Eye Movements and Expressive Faces

In our daily life, we are exposed to various stimuli. For example, when we walk to a town, we see lots of things: colorful clothes, shop windows, and expressive faces. As we get bombarded by the different information that we receive, we can only process so much. Thus, we filter this information into what we consider as relevant, which will then be reacted upon. Of all this information, our attention inevitably shifts from one thing to another.

“This shift in attention is often accompanied by a movement of the eyes,” says Kulke, a researcher in the Department of Affective Neuroscience and Psychophysiology at the University of Göttingen. In the current study, she combined two methods to investigate what happens in the brain during this attention shift: eye-tracking and EEG. With the Eye-Tracker, research volunteers sat in front of a device that records eye movements. Kulke then showed them standardised faces with different emotional expressions. At the same time, EEG measured brain waves via electrodes placed on their head.

What did she find out in this study, and what questions can be asked based on these findings? The answer is at Neuroscience News.
