Psychology dating young adulthood
According to Freud (1949), a human being's first encounter with intimate behavior is with his or her mother during the act of breast-feeding.
This new way of transitioning into adulthood is different enough from generations past that it is considered a new developmental phase - Emerging Adulthood.
The development of a unique interpersonal style is a function of temperament (Mc Adams, 1989).
Emerging adulthood has been proposed as a new life stage between adolescence and young adulthood, lasting roughly from ages 18 to 25.
The median marriage age for men was around 22, and married couples usually had their first child about one year after their wedding day.
All told, for most young people half a century ago, their teenage adolescence led quickly and directly to stable adult roles in love and work by their late teens or early twenties.
