Hello,
I'm trying to program a dot probe study and am having some difficulties with the display times.
For starters, is there a way to keep the probe displayed until the participants input a response? Or, is there a way to modify the display time of the probe? Should I be using a "stimulus timeout" command to accomplish this? Currently I'm using the dot probe template and I'm finding that the probe disappears too quickly.
Similarly, I would like to adjust the stimuli display time so that it disappears after 500ms, instead of the preset of 1500ms. However, when I change the setting from 1500 to 500, the stimuli don't seem to appear at all.
Here is my presentation script if it helps:
<trial pleasantleft>
/ correctresponse = ("e")
/ validresponse = ("e", "i")
/ stimulustimes = [0=fixation; 500=erasefixation, pleasantleft, unpleasantright; 1500=erasewords, probeleft]
</trial>
Many thanks.
Marguerite
