Millisecond Forums

Hi, I am posting my entire inquist code below for reference. I have coded this such that if the airplane stimuli is displayed on the screen, a white rectangle blocks out another stimuli that is displayed on scree. This works for all trials except in either trial test_2a, or test2, regardless of the stimuli presented, the right side of the screen is always blocked out. Can you help me debug this? Thank you.

Please don't paste entire scripts into a post's body. This is error prone and difficult to work with. Further, if your code requires external files to run (images, etc.), you need to provide those files along with it. Helping you debug your problem is obviously not possible otherwise.

Please put everything in a ZIP archive and then attach the archive to your post via +Insert -> Add File...
If the archive is too large to attach here, upload it somewhere else (e.g. your DropBox or similar) and provide the download link.

Hi, I am posting my entire inquist code below for reference. I have coded this such that if the airplane stimuli is displayed on the screen, a white rectangle blocks out another stimuli that is displayed on scree. This works for all trials except in either trial test_2a, or test2, regardless of the stimuli presented, the right side of the screen is always blocked out. Can you help me debug this? Thank you.

Please don't paste entire scripts into a post's body. This is error prone and difficult to work with. Further, if your code requires external files to run (images, etc.), you need to provide those files along with it. Helping you debug your problem is obviously not possible otherwise.

Please put everything in a ZIP archive and then attach the archive to your post via +Insert -> Add File...
If the archive is too large to attach here, upload it somewhere else (e.g. your DropBox or similar) and provide the download link.

Hi Dave,
My apologies, I have attached the file here 
Thank you

Hi, I am posting my entire inquist code below for reference. I have coded this such that if the airplane stimuli is displayed on the screen, a white rectangle blocks out another stimuli that is displayed on scree. This works for all trials except in either trial test_2a, or test2, regardless of the stimuli presented, the right side of the screen is always blocked out. Can you help me debug this? Thank you.

Please don't paste entire scripts into a post's body. This is error prone and difficult to work with. Further, if your code requires external files to run (images, etc.), you need to provide those files along with it. Helping you debug your problem is obviously not possible otherwise.

Please put everything in a ZIP archive and then attach the archive to your post via +Insert -> Add File...
If the archive is too large to attach here, upload it somewhere else (e.g. your DropBox or similar) and provide the download link.

Hi Dave,
My apologies, I have attached the file here 
Thank you

I'm not sure I understand the issue. Here's what I'm seeing when running the cpc_girls.iqx script from your archive, which seems to match what you pasted in your original post. I gave the masking rectangle a blue color, so it's very obvious whether it's displayed or not.

Here is a run that had airplanes in test2a



and here's one that had airplanes in test2:



The problem isn't the rectangle, that's working fine. The problem is with the girl pics.

Both blocks test2 and test2a display girl d, j, and h.

<block test2_girls>
/trials = [1 = test2_intro; 2 = test1_speech; 3 = judgment]
/ bgstim = (
girl_d,
girl_j,
girl_h,
activity_group)
</block>

Girl D is on the left at 25%
<picture girl_d>
/items = girls
/select = 7
/size = (30%,30%)
/hposition = 25%
/vposition = 50%
/ erase = false
</picture>

Girl J is ALSO at 25%, so you never see Girl D
<picture girl_j>
/items = girls
/select = 13
/size = (30%,30%)
/hposition = 25%
/vposition = 50%
/ erase = false
</picture>

Girl H is in the center
<picture girl_h>
/items = girls
/select = 11
/size = (30%,30%)
/hposition = 50%
/vposition = 50%
/ erase = false
</picture>

NO girl stimulus is on the right at 75% ever. It's not blocked out, there just isn't one.

If I had to guess, I'd say that Girl D is all wrong for these blocks, but you'll know that better than I.

Hi, I am posting my entire inquist code below for reference. I have coded this such that if the airplane stimuli is displayed on the screen, a white rectangle blocks out another stimuli that is displayed on scree. This works for all trials except in either trial test_2a, or test2, regardless of the stimuli presented, the right side of the screen is always blocked out. Can you help me debug this? Thank you.

Hi Dave,
My apologies, I have attached the file here 
Thank you

I'm not sure I understand the issue. Here's what I'm seeing when running the cpc_girls.iqx script from your archive, which seems to match what you pasted in your original post. I gave the masking rectangle a blue color, so it's very obvious whether it's displayed or not.

Here is a run that had airplanes in test2a



and here's one that had airplanes in test2:



The problem isn't the rectangle, that's working fine. The problem is that with the girl pics.

Both blocks test2 and test2a display girl d, j, and h.

<block test2_girls>
/trials = [1 = test2_intro; 2 = test1_speech; 3 = judgment]
/ bgstim = (
girl_d,
girl_j,
girl_h,
activity_group)
</block>

Girl D is on the left at 25%
<picture girl_d>
/items = girls
/select = 7
/size = (30%,30%)
/hposition = 25%
/vposition = 50%
/ erase = false
</picture>

Girl J is ALSO at 25%, so you never see Girl D
<picture girl_j>
/items = girls
/select = 13
/size = (30%,30%)
/hposition = 25%
/vposition = 50%
/ erase = false
</picture>

Girl H is in the center
<picture girl_h>
/items = girls
/select = 11
/size = (30%,30%)
/hposition = 50%
/vposition = 50%
/ erase = false
</picture>

NO girl stimulus is on the right at 75% ever. It's not blocked out, there just isn't one.

If I had to guess, I'd say that Girl D is all wrong for these blocks, but you'll know that better than I.

Thank you!
