2.4.2 Add instructions to Fixation and Probe displays
Add instructions to the Fixation and Probe objects in the form of constant text (i.e., it will not vary
from trial to trial). Open the Fixation object, add four blank lines following the fixation character,
and type the text, as in the display below, to remind the subject of the response keys. Open the
Probe object and set the height of the display area (Frame tab) to 25%. This reduces the
displayed area to 25% in the center of the screen. These settings will permit the stimulus to
overwrite the fixation, but will not erase the response instructions.
2.4.3 Add Prime
Add a TextDisplay object following the Fixation object in the TrialProc, and rename this object
“Prime.”
Open the Prime object and type “[PrimeType]” into the Text field (i.e., the prime text will be
entered as an attribute value), as below. Set the duration for the Prime object to 1000ms, and do
not enable input.
