(2). Toddlerhood(2–4 years): this stage of psychosocial development is known as the Autonomy vs. Shame/Doubt stage.
(3). Early childhood(5–8 years): this stage of psychosocial development is known as the Initiative vs. Guilt stage.
(4). Middle Childhood(9–12 years): this stage of psychosocial development is known as the Industry vs. Inferiority stage.
(5). Adolescence(13–19 years) : this stage of psychosocial development is known as the Identity vs. Role Confusion stage.
(6). Early adulthood(20–39 years) : this stage of psychosocial development is known as the Intimacy vs. Isolation stage.
(7). Middle Adulthood(40–59 years): this stage of psychosocial development is known as the Generativity vs. Stagnation stage.
(8). Late Adulthood(60 and above): this stage of psychosocial development is known as the Ego Integrity vs. Despair stage.
