Flashing random images consecutively on one slide

[Michiel Spape]

Hi Suli,
Once again! 
Further on, if you like to use a nested list (with an attribute, say, myImages, filled with all the possible images), one way forward is to use the colon to select a specific row from your nested list. 
1. Make sure your nested list contains all the images, and is set to randomise with every trial
2. Have a trialList (with reference to nested list) with 5 attributes: Image1, Image2...Image5. Each level refers to myImages:1, myImages:2.. myImages:5. 
3. In the trialProc, have 5 slides, have 5 images on them (one each, obviously), let each refer to [Image1], [Image2]..[Image5]. 
So, e-prime randomises the order of your nested list. Your trial shows 5 images. Image1 will refer to myImages:1 - the first 'row' in myImages. Since your nested list is resorted every trial, however, the first row is always different.

This trick is explained elsewhere on this list under rapid serial visual presentation or the attentional blink.
Best,
Mich

Subject: Flashing random images consecutively on one slide

Hello Group,

I need help trying to set up a "distractor" slide that flashes 4-5
images at random for 1 second, each image for about ca. 200-250 ms
respectively.

So far, I tried setting up 4 consecutive slides with an image object,
each of which drawing the images randomly from a nested list, but it
seems that each of those slides always draw on the same image, so it
doesn't appear to be changing at all. (Or at least that's my
interpretation why I keep seeing only one image.)

Do any of you have any ideas?

Suli
