Which of the following is true of a variable ratio schedule and operant conditioning?
Which of the following is true of a variable-interval schedule in operant conditioning? It reinforces a behavior after an inconsistent and unpredictable amount of time has elapsed.
What is variable ratio in operant conditioning?
In operant conditioning, a variable-ratio schedule is a partial schedule of reinforcement in which a response is reinforced after an unpredictable number of responses. 1 This schedule creates a steady, high rate of response. Gambling and lottery games are good examples of a reward based on a variable-ratio schedule.
What is variable interval schedule in operant conditioning?
In operant conditioning, a variable interval schedule is when the reinforcement is provided after a random (unpredictable) amount of time has passes and following a specific behavior being performed.
What is a variable interval ratio schedule?
Variable Interval Schedule. Interval schedules involve reinforcing a behavior after an variable interval of time has passed. In a variable interval schedule, the interval of time is not always the same but centers around some average length of time.
What is the difference between fixed ratio and variable ratio?
The variable ratio schedule is unpredictable and yields high and steady response rates, with little if any pause after reinforcement (e.g., gambler). A fixed ratio schedule is predictable and produces a high response rate, with a short pause after reinforcement (e.g., eyeglass saleswoman).
Why do variable ratio schedules produce steady rates of responding?
Variable ratio schedules produce steady rates of responding because it's impossible to determine which response will result in a reinforcer.
What is a variable schedule?
In operant conditioning, a variable-interval schedule is a schedule of reinforcement where a response is rewarded after an unpredictable amount of time has passed, which is the opposite of a fixed-interval schedule. This schedule produces a slow, steady rate of response. 1
Why is variable ratio the most effective?
Variable ratios In variable ratio schedules, the individual does not know how many responses he needs to engage in before receiving reinforcement; therefore, he will continue to engage in the target behavior, which creates highly stable rates and makes the behavior highly resistant to extinction.
What’s a variable schedule?
In operant conditioning, a variable-interval schedule is a schedule of reinforcement where a response is rewarded after an unpredictable amount of time has passed, which is the opposite of a fixed-interval schedule.
What do fixed variable-interval and ratio mean in the context of operant conditioning?
Variable-ratio schedule of reinforcement (VR): Reinforcement after an unpredictable number of responses. Fixed-interval schedule of reinforcement (FI): Reinforcement after a specified amount of time. Variable-interval schedule of reinforcement (VI): Reinforcement after an unpredictable amount of time.
Why do variable ratio schedules produce steady rates of responding quizlet?
Variable ratio schedules produce high and steady rates of response with little or no post reinforcement pauses. Variable ratio schedules help account for the persistence some people display in regards to certain maladaptive behaviors. The unpredictable nature of these activities results in a very high rate of behavior.
Is variable ratio the best?
Among the reinforcement schedules, variable ratio is the most productive and the most resistant to extinction. Fixed interval is the least productive and the easiest to extinguish (Figure 1).
Which schedule of reinforcement requires the completion of a variable number of responses to produce a reinforcer?
A ratio schedule requires that a completion of a number of responses occur before reinforcement is received, where as an interval schedule requires the occurrence of at least one correct response after a set period of time before reinforcement is received.
Which schedule of reinforcement requires the completion of a variable number of responses to produce a reinforcer quizlet?
fixed ratio schedules often produce high rates of response. the size of the ratio can influence the rate of response. schedule of reinforcement requires the completition of a variable number of responses to produce a reinforcer.
What is required for a ratio schedule to produce reinforcement?
Ratio schedule require a certain number of operant responses (e.g., 10 responses) to produce the next reinforcer. The required number of responses may be fixed from one reinforcer to the next (Fixed Ratio schedule) or it may vary from one reinforcer to the next (Variable Ratio schedule).
Which schedule of reinforcement requires completion of a variable number of responses to produce a reinforcer?
A ratio schedule requires that a completion of a number of responses occur before reinforcement is received, where as an interval schedule requires the occurrence of at least one correct response after a set period of time before reinforcement is received.
Which schedule of reinforcement requires the completion of a specified unvarying number of responses to produce a reinforce?
fixed ratio schedules often produce high rates of response. the size of the ratio can influence the rate of response. schedule of reinforcement requires the completition of a variable number of responses to produce a reinforcer.
Why do variable ratio reinforcement schedules produce such high rates of responding?
Variable-ratio schedules occur when a response is reinforced after an unpredictable number of responses. This schedule creates a high steady rate of responding. Gambling and lottery games are good examples of a reward based on a variable ratio schedule.
What is the difference between variable ratio and variable interval schedules of reinforcement?
Variable refers to the number of responses or amount of time between reinforcements, which varies or changes. Interval means the schedule is based on the time between reinforcements, and ratio means the schedule is based on the number of responses between reinforcements.
Which schedule of reinforcement is a ratio schedule stating a ratio of responses to reinforcements?
Variable Ratio Schedule (VR) Variable ratio schedules deliver reinforcement after a variable number of responses are made. This schedule produces high and steady response rates.
What is the difference between variable interval and variable ratio?
Variable Intervals The difference between variable ratio and the variable interval schedule is that the rates of behaviors are low because it is based on the passage of a specific time period, and not the number of responses.
What is a ratio schedule of reinforcement?
In operant conditioning, a fixed-ratio schedule is a schedule of reinforcement where a response is reinforced only after a specified number of responses. Essentially, the subject provides a set number of responses, then the trainer offers a reward.
