What about theories?
Dr. Mary Piñon, Coordinator of MS Programs in Psychology with the School of Psychology at Walden University, shares her views about the importance of theory and the research connection.
Developmental psychology is scientific in nature, which means it is grounded in theory. A theory is empirically based, meaning it relies on research to support it. As more research-based evidence is generated, theories are adjusted to reflect that evidence. In developmental psychology, theories are used to explain physical, cognitive, and/or social emotional changes at different developmental periods. Theories and research go hand in hand, as research shapes theories and theories drive new research.
