Timeout Keyword
<Timeout N1>
<t N1>
<Timeout
designator>
<t
designator>
counter designators:
counter.name.
c.name.
counterN2
cN2
T parameter and switch alternative.
Sets the subject response timeout in milliseconds to
N1
or the keyword version can take the value of the designated counter (be it named
with
.name. or numbered with
N2) at item parsing time, default value is 4000ms. Note that this keyword's
format is a little different from other keywords that allow you to specify a
counter for their parameter as here classic
numbered counters are only legal with a
c or counter
before the number as a stand alone number by itself is a literal timeout value
in milliseconds, not a counter number.
The ability to use a counter exists primarily to facilitate fixed
time experiments where the subject only gets a certain time to respond to as
many items as they can:
