Final answer:
Variable Ratio and Fixed Interval reinforcement schedules can be determined using slope to measure response rates.
Step-by-step explanation:
The schedules of reinforcement for which we can use slope to determine frequency of response rates are Variable Ratio and Fixed Interval.The Variable Ratio schedule is characterized by a varying number of responses needed for a reward. This schedule produces high and steady response rates, with little if any pause after reinforcement. An example is a gambler playing a slot machine.The Fixed Interval schedule is characterized by a set amount of time between reinforcements. This schedule yields a scallop-shaped response pattern, reflecting a significant pause after reinforcement. An example is a surgery patient receiving pain medication every four hours.
