A study compares the cognitive performance of participants after 24 hours of sleep deprivation to participants with varying blood alcohol concentrations (BAC). Based on established research, which of the following statements most accurately reflects the expected cognitive effects?
Participants deprived of sleep for 24 hours will exhibit cognitive impairments roughly equivalent to a BAC of 0.02, primarily affecting complex decision-making.
Participants deprived of sleep for 24 hours will exhibit cognitive impairments roughly equivalent to a BAC of 0.10, significantly impairing reaction time and attention.
Participants deprived of sleep for 24 hours will show only minor cognitive differences compared to a sober control group, with minimal impact on memory recall.
Participants deprived of sleep for 24 hours will demonstrate cognitive deficits primarily in emotional processing, similar to the affective effects observed at a BAC of 0.05.

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.
In this area of study students focus on sleep as a naturally occurring altered state of consciousness and the demands for sleep across the life span. They examine REM and NREM sleep, biological mechanisms of the sleep-wake cycle, and how partial or total sleep deprivation can affect psychological functioning. Students compare the effects of full sleep deprivation with blood alcohol concentration and explore circadian rhythm disorders. They consider ways to improve sleep hygiene and mental wellbeing.
the effects of partial sleep deprivation (inadequate sleep either in quantity or quality) on a person’s affective, behavioural and cognitive functioning, and the affective and cognitive effects of one night of full sleep deprivation as a comparison to blood alcohol concentration readings of 0.05 and 0.10
