Steinberg defines love in terms of intimacy, passion, and commitment, which he claims exist in varying levels in different romantic relationships.
Early adolescent relationships are characterized by companionship, reciprocity, and sexual experiences.
Interpersonal relationships are formed in the context of social, cultural and other influences.
The context can vary from family or kinship relations, friendship, marriage, relations with associates, work, clubs, neighborhoods, and places of worship.
Securely attached infants miss the parent, greet them happily upon return, and show normal exploration and lack of fear when the parent is present.
Insecure avoidant infants show little distress upon separation and ignore the caregiver when they return; they explore little when the parent is present.
As emerging adults mature, they begin to develop attachment and caring qualities in their relationships, including love, bonding, security, and support for partners.
