In this unit students explore the demand for sleep and the influences of sleep on mental wellbeing. They consider how changes to a person’s sleep-wake cycle can affect psychological functioning. Students explore the concept of mental wellbeing, including social and emotional wellbeing as a multidimensional and holistic framework. They apply a biopsychosocial approach to specific phobia, exploring how biological, psychological and social factors are involved in its development and management. A student-designed scientific investigation involving the generation of primary data related to mental processes and mental wellbeing is undertaken in either Unit 3 or Unit 4 or across both Units 3 and 4, and is assessed in Outcome 3 of this unit.
