Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The "d2 test of attention" has been used in studies regarding sleep deprivation due to night shifts in hospital staff, in order to determine whether sleep deprivation has an impact on performance. However, by repeating the test there appears to be a test-retest effect, as the participants improve when performing the test more than once. The aim of this study is to determine, whether the "d2 test of attention" has a test-retest effect.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

20 surgeons and 20 surgical nurses will be included in this study. They will be asked, after thorough instruction, to perform the d2 test of attention after a designed schedule. The participants will on day 1 and 2 perform the test 3 times consecutively at intervals of 5 minutes. On day 3, 4 and 5 the test will be repeated only once. After the 5th day follows a 7-day-break. On day 13 the test will again be performed once.
