Background: Substance use disorders (SUD) can be considered disorders in the way people process incentives, learn, and make decisions. To understand why some people develop SUD, researchers need to develop reliable tests that show how people think and learn. This natural history study seeks to develop a set of tasks that could then be used to test how people learn and make decisions. Objective: To develop and validate behavioral tasks that could be used in future studies. Eligibility: Healthy people aged 18-45 years from the Baltimore area. They must also be enrolled in the NIDA screening protocol. Design: Participants will perform different tasks. Most tasks require 1-4 study visits; some may require up to 12. Visits are 1-14 days apart. All visits will last about 1-7 hours. Participants will perform tasks on a computer. As they work they may be given different stimuli: Smells. Participants will sniff odors through a plastic tube or mask on their nose. Flavors. Participants will wear a mouthpiece and small amounts of different flavored liquids will be placed in their mouth. Pictures. Participants will look at different images. Sounds. Participants will wear headphones and various sounds will be played for them. Food. Participants may be asked to eat a meal before, during, or after a task. The researchers will provide the meal. During each task, participants will wear sensors to monitor their heart rate, blood pressure, breathing, and other physical changes in t…
