What is the difference between a fixed ratio schedule and a variable ratio schedule?
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).
What is the difference between a fixed interval schedule and a variable interval schedule?
Variable ratio schedules maintain high and steady rates of the desired behavior, and the behavior is very resistant to extinction. Interval schedules involve reinforcing a behavior after an interval of time has passed. In a fixed interval schedule, the interval of time is always the same.
What is variable ratio schedule?
In operant conditioning, a variable-ratio schedule is a schedule of reinforcement where a response is reinforced after an unpredictable number of responses. 1 This schedule creates a steady, high rate of responding. Gambling and lottery games are good examples of a reward based on a variable ratio schedule.
When would you use a fixed ratio schedule?
An example of a fixed-ratio schedule would be delivering a food pellet to a rat after it presses a bar five times. Variable-ratio schedules occur when a response is reinforced after an unpredictable number of responses. This schedule creates a high steady rate of responding.
Why might a researcher use a variable ratio of reinforcement rather than a fixed ratio?
Variable ratio schedules of reinforcement are more resistant to extinction than fixed schedules.
What is an example of a fixed ratio schedule?
Ratio refers to the number of responses that are required in order to receive reinforcement. For example, a fixed-ratio schedule might be delivery a reward for every fifth response. After the subject responds to the stimulus five times, a reward is delivered.
What does fixed ratio mean?
The term fixed-ratio schedule of reinforcement refers to a schedule of reinforcement that relies on the principles of operant conditioning. You probably remember that in psychology, operant conditioning is a type of associative learning in which a person’s behavior changes according to that behavior’s consequences.
What is an example of fixed ratio schedule?
What is the main weakness of a fixed ratio schedule?
A disadvantage of fixed interval schedules is that the behavior is likely to become extinguished quickly if reinforcement stops.
Why is variable ratio the best?
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.
Why do ratio schedules support higher rates of responding than interval schedules?
The higher response rates observed on ratio than on matched interval reward schedules has been attributed to the differential reinforcement of longer inter-response times (IRTs) on the interval contingency.
What is an example of a variable interval schedule?
Your Employer Checking Your Work: Does your boss drop by your office a few times throughout the day to check your progress? This is an example of a variable-interval schedule. These check-ins occur at unpredictable times, so you never know when they might happen.
What is the variable ratio schedule in statistics?
The variable-ratio schedule was composed of an arithmetic sequence of 11 ratios that averaged 50; the mixed-ratio schedule consisted of equiprobable ratios of 1 and 99. Fixed-ratio values, varied over experimental conditions, included 25, 35, 50, 60, and 99.
What is the difference between fixed ratio and variable ratio reinforcement schedules?
Fixed ratios are better suited to optimize the quantity of output, whereas a fixed interval, in which the reward is not quantity based, can lead to a higher quality of output. In a variable ratio reinforcement schedule, the number of responses needed for a reward varies. This is the most powerful partial reinforcement schedule.
What is the difference between fixed and variable schedules?
These schedules are described as either fixed or variable, and as either interval or ratio. Fixed refers to the number of responses between reinforcements, or the amount of time between reinforcements, which is set and unchanging. Variable refers to the number of responses or amount of time between reinforcements, which varies or changes.
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).
