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 is an example of a discriminative stimulus?
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 stimulus discrimination in operant conditioning?
Discrimination is a term used in both classical and operant conditioning. 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.
What does discriminative stimulus mean?
Discriminative Stimulus (and Generalization) 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.
Does operant conditioning have stimulus?
Classical conditioning involves associating an involuntary response and a stimulus, while operant conditioning is about associating a voluntary behavior and a consequence . ...
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.
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 the difference between stimulus generalization and discrimination?
In stimulus generalization, an organism responds to new stimuli that are similar to the original conditioned stimulus. ... On the other hand, stimulus discrimination occurs when an organism learns a response to a specific stimulus , but does not respond the same way to new stimuli that are similar.
What was Little Albert conditioned to be afraid of?
The Little Albert Experiment demonstrated that classical conditioning—the association of a particular stimulus or behavior with an unrelated stimulus or behavior—works in human beings. In this experiment, a previously unafraid baby was conditioned to become afraid of a rat .
What best defines a discriminative stimulus?
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. Past reinforcement of the resulting behavior helps the discriminative stimulus elicit the associated reaction.
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 are some examples of a stimulus?
- You are hungry so you eat some food.
- A rabbit gets scared so it runs away.
- You are cold so you put on a jacket.
- A dog is hot so lies in the shade.
- It starts raining so you take out an umbrella.
What are the 3 principles of operant conditioning?
- Reinforcement (Central Concept ): A phenomenon in which a stimulus increases the chance of repetition of previous behavior is called reinforcement. ...
- Punishment: ...
- Shaping:
What are the 4 types of operant conditioning?
This type of learning creates an association between a behavior and consequence for that behavior. The four types of operant conditioning are positive reinforcement, positive punishment, negative reinforcement, and negative punishment.
Does stimulus control appear in classical conditioning?
The stimulus controlling the operant response is called a discriminative stimulus. It can be associated directly with the response, or the reinforcer (see below). However, it usually does not elicit the response the way a classical CS does .
