Hey there!

Hope all is well. I just need a tad bit of help for the following situation:

Say that you have 40 comprehension questions, some require a YES response ("E") or a NO response ("I") (one or the other, but not both). I have created lists for the respective comprehension question for each type of response (I won't paste all the comprehension question items here, but this is done in script of course):

<list Eresponse>
/ items = (1,2,4,5,7,11,13,16,18,26,29,34,40)
/ selectionmode = text.comprehension.currentindex
</list>

<list Iresponse>
/ items = (3,6,12,15,21,23,28,30,33,39)
/ selectionmode = text.comprehension.currentindex
</list>

Thus, when it comes to the trial, I am telling Inquisit to register what is 'correct'. For example, if they are presented with (question) item 1 from above, then this requires E (yes) to be pressed, as it belongs to the Eresponse list. If they press I, then this is incorrect. This is what I have so far for the trial code:

<trial comprehension>
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = (trial.comprehension.response == list.Eresponse.nextvalue....

But this means iscorrectresponse is only dealing with the Eresponses?, I am unsure as to code up to ensure that a correct response depends on which type of comprehension question it belongs to - list E (for yes) or list I (for no). This is where I am stuck. I considered using <values> but could not fathom it.

Dave has already allowed me to make huge progress with this experiment I am running (with a full Inquisit license) and relates to my recent post titled 'branching' (about adapting LDT to incorporate scenarios, comprehension questions etc). Well It has all come together thanks to that single piece of advice thus far, so thank you so much. It is just this part I have run into bother with. I reckon I should be okay after this point.

The script is simple, and it works and runs the task, and so thought I'd attach here just in case (I know your amazing expertise allows you to understand what's going on straight away!)

Thank you kindly
Yours Sincerely
Anthony

You ought to have one <list> storing the responses for all questions; as its /items the list ought to contain the keyboard scancode of the key that is the correct one for the given question.

"E" = scancode 18
"I" = scancode 23
<list correctkeys>
/ items = (18, 18, 23, 18, 18, 23, 18, 23, 23, 23, 18, 23, 18, 23, 23, 18, 23, 18, 23, 23, 23, 23, 23, 23, 23, 18, 23, 23, 18, 23, 23, 23, 23, 18, 23, 23, 23, 23, 23, 18)
/ selectionmode = text.comprehension.currentindex
</list>

with

<trial comprehension>
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = [trial.comprehension.response == list.correctkeys.nextvalue]

Ohhhhhhh, I was plugging in the actual question items, and not the scan code keys for each item, I'm such a nub lol, this genuinely has sparked a Eureka moment, I get it now lol. Thank you very much once again, this makes a huge difference!

Just to add, thank you for coding these respective keys here. I should like to mention that the following comprehension items (8,9,10,14,17,19,20,22,24,25,27,31,32,35,36,37,38) should be skipped (based on the nature of the experiment, since some pre-scenarios do not have comprehension questions attached to them at all, whilst others do (e.g. yes/no ones above)

Am I right in thinking I would add a /skip and somehow tell inquisit to filter these ones out?

Hi Dave. I Do not mean to be a bother, and I have thus far spent a day and a half working on this last issue before asking for help. Overall, my script/experiment works perfectly, kindly owed to your bits of advice above, thank you. I have only now to implement the remaining materials.
There is one last outstanding mystery, perhaps even an unsolvable bug dare I say? I have tried so many solutions honestly, and none have solved it, hence why I ask. As a reminder:

Scenario (press space once read) -- Single-target word (is it real or nonword?) --  (sometimes) a comprehension question (yes/no response).

For the majority of comprehension questions, the correct key mappings (via list as you advised) indeed works! For example, when I run the experiment, then check my raw data/output, under ‘correct’ column, the binary number (e.g. 0 or 1) corresponds to what was authentically correct, respectively. Either ‘E’ for yes or ‘I’ for no. However, those portion of questions specifically requiring a no (I) response, for some reason the ‘correct’ column inverts what the correct answer ought to be, for the following below comprehension question items:

ITEM 30 (answer = I)
ITEM 3 (answer = I)
ITEM 39 (answer = I)
ITEM 23 (answer = I)
ITEM 6 (answer = I)
ITEM 12 (answer = I)
ITEM 5 (answer = I)
ITEM 15 (answer = I)
ITEM 33 (answer = I)
ITEM 21 (answer = I)
ITEM 28 (answer = I)
ITEM 3 (answer = I)

e.g. for item 30, the question is ‘did you take a Chinese course?’. The answer to this is I/no. Yet in the binary (correct column), it produces a 0 if you press I, and a 1 if you press E! (hence invert). Bizarre no? And it is systematic for these ones above (I have doubly checked and must know them by heart by now lol). The yes/E questions work fine (e.g. binary 0, 1 responds equally correctly to an incorrect/correct response, respectively).
I tried changing key scans, re-typing items, swapping the correct keys for those select items, and much more. Nothing has done the trick at all. I paste the script here, and the file in case you wish to run so u can see the raw data. I’m so baffled, literally. The only thing I can now think of is something to do with lists, or making more lists or values but maybe I am wrong.

