I would like to ask if anyone have already programmed "Siegler number line task" on OpenSesame?
And if so could you send it to me or can I talk to you?
I haven't, but if you give a little more detail on the task, I might be able to give you some pointers to a way of implementation.
I answered you on this discussion
Expyriment is shipped with a line bisection task as an example. see https://github.com/expyriment/expyriment-stash/blob/master/examples/line-bisection.py
