The ease with which we identify other people's emotions based on their facial expressions can depend on the person we're looking at. For example, people are less accurate at reading facial expressions of emotions in members of other ethnic, cultural and regional groups. Pum Kommattam investigates misinterpretation of facial expressions in such intergroup contexts. He wants to find out whether people also show biases in perceived intensity of emotions in ethnic ingroup and outgroup members. He also looks at misinterpretation of emotions that communicate opposing social intentions.
