Show an image if a condition is satsfied

sbashyam — Mon, 07 Aug 2023 12:05:22 GMT

Hi,
I am in the process of creating a study on inquist, but need help with conditionally displaying an image. I want to code the study in such a way that if a certain picture is displayed (there are two out of eight such pictures that randomly display on two trials), then another picture also gets displayed along with it.

Thank you!

Hi Dave,

Thank you for all your help previously! The code works, but in some cases (see screenshot below) for the cupcake stimuli, we have three boys appearing on screen. However, this error is not consistent - it turns up randomly. When I test run the code, it goes okay but when we try it on a participant, sometimes it fails to cover the third boy/girl.
We find this error in both cpc_boys.iqx file and cpc_girls.iqx file.

Figure out in which blocks this happens by looking at the data, then work backwards from there to locate the mistakes in your scripts.

The type of mistakes to look out for: For example, in test5a_intro, you're not actually inserting the white rectangle into the test5a_intro trial's stimulus presentation sequence.

You're inserting it into an entirely different, irrelevant trial's stimulus presentation sequence, test5_intro. So, nothing will be covered up in test5a_intro.

<trial test5a_intro>
/ ontrialbegin = [
trial.test5a_intro.resetstimulusframes(); // resets the trial's stimulus presentation sequence to its initial state
picture.lightblue_circle_right.hposition = 75%; // sets circle of left boy to its normal position
picture.lightblue_black_circle_left.hposition = 25%; // sets circle of right boy to its normal position
if (picture.activity_group.currentitem == "cupcakes.png" || picture.activity_group.currentitem == "airplanes.png") { // if current activity is either cupcakes or airplanes
values.x = replace(75%);
trial.test5_intro.insertstimulusframe(shape.whiterect, 1); // cover up the randomly picked boy with white rectangle
};
]
/stimulusframes = [1=continue]
/ validresponse = (continue)
</trial>

Hi Dave, thank you for all your help previously. I was trying to remove the randomization and run this code to only cover the left side. But when I run this and click on continue, all the screen goes blank and i can only see the speech bubble. Previously I was seeing the boys and the speech bubble. Could you please correct me with where I might be going wrong

Please take another close look at the code I gave you. Everything in there is important, including the /erase = false settings for the various stimuli.

My apologies if I am being unclear, but this is my first time seeking help online on the forum so please bear with me. I meant to say that I want to ensure that the two boys that remain (after the white rectangle covers the third one), each have two circles of different colours (just as you mentioned, one green and one blue). I appreciate your help and prompt responses but I am also learning on how to use this software.

Thank you! Could you help me out by also making sure that when the cupcakes or airplane stimuli appear, both boys that are presented on the screen have two different colour over their head? Right now it shows one with one coloured circle and the other with two different coulour circles
[/quote]

What? I'm sorry, but you're not very clear regarding what you want. What is "[r]ight now it shows one with one coloured circle and the other with two different coulour circles" supposed to mean? That's not even correct; it depends on whether the left boy or the right boy is not shown. And what is "two different colour over their head" supposed to mean? In your script, as it exists, the colors aren't different. Left boy has a single blue circle, middle & right boy have a green & blue circle each.

Randomly determined
[/quote]

Attached a runnable example of how you need to set up the blocks, trials, and stimulus elements to make this work. This just runs the test1_boys block eight times, so you can see what happens when either cupcakes or airplanes are the selected activity. You'll have to change the other blocks etc. in the script accordingly.

Thanks, I have the files now.

Help me understand:

- The "white rectangle" is supposed to be displayed when and where exactly?
- The screen color throughout the task is white, so how is one supposed to notice the presence of the "white rectangle"?
- You have files called rec1.png to rec8.png included in the folder you shared, but these aren't used anywhere in the script. What are they for?
- What, if anything, are participants supposed to do with the "white rectangle"?
[/quote]

To add: What is the purpose of the "activity_alone" picture element, as opposed to the "activity_group" picture?

There are no comments at all throughout your code, nor are there instructions, so it's impossible to determine what it is intended to do.
[/quote]
Whenever the cupckaes or airplane stimuli is displayed, I need the white rectangle to cover the boy on the right or the left.
The purpose is to ensure that there are only two boys on the screen as opposed to white
Those files were meant to be used in another version of the experiment, but we don't need them anymore
Activity alone vs activity group is from a previous version of the experiment, not of use now.

I basically need to show just two boys for the stimuli "cupcakes" and "airplanes". I thought covering the third boy who shows up by default was the only way.

> Whenever the cupckaes or airplane stimuli is displayed, I need the white rectangle to cover the boy on the right or the left.

Like what? Always the one on the left or always the one on the right or is this supposed to be randomly determined somehow?
