Tiivistelmä Tämä väitöskirja pyrkii luomaan uutta tietoa hajautetuista tuotekehitys- ja tutki- mustiimeistä transaktiivisen muistin teoriasta käsin. Sen mukaan ihmiset saatta- vat, sen sijaan että itse pyrkivät muistamaan asioita, pitää muistissaan sen kuka on minkäkin alueen ekspertti ja ottamaan heihin yhteyttä tarvittaessa. Tutkimus pe- rustuu hypoteesiin jonka mukaan yksinkertaisissa tehtävissä hyvin suoriutuvalla tiimillä voi olla yksinkertainen transaktiivinen muistijärjestelmä, kun taas moni- mutkaisissa tehtävissä tehokkaiden tiimien transaktiiviset muistijärjestelmät ovat pidemmälle kehittyneitä. Työssä tarkastellaan kolmea tutkimuskysymystä: (1) millaisia ovat piirteiltään hajautettujen tuotekehitysryhmien transaktiiviset muistijärjestelmät, (2) kuinka muistijärjestelmät tällaisissa yhteyksissä kytkeytyvät tiimien kommunikaatioon (taajuuteen ryhmän jäsenten välillä) ja (3) onko kehittynyt transaktiivinen muisti- järjestelmä välttämätön ehto myös yksinkertaisissa tuotekehitystehtävissä? Työssä tarkasteltiin kahta hajautettua ohjelmistokehitystiimiä. Molemmissa tapa- uksissa transaktiiviset muistijärjestelmät olivat vain paikallisia; kaukaisten tiimien osien tietämyksestä jäsenillä oli harvoin mitään tietoa. Ensimmäisellä case- tiimeistä oli vain yksinkertaisia tehtäviä, joista se suoriutui hyvin. Pitkälle kehit- tynyt transaktiivinen muisti ei siis ole yksinkertaisissa tehtävissä välttämättö- myys. Tämän löydöksen tulisi teoreettisesti olla yleistettävissä samantyyppisiin menestyksekkäihin tiimeihin. Käytännön työn kannalta transaktiivisen muistin kehittymiseen ilmeisesti kannat- taa panostaa vain monimutkaisissa tehtävissä. Työn teoreettinen kontribuutio on kontingenssihypoteesin tuominen transaktiivisen muistin teoriaan ja tapausevi- denssin lisäämistä teoriaan hajautettujen tiimien tapauksissa.

A transactive memory system consists of individu- als’ expertise, knowledge on “who knows what”, and communication between team members. It is proposed that an R&D team will perform successfully, if simple tasks are matched with less developed transactive memory system whereas complex tasks are matched with more developed transactive memory system. Qualitative research design is followed. Three research questions are asked: (1) How does a transactive memory system in a distributed R&D team look like?, (2) How is a transactive memory system in a distributed R&D team connected to its communication pattern (frequency of communication between team mem- bers)?, and (3) Is a developed transactive memory system a necessary attribute of a successfully performing R&D team with a simple task? Two distributed software development teams were studied. In both cases transac- tive memory systems were geographically localized: team members knew better peers from the same geographical location than those in distant offices. Commu- nication was also geographically localized; communication patterns and expertise recognition were correlated. The answer to the third question was positive. The findings are generalizable to the similar type of distributed R&D teams. Practical implications include that special attention to transactive memory system development should be paid only when team tasks are complex. From a theoreti- cal point of view, the study extends the theory of transactive memory by introduc- ing a contingency factor and bringing qualitative evidence on transactive memory systems in distributed organizational settings. Keywords distributed teams; information-processing; transactive memory; R&D perform- ance; case study; contingency theory VII Acknowledgements This work would not be possible without help of several people. First and fore- most I would like to express my sincere gratitude to my supervisor, Professor Tauno Kekäle, for his guidance and support. Tauno, thank you for being patient during all these years when I bombarded you with different questions. Your ad- vice was invaluable when my spirit was low and I doubted my abilities to proceed with the research. I would also like to thank Professor Petri Helo who four years ago offered me a position of project researcher. Without that my arrival to Finland and this dissertation had not be possible. My special thanks go to Professor Josu Takala who created at the Department of Production a perfect environment for researchers. International colleagues, freedom to make own decisions, evaluation of work on a basis of achievements rather than on hours spent in the office – all that I enjoyed a lot. It would be no exaggeration to say that the Department of Production is the best place I have worked so far. I would also like to thank Evald and Hilda Nissi Foundation which found my re- search topic interesting and administered to me several research grants. That funding allowed me to concentrate fully on my work. Project tasks I fulfilled in between research grants left some time for continuing the study. Petri Helo, thank you for that. My gratitude also goes to the University of Vaasa and the Foundation of the Uni- versity of Vaasa which funded my trips to scientific conferences in various pla- ces. Those trips gave me unique chance to get to know different places of the world and meet researchers with similar interests. I would also like to thank two company representatives who kindly granted me access to their project and helped me with data collection. For the purposes of keeping anonymity I do not mention your names here but I would like you to know that I highly value your positive and open attitude towards me as a re- searcher. My special thanks are directed to the reviewers of this thesis: Professor Petra de Weerd-Nederhof from the University of Twente (the Netherlands) and Professor Marko Torkkeli from the Lappeenranta University of Technology (Finland). Your feedback and comments helped me to improve the quality of this manuscript. I would also like to thank Professor Petra de Weerd-Nederhof for her commitment in acting as an opponent in the public defense of the thesis. VIII During my stay here I have met many people who helped me to adjust to a new culture, both local and those who came here from other countries. Thank you for being friends. Without you my life here would have been extremely boring. In a bit unusual way I would also like to mention those instances when I expected support but did not get it. I am glad that not everything went smoothly during my stay here because “what did not kill me made me stronger”. Now I can cope with problems better than when I came here. Finally, my deepest gratitude goes to my mother who understood my thirst for knowledge and adventure and was not against me going abroad. I understand that for you staying alone in the home country was nearly the same as for me going alone to a foreign one. Thank you for your courage, optimism, love, and support.

