Twitter users with depression and anxiety were found to be more likely to post pictures with lower aesthetic values and less vivid colors, particularly images in grayscale, according to a new study led by researchers at Penn Medicine. Additionally, they found that users tended to suppress positive emotions rather than outwardly display more negative emotions, such as keeping a straight face instead of outright frowning, in their profile pictures. The study sought to utilize computer vision and artificial intelligence to determine what qualities of photos posted to and set as profile images on Twitter could be associated with depression and anxiety, with an eye toward using the platform as a method of screening for both. The research will be presented at the International AAAI Conference on Web and Social Media June 11-14 in Munich.
