What is an example of a discriminative stimulus?
Teaching a child to request a snack: The discriminative stimulus might be the presence of the snack in the room. When the snack is present, the child is more likely to ask for it. If the snack is not present, the child is less likely to ask for it.
What is an example of a motivating operation?
For example, if a child is hungry (a motivating operation), food becomes highly reinforcing. In this case, food can serve as a powerful reinforcer to increase the likelihood of the child engaging in behaviors that lead to obtaining food, such as requesting or following instructions.
What is the difference between SD and motivating operation?
Note that a motivating operation differs from a discriminative stimulus (Sd). A discriminative stimulus signals the availability of reinforcement, while a motivating operation changes the effectiveness of a reinforcer. Nine main unconditioned (i.e. not learned) motivating operations, have been identified in humans.
What is the difference between MOS and SDs?
SDs signal that reinforcement is available, but the MO is what actually impacts us to engage in the behavior, to access that reinforcer. For example, a pen is an SD that signals ink to put something on paper, given the behavior of writing.
What is a real life example of motivating operations and discriminative stimuli?
Simply: motivating operations make you want or not want something, discriminative stimuli lets you know it’s available. You are driving down the road and Jimmy Buffet’s “Margaritaville” comes on the radio. Suddenly, you are craving a margarita. The song was the MO increasing the value of a margarita.
Which is the best example of stimulus discrimination?
Only ordering a dish at one restaurant because you know that other restaurants don’t offer that same menu item is an example of stimulus discrimination. Your cat being able to tell the difference between hearing you open a bag of chips and you opening a bag of cat treats is another example.
What is the difference between MO and EO?
MO’s are environmental factors that impact how effective a reinforcer is. MO’s can either be Establishing Operations (EO’s) or Abolishing Operations (AO’s). An EO is an MO that increases how reinforcing something is, and an AO is an MO that decreases how reinforcing something is.
What is the difference between stimulus control and motivating operations?
Definition: The distinction between a motivating operation (MO) and stimulus control is that an MO alters the effectiveness of a reinforcer while stimulus control alters the behavior itself in some way (frequency, magnitude, etc.) (Cooper, Heron, and Heward, 2020).
What is an example of an SD in ABA?
Consider the following examples: Traffic Light: A green light serves as an SD for drivers to proceed through an intersection. Ringing Phone: The sound of a ringing phone is an SD for answering the call. Doorbell: Hearing the doorbell ring signals that someone is at the door and should be greeted.
What is the difference between stimulus control and discriminative stimulus?
In behavioral psychology, stimulus control is a phenomenon in operant conditioning that occurs when an organism behaves in one way in the presence of a given stimulus and another way in its absence. A stimulus that modifies behavior in this manner is either a discriminative stimulus or stimulus delta.
What is the MO and SD behavior?
The MO is a state of deprivation, the need. It’s this state that impacts behavior and the value of something as a reinforcer. The SD signals the availability of those reinforcers. At this moment, I’m not deprived of thirst, something being cut, so it’s not reinforcing.
What is the difference between MOs and SDS quizlet?
What is the useful contrast between SDs and MOs? Sds are related to the differential availability of a currently effective form of reinforcement for a particular type of behavior. MOs are related to the differential reinforcing effectiveness of a particular type of environmental event.
What do MOs and SDS have in common?
A:Motivating operations (MOs) and SDs are both antecedent variables that alter the current frequency of some behavior. They are both operant variables.
What are examples of discriminative stimulus?
An example of a discriminative stimulus is when a child engages in the target behavior of cleaning their room when a parent is present, but not engaging in the behavior when the parent is not present. The parent is the discriminative stimulus they influences the target behavior of cleaning the room.
What are the 4 effects of motivating operations?
A motivating operation has two independent effects: Value-Altering Effect. A change in the effectiveness of a stimulus to function as a reinforcer (increase or decrease). Behavior-Altering Effect.
