Social and Affective Neurodevelopment (SAND)
The Social and Affective Neurodevelopment group aims to characterise neurodevelopmental risk and resilience factors for common mental health problems in children and adolescents, particularly mental disorders such as depression and anxiety. An important aspect of the research is to incorporate a biopsychosocial approach, investigating whether and how a range of factors, particularly adverse environmental experience and puberty, influence and interact with neurodevelopment to confer risk for mental health problems.
Adolescence to emerging adulthood (A2EA) study
The A2EA Study is a prospective longitudinal study that aims to address core questions regarding biological and environmental risk factors for the development of depression and other psychopathologies with common onset during adolescence and emerging adulthood. The study began in 2003 and involved the recruitment of ~250 early adolescents, selected to be at varying levels of risk for psychopathology based on their temperament. Participants were comprehensively assessed at ages 12, 14, 16 and 19 years using a multi-method multi-source battery of validated measures of psychopathology, brain structure/function, temperament, family processes, genetics, endocrine function and family history of psychopathology. A final follow-up of participants' mental health and functioning in their mid-late twenties has recently been completed.
The emotional learning and memory (ELM) study
The broad aims of this study are to: 1) examine neural differences between children, adolescents, and adults during fear extinction; 2) examine how sex moderates fear extinction across development; and 3) examine how individual differences in trait anxiety and (gonadal and adrenal) hormones influence fear extinction and its neural correlates. The results of this project will contribute increased knowledge about: a) the neurodevelopmental and hormonal underpinnings of anxiety; and b) how and why some individuals are particularly prone to anxiety disorders. The results of this study will inform the development of more targeted and effective treatments of anxiety disorders in young people.
