests of post-industrial knowledge societies. Thus, numerical development is at the core of both individual as well as societal interests. There is the notion that we are already born with a very basic ability to deal with small numerosities. Yet, this often called “number sense” seems to be very restricted, approximate, and driven by perceptual constraints. During our numerical development in formal (e.g., school) but also informal contexts (e.g., family, street) we acquire culturally developed abstract symbol systems to represent exact numerosities – in particular number words and Arabic digits – refining our numerical capabilities. In recent years, numerical development has gained increasing research interest documented in a growing number of behavioural, neuro-scientific, educational, cross-cultural, and neuropsychological studies addressing this issue. Additionally, our understanding of how numerical competencies develop has also benefitted considerably from the advent of different neuro-imaging techniques allowing for an evaluation of developmental changes in the human brain. In sum, we are now starting to put together a more and more coherent picture of how numerical competencies develop and how this development is associated with neural changes as well. In the end, this knowledge might also lead to a better understanding of the reasons for atypical numerical development which often has grieve consequences for those who suffer from developmental dyscalculia or mathematics learning disabilities. Therefore, this Research Topic deals with all aspects of numerical development: findings from behavioural performance to underlying neural substrates, from cross-sectional to longitudinal evaluations, from healthy to clinical populations. To this end, we included empirical contributions using different experimental methodologies, but also theoretical contributions, review articles, or opinion papers.
