Large-Scale Online Studies of Early Motor Skill Learning

Background: Our goal is to gain insight into early human motor skill learning by carrying out online substudies using online crowd-sourcing tools. Objective: To learn more about motor behavior in a large group of people using motor tasks, and questions. Eligibility: Adults ages 18 and older based in the U.S. who speak English Design: Participants will be recruited from a crowd-sourcing website like Amazon Mechanical Turk. Participants will do online tasks. They can use their own computers anywhere with Internet access. They will not need to directly interact with researchers. Participants will be asked for general data, like their age and gender. No personally identifiable data will be collected. Participants will see a list of tasks on their computer screen. They will be able to choose tasks they wish to do. They will get a description of the experiment, how long it takes, and how much compensation they will get. Participants will complete on their screen a motor behavioral task, a cognitive task, and/or a questionnaire. For example, they may be asked to press sequences of numbers on the keyboard or move the mouse when a stimulus appears on the screen. Experiments may last up to 1 hour. Participants can complete as many experiments as they wish. They can quit at any point.
