A hunter sits in a blind waiting for a deer to pass by. The appearance of a deer is completely unpredictable, but on average, one passes every 4 hours.

Which schedule is this, and how does it affect the hunter's persistence compared to a hunter who knows deer pass exactly at 6 AM and 6 PM?

  1. Fixed-interval; it produces a 'scallop' where the hunter only looks at 4-hour marks.
  2. Fixed-ratio; it produces a post-reinforcement pause after a deer is spotted.
  3. Variable-interval; it produces more persistent waiting that is harder to extinguish.
  4. Variable-ratio; it produces a higher rate of checking the horizon.
