Dr. Guntuku & Personality in Images
Dr. Guntuku & Personality in Images
Dr. Sharath Chandra Guntuku works at the University of Pennsylvania's Centre for Digital Health, studying how images and text from social media can be used to explore and investigate health and personality. Although Dr. Guntuku is a computer scientist by training -- he earned his Ph.D. from the School of Computer Science and Engineering in the Nanyang Technological University, Singapore -- he works closely with a team of psychologists at the World Well Being Project and the Positive Psychology Center to research psychological phenomena in social media.
Dr. Guntuku doesn't analyze social media content by hand -- instead, he uses computer vision and natural language processing to 'view' images or 'read' text, and machine learning and statistical analyses to ask and answer questions of health and psychology. Before beginning this line of work, Dr. Guntuku studied the expression of personality traits through multimedia preferences and helped build learning frameworks for facial recognition.

Find a picture that you feel captures your personality. This can be a photo you’ve taken yourself or one you’ve found online. You don’t have to share it here, but you can if you like. Upload it to Imagga’s Auto-Tagging Demo (the program used by Dr. Guntuku in some of his research) and see how the image is tagged.
Complete the Big Five Personality Test and keep track of your scores. Note: In the linked test, you can right-click the ‘results summary’ image (pictured here) to save it to your hard drive.
Read the article (included to the right), the ‘Analysis’ section of the linked study, and the slides from a presentation about the study.

Reflection Questions
Reflection Questions
Based on the results in Dr. Guntuku’s study (such as the tag clusters and the in-text descriptions) and slideshow, as well as the results of your personality test, does your chosen image describe your personality well? If yes, what aspects of the Big Five does it accurately describe, and how so? If no, what Big Five traits does it describe, and how similar are you to this theoretical person?
The online article describes how analyzing people’s personalities can relate to persuasion techniques. Pick a topic or issue that is important to you, and think about how you would persuade someone to agree with you. How would your approach differ based on their personality -- for instance, would you use the same arguments for someone who was high in neuroticism versus someone low in neuroticism, even if they were similar in all other traits?
