Gestalt principles in Human Planning Behavior

Positioning. The article, submitted to the Cognitive Science Conference 2013, investigates the influence of visual patterns on the planning process.

Method. Psychological experiment; eye tracking study; and formal analysis

Results. The findings indicate the influence of the so-called distracting clusters on the human reasoning process. These clusters can be explained by Gestalt effects.

Cognitive Robotics and Navigation

Positioning. The article, published at the International Conference on Cognitive Modeling 2012, presents a cognitive ACT-R agent controlling a simple robot by the cognitive architecture ACT-R.

Research Question. Can we replicate human behavior in a navigation task by implementing ACT-R on a Lego MindStorm Robot?

Method. Cognitive Modeling

Results. The cognitive robotic system (Lego MindStorm Robot) shows a similar behavior to humans while navigating in a labyrinth. Especially the construction of a pseudo mental map (based on chunks) shows that many limitations of humans depend on the restriction of the working memory.
