What are the long-term differences between securely and insecurely attached infants?

1. None, because infantile amnesia means nothing from the first three years is
remembered

2. None, because psychologists do not really use the word "attachment' after infancy

3. While there are some differences through the preschool years, these disappear by the
time children are school-aged

4. Securely attached infants have healthier relationships later in life

5. Securely attached infants become dependent on their parents later in life
