natash - 5/7/2020

Hi together, 

I'm programming a "game" in Inquisit for an experiment. For that the person is being shown 12 pictures and he/she has to select three of them that belong together. 

Now I came across the problem that I don't know how to program that the person can select three pictures and not only one, and it would be nice if it would be shown which pictures the person already has selected and that he/she can undo the her/his choice.

I attached my script, maybe it is only possible with checkboxes but it would be a lot nicer if it would work without them as well and only with the pictures. For simplicity I'm only working with one picture right now before I've got the script running correctly.

Thank you!

There are a number of scripts in the library which do something similar, so you may want to work through those.

Thanks a lot! I'm still a bit confused, where is the possiblity to specify my pictures? This is very advanced for me, so excuse me for the questions

Instead of <text> elements, use <picture> elements. Works the same way.

That helped a lot! Now it works perfectly, the only thing is that I need it to pursue after the Person has selected three items and clicked done, then it should go on to the next items. It would be amazing if you could help me there as well

Hi together, 

I'm programming a "game" in Inquisit for an experiment. For that the person is being shown 12 pictures and he/she has to select three of them that belong together. 

Now I came across the problem that I don't know how to program that the person can select three pictures and not only one, and it would be nice if it would be shown which pictures the person already has selected and that he/she can undo the her/his choice.

I attached my script, maybe it is only possible with checkboxes but it would be a lot nicer if it would work without them as well and only with the pictures. For simplicity I'm only working with one picture right now before I've got the script running correctly.

Thank you!

There are a number of scripts in the library which do something similar, so you may want to work through those.

You need to spell out clearly what exactly you want to do and what exactly you don't know how to do. I.e. which parts of the code I gave you do you not understand? Then I can explain those to you and you can take it from there.

I actually think that I understand all of it. My problem is that right now it shows 4 Items and if I select three of them and click on "done" then it quits the session. What I want is that after I selected three items that it goes on to show me 4 new items from which I again have to choose three and so o

Thanks a lot! I'm still a bit confused, where is the possiblity to specify my pictures? This is very advanced for me, so excuse me for the questions

Instead of <text> elements, use <picture> elements. Works the same way.

That helped a lot! Now it works perfectly, the only thing is that I need it to pursue after the Person has selected three items and clicked done, then it should go on to the next items. It would be amazing if you could help me there as well

You need to spell out clearly what exactly you want to do and what exactly you don't know how to do. I.e. which parts of the code I gave you do you not understand? Then I can explain those to you and you can take it from there.

I actually think that I understand all of it. My problem is that right now it shows 4 Items and if I select three of them and click on "done" then it quits the session. What I want is that after I selected three items that it goes on to show me 4 new items from which I again have to choose three and so o

And then what? What's the relationship between the four items in every, let's call it set of four items? Why only four? For the record, I chose four for the sake of illustration, you can extend it to 3 out of 8, 10, 12 -- whatever you need or want. The vague information I have from you is not something I can reasonably work with, I'm afraid.

Hi together, 

I'm programming a "game" in Inquisit for an experiment. For that the person is being shown 12 pictures and he/she has to select three of them that belong together. 

Now I came across the problem that I don't know how to program that the person can select three pictures and not only one, and it would be nice if it would be shown which pictures the person already has selected and that he/she can undo the her/his choice.

I attached my script, maybe it is only possible with checkboxes but it would be a lot nicer if it would work without them as well and only with the pictures. For simplicity I'm only working with one picture right now before I've got the script running correctly.

Thank you!

Okay, so here's a fairly straightforward extension of the code. Suppose you have five sets of four items each. Each set consists of three targets and one distractor item. The game thus lasts five rounds, and will give feedback about how many of the targets were identified after each round. The sets 1 to 5 are presented in random order.

<defaults>

<values>
/ target_1_x = 0%

/ target_3_x = 0%
/ target_3_y = 0%
/ distractor_1_x = 0%
/ distractor_1_y = 0%
/ target_1_selected = 0
/ target_2_selected = 0
/ target_3_selected = 0
/ distractor_1_selected = 0
/ set = 1
</values>

<expressions>
/ n_selected = (values.target_1_selected + values.target_2_selected + values.target_3_selected + values.distractor_1_selected)
</expressions>

// five sets of four items each (three targets, one distractor)

Thanks a lot! I'm still a bit confused, where is the possiblity to specify my pictures? This is very advanced for me, so excuse me for the questions

Instead of <text> elements, use <picture> elements. Works the same way.

That helped a lot! Now it works perfectly, the only thing is that I need it to pursue after the Person has selected three items and clicked done, then it should go on to the next items. It would be amazing if you could help me there as well

You need to spell out clearly what exactly you want to do and what exactly you don't know how to do. I.e. which parts of the code I gave you do you not understand? Then I can explain those to you and you can take it from there.

I actually think that I understand all of it. My problem is that right now it shows 4 Items and if I select three of them and click on "done" then it quits the session. What I want is that after I selected three items that it goes on to show me 4 new items from which I again have to choose three and so o

And then what? What's the relationship between the four items in every, let's call it set of four items? Why only four? For the record, I chose four for the sake of illustration, you can extend it to 3 out of 8, 10, 12 -- whatever you need or want. The vague information I have from you is not something I can reasonably work with, I'm afraid.

Okay, so here's a fairly straightforward extension of the code. Suppose you have five sets of four items each. Each set consists of three targets and one distractor item. The game thus lasts five rounds, and will give feedback about how many of the targets were identified after each round. The sets 1 to 5 are presented in random order.

<defaults>

<values>
/ target_1_x = 0%
/ target_1_y = 0%
/ target_2_x = 0%
/ target_2_y = 0%
/ target_3_x = 0%
/ target_3_y = 0%
/ distractor_1_x = 0%
/ distractor_1_y = 0%
/ target_1_selected = 0
/ target_2_selected = 0
/ target_3_selected = 0
/ distractor_1_selected = 0
/ set = 1
</values>

<expressions>
/ n_selected = (values.target_1_selected + values.target_2_selected + values.target_3_selected + values.distractor_1_selected)
</expressions>

wow thanks a lot! I will do it with 12 items, but that helps so much!!
