About semi randomized Continuous Performans Test (Please Sebastiaan)

mmrn

I am sory. I asked this question but I couldn't understand because I don't know programming language.(http://www.cogsci.nl/forum/index.php?p=/discussion/1287/how-can-i-cptcontinuous-performance-test-as-semi-random#Item_1) I have tryed to learn since I asked that question. But I couldn't understand this language in the answers. May be you say that I must learn this. I have to execute my thesis, it's my last term. Please Sebastiaan, could you explain how ı can do this experiment clearly?

My problem: I try to conduct CPT test. İt have to be semi random. In this test, letters are presented 160 ms(there are 800 ms interval between letters).The participants should press the spacebar when see each"A"s following "Z"s. I want to present 300 stimuli, 50 of them must be A following Z, 50 of them any letter following Z. But they must be random.

I'm afraid I'm going to refer you back to the original discussion, where Eduard has given you a lot of help. If the answer is not as easy as you'd like, that's probably because the question is not trivial. Feel free to ask further questions in the original discussion though.
