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.

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.

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!

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

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

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>

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

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.
