Hi there again!
Can I ask you for your advise?
I want to write an experiment with priming like this:
(80 milliseconds) Mask -> (12 milliseconds) Stimuli -> (80 milliseconds) Mask
I used "trialduration" to deteremine milliseconds for mask and stimuli as well. Need to say that after running it doesn't look like thing that I would like to have - an especially 12 milliseconds stimuli (I can see it without no additional effort).
Do I have my milliseconds corect?
BTW.
Is there's some way to randomise /hposition in picture element and then in MASK (shape element) get the exactly same value for /hposition?
--- A1 ---
<picture picture_A1>
/ items = ("XXX.jpg")
/ hposition = 15
/ vposition = 15
/size = (20%, 20%)
</picture>
<shape mascingA1>
/ shape = rectangle
/ size = (250, 250)
/ color = black
/ hposition = picture.picture_A1.hposition
/ vposition = picture.picture_A1.vposition
</shape>
--- A2 ---
<picture picture_A2>
/ items = ("XXX.jpg")
/ hposition = 80
/ vposition = 80
/size = (20%, 20%)
</picture>
<shape mascingA2>
/ shape = rectangle
/ size = (250, 250)
/ color = black
/ hposition = picture.picture_A2.hposition
/ vposition = picture.picture_A2.vposition
</shape>
<shape blank>
/ shape = rectangle
/ size = (250, 250)
