The study objective is to assess whether a learning effect, time of day, and the occasion of napping in between tests could influence SART results.

Outcome measures
Primary outcome
SART error score.
Secondary outcome
Errors of commission and omission
Subdividing total error score into errors of commission and errors of omission
is important, as these error types could reflect different cognitive processes.
Reaction time data (mean reaction time, coefficient of variation)
Measuring reaction time data is important because of the so-called
speed-accuracy trade-off.
Background summary
The Sustained Attention to Response Task (SART) is computerized vigilance task,
taking 4:20 minutes to perform. Following a pilot study, the SART has been used
in various studies with slightly different study methods in the Leiden
University Medical Centre.
Results of these studies pose the question whether SART error score could
possibly be influenced by time of day or by the occasion of napping in between
tests, and whether there is still a brief learning effect in the first
SART-session.
Study objective
The study objective is to assess whether a learning effect, time of day, and
the occasion of napping in between tests could influence SART results.
Study design
Observational study in the Leiden University Medical Centre.
Study burden and risks
Time to proceed through the study is about two hours for each subject. Subjects
are free to do whatever they want in 70-90 minutes of these two hours, except
sleeping and going outside. The actual study time consists of two SART
sessions, and for half of the subjects also an MSLT-session. Eight EEG
electrodes measure the occurence of sleep during the two hours of this study.
The study does not hurt, takes little time, and does not carry any risks for
the participant.