What is an example of a discriminative stimulus dog?
Discriminative stimuli are signals such as words, hand or body signals, people, locations, etc. So, for a quick example, the word “Sit” is a signal that tells the dog that if it puts its butt down it will be rewarded.
What is an example of stimulus response in real life?
Salivating in response to the smell of food is a good example of a naturally occurring stimulus. During this phase of the process, the unconditioned stimulus (UCS) results in an unconditioned response (UCR). 4 Presenting food (the UCS) naturally and automatically triggers a salivation response (the UCR).
What is the difference between stimulus and motivation?
Motivation and stimulation differ in their nature – stimulation is always extrinsic incentive for labour and motivation is the attitude of the worker himself to the labour. They are certainly interrelated – the higher material stimuli are, the more efficient the employee works.
Does a discriminative stimulus cause a behavior?
Each discriminative stimulus signals the opportunity to earn reinforcement for one particular behavior or suite of behaviors. This positively trained discriminative stimulus always ‘opens the door’ to positive reinforcement. If the behavior does not occur, the only result is that no reinforcement occurs.
What is eo and ao in aba?
Establishing Operation (EO) – increases the current effectiveness of some stimulus, object, or event as reinforcement. Abolishing Operation (AO) – decrease the current effectiveness of some stimulus, object, or event as reinforcement.
What is EO in functional analysis?
An establishing operation (EO) is a motivating operation that increases the value of a reinforcer and increase the frequency in behavior that provides access to the reinforcer (Cooper, Heron & Heward, 207, p. 695).
What is an example of a discriminative stimulus quizlet?
Discriminative stimulus is a stimulus in the presence of which a response will be reinforced; it is a cue that a particular response will pay off. A stimulus that I would like to establish as an SD for a friend, is a no smoking sign in the house. I would like my friend to quit smoking while in my house.
What is an example of an SD?
Consider the following examples: Traffic Light: A green light serves as an SD for drivers to proceed through an intersection. Ringing Phone: The sound of a ringing phone is an SD for answering the call. Doorbell: Hearing the doorbell ring signals that someone is at the door and should be greeted.
What is a discriminative stimulus AP Psychology?
(symbol: SD) in operant conditioning, a stimulus that increases the probability of a response because of a previous history of differential reinforcement in the presence of that stimulus.
What is an example of discriminative stimulus in dogs?
Discriminative stimuli are signals such as words, hand or body signals, people, locations, etc. So, for a quick example, the word “Sit” is a signal that tells the dog that if it puts its butt down it will be rewarded.
What is the difference between motivating operations and discriminative stimuli?
What are discriminative stimuli?
How can motivating operations be manipulated?
How do motivating operations affect behavior?
Hey there, behavior analysts! Today we’re diving into the fascinating world of motivating operations and discriminative stimuli. These two concepts are crucial for understanding how behavior works, and they’re often confused. So, let’s get this straight.
What’s a Motivating Operation (MO)?
Think of a motivating operation as something that changes the value of a reinforcer and influences the likelihood of a specific behavior. It’s like setting the stage for behavior.
For example, imagine you’re super thirsty after a long run. That thirst is a motivating operation that makes water highly reinforcing. You’re going to be much more likely to search for water and drink it. It’s an establishing operation (EO) because it makes the water more valuable and likely to occur.
But what about when you’re full after a huge meal? You probably won’t be as motivated to eat another plate of cookies. That’s a abolishing operation (AO) because it decreases the value of the cookies as a reinforcer and makes you less likely to eat them.
The Discriminative Stimulus (SD)
Now, let’s talk about discriminative stimuli or SDs. These are cues or signals that tell us when a particular behavior is likely to be reinforced.
Think of a traffic light. When the light turns green, you know you can drive and will be reinforced by getting to your destination.
But when the light is red, you know driving will result in a punishment, such as a ticket. The red light is a discriminative stimulus that tells you not to drive.
