Adding text to a Likert scale and creating an attention check

dinghu — Tue, 07 May 2024 18:51:38 GMT

Hello,
I am running an experiment in which participants will be making ratings on a 7 point Likert type scale after viewing stimuli. I currently have the Likert scale set up with only the buttons and corresponding ratings, but I wanted to also have the rating prompt presented with the scale each time. How do I add just some text above the Likert scale?

[code]<likert ratingtrial>
/ ontrialbegin = [
    likert.ratingtrial.resetstimulusframes();
    likert.ratingtrial.insertstimulustime(picture.mask, 250 + values.viewtime);
    likert.ratingtrial.insertstimulustime(clearscreen, 250 + values.viewtime + 50);
]
/ pretrialpause = 300
/ stimulustimes = [0=fix; 200=mask; 250=clearscreen; 250=site]
/ anchors=[1="very unaesthetic"; 2="unaesthetic"; 3="somewhat unaesthetic"; 4="neutral"; 5="somewhat aesthetic"; 6="aesthetic"; 7="very aesthetic"]
/ numpoints = 7
/ position=(50, 50)
/ posttrialpause = 100
/ buttonvalues = [1="1",2="2",3="3",4="4",5="5",6="6",7="7"]
/ mouse = true
</likert>[/code]
Additionally, I want to include a short attention check towards the end of my experiment. Could I just add another Likert type scale with a question and set one of the answers as the correct one?

You need a <text> element for the prompt and display that via /stimulustimes, just like any and all other stimuli.

And yes, you can do whatever you want or need for an attention check
[/quote]

Thank you so much! With the attention check, is there a way for me to insert one into part of a block, perhaps about 15 trials into a block? Or will I have to break the block up into two separate blocks, and have an attention check block in between?
[/quote]

You can insert it into a block however you deem fit. How to do that depends on how you've set the block up. That information is not available to me, so I can't give you any specific guidance.

I've pasted part of the code below. Each experiment is set up to run a practice block and then 3 blocks with different amounts of viewing time. I want to insert an attention check about 15 trials into the first of the actual experimental blocks without interfering with anything else. How would I be able to do that?
Thank you for your time!
[code]<expt>
/ onexptbegin = [
    values.filtergroup = 1;
    values.viewtimegroup = 1;
]
/ postinstructions = (end)
/ blocks = [1 = practice; 2 - 4 = test]
/ groups = (1 of 18)
</expt>

<block practice>
/ onblockbegin = [
    values.viewtime = 50; // 50 ms viewtime during practice
]
/ preinstructions = (intro1)
/ trials = [1-3 = ratingtrial]
</block>

<block test>
/ onblockbegin = [
    values.viewtime = list.viewtime.nextvalue;
]
/ trials = [1-50 = ratingtrial]
</block>
[/code]
[/quote]

Create a variable which you increase by one /ontrialbegin in every ratingtrial. Also create a variable indicating after how many test trials the attention check should occur.
[code]
<values>
...
/ ntrials = 0
/ attentioncheck_after = 0
...
</values>[/code]

At the start of the <expt>, pick a random number between 15 and, let's say 20, test trials after which the attention check should occur.

[code]<expt>
/ onexptbegin = [
    values.filtergroup = 1;
    values.viewtimegroup = 1;
    values.attentioncheck_after = round(rand(15, 20));
]
/ postinstructions = (end)
/ blocks = [1 = practice; 2 - 4 = test]
/ groups = (1 of 18)
</expt>[/code]

At the end of the practice block, set the trial count variable back to 0 (you only care about the number of test trials).

[code]<block practice>
...
/ onblockend = [values.ntrials = 0]
....
</block>[/code]

In your ratingtrial likert, increase the trial count variable by one and branch to the attentioncheck after the randomly determiined amount of test trials.

[code]<likert ratingtrial>
/ ontrialbegin = [values.ntrials += 1]
...
/ branch = [
    if (values.ntrials == values.attentioncheck_after) {
        return likert.attentioncheck;
    }
]
</likert>[/code]
[/quote]

Thank you so much for breaking it down like this. I just wanted to reply and share for posterity that I modified it to run on trial 15 each time, which made it unnecessary to include the attentioncheck_after value. I instead had it check if values.ntrail = 15, and simply branch from there. Thank you so much once again, you are a life saver!