J. Ellis Matthew J. Pearsall, University of Arizona and Michael S. Christian University of North Carolina This study examines how teams respond to unplanned member loss. We draw on theory of team compilation and adaptation to suggest that teams with well-developed trans- active memory systems (TMS) will be better equipped to withstand the loss of a member. Then, based on role criticality theories, we argue that those effects depend on which member is absent, such that when a more critical member is lost, the perfor- mance benefits of a TMS are reduced. Finally, we reason that this interactive effect is because of the team’s ability to engage in plan formulation. We tested and found support for our hypotheses using 78 four-member teams engaged in a command-and- control simulation. TMS positively affected team performance following the loss of a member, but the benefits of the TMS were reduced following the loss of a critical member because teams had more difficulty engaging in plan formulation. We discuss how the results of this study add to our understanding of the precursors of successful team adaptation. Keywords: team adaptation, transactive memory, critical team member Team-based organizations often operate in thieu, 2000; Waller, 1999). In organizations, dynamic environments where survival depends teams must adapt to a wide-ranging set of cir- on the ability to successfully adapt to changing cumstances, including external contingencies circumstances (Kozlowski, Gully, Nason, & such as communication equipment failures Smith, 1999).

    Available online at www.sciencedirect.com Cognitive Systems Research 9 (2008) 33–51 www.elsevier.com/locate/cogsys A conceptual and empirical framework for the social distribution of cognition: The case of memory Action editor: Leslie Marsh Amanda J. Barnier a,*, John Sutton b, Celia B. Harris a, Robert A. Wilson c a Macquarie Centre for Cognitive Science, Macquarie University, Sydney, NSW 2109, Australia b Department of Philosophy, Macquarie University, Sydney, NSW 2109, Australia c University of Alberta, Edmonton, Canada Received 4 April 2007; accepted 5 July 2007 Available online 15 August 2007 Abstract In this paper, we aim to show that the framework of embedded, distributed, or extended cognition offers new perspectives on social cognition by applying it to one specific domain: the psychology of memory. In making our case, first we specify some key social dimen- sions of cognitive distribution and some basic distinctions between memory cases, and then describe stronger and weaker versions of distributed remembering in the general distributed cognition framework. Next, we examine studies of social influences on memory in cognitive psychology, and identify the valuable concepts and methods to be extended and embedded in our framework; we focus in par- ticular on three related paradigms: transactive memory, collaborative recall, and social contagion. Finally, we sketch our own early stud- ies of individual and group memory developed within our framework of distributed cognition, on social contagion of autobiographical memories, collaborative flashbulb memories, and memories of high school at a high school reunion. We see two reciprocal benefits of this conceptual and empirical framework to social memory phenomena: that ideas about distributed cognition can be honed against and tested with the help of sophisticated methods in the social-cognitive psychology of memory; and conversely, that a range of social mem- ory phenomena that are as yet poorly understood can be approached afresh with theoretically motivated extensions of existing empirical paradigms.

  • Memory in Mind and Culture
    This page intentionally left blank Memory in Mind and Culture This text introduces students, scholars, and interested educated readers to the issues of human memory broadly considered, encompassing individual mem- ory, collective remembering by societies, and the construction of history. The book is organized around several major questions: How do memories construct our past? How do we build shared collective memories? How does memory shape history? This volume presents a special perspective, emphasizing the role of memory processes in the construction of self-identity, of shared cultural norms and concepts, and of historical awareness. Although the results are fairly new and the techniques suitably modern, the vision itself is of course related to the work of such precursors as Frederic Bartlett and Aleksandr Luria, who in very different ways represent the starting point of a serious psychology of human culture. Pascal Boyer is Henry Luce Professor of Individual and Collective Memory, departments of psychology and anthropology, at Washington University in St. Louis. He studied philosophy and anthropology at the universities of Paris and Cambridge, where he did his graduate work with Professor Jack Goody, on memory constraints on the transmission of oral literature. He has done anthro- pological fieldwork in Cameroon on the transmission of the Fang oral epics and on Fang traditional religion. Since then, he has worked mostly on the experi- mental study of cognitive capacities underlying cultural transmission. After teaching in Cambridge, San Diego, Lyon, and Santa Barbara, Boyer moved to his present position at the departments of anthropology and psychology at Washington University, St. Louis. James V.

