providing the response occurs within a set period at the end of the interval.
Produces similar results to fixed ratio schedules
- A high steady rate until reinforced
- A post-reinforcement pause
- Strain with large increases in the interval
- Moderate RTE
Examples in natural environments
- Baking a cake. The time required to bake a cake is usually fixed, but if
you wait too long beyond that time, the cake will burn. There is only a limited
window beyond the time required in which to take out the cake.
- Waiting for a bus. Buses are supposed to arrive at stops at fixed intervals,
and the passenger will miss the bus if they are not there at the time the
Examples in video games
- Waiting for a monster to re-spawn on a crowded server. If monsters re-spawn
at regular intervals the player must wait for a fixed period of time to kill
the monster. However, if they are not there at the time the monster re-spawns,
the monster is likely to be killed by another player.
- Obtaining objects, treasures, or power-ups that only appear for a limited
