Scenario 2  In the bustling city of Oakwood, a psychology lab has launched a new initiative to study the effects of social media on mood disorders in urban adolescents. The research team, led by Dr. Demir, includes psychologists, graduate students, and volunteers. Together, the team conducts regular surveys, interviews, and observational studies to answer their questions. The research center also engages the local community by offering workshops for parents and educators on promoting healthy social media habits. The project aims to deepen the understanding of social media’s impact on mental health and provide practical recommendations for fostering positive online experiences.   In one focus group meeting, a diverse group of adolescents including Khari, Mateo, & Sophia discuss their own social media habits and the pressures they feel to present a perfect image online. Following the focus group with the adolescents, the researchers interviewed the parents to discuss both social media use and emotional outcomes from social media. After the interviews, the parents were provided with psychological treatment resources for adolescents, including referrals to a local mental health clinic.  Dr. Demir’s graduate student, Blair, is particularly interested in understanding the relationship between social media use and developmental variables. Blair’s eagerness to make discoveries sometimes leads to impatience with Dr. Demir’s meticulous research methods. Blair sometimes wants to rush to conclusions, while Dr. Demir routinely insists on thorough analysis.
