Developmental Psychology

Groups the studies whose central finding concerns how thought, behavior or social bonds change across the life span, especially in infancy and childhood. Belongs here: Ainsworth's Strange Situation, Harlow's Rhesus Monkey Experiments, Piaget's Conservation Experiments, the Sally-Anne Test, the Stanford Marshmallow Experiment, the Still Face Experiment and the Visual Cliff Experiment. A study of an adult social process, even one that also appears in children, is filed under social psychology unless development itself is the study's point.
