Hi All


Below you see the code for an experiment with 3 blocks of trials. Each trial selects a picture randomly from the same items list.


How can I get it to work like this:


Show one randomly selected picture with likert valence, then => show the same picture with likert arousal, then => show the same picture with likert opvallend (means: eye-cathing or noticeable), then => show another randomly selected picture, etc.


or alternatively:


Show one randomly selected picture with all three likerts in one page, then => show another randomly selected picture, etc.


Thx! Richard

Wow, perfect timing--I was having the same problem.  (Not only is Dave fast, he's telepathic!)
