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).
Animal grief
There are different “categories” of emotions known as primary and secondary emotions. Bekoff explains that primary emotions are similar to reflex or something along the lines of fear or fight-or-flight response. Therefore, it is something that animals react to such as loud noises, unknown objects, or odors (Bekoff, 2000). Having primary emotions is crucial because reactions to these are important for an animal's survival. The part of the brain that is responsible for primary emotions is the limbic system (Bekoff, 2000).
