Influence of Cognition and Physiological Function by Partial Sleep Deprivation

• Grasp strength(kilogram)[ Time Frame: Change from baseline grasp strength at 2 months ]
  We use Jamar hand dynamometer (Jackson, MI, USA) devices to evaluate dominant hand grasp strength(kg) of the participants in standing position, forearm neutral. Each participants perform 3 attempts maximal isometric muscle contractions, and we will choose the best one as our outcome. Baseline evaluation will conducted on two weeks after all midterm exams completed and at least two months before the final exams starts. Outcome measurement will be on the first day after all final exams subjects complete.
• Single N-back test(correct rate, %)[ Time Frame: Change from baseline correct rate at 2 months ]
  We use single n-back test to evaluate working memory function and attention. We will provide computer devices for our participants. Participants will perform 3 same tasks, each task spend 1 minutes. We use the average percentage of correct rate as our outcome. Baseline evaluation will conducted on two weeks after all midterm exams completed and at least two months before the final exams starts. Outcome measurement will be on the first day after all final exams subjects complete.
• Stroop effects(seconds)[ Time Frame: Change from baseline performance(seconds) at 2 months ]
  Stroop effects is widely used to evaluate attention, executive function, inhibition process, and automatic responses. We provide standard stroop charts(Traditional Chinese version) for our participants, which include 4 small parts in this charts. We record the time(seconds) of each parts that participant needs to complete as our outcome. Baseline evaluation will conducted on two weeks after all midterm exams completed and at least two months before the final exams starts. Outcome measurement will be on the first day after all final exams subjects complete.

Partial sleep deprivation (PSD), is a common problem among current university students in Taiwan. Students often get inadequate sleep time due to burden schoolwork during exam period. In recent years, Issue of sleep quality has gradually been emphasized. According to previous research, lacking in sleep easily results in sleepiness, fatigue, and poor problem-solving performance. Sleep deprivation may also affects cognitive performance, like reducing working memory performance. Furthermore, sleep deprivation will probably alter autonomic nervous function, such as sympathetic/parasympathetic activity change. Previous researches also suggested that sleep deprivation may associated with the risk of being obesity or suffering from diabetes. However, most researches focused on the effects of total sleep deprivation, especially those who usually have night shift work, such as medical staff. Few studies investigated the cognitive function and physiological function of university students after a period of time of partial sleep deprivation. As a results, the aim of the study is to investigate how partial sleep deprivation affects the cognitive performance and physiological function before and after the final exam period in healthy young university students between 20 and 30 years old in Taiwan, in order to promote the importance of healthy sleep and improve sleep quality among university students.
