I have programmed an experiment in which I have 28 trials. This is an experiment for kids, and at the pilot it turned out that they get tired of it pretty quickly.
To keep them motivated, I would like to add a message halfway through the trials (so after 12 trials) saying someting like: "You are already half way done! Good job!".
I could of course make 2 blocks of 14 trials, but I don't know how to make it completely random then (so the trials are randomly distributed between the first and second block, and randomly distributed within blocks).
Is there an easy way to add such a message?
/ preinstructions=(micro_instruct_5 )
/ trials = [1-28=noreplace(tFear,tAngry,tHappy,tSad)]
/ ontrialbegin = [text.focus.textcolor = values.focuscolor]
</block>
