Hi there, may I find out if it is possible to display summary feedback for participant for every block in the IAT script?

What summary information do you want to display?
I would like to display percent correct or number of correct responses for each block. 

Then the answer is yes, you can absolutely do that

Thank you. May I get some guidance on how to include this?

Have you already worked through the IAT code? If not, you'll want to do that first.

This is the script I have.

I did not ask you whether you have a script. I asked you whether you've familiarized yourself with the code and how it works. If so, you should already have a decent idea of at least one way to implement block-wise feedback. It could be done in much the same way the overall summary feedback works in the script,

One simple way is to just define a feedback instruction <page> for each block, present that via the block's /postinstructions, and apply the percentcorrect() function inline to the trials run by the respective block.

<page attributepracticefeedback>
^You got <%percentcorrect(trial.attributeA, trial.attributeB)%>% correct.
</page>

<block attributepractice>
/ postinstructions = (attributepracticefeedback)
/ bgstim = (attributeAleft, attributeBright)
/ trials = [
        1=instructions;
        2-17 = random(attributeA, attributeB);
]
/ errormessage = true(error,200)
/ responsemode = correct
</block>

I have added the editable instruction section: 
<page attributepracticefeedback>
^You got <%percentcorrect(trial.attributeA, trial.attributeB)%>% correct.
</page>

and added this to the blocks:
/ postinstructions = (attributepracticefeedback)

However, the page displayed is blank. May I find out how to resolve this?

Check your settings for /screencolor and /txcolor in the <instruct> element and make sure they're different. You won't see black text against black screen color, or white text against white screen color.

Thanks Dave! It works now.
