Explanation:

Freud proposed a psychosexual development theory consisting of sequential stages (oral, anal, phallic, latency, genital), which are a series of steps. Aristotle focused on teleology, Locke on empiricism ("blank slate"), and Terman on intelligence testing—none centered on developmental steps as Freud did.
