Counting the number of times someone presses the space bar

Hey,

Is there an option where inquisit can count the number of times someone presses the spacebar?

Hi Dave,

I am doing an online study and want to redirect people from Qualtrics to Inquisit and back to Qualtrics.
I followed the instructions I found online, but there seems to be an error.
The subjectid is coupled correctly. The problem is that when clicking the start button when Inquisit opens directly redirects you to Qualtrics.
The finish page immediately opens, without the Inquisit game actually playing.
I start to think there is something wrong in my script, but I am don't know what the problem could be.

This is the link to the Qualtrics survey: https://psychru.eu.qualtrics.com/jfe/preview/SV_bCq7EvFp4xmtv25?Q_SurveyVersionID=current&Q_CHL=preview
I also attached the data files of Inquisit. The start file is the batch file "garbage_game"

Thank you in advance for your help!

Your batch script tries to assign conditions based on subject number:

<batch>
/subjects = (1 of 2)
/file = "surroundings.iqx"
/ groupassignment = subjectnumber
</batch>

<batch>
/subjects = (2 of 2)
/file = "environment.iqx"
/ groupassignment = subjectnumber
</batch>

Condition assignment is a mathematical operation, i.e. for this to work, subject IDs must be strictly numerical. Qualtrics IDs are not numerical, they're strings of letters and numbers, i.e. alphanumerical. As a consequence, no condition applies, and the batch immediately ends without any of the scripts having been run.

Change the /groupassignment method to groupnumber and select an appropriate group ID generation method in your web experiment's settings.

Thank you, that solves the problem!

Hi Dave,

The script is almost done!
It counts how many times a person presses spacebar after 'picking up garbage'. A picture of garbage appears, and when you press spacebar the picture dissappears and a new one will appear in a random time interval. So sometimes the new picture appears immediately, sometimes it takes a couple of seconds. This is done witch counter.

We have included a text element in the corner of the screen which shows the number of times spacebar is pressed.

The problem is, the counter delays the moment the picture is presented, but it also delays the text element which shows the number of times spacebar is pressed. This is because they are both included in the trials.

When playing the game it is distracting that the text with the score also disappears and reappears. Would you know a solution for this, while still counting the number of times someone presses spacebar?

Thank you,

Sanne

I cannot comment on that because you did not share how you actually did this, i.e. the actual code. There is no reason per se why a trial cannot present one stimulus at time X and another stimulus at time Y. One need not delay the other.

Set the <text> element's /erase attribute to false.

Thank you! The erase attribute actually solved the problem :)

Thank you very much! I tried some tutorials but still I'm a bit confused..

I actually have two conditions.

I made this after your help:

<block experiment1>
/trials = [1-4=sequence(story1, pictures1)]
/ preinstructions = (welcome, instructions1a)
</block>

<block experiment2>
/trials = [1-4=sequence(story2, pictures2)]
/ preinstructions = (welcome, instructions2a)
</block>

I'm not sure how I can randomly assign one of the two experiments to the participants.
I could use

<expt>
/ subjects (1 of 2)

but I don't want to run both blocks.
I read some other threats about the subject but I'm a bit overwhelmed..

You need to set up two <expt> elements in your script. One that runs only the story 1 block, another that only runs the story 2 block. Then assign participants to one of those two <expt>s by either group ID, subject ID or randomly. Since you're planning to run this one the web, I recommed you assign based on group ID and select random generation of group IDs in the web experiment's settings once you upload it.

<expt>
/ subjects = (1 of 2)
/ groupassignment = groupnumber
/ blocks = [1 = experiment1]
</expt>

<expt>
/ subjects = (2 of 2)
/ groupassignment = groupnumber
/ blocks = [1 = experiment2]
</expt>

I have some more questions and it would be great if you could help me.

I want to have text and images which participants will only view. They don't have to do anything but going to the next page.
The sequence of presentation has to be: image1, text1, image2, text2, image3, text3, image4, text4.
I cannot use /select = sequence, but I have no idea how I can switch between the two.

Also, I don't know how to upload an image. I used this:

<item pictures1>
/1 =
/2 =
/3 =
/4 =
</item>

<image pictures1>
/ caption=""
/ items=("pictures1")
</image>

But I don't know how to actually refer to an image. I want to make an online game/survey. Would it be possible to share the experiment online?
If so, how would inquisit be able to 'find' the picture when the survey is run on another computer?

This should be pretty straightforward. Set up two <trial> elements, one to display the "text" page, one to display the "image" page. Run them in sequence.

<block example>
/ trials = [1-4 = sequence(picturetrial, texttrial)]
</block>

<trial picturetrial>
/ stimulusframes = [1=mypicture]
/ validresponse = (57)
</trial>

<trial texttrial>
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>

<picture mypicture>
/ items = pictureitems
/ select = sequence
</picture>

<item pictureitems>
/ 1 = "image1.jpg"
/ 2 = "image2.jpg"
/ 3 = "image3.jpg"
/ 4 = "image4.jpg"
</item>

<text mytext>
/ items = textitems
/ select = sequence
</text>

<item textitems>
/ 1 = "text 1"
/ 2 = "text 2"
/ 3 = "text 3"
/ 4 = "text 4"
</item>

As for any image files, enter the file names into the <item> element, and upload the files along with the script when you deploy the experiment online.

You'll find basics like this covered in the tutorials, give those a go if you haven't already. https://www.millisecond.com/support/docs/v4/html/tutorials/tutorials.htm
