What is a fixed ratio?
Fixed ratio is a schedule of reinforcement. In this schedule, reinforcement is delivered after the completion of a number of responses. The required number of responses remains constant. The schedule is denoted as FR-#, with the number specifying the number of responses that must be produced to attain reinforcement.
What is fixed interval ratio in psychology?
In operant conditioning, a fixed-interval schedule is a schedule of reinforcement where the first response is rewarded only after a specified amount of time has elapsed.
What is fixed ratio and fixed interval?
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.
What is an example of a fixed ratio schedule of reinforcement?
This schedule produces a high, steady rate of responding with only a brief pause after the delivery of the reinforcer. An example of a fixed-ratio schedule would be delivering a food pellet to a rat after it presses a bar five times.
What is a variable ratio in psychology?
What Is a Variable-Ratio Schedule? The American Psychological Association defines a variable-ratio schedule as "a type of intermittent reinforcement in which a response is reinforced after a variable number of responses."2. Schedules of reinforcement play a central role in the operant conditioning process.
What is an example of variable ratio?
In a lab, psychologists would study variable ratio reinforcement with animals. They might train an animal to press a button a few times in order to receive a treat. The “few times” would vary every time the treat was given to the animal.
What is an example of a fixed interval schedule?
A fixed interval is a set amount of time between occurrences of something like a reward, result, or review. Some examples of a fixed interval schedule are a monthly review at work, a teacher giving a reward for good behavior each class, and a weekly paycheck.
What is variable interval in psychology?
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.
Which is the best example of 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.
What is the difference between fixed and variable schedules?
A fixed ratio schedule is predictable and produces a high response rate, with a short pause after reinforcement (e.g., eyeglass saleswoman). The variable interval schedule is unpredictable and produces a moderate, steady response rate (e.g., restaurant manager).
What is fixed ratio schedule?
Fixed Ratio Schedule. Ratio schedules involve reinforcement after a certain number of responses have been emitted. The fixed ratio schedule involves using a constant number of responses. For example, if the rabbit is reinforced every time it pulls the lever exactly five times, it would be reinforced on an FR 5 schedule …
What is an example of a fixed ratio?
"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 an example of fixed interval in psychology?
A fixed interval is a set amount of time between occurrences of something like a reward, result, or review. Some examples of a fixed interval schedule are a monthly review at work, a teacher giving a reward for good behavior each class, and a weekly paycheck.
What is an example of variable ratio in psychology?
Learning Objectives
| Reinforcement Schedule | Description | Example |
|---|---|---|
| Variable ratio | Reinforcement is delivered after an unpredictable number of responses (e.g., after 1, 4, 5, and 9 responses). | Gambling |
What is fixed 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.
