Effects of mood disorders on electrophysiological measures of central executive and emotional processing in adolescents: an ERP study

Childhood and adolescence are very important periods for brain development, and are linked to  changes in intellectual and emotional functions. Distractibility is likely to cause concentration  difficulties and affect performance at school, both of which often happen in children and  adolescents with depression. This study aims to better understand brain processes involved in attention,  higher thinking skills, and emotional processing in children, adolescents and young adults with and without depression.

This study involves a visit of about 3 hours and 20 minutes in our laboratory during which you will be asked to provide a saliva sample to screen for street drugs, fill out some questionnaires about your mood, sleep, behaviour, and thoughts, and we will record the electrical activity of your brain (electroencephalography, EEG) while we will ask you to perform simple tasks on a computer. You will receive a financial compensation of 40$ for completing this study.
