Our new paper in Communications Psychology just dropped! We found that stimulating smiling muscles boosts happiness perception in ambiguous faces—and eases visual processing. ⚡🧠😊nature.com/articles/s44271-0…

Looking ‘under the hood’, this increased likelihood was predicted by the brain’s visual response (N170). When smiling muscles were stimulated, the N170 was reduced. The larger the reduction, the higher the chance of seeing happiness

We show that recognising emotional facial expressions isn’t just a job for our visual system. It’s an embodied process. When we ‘tune in’ to our own face, it can help reduce the visual effort needed to decode ambiguous expressions

New paper just got accepted in Emotion🤓. It's called "Increasing perceived happiness in neutral faces by posing a smile: an EEG frequency-tagging study". Many thanks to my collaborators @sebkorb @svddonck @BartBoets. preprint: doi.org/10.31234/osf.io/8vy9…

In sequences containing happy oddballs, derived power at 1.2 Hz and harmonics (representing neural sensitivity to the oddball stimuli) was significantly reduced when participants were smiling themselves. This was not the case for angry oddballs.

We propose that smiling creates a facial feedback context that colours neutral faces to be somewhat happier, making them less distinguishable from actual happy faces. Cool no!?

Some of our work has been mentioned in an article in Scientific American! We show that electrical stimulation of specific facial muscles can induce positive and negative mood changes. @sebkorb @ThemisEfth

Had the most amazing time at the Redefining Emotional Expressions workshop in Erice with @sebkorb et. al. A few days of neuroscience in a medieval village atop a Sicilian mountain that overlooks vineyards and the pastel blues of the Mediterranean 🫠.

See github.com/ThemisEfth/fNMES-… for a detailed guide (including a video) on how to use a GUI developed by @ThemisEfth to control the module.

We hope that this paper and the provided materials will encourage scientists to use fNMES in their own studies! Thank you to everybody involved.

Starting to get some slides together for a conference, used AI image gen with the prompt "EEG face oscillation muscle emotion perception feedback". It delivered this monstrosity.
