What is the definition of fixed ratio?
Definition. 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.
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 psychology quizlet?
fixed-ratio schedule. In operant conditioning, a schedule of reinforcement that reinforces a response only after a specified number of responses.
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 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 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 an example of fixed ratio?
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 a variable ratio?
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 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 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.
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 an example of variable ratio in psychology?
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 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.
