      and distributed cognition in practices

Introduction
     Halverson (2002) asks: “What does CSCW1 need to DO with theories?” in her
study. In order to answer the question, she first claims that CSCW has adopted and
even mixed many different theories, conceptual frameworks, and methods for
different purpose. And then she chooses two theories: activity theory and distributed
cognition theory which are frequently used in CSCW studies and closely examines
them with four requisite of a successful theory. Unfortunately, she concludes that
although theoretical strength of both theories could direct researchers’ focus and
benefit their analysis and communication, neither one will satisfy all needs of CSCW
because the complexity of each theory’s conceptual framework, difficult to apply,
and the lack of prediction power. Yet the status of theoretical “grab bag” in CSCW
cannot be overcome with either activity theory or distributed cognition theory. My
study is inspired by this conclusion.

    Although my empirical study intend to continue Halverson’s research, I will
neither derive nor invent any new theory, and nor will I promote or against any
particular theory.    Instead, my research interest is to discover the recent
movement of activity theory and distributed cognition theory in practice in CSCW. I
anticipate an ecological picture about how these two theories are used in CSCW will
be drawn by describing a deeper practical understanding of the similarities,
differences, and relationships among them.


Literature Review
Cognition in the wild
     CSCW moves the study of HCI from a focus on individual user’s desktop toward
multiuser environment, which requires a close examination of work and the context
that such work is performed within. (Perry, 2003) The study of such systems is part of
a new multidisciplinary field (C. A. ElliS, S.J. GibbS, and G.L. Rein, 1991), and,

  Using terms such as “computer- supported cooperative work (CSCW)” and “groupware,” these systems perform functions such
as helping people collaborate on writing the same document, managing projects, keeping track of tasks, and finding, sorting, and
prioritizing electronic messages. Other systems in this category help people display and manipulate information more effectively
in face-to-face meetings and represent and share the rationales for group decisions. (THOMAS W. MALONE, & KEVIN
CROWSTON, 1994)

                                                                                                                              1

according to Rogers (2004), it is a “turn to the social”. Sociologists, anthropologists
and others in the social sciences came into HCI while bringing new frameworks,
theories and ideas about technology use and system design.

     Meanwhile, a new and hybrid approach of cognitive theory was developed by
Edwin Hutchins and his colleagues (Roger, 1997). This approach stresses the
cognition “in the wild” instead of “in the mind”. Hutchins claims that cognition is
better understood as a distributed phenomenon compared to the traditional view of
cognition and is best explained in terms of information processing at the individual
level (Roger, 1997). To Hutchins, a human cognitive process is the process in which
our everyday cultural practices are enacted. Culture is not any collection of things,
but it is rather an adaptive process that accumulates partial solutions to frequently
encountered problems (Hutchins, 1995). Similarly, activity theory in its original Soviet
context was used to explain cultural practices (e.g. work, school) in the
developmental, cultural and historical context in which they occur (Roger, 2004).

    Both activity theory and distributed cognition theory are named as “post-
cognitivist” theory because “they have been brought into interaction design (HCI) to
remedy perceived shortcomings of cognitivist theory” (Victor Kaptelinin, & Bonnie A.
Nardi, 2006). Moreover, Halverson (2002) claims two theories’ similarities are:
emphasize cognition; include the social and cultural context of cognition; and share a
commitment to ethnographically collected data. Although these two theories share
some significant commonness, they also diverge in critical ways (Victor Kaptelinin, &
Bonnie A. Nardi, 2006). In the following section, I will give a summarized introduction
of these two theories in order to provide a better distinct understanding of them.

Distributed cognition theory
    Distributed cognition theory dissolves the traditional divisions between the
inside and outside boundary of the individuals, and focuses on the interactions
between the distributed structures of the phenomena (Rogers, 1997). Moreover,
the symmetry between humans and nonhumans is evident characteristic of
distributed cognition theory. In this point of view, both humans and nonhumans
can be components carrying out various processes in the system, and both can be
media in which representational states are created or through which they are
propagated (Eric P.S. Baumer, Bill Tomlinson, 2011).

    According to Nardi’s (1996) study, Distributed cognition asserts as a unit of
analysis on a cognitive system composed of individuals and the artifacts they use.
Therefore, one of the main outcomes of the distributed cognition approach is an
explication of the complex interdependencies between people and artifacts in their


                                                                                      2

work activities (Rogers, 2004). In other words, in distribution cognition theory,
process(ing) is so central to the analysis that it may be less obvious to the uninitiated.
Unlike activity theory there is no clear structure applied to each situation. Instead, it
is built into the process of analysis, and may or may not be represented in the
products of that analysis (Halverson, 2002). This approach of theoretical framework
makes distributed cognition theory’s power lies in its flexible unit of analysis (Rogers,
1997; Halverson, 2002). Researchers can adopt different units of analysis, to describe
a range of cognitive systems, whereby some subsume others (Hutchins, 1995).

