An individual is playing a video game where 'rare items' drop from defeated enemies on average once every 100 defeats. The player defeats enemies as quickly as possible and continues playing for hours even when no items drop. This behavior is most consistent with:

  1. Negative reinforcement, as the player is trying to remove the enemies.
  2. A Fixed-Interval schedule producing a scallop pattern in gameplay.
  3. A Fixed-Ratio schedule with a post-reinforcement pause after each item drop.
  4. A Variable-Ratio schedule producing a high response rate and high resistance to extinction.
