A researcher is investigating the effect of a new cognitive training program on working memory capacity. They use a digit span test (recalling a sequence of numbers) to measure working memory. To ensure measurement validity, the MOST important consideration is:
Whether the digit span test yields consistent scores if administered repeatedly to the same individual.
Whether the digit span test accurately measures working memory capacity, and not some other cognitive function.
Whether the results of the digit span test can be generalized to other cognitive tasks.
Whether the digit span test is easy for participants to understand and complete.

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.
Students undertake a student-designed scientific investigation in either Unit 3 or Unit 4, or across both Units 3 and 4, related to mental processes and mental wellbeing. The investigation involves the generation of primary quantitative data. Students apply key science skills to develop and test a research question, gather and analyse data, and communicate findings in a structured scientific poster. A logbook is maintained for authentication and assessment purposes.
