Several options depending on the *type* of RT feedback you want to display. What you probably want to do is simply add the already existing RTFeedback <text> element

<text RTfeedback>
/items = ("your speed: <%(trial.nocue2.sumlatency + trial.centercue2.totalsumlatency + trial.doublecue2.sumlatency + trial.spatialcue2.sumlatency)/(trial.centercue2.count + trial.nocue2.count + trial.doublecue2.count + trial.spatialcue2.count)%> ms")
/ fontstyle = ("Arial", 5%, false, false, false, false, 5, 1)
/position = (50%, 40%)
</text>

to the practice feedback <trial> element's /stimulusframes:

<trial practice_feedback>
/ontrialbegin = [if (values.validcorrect == 1) {text.feedback.textcolor = green; values.selectfeedback = 2} else {text.feedback.textcolor = red; values.selectfeedback = 1}]
/stimulusframes = [1 = fixation, feedback, rtfeedback]
/trialduration = values.practicefeedback_duration
/branch = [trial.iti]
/recorddata = false
</trial>

Hi Dave, thank you for your reply.
I have added the 'rtfeedback' in the space you suggested and it does show RT feedback in the practice trials when I run the script
However, the RT feedback that it provides is an average feedback of all previous trials. Is it possible to give RT feedback of each trial, rather than an average RT?
Thanks! Julia

Yes. If you only want to report the last individual latency, change <text rtfeedback> to

<text RTfeedback>
/items = ("your speed: <%block.ant_practice.latency%> ms")
...
</text>

Thanks Dave, that works perfectly.
