APEX: An Architecture for Modeling Human Performance in Applied HCI Domains

Full day tutorial
4th Floor, Appleton Tower, Crichton Street

This tutorial introduces participants to APEX, a tool for creating computer simulations of human performance in complex, dynamic environments. APEX is unique in its focus on identifying flaws in procedures and interfaces, and in its use of an "automated cognitive walkthrough" methodology for generating predictions of behavior. In particular, it is intended as a practical means for predicting opportunities for human error in interactive applied domains. So far, the system has been applied to air traffic control, commercial jet cockpits, and consumer devices such as automated teller machines. APEX is designed to be an easy-to-use and easy-to-teach tool for modeling behavior and cognition in tasks ranging from ATM to ATC.

 

Michael Freed is a Research Scientist at NASA Ames Research Center and is the developer of the APEX architecture. He holds a Ph.D. in Computer Science from Northwestern University.

Michael Matessa is a Research Psychologist at NASA Ames Research Center. He holds a Ph.D. in Cognitive Psychology from Carnegie Mellon University.

Alonso Vera is a Research Scientist at NASA Ames Research Center. He holds a Ph.D. in Cognitive Psychology from Cornell University. Prior to his position at NASA, he taught at The University of Hong Kong.

An Introduction to the COGENT Cognitive Modelling Environment (with special emphasis on applications in computational linguistics)

Half day tutorial (afternoon)

COGENT is a graphical environment for cognitive modelling. It provides domain-general facilities for developing, running and evaluating computational models based on a box and arrow notation. The system allows users to 1) sketch the functional components of their model; 2) flesh out the sketch by specifying the computational properties of boxes or writing production-like rules; and 3) explore the behaviour of the resulting model through "computational experiments". COGENT is currently being used for both cognitive modelling teaching and research in several institutions and an introductory cognitive modelling text using the environment is in preparation.

This half-day tutorial will introduce attendees to the COGENT environment through the hands-on development and exploration of a number of models of the parsing process (including bottom-up and left-corner models, and parallel and serial models). On completing the tutorial attendees will have a working knowledge of COGENT and its strengths and weaknesses, both in the domain of computational linguistics and in cognitive modelling more generally. The tutorial will be aimed primarily at those with minimal computational experience, but extensive tutorial materials will ensure that the session is also suitable for attendees with backgrounds in computational linguistics and/or cognitive modelling.

This tutorial will give an overview of eye-tracking methodology, with a focus on eye tracking as a method to investigate reading processes. We start with an introduction into the main topics in eye movement research and discuss the main characteristics of eye movements. We then go on to discuss the various eye-tracking systems and their advantages and disadvantages. We will also compare eye tracking with other methodologies. Finally, a large part of the tutorial will consist of practical comments about how to run eye-tracking studies and how to analyse the data. We will consider how fixations and saccades can be determined, and discuss different eye-tracking measures.

ACT-R 5.0

Half-day tutorial (morning)
Call Centre HCRC, enter via 2 Buccleuch Place

John R. Anderson

Pittsburgh, PA 15213

ACT-R is a cognitive theory and simulation system for developing cognitive models. It assumes cognition emerges through the interaction of a procedural memory of productions with a declarative memory of chunks. The ACT-R 4.0 version of the theory was detailed in the book "The Atomic Components of Thought" by John R. Anderson and Christian Lebiere, published in 1998 by Lawrence Erlbaum Associates. Since its release in 1997, ACT-R 4.0 has supported the development of over 75 cognitive models, published in the literature by as many different researchers. These models cover topics as diverse as driving behavior, implicit memory, learning backgammon, metaphor processing, and emotion. We have recently developed a new version, ACT-R 5.0 that extends the ACT-R 4.0 to be more interruptible, to achieve greater across-task parameter consistency, to have better mechanisms of production learning, and to be more in correspondence with our knowledge of brain function. While the new system extends the capabilities of ACT-R 4.0 it involves relatively few changes and is actually simpler. This short tutorial will provide an overview of ACT-R, as it is specified in the 5.0 version. It will not assume a prior background in ACT-R 4.0.

John Anderson received his B.A. from the University of British Columbia in 1968 and his Ph.D. from Stanford University 1972. He has been at Carnegie Mellon University since 1978 where he is a professor of psychology and computer science. He is a member of the American National Academy of Science. He has published a number of books including Human Associative Memory (1973 with Gordon Bower), Language, Memory, and Thought (1976), The Architecture of Cognition (1983), The Adaptive Character of Thought (1990), Rules of the Mind (1993) and Atomic Components of Thought (1998 with Christian Lebiere). His current research is involved with three enterprises involved in the testing various aspects of the ACT-R theory of cognitive architecture. One is to model the acquisition of cognitive skills, particularly those involving dynamic problem solving. The second is application of the architectures to developing intelligent tutoring systems and cognitive agents for training. The third is research on brain imaging to identify the neural correlates of the cognitive architecture.

How to Deal with Modularity in Formal Language Theory: An Introduction to Grammar Systems, Grammar Ecosystems and Colonies

Full day tutorial [cancelled]

Carlos Martin-Vide
Professor of Linguistics
Head of the Research Group on Mathematical Linguistics
Rovira i Virgili University
cmv@astor.urv.es, cmv@tinet.fut.es


The tutorial is intended to present a quick picture of three new areas of (nonstandard) formal language theory that are essentially based on modular postulates and could have some relevance for cognitive science formalizations.

In order to contextualize the topics, first we'll introduce the very basics of standard formal language theory (languages, Chomsky hierarchy, automata hierarchy,...), and then we'll move quickly into the following nonstandard mechanisms:

  1. cooperating distributed grammar systems (CD) [1 hour]
  2. hybrid cooperating distributed grammar systems (HCD) [1 hour]
  3. parallel communicating grammar systems (PC) [1 hour]
  4. parallel communicating grammar systems with teams (PCT) [1 hour]
  5. grammar ecosystems [1 hour]
  6. colonies [1 hour]

Regarding them, we intend to provide the audience with a vademecum of methods and results. The tutorial will also include a few exercises to be solved in the classroom.

Generally speaking, the aim of the tutorial is to provide people attending it with some discrete mathematical tools able to simulate modular phenomena. It doesn't require any special mathematical background. Only interest and motivation for mathematical thinking is expected.

Carlos Martin-Vide is Professor of Linguistics and Head of the Research Group on Mathematical Linguistics at Rovira i Virgili University (Tarragona, Spain). He is coauthor of more than 160 papers in mathematical linguistics and formal language theory published in international journals and conference proceedings. As well, he edited several volumes, among others: Current Issues in Mathematical Linguistics (North-Holland, Amsterdam, 1994), Mathematical and Computational Analysis of Natural Language (John Benjamins, Amsterdam, 1998), Issues in Mathematical Linguistics (John Benjamins, Amsterdam, 1999), Where Mathematics, Computer Science, Linguistics and Biology Meet (Kluwer, Dordrecht, 2001, with V. Mitrana), and Grammars and Automata for String Processing: From Mathematics and Computer Science to Biology, and Back (Gordon and Breach, London, 2001, with V. Mitrana). His work in the last five years has been mainly concentrated on contextual grammars, grammar systems and DNA computing. He is founder and editor-in-chief of the journal Grammars (Kluwer, Dordrecht).
