Recognising a face

How do we recognise a face?

Research degree student, Daniel Feuerriegel is at the Face Categorisation Laboratory at the Université Catholique de Louvain in Belgium investigating how the brain does just this.

Daniel is learning about the newly developed fast periodic visual stimulation technique.

“When you present an image, let’s say at 5 times per second, you get rhythmic brain activity at the frequency at which you are presenting that image,” Daniel says.

“Their [Face Categorisation Lab] fast periodic visual stimulation technique records the brain activity with an electroencephalogram (pictured below).

“I’m using image repetition and rhythmic entrainment of brain activity to investigate how repetition of different information in a face, for example gender, age and emotion, will give us different signals in the brain.”

Daniel is spending six months with the Head of the Face Categorisation Lab, Professor Bruno Rossion, conducting experiments to understand the factors contributing to effects observed using this technique.

The knowledge and experience gained in Belgium will assist Daniel in his own research investigating the relationship between repetition effects and predictive coding.
