Hi,

Your Sequence references the labels “test1” and “test2” when it should reference the labels “practice1” and “practice2”:

Sequence( "intro", "instructions", "test1", "test2", randomize("experiment"), randomize("part2"), randomize("part3"), SendResults() , "bye" );

You remove your Text element immediately after you print it (only printing a TextInput element in the meantime):

newText("Answer", "How far is this word from English?")
   .center()
   .print()
,
newTextInput("TextInput2")
   .center()
   .print()
,
getText("Answer")
    .remove()

In the lines that come just after, you create a new TextInput element that you named “TextInput2”, just like the one you create before, so PennController won’t know which one you mean when you use getTextInput("TextInput2") later on:

getTextInput("TextInput2")
    .remove()
,
newTextInput("TextInput2")

Hi Elias,

There are several different and somewhat advanced questions in your message, I won’t be able to fully address them at the moment. Maybe other users of the forums might be able to help you with them. In the meantime, let me give you pointers:

– The command GetTable().filter lets you subset your tables. You could add a column to your table where you number your items from 1 to 60 and use filter in three different Template commands to generate trials with formats specific to each block in phase 2

– You can use .substring(0,3) on a string to return just the three first characters, e.g. row.Word.substring(0,3). You can use the TextInput element to have people type in text, and the before/after commands to place the Text and TextInput next to each other, or place them on a Canvas element if you need more control on the visual layout

– The Audio element will let you play audio files (which you’ll need to upload to your project or to a host space first, of course). The tutorial illustrates how to use it

Hi Ana,

The numbers are not random, they match exactly the text from the table’s token column, eg:

3eak,beak-peak_1_VOT_1.wav,438
5eak,beak_peak_2_VOT_2.wav,438

Using a custom font is more involved than just uploading a font file to a project’s Resources folder. It requires using the @font-face CSS rule to fetch the font file. The PCIbex Farm won’t allow background access to the font file, it will result in a CORS error (you can, however, download it manually by directly entering the URL in the address bar, but that’s of no help here)

My suggestion is to upload the font file on a domain that won’t throw a CORS error and insert this in the project’s global_main.css file under the Aesthetics folder:

@font-face {
    font-family: "Arial Modified";
    src: url("https://url.toward.the/font.otf") format("opentype");
}
.PennController-wordtoken {
    font-family: "Arial Modified";
}

I should note, however, that the Arial font is not under an open license, which means you cannot modify it legally

Hi,

1) If you want the time between the sentence and the scale, you should place the newVar command before the second key press (the one just before the sentence appears) and the getVar command after the third key press (the one that precedes the scale appearing)

2) That “RT” column will only be included in the lines that correspond to that newTrial command. If you have lines in your results file coming from, say, intro/welcome/end/etc. trials, they won’t include an “RT” column because their corresponding newTrials don’t have the same .log command (because there’s no RT to compute for those trials). Is the RT column missing from the lines corresponding to the newTrial that was embedded in Template too?

3) You can find an example of how to analyze data in R in the advanced tutorial: in this example, reaction times are calculated post-hoc by subtracting event times coming from different lines from the same trial. Note that the table resulting from the piece of code below (copied from the tutorial page) follows the one-line/one-trial format that you seek:

tidied_results <- tidied_results %>%
  mutate(reaction_time = selection_time - canvas_time,
        correct = if_else(condition == selection, 1, 0))

You are using version 1.6 of PennController (not sure where you found it). Update to the latest version (currently 2.0)

Jeremy

[Jeremy]

Do you have a link to your experiment that I could check?

Jeremy

[Jeremy]

Hi Jones,

Did you include PennController.ResetPrefix(null) in your script? (it should be on the very first line)

Jeremy

[Jeremy]

Great! Just in case the problem recurs, you should know that I’m actively working on the next version of PennController. It is still work in progress, but you can find my most recent build here. I improved the way zip files are downloaded and resources are preloaded

Hi Jana,

You should always stop Recorder elements. Try adding getMediaRecorder(row.model+"-words").stop() after getText("instructions").remove() and getMediaRecorder(row.prompt+"-words").stop() after newButton("Done").center().print().wait().remove()

Hi Ana,

The shuffle command actually re-prints elements that were shuffled, which can cause glitches for elements positioned relatively to another element. My suggestion is to have the shuffle command executed early on when the Canvas element is hidden, and only reveal that element later. Here is a rewrite of one of your two Template commands:

