A discriminative stimulus (Sd or S^D) is created when the response is reinforced in its presence, but not when it is absent^​1​. For example, a child requests to watch TV and historically, he is granted more screen time when his Mom has to get on a conference call for work, but never when she doesn't have to take a call.

What is a discriminative stimulus?

The discriminative stimulus is the cue (stimulus) that is present when the behavior is reinforced. The animal learns to exhibit the behavior in the presence of the discriminative stimulus.

Which is the best example of stimulus discrimination?

An instance of stimulus discrimination is if a child swears on the playground. The other children would be reinforcing which makes them an SD. If the child says the same thing in front of grandma and grandpa, no reinforcement will occur, making them the SΔ.

What is a discriminative stimulus give an example quizlet?

An event or stimulus that precedes an operant and sets the occasion for an increase in operant behavior. ... Examples of a discriminative stimulus: Green Light, Open Sign, etc. • A stimulus that sets the occasion for a decrease in operant responses.

What is an example of an SD?

This is a stimulus that has a history of signaling the availability of reinforcement. For example, a Starbucks Coffee sign signals the availability of coffee. If you are tired, seeing a Starbucks sign signals the availability of reinforcement (coffee).

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.

What is an EO in ABA?

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). ... By being hungry it increases the value of food and increases the behaviors that gain access to food.

What is the role of discriminative stimuli in operant conditioning?

(symbol: S^D) 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 stimulus Delta?

A stimulus in the environment that signals the non-availability of reinforcement. For example, if you need to go to the bathroom and there is an Out of Order” sign on the door. This signals the non-availability of relieving (negative reinforcement) yourself in that bathroom.

What is a stimulus give two examples that are not from the text?

What is a stimulus? Give two examples that are not from the text. A stimulus is any physical event or object in the environment that can be detected by one's sense receptors and can affect behavior. For example, the sound and sight of an airplane passing overhead are stimuli.

Does the presence of a discriminative stimulus cause a behavior to occur?

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 less likely to occur in the presence of the S-Delta.

When a discriminative stimulus influences a Behaviour that Behaviour?

A discriminative stimulus influences the occurrence of an operant response because of the contingencies of schedules of reinforcement or paradigms of reinforcement/punishment that are or have been associated with that response.

When a discriminative stimulus influences a Behaviour that Behaviour quizlet?

When a discriminative stimulus influences a behaviour, that behaviour: is said to be under stimulus control.

Why is it called discriminative stimulus?

The discriminative stimulus sets up the occasion for a specific behavior to occur because the resulting behavior has been reinforced in the past. The stimuli are discriminatory because they are specific and elicit a specific response.

What is a discriminating stimulus MCAT?

discriminating stimulus: stimulus presented before a reinforcer/punishment, to signal availability and increase probability of responding.

What is a negative discriminative stimulus?

A negative discriminative stimulus, or “ess delta” is one in the presence of which the response is not reinforced. Because the reinforcer always occurs after a response, the reinforcer can come to serve as a stimulus. As a stimulus, it can signal whether the next response is likely to be reinforced or not.

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.

What is the overall intent for delivering a discriminative stimulus?

What is the overall intent for delivering a discriminative stimulus? To get an individual to engage in particular behavior.

What stimulus parameters determine whether a stimulus will acquire discriminative control?

The two stimulus parameters that determine whether a stimulus will acquire discriminative control are stimulus disparity (the magnitude between the positive and the negative stimulus/ physical difference) and stimulus salience (the magnitude of the difference between the discriminative stimuli and the background ...

What is a discriminative response?

The discriminative-response process involves control of responding by antecedent stimuli. ... When tone and light were then presented together for the first time in a stimulus-compounding test, response rates were determined by the discriminative-response process.

What is the difference between EO and Mo?

The term MO is an umbrella term for EO (establishing operations) and AO (abolishing operations); where EO increases the consequence's effect (or need for) and AO decreases the consequence's effect (i.e., reduces need for).

What is the difference between EO and AO?

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 term did Keller and Schoenfeld introduce?

Keller and Schoenfeld (1950) adopted the term establishing operation to describe the effect of antecedent manipulations, such as food deprivation, on the strength of a response.

What is an example of discrimination learning?

Examples of discrimination learning in everyday life can include grocery shopping, determining how to decipher between the types of bread or fruit, being able to tell similar stimuli apart, differentiating between different parts while listening to music, or perhaps deciphering the different notes and chords being ...

What is the function of a discriminative stimulus quizlet?

Discriminative stimulus (SD) - a controlling stimulus that sets the occasion for reinforcement of an operant.
