Research: brief description

Søren Kyllingsbæk is Professor in Cognitive Psychology at the Department of Psychology and at the Department of Computer Science, University of Copenhagen. His research is mainly focused on experimental studies and mathematical modeling of visual cognition including visual perception, attention, and short-term memory as well as intentional actions. Together with Professors Claus Bundesen and Thomas Habekost, he has developed a Neural Theory of Visual Attention (NTVA; Bundesen, Habekost, & Kyllingsbæk, 2005), which forms the main basis of the empirical and theoretical work at the Center for Visual Cognition. Søren Kyllingsbæk’s recent work on NTVA has mainly been focusing on further theoretical extensions of NTVA to form a unified theory of perception, attention, and visual short-term memory, which he presented in a doctoral thesis in 2014 (see Kyllingsbæk, 2014). The work is done in collaboration with Professor Susanne Ditlevesen and Associate Professor Bo Markussen at the Department of Mathemathical Sciences, UCPH and Professor Barry Giesbrecht at the UCSB.

In collaboration with Associate Professor Thor Grünbaum from the Department of Media, Cognition and Communication, University of Copenhagen, Søren Kyllingsbæk studies human voluntary action more specifically intentional object-oriented action. The aim is to develop a mathematical theory of selections of intentions and intentional actions integrating philosophically and psychological approaches including psychophysical experiments and computational modeling.

Current research

Intention, Selection, and Agency

How do people remember what they have decided to do? How are those intentions stored and later, when the time is right, retrieved? This ability is central to human agency. Without it, we could not form intentions for future actions, we would lose our ability for long-term planning, and our psychological and practical life would lose its structure and stability. And yet, the problem of how intentions are selected and retrieved from memory has received little attention in the philosophical and psychological literature. This project will propose a new psychological model for the selection and retrieval of intentions from memory and situate it within existing philosophical debates.

The project runs within the CoInAct research group in collaboration with Thor Grünbaum from the Department of Media, Cognition and Communication and Mark Schram Christensen at the Department of Psychology.
