Quizplus · Accepted Answer

The question mentions that the participants experienced partial sleep deprivation, meaning they did not get a full night's sleep. The results show that their performance on cognitive measures declined gradually during the study, indicating that sleep deprivation was having an impact on their cognitive functioning. Option A is incorrect because it states that there was no decline in performance, which contradicts the information provided. Option C is incorrect because the study only measured mood at the end, not cognitive performance. Option D is also incorrect because the study did not measure irritability weeks after the study.
