What is the variable ratio?
A schedule of reinforcement in which a reinforcer is delivered after an average number of responses has occurred.
What is an example of fixed ratio in psychology?
"Ratio" refers to the number of responses that are required in order to receive reinforcement. For example, a fixed-ratio schedule might involve the delivery of a reward for every fifth response. After the subject responds to the stimulus five times, a reward is delivered.
What is variable interval psychology?
A variable interval schedule (VI) is a type of operant conditioning reinforcement schedule in which reinforcement is given to a response after specific amount of time has passed (an unpredictable amount of time), but this amount of time is on a changing/variable schedule.
How do you find the variable ratio?
To calculate the variable expense ratio, simply divide the company's total variable expenses by the company's total net sales. To express the result as a percentage, simply multiply it by 100.
What is variable ratio and variable interval?
Variable ratio schedules maintain high and steady rates of the desired behavior, and the behavior is very resistant to extinction. Fixed Interval Schedule. 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 an example of a variable interval?
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 difference between variable ratio and variable interval?
Variable ratio schedules maintain high and steady rates of the desired behavior, and the behavior is very resistant to extinction. Interval schedules involve reinforcement of a desired behavior after an interval of time has passed.
Is a pop quiz a variable ratio?
Pop quizzes work on a variable-interval schedule of reinforcement. To get good grades (reinforcement) on pop quizzes, which come at inconsistent and unknown passages of time (variable interval), you must keep up on class work and assignments (behavior).
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.
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).
Is age a ratio variable?
The short answer: Age is considered a ratio variable because it has a “true zero” value. It's possible for an individual to be zero years old (a newborn) and we can say that the difference between 0 years and 10 years is the same as the difference between 10 years and 20 years.
What is an example of variable interval?
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.
Why is variable ratio the most effective?
In the fixed-ratio schedule, resistance to extinction increases as the ratio increases. In the fixed-interval schedule, resistance to extinction increases as the interval lengthens in time. Out of the four types of partial reinforcement schedules, the variable-ratio is the schedule most resistant to extinction.
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.
What is an example of a variable-interval?
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.
Is height a ratio variable?
Variables like height, weight, enzyme activity are ratio variables. Temperature, expressed in F or C, is not a ratio variable.
Is gender an interval or ratio?
nominal For example, gender and ethnicity are always nominal level data because they cannot be ranked. However, for other variables, you can choose the level of measurement.
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).
Is IQ an interval or ratio?
interval scale An IQ (Intelligence Quotient) score from a standardized test of intelligences is a good example of an interval scale score.
Is height an interval or ratio?
Physical characteristics of persons and objects can be measured with ratio scales, and, thus, height and weight are examples of ratio measurement.
Is age a interval or ratio?
ratio variable Age is considered a ratio variable because it has a “true zero” value. It's possible for an individual to be zero years old (a newborn) and we can say that the difference between 0 years and 10 years is the same as the difference between 10 years and 20 years.
Is Gender an interval or ratio?
nominal For example, gender and ethnicity are always nominal level data because they cannot be ranked. However, for other variables, you can choose the level of measurement.
