To realize human-like robot intelligence, a large-scale cognitive architecture is required for robots to understand the environment through a variety of sensors with which they are equipped. In this paper, we propose a novel framework named Serket that enables the construction of a large-scale generative model and its inference easily by connecting sub-modules to allow the robots to acquire var...

We have been creating an authoring tool, the Cognitive Model SDK, which allows non-cognitive scientists and non-programmers to produce a cognitive model for model-tracing tutors [1, 2]. The SDK is in use by developers at Carnegie Learning to produce their commercial Cognitive Tutors for math. However, it has never been evaluated with regards to the strong claim that noncognitive scientists and ...

Modeling crowd behaviors is an important challenge for intelligent virtual agents. We propose a general cognitive model of simulating crowd behaviors, based on Festinger’s Social Comparison Theory (SCT), a prominent social psychology theory. We present the use of the SCT model (using the Soar cognitive architecture) in the generation of imitational behavior in loosely-coupled groups and show th...

aggregation operators (aos) have been studied by many schol- ars. as many aos are proposed, there is still lacking approach to classify the categories of ao, and to select the appropriate ao within the ao candidates. in this research, each ao can be regarded as a cognitive style or individual dierence. a cognitive style and aggregation operator (csao) model is pro- posed to analyze the mapping ...

Within the general objective of conceiving a cognitive architecture for image interpretation able to generate outputs relevant to several target user profiles, the paper elaborates on a set of operations that should be provided by a cognitive space to guarantee the generation of relevant descriptions. First, it attempts to define a working definition of contrast operation. Then, revisiting well...

This paper describes a cognitive modeling effort for the O’Hare Modernization Project (OMP). Beginning with a statement of the problem, it describes how cognitive modeling was used to measure the mental workload and work time of controllers running various positions at O’Hare International Airport, both under the current airport configurations and a future set of configurations (proposed in the...

While computational cognitive modeling has made great strides in addressing complex dynamic tasks, the modeling of individual differences in complex tasks remains a largely unexplored area of research. In this paper we present a straightforward approach to modeling individual differences, specifically age-related cognitive differences, in complex tasks, and illustrate the application of this ap...

This special issue of Cognitive Systems Research presents a collection of remarkable papers on cognitive modeling based on communications delivered at ICCM-2006, the Seventh International Conference on Cognitive Modeling (Fum, Del Missier, & Stocco, 2006) held in Trieste, Italy, from April 5th to 8th, 2006. Being the organizers and chairmen of the conference, we have been invited to serve as gu...

This paper presents an implementation of a cognitive model of a complex real-world task in the cognitive architecture Soar. During the implementation process there were lessons learned on various aspects, such as the retrieval of working memory elements with relative values, alternative approaches to reasoning, and reasoning control. Additionally, the implementation is compared to an earlier im...
