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

A. active euthanasia: Jack Kevorkian is associated with actively hastening death (providing lethal means or administering lethal injection) to end patients’ lives, which is characterized as active euthanasia/physician-assisted suicide.
B. life wills: Life wills (living wills) are advance directives stating treatment preferences; Kevorkian’s activities involved direct assistance in dying, not drafting or promoting living wills.
C. passive euthanasia: Passive euthanasia involves withholding or withdrawing life-sustaining treatment; Kevorkian’s interventions were active rather than passive.
D. advance directives: Advance directives are legal documents expressing future care wishes; they are different from the direct, active assistance in dying for which Kevorkian is known.

A. morality: This is a broad term for principles of right and wrong; it doesn’t specify Kohlberg’s level/stage about pursuing self-interest.
B. conventional morality: Conventional morality centers on social rules, conformity, and maintaining relationships or social order, not primarily on individual self-interest.
C. post conventional morality: Postconventional morality emphasizes abstract principles and social contracts/universal ethics, beyond simple self-interest.
D. pre-conventional morality: Preconventional morality (stage 2, individualism/exchange) describes behavior guided by self-interest where individuals pursue their own interests but recognize others may do the same.