Activity theory
     Activity theory focuses on the interaction between human activities and
consciousness within its relevant environmental context. Human activities are driven
by certain needs (objectives). Therefore, in activity theory, human activity is the base
unit of analysis. The relationship between subjects and objects of activity is mediated
by a tool. Continuous construction is going on between the components of an
activity system. Humans not only use tools, they also continuously renew and
develop them either consciously or unconsciously. (Uden, L., Valderas, P & Pastor, O.,
2008).

     There are different interpretations of activity theory and different facets to it (e.g.
development of personality, structure of consciousness, and hierarchical structure of
activity) (Mathew, 2010). The most cited application of activity theory is Engestrøm’s
(1990) activity system model (Rogers, 2004), which includes a community, social
rules, and division of labour in the analytic framework. Rogers (2004) claims that the
main role of this approach is analytic, a set of interconnected concepts which provide
by activity theory that can be used to identify and explore interesting problems in
field data.

    Activity theory is a broadly applied theory in CSCW (Halverson, 2002), some
researchers use it for meta-level analyses, some develop models to extend the
theory or to define new phenomena, and some use it to assist the design. Many
researchers adopt activity theory because of its adaptability, Rogers (2008) describes
the advantage of a customized activity theory framework is that it can be mapped
more easily and obviously onto the problem domain, and enabling the researcher or
designer to explicitly identify problems and solutions. Because activity theory gives
a relatively specific structure into which observations are fit, it tends to led to higher
level of analysis while distributed cognition theory led to a lower level of analysis,
focusing on the ways that individual actions change the state of the cognitive system
(Eric P.S. Baumer, Bill Tomlinson, 2011).

Methodology
     This empirical study presents and discusses findings from a review of recent
publications (published after 2007) related to two postcogintivist theories: activity
theory and distributed cognition in practice. The publications take account of these
                                                   resources: research journals,

                                                      research issues related to this
                  Created by Kraut, 2003
                                                      topic (Kraut, 2003). There are
three dimensions in this conceptual map, and an overall introduction is given at next
paragraph.

    According to Kraut (2003), CSCW researchers differ in their approaches because
of their different backgrounds and disciplines. Some researchers who “build” systems
to support small group work are typically from the computer science or engineering.
Others focus on empirical “study” such as describing a social phenomenon or
identifying causal relation and influential factors; and these researchers are usually
from the social science disciplines of psychology, sociology, and anthropology.
Therefore, their studies often describe how applications were used and the
consequences of their use. Group size and focus are the other two dimensions. In the
dimension of focus, from top to bottom are five different topics:” infrastructures,
architectures, application, task, and people”. The first two usually related to system
or software building, and they are more engineering oriented. On the contrary,
researchers from social science disciplines are more likely focus on topics like “people”
and ”task”. Meanwhile, concern of “application” is a more neutral topic. Kraut
(2003) claims that the typical size or scope of the social collective treated in most
CSCW researches is “small groups” or “teams” of members between three and a
dozen people. However, based on Kraut’s study, the scope of group can range from


                                                                                      4
Ru-ping Kuo, 2012/3/13
“dyads” to “organizations”, communities and the “society”.

      Kraut’s conceptual map provides a throughout and integrated view of CSCW
research and practice; I adopt it as my study and analysis framework to help me
analysis and categorize the finding. By reviewing with the systematical framework,
this empirical study could discover patterns from all publications and possibly
illustrate the ecology of these two theories in practice.


Finding
    The publications’ select and review process is conducted in following steps:
    1. First, review all publications that meet my key words requirements; screen
        and withhold repeated and unrelated articles. A total of 25 articles are
        sustained after this step.
    2. Secondly, look over every article and identify each paper’s approach, focus,
          and group size based on the definition of the research framework.
          Through this analysis and coding process, I discover that a research paper
          may study a phenomenon and then use the finding to improve or create a
          design. Similarly, a study could have more than one focus and several types
          of subject. Thus, I choose to count the frequency and compute the ratio
          to portray my finding in discussion section.
    3.    Moreover, a “selected coding” process is used in my study, too. 25
          publications are coded and categorized with three additional labels:
          application field, creation or output, study and data collect methods which
          are not defined in the research framework but related to my research goals.

    And Table 1 (pp. 6-7) is the summary of my finding.

Researchers who have sociology background conduct more CSCW studies with
distributed cognition theory than researchers who have computer science or
engineering background. However, the difference is smaller for studies using
activity theory. And overall, there are more CSCW research papers using activity
theory than distributed cognition theory between 2007 and today, especially after
year 2011.

     As I describe in methodology section, Kraut’s conceptual map of CSCW is used
as a research framework in my study. Table 3 gives a clear picture of how are these
two theories used in practice. Activity theory has been applied to a wide variety of
settings in HCI research and design (Eric P.S. Baumer, Bill Tomlinson, 2011). My study
result supports this assumption. Compared to distributed cognition theory, activity
theory applied to all topics and all scope of groups. In addition, about 88% of
distributed cognition studies concentrate on either individuals or small groups. And
they also focus on topics like people and task mostly. 40% of activity theory studies
focus on organization.

