Hello,

I have a question concerning the SRC.

I want to create practice trials and experimental trials with different pictures. 
In attachment you can find my script so far.

There the values "practice" refer to the practice trials and the values "experimental_trial" refer to the experimental trials.

There should be 8 practise trials and 32 experimental trials for each block. In the practice trial should only appear the pictures: "orange_sqaure_1.jpg", "orange_square_2.jpg", "green_sqaure_1.jpg" and "green_square_2.jpg", but no one of the pictures of the trays. The picture should appear in random order.
In the experimental trials should only appear the pictures of the trays. They should also appear in random order.

When I run through my momentary script there also appear pictures of the trays in the practice trials and pictures of the squares in the experimental trials.

So how can I do that, that the pictures of the squares appear only in the practice trials and the pictures of the trays appear only in the experimental trials?

I hope you can understand what I mean and can help me to solve my problem.


Thank you very much in advance.

C.
