Investigating the Impacts of Early Life Experience on the Brain & Behaviour

Step 1: Telephone/Video screening call (20 minutes) The first part of this study is a brief telephone/video call during which you will: * Be asked questions to check whether you meet the study eligibility criteria. * Be asked questions about your medical history (including mental health) and use of psychiatric medication. Step 2: ONLINE PARTS OF THE STUDY (3 hours) Once you have completed the online consent form you will be emailed a link to the online parts of the study. * You will be asked to fill in three online questionnaires which take around 30 minutes each and collect information about your demographics (e.g., sex, job, ethnicity, income etc.,), medical history, mental health conditions (e.g., autism spectrum quotient (you may opt of this questionnaire), depression, anxiety, addiction, drug and alcohol use) and personality traits (e.g., impulsivity, attachment, neuroticism, extraversion). * You will be asked to complete online games which are designed to assess memory, impulsivity, attention, face recognition and social interaction. These short tasks (5 - 10 minutes each) are similar to simple "brain training" games you may have seen online. They will take around 1.5 hours to complete in total. Step 3: FACE-TO-FACE PARTS OF THE STUDY (2-hours) BRAIN SCAN (1.5 hours) * When you arrive, you will be asked to review this study information sheet and sign a paper consent form and other safety/screening forms required for the study. * You will then be asked to take part in a magnetic resonance imaging (MRI) brain scan. You will be asked to lie down in a strong magnetic field for an hour whilst a computer takes pictures of your brain, and you complete short cognitive tasks (3 x 10 minutes each) and a resting state brain scan (10 minutes). BLOOD TEST (30 minutes) We would also like to collect a blood sample from you, as this will help us understand how early life events can impact your white blood cells which are a key part of your immune system. Step 4: INTERVIEWS, QUESTIONNAIRES \& MEMORY GAME (1.5 - 3 hours) You can choose to do the following parts of the study either when you visit the University of Manchester or during a remote session (Zoom/telephone). * The researcher will conduct interviews about your mental health history and your experience of friendships and relationships (up 2.5 hours). * You will be asked to complete a short, anonymised questionnaires about your experience of trauma and stress in your childhood including the Childhood Trauma Questionnaire and the Adverse Childhood Experiences questionnaire (15 minutes). * You will complete a short emotional memory game (on the researchers' laptop or via your computer if via Zoom) (5 minutes).
