Ignoring

 

IÕm interested in how we actively ignore aspects of the environment. Most of the time we think about ignoring as the by-product of attention. If I attend to this webpage, then I am, by default, ignoring the rest of my computerÕs desktop. On the other hand, if I know that an annoying pop-up window will appear, IÕ ll want to ignore that even if the focus of my attention changes. Similarly, if I know my friend has not got off the train yet, I can choose to ignore all the people already at the station and wait for new arrivals. I can choose to do this, even if I am not sure what my friend will be wearing.

 

IÕve combined various methods – psychophysics, cognitive reaction time studies, fMRI and computational modeling – to unpack which parts of this active ignoring are shared with other processes (e.g. segmentation) and which are unique (e.g. suppression).

 

The ability to ignore distractions changes with age. Perhaps this makes us more aware of our surroundings or open to new experiences, but it also makes it more difficult to stay focused on one place or task. IÕm investigating the perceptual and neural effects of age on ignoring. IÕve found that some older adults are able to maintain the ability to ignore distractions but use a different set of brain regions, compared to young people, to do so.

 

Motion Processing and Driving

 

My PhD compared different models of the motion processing network and I have maintained an interest in motion processing ever since. More recently I have investigated how the neural mechanisms of motion processing are affected by distracting attention away from motion. IÕve also investigated how older adults process braking or deceleration (leading to a collaboration with the Transport Research Laboratory).

 

Distorted attention

 

The things that attract our attention change with our priorities. IÕm involved with several projects investigating the role of distorted attentional priorities. For example, do people who have to control their food intake (due to obesity or Diabetes) react differently when they look at food. In another project IÕm investigating whether manipulating clay during therapy changes how people are able to ignore distracting or emotionally difficult thoughts.
