Randomize across and within blocks

[lilyokc]

Hi Jeremy,

I’m trying to present my data in a few blocks with randomized block order. I used the code you gave in this thread to do that. However, I cannot figure out a way to modify the code such that within-block order is also randomized, which is what I want. Is there a way to do that?

Thank you so much for your help!

Hi,

Use randomize("label") to get a randomized series of trials labeled “label” where you would just use "label" to get a non-randomize series:

PennController.ResetPrefix(null)

var blocks = [randomize("block1"),randomize("block2"),randomize("block3"),randomize("block4")];
fisherYates(blocks);

Sequence("training", ...blocks)
