John Bowlby argued attachment is an innate, evolutionary bond that aids survival, with a critical period in the early years. He proposed monotropy (a primary attachment figure) and an internal working model that shapes later relationships.

Lawrence Kohlberg studied moral reasoning using dilemmas such as the Heinz dilemma. He proposed three levels:

No single theory captures development. Piaget mapped how thinking changes but underestimated children and downplayed culture; Vygotsky corrected this by stressing social learning. Bowlby's attachment theory is supported by Ainsworth and Harlow but the idea of a fixed critical period is now softened to a more flexible sensitive period. Erikson extended development across the whole lifespan, which fits modern views, though his stages are hard to test precisely.
