However, mastery of a stage is not required to advance to the next stage. Erikson's stage theory characterizes an individual advancing through the eight life stages as a function of negotiating his or her biological forces and sociocultural forces. Each stage is characterized by a psychosocial crisis of these two conflicting forces (as shown in the table below). If an individual does indeed successfully reconcile these forces (favoring the first mentioned attribute in the crisis), he or she emerges from the stage with the corresponding virtue. For example, if an infant enters into the toddler stage (autonomy vs. shame & doubt) with more trust than mistrust, he or she carries the virtue of hope into the remaining life stages.[1]
