ACT-R Based Models For Learning Interactive Layouts
… presents research on learning of interactive layouts. I develop two models based on a theory of cognition known as ACT-R (Adaptive Control of Thought–Rational). I validate them against experimental data collected by other researchers. The first model is a simulation model that emulates …

Comparing vector-based and ACT-R memory models using large-scale datasets: User-customized hashtag and tag prediction on Twitter and StackOverflow
… accurately they predict a user’s chosen tags: an ACT-R based Bayesian model and a random permutation vector-based model. Millions of posts and tweets were collected, and both declarative memory models were used to predict Twitter hashtags and StackOverflow tags. The results show that past user …

Experimental user interface design toolkit for interaction research (IDTR).
… 1, the Adaptive Control of Thought Rational (ACT-R) cognitive architecture is used to design Simulated Users (SU) models. This allows models of user interaction to be tested on a specific User Interface (UI). In phase 2, an evolutionary algorithm is added and used to evolve and test an …

An investigation into the cognitive effects of instructional interface visualisations.
… research have focussed on the best practices for training and learning delivered via computer based multimedia simulations. More often than not, the aim has been cost minimisation through an optimisation of the instructional delivery process for efficient knowledge acquisition. The …

A Computational Model of Jetliner Taxiing
… simulations. In this thesis, I present an ACT-R cognitive model to emulate pilot taxiing behavior in a dynamic environment, in order to predict human behavior in novel situations imposed by NextGen constraints. The model is validated by comparing taxi routes generated by the model to routes …

A computational model of routine procedural memory
… The CSM is a hierarchically organized network of action schemas and goals. Botvinick and Plaut (2004) instead took a connectionist approach to modeling routine procedural behavior. They argued in favor of holistic, distributed representation of learned step co-occurrence associations. Two …

Modélisation informatique des erreurs de nature cognitive impliquées lors de la réalisation d'activités de la vie quotidienne
… qui perturbent, entre autres, la réalisation des activités de la vie quotidienne. Suite à l'évolution des technologies, il est maintenant possible d'offrir une aide au travers d'habitats intelligents. Pour que l'aide soit appropriée, on peut souhaiter tout d'abord comprendre et modéliser les …

"What does ""it"" mean anyway? Examining the time course of semantic activation in reference resolution"
… a pronoun leads the comprehender to reactivate the semantics of its antecedent. We examined this hypothesis by manipulating the concreteness of a noun antecedent and assessing whether an Event Related Potential (ERP) concreteness effect was elicited at a downstream pronoun. We observed …

Cognitive modelling of attentional networks: efficiencies, interactions, impairments and development
… that measures the efficiencies and interactions of these three subcomponents of attention in a single task, and has been used for adults, children and attention deficit patients. In this thesis, cognitive modelling is used as a research tool to simulate the performance of subjects on the …

Working memory and prediction in human sentence parsing
… to processing difficulty as compared to syntactic prediction. Within the last decades, evidence for a content-addressable memory system underlying human cognition in general has accumulated (e.g., Anderson et al., 2004). In sentence processing research, it has been proposed that this general …

Toward an integrated model of sentence processing in reading
… these measures are the result of an interaction of multiple cognitive levels and processing strategies and thus are only indirect indicators of processing difficulty. In order to properly interpret an eye movement response, one has to understand the underlying principles of adaptive …
