In the same way you provide the per-block feedback. Set up <values>, <text>, <trial> and <block> elements displaying the relevant metrics and run the resulting block after your 3 game blocks.

Hi Dave,

I corrected the calculations and managed to provide paricipants with a block feedback about their score. Now I would like them to receive also a feedback page that  informs them about the total number of points won across the 3 blocks. How can I achieve this? Thank you.

**********  blocks ****************************

<block test_gametask1>
/ screencolor = (0,0,0)
/ preinstructions = (testfase_gametask1)
/ trials = [1-12 = random (CSneu, CSpun); 13 = feedback]
/ blockfeedback = (meanlatency)
</block>

<block test_gametask2>
/ screencolor = (0,0,0)
/ preinstructions = (testfase_gametask2)
/ trials = [1-12 = random (CSneu, CSpun); 13 = feedback]
/ blockfeedback = (meanlatency)
</block>

<block test_gametask3>
/ screencolor = (0,0,0)
/ preinstructions = (testfase_gametask3)
/ trials = [1-12 = random (CSneu, CSpun); 13 = feedback]
/ blockfeedback = (meanlatency)
</block>

It's not a matter of display. Your calculations must be wrong. Check them.

Hi again Dave,

Uff my happiness did not last long as I have just realized that the score displayed is the sum of scores for all trials, and not only for the trials when participants win 10 points as a result of their fast RTs. So if I run the 12-trial block, I end up with a score of -120, although I have just lost 20 points during the task (as displayed during the trial feedback). So what element shall I use so that the final score displayed sums up only my correct responses during the task and not all my responses? I would appreciate if you can point me in a direction and sorry for bothering you with my beginner questions.

Regards,

Ana

Perfect, I ran the task again and now it displays the score feedback :) Sure, I will study the tutorials more carefully. Thanks a lot for your guidance!

Ana

You've defined the /trials attribute twice. That's not allowed. The second definition has invalid syntax, too. See the docs for correct syntax examples.

The syntax here is also invalid. It should be

/ trials = [1-12 = random (CSneu, CSpun); 13 =  feedback]

obviously. I recommend you revisit the tutorials included in the Inquisit documentation to get more familiar the basic elements and their correct syntax.

Hi Dave,

Ok, so now I tried to define those elements according to your advice. If I include two trial attributes inside the block, I receive a warning saying that the trial attribute of the block element is unassigned and could not be located.

<values>
/ score=0
</values>

<text feedback>
/ items= ("value = <% values.score %>")
</text>

<trial feedback>
/ pretrialpause= 300
/ trialcode = "feedback"
/ responsemode = timeout (2500)
/ stimulustimes = [0=feedback]
/ responseinterrupt = trial
/ posttrialpause= 300
</trial>

**********  blocks *************************
<block intro_gametask>
/ screencolor = (0,0,0)
/ preinstructions = (intro_gametask)
/ trials = [1-12 = random (CSneu, CSpun)]
/ trials = [1 = (feedback)]
/ blockfeedback = (meanlatency, correct)
</block>

However, if I include the feedback inside the same trial attribute of the block (see below), the task plays BUT I do not get any feedback score page at the end of the block.

<block intro_gametask>
/ screencolor = (0,0,0)
/ preinstructions = (intro_gametask)
/ trials = [1-12 = random (CSneu, CSpun) feedback]
/ blockfeedback = (meanlatency, correct)
</block>

What important step am I missing? Thank you again.

Ana

This is presumably due to a typo somewhere in your script. Inspect the element the error message is thrown for.

This does not make sense. You don't want a <text> element to try and display a <block> element. You want the <text> element to display <%values.score%>, you want a <trial> to present said <text> element and a <block> to run said <trial>.

Hi Dave,

Thanks, I think I resolved the error feedback.

I have one more question: I defined values and used ontrialend in order to calculate how many points participants win during the task. But I get a message saying that ''value score'' is invalid.I have also defined a text score that is meant to be shown to participants at the end of the block, but I get a message that ''block_introgametask is invalid''. Could you help me understand what is missing? My goal is to get inquisit count the +10 points delivered during the block and then show participants a total score feedback at the end of each block.Thank you again for your patience.

Ana

<values>
/ score=0
</values>

<trial CSrew>
/ pretrialpause= 700
/ trialcode = "CSpun"
/ validresponse = ("q", "s")
/ errormessage = (errormessage, 500)
/ iscorrectresponse = [trial.CSrew.response== "16"]
/ responsemode = timeout (1500)
/ stimulustimes = [0= kaderm, CSrew, CSrewS; 100 = eraserm, ?]
/ responseinterrupt = trial
/ posttrialpause= 700
/ branch=[if (trial.CSrew.meanlatency < 350) trial.points]
/ branch = [if (trial.CSrew.meanlatency > 350) trial.nopoints]
/ ontrialend=[values.score = values.score + 10 * trial.CSrew.correct]
/ ontrialend=[if (trial.CSrew.correct == 1) values.score = values.score + 10]
</trial>

<text score>
/ items = ("Total score: <% block_introgametask %>")
/ position = (50%, 5%)
</text

Here is a drastically stripped down version of your code:

<block myblock>
/ trials = [1-10=CSrew]
</block>

<trial CSrew>
/ trialcode = "CSrew"
/ validresponse = ("q", "s")
/ errormessage = (errormessage, 500)
/ iscorrectresponse = [trial.CSrew.response== "16"]
</trial>

<text errormessage>
/ items = ("ERROR")
</text>

Error messages work perfectly fine for me. If they do for you too with this code, you need to re-check your script for mistakes in other places.
