Merced Experimental Social and Health (MESH) Psychology LaboratoryWe aim to understand health decision making and behavior through a social psychological lens. Most of our work occurs at the intersection of health decision making and behavior (e.g., screening, sunscreen use) and the self (e.g., self-perception), and typically focuses on understanding how people prepare for and respond to bad news. |
Principal Investigator: Jennifer L. Howell, PhD
Her research focuses on the intersection of social psychology and health. She is particularly interested in how processes surrounding the self (e.g., defensiveness, social comparison) influence health decision-making and behavior. More about Dr. Howell and her vita are available here. |

Graduate Students
I am NOT currently accepting graduate students (to begin in the 2020-2021 or the 2021-2022 school years).
Details for those wishing to start Fall 2022: Applicants interested in joining the lab should submit their materials to the UCM graduate program http://graduatedivision.ucmerced.edu/prospective-students/how-apply.
Visit: http://psychology.ucmerced.edu/graduate-program for more information on applying.
I encourage interested applicants to email me (howell@ucmerced.edu) with questions.
Undergraduate Students
I recruit new students to work in my lab each semester. Research assistants are responsible for running participants in studies, helping with the development of study materials, piloting study materials, and entering and proofing data. As students advance, there can also be opportunities for lab management positions and individual or small-group research.
Undergraduates interested in working in my lab should send me (howell@ucmerced.edu) and Angela Johnson (ajohnson98@ucmerced.edu) an email with their application form (link below) attached. The earlier the better!
I have four criteria in selecting undergraduate research assistants:
1. I require a two-semester commitment (Fall and Spring, or Spring and Fall; We may want volunteers over the summer, but it does not count toward the two semester commitment).2. Must be outgoing and extraverted.
3. Must be willing to work in the lab up to 8 hours per week (actual hours will vary throughout the semester) and attend a 1-hour weekly lab meeting (The lab meeting is at 10am on Fridays).
4. Must have completed introductory psychology with a B or better
Please note that we make decisions at the end of each semester for the next semester. So, if you apply early in the semester, it may be a little while before we make our decisions. To check on the status of your application, you can email Angela Johnson (ajohnson98@ucmerced.edu)
