Sequences experiment

[Julia Fernandez]

I'm an E-Prime newbie designing an artificial grammar experiment for my final Master's project. In this experiment, subjects see a string of symbols and have to recreate the sequence using an SR box marked with matching symbols, i.e. a subject could see a string of a circle, a diamond shape and a poundsign and need to press the corresponding buttons. In the program, this would be represented as numbers ("1" for a circle + "4" for diamond + "5" for a poundsign).

 

I got everything up and running but hit a wall.  The sequences are of different lengths, 3-6 digits.  I changed the max allowable to 6 so now Eprime only accepts strings of 6 digits.  If you correctly enter a 6-digit string then it gives a "correct" screen.  If you have a shorter sequence, Eprime won't accept it until you add additional digits and then, of course, it's marked incorrect.

 

Can anyone help?

 

Thanks,

Julia
