Bridging Act-R And Project Malmo, Developing Models Of Behavior In Complex Environments, David M. Schwartz
Bridging Act-R And Project Malmo, Developing Models Of Behavior In Complex Environments, David M. Schwartz
Honors Theses
Cognitive architectures such as ACT-R provide a system for simulating the mind and human behavior. On their own they model decision making of an isolated agent. However, applying a cognitive architecture to a complex environment yields more interesting results about how people make decisions in more realistic scenarios. Furthermore, cognitive architectures enable researchers to study human behavior in dangerous tasks which cannot be tested because they would harm participants. Nonetheless, these architectures aren’t commonly applied to such environments as they don’t come with one. It is left to the researcher to develop a task environment for their model. The difficulty …

Working memory is the fundamental component of cognition that allows us to temporarily maintain information needed for concurrent processing. An existing theory from the literature, the time-based resource-sharing (TBRS) model, posits that working memory is a serial, rapidly switching, attentional refreshing mechanism. While others have sought previously to formalize the TBRS model into a computational process model, I go further, using ACT-R to model the influence of working memory on an entire task from end to end. I leverage ACT-R's existing base-level learning mechanism, typically used to model recency and frequency effects in long-term memory, to enact the attentional refreshing …

The Use Of Prior Knowledge In Learning From Examples, Stephen B. Blessing '89
Doctoral Dissertations
This dissertation examines the way people acquire procedures from examples, and provides a computational model of the results. In four experiments, people learned an analog of algebra. For each experiment, the initial know ledge that people had of the task was varied. In two experiments (Experiments 1 and 3), the syntactic know ledge that people had concerning the task w as manipulated. The knowledge of syntax that participants had, particularly the ability to correctly parse the character string, was found to be a major determiner in the way participants acquired the rules. Experiment 2 explicitly manipulated participant's awareness as to …