     Although researchers with computer science and engineering background tend
to focus their studies on topics like infrastructure, architecture, and application
(Kraut, 2003), my finding shows differently (e.g. Syavash Nobarany, Mona Haraty, &
Brian Fisher, 2012; Jeffrey Guenther, Fred Volk, & Mark Shaneck, 2010; Uden, L.,
Valderas, P & Pastor, O., 2008)


                                                                                                  8
Ru-ping Kuo, 2012/3/13
Application
    The purpose of CSCW is to build tools that will help groups of people do their
work more efficiently. Therefore, one important goal of CSCW researches is to
develop technology that would allow distributed teams to work as if they were
collocated (Kraut, 2003). Based on my analysis, large amount of researches agree
that either activity theory or distributed cognition theory could bring advantages to
CSCW related design as well as evaluation. And as Table 1 shows, there are very
board applications for these two theories. They are included but not limited to the
following.
     1. Education and training, from creating personal learning environment (e.g.
          Ilona Buchem, Graham Attwell, &Ricardo Torres, 2011), collaborative
          learning application (e.g. Ahmed Kharrufa, David Leat, & Patrick Olivier,
          2010), to Google effect on learning (e.g. Michael Yacci, & Evelyn P. Rozanski,
          2012).
     2.   Medical, hospital, and research lab. For example, activity-based
          computing(e.g. Jakob Bardram, & Afsaneh Doryab, 2011), emergency
          services (e.t. Mishra, J. L., Allen, D. K., & Pearman,A. D., 2011), daily
          technology practices in the lab (e.g. Ellie Harmon, & Nancy J. Nersessian,
          2008).
     3.   Group works, virtual teams, and management. For example, decision
          making system (e.g. Nallini Selvaraj, Bob Fields, & Paola, Amaldi-Trillo,
          2007), network security analysis (e.g. Jeffrey Guenther, Fred Volk, & Mark
          Shaneck, 2010), and knowledge management system (e.g. Ray
          Kekwaletswe, & Thuli Bobela, 2011).
     4.   Web development, such as web application requirement gathering (e.g.
          Uden, L., Valderas, P., & Pastor, O., 2008), and FAQ and message board
           design (e.g. Sherlock, 2007)

Creation & outputs
      According to Kraut’s conceptual map, there are two approaches of CSCW
researches: “build” and “study”. My study discovers that these two approaches are
not necessarily isolated. Butler, Esposito, & Herbon (1999) describe the two
objectives of analysis: to understand the current situation and to produce
requirements for improvement. I also notice that these two objectives sometime are
sequent or interactive with each other when I review the publications.
Furthermore, by applying either one of these two poscognitivist theories in studies,
researchers can gain valuable insights or create various outputs. The benefits range
from abstract concepts to concrete prototypes or products. For example, conceptual
frameworks (e.g. BR Belland, 2011; Terence Blackburn, Paul Swatman,& Rudi Vernik,

                                                                                      9
Ru-ping Kuo, 2012/3/13
2007), analysis frameworks (e.g. Roger Haigh Mills, 2011; Mishra, J. L., Allen, D. K., &
Pearman, A. D., 2011; James D. Hollan & Edwin L. Hutchins, 2009), practical
frameworks (e.g. Ashok, A., & Beck, C., 2007), models (e.g. Nallini Selvaraj, Bob Fields,
& Paola Amaldi-Trillo, 2007), and design guidelines (e.g. Jakob Bardram, & Afsaneh
Doryab, 2011; Ahmed Kharrufa, David Leat, & Patrick Olivier, 2010) or heuristics (e.g.
Pooya Jaferian, et.al., 2011).

     Generally speaking, if we just Table 4 ratio of two approaches based on the creations
compare creations (outputs) among                             Build             Study
these publications, researchers use       Dcog                8     67%          4     33%

more than to “study something”.
And the Table 4 shows the ratios of two theories are both about 70% to 30%.

Data collection and analysis methods
      Although anthropography is a significant approach to both activity theory and
distributed cognition theory in practice, there are multiple research methods used
among these 25 publications (show as table 5). Some of the studies collect both
qualitative and quantitative data (e.g. Michael Yacci, & Evelyn P. Rozanski, 2012;
Syavash Nobarany, Mona Haraty, & Brian Fisher, 2012; Benbunan-Fich, R., Adler, R. &
Mavlanova, T., 2011) no matter which theory is used in the studies. There are
totally 5 papers collecting both quantitative and qualitative data compared to the
other 20 papers which are only collected qualitative data. However, there is not
any study relying on quantitative data only.

Ru-ping Kuo, 2012/3/13
apply distributed cognition theory. Three three most frequently used methods
among these 25 publications are case study, observation, and interview.

Motivations behind the theory in practice
     Every researcher justify why they use one theory over another. Therefore, I will
summarize the motivations which I learned from the 25 publications. I also believe
that we can gain some insights of the practical issues of theories chosen by
comparing these reasons to two theories’ advantages or disadvantages.

