'Working Memory, Thought, and Action' is the magnum opus of one of the most influential cognitive psychologists of the past 50 years. This new volume on the model he created discusses the developments that have occurred within the model in the past twenty years, and places it within a broader context.

Cowan's revisiting of the magic number is very timely and the case he makes for a more moderate number than seven is persuasive. It is also appropriate to frame his case within a theoretical context, since this will influence what evidence to include and how to interpret it. He presents his model however, as a contrast to the working memory model of Baddeley. I suggest that this reflects a misinterpretation of our model resulting in a danger of focusing attention (...) on pseudo-problems rather than genuine disparities between his approach and my own.

Over 100 years ago, Frances Galton began the empirical study of autobiographical memory by devising a technique in which he explored the capacity for a cue word to elicit the recollection of events from earlier life (Galton, 1883). After a century of neglect, the topic began to re-emerge, stimulated by the work of Robinson (1976) using the technique on groups of normal subjects, by Crovitz’s work on its application to patients with memory deficits (Crovitz & Schiffman, 1974), and by the (...) detailed diary study of her own autobiographical memory carried out by Marigold Linton (Linton, 1975). This early wave of interest was focused by Rubin’s edited book on the topic (Rubin, 1986) which captured a broad and growing interest in autobiographical memory. This trend was reflected very strongly in the submissions to the second conference on Practical Aspects of Memory, in which the study of autobiographical memory represented one of the major strands (Gruneberg, Morris & Sykes, 1988), featuring prominently in both the opening and concluding addresses (Baddeley, 1988; Neisser, 1988).

The term 'episodic memory' refers to our memory for unique, personal experiences, that we can date at some point in our past - our first day at school, the day we got married. It has again become a topic of great importance and interest to psychologists, neuroscientists, and philosophers. How are such memories stored in the brain, why do certain memories disappear (especially those from early in childhood), what causes false memories (memories of events we erroneously believe have really taken (...) place)? Since Endel Tulving's classic book 'Episodic memory' (OUP, 1983) very few books have been published on this topic. In recent years however, many of the assumptions made about episodic memory have had to be reconsidered as a result of new techniques, which have allowed us a far deeper understanding of episodic memory. In 'Episodic memory: new directions in research' three of the worlds leading researchers in the topic of memory have brought together a stellar team of contributors from the fields of cognitive psychology, neuropsychology, and neuroscience, to present an account of what we now know about about this fundamentally important topic. The list of contributors includes, amongst others, Daniel Schacter, Richard Morris, Fareneh Vargha-Khadem, and Endel Tulving. The work presented within this book will have a profound effect on the direction that future research in this topic will take. (shrink)

Traditionally economists have based their economic predictions on the assumption that humans are super-rational creatures, using the information we are given efficiently and generally making selfish decisions that work well for us as individuals. Economists also assume that we're doing the very best we can possibly do - not only for today, but over our whole lifetimes too. But increasingly the study of behavioural economics is revealing that our lives are not that simple. Instead, our decisions are complicated by our (...) own psychology. Each of us makes mistakes every day. We don't always know what's best for us and, even if we do, we might not have the self-control to deliver on our best intentions. We struggle to stay on diets, to get enough exercise and to manage our money. We misjudge risky situations. We are prone to herding: sometimes peer pressure leads us blindly to copy others around us; other times copying others helps us to learn quickly about new, unfamiliar situations. This Very Short Introduction explores the reasons why we make irrational decisions; how we decide quickly; why we make mistakes in risky situations; our tendency to procrastination; and how we are affected by social influences, personality, mood and emotions. The implications of understanding the rationale for our own financial behaviour are huge. Behavioural economics could help policy-makers to understand the people behind their policies, enabling them to design more effective policies, while at the same time we could find ourselves assaulted by increasingly savvy marketing. Michelle Baddeley concludes by looking forward, to see what the future of behavioural economics holds for us.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable. (shrink)

The papers in this series of five volumes provide a snapshot of current trends in European Cognitive Science. Each of the volumes deals with problems in cognitive science from a different perspective, covering the interacting disciplines of cognitive psychology, logic and linguistics, human-computer interaction, neuroscience and artificial intelligence respectively. Linguistics is concerned with the structure and use of languages, and logic with the form and correctness of argumentation in ordinary and scientific language. The two fields are presented with respect to (...) their role in cognitive science and artificial intelligence: How are they realised by psychological mechanisms or biological processes on the one hand or programmed or wired in machines on the other. The contributions in this volume give introductions to the state-of-the-art, emphasizing the analysis of complexity and flexibility in logic and language in the framework of classical approaches (Chapters 3, 4, 5, 7). At the same time some contributions present a broader perspective in which an integration of the formal structure with the structure of the processing systems might be possible (Chapters 2 & 6). In this context, the differences and the perspectives of the classical approaches on the one hand and of connectionist approaches on the other are compared.

