Like the BlockInstructions, the Introduction object instructs the subject to press the spacebar to
continue. In the properties for the Introduction object, 1) set the Duration equal to “-1” to wait until
a response is entered, 2) set the Input Mask to allow keyboard input, 3) set the Allowable field as
the spacebar (i.e., {SPACE}), and 4) set the End Action to “Terminate” upon response from the
subject. In the Properties for the Goodbye object, set the Duration to 5000. No input need be
enabled for the Goodbye object; it will simply time-out at the end of the duration.
2.6.5 Modify TrialProc to use PrimeDuration
To alter the duration of the prime, set the Duration of the Prime display based on the value of the
PrimeDuration attribute defined at the block level. Double click the Prime object in the TrialProc
to open it in the Workspace. Click the Property pages button to open the Property pages for the
Prime object, and select the Duration/Input tab. Refer to the [PrimeDuration] attribute in the
Duration field. This will vary the duration of the Prime display across blocks based on the block
level attribute.
