Disenfranchised grief
There are many models for dealing with grief. The Kubler-Ross model describes grieving in five steps or stages: denial, anger, bargaining, depression, and acceptance (Kubler-Ross, 1969). In other words, in order to begin grieving one must first endorse the loss, and then express emotion. The griever must then accept the loss and adjust to the change the death or loss caused in his or her life (Cordaro, 2012). Over the years, however, how grief is conceptualised has moved away from predictable stages that lead to 'recovery' or 'closure', towards an understanding of grief that addresses the complexity and diversity of the grieving experience (Australian Psychological Society, 2016). Models such as Worden's tasks of grief (2008) and the Dual-Process model (Stroebe and Schutt,1999) offer frameworks for dealing with grief in a way that enhances the self awareness of the grieving person (Australian Psychological Society, 2016).
Grief
When a baby chimpanzee or gorilla dies, the mother will carry the body around for several days before it may finally be able to move on without it; this behavior has been observed in other primates, as well. Jane Goodall has described chimpanzees as exhibiting mournful behavior toward the loss of a group member with silence and by showing more attention to it. And they will often continue grooming it and stay close to the carcass until the group must move on without it. Another notable example is Koko, a gorilla that uses sign language, who expressed sadness and even described sadness about the death of her pet cat, All Ball.
