Which of Piaget's stages lasts from birth to about 2 years of age?

A. identity moratorium: Moratorium describes individuals in active crisis/exploration but without a firm commitment; therefore it does not match “commitment but no crisis.”
B. identity foreclosure: Foreclosure describes making a commitment without having undergone a crisis or exploration (often adopting others’ expectations); this matches “made a commitment but not experienced a crisis.”
C. identity achievement: Achievement is the status after undergoing a crisis/exploration and then making a commitment, so it requires a prior crisis.
D. identity diffusion: Diffusion describes lack of both exploration (crisis) and commitment, the opposite of the status described.

A. authoritarian: Authoritarian parents impose many rules and expect obedience with little warmth or encouragement of independence; this does not match “placing limits but encouraging independence.”
B. indulgent: Indulgent (permissive) parents are high in warmth/involvement but place few limits or demands, so they do not fit the description of setting limits.
C. neglectful: Neglectful (uninvolved) parents provide few demands and low involvement; they do not actively encourage the child’s independence.
D. authoritative: Authoritative parents combine clear, reasonable limits with warmth and encouragement of autonomy and independence; this matches the description.
