removestimulusframe, insertstimulusframe - Response not correct

dschulz — Wed, 16 Nov 2022 20:25:04 GMT

Dear community, dear Dave,

I have a question. I'm trying to present a word and have every letter be its own stimulus. If one letter is pressed, I want to replace its image with a strike-through version of it. And the other way around: If a striked-through character is pressed, the non-striked-through version should be shown.
I got far enough to replace a non-striked version with a striked version. However, if I then press on the strike-letter, Inquisit still logs the response as the non-striked letter (e.g. h_upper_pure, not h_upper_strike). Therefore, I have no way to display the non-striked letter again, because Inquisit can't distinguish the stimuli.

I appended the code below.

Thank you in advance for your help

Dear Dave,

yes variables, were my backup plan. But thank you for the explanation, that makes sense!

For what it's worth, the whole setup might be a lot less complicated if you define just 5 on-screen objects with 2 items each ("pure" letter, "striked" letter) and then just switch back and forth between the two item states.

/ l5_state = 1
</values>

<text l1>
/ items = ("H", "<s>H</s>")
/ position = (40%, 50%)
/ select = values.l1_state
/ erase = false
</text>

<text l2>
/ items = ("e", "<s>e</s>")
/ position = (45%, 50%)
/ select = values.l2_state
/ erase = false
</text>

<text l3>
/ items = ("l", "<s>l</s>")
/ position = (50%, 50%)
/ select = values.l3_state
/ erase = false
</text>

<text l4>
/ items = ("l", "<s>l</s>")
/ position = (55%, 50%)
/ select = values.l4_state
/ erase = false
</text>

Hey Dave,

that looks like a very clean approach! I will adopt this, thank you!

A quick question :Are the semicolons after the brackets ({};) necessary? I know they are necessary after every expression (e.g. values.x = 2;), but I never use them after brackets and have not yet ran into trouble.

Thanks again for the idea.

Best,
Daniel

> Are the semicolons after the brackets ({};) necessary?

It depends. ";" is the statement separator, so if a given statement formally ends, it's generally best to close it out with a semicolon. Personally, I also find it improves code readability (along with proper indentation).

Alright great, thank you.

And your approach worked like a charm

Hey Dave,

that looks like a very clean approach! I will adopt this, thank you!

A quick question :Are the semicolons after the brackets ({};) necessary? I know they are necessary after every expression (e.g. values.x = 2;), but I never use them after brackets and have not yet ran into trouble.

Thanks again for the idea.

Best,
Daniel

> Are the semicolons after the brackets ({};) necessary?

It depends. ";" is the statement separator, so if a given statement formally ends, it's generally best to close it out with a semicolon. Personally, I also find it improves code readability (along with proper indentation).

Dear community, dear Dave,

I have a question. I'm trying to present a word and have every letter be its own stimulus. If one letter is pressed, I want to replace its image with a strike-through version of it. And the other way around: If a striked-through character is pressed, the non-striked-through version should be shown.
I got far enough to replace a non-striked version with a striked version. However, if I then press on the strike-letter, Inquisit still logs the response as the non-striked letter (e.g. h_upper_pure, not h_upper_strike). Therefore, I have no way to display the non-striked letter again, because Inquisit can't distinguish the stimuli.

I appended the code below.

Thank you in advance for your help

Dear Dave,

yes variables, were my backup plan. But thank you for the explanation, that makes sense!

For what it's worth, the whole setup might be a lot less complicated if you define just 5 on-screen objects with 2 items each ("pure" letter, "striked" letter) and then just switch back and forth between the two item states.

</text>

/ items = ("e", "<s>e</s>")
/ position = (45%, 50%)

Dear community, dear Dave,

I have a question. I'm trying to present a word and have every letter be its own stimulus. If one letter is pressed, I want to replace its image with a strike-through version of it. And the other way around: If a striked-through character is pressed, the non-striked-through version should be shown.
I got far enough to replace a non-striked version with a striked version. However, if I then press on the strike-letter, Inquisit still logs the response as the non-striked letter (e.g. h_upper_pure, not h_upper_strike). Therefore, I have no way to display the non-striked letter again, because Inquisit can't distinguish the stimuli.

I appended the code below.

Thank you in advance for your help