     Why distributed cognition theory?
     1. Inspiration of belief, anthropology approach, or related studies’ successful
        experiences (e.g. Nallini Selvaraj, Bob Fields, & Paola Amaldi-Trillo, 2007;
        Michael Yacci, Evelyn P. Rozanski, 2012; Ellie Harmon, Nancy J. Nersessian,
        2008; James D. Hollan, Edwin L. Hutchins, 2009 )
     2. “A mind in the world”. The need to analyze working environments and
          describe cognitive processes spreading among mutual interactions of
          humans and artifacts over time (e.g. Michael Yacci, Evelyn P. Rozanski, 2012;
          Syavash Nobarany, Mona Haraty, Brian Fisher, 2012; Zachary O. Toups,
          Andruid Kerne, William A. Hamilton, Nabeel Shahzad, 2011; Terence
          Blackburn, Paul Swatman and Rudi Vernik, 2007; Ellie Harmon, Nancy J.
          Nersessian, 2008)
     3.   Contextual oriented, task relevant information is stored in multiple forms:
          mental models, embedded in the environment (including culture), and
          derived via formulae (e.g. Zachary O. Toups, Andruid Kerne, William A.
          Hamilton, Nabeel Shahzad, 2011; Mills, 2011)
     4.   Team cognition gets distributed across individuals, artifacts, and the setting.
          It is used to design a system that can help users reduce cognitive effort
          needed. (e.g. Aleksandra Sarcevic, Ivan Marsic, Michael E. Lesk, Randall S.
          Burd, 2008)
     5.   Provide situated support for human activities analysis framework (e.g. Ellie
          Harmon, Nancy J. Nersessian, 2008; Terence Blackburn, Paul Swatman and
          Rudi Vernik, 2007)

     Why activity theory?
     1. Activity Theory is a descriptive and analysis tool, and it provides a
          framework of six interrelated components: subject, object, tools, rules,
          community and division of labor. (e.g. Ilona Buchem, Graham Attwell, &
          Ricardo Torres, 2011; Mishra, J. L., Allen, D. K., & Pearman, A. D., 2011;
          Jeffrey Guenther, Fred Volk, & Mark Shaneck, 2010)
     2.   Activity Theory is a theoretical framework which can be used to study,

                                                                                      11
Ru-ping Kuo, 2012/3/13
analyze, describe, and understand or predict human activity, including
          collaborative activities and the use of technology (e.g. Jakob Bardram, &
          Afsaneh Doryab, 2011; Uden, L., Valderas, P & Pastor, O., 2008; Jakob
          Bardram, & Afsaneh Doryab, 2011; Ashok, A., & Beck, C., 2007; Laha, 2011)
     3.   Activity theory focus on activities and goals rather than digital artifacts
          (Ashok, A., & Beck, C., 2007)
     4.   Activity theory provides a broad theoretical framework for describing the
          structure, development and context of human activities (e.g. Uden, L.,
          Valderas, P & Pastor, O., 2008; Uden, L., Valderas, P & Pastor, O., 2008;
          Ashok, A., & Beck, C., 2007; Laha, 2011; Sherlock, 2007)


Summary
     Conforming to my anticipation, by carefully review and analysis 25 publications
with Kraut‘s (2003) conceptual map, I portray an ecological picture of these two
postcognitivist theories in practice. My empirical findings also vary some attributes of
Kraut’s model. For example, in the approach dimension, “build” and “study” are not
necessary exclusive, moreover, the relationship between researchers’ disciplines and
the research focus are not as clear and absolute as Kraut’s suggestion.

    However, the differences between activity theory and distributed cognition
theory in practice are perceptible from prior discussion. Baumer, & Tomlinson (2011)
claims that “The choice of evaluation methodology – if any – must arise from and be
appropriate for the actual problem or research question under consideration”.
Although it seems that activity theory can adopted in broader setting, such as topics
of focus, type of group size, and the research and data collect methods, my study
cannot provide true explanations about it. Regarding the vantages of the two
theories, motivations that proposed by these 25 studies’ researchers reflect the
promise of the two theories. The diversity of activity theory and distributed
cognition theory’s theoretical framework are also distinct from the findings of these
publications. For example, just like Rogers suggest (2008), most of papers that
using activity theory will create their own research or analysis frameworks based on
modifications on Engestrøm’s (1990) activity system model.

     At last, because of the research time and resource limitation, my study only
review publications published between 2007 and 2012 which can be found in ACM
digital library with two set of key words “CSCW” and “activity theory” or “CSCW” and
“distributed cognition theory”. Therefore, I believe that the pattern of these two
theories in practice will be more fertile and clear if the research scope and timeframe
can be expanded.

