Definitions:

Fixed-Interval Reinforcement

A schedule of reinforcement where a response is rewarded only after a specified time has elapsed, leading to a pattern of responses following the passage of each interval.

Variable-Interval Reinforcement

A reinforcement schedule in which a response is rewarded after an unpredictable amount of time has passed.

Continuous Reinforcement

A learning schedule in which every correct response is followed by a reward, thus reinforcing the behavior consistently.

Partial Reinforcement

A conditioning schedule where only some responses are reinforced, leading to greater resistance to extinction.
