2.0: Count Down Clock

Description

This sample experiment demonstrates how to display a count-down timer to the subject using InLine script after a stimulus has been displayed for a specified amount of time.

Abstract

The Stimulus object contains two SlideText sub-objects – one to display the stimulus, and another to display the countdown clock. The SlideText used to display the countdown clock is blank by default; its Text property will be set in the GetResponse InLine script if necessary.

The GetResponse script loops continuously until either the subject responds (determined using the IsPending method of the Stimulus object) or the Stimulus has been displayed for the desired maximum duration. Inside the loop, the script checks to see if the Stimulus has been displayed for over 5 seconds. If so, the Text property of the second Stimulus SlideText is changed to display the countdown clock.