                                                                                     12

The ecology of two theories: activity theory and distributed cognition in practice

  • 1. The ecology of two theories: activity theory and distributed cognition in practices HCDE 501 | Ru-ping Kuo Introduction Halverson (2002) asks: “What does CSCW1 need to DO with theories?” in her study. In order to answer the question, she first claims that CSCW has adopted and even mixed many different theories, conceptual frameworks, and methods for different purpose. And then she chooses two theories: activity theory and distributed cognition theory which are frequently used in CSCW studies and closely examines them with four requisite of a successful theory. Unfortunately, she concludes that although theoretical strength of both theories could direct researchers’ focus and benefit their analysis and communication, neither one will satisfy all needs of CSCW because the complexity of each theory’s conceptual framework, difficult to apply, and the lack of prediction power. Yet the status of theoretical “grab bag” in CSCW cannot be overcome with either activity theory or distributed cognition theory. My study is inspired by this conclusion. Although my empirical study intend to continue Halverson’s research, I will neither derive nor invent any new theory, and nor will I promote or against any particular theory. Instead, my research interest is to discover the recent movement of activity theory and distributed cognition theory in practice in CSCW. I anticipate an ecological picture about how these two theories are used in CSCW will be drawn by describing a deeper practical understanding of the similarities, differences, and relationships among them. Literature Review Cognition in the wild CSCW moves the study of HCI from a focus on individual user’s desktop toward multiuser environment, which requires a close examination of work and the context that such work is performed within. (Perry, 2003) The study of such systems is part of a new multidisciplinary field (C. A. ElliS, S.J. GibbS, and G.L. Rein, 1991), and, 1 Using terms such as “computer- supported cooperative work (CSCW)” and “groupware,” these systems perform functions such as helping people collaborate on writing the same document, managing projects, keeping track of tasks, and finding, sorting, and prioritizing electronic messages. Other systems in this category help people display and manipulate information more effectively in face-to-face meetings and represent and share the rationales for group decisions. (THOMAS W. MALONE, & KEVIN CROWSTON, 1994) 1 Ru-ping Kuo, 2012/3/13
  • 2. according to Rogers (2004), it is a “turn to the social”. Sociologists, anthropologists and others in the social sciences came into HCI while bringing new frameworks, theories and ideas about technology use and system design. Meanwhile, a new and hybrid approach of cognitive theory was developed by Edwin Hutchins and his colleagues (Roger, 1997). This approach stresses the cognition “in the wild” instead of “in the mind”. Hutchins claims that cognition is better understood as a distributed phenomenon compared to the traditional view of cognition and is best explained in terms of information processing at the individual level (Roger, 1997). To Hutchins, a human cognitive process is the process in which our everyday cultural practices are enacted. Culture is not any collection of things, but it is rather an adaptive process that accumulates partial solutions to frequently encountered problems (Hutchins, 1995). Similarly, activity theory in its original Soviet context was used to explain cultural practices (e.g. work, school) in the developmental, cultural and historical context in which they occur (Roger, 2004). Both activity theory and distributed cognition theory are named as “post- cognitivist” theory because “they have been brought into interaction design (HCI) to remedy perceived shortcomings of cognitivist theory” (Victor Kaptelinin, & Bonnie A. Nardi, 2006). Moreover, Halverson (2002) claims two theories’ similarities are: emphasize cognition; include the social and cultural context of cognition; and share a commitment to ethnographically collected data. Although these two theories share some significant commonness, they also diverge in critical ways (Victor Kaptelinin, & Bonnie A. Nardi, 2006). In the following section, I will give a summarized introduction of these two theories in order to provide a better distinct understanding of them. Distributed cognition theory Distributed cognition theory dissolves the traditional divisions between the inside and outside boundary of the individuals, and focuses on the interactions between the distributed structures of the phenomena (Rogers, 1997). Moreover, the symmetry between humans and nonhumans is evident characteristic of distributed cognition theory. In this point of view, both humans and nonhumans can be components carrying out various processes in the system, and both can be media in which representational states are created or through which they are propagated (Eric P.S. Baumer, Bill Tomlinson, 2011). According to Nardi’s (1996) study, Distributed cognition asserts as a unit of analysis on a cognitive system composed of individuals and the artifacts they use. Therefore, one of the main outcomes of the distributed cognition approach is an explication of the complex interdependencies between people and artifacts in their 2 Ru-ping Kuo, 2012/3/13
