pseudorandom order of items
Hi,
My experiment consists of a practice loop and sequence in which the different objects (n=6) are introduced. After that the trial loop and sequence begin, in which the participant has to name 6x6 items in a fast way. But the items shouldn't be shown twice in immediate succession.
I've tried to solve the problem as Sebastiaan wrote it for Federica (http://forum.cogsci.nl/index.php?p=/discussion/80/solved-pseudorandom-order), but It doesn't work:
- I didn't get, where to create my pic_list. In the inline_script or do I have to define the pic_list in a block?
- Then I didn't understand, where I have to check, if a number or an object is repeated immediately!?
- In the debug window is written, that the name "shuffle" is not defined. Maybe I have to install something for that?
- In the second part "Then, at the start of a trial, you select one number and set a variable that you can use in, for example, a sketchpad, like so [my_pseudo_random_pic]. This assumes that you have named your images image01.png through image13.png." > I didn't get, where I have to set the variable and do I have to select a number of the image and write into the brackets "pic = pic_list.pop()"?
I'm sorry about all these questions and I hope, you could help me! You're doing a great job with the program and this forum!
Greetings

Hi Karin,
The discussion that you're referring to is quite outdated. Nowadays pseudorandomization is implemented in the
loopitem:I hope that gets you started!

The following problem "- In the debug window is written, that the name "shuffle" is not defined. Maybe I have to install something for that?" from above is solved...
Sorry, I didn't know this. Thank you!
When I write the command
constrain word maxrep=1
in the script of the loop, it shows a syntax error. What am I doing wrong?
I found the problem! So thank you for your help! It works now!
