Applied Behavior Analysis Technician (ABAT) Practice Test

In behavior analysis, what does a fixed ratio schedule reinforce?

1. The first response after a duration of time

2. A set number of responses

3. A variation of responses

4. The environment of the responses

The correct answer is: A set number of responses

A fixed ratio schedule reinforces a set number of responses. This means that a specific number of responses must be completed before a reward or reinforcement is provided. For example, if a program operates on a fixed ratio of 5, the individual must perform the desired behavior five times to receive reinforcement. This type of schedule creates a clear and predictable pattern for the individual, helping establish a relationship between their actions and the receipt of reinforcement based on their specific output. The other options represent different types of behavioral schedules or concepts that do not align with the definition of a fixed ratio schedule. Reinforcement based on the first response after a certain duration describes a fixed interval schedule. A variation of responses does not specifically relate to the fixed ratio schedule but is more characteristic of variable schedules. Lastly, focusing on the environment of the responses does not pertain to reinforcement schedules but rather to the context or conditions under which behaviors occur.