  • 3. work activities (Rogers, 2004). In other words, in distribution cognition theory, process(ing) is so central to the analysis that it may be less obvious to the uninitiated. Unlike activity theory there is no clear structure applied to each situation. Instead, it is built into the process of analysis, and may or may not be represented in the products of that analysis (Halverson, 2002). This approach of theoretical framework makes distributed cognition theory’s power lies in its flexible unit of analysis (Rogers, 1997; Halverson, 2002). Researchers can adopt different units of analysis, to describe a range of cognitive systems, whereby some subsume others (Hutchins, 1995). Activity theory Activity theory focuses on the interaction between human activities and consciousness within its relevant environmental context. Human activities are driven by certain needs (objectives). Therefore, in activity theory, human activity is the base unit of analysis. The relationship between subjects and objects of activity is mediated by a tool. Continuous construction is going on between the components of an activity system. Humans not only use tools, they also continuously renew and develop them either consciously or unconsciously. (Uden, L., Valderas, P & Pastor, O., 2008). There are different interpretations of activity theory and different facets to it (e.g. development of personality, structure of consciousness, and hierarchical structure of activity) (Mathew, 2010). The most cited application of activity theory is Engestrøm’s (1990) activity system model (Rogers, 2004), which includes a community, social rules, and division of labour in the analytic framework. Rogers (2004) claims that the main role of this approach is analytic, a set of interconnected concepts which provide by activity theory that can be used to identify and explore interesting problems in field data. Activity theory is a broadly applied theory in CSCW (Halverson, 2002), some researchers use it for meta-level analyses, some develop models to extend the theory or to define new phenomena, and some use it to assist the design. Many researchers adopt activity theory because of its adaptability, Rogers (2008) describes the advantage of a customized activity theory framework is that it can be mapped more easily and obviously onto the problem domain, and enabling the researcher or designer to explicitly identify problems and solutions. Because activity theory gives a relatively specific structure into which observations are fit, it tends to led to higher level of analysis while distributed cognition theory led to a lower level of analysis, focusing on the ways that individual actions change the state of the cognitive system (Eric P.S. Baumer, Bill Tomlinson, 2011). 3 Ru-ping Kuo, 2012/3/13
  • 4. Methodology This empirical study presents and discusses findings from a review of recent publications (published after 2007) related to two postcogintivist theories: activity theory and distributed cognition in practice. The publications take account of these resources: research journals, Approach conference and workshop proceedings and book sections. Based on my research goal, the selection of publications for the Focus review was search with the key words “CSCW” and “activity theory” or “CSCW” and “distributed cognition” from Group ACM digital library. CSCW is a subfield of human-computer interaction Figure 1 Research Framework (HCI). Figure1 shows a variety of (The conceptual map of CSCW research) research issues related to this Created by Kraut, 2003 topic (Kraut, 2003). There are three dimensions in this conceptual map, and an overall introduction is given at next paragraph. According to Kraut (2003), CSCW researchers differ in their approaches because of their different backgrounds and disciplines. Some researchers who “build” systems to support small group work are typically from the computer science or engineering. Others focus on empirical “study” such as describing a social phenomenon or identifying causal relation and influential factors; and these researchers are usually from the social science disciplines of psychology, sociology, and anthropology. Therefore, their studies often describe how applications were used and the consequences of their use. Group size and focus are the other two dimensions. In the dimension of focus, from top to bottom are five different topics:” infrastructures, architectures, application, task, and people”. The first two usually related to system or software building, and they are more engineering oriented. On the contrary, researchers from social science disciplines are more likely focus on topics like “people” and ”task”. Meanwhile, concern of “application” is a more neutral topic. Kraut (2003) claims that the typical size or scope of the social collective treated in most CSCW researches is “small groups” or “teams” of members between three and a dozen people. However, based on Kraut’s study, the scope of group can range from 4 Ru-ping Kuo, 2012/3/13
  • 5. “dyads” to “organizations”, communities and the “society”. Kraut’s conceptual map provides a throughout and integrated view of CSCW research and practice; I adopt it as my study and analysis framework to help me analysis and categorize the finding. By reviewing with the systematical framework, this empirical study could discover patterns from all publications and possibly illustrate the ecology of these two theories in practice. Finding The publications’ select and review process is conducted in following steps: 1. First, review all publications that meet my key words requirements; screen and withhold repeated and unrelated articles. A total of 25 articles are sustained after this step. 2. Secondly, look over every article and identify each paper’s approach, focus, and group size based on the definition of the research framework. Through this analysis and coding process, I discover that a research paper may study a phenomenon and then use the finding to improve or create a design. Similarly, a study could have more than one focus and several types of subject. Thus, I choose to count the frequency and compute the ratio to portray my finding in discussion section. 3. Moreover, a “selected coding” process is used in my study, too. 25 publications are coded and categorized with three additional labels: application field, creation or output, study and data collect methods which are not defined in the research framework but related to my research goals. And Table 1 (pp. 6-7) is the summary of my finding. Discussion Overview As show in table 1, 25 publications are selected in this empirical study. Table 2 is the summary of every year’s number of publications based on researchers’ background.

