a) Puberty in early adolescence, usually starting around the ages of 10 or 11, is where most children experience sexual attraction to others that affect social life both in school and out

b) Puberty accentuates gender role differences for at least some teenagers

For example:

• Some girls who excelled at math or science in elementary school may fear that these subjects would limit their attractiveness as girls
• Some boys may start playing sports to affirm their masculinity
• Some boys and girls who once worked together successfully on class projects may no longer feel comfortable doing so
