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.
14.
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.

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 ).
