Probabilistic association learning



We are recruiting healthy adults between 18 and 45 years of age to take part in a study of the relationship among probabilistic association learning (a type of non-conscious learning), schizotypal personality traits (involving odd behaviours and/or beliefs in some people), striatal function (an area deep inside the brain shown to be important for this type of non-conscious learning) and genes important to striatal function.

All participants will be asked to complete (within two hours) three questionnaires, a computerized learning test, six brief “pencil and paper” cognitive tests and to provide a blood sample for genetic analysis. Some participants (based on their questionnaire scores) will be asked to come back to receive a functional magnetic resonance image scan of the brain.

Reimbursement of $20.00 per visit will be provided for your time and for out-of-pocket expenses.

If you have any questions or are interested in participating, please feel free to contact the research team.

'I've got the best job for you dad. Your shaky arm will be perfect for it!'

Children… honest and insightful. Their innocence warms the heart. But what words do you use to explain to a child that daddy has an incurable brain disease? What words tell them that in time he may not be able to play football in the park, let alone feed himself? What words help them understand that in the later stages, dementia may also strike? Aged just 36, this was the reality that faced Steve Hartley. Parkinson's disease didn't care he was a fit, healthy, a young dad and devoted husband. It also didn't seem to care his family had no history of it. The key to defeating Parkinson's disease is early intervention, and thanks to a global research team, led by NeuRA, we're pleased to announce that early intervention may be possible. Your support, alongside national and international foundations Shake it Up Australia and the Michael J Fox Foundation, researchers have discovered that a special protein, found in people with a family history of the disease increases prior to Parkinson’s symptoms developing. This is an incredible step forward, because it means that drug therapies, aimed at blocking the increase in the protein, can be administered much earlier – even before symptoms strike. The next step is to understand when to give the drug therapies and which people will most benefit from it. But we need your help. A gift today will support vital research and in time help medical professionals around the world treat Parkinson’s disease sooner, with much better health outcomes. Thank you, in advance, for your support.
