What is an example of stimulus discrimination training?

For example, if a child responds “4” in the presence of the question “What is 2 + 2,” the behavior of saying “4” will be reinforced, but saying “4” will not be reinforced in the presence of the question “What is 2 + 5?” Accordingly, the child is trained to discriminate between those stimuli that do and do not signal …

What is stimulus discrimination?

It involves the ability to distinguish between one stimulus and similar stimuli. In both cases, it means responding only to certain stimuli, and not responding to those that are similar.

Why does post reinforcement pause occur?

While both fixed ratio and fixed interval show a post-reinforcement pause, the fixed ratio has a high steady rate. This is due to the fact that immediately after the reinforcement is delivered there is a decrease in responding, and before the next scheduled opportunity there is an increase in responding behavior.

What happens when a discriminative stimulus is present?

The presence of a discriminative stimulus causes a behavior to occur. Stimulus discrimination training may also occur with punishment. A behavior is less likely to occur in the presence of the SD. A behavior is more likely to occur in the presence of the S-Delta.

Why is continuous reinforcement least resistant to extinction?

In continuous schedules, reinforcement is provided every single time after the desired behavior. Due to the behavior reinforced every time, the association is easy to make and learning occurs quickly. However, this also means that extinction occurs quickly after reinforcement is no longer provided.

Which of the following is an example of stimulus fading?

Taking a line drawing of a bed and slowly changing it into the letters b-e-d to help a child learn to read the word bed. All of these are examples of stimulus fading. Printing a child’s name on a piece of paper and having him trace his name.

What are the most effective schedules of reinforcement?

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).

What is the difference between a stimulus and a discriminative stimulus?

What is the difference between a stimulus and a discriminative stimulus? A stimulus is a person, place or thing in someone’s sense receptors while a discriminative stimulus is a stimulus in the presence of which a response will be reinforced. A stimulus does not necessary mean a response will be reinforced.

What is a disadvantage of continuous reinforcement?

The advantage to continuous reinforcement. is that the desired behavior is typically learned quickly. The disadvantage to continuous reinforcement. is difficult to maintain over a long period of time due to the effort of having to reinforce a behavior each time it is performed.

Why is variable interval most resistant to extinction?

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.

Which reinforcement schedule is least resistant to extinction?

Extinction of a reinforced behavior occurs at some point after reinforcement stops, and the speed at which this happens depends on the reinforcement schedule. Among the reinforcement schedules, variable-ratio is the most resistant to extinction, while fixed-interval is the easiest to extinguish.

What is good stimulus control?

Good stimulus control refers to a strong correlation between the occurrence of a particular stimulus and the occurrence of a particular response. For example, good stimulus control would be displayed if a driver consistently stops the car at red traffic lights.

What makes reinforcement more effective?

We must remember 4 different variables that effect reinforcer effectiveness. They are: deprivation/satiation, immediacy, size, and contingency. 1) Deprivation/Satiation: Often referred to as not enough or too much of a good thing! Deprivation: Not having access to something that is highly desirable.

Is partial or continuous reinforcement seen as stronger?

Partial reinforcement, unlike continuous reinforcement, is only reinforced at certain intervals or ratio of time, instead of reinforcing the behavior every single time. This type of reinforcement is regarded more powerful in maintaining or shaping behavior.

What is fading in autism?

Fading, an applied behavior analysis strategy (ABA), is most often paired with prompts, another ABA strategy. Fading refers to decreasing the level of assistance needed to complete a task or activity. When teaching a skill, the overall goal is for the student to eventually engage in the skill independently.

What is prompting and fading in disability?

Prompting and Fading. Definition: Prompts are used to increase the likelihood that a child will provide a desired response. Fading is gradually reducing the prompt.
