My research interests revolve around neurocognitive interactions between eye movements, visual attention, memory systems and mental imagery. To investigate such topics I mainly use eye-tracking methodology.
In previous research I have together with my colleagues from LUCS mental imagery group demonstrated that persons who look at a blank screen while recalling a visual scene from memory spontaneously look as if the imagined scene is still in front of them.
Remarkably, it also appears that such eye movements to “nothing” are not merely a fascinating epiphenomenon but indeed play an active role in the internal simulations which constitute episodic remembering and depending on how and where people launch their eye movements their formation and scanning of visual episodes can either get facilitated or impaired.
Currently I am heading the researcher project "Recollections seen from the viewpoint of different minds", which is funded by the Swedsih Research Council. This project aims to in detail investigate how individuals’ gaze behavior interacts with the encoding and retrieval of their episodic memories. This questions if tightly linked to my work in the project Culture, Brain and Learning funded by the Knut and Alice Wallenberg Foundation where our research focus is on neurocognitive aspects of narrative processing and learning.
Current key questions of my research:
- How are gaze patterns established during encoding and retrieval predictive of retrieval performance?
- How does this relationship interact with individual differences in cognitive capabilities, styles and strategies?
- How do visual attention and gaze behavior interact with the selection and inhibition of episodic memories?
- How do visual attention and gaze behavior relate to different spatio-temporal context cues during episodic memory retrieval?
- How can pupillometry inform us about selective memory retreival?
Apart from my main research I am also active in projects where we use eye-tracking to investigate how visual feedback from an emerging text influences writers’ text production.
All projects are part of the Linneaus environment Thinking in Time: Cognition, Communication and Learning (CCL).
