varying word presentation depending on length

[yanaib]

Hi,

I can’t quite figure out how to add varying word presentation time to dashedsentence (in speeded acceptability mode). I would like to display every word up to 12 characters long for 250ms, and then add 20 extra ms for every character over 12, i.e. a word of 14 characters will be displayed for 290ms.

I’ve added the following to the wordPauseTimeout() function (line 152, I think).:

if (t.words[t.currentWord].length > 12) {
var extraTime = (t.words[t.currentWord].length – 12) * 20;
t.wordTime = t.wordTime + extraTime;
}

Judging from console.log, it looks like it’s at least executed at the right time, but this updated controller breaks the word-by-word presentation: the whole sentence is presented, and then a few first words are removed left to right one by one. I’m not sure exactly what I’m getting wrong, and I’m especially confused as to why this disrupts word-by-word presentation: I wrote an if statememnt specifically to isolate it from the rest of the code so that it at least doesn’t break it if it fails to work.

I would appreciate any help!

Many thanks

Hi Yana,

I think you’re doing the right thing inserting your code in the wordPauseTimeout function, but when I open the js file I see that line 152 is part of the wordTimeout function, so I just want to make sure you’re editing the right function.

However I’m afraid that directly modifying t.wordTime will cause problems after encountering the first over-12-character word, because the subsequent words will inherit the extra duration. Here is how I rewrote the whole if statement, and it seems to be working smoothly:

if (this.mode == "speeded acceptability") {
    var t = this;
    function wordTimeout() {
        t.blankWord(t.currentWord);
        ++(t.currentWord);
        if (t.currentWord >= t.stoppingPoint)
            t.finishedCallback([[["Sentence (or sentence MD5)", t.sentenceDesc]]]);
        else
            t.utils.setTimeout(wordPauseTimeout, t.wordPauseTime);
    }
    function wordPauseTimeout() {
        t.showWord(t.currentWord);
        t.utils.clearTimeout(wordPauseTimeout);
        let duration = t.wordTime;
        if (t.words[t.currentWord].length > 12) {
            var extraTime = (t.words[t.currentWord].length - 12) * 200;
            duration += extraTime;
        }
        t.utils.setTimeout(wordTimeout, duration);
    }
    wordPauseTimeout();
}

I used 200 so I could clearly tell when the extra time was added to the normal display time. For reference, here are the parameters I used to test the DashedSentence:

{
  s: "Extralongitudinal is not a word that makes much anticonstitutional sense",
  wordTime: 250,
  mode: "speeded acceptability"
}
