Grasping, Reaching and Spatial Perception Experimental Research
The aim of our research is to understand how we use perceptual processes for action planning and control and how our actions are moderated by visual and cognitive factors. Our studies and experiments are designed to provide insights into the behavioural and neuronal bottlenecks of perception-action processing with the aim of understanding the complex interplay between the perceptual, cognitive, and motor processing systems. Currently, we are pursuing a number of projects that can broadly be summarised in three major research questions:
- How are our actions moderated by physical (obstacles, bio-mechanics) and cognitive (attention, memory) constraints?
- What is the interrelationship of action and perception processes and what does this tell us about the organization of the human visual cortex?
- Can we use human-object interactions as a non-verbal indicator for human perception of material and surface properties?
To answer these questions, we primarily apply experimental behavioural methods (psychophysics) but also occasionally conduct neuropsychological studies. Examining the visuomotor behaviour of patients who suffer from specific perceptual and spatial impairments (such as hemianopia, visual neglect, or visual form agnosia), provides another interesting approach to investigate how perceptual deficits are related to inaccurate visuomotor behaviour.
