The goal gradient effect is a psychological phenomenon in which people are more motivated to pursue a goal when it is closer, and the closer they get to the goal, the more motivated they become. The effect is named after the shape of a graph of motivation versus distance to goal, which is called a goal gradient.

This psychological effect has been found in a wide variety of situations, including studies of animals, humans, and even computer simulations. In one famous study, rats were placed in a maze with a food reward at the end. The rats were found to run faster as they got closer to the food, even when the food was not visible.

It is used to explain a wide variety of human behavior, including shopping, gambling, and even exercise. The effect has also been used to design more effective marketing campaigns and to improve customer satisfaction.
