Hi,
at the moment I’m tryingto program the Stroop Task with the help of Inquisit. I used the Stroop Task scriptsin the Inquisit library as a basis, but I changed some elements. The problem isas follows:
I want to show the coloredwords only for 2000 ms. But the window center for participants to respondshouldn’t be restricted. Participants should have the possibility to answereven if the stimulus has disappeared. This is an example for a trial I programmed:
<trialredincongruentblue>
/ pretrialpause = 1500
/ stimulustimes = [0 =fixation; 500 = empty; 500 = redincongruentblue, redreminder, greenreminder,bluereminder, yellowreminder; 2500 = empty; 2500 = redreminder, greenreminder,bluereminder, yellowreminder]
/ correctresponse =("j")
/ validresponse =("d", "f", "j", "k")
/ responsetime = 500
</trial>
<text empty>
/items =("+")
/position = (50%, 50%)
/fontstyle =("Arial", 40%)
/txcolor = white
</text>
<textredincongruentblue>
/ items =("red")
/ color = blue
</text>
There is a fixationcross at the beginning of the trial, which is covered by a white cross after500ms. Simultaneously the stimulus and the reminders appear. After 2500 secondsthe stimulus is covered again by the white cross (disappears). The remindersremain.
The problem is thatthe stimulus disappears most of the time, but in some trials the stimulus doesn’tdisappear. I don’t know in which trials (the trials always change) and I don’tknow the reason for it. Can someone help me?
Thanks a lot!
