Postformal thought

Developmental psychology initially focused on childhood development through Jean Piaget's four stages of human cognitive development, the last stage of which is known as the formal operational stage. Extending developmental psychology to adults, most neo-Piagetian theories of cognitive development have posited one or more stages of postformal thought. Postformal thought is also addressed by some non-Piagetian theories of developmental psychology, including Michael Commons' model of hierarchical complexity and Otto Laske's constructive developmental framework.
