When a response is reinforced in the presence of one stimulus and not in the presence of another, the stimulus during which reinforcement occurs is called a discriminative stimulus or SD (pronounced S-Dee) . Those conditions in which the response is not reinforced are called S-Delta.
When a behavior is reinforced in the presence of a specific stimulus but not in its absence it is known as training?
Discrimination training involves reinforcing a behavior (e.g., pecking) in the presence of one stimulus but not others.
Is the stimulus that is present when a behavior is reinforced?
10 Discriminative Stimulus . 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.
When a behavior is more likely to occur when a specific antecedent stimulus is presented we say the behavior is under?
What is stimulus control ? When a behavior is more likely to occur when a specific antecedent stimulus is present. Provide an example of stimulus control.
When a behavior only occurs in the presence of a particular discriminative stimulus what behavior is said to be under?
A conditional discrimination occurs when behavior comes under the operant control of one stimulus when it is in the presence or context of another stimulus (Catania, 1998). This arrangement is distinguished from a simple discrimination in which only one stimulus condition exerts control over a response.
How do you explain a stimulus control?
“Stimulus control is a term used to describe situations in which a behavior is triggered by the presence or absence of some stimulus . For example, if you always eat when you watch TV, your eating behavior is controlled by the stimulus of watching TV.
What is a stimulus in behavior?
Stimuli are events in the environment that influence behavior . A single stimulus can serve many different functions. Listed below are several functions that a stimulus can serve. ... An observing response is sometimes necessary for presentation of the discriminative stimulus/stimuli.
What are examples of discriminative stimulus?
- When a child asks for a candy, she always gets one during grandma’s visit, but not in her absence. ...
- When the traffic light turns green, drivers keep their car going forward, but not when the light turns red. ...
- When a manager is present, the employees work faster than when she’s not present.
What is an example of stimulus control transfer?
Transfer of stimulus control occurs when behavior initially evoked (controlled) by one S D comes under the control of a different S D . For instance, suppose that a child says cup in the presence of the echoic prompt, “Say ‘cup. ... Once a child has developed these initial skills, labeling or tact training can begin.
What is stimulus discrimination in ABA?
Stimulus Discrimination occurs when a stimuli evoke a different response . For example, not all snakes are poisonous. My husband knows how to tell the difference between poisonous snakes and non – he has discriminated these stimulus and will catch a non-poisonous snake but avoid a poisonous one.
What is an example of an antecedent stimulus?
What is the role of the teacher by the chalkboard? Even though there is a S > R connection between the teacher standing by the chalkboard and students becoming quiet and attentive, this stimulus is an antecedent (or discriminative) stimulus (not a CS). This is an example of stimulus control in operant conditioning .
What best defines a discriminative stimulus?
Discriminative stimulus serves as a trigger for specific behavior . Therefore, the discriminative stimulus occurs first and the behavioral response occurs in response to the stimulus. The stimulus is discriminative because it triggers a specific response.
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.
How do you develop a stimulus control?
Reinforcement and extinction of behaviors are the fundamentals in creating stimulus control. When the stimulus is present, the desired behavior is reinforced. When the stimulus is absent, the behavior is ignored or put on extinction.
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.
How do we know when stimulus control takes place?
A behavior is said to be under stimulus control when there is an increased probability that the behavior will occur in the presence of a specific antecedent stimulus or a stimulus for of a specific stimulus class .
