The concept of “tasks” comes from developmental psychology and was originally defined by Robert Havinghurst at the University of Chicago. Developmental tasks are important in child development as the child is required to accomplish various emotional, social, physical, and mental tasks as he or she adapts to the challenges of life. If these tasks are not mastered at lower levels of development, they can influence the mastery of similar tasks at a higher level. It is important to note that the tasks of mourning are influenced by the various mediators of mourning, including who died, the nature of the attachment, the type of death, the way the loss impacts the person’s sense of self, previous experiences with loss, how well these losses were handled, levels of social support, and secondary losses caused by the death, to name but a few.
