Reward Prediction
The brain works ahead of experience.
Evidence: established. We label every concept honestly, and say so when it's a teaching model. How we rate evidence.
Shrink Definition
Reward prediction refers to the brain's estimate of how rewarding a future experience is likely to be. Rather than simply responding after rewards occur, the brain continuously predicts future rewards based on previous learning. Those predictions influence attention, motivation, planning, and behavior long before rewards actually arrive.
Plain language
Much of motivation comes from expecting a reward, not receiving it.
Shrink Insight
Expectation often drives behavior more powerfully than reality.
Why it matters
Reward prediction helps explain: anticipation excitement procrastination gambling investing addiction habit formation motivation Expectations shape decisions every day. Sometimes accurately. Sometimes not.
Common misunderstanding
Reward prediction isn't optimism. It's an unconscious computational process continuously updated through learning.
Medical boundary
This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
Evidence summary
Reward prediction forms one of the central ideas within computational neuroscience and reinforcement learning. Decades of research support its role in adaptive decision making.