La traduction apparaît comme un domaine majeur de recherche dans les sciences humaines et sociales depuis deux ou trois décennies, suscitant une abondante production scientifique. A la fois technique linguistique et outil potentiellement puissant de médiation culturelle, elle constitue le type de transfert culturel par excellence, et à ce titre a attiré l’attention des chercheurs en études culturelles. Cet article passe en revue quelques-uns des travaux-clés dans ce domaine, leurs apports, et la manière dont ils ont sorti les études traductologiques (...) de leur tour d’ivoire linguistique et philologique pour en faire un objet d’étude pleinement en prise avec des questions sociétales plus larges de production et de circulation non seulement de textes mais d’idées, de discours et de modèles, dans lesquelles le traducteur est invité dorénavant à assumer sa responsabilité de « passeur » pas forcément neutre. Cette nouvelle interdisciplinarité a incontestablement apporté un dynamisme et des perspectives nouvelles à la traductologie (et vice-versa) ; cependant, elle soulève la question des compétences requises pour aborder ces thématiques, et celle des limites disciplinaires. Si l’ouverture de la traduction en tant qu’objet d’étude apparaît comme un enrichissement, l’apport de la notion de traduction comme méthode et comme modèle d’échanges culturels doit encore faire ses preuves, malgré l’existence de plusieurs tentatives stimulantes allant dans ce sens.

Ruchkin et al.'s theoretical conclusions reflect two venerable fallacies. They confound an experimental paradigm with a theoretical concept, and they assume that features of the paradigm that are most readily detected by their methods provide an adequate account of the operation of the theoretical system. This results in a simplistic theory that does not do justice to the richness of the available data.

This paper explores the changes in cognitive function which occur as someone "loses consciousness" under anesthesia. Seven volunteers attempted a categorization task and a within-list recognition test while inhaling air, 0.2% isoflurane, and 0.4% isoflurane. In general, performance on these tests declined as the dose of anesthetic was increased and returned to baseline after 10 min of breathing air. A measure of auditory evoked responding termed "coherent frequency" showed parallel changes. At 0.2% isoflurane, subjects could still identify and respond to (...) category exemplars but showed impaired short-term memory function. Electrical stimulation at 0.4% isoflurane, intended to mimic the arousing effects of surgery, had a small, beneficial effect on performance. A mean of 63% of category exemplars was identified at this stage, but recognition memory for those exemplars was at chance on recovery. There was no evidence for learning of words presented at 0.8% isoflurane. (shrink)

In this study bibliometric mapping method was employed to visualise the current research trends and the impact of the two most influential models of working memory, namely: A. D. Baddeley and G. J. Hitch’s multicomponent working memory model and N. Cowan’s embedded-processes model of working memory. Using VOSviewer software two maps were generated based on the index-term words extracted from the research papers citing Baddeley and Cowan, respectively. The maps represent networks of co-occurrences of index terms and can (...) be interpreted as an indication of the main research fields related to the examined models of WM. The results of the analysis revealed that the spheres of influence of the two main conceptualisations of WM are rather different than similar. Although the first two clusters, i.e. “brain mapping” and “higher-level cognition and development” are present in both maps, their relative importance varies. The remaining clusters are unique to each map. Baddeley’s theory seems to have a greater influence on “neuropsychology”, while Cowan’s theory - on basic research on “biological systems”, including the nervous system in humans and animals. The second difference between these theories concerns their relations to functions and dysfunctions associated with particular sensory modalities: in Baddelay’s theory with the “auditory modality” cluster, and in Cowan’s - with the “visual modality” one.

This paper explores a remarkable convergence of ideas and evidence, previously presented in separate places by its authors. That convergence has now become so persuasive that we believe we are working within substantially the same broad framework. Taylor's mathematical papers on neuronal systems involved in consciousness dovetail well with work by Newman and Baars on the thalamocortical system, suggesting a brain mechanism much like the global workspace architecture developed by Baars (see references below). This architecture is relational, in the sense (...) that it continuously mediates the interaction of input with memory. While our approaches overlap in a number of ways, each of us tends to focus on different areas of detail. What is most striking, and we believe significant, is the extent of consensus, which we believe to be consistent with other contemporary approaches by Weiskrantz, Gray, Crick and Koch, Edelman, Gazzaniga, Newell and colleagues, Posner, Baddeley, and a number of others. We suggest that cognitive neuroscience is moving toward a shared understanding of consciousness in the brain. (shrink)

It appears to be a straightforward implication of distributed cognition principles that there is no integrated executive control system (e.g. Brooks 1991, Clark 1997). If distributed cognition is taken as a credible paradigm for cognitive science this in turn presents a challenge to volition because the concept of volition assumes integrated information processing and action control. For instance the process of forming a goal should integrate information about the available action options. If the goal is acted upon these processes should (...) control motor behavior. If there were no executive system then it would seem that processes of action selection and performance couldn’t be functionally integrated in the right way. The apparently centralized decision and action control processes of volition would be an illusion arising from the competitive and cooperative interaction of many relatively simple cognitive systems. Here I will make a case that this conclusion is not well-founded. Prima facie it is not clear that distributed organization can achieve coherent functional activity when there are many complex interacting systems, there is high potential for interference between systems, and there is a need for focus. Resolving conflict and providing focus are key reasons why executive systems have been proposed (Baddeley 1986, Norman and Shallice 1986, Posner and Raichle 1994). This chapter develops an extended theoretical argument based on this idea, according to which selective pressures operating in the evolution of cognition favor high order control organization with a ‘highest-order’ control system that performs executive functions.

