Second, it is necessary to evaluate the effectiveness and efficiency of high-level cognitive modeling languages if they are to make a significant impact in either the cognitive or social sciences.
First, we believe such studies are necessary for achieving and demonstrating the theoretical rigor and repeatability promised by high-level representation languages. This comparison accomplishes several things. This study docks an ACT-R model created with Herbal to one created by hand. We present a docking study for Herbal, a high-level behavioral representation language based on the problem space computational model. This architecture has poten-tial applications to training simulations. This extended version of ACT-R allows a user to computationally realize theories involving cognition, physiology, and their interaction. A model of the startle response and its consequent effects on cognition and physiolo-gy is presented to demonstrate an example use of the new substrate. We present ACT-RΦ (ACT-R Phi), a connection of the physiology simulation system HumMod (Hester et al., 2011) and the cognitive architecture ACT-R (Anderson, 2007) using an newly created ACT-R module. To add physiology to a cognitive architecture, it should be represented as a separate module or substrate. autonomic responses to memory featuring particularly aversive stimuli). hunger and decision-making), and the effects of cognition on physiology (e.g. This connection should facilitate both the effects of physiology on cogni-tion (e.g. This case study provides an initial validation of the applicability and effectiveness of our method.Ĭonnecting a physiological model to a cognitive architecture presents an attractive option to better simulate a wide range of human behavior.
With an experiment on a small service-oriented website, we identified usability problems which were cross-validated by domain experts, and quantified usability improvement by the higher task success rate and lower time and effort for given tasks after suggested corrections were implemented.

A software tool was developed to automate a significant part of the activities involved. The deviation data produced from this comparison can help us discover usability issues and suggest corrective actions to improve usability. The comparison is performed via the mechanism of test oracle for checking results and identifying user navigation difficulties. The anticipated usage, including information about both the path and time required for user-oriented tasks, is captured by our Ideal User Interactive Path (IUIP) models constructed by cognitive experts based on their cognition of user behavior. The actual usage patterns can be extracted from Web server logs routinely recorded for operational websites by first processing the log data to identify users, user sessions, and user task-oriented transactions, and then applying an usage mining algorithm to discover patterns among actual usage paths. We present a new method to identify navigation related Web usability problems based on comparing actual and anticipated usage patterns.
Computer Science > Artificial Intelligence.We conclude by discussing its future, which we believe will include adding emotions and physiology, increasing usability, and the use of nongenerative models. After this, we briefly discuss tools for working with ACT‐R, and also note several major accomplishments that have been gained by working with ACT‐R in both basic and applied science, including summarizing some of the insights about human behavior. Based on this history, we then describe it as a theory of cognition that is realized as a computer program. We start by reviewing its history, which shapes its current form, contrasts and relates it to other architectures, and helps readers to anticipate where it is going. It is comprised of a set of programmable information processing mechanisms that can be used to predict and explain human behavior including cognition and interaction with the environment. ACT‐R is a hybrid cognitive architecture.
