„Immersive Memory: Natural Usage and Spatial Frames 

How we use working and long-term memory as we move through our environment remains poorly understood, since most laboratory tasks remove visual material while participants remain still and do not offer alternatives to relying on memory representations. In a series of virtual reality (VR) studies, we investigated the usage and properties of memory when reliance on memory emerges as a natural consequence of interactions with the environment. In the first part of the talk, I will present studies which characterize the spatial frames in which information is held and selected in working memory following self-movement in immersive environments. In the second part, I will talk about studies investigating a fundamental psychological function that is central to many of our interactions in the environment: “sensorimnemonic decisions” – when to rely on memories versus sampling sensory information anew to guide behaviour.

„The internal dynamics that drive behaviour”

Behaviour emerges from a complex interaction between two dynamic systems: the brain and the environment. Specifically, to act efficiently and adaptively, our brain must integrate shifting goals and cognitive states, with dynamic sensory inputs. These interactions continuously shape how we perceive and act in the world. Here, in a series of experiments, we investigate how these complex dynamics drive various aspects of behaviour. In the first part of the talk, I will present findings which show how oscillatory internal states can have downstream effects on perception and action selection. Next, I will demonstrate how our attentional and motor system rapidly adapt to changing task demands. Finally, I will highlight the flexible nature of our cognitive system by showing how our internal representations can adapt to external temporal regularities.