  • 8. Researchers who have sociology background conduct more CSCW studies with distributed cognition theory than researchers who have computer science or engineering background. However, the difference is smaller for studies using activity theory. And overall, there are more CSCW research papers using activity theory than distributed cognition theory between 2007 and today, especially after year 2011. As I describe in methodology section, Kraut’s conceptual map of CSCW is used as a research framework in my study. Table 3 gives a clear picture of how are these two theories used in practice. Activity theory has been applied to a wide variety of settings in HCI research and design (Eric P.S. Baumer, Bill Tomlinson, 2011). My study result supports this assumption. Compared to distributed cognition theory, activity theory applied to all topics and all scope of groups. In addition, about 88% of distributed cognition studies concentrate on either individuals or small groups. And they also focus on topics like people and task mostly. 40% of activity theory studies focus on organization. Table 3 the summary of two theories in practice (based on research framework) Distributed Cognition Activity Theory study 46.2% 47.1% Approach build 53.8% 52.9% Infrastructure 0.0% 2.9% Architecture 0.0% 14.7% Engineering/ application 7.4% 14.7% Focus Social / application 18.5% 23.5% Task 37.0% 23.5% people 37.0% 20.6% Individual 41.2% 28.0% dyad 0.0% 8.0% Group size Small group/team 47.1% 16.0% organization 11.8% 40.0% society 0.0% 8.0% Although researchers with computer science and engineering background tend to focus their studies on topics like infrastructure, architecture, and application (Kraut, 2003), my finding shows differently (e.g. Syavash Nobarany, Mona Haraty, & Brian Fisher, 2012; Jeffrey Guenther, Fred Volk, & Mark Shaneck, 2010; Uden, L., Valderas, P & Pastor, O., 2008) 8 Ru-ping Kuo, 2012/3/13
  • 9. Application The purpose of CSCW is to build tools that will help groups of people do their work more efficiently. Therefore, one important goal of CSCW researches is to develop technology that would allow distributed teams to work as if they were collocated (Kraut, 2003). Based on my analysis, large amount of researches agree that either activity theory or distributed cognition theory could bring advantages to CSCW related design as well as evaluation. And as Table 1 shows, there are very board applications for these two theories. They are included but not limited to the following. 1. Education and training, from creating personal learning environment (e.g. Ilona Buchem, Graham Attwell, &Ricardo Torres, 2011), collaborative learning application (e.g. Ahmed Kharrufa, David Leat, & Patrick Olivier, 2010), to Google effect on learning (e.g. Michael Yacci, & Evelyn P. Rozanski, 2012). 2. Medical, hospital, and research lab. For example, activity-based computing(e.g. Jakob Bardram, & Afsaneh Doryab, 2011), emergency services (e.t. Mishra, J. L., Allen, D. K., & Pearman,A. D., 2011), daily technology practices in the lab (e.g. Ellie Harmon, & Nancy J. Nersessian, 2008). 3. Group works, virtual teams, and management. For example, decision making system (e.g. Nallini Selvaraj, Bob Fields, & Paola, Amaldi-Trillo, 2007), network security analysis (e.g. Jeffrey Guenther, Fred Volk, & Mark Shaneck, 2010), and knowledge management system (e.g. Ray Kekwaletswe, & Thuli Bobela, 2011). 4. Web development, such as web application requirement gathering (e.g. Uden, L., Valderas, P., & Pastor, O., 2008), and FAQ and message board design (e.g. Sherlock, 2007) Creation & outputs According to Kraut’s conceptual map, there are two approaches of CSCW researches: “build” and “study”. My study discovers that these two approaches are not necessarily isolated. Butler, Esposito, & Herbon (1999) describe the two objectives of analysis: to understand the current situation and to produce requirements for improvement. I also notice that these two objectives sometime are sequent or interactive with each other when I review the publications. Furthermore, by applying either one of these two poscognitivist theories in studies, researchers can gain valuable insights or create various outputs. The benefits range from abstract concepts to concrete prototypes or products. For example, conceptual frameworks (e.g. BR Belland, 2011; Terence Blackburn, Paul Swatman,& Rudi Vernik, 9 Ru-ping Kuo, 2012/3/13
  • 10. 2007), analysis frameworks (e.g. Roger Haigh Mills, 2011; Mishra, J. L., Allen, D. K., & Pearman, A. D., 2011; James D. Hollan & Edwin L. Hutchins, 2009), practical frameworks (e.g. Ashok, A., & Beck, C., 2007), models (e.g. Nallini Selvaraj, Bob Fields, & Paola Amaldi-Trillo, 2007), and design guidelines (e.g. Jakob Bardram, & Afsaneh Doryab, 2011; Ahmed Kharrufa, David Leat, & Patrick Olivier, 2010) or heuristics (e.g. Pooya Jaferian, et.al., 2011). Generally speaking, if we just Table 4 ratio of two approaches based on the creations compare creations (outputs) among Build Study these publications, researchers use Dcog 8 67% 4 33% both theories to “build something” AT 11 69% 5 31% more than to “study something”. And the Table 4 shows the ratios of two theories are both about 70% to 30%. Data collection and analysis methods Although anthropography is a significant approach to both activity theory and distributed cognition theory in practice, there are multiple research methods used among these 25 publications (show as table 5). Some of the studies collect both qualitative and quantitative data (e.g. Michael Yacci, & Evelyn P. Rozanski, 2012; Syavash Nobarany, Mona Haraty, & Brian Fisher, 2012; Benbunan-Fich, R., Adler, R. & Mavlanova, T., 2011) no matter which theory is used in the studies. There are totally 5 papers collecting both quantitative and qualitative data compared to the other 20 papers which are only collected qualitative data. However, there is not any study relying on quantitative data only.

