An Introduction to Reward and Addiction
0 Views •
2023
Consequences play a major role in controlling our behavior. If the consequence is a reward, then it encourages the associated behavior. Rewards can come in many forms such as a pleasant feeling, money, or food. However, sometimes an individual engages in compulsive behavior despite of negative consequences, and this state is known as addiction. Administration of addictive substances is neurochemically rewarding, which ultimately causes a loss of control in limiting the intake. Scientists aim...

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...

This manuscript describes a protocol to examine the olfactory system of rodents. The olfactory habituation/dishabituation test will allow investigators to determine whether a mouse habituates to a repeatedly presented odor and whether the mouse demonstrates dishabituation when presented a novel odor.

FAQs
A cue gains behavioral significance when it repeatedly precedes a particular consequence. Responses become stronger toward cues associated with favorable outcomes, while responses decline when cues predict less reward or no reward. This relationship allows investigators to examine how learning links environmental information with action selection, rather than treating behavior as independent of surrounding conditions.
Changes in reinforcement schedules or reward value can shift which responses organisms favor. A response linked to a more valuable outcome may receive stronger preference, whereas altered reinforcement can weaken an established response or increase selection of another option. Comparing behavior under these conditions helps reveal how motivation and learning contribute to discrimination performance.
Reward discrimination provides a way to study cognitive flexibility because behavior may need to adjust when previously favorable options become less rewarding or unrewarded. Researchers can examine whether organisms continue responding to an old cue or shift toward a better alternative. These changes help distinguish persistent learned preferences from adaptive decision-making under changing conditions.
A study typically presents organisms with cues, actions, or choices linked to different outcomes, then records responses across repeated experiences. Investigators compare selection or responding for more rewarding, less rewarding, and unrewarded alternatives. These observations provide behavioral measures of learning, decision-making, motivation, and adjustment to differing reinforcement conditions.
Researchers use this approach when they need to examine how organisms learn outcome differences and use that information to guide behavior. It can support studies of motivation, decision-making, cognitive flexibility, development, and addiction. The method is also relevant when researchers investigate behavioral patterns associated with impaired decision-making.
Because the process can be examined through observable choices and responses, investigators can study it across species while varying reward value, reinforcement schedules, or environmental conditions. Cross-species comparisons can clarify broad behavioral principles of learning and motivation. Findings may also provide context for developmental research and disorders involving altered decision-making.
