randomizing the color of the text?

[victorialiu05]

I’m trying to implement an emotional Stroop effect experiment using PCI bex. This experiment requires me to randomize the colours (blue, red, green, purple) of each word presented to the participants. How can this randomization be implemented?

Hi,

If you are fine with total randomization, you can do something like this:

newTrial(
  newButton(['blue','red','green','purple'][Math.floor(Math.random()*4)])
    .css("color", ['blue','red','green','purple'][Math.floor(Math.random()*4)])
    .print()
    .wait()
)

Another option is to use pseudo-randomization by listing pre-generated color associations in a table and simply refer to the columns from inside Template