In contrast with studies using activity theory, the experiment method is only used in the studies that 10 Ru-ping Kuo, 2012/3/13
  • 11. apply distributed cognition theory. Three three most frequently used methods among these 25 publications are case study, observation, and interview. Motivations behind the theory in practice Every researcher justify why they use one theory over another. Therefore, I will summarize the motivations which I learned from the 25 publications. I also believe that we can gain some insights of the practical issues of theories chosen by comparing these reasons to two theories’ advantages or disadvantages. Why distributed cognition theory? 1. Inspiration of belief, anthropology approach, or related studies’ successful experiences (e.g. Nallini Selvaraj, Bob Fields, & Paola Amaldi-Trillo, 2007; Michael Yacci, Evelyn P. Rozanski, 2012; Ellie Harmon, Nancy J. Nersessian, 2008; James D. Hollan, Edwin L. Hutchins, 2009 ) 2. “A mind in the world”. The need to analyze working environments and describe cognitive processes spreading among mutual interactions of humans and artifacts over time (e.g. Michael Yacci, Evelyn P. Rozanski, 2012; Syavash Nobarany, Mona Haraty, Brian Fisher, 2012; Zachary O. Toups, Andruid Kerne, William A. Hamilton, Nabeel Shahzad, 2011; Terence Blackburn, Paul Swatman and Rudi Vernik, 2007; Ellie Harmon, Nancy J. Nersessian, 2008) 3. Contextual oriented, task relevant information is stored in multiple forms: mental models, embedded in the environment (including culture), and derived via formulae (e.g. Zachary O. Toups, Andruid Kerne, William A. Hamilton, Nabeel Shahzad, 2011; Mills, 2011) 4. Team cognition gets distributed across individuals, artifacts, and the setting. It is used to design a system that can help users reduce cognitive effort needed. (e.g. Aleksandra Sarcevic, Ivan Marsic, Michael E. Lesk, Randall S. Burd, 2008) 5. Provide situated support for human activities analysis framework (e.g. Ellie Harmon, Nancy J. Nersessian, 2008; Terence Blackburn, Paul Swatman and Rudi Vernik, 2007) Why activity theory? 1. Activity Theory is a descriptive and analysis tool, and it provides a framework of six interrelated components: subject, object, tools, rules, community and division of labor. (e.g. Ilona Buchem, Graham Attwell, & Ricardo Torres, 2011; Mishra, J. L., Allen, D. K., & Pearman, A. D., 2011; Jeffrey Guenther, Fred Volk, & Mark Shaneck, 2010) 2. Activity Theory is a theoretical framework which can be used to study, 11 Ru-ping Kuo, 2012/3/13
  • 12. analyze, describe, and understand or predict human activity, including collaborative activities and the use of technology (e.g. Jakob Bardram, & Afsaneh Doryab, 2011; Uden, L., Valderas, P & Pastor, O., 2008; Jakob Bardram, & Afsaneh Doryab, 2011; Ashok, A., & Beck, C., 2007; Laha, 2011) 3. Activity theory focus on activities and goals rather than digital artifacts (Ashok, A., & Beck, C., 2007) 4. Activity theory provides a broad theoretical framework for describing the structure, development and context of human activities (e.g. Uden, L., Valderas, P & Pastor, O., 2008; Uden, L., Valderas, P & Pastor, O., 2008; Ashok, A., & Beck, C., 2007; Laha, 2011; Sherlock, 2007) Summary Conforming to my anticipation, by carefully review and analysis 25 publications with Kraut‘s (2003) conceptual map, I portray an ecological picture of these two postcognitivist theories in practice. My empirical findings also vary some attributes of Kraut’s model. For example, in the approach dimension, “build” and “study” are not necessary exclusive, moreover, the relationship between researchers’ disciplines and the research focus are not as clear and absolute as Kraut’s suggestion. However, the differences between activity theory and distributed cognition theory in practice are perceptible from prior discussion. Baumer, & Tomlinson (2011) claims that “The choice of evaluation methodology – if any – must arise from and be appropriate for the actual problem or research question under consideration”. Although it seems that activity theory can adopted in broader setting, such as topics of focus, type of group size, and the research and data collect methods, my study cannot provide true explanations about it. Regarding the vantages of the two theories, motivations that proposed by these 25 studies’ researchers reflect the promise of the two theories. The diversity of activity theory and distributed cognition theory’s theoretical framework are also distinct from the findings of these publications. For example, just like Rogers suggest (2008), most of papers that using activity theory will create their own research or analysis frameworks based on modifications on Engestrøm’s (1990) activity system model. At last, because of the research time and resource limitation, my study only review publications published between 2007 and 2012 which can be found in ACM digital library with two set of key words “CSCW” and “activity theory” or “CSCW” and “distributed cognition theory”. Therefore, I believe that the pattern of these two theories in practice will be more fertile and clear if the research scope and timeframe can be expanded. 12 Ru-ping Kuo, 2012/3/13
