We are looking for participants in a study that investigates how the intake of a drug affects healthy volunteers making decisions for themselves, decisions that affect them and others, and their learning about others. To do so, we want to compare the effects of a single dose of a drug called Ritalin or a drug called Strattera to that of a placebo on computer tasks that measure decision-making and learning.

We are inviting young healthy volunteers, aged 18-35, who are: fluent in English, have no history of psychiatric/severe cognitive problems, and are non- or light smokers. We will reimburse you for your time and travel expenses. You will also have a chance to win additional money during the study.

If you are interested in participating in this study and/or would like further information, please contact
