Broken heart
For most bereaved individuals, the journey through grief will ultimately culminate in an acceptable level of adjustment to a life without their loved one. The Kübler-Ross model postulates that there are five stages of grief after the loss of a loved-one: denial, anger, bargaining, depression and acceptance. And while it is recognized that mourners go through initial period of numbness leading to depression and finally to reorganization and recovery, most modern grief specialists recognize the variations and fluidity of grief experiences differ considerably in intensity and length among cultural groups, individually from person to person as well as depending on the amount of investment put into the relationship.
Grief
Other researchers such as Randolph Nesse have proposed that grief is a kind of psychological pain that orients the sufferer to a new existence without the deceased and creates a painful but instructive memory. If, for example, leaving an offspring alone at a watering hole led to the offspring’s death, grief creates an intensively painful memory of the event, dissuading a parent from ever again leaving an offspring alone at a watering hole. More recently, Winegard, Reynolds, Winegard, Baumeister, and Maner argued that grief might be a socially selected signal of an individual’s propensity for forming strong, committed relationships. From this social signaling perspective, grief targets old and new social partners, informing them that the griever is capable of forming strong social commitments. That is, because grief signals a person's capacity to form strong and faithful social bonds, those who displayed prolonged grief responses were preferentially chosen by alliance partners. The authors argue that throughout human evolution, grief was therefore shaped and elaborated by the social decisions of selective alliance partners.
