In my research I am interested in the interaction between action and perception. The ‘actions’ I investigate are hand movements. Our hands are very important to interact with our environment: we use them all the time to manipulate objects.
The manipulation of an object starts with grasping and lifting it. This might seem easy, but if we don’t want to squeeze a fragile object such as an egg, for example, we have to scale our fingertip forces and grip to the object properties. At the same time, we receive information about these properties by getting feedback from sensors in the skin. This is very useful if we have never touched the object before as it allows us to learn how to handle it.
In one of my projects, I am investigating how the scaling of forces is related to our perception of object weight. To investigate this, I use precise force sensors to investigate how forces are planned and controlled in the lifting of objects of different weight. I also ask participants how heavy they think objects are. By comparing these measures, we have recently found that the planned forces influence how heavy an object feels (van Polanen & Davare, 2015).
In addition, I am looking at which brain areas are involved in the control of these action and perceptual systems. I use transcranial magnetic stimulation to stimulate the brain and evaluate how this affects the control of movements.
I have a background in Human Movement Sciences and in psychophysics (the study of perception). After I finished my bachelor Human Movement Sciences at VU Amsterdam in the Netherlands, I continued to master Human Movement Sciences at the same university. As part of my master, I performed a research internship in at the Manchester Metropolitan University in the United Kingdom. In this project, I studied the eye–hand coordination in pointing tasks.
After graduating, I started a PhD on haptic perception at Utrecht University and continued this position after two years at the VU Amsterdam. During these four years, I investigated the haptic saliency of object properties with haptic search tasks. If a property is salient, this means it is processed very efficiently. Therefore, it can be felt very easily and quickly. In addition, I looked at the exploration movements that are made when haptically searching for object properties.
Currently, I am working at the KU Leuven in Belgium, where I explore the relations between action and perception in grasping movements. At the Motor Control and Neuroplasticity lab, I have the opportunity to also investigate the brain areas that are important in controlling action and perception systems.
