👉 In developmental psychology, a developmentalist is someone who studies the development of individuals over time. They are interested in how different factors, such as genetics, environment, and social influences, influence an individual's behavior and personality traits throughout their life. Developmentalists often study children, adolescents, and adults to understand how these stages of development differ from one another and how they can be influenced by various factors. This research helps them develop theories about the different stages of development and how they relate to mental health
