A teacher implements a reward system so that students will pay more attention in class. This describes which of the main goals of psychology?
Improving learning
Improving brain development
Changing behavior
Explaining behavior

The implementation of a reward system aligns with the goal of changing behavior, as it seeks to modify students’ attention patterns through positive reinforcement. By rewarding attentive behavior, the teacher is essentially guiding students towards a desired behavioral outcome, demonstrating the practical application of behavioral psychology in classroom settings.

Moreover, this approach can lead to improved academic performance and engagement in learning. When students associate positive experiences with focused attention, it fosters a more conducive learning environment. Ultimately, rewarding positive behaviors not only enhances individual student performance but also benefits the classroom dynamic as a whole.
