Answer:
Fixed ratio
Explanation:
The Fixed ratio schedule is used in ope-rant conditioning. Ope-rant conditioning is work on the relationship of response and stimulus due to that the behavior of a subject has been changed.
As the name indicated the reinforcement is being given after a fixed ratio for example after every ten times the reinforcement is provided to the rat in the box. So the rat can learn the behavior.
In this type of reinforcement, the schedule will remain constant. If the reinforcement is not provided after a fifth, tenth or any fixed number then it won't be a fixed ratio.
Black and white cultures developed separately from each other, the separation created a stigma for either race toward the other, as a subject of the taboo. There was a constant tension, a relationship that bred whites to feel superior and blacks to feel inferior. It also heavily affected literature, music, and art for both races - leading to "White Man's Burden", "Uncle Tom's Cabin", as well as the explosion of new styles of music coming from the black newly freedmen/women of the south. It was a terrible and but extremely influential and creative period for black culture.
