Künstliche Intelligenzflecken verborgene Anzeichen von Depressionen in (japanischen) Mandesausdrücken der Studenten

>The results revealed a consistent pattern. Students who reported subthreshold depressive symptoms were rated by their peers as less friendly, expressive, and likable. Interestingly, they were not judged as more stiff, fake, or nervous. This suggests that StD does not make people appear overtly negative but rather tones down their positive expressivity.

>Artificial intelligence analysis revealed specific patterns of eye and mouth movements, such as the inner brow raiser, upper lid raiser, lip stretcher, and mouth-opening actions that were more frequent in participants with StD. These subtle muscle movements were strongly linked to depression scores, even though they were too fine for untrained observers to pick up on.

>The researchers note that their study was conducted with Japanese students, an important consideration given that cultural norms influence how people express emotions.

OK, we don’t really have a good and definitive idea of what depression is, what exactly causes it and definitely not how to treat it. Could we just get a handle on that before we do this?
