Final answer:
Discrepancy reduction aligns with approach-based motivation while discrepancy creation is in line with avoidance-based motivation. Approach motivation seeks to move closer to a goal, and avoidance motivation seeks to distance from an undesired outcome. Intrinsic and extrinsic motivations are internal and external driving forces, respectively, which can interact in complex ways.
Step-by-step explanation:
Discrepancy reduction corresponds to approach-based motivation; discrepancy creation corresponds to avoidance-based motivation. Approach motivation involves moving towards a desired goal, outcome, or reward, which leads to the reduction of discrepancy between one's current state and their desired state. Conversely, avoidance motivation entails moving away from an undesired outcome or potential threat, thereby creating a discrepancy between one's current state and a less desirable state.
In terms of intrinsic and extrinsic motivation, these concepts are essential in understanding how different types of reinforcement can impact a person. While intrinsic motivation is derived from internal factors such as personal satisfaction and enjoyment, extrinsic motivation relies on external factors like rewards and punishments. Under certain circumstances, the promise of an extrinsic reward can decrease intrinsic motivation, a phenomenon known as the overjustification effect.
