Systems developed to serve the information needs of crisis management should therefore accommodate the distributed nature of work in this context. Crisis management personnel often work in teams and their activities are shaped based on their interactions with each other as well as their environment. Moreover, crisis management teams tend to develop idiosyncrasies in organizing their own knowledge thereby hindering future possibilities of communication or coordination with external agencies. Keeping this in mind, the research described in this thesis considers the cognitive activities of the team in designing relevant technology for crisis management. Transactive memory is a theory put forward by Daniel Wegner in an effort to understand the group mind. The theory asserts that groups would succeed in achieving their collective tasks better if they can emphasize specialization into the work through accurate expertise judgment and thus continuously reconcile an evolving and disparate knowledge base for the common benefit of the group. This thesis will thus use the transactive memory approach in designing a prototypical decision-support system for crisis management personnel. iv TABLE OF CONTENTS LIST OF FIGURES

  • The Experience of Doing’
    Phenomenology and the Feeling of Doing: 1 Wegner on the Conscious Will Tim Bayne, Macquarie University [email protected] February 24, 2005 To appear in S. Pockett, W. P. Banks & S. Gallagher (eds) Does Consciousness Cause Behavior? An Investigation of the Nature of Volition. Cambridge, MA: MIT Press. Abstract In this paper I examine Daniel Wegner’s claim that the conscious will is an illusion. I begin by asking what Wegner might mean by “the conscious will”, and what he might mean by calling it an illusion. I then explore Wegner’s arguments for the claim that the conscious will is an illusion. I conclude that these arguments fail, and that although there is much we do not yet know about the structure of the phenomenology of agency, it is unlikely that the phenomenology of agency is illusory. 1. Introduction Given its ubiquitous presence in everyday experience, it is surprising that the phenomenology of doing—the experience of being an agent—has received such scant attention in the consciousness literature. But things are starting to change, and a small but growing literature on the content and causes of the phenomenology of first-person agency is beginning to emerge.2 One of the most influential and stimulating figures in this literature is Daniel Wegner. In a series of papers and his book The Illusion of Conscious Will (ICW) Wegner has developed an account of what he calls “the experience of conscious will”. In this paper I assess Wegner’s model of the conscious will and the claims that he makes on the basis of it.

  • The Sense of Conscious Will
    BEHAVIORAL AND BRAIN SCIENCES (2004) 27, 649–692 Printed in the United States of America Précis of The illusion of conscious will Daniel M. Wegner Department of Psychology, Harvard University, Cambridge, MA 02138. [email protected] http://www.wjh.harvard.edu/~wegner/ Abstract: The experience of conscious will is the feeling that we are doing things. This feeling occurs for many things we do, conveying to us again and again the sense that we consciously cause our actions. But the feeling may not be a true reading of what is happening in our minds, brains, and bodies as our actions are produced. The feeling of conscious will can be fooled. This happens in clinical disorders such as alien hand syndrome, dissociative identity disorder, and schizophrenic auditory hallucinations. And in people without disorders, phenomena such as hypnosis, automatic writing, Ouija board spelling, water dowsing, facilitated communication, speaking in tongues, spirit possession, and trance channeling also illustrate anomalies of will – cases when actions occur without will or will occurs without action. This book brings these cases together with research evidence from laboratories in psychology to explore a theory of apparent mental causation. According to this theory, when a thought appears in consciousness just prior to an action, is consistent with the action, and appears exclusive of salient alternative causes of the action, we experience conscious will and ascribe authorship to ourselves for the action. Experiences of conscious will thus arise from processes whereby the mind interprets itself – not from processes whereby mind creates action. Conscious will, in this view, is an indication that we think we have caused an action, not a revelation of the causal sequence by which the action was produced.

  • Daniel Wegner, the Illusion of Conscious Will (Cambridge MA: the MIT Press, 2002), Pp
    Daniel Wegner, The Illusion of Conscious Will (Cambridge MA: The MIT Press, 2002), pp. xi + 405. Anyone who retains the Cartesian faith that we know what we are doing should read this book. Wegner assembles a huge amount of evidence to show our widespread ignorance of when and how we are acting. Our failures are of two kinds. First there are cases in which we are acting but do not realize that we are. Examples include ouija board manipulation and other varieties of Victorian spiritualism; facilitated communication; water divination; and hypnotism, to which Wegner devotes a long chapter that would serve as an excellent introduction to the topic. Second come cases in which we are not acting, but think that we are. Wegner describes an experiment of his own (the ‘I-Spy’ study) in which subjects are induced to believe that they have selected a figure on a computer screen (when they haven’t) by the expedient of getting them to think about that figure a few seconds before. Perhaps such cases are unusual; more common are cases in which we are indeed acting, but in which we think that our actions are achieving far more than they in fact are. We habitually overestimate the effect that we have on objects and people around us. Indeed there is good evidence from many studies that it is a sign of mental health to overestimate one’s control over the world. If this weren’t bad enough, it also appears that, even if we do accurately understand our actions at the time, we are very likely to likely to forget or confabulate later.

