Thanks, Jeremy! I’m just getting back to this after working on some other stuff. I can no longer see the demo experiment you posted because it uses DashedSentence, but I’ve tried to implement your suggestions and it seems like it is mostly working with the new PennController.js. The only issue is that there is no “Redo” button. The only thing I see at the end of the practice trial is the “Proceed” button. How can I add a “Redo” button so that they could redo the practice trial if they want to. Thanks in advance!

Thanks, Jeremy. Removing the superfluous once did not fix the issue, but adding a Timer element did. As always, thank you so much for your help. I really appreciate it!

Thanks for this suggestion, Jeremy! I had forgotten about the callback method. However, after trying this, all of my recordings now seem to be empty. The zip files are saved to my server, but when I unzip them I get the following error (using the command line utility unzip on macOS: warning [uploads/ef29bba9-9e2c-3325-5b27-5ee7bff1179a.zip]: zipfile is empty Any idea why that might be the case?

I just created an account with the new farm.pcibex.net and moved things to there, and it does seem to be working.

[adamliter]

Hmm, that’s interesting. I do have "trials" in the Sequence command. I’ve pasted the full code below. I do still have this on expt.pcibex.net, not farm.pcibex.net, and I noticed the version of PennController I have is 1.8-dev, whereas it looks like the PennController version on farm.pcibex.net is 1.9. Could that be the issue?

Sorry, I have another followup question. 🙂

I’m currently trying to use newController with the AcceptabilityJudgment and Question controllers from Ibex, but nothing shows up on the screen. I also don’t see any errors with the debugger. Do you have any idea what might be going on? Here’s what I have:

PennController.Template("final_pilot_03_cnp_subj_items_all_lists.csv",
    row => PennController("trials",
        defaultText
            .settings.center()
            .print()
        ,
        newController("AcceptabilityJudgment", {s: row.Sentence, as: ["1", "2", "3", "4", "5", "6", "7"], presentAsScale: true, leftComment: "very bad", rightComment: "very good"})
            .print()
            .log()
            .wait()
            .remove()
        ,
        (row.Question != "NA" ?
            newController("Question", {s: row.Question, as: ["Yes", "No"], hasCorrect: row.Answer})
                .print()
                .log()
                .wait()
                .remove()
        :
        {})
    )
    .log("ParticipantID", ParticipantID)
    .log("Group", row.Group)
    .log("UniqID", row.UniqID)
    .log("Sentence", '"' + row.Sentence + '"')
    .log("Question", '"' + row.Question + '"')
    .log("Answer", row.Answer)
);

Thanks! I did not know about the ability to inject controllers into PennController trials. Thanks for the reference, Jeremy

Hi Jeremy,

I have a followup question to this for a different experiment. Is it possible to use the syntax of “Template( row => ["label", "controllername", options, "controllername", options, ...] )” with both controllers from Ibex but also the newTrial/PennController command?

I’m trying to do an experiment where, in one trial, I (i) play an audio file, (ii) present a sentence using rapid serial visual presentation (RSVP), then (iii) have the participant type something in a text box, and finally (iv) collect a recording from them at the end of the trial. It seems like there are straightforward ways to do everything but the RSVP with PennController. I was thinking I could use the DashedSentence controller with the display set to “in place” from Ibex to do the RSVP, but I’m not sure if it’s possible to mix these things. Given the expected syntax, it doesn’t seem like Template(row => ["trials", newTrial("trial-begin", newAudio("trial-begin", "trial-begin.mp3")), {}, DashedSentence, {s: row.sentence}, ... ]); unfortunately. Am I correct in thinking this won’t work? If not, do you have any suggestions for a good way to do this? Maybe it’s easier to do RSVP of a full sentence with just PCIbex than I think. Thanks again in advance for your time!

[adamliter]

Thanks Jeremy! I really appreciate it. That seems to be working well.

[adamliter]

Thanks Jeremy! I really appreciate how quick you always are to respond. 🙂

I have a (hopefully) quick followup question. I’m trying to access the value of “ParticipantID” inside of a newText element. I know this is possible by calling something like .after.text(getVar(...)) and .before.text(getVar(...)) on the newText element, but I’d rather not do this because it inserts a bunch of CSS around the element. I want something like this, but this currently returns undefined rather than the actual value of “ParticipantID”:

PennController("exit",
    defaultText
        .print()
    ,
    newText("code", "<p>Your unique identifying code is: ".concat(getVar("ParticipantID").value, "</p>"))
    
);

[adamliter]

It seems I misunderstood the b64_md5 algorithm. What I really wanted was this:

PennController("consent",
    newVar("ParticipantID", b64_md5((Date.now() + Math.random()).toString()))
        .global()
...

[adamliter]

Hi Jeremy,

Thanks for your quick response as always. Yes, just deleting the "qst" label gives me the result that I was trying to achieve. I really appreciate your help. Thank you!

[adamliter]

Thanks, Jeremy. I really appreciate it. Don’t worry too much about finding a hack. It’s easy enough to add the information back in during the data analysis, since the sentence itself is recorded, but it would be nice if it were possible to log additional information somehow.

[adamliter]

Ah, thanks, Jeremy! I really appreciate the quick response.

[adamliter]

Ah, thanks! I should have thought to try that. That works perfectly.
