reaction time
The span of time that passes between the occurrence of a stimulus and the reaction that follows. The term is used in psychology, sports, and traffic-related contexts.
Müdigkeit kann die Reaktionszeit eines Autofahrers gefährlich verlangsamen.
Fatigue can dangerously slow a driver's reaction time.
The word is a clear compound of 'Reaktion' (reaction), the linking '-s-', and 'Zeit' (time). So it literally describes the time needed for a reaction.
Bei dem Test wird die Reaktionszeit der Teilnehmer gemessen.
In the test, the participants' reaction time is measured.
A reaction time can be 'kurz' (short) or 'lang' (long). It is often 'beeinflusst' (influenced), 'verlängert' (increased / lengthened), or 'verkürzt' (reduced / shortened) by external factors. You can also 'messen' (measure) or 'testen' (test) it.
Alkohol verlängert die Reaktionszeit erheblich.

The term is used especially often in the context of road traffic. Here, a short reaction time is crucial in order to avoid accidents.
