Hi all,

Wondering if anyone knows how to edit this dot probe script to display both neutral and 50 threat/50 neutral trials so the same experiment administers test (48 50/50 trials) and training (288 neutral trials) ?

Thanks !
Hannah

You need to add the <trial> and other associated elements for the "neutral" category to the script and then sample from those trials per the <block>s' /trials attribute according to your needs. I.e.

<block DotProbeTask>
/ trials = [1-96 = noreplace(threat, neutral)]
</block>

would run 48 threat trials and 48 neutral trials in random order.