Marsh , Suparna Rajaram a Duke University, United States b Stony Brook University, United States The internet is rapidly changing what information is available as well as how we find it and share it with others. Here we examine how this “digital expansion of the mind” changes cognition. We begin by identifying ten properties of the internet that likely affect cognition, roughly organized around internet content (e.g., the sheer amount of information available), internet usage (e.g., the requirement to search for information), and the people and communities who create and propagate content (e.g., people are connected in an unprecedented fashion). We use these properties to explain (or ask questions about) internet-related phenomena, such as habitual reliance on the internet, the propagation of misinformation, and consequences for autobiographical memory, among others. Our goal is to consider the impact of internet usage on many aspects of cognition, as people increasingly rely on the internet to seek, post, and share information. Keywords: Memory, Cognition, Internet, External memory, Metacognition, Social memory General Audience Summary The internet is rapidly changing what information is available to us as well as how we find that information and share it with others.

The goal of this article is to provide a systematic and integrative survey of their philosophical dimensions, including their metaphysical, epistemological, and ethical dimensions, drawing together debates across the humanities, cognitive sciences, and social sciences. Metaphysical dimensions of memory technologies include their function, the nature of their informational properties, ways of classifying them, and their ontological status. Epistemological dimensions include the truth-conduciveness of external memory, the conditions under which external memory counts as knowledge, and the metacognitive monitoring of external memory processes. Finally, ethical and normative dimensions include the desirability of the effects memory technologies have on biological memory, their effects on self and culture, and their moral status. While the focus in the article is largely philosophical and conceptual, empirical issues such as the way we interact with memory technologies in various contexts are also discussed. We thus take a naturalistic approach in which philosophical and empirical concepts and approaches are seen as continuous. Keywords Cognitive enhancement, extended knowledge, extended mind, external memory, function, information, metacognition, neuroethics Introduction Human biological memory systems are complex, multifaceted phenomena. Technologies that scaf- fold, aid, and transform biological memory are likewise complex and multifaceted.

Pereira-Pasarin2 1Department of Psychology, Stony Brook University, Stony Brook, NY, and 2 Department of Psychology, Caldwell College, Caldwell, NJ Abstract People often form and retrieve memories in the company of others. Yet, nearly 125 years of cognitive research on learning and memory has mainly focused on individuals working in isolation. Although important topics such as eyewitness memory and autobiographical memory have evaluated social influences, a study of group memory has progressed mainly within the provinces of history, anthropology, sociology, and social psychology. In this context, the recent surge in research on the cognitive basis of collaborative memory marks an important conceptual departure. As a first aim, we review these empirical and theoretical advances on the nature and influence of collaborative memory. Effects of collaboration are counterintuitive because individuals remember less when recalling in groups. Collaboration can also lead to forgetting and increase memory errors. Conversely, collaboration can also improve memory under proper conditions. As a second aim, we propose an overarching theoretical framework that specifies the cognitive mechanisms associated with the costs and benefits of collaboration on memory. A study of the reciprocal influences of the group and the individual on memory processes naturally draws upon several disciplines. Our aim is to elucidate the cognitive components of this complex phenomenon and situate this analysis within a broader interdisciplinary perspective. Keywords collaborative memory, retrieval disruption, reexposure benefits, error pruning, social contagion errors, blocking and forgetting, collective memory People often form and retrieve memories in the company of psychology, and anthropology (e.g., Halbwachs, 1950/1980; others.

    iS CHANNEL Rational, Interpretivist, and Practical Approaches to Organizational Memory Dmitrijs Kravcenko PhD Candidate in Innovation, Knowledge, and Organizational Networks Research Centre (IKON) Warwick Business School The University of Warwick KEYWORDS ABSTRACT Organizational Memory To study organizations means to study their memories. At different points in time, organizational memory has been considered in the literature as a time-capsule, Practice Theory a social system that attributes meaning, and a teleological aspect of a practice. Building on these theories this essay will attempt to present a holistic overview of the mnemonic phenomenon. A proposed distinction between short- and long-term manifestations of practice memory and the role of organizational memory in solidifying regimes of practices within an organization is discussed. Possible questions for further research are put forward. Introduction that I will consider into two broad categories. These categories attempt to group theories together based Organizational memory is a feature that contextualizes on their common ontological and epistemological and communicates an organization both internally orientations towards the rationality of organizational and externally. It is difficult, if not impossible, to memory, i.e. the collective orientation to the efficient understand an organization without looking at accomplishment of functional collective goals (Scott, where it came from and how it got to where it is. 1987). Ontological assumptions concern such areas as Furthermore,
