[open] series of digits-one-by-one&multiple responses

reko

Hi opensesame dudes !
I am learning opensesame and I want to make an experiment in which 9 digits will be presented on the screen one by one in random order (different for every time) and then the participant will have to press the digits in the correct order of presentation.Is it possible to constuct such experiment without using inline script ?And if this is not possible, what is the most simple solution for a begginer ?!thanx a lot !

I also tried this script which i found in the forum

but the problem is that you should give an answer after each digit and i want to see all the digits and then answer. Also i dont know how to collect the answers.I used a "text-input" but i think this is not the best solution !

Hi,

Welcome to the forum!

It's a bit unclear to me what you want to do exactly. Your first post suggests that participants have to recall the digits after they have been presented, but your second post states that participants have to give a response immediately after each digit. Could you describe in more detail what kind of paradigm you want to implement exactly?

Cheers!

Hi Sebastiaan !Its ok !I have figure it out with the visual stimuli but now i cant make the same experiment with audio files. I want the participants to hear all the digits in random order and then answer. The problem is that i want each audio file played once for every loop and also that i want to be able to know whether the participant answered correctly or not.Is that clear to you ?I would appreciate any help

Hi Reko,

It sounds like you should be able to modify your previous experiment, so I would start from there. But your question could do with a lot more detail! What do you want to do exactly in terms of trial sequence, reponses, etc. What do you have so far, and what is still lacking?

Cheers,
Sebastiaan