My case study of Heart of Darkness analyzes the role of image schemas in shaping narrative macrostructures and in organizing literary metaphor systems. Assuming that we can reconstruct global story meaning from local image-schematic metaphors, I propose a model in which compound gestalts represent major aspects of the plot-defining macrostructure. It emerges as salient textual cues progressively add up to a scaffold of image-schematic elements that represent the event's overall texture, its "plot-gene". The rich metaphor system of Heart of Darkness (...) throws into relief the amazing range of literary functions rooted in this image-schematic plot-gene, including plot mnemonics, inference, metaphor networks, and clustering of propositional knowledge, megametaphor, focalizing and viewpoint effects, irony, as well as mood contours. Progressing toward a cognitive model of narrative, I will argue that reading involves a mental simulation of how image schemas interact topologically to produce emergent effects. I dub the imagistic substrate of this simulation the "mental (story) sketchpad," following Baddeley (1986). (shrink)

This chapter examines the stages of processing meta‐theory (SPM) that has guided construction of theories in psychology during the past 350 years, from philosopher René Descartes in seventeenth‐century France to neuropsychologists Carl Wernicke and Paul Broca in nineteenth‐century Europe to psychologists Dominic Massaro and Alan Baddeley in late twentieth‐century America and Britain. The most basic SPM assumptions are that processing and storage of information take place within a finite number of autonomous modules or stages, and that some stages are (...) sequentially ordered with respect to others. Flowcharts typically summarize these assumptions. The traditional stages of processing for verbal information are comprehension, storage, retrieval, and production. SPM flowcharts can add new stages and can alter old labels to represent new types of information processing, but whatever the labels, the stages must be finite in number, distinct, independent, and sequentially ordered between input and output.

Ten cerebellar patients were compared to 10 control subjects on a verbal working memory task in which the phonological similarity of the words to be remembered and their modality of presentation were manipulated. Cerebellar patients demonstrated a reduction of the phonological similarity effect relative to controls. Further, this reduction did not depend systematically upon the presentation modality. These results first document that qualitative differences in verbal working memory may be observed following cerebellar damage, indicating altered cognitive processing, even though behavioral (...) output as measured by the digit span may be within normal limits. However, the results also present problems for the hypothesis that the cerebellar role is specifically associated with articulatory rehearsal as conceptualized in the Baddeley–Hitch model of working memory.

The goal of our target article is to establish that electrophysiological data constrain models of short-term memory retention operations to schemes in which activated long-term memory is its representational basis. The temporary stores correspond to neural circuits involved in the perception and subsequent processing of the relevant information, and do not involve specialized neural circuits dedicated to the temporary holding of information outside of those embedded in long-term memory. The commentaries ranged from general agreement with the view that short-term memory (...) stores correspond to activated long-term memory (e.g., Abry, Sato, Schwartz, Loevenbruck & Cathiard [Abry etal.], Cowan, Fuster, Grote, Hickok & Buchsbaum, Keenan, Hyönä & Kaakinen [Keenan et al.], Martin, Morra), to taking a definite exception to this view (e.g., Baddeley, Düzel, Logie & Della Sala, Kroger, Majerus, Van der Linden, Colette & Salmon [Majerus et al.], Vallar).

This paper examines the perceived ethical values of Malaysian managers. It is based on the opinions of 15 hypothetical ethical/unethical business situations from the 81 managers who agreed to participate in the survey. The findings of this study showed that these Malaysian managers have high ethical values. However 53% of the respondents believed that the ethical standards of today are lower than that of 15 years ago. Apparently, this is related to the existence of many unethical business practices prevalent in (...) the modern business world. The behavior of one's immediate superior is the most important factor in influencing managers to commit unethical practices. The results also indicate only a slight variation among the managers in terms of perceived ethical values by virtue of job position, job specialization, type of business activity or the size of the business organization.

The point of formalisation is to model various aspects of natural language. Perhaps the main use to which formalisation is put is to model and explain inferential relations between different sentences. Judged solely by this objective, a formalisation is successful in modelling the inferential network of natural language sentences to the extent that it mirrors this network. There is surprisingly little literature on the criteria of good formalisation, and even less on the question of what it is for a formalisation (...) to mirror the inferential network of a natural language or some fragment of it. This paper takes some exploratory steps towards a quantitative account of the main ingredient in the goodness of a formalisation. We introduce and critically examine a mathematical model of how well a formalisation mirrors natural-language inferential relations. (shrink)
