A growing social psychological literature reveals that brief interventions can benefit disadvantaged students. We tested a key component of the theoretical assumption that interventions exert long-term effects because they initiate recursive processes. Focusing on how interventions alter students’ responses to specific situations over time, we conducted a follow-up lab study with students who participated in a difference-education intervention two years earlier. In the intervention, students learned how their social-class backgrounds matter in college (Stephens, Hamedani, & Destin, 2014). The follow-up study assessed participants’ behavioral and hormonal responses to stressful college situations. We found that all difference-education versus control participants more frequently discussed their backgrounds in a speech, indicating they retained the understanding of how their backgrounds matter. Moreover, first-generation participants (i.e., whose parents do not have four-year degrees) in the difference-education versus control condition showed greater physiological thriving (i.e., anabolic balance), suggesting they experienced their working-class backgrounds as a strength.
An intervention designed to reduce the gap between first- and continuing-generation college students used senior students' real-life stories to illustrate how students' diverse backgrounds can shape what they experience in college. The intervention eliminated the social-class achievement gap by increasing first generation students' tendency to seek out college resources, improving their GPAs.
