discriminative stimulus การใช้

• The antecedent stimulus is called a discriminative stimulus ( S D ).
• Note that a motivating operation differs from a discriminative stimulus ( Sd ).
• This is the opposite of a discriminative stimulus which is a signal that reinforcement will occur.
• When using time delay procedures, a prompt is initially given immediately after the desired discriminative stimulus.
• The goal of response prompting is to transfer stimulus control from the prompt to the desired discriminative stimulus.
• A discriminative stimulus signals the availability of reinforcement, while a motivating operation changes the effectiveness of a reinforcer.
• The fact that the discriminated operant occurs only in the presence of the discriminative stimulus is an illustration of stimulus control.
• When the extinction of a response has occurred, the discriminative stimulus is then known as an extinction stimulus ( S? or " S-delta " ).
• The discriminated operant, also known as the three-term contingency, has three components : an antecedent discriminative stimulus, a response, and a reinforcing or punishing consequence.
• In addition to its SSRI properties, alaproclate has been found to act as a non-competitive NMDA receptor antagonist, but does not have discriminative stimulus properties similar to phencyclidine.
• For instance, in an operant chamber, if food pellets are only delivered when a response is emitted in the presence of a green light, the green light is a discriminative stimulus.
• In a public display situation, the audience's attention is focused on the animal, rather than the trainer; therefore the discriminative stimulus is generally gestural ( a hand sign ) and sparse in nature.
• Ro64-6198 was able to be recognised as a discriminative stimulus by rats distinct from other opioid receptor ligands, but was not able to produce the conditioned place preference thought to be indicative of addictive potential.
• He found that responses decreased over time at a slower rate when a discriminative stimulus was present, even without reinforcement, and concluded that discriminative stimuli act as a filter, or a kind of secondary reinforcement.
• Specifically, operant conditioning refers to the three-term contingency that uses stimulus control, in particular an antecedent contingency called the discriminative stimulus ( SD ) that influences the strengthening or weakening of behavior through such consequences as reinforcement or punishment.
• Furthermore, ( + )-CPCA dose dependently antagonizes cocaine-induced locomotion and potentiates the discriminative stimulus effects of a low dose of cocaine . ( + )-CPCA, unlike cocaine, does not enhance cocaine-induced convulsions.
• The dinner bell is the reinforcing stimulus ( the children will come inside of the house again when they want food ), and the dinner bell is the discriminative stimulus ( the children know food is available when the dinner bell rings ) ( see Stimulus Control ).
• In James Dinsmoor s first work, he compared the rate at which behavior ( bar-pressing for food among rats ) decreased over time in the presence of a discriminative stimulus without reinforcement, a reinforcing stimulus without the discriminative stimulus, and in the presence of no stimulus.
• In James Dinsmoor s first work, he compared the rate at which behavior ( bar-pressing for food among rats ) decreased over time in the presence of a discriminative stimulus without reinforcement, a reinforcing stimulus without the discriminative stimulus, and in the presence of no stimulus.
• As small chains become mastered, i . e . are performed consistently following the initial discriminative stimulus prompt, they may be used as links in larger chains . ( Ex . teach hand washing, tooth brushing, and showering until mastered and then teach morning hygiene routine which includes the mastered skills ).
