    About the program

    In many situations, it is beneficial to think twice before we say something or take action. We all differ in how easily we are able to do this. For people who are naturally very impulsive, thinking twice before acting can be difficult. This can lead to fun new experiences, but it can also cause unpleasant or risky situations, for example when blurting out an impolite thought or losing money after making a reckless bet. When impulsivity gets very strong it also plays a role in several neuropsychological conditions, such as ADHD, addictions, and obsessive compulsive disorder.

    There are very few strategies available to help resist impulsive urges. One strategy that shows potential is a gentle painless form of brain stimulation called HD-tDCS (High Definition-transcranial Direct Current Stimulation). HD-tDCS involves delivering gentle electrical currents to the brain by placing electrodes on the scalp. A single session of HD-tDCS can produce a brief change in brain activity and may help enhance our self-control over impulsive urges.

    In this study we are investigating whether HD-tDCS over a brain area related to self-control, changes how strong peoples impulsive urges are. We will investigate this by delivering two different kinds of HD-tDCS over two separate research sessions. At each session, before and after the HD-tDCS, we will also measure brain activity with EEG during two computerised behaviour control activities.

    Who can join?

    We’re looking for volunteers who:

    • are aged between 18 - 55 years

    • are right-handed

    What's involved?

    Participation will involve:

    • attending two research sessions of three hours at Monash Biomedical Imaging in Clayton, during which you will:

    • complete questionnaires, an interview, and several cognitive activities
    • complete two EEG recordings of brain waves during the cognitive activities
    • complete two sessions of painless non-invasive brain stimulation

    Get started!

    To find out if this study is the right fit for you, we need to ask you some brief questions about impulsivity and your mental and physical health history. Your answers are strictly confidential and you will not be asked to provide your name or any identifying information until the end.

    The survey will take approximately five minutes to complete.
