URL: From grayw at rpi.edu Thu May 8 08:50:15 2003 From: grayw at rpi.edu (Wayne Gray) Date: Thu, 8 May 2003 08:50:15 -0400 Subject: [ACT-R-users] dissertations available on line Message-ID: Greetings. I am pleased to announce that three fairly recent to very recent dissertations are now available for downloading from my website. The abstracts can be read at: Wai-Tat Fu http://www.rpi.edu/~grayw/pubs/papers/WFu2003_diss.html Michael J. Schoelles http://www.rpi.edu/~grayw/pubs/papers/Schoelles02_diss.html Brian D. Ehret http://www.rpi.edu/~grayw/pubs/papers/Ehret99_diss.html All entail a substantial ACT-R modeling effort of dynamic environments. All include empirical test of the models. Wai Tat's is the most recent and arguably entails the most complete exploration of ACT-R's conflict resolution mechanism (PG-C, learning P, learning C, credit assignment issues) that has been done to date. One ACTR model with the same parameters (with one very reasonable exception) predicts the data from three experiments. Michael Schoelles' entails one actr model of a complex dynamic task that was applied to four different interface conditions in two different experiments. This is arguably the largest and most dynamic ACTR 5 model to date. Brian Ehret's shows that the normal ACTR mechanisms when used in a visual search task suffice to acquire location information. A very clever experimental paradigm and modeling effort. Wayne -- **Rensselaer**Rensselaer**Rensselaer**Rensselaer**Rensselaer** Wayne D.

Ritter) Date: Fri, 16 May 2003 11:38:28 -0400 Subject: [ACT-R-users] masters thesis, with code on the web on testing telephones Message-ID: Similar to Wayne's email, here's a master's thesis that has just come out of the lab: Freed, A. R. (2003). The effects of interface design on telephone dialing performance (Tech. Report No. 2003-1). Applied Cognitive Science Lab, School of Information Sciences and Technology, Penn State. http://acs.ist.psu.edu/acs-lab/reports/freed03.pdf. Abstract: We look at several prototype telephone interfaces with a variety of tools for automatic testing. Several analyses are presented. The first analysis uses Fitts' Law to determine the minimum possible usage time. Fitts' Law provided a quick analysis of the telephones but did not consider any factors other than target sizes and distances. The second analysis uses a cognitive model to make predictions about other factors such as visual search. The model used an organized search strategy that produced similar behavior to the experiment subjects but failed for a few extreme interfaces. Although the model dialing time predictions are too high, we propose that this model is worth paying attention to because the dialing time orderings among phones and number of fixations closely follows the observed data. The third analysis uses a human experiment to test the predictions with reaction times and eye-tracking data. The experiment subjects were able to easily cope with these differences and retain an organized strategy, but the model was forced to revert to a random search strategy. The users often made errors while using interfaces but the cognitive model did not make the same types of errors. Our approach should be generalizable to other types of interfaces, including VCRs, software applications, and webpages. Our analysis techniques can eventually remove the need for expensive and time-consuming user testing, which may be replaced with analytical and cognitive model analysis.

The architecture notably incorporates the distinction between implicit and explicit processes. The work described in the book demonstrates the cognitive validity of the architecture, by ways of capturing a wide range of human learning data. Computational properties of the architecture is explored with experiments that manipulate implicit and explicit processes to optimize performance in a range of domains. Philosophical implications of the approach, on situated cognition, intentionality, symbol grounding, and consciousness, are also explored in detail. In a nutshell, this book motivates and develops a framework for studying human cognition, based on an approach that is characterized by its focus on the dichotomy of, and the interaction between, implicit and explicit cognition. -------------------------------------------------------------------- For more details, go to http://www.cecs.missouri.edu/~rsun/book6-ann.html To order the book, go to https://www.erlbaum.com/shop/tek9.asp?pg=products&specific=0-8058-3880-5 =================================================================== Professor Ron Sun, Ph.D James C.

Soar 20th Anniversary Workshop Invitation to attend the 23rd Soar Workshop, June 23-27, 2003, Ann Arbor Michigan. It has been a little more than twenty years since the first version of Soar turned over. Since that time, Soar has been used world wide for developing AI systems, building cognitive models, controlling robots, and controlling characters in computer games. To celebrate, we are trying to make this year' s workshop even more special than usual. We are expanding the technical portion of Soar workshop to three days (June 25-27), broadening the scope of presentations and discussions, inviting many people from outside the traditional Soar community to attend, and even giving out Soar T-shirts! If you are new to Soar, the workshop is a great way to learn Soar (we have tutorials June 23-24), come up to speed on current research on Soar, and meet other Soar researchers who are potential collaborators. If you are old to Soar, now is a great time to see old friends, get up to speed on new developments, and participate in defining its future (see below). We want to also invite people working in other architectures. You will learn more about Soar and we will learn more about research outside of Soar. We invite you to give a talk on your own work in another architecture - just make sure you relate it to Soar in some way. One of the goals of the workshop is to plan out the future of Soar, specifically to increase its use and usability. What can we do so more people use Soar and Soar is easier to learn and use? We will set aside one afternoon for brainstorming on the problems and possible solutions. Everything is on the table for discussion from the structure and implementation of Soar, to interface and development tools, to the way we organize the community. There are some resources potentially available to help us with this, so this is not just an exercise. Please come! Soar workshops have always been intellectually exciting, bringing together research in AI, cognitive science, HCI, and cognitive modeling from both academic and industrial perspectives. To find out more and register, go to the workshop web site: http://ai.eecs.umich.edu/~soar/workshop23.html Please forward this invitation to other relevant mailing lists.