Template( "TestWordList.csv" , row =>
  newTrial("block1",
    newText("fix", "+") // create a fixation cross
        .css("font-size","80px")
        .print("center at 50%" , "center at 50%")
        .log()
    ,
    newTimer("fixtime",300).log().start().wait() // present the fixation cross 
    ,
    getText("fix").remove() // remove the fixation cross
    ,
    newImage("pic", row.Image1)
        .size(200,200)
        .print("center at 50vw", "center at 50vh")
    ,
    newCanvas("words", 820, 820)
        .add("center at 35%", "middle at 38%", newText("1",row.Word1).css("font-size", "40px") )
        .add("center at 65%", "middle at 38%", newText("unrel",row.Unrelated).css("font-size", "40px") )
        .hidden()
        .center()
        .print()
    ,
    newSelector("words")
        .disableClicks()
        .add( getText("1") , getText("unrel") )
    	.shuffle()
        .keys("F", "J")
    	.log()
    	.disable()
    ,
    newTimer("pictime",1000).log().start().wait()
    ,
    getImage("pic").remove()
    ,
    newTimer(50).start().wait()
    ,
    getCanvas("words").visible()
    ,
    getSelector("words").enable().wait()
  )
)

Note that I name and log the Timer elements rather than the visual elements (which are now printed early on) and I moved the keys command below the shuffle one, because I presume you want to preserve the left-F/right-J association

Hello Marisol,

Here is a suggestion:

var n_question = 1;
Template("myTable.csv", row =>
  newTrial("experimento",
    newText("*").center().css("font.size", "x-large").print()
    ,
    newKey(" ").wait().log("all").disable()
    ,
    getText("*").remove()
    ,
    newController("DashedSentence", {s : row.Oracion}).center().print().wait().remove()
    ,
    n_question = 1+Math.floor(Math.random()*4)
    ,
    newText("q", row['Q'+n_question])
      .center()
      .print()
    ,
    newKey("pressOnArrow", "ArrowLeft", "ArrowRight").log().wait()
  )
  .log("n_question", n_question)
  .log("question", row['Q'+n_question])
)

Hi Philip,

I don’t get any error for this:

PreloadZip("https://yoojun.dreamhosters.com/eyetracking/pictures.zip")

newTrial(
    newImage("Picture1.png").print()
    ,
    newButton("Next").print().wait()
)

Did you happen to fix the issue in the meantime?

Jeremy

[Jeremy]

Hi Jana,

The behavior you see with the OralProduction (MediaRecorder) project is the default behavior: if the upload request fails, participants will see a link to download an archive with their recordings. If you want to force that to happen, you can use DownloadRecordingButton (there’s a code piece that illustrates its use on the documentation page)

Hi,

Add these two lines just after your SCRIPT tag:

const hideEm = ()=>{ 
if (document.getElementById("numlang")===null) return window.requestAnimationFrame(hideEm);

and these two just before function getVal(){:

};
hideEm();

This will make sure that the hiding commands will only be run after the elements were added to the page

Hello Ana-Maria,

Your reasoning is on the right track, but things work slightly differently: tests embedded in a success command won’t count as conjoined to the main test. For that, you have the and command. You can do this:

newTrial(
    newScale("comprehensibility_prac1", 8).print(),
    newScale("comprehensibility_prac2", 8).print(),
    newScale("comprehensibility_prac3", 8).print()
    ,
    newButton("validation", "Confirm")
        .center()
        .print()
        .wait( 
            getScale("comprehensibility_prac3" ).test.selected()
            .and( getScale("comprehensibility_prac2").test.selected() )
            .and( getScale("comprehensibility_prac1").test.selected() )
            .failure(
                newText("timedout","<b>Please use all the scales!</b>")
                    .css("font-size", "19px")
                    .css("font-family","times-new")
                    .color("red")
                    .center()
                    .print()     
            )
        )
)

Note that the error message will appear whenever any scale is unselected

If you want scale-specific messages, you could conjoin all three tests to a main test, so you can apply test-specific failures:

newTrial(
    newScale("comprehensibility_prac1", 8).print(),
    newScale("comprehensibility_prac2", 8).print(),
    newScale("comprehensibility_prac3", 8).print()
    ,
    defaultText
        .css("font-size", "19px")
        .css("font-family","times-new")
        .color("red")
        .center()
    ,
    newButton("validation", "Confirm")
        .center()
        .print()
        .wait( 
            newVar("dummy", 1).test.is(1)
                .and( getScale("comprehensibility_prac3" ).test.selected().failure( 
                    newText("timedout3","<b>Please use scale 3!</b>").print()
                ) )
                .and( getScale("comprehensibility_prac2" ).test.selected().failure( 
                    newText("timedout2","<b>Please use scale 2!</b>").print()
                ) )
                .and( getScale("comprehensibility_prac1" ).test.selected().failure( 
                    newText("timedout1","<b>Please use scale 1!</b>").print()
                ) )
        )
)
