1.4. A discriminative stimulus is the antecedent stimulus that has stimulus control over behavior because the behavior was reliably reinforced in the presence of that stimulus in the past. Discriminative stimuli set the occasion for behaviors that have been reinforced in their presence in the past.

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 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.

What is an example of discriminative stimuli?

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.

How does a discriminative stimulus work?

The discriminative stimulus describes something that is the trigger for a specific behavior. The discriminative stimulus comes first; then, the behavior follows as a direct result of this stimulus. The conditioned stimulus produces the response, while the discriminative stimulus signals the opportunity to respond.

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 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 discriminative stimulus quizlet?

discriminative stimulus (SD) a stimulus in the presence of which a particular response will be reinforced or punished.

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 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 ...

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.

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.

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.

What is discriminative operant and when does it happen?

The discriminated operant is an operant response that is under the stimulus control of a discriminative stimulus. Such control is established by reinforcing the response in the presence of that discriminative stimulus. For example, after appropriate training, your dog will lift his paw to the verbal command "shake."

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.

What the learner does after receiving a discriminative stimulus is called a?

What the learner does after receiving a discriminative stimulus is called a: Response or behavior. Errorless learning typically uses: Most to least prompt sequences.

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 an SD in behavior modification?

The cue, referred to as a discriminative stimulus (Sd), is a specific environmental event or condition in response to which a child is expected to exhibit a particular behavior.

Which of the below is an accurate definition for stimulus equivalence?

stimulus equivalence. describes the emergence of accurate responding to untrained and nonreinforced stimulus-stimulus relations following the reinforcement of responses to some stimulus-stimulus relations; testing must be done for reflexivity, symmetry and transitivity among stimulus-stimulus relations.

Which of the following is a stimulus that in the presence of which a response will not be reinforced?

A specific set of conditions that evokes a particular response. – The stimulus delta is defined as 'a stimulus in the presence of which a particular response will not be reinforced' (Malott, 2007, p. 202).

When a stimulus change immediately follows a response and increases the future frequency of that type of behavior in similar conditions?

For example, Cooper, Heron, and Heward (2007) define it thus: “Reinforcement. Occurs when a stimulus change immediately follows a response and increases the future frequency of that type of behavior in similar conditions” (p. 702).

When would you use discrimination training?

Everyday people frequently use discrimination training. Behavior analysts often use it to help people. It involves reinforcing a behavior in the presence of one stimulus and extinguishing it in the presence of other stimuli.

What is discrimination in psychology example?

Psychology's definition of discrimination is when the same organism responds differently to different stimuli. For example, let's say you were bitten by a dog when you were a young child. As a result, you tense up and feel nervous every time you see a dog. The dog is a stimulus which triggers a specific reaction.

What is EO in psychology?

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). An example of an EO is skipping lunch and having an empty stomach.
