In this report, we describe a computer-based training tutor, the D2P/Moving Target Tutor (MTT) and our experience and results of running an experimental study using undergraduate students (N=27) to evaluate the effectiveness of D2P/MTT. D2P/MTT is designed and created to train users to judge point of aim quickly to shoot a moving target. The structure of(More)
This paper examines the relationships between environmental and cognitive factors as they influenced the formation of social networks through modeling how these factors affect tie formation between pairs of agents in a simulated world. We modeled worlds consisting of 20, 40, and 60 ACT-R agents and examined the influence of population size, run time, map(More)
We examine how several environmental factors influence cog-nition and the emergence of social networks in artificial societies. Using a large-scale socio-cognitive simulation (VIPER), we generated social networks consisting of 20, 40, and 60 agents. We tested the impact that environmental factors such as population size, map configuration, and run time,(More)
We investigate how cognitive capacity limits the number of group relations that a person can maintain. The simulation experiment's results using ACT-R and its memory equations replicated an effect similar to that of Dunbar's (1998) number, or the average total number of group ties capable of being supported in memory. In our study, we also examined the(More)
This paper examines dyadic social tie formation, and how cognitive and environmental factors influence the formation of dyadic ties. Using agent models instantiated in ACT-R that interact in a large-scale social simulation, we capture the affect of environmental factors including population size, running time, and map configurations, as well as memory(More)
