The purpose of this research is to understand how the emotions of people with different
mental health concerns (e.g., people with schizophrenia, people with major depressive
disorder) differ from individuals without mental health concerns. A large body of literature
suggests that people with mental illnesses have emotional abnormalities compared to healthy
individuals, but a number of these abnormalities are not well understood. For example, often
people with schizophrenia report on questionnaires that they experience fewer pleasant
emotions when talking with other people, but some evidence suggests these individuals report
a similar amount of pleasant emotion when they are actually engaged in a pleasant activity.
Thus, it is unclear the extent to which reports of emotional abnormalities extend to a more
real-world setting. In the tasks in the current proposal, participants will engage in a
series of tasks designed to assess their emotional functioning. These tasks involve viewing
emotional stimuli on the computer, engaging in social interactions, and consuming small
amounts of food. In all tasks, participants will make ratings of their experiences of
pleasure (and displeasure). We will then compare the experiences of patient groups to those
of healthy individuals to test how emotional ratings might differ across these tasks.
