Several theoretical perspectives can be applied to the study of mother-son relationships and romantic storylines. Attachment theory, for example, suggests that the mother-son relationship is critical to a son's attachment style and his ability to form healthy relationships in adulthood (Bowlby, 1969). Social learning theory suggests that mothers play a significant role in socializing their sons, teaching them important life skills, and modeling relationships and behaviors (Eagly, 2005).