  • Final TMR For
    Transactive Memory Reconstructed: Rethinking Wegner’s Research Program BRYCE HUEBNER Bryce Huebner is an Associate Professor of Philosophy at Georgetown University. His research primarily focuses on issues in in the philosophy of the cognitive, biological, and social sciences. He is the author of Macrocognition: A theory of distributed minds and collective intentionality (Oxford University Press, 2014), as well as several articles addressing issues the structure of human agency, the kinds of minds we find in our world, and the implications of cognitive scientific research for ethical theorizing. Abstract: In this paper, I argue that recent research on episodic memory supports a limited defense of the phenomena that Daniel Wegner has termed transactive memory. Building on psychological and neurological research, targeting both individual and shared memory, I argue that individuals can collaboratively work to construct shared episodic memories. In some cases, this yields memories that are distributed across multiple individuals, instead of being housed in individual brains. When we first met Otto, he was experiencing early symptoms of Alzheimer's disease (Clark & Chalmers 1998). Although he had lived in the same apartment since the 1970s, he was having a hard time getting around his beloved city. But he could still remember where to look for information, even when he couldn't remember where things were. This allowed him to use a notebook to get around. When he decided to see an exhibit at the MOMA, he could check his notebook to see where the museum was, and set out with his notebook in hand. David Chalmers (2008) has recently claimed that many people rely on iPhones in a similar way.

  • Is Conscious Will an Illusion?*
    Disputatio 16, May 2004 Is conscious will an illusion?* Jing Zhu Chinese Academy of Sciences Abstract In this essay I critically examine Daniel Wegner’s account of conscious will as an illusion developed in his book The Illusion of Conscious Will (MIT Press, 2002). I show that there are unwarranted leaps in his argument, which con- siderably decrease the empirical plausibility and theoretical adequacy of his account. Moreover, some features essential to our experience of willing, which are related to our general understanding of free will, moral responsi- bility and human agency, are largely left out in Wegner’s account of conscious will. This substantially diminishes its implications and significance for some profound philosophical issues. 1. Introduction Normally, we have the experience that we consciously will what we do: we are the authors or originators who make our actions happen. Actions are generally understood as what we voluntarily do, perform or bring about, instead of what we undergo or merely happen to us. We do things, and when we do them, we experience the actions as coming * I would like to thank Andrei Buckareff for many helpful comments on the first draft of this essay. Earlier versions of this paper were presented at The 95th Annual Meeting of the Southern Society for Philosophy and Psychology, on April 17, 2003, in Atlanta, Georgia, 2003’ APA Central Division Meeting, on April 25, 2003, in Cleveland, Ohio, and The 29th Annual Meeting of the Society for Philosophy and Psychology, on June 19, 2003, in Pasadena, California.

Hoodb aSchool of Management, Operations and Marketing, University of Wollongong bDepartment of Management, Information Systems and Quantitative Methods, Collat School of Business, University of Alabama at Birmingham Received 29 June 2017; received in revised form 3 May 2018; accepted 21 May 2018 Abstract Transactive memory systems (TMS) theory has attracted considerable attention in the scholarly fields of cognitive, organizational, and social psychology; communication; information science; and management. A central theme underlying and connecting these scholarly fields has been the role of interpersonal communication in explaining how members of dyads, groups, and teams learn “who knows what,” specialize in different information domains, and retrieve information from domain experts. However, because theoretical and empirical evidence is scattered across related, yet distinct scholarly fields, it is difficult to determine how and why communication influences TMS and related outcomes. Thus, this paper reviews literature on the relationships between communication, TMS, and outcomes in dyads, groups, and teams, and proposes avenues for future research. Keywords: Communication; Transactive memory systems 1. Introduction Transactive memory systems (TMS) theory (Wegner, 1986, 1995; Wegner, Giuliano, & Hertel, 1985) has attracted increased attention in various scholarly fields (for literature Correspondence should be sent to Vesa Peltokorpi, Faculty of Business, School of Management, Opera- tions and Marketing, University of Wollongong, Northfields Avenue, Wollongong, NSW 2522, Australia.
