How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Chapter
Knowledge graphs and ontologies represent information in a variety of different applications. One use case, the Intelligence, Surveillance, & Reconnaissance: Mutli-Attribute Task Battery (ISR-MATB), comes from Cognitive Science, where researchers use interdisciplinary methods to understand the mind and cognition. The ISR-MATB is a set of tasks that...
Chapter
Workload management is integral to the success of human-machine teams, and involves measuring and predicting workload and implementing proactive interventions to mitigate the adverse effects of degraded performance. Common approaches to workload measurement rely on the use of subjective, behavioral, and physiological metrics. These approaches suffe...

Training negotiation is difficult because it is a complex, dynamic activity that involves multiple parties. It is often not clear how to create situations in which students can practice negotiation or how to measure students' progress. Some have begun to address these issues by creating artificial software agents with which students can train. Thes...
Conference Paper
Full-text available
We developed a cognitive-pharmacokinetic computational (CPC) model to understand how pharmacoactive substances, such as caffeine and toluene, modulate cognition. In this integrated model, dynamic physiological mechanisms are simulated to predict concentrations of the solvent toluene in the brain, which modulates specific cognitive systems in a dose...
Article
The Metalogue project aims to develop a multi-modal, multi-party, dialogue system with metacognitive abilities that will advance our understanding of natural conversational human-machine interaction, and interfaces that incorporate multimodality into virtual and augmented reality environments. In this paper we describe the envisaged technical syste...
Conference Paper
Full-text available
The paper describes experimental dialogue data collection activities, as well semantically annotated corpus creation undertaken within EU-funded METALOGUE project. The project aims to develop a dialogue system with flexible dialogue management to enable systems adaptive, reactive, interactive and proactive dialogue behaviour in setting goals, choos...
Article
Full-text available
Many studies have examined how people recall the locations of objects in spatial layouts. However, little is known about how people monitor the accuracy of judgments based on those memories. The goal of the present experiments was to examine the effect of reference frame characteristics on metacognitive accuracy for spatial judgments. Reference fra...
Article
In this article, we examine the advantages of simple metacognitive capabilities in a repeated social dilemma. Two types of metacognitive agent were developed and compared with a non-metacognitive agent and two fixed-strategy agents. The first type of metacognitive agent (opponent perspective) takes the perspective of the opponent to anticipate the...

a.stevens@rug.nl), Niels A. Taatgen (n.a.taatgen@rug.nl), Fokie Cnossen (f.cnossen@rug.nl) Abstract In this paper, we show ACT-R agents capable of metacognitive reasoning about opponents in the repeated prisoner's dilemma. Two types of metacognitive agent were developed and compared to a non-metacognitive agent and two fixed-strategy agents. The fi...
Article
The use of peer assessment to evaluate students’ writing is one recommended method that makes writing assignments possible in large content classes (i.e., more than 75 students). However, many instructors and students worry about whether students of all ability levels are capable of helping their peers. We examine how ability pairing (e.g., high-ab...
