Answer:
fixed interval; fixed ratio
Step-by-step explanation:
Fixed-interval schedule is a reinforcement schedule where the initial response is only rewarded after a defined period of time has elapsed.
This schedule leads to high amounts of response close to the end of the period but reacts far slower instantly after the reinforcer has been delivered.
Acme Chemical plant employees receive a weekly paycheck. Every Fridays the employee receives reinforcement, which can lead in a greater response rate as payday approaches.
A fixed-ratio schedule, however, is a reinforcement schedule where reaction is only strengthened after a specified number of responses. A fixed-ratio schedule, for instance, could be a reward for every fifth answer.
A reward is given after the subject answers the stimulus five times. They office employees are getting paid for every fifth sale they make.
