Error messages - Learning Paradigm

Isabel — Thu, 19 Dec 2013 04:27:02 GMT

Hi Inquisit helpers,

I always programmed in Inquisit 4, but here (my internship, university abroad; in Italy) they use Inquisit 2.0...

I want to program a learning paradigm: participants will be presented some pictures (pictures of vegetabeles) along with two differerent questions (randomized): What is the name OR what is the characteristic of this vegetable? (refers to an earlier task).

What I want to program is the following:

1. when participants give the correct answer, they can continue to the next trial (which seems to work in the script)

2. when participants give the WRONG error an errormessage will appear ("RISPOSTA ERRATA, RIPROVA") (Italian) -> means: false answer, try again

Problem I face: at the moment the participants can continue whenever they give the correct answer (unlimited trials). However, what I want is that they can just try for max. two times. After two errors, I will let them show the correct answer "the correct answer is ...." and then continuing with the next trial. How can I program this in Inquisit 2.0?

3. At the moment the 'errormessage' remains on the screen until entering the correct answer. I would like the errormessage to disappear after a few ms. How can I program this. There is no timeout function in the <text> command.

Another problem I face is that the pictures of the vegetables are not shown on the screen. You may have some suggestions/things that I can check to resolve this problem?

** Pages Memory

Ora ti verrà chiesto di rispondere ad alcune semplici domande circa i nomi e gli aggettivi che hai memorizzato nell’esercizio precedente.

Cerca di commettere il minor numero di errori possibile. Dopo qualche errore ti verrà indicata la risposta corretta, in modo da aiutarti a memorizzare ulteriormente nomi ed aggettivi

</page>

Compito completato! Ora preparati alla seconda parte di questo esperimento.

I cannot say anything about those pictures. I don't have those files and neither do I have a system that would still run ancient Inquisit 2 (it doesn't work under current operating systems).

Regarding the previous questions re. limiting the number of (incorrect) responses participants are allowed to submit, look at something along the lines of

<block myblock>
/ trials = [1-2=noreplace(a,b)]
</block>
<trial a>
/ stimulusframes=[1=atext]
/ validresponse = (30, 48)
/ correctresponse = (30)
/ errormessage = true(errortext, 500)
/ correctmessage = true(correcttext, 500)
/ branch=(trial.a.errorcount, GE, 2, asolution)
/ branch=(trial.a.error, EQ, 1, a)
</trial>
<text atext>
/ items = ("A")
</text>
<trial asolution>
/ stimulusframes = [1=asolutiontext]
/ timeout = 3000
</trial>
<text asolutiontext>
/ items = ("The solution is A.")
</text>
<trial b>
/ stimulusframes=[1=btext]
/ validresponse = (30, 48)
/ correctresponse = (48)
/ errormessage = true(errortext, 500)
/ correctmessage = true(correcttext, 500)
/ branch=(trial.b.errorcount, GE, 2, bsolution)
/ branch=(trial.b.error, EQ, 1, b)
</trial>
<text btext>
/ items = ("B")
</text>
<trial bsolution>
/ stimulusframes = [1=bsolutiontext]
/ timeout = 3000
</trial>
<text bsolutiontext>
/ items = ("The solution is B.")
</text>
<text errortext>
/ items = ("Error")
</text>
<text correcttext>
/ items = ("Correct")
</text>

Hi Dave,

Thanks for your fast response. Inquisit 2.0 is really limited, I realized... So, probably it is better to change my higher-order demands :)

However, I hope you can answer my question about the pictures, since this is much more essential!

Best, Isabel

I don't think what you want can be done with Inquisit 2. You'd need at least Inquisit 3 and its much more elaborate mathematical and logical facilities.

The only option you have in Inquisit 2, is to use /branch to run dummy trials to serve as proxies for counting certain types of responses.

Clicked on the ENTER button before writing a proper ending, here it comes:

Thanks in advance! And hope you can help me.
