[open] Moving words and mouse response

ahanif

HI all,

I am a novice user of OpenSesame and am trying to make an experiment where I can show multiple words on the screen and expect the participant to click on as many words as they want in 5 seconds. I am sure that there might be a much efficient way to present multiple words in different locations as compared to the way that I have done (I have a pastebin link for that screen where I am trying to display different words in different locations ). The display screen also disappears after first mouse click, which is not what I want.I also want to specify start location and end location for the words so that they move on the screen.
Specifically, here is what I want to achieve:
Present multiple words on the screen.
Words should move around the screen for 5 seconds. (This part is most tricky for me)
Participants click on the words with the help of the mouse.
I wish to record the RT and accuracy of the clicks.

Thanks,
Asma

Here is the pastebin link again. It didn't show up last time

Hi Asma,

If I understand correctly, you want to have a dynamic stimulus display, in which five words move around the display for five seconds. At the same time, the participant can freely click anywhere on the display as many times as he/ she wants. Is that about right?

This will be a relatively tricky experiment to implement, and will certainly require inline scripting. As a first step, I would describe the paradigm in more detail, because right now it's a bit vague. What exactly should the display and the movement look like? I.e. is it smooth or do the words jump, is the movement unconstrained, etc. Once you have thought through all the details, you can start implementing the actual trial.

If you are not familiar with Python, here are some good links to get started:

Of course, if you have further questions, please don't hesitate to post them here. (But only once, not three times as you did now!)

Cheers,
Sebastiaan
