Project Description:

Project Description: We are looking for Healthy, Right-handed MALE Non-smokers between the ages of 23 to 27, who have never smoked regularly before.

You are invited to participate in a study that will examine the relationship between our ability to deliberately control or suppress our behaviour, and our sensitivity to reward (desire or motivation for a particular behaviour). The study utilises a go/no-go task under different conditions to examine the interplay of reward sensitivity, and inhibition control, and whether differences in behaviour are reflected in brain activity differences measured with magnetic resonance imaging (MRI).

There are two sessions involved. The first session takes place at the University of Melbourne, Parkville, and will involve you making simple judgments on a series of images displayed on a computer screen. In the second session, you will do this task inside a MRI scanner while we take images of your brain at the MRI scanner based within the Royal Children's Hospital. To assess eligibility for the study, we will also ask you to complete questionnaires about your drug use behaviour, as well as current and past medical and psychiatric history.

You will be reimbursed $20 per hour for your time and additional payment commensurate with performance on tasks providing monetary rewards.Please note that participants will need to attend a session on the 1st of March 12 noon, OR 3rd of March, 1:45pm.

MRI Brain Imaging:MRI is a standard non-invasive procedure for taking images of the brain and has no known risks for people who have no metal in their body.

This experiment follows the guidelines of the National Health and Medical Research Council statement on human experimentation, and adheres to the ethical review process of the University of Melbourne.For further information, or to volunteer to take part in the study,contact:
