Jean Berko

Jean Berko is a psychologist known for her research on how children learn language. She conducted the famous "Wug Test," which demonstrated that children can understand and apply grammatical rules they've never been explicitly taught. For example, when shown a made-up creature called a "wug," children can correctly pluralize it as "wugs," showing they grasp how to apply language patterns. Her work helped scientists understand the cognitive processes behind language development and how children internalize grammar rules naturally.
