Researchers are interested in training a mouse to navigate through an obstacle course. They begin by placing the mouse at the end of the obstacle course, and giving it a food pellet when it presses the button. The researchers then move the mouse back one obstacle, and once the mouse makes it past the obstacle, it receives another food pellet by pressing the button again. The researchers then continue to move the mouse back one obstacle each time until the mouse is able to complete the entire obstacle course. Which of the following does this scenario best exemplify?
A)
Chaining combined with positive reinforcement.
B)
Chaining combined with negative reinforcement.
C)
Shaping by successive approximation combined with negative reinforcement.
D)
Shaping by successive approximation combined with positive reinforcement.
