/ response = timeout(parameters.timeout)
/ validResponse = (" ", noResponse)

The following trial requires the subject to respond correctly (with the "a" key) in 1500 ms before moving on to the next trial:

<trial myTrial>
/ stimulusTimes = [0=myText]
/ response = timeout(1500)
/ validResponse = ("a", "b")
/ correctResponse = ("a")
</trial>
