Yes, the longer you boil the hops, the more bitter the beer becomes, and vice versa. And to an extent, a middle ground will offer both.
The closer to flameout you add the hops, the less bitterness you get and the more aroma.
Hops have acids and oils. The boil time determines the bitterness, however, as you boil, the oils that give the hop aroma, breakdown and are basically evaporated.
Hence why the longer the boil, the more bitter/less aroma you get, and vice versa. You can play around with the times to suit if you like it more or less bitter/aromatic. Aroma will also contribute to a hop "taste/flavor," since our sense of smell is linked pretty closely to taste.
If your looking for more flavor, do a 1oz addition at around 15-20 min. If you like that fresh hop "bite" (think Sierra Nevada Torpedo if you've had it), do it even later (say 5min)
