as 是副词, 意思是"跟...一样地,同样地", 修饰sharply, 与sharply一起作状语修饰动词understand.

When it isn't, we're not able to understand other people's feelings as sharply.
相当于:
When empathy isn't reinforced after the eatliest period of childhood, we're not able to understand other people's feelings as sharply as the people whose empathy was reinforced after their eatliest period of childhood.
意思是"当同情心没有被及时强化时, 我们理解他人的情感时就不如那些同情心得到了及时强化的人来得敏感".
