Adaptive Control of Thought – Rational (ACT-R) Cognitive Architecture

A Computational Investigation of Sources of Variability in Sentence Comprehension Difficulty in Aphasia

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 161-174 Abstract “We present a computational evaluation of three hypotheses about sources of deficit in sentence comprehension in aphasia: slowed processing, intermittent deficiency, and resource reduction. The ACT‐R based Lewis and Vasishth (2005) model is used to implement these three proposals. Slowed processing is implemented as […]

Building an ACT‐R Reader for Eye‐Tracking Corpus Data

Topics in Cognitive Science

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 144-160 Abstract “Cognitive architectures have often been applied to data from individual experiments. In this paper, I develop an ACT‐R reader that can model a much larger set of data, eye‐tracking corpus data. It is shown that the resulting model has a good fit to the

Computational cognitive modeling of the temporal dynamics of fatigue from sleep loss

Psychonomic Bulletin & Review

Published in: Psychonomic Bulletin & Review, Volume 24, Issue 6, December 2017, 1785-1807 Abstract “Computational models have become common tools in psychology. They provide quantitative instantiations of theories that seek to explain the functioning of the human mind. In this paper, we focus on identifying deep theoretical similarities between two very different models. Both models are
