I am trying to set up what feels like it should be a simple experiment that would have been very long winded in SuperLab 2 but should be a lot easier in version 4.
What I want is to display 6 letters of the alphabet on the screen for a short period and then ask the participant to enter which letters they saw.
The problems I’ve run into are:
Trial variables can’t be used to select what is displayed.
Variable lists can only be evaluated once per trial, so instead of having complete randomisation, I’ll need to have a variable list for each location and ensure there are plenty of trials to choose from which have sets of letters with no duplicates (I know there are some duplicates in the attached example, but that’s just because I’ve set them up quickly).
I tried to limit the number of trials in the block and neither the “When to Run” nor the macro seemed to work in 4.0.5. My macro does work in 4.0.6 except that I asked for 5 trials and I’m getting 7, which is worrying.
The text input box is visible during the presentation of the letters, but I only want it to be there after they dissappear.
Any help would be gratefully received. The actual experiment I want to set up will have more locations but if I can get this working I should be able to expand it as necessary.
Thanks in advance.
