Final answer:
Adler proposed that birth order impacts personality, with oldest children becoming overachievers, youngest children potentially being spoiled, and middle children having the opportunity to minimize negative dynamics. However, research has not conclusively confirmed Adler's theories.
Step-by-step explanation:
Adler's concept of the order of birth suggests that our position in our family's birth order impacts our personality. According to Adler, the oldest children often become overachievers due to needing to share their parents' attention, while the youngest children may be spoiled. Middle children, like Amy, have the opportunity to minimize the negative dynamics of the older and younger siblings. It's important to note that while Adler's theory is widely known, research has not definitively proven its validity.
