In behavioral psychology, reinforcement is a strengthening of a specific behavior due to its association with a stimulus. Reinforcement is an important part of operant or instrumental conditioning. A reinforcer is the stimulus that strengthens the behavior, in contrast to punishment that weakens the behavior. The effect of reinforcement may be measured as an increase in the frequency of its expression, duration, magnitude, or decrease in latency. Although in many cases a reinforcing stimulus is a rewarding stimulus which is "valued" or "liked" by the individual, this is not a requirement. Indeed, reinforcement does not even require an individual to consciously perceive an effect elicited by the stimulus. Furthermore, stimuli that are "rewarding" or "liked" are not always reinforcing: if an individual eats at McDonald's and likes the taste of the food, but believes it is bad for their health, they may not eat it again and thus it was not reinforcing in that condition. Thus, reinforcement can only be assumed if there is a causal link between the stimulus and the enhancement of behavior.