How They Work Together
Here’s the cool part – motivating operations and discriminative stimuli often work together to influence behavior.
Let’s go back to our thirsty runner. They might see a water fountain (the SD) and know that drinking from it will satisfy their thirst (the reinforcer). That’s because their thirst (the EO) has made the water fountain a more valuable SD.
But if they’re not thirsty (AO), the water fountain won’t be as appealing, even though it’s still an SD.
Examples of Motivating Operations and Discriminative Stimuli
Let’s dive into some real-life examples to solidify these concepts:
1. Food Deprivation and a Snack Machine
Motivating Operation: Food deprivation (EO) – The individual is hungry, increasing the value of food as a reinforcer.
Discriminative Stimulus: A snack machine (SD) – The individual sees the snack machine and knows it dispenses food, which is now a highly reinforcing outcome.
2. Feeling Cold and a Blanket
Motivating Operation: Feeling cold (EO) – Makes warmth highly reinforcing.
Discriminative Stimulus: Seeing a blanket (SD) – Knowing the blanket provides warmth, the individual is more likely to use it.
3. Studying for a Test and Getting a Good Grade
Motivating Operation: The desire to get a good grade (EO) – Makes good grades a valuable reinforcer.
Discriminative Stimulus: The presence of a test (SD) – Indicates that studying will be reinforced with a good grade.
Key Differences
Here’s a quick breakdown of the key differences between motivating operations and discriminative stimuli:
| Feature | Motivating Operation | Discriminative Stimulus |
|———————|————————————————-|—————————————–|
| Focus | Value of reinforcer and likelihood of behavior | Reinforcement for behavior |
| Effect | Changes the value of the reinforcer | Signals the availability of reinforcement |
| Example | Hunger makes food more reinforcing | A traffic light signals when you can drive|
Understanding the Difference is Key
Recognizing the differences between motivating operations and discriminative stimuli is important for developing effective interventions in behavior analysis.
For example, if you want to increase a child’s willingness to complete homework, you need to consider both motivating operations and discriminative stimuli:
Motivating Operation: Make homework more reinforcing by offering a reward, like a favorite toy.
Discriminative Stimulus: Use a visual timer or a specific phrase to signal when it’s time to do homework.
FAQs
Let’s address some common questions about motivating operations and discriminative stimuli:
1. Can a single stimulus be both an MO and an SD?
Yes, definitely! Take a hungry person seeing a cookie. The cookie is an SD because it signals that eating it will be reinforced. But it’s also an EO because the person’s hunger makes the cookie more valuable as a reinforcer.
2. What are some other examples of motivating operations?
Here are a few more examples of motivating operations:
Deprivation: A lack of food, water, sleep, or social interaction.
Satiation: Feeling full or having too much of something.
Aversive stimulation: Unpleasant situations or experiences that increase the value of escaping or avoiding them.
3. How are these concepts used in therapy?
Motivating operations and discriminative stimuli are fundamental in behavior analysis. We use them to understand behavior and develop interventions to change it. For example, in therapy for individuals with autism, we might identify motivating operations that make certain activities more reinforcing and use discriminative stimuli to help the individual learn and perform those activities.
4. What are the limitations of these concepts?
Motivating operations and discriminative stimuli are useful tools, but they are not perfect. There are factors that can influence behavior that these concepts don’t fully capture, such as the individual’s history of reinforcement and their cognitive abilities.
5. What are some resources to learn more?
You can find lots of information about motivating operations and discriminative stimuli in textbooks and online resources. Check out the works of influential behavior analysts like Cooper, Heron, and Heward, and look for articles on the Association for Behavior Analysis International (ABAI) website.
Conclusion
Motivating operations and discriminative stimuli are vital concepts for understanding how behavior works. When you understand these concepts, you’re on your way to better understanding behavior, designing effective interventions, and making a real difference in the lives of others.
