Positive means the addition of a stimulus, like getting dessert after you finish your veggies, and negative means the removal of a stimulus, like getting a night of no homework because you did well on an exam.
Pozitivno znači da zadaju podražaj, poput deserta nakon pojedene porcije povrća, a negativno da uklanjaju podražaj, poput oslobađanja od zadaće jer ste dobro riješili ispit.
