ATI TEAS (Test of Essential Academic Skills) Version 7ReadingMedium
A student is researching the effects of sleep deprivation on cognitive function and finds a study abstract: "This meta-analysis synthesized data from 35 peer-reviewed studies (N=4,500 participants) investigating the impact of acute total sleep deprivation (TSD) on various cognitive domains. Results consistently demonstrated significant impairments across executive functions (e.g., working memory, decision-making, attention) and psychomotor vigilance. Effect sizes were moderate to large, with a dose-response relationship observed. Subgroup analysis indicated that the magnitude of impairment varied slightly by task complexity and individual resilience. Future research should explore long-term chronic sleep restriction and intervention strategies." Which of the following statements best summarizes the main conclusion of the abstract?
- AIndividual resilience is the primary factor in determining cognitive impairment from sleep deprivation.
- BFuture research should focus on chronic sleep restriction and intervention strategies.
- CTask complexity has a greater impact on cognitive function than sleep deprivation.
- DAcute total sleep deprivation significantly impairs executive functions and psychomotor vigilance.
Show answer & explanationAnswer & explanation
Correct answer: D. Acute total sleep deprivation significantly impairs executive functions and psychomotor vigilance.
The abstract clearly states that 'Results consistently demonstrated significant impairments across executive functions... and psychomotor vigilance,' which is the core finding presented.
Why the other options are wrong
- A. While individual resilience is mentioned, the abstract states impairment 'varied slightly' by it, not that it's the 'primary factor'. The main conclusion is about the impairment itself.
- B. This is a recommendation for future research, not the main conclusion drawn from the current study's findings.
- C. The abstract states impairment 'varied slightly by task complexity,' implying task complexity modulates the impairment, not that it has a greater impact than sleep deprivation itself.
