Order of trials gets disrupted (case 411)

[vh2197]

Hi!

I programmed a study (attached is the .csv file) and it does a strange thing: at trial 4 (line 5) it jumps to one of the trials after 22 (I don't know which one because they're all the same -- randomizing from a pool of pictures). I have a suspicion that it has something to do with the asterisk, but I tried to play with it and it didn't work. If I divide the file to 2 (until trial 22) then everything works fine...Any ideas what might be going on?

Thanks!!
Valery.

Your .cvs file does not reveal any obvious causes of this unintended skip. Have you looked carefully at your IAPS_rand file? How many items are in that file? Are there errors or formatting irregularities that might lead to it being read as only having 4 items?

Since your .cvs file does not show any explicit command to skip, I would think something in your IAPS_rand file is indicating you're done after four trials; almost as if it thought you only had 4 items to choose from. But you have 20, correct?

Attaching that file would be helpful in replicating the error.