Techniques for modeling human and organizational behaviour in synthetic environments: A supplementary review. Wright-Patterson Air Force Base, OH: Human Systems Information Analysis Center. Ordering information (including information about the downloadable PDF file) is available at : http://iac.dtic.mil/hsiac/SOARS.htm Abstract: We summarize selected recent developments and promising directions for improving the quality of models of human performance in synthetic environments. The potential uses and goals for behavioral models in synthetic environments are first summarized. We focus on the topics of providing more complete performance, on providing better integration of the models with synthetic environments and with each other (reusability), and improved usability of the models, an important but neglected aspect of their performance. Within this context, we review relevant, current work related to modeling. For example, we examine cognitive modeling of emotion, advanced techniques for testing and building models of behavior, new cognitive architectures including hybrid architectures, and agent and Belief, Desires and Intentions (BDI) architectures. A list of projects with high payoff for modeling human performance in synthetic environments is provided as a conclusion. ********************************************************************* 8. The Australian Cog Sci Fest (Australasian Society for Cognitive Science, ASCS, http://www.cogsci.unsw.edu.au) is international this year. One of the interesting symposia is Cognitive Issues in the Design and Predictive Operation of Systems-of-Systems Applications. http://www.arts.unsw.edu.au/cogsci2003/conf_content/prop_symosia.html Deadlines are past for papers, but for an invitation to attend without paper, send an email to Simon Goss (Simon.Goss at dsto.defence.gov.au). Background A new class of problems have emerged from the ability to network socio-technical systems both within and across organisational boundaries. A fundamental feature of these large, distributed, complex systems is our current inability to perform predictions on their long-term behaviour. Example application areas include: the stock market, de-regulated electricity markets (such as in California where electricity providers have been bankrupted in a single day due to a lack of understanding of options trading), network-centric warfare (the military is moving away from aggregating functions on a single platform to distributing functions across platforms and coordinating their activities in some manner), interplanetary manned space missions (where the flight controllers and scientists on Earth have a 40 minute communication delay when talking with the astronauts on Mars), and the internet (at the application level). The characteristics of this new class of problems include: for design, analysis and predictive operation for the new class of problems, and the implications for the wider cognitive science community (is it more of the same or are there some underlying assumptions that need to be challenged?). More generally, we want to establish a network of researchers working on the new class of problems, identify approaches being used in the problem space, and provide a forum for identifying research challenges to the wider cognitive science community. Related Work There is a lot of related work that may be relevant to the new class of problems: -- The cognitive science community has raised the issues of situated action and distributed cognition. The ethnographic community has examined similar issues under the rubric of work practice studies and communities of practice. -- The systems thinking community has studied cognition at three levels of analysis: reacting to events, long-term patterns of behaviour, systemic structures and their limitations as diagnosed by system archetypes. We are interested in constructs at the systemic structures and patterns of behaviour level of analysis. -- There is considerable work under the rubric of linfrastructuren that examines the impact of new technologies and public policies eg transportation, housing, information instruments. What is the relationship of new infrastructures to our concept of cognition? -- The military have coined the term lsystems-of-systemsn and explored architectural approaches for examining the new class of problems. What insights do the systems-of-systems approach provide to cognitive science and what does cognitive science add to the systems-of-systems approach to the new class of problems? -- Research in artificial intelligence and cognitive science often takes a descriptive, textual approach. An alternative approach is by exploiting the power of imagery and the changes in the images over a period of time to understand a systemms pattern of behaviour. What is the underlying cognitive science constructs of an imagery approach, and how do these constructs help the design, analysis and predictive operation of the new class of problems? The Form of the Workshop Target audience: multi-disciplinary, researchers and practitioners who are interested in the cognitive science implications of the new class of problems. We aim to conduct a one day working workshop with a maximum of 15 participants. Participants will be selected on the basis of a position paper (maximum 10 pages). Position papers will be circulated to all participants before the workshop, along with an email discussion of important issues. The workshop will aim to identify approaches, assumptions and cognitive science constructs to aid the design, analysis, and predictive operation of the new class of problems. The position papers will be selected on the basis of their originality, relevance, and ability to stimulate discussion. We particularly encourage position papers from graduate students. The organisers intend to publish the outcome of this workshop in the refereed archival literature.
