Final answer:
The discovery stage in Layton's model of forgiveness involves intense introspection and a reevaluation of beliefs. Kübler-Ross's model outlines the grief process as denial, anger, bargaining, depression, acceptance. Erikson identified integrity versus despair as the challenge for older adults in their development.
Step-by-step explanation:
Layton's three-stage model of forgiveness describes the discovery stage as where everything we believe about life is being called into question. This stage can be challenging as it requires deep introspection and the possible overhaul of long-held beliefs and values. This process of questioning can be unsettling but is critical for intellectual and personal growth.
The order of stages in Kübler-Ross's five-stage model of grief is denial, anger, bargaining, depression, acceptance, which supports individuals in their journey of processing loss. Meanwhile, in Erik Erikson's developmental stages of life, older people struggle with overcoming despair to achieve integrity, reflecting a period of life where reflection on past experiences is crucial to developing a sense of fulfillment.
