Developmental research is a field of study focused on understanding how individuals grow, change, and develop over time. This includes examining biological, psychological, and social factors that influence development from infancy through old age. Researchers in this area may study various aspects of human development, such as cognitive, emotional, social, and behavioral changes that occur at different stages of life. Developmental research aims to identify patterns and processes of growth and development, as well as factors that may hinder or facilitate healthy development. This field helps to inform interventions and programs aimed at promoting positive development and well-being across the lifespan.