Thank you so much as always, I very much appreciate your help. I made all this script myself lol, and genuinely understand it, just so baffled by why correct output is systematically doing this for i/no responses.

Hey there!

Hope all is well. I just need a tad bit of help for the following situation:

Say that you have 40 comprehension questions, some require a YES response ("E") or a NO response ("I") (one or the other, but not both). I have created lists for the respective comprehension question for each type of response (I won't paste all the comprehension question items here, but this is done in script of course):

<list Eresponse>
/ items = (1,2,4,5,7,11,13,16,18,26,29,34,40)
/ selectionmode = text.comprehension.currentindex
</list>

<list Iresponse>
/ items = (3,6,12,15,21,23,28,30,33,39)
/ selectionmode = text.comprehension.currentindex
</list>

Thus, when it comes to the trial, I am telling Inquisit to register what is 'correct'. For example, if they are presented with (question) item 1 from above, then this requires E (yes) to be pressed, as it belongs to the Eresponse list. If they press I, then this is incorrect. This is what I have so far for the trial code:

<trial comprehension>
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = (trial.comprehension.response == list.Eresponse.nextvalue....

But this means iscorrectresponse is only dealing with the Eresponses?, I am unsure as to code up to ensure that a correct response depends on which type of comprehension question it belongs to - list E (for yes) or list I (for no). This is where I am stuck. I considered using <values> but could not fathom it.

Dave has already allowed me to make huge progress with this experiment I am running (with a full Inquisit license) and relates to my recent post titled 'branching' (about adapting LDT to incorporate scenarios, comprehension questions etc). Well It has all come together thanks to that single piece of advice thus far, so thank you so much. It is just this part I have run into bother with. I reckon I should be okay after this point.

The script is simple, and it works and runs the task, and so thought I'd attach here just in case (I know your amazing expertise allows you to understand what's going on straight away!)

Thank you kindly
Yours Sincerely
Anthony


You ought to have one <list> storing the responses for all questions; as its /items the list ought to contain the keyboard scancode of the key that is the correct one for the given question.

"E" = scancode 18
"I" = scancode 23
<list correctkeys>
/ items = (18, 18, 23, 18, 18, 23, 18, 23, 23, 23, 18, 23, 18, 23, 23, 18, 23, 18, 23, 23, 23, 23, 23, 23, 23, 18, 23, 23, 18, 23, 23, 23, 23, 18, 23, 23, 23, 23, 23, 18)
/ selectionmode = text.comprehension.currentindex
</list>

with

<trial comprehension>
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = [trial.comprehension.response == list.correctkeys.nextvalue]
...
</trial>

Just to add, thank you for coding these respective keys here. I should like to mention that the following comprehension items (8,9,10,14,17,19,20,22,24,25,27,31,32,35,36,37,38) should be skipped (based on the nature of the experiment, since some pre-scenarios do not have comprehension questions attached to them at all, whilst others do (e.g. yes/no ones above)

Am I right in thinking I would add a /skip and somehow tell inquisit to filter these ones out?

Yes. Something like

<trial comprehension>
/ skip = [
    item.comprehension.item(text.scenario.currentindex) == "+";
]
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = [trial.comprehension.response == list.correctkeys.nextvalue]
</trial>


Hi Dave. I Do not mean to be a bother, and I have thus far spent a day and a half working on this last issue before asking for help. Overall, my script/experiment works perfectly, kindly owed to your bits of advice above, thank you. I have only now to implement the remaining materials.
There is one last outstanding mystery, perhaps even an unsolvable bug dare I say? I have tried so many solutions honestly, and none have solved it, hence why I ask. As a reminder:

Scenario (press space once read) -- Single-target word (is it real or nonword?) --  (sometimes) a comprehension question (yes/no response).

For the majority of comprehension questions, the correct key mappings (via list as you advised) indeed works! For example, when I run the experiment, then check my raw data/output, under ‘correct’ column, the binary number (e.g. 0 or 1) corresponds to what was authentically correct, respectively. Either ‘E’ for yes or ‘I’ for no. However, those portion of questions specifically requiring a no (I) response, for some reason the ‘correct’ column inverts what the correct answer ought to be, for the following below comprehension question items:

ITEM 30 (answer = I)
ITEM 3 (answer = I)
ITEM 39 (answer = I)
ITEM 23 (answer = I)
ITEM 6 (answer = I)
ITEM 12 (answer = I)
ITEM 5 (answer = I)
ITEM 15 (answer = I)
ITEM 33 (answer = I)
ITEM 21 (answer = I)
ITEM 28 (answer = I)
ITEM 3 (answer = I)

e.g. for item 30, the question is ‘did you take a Chinese course?’. The answer to this is I/no. Yet in the binary (correct column), it produces a 0 if you press I, and a 1 if you press E! (hence invert). Bizarre no? And it is systematic for these ones above (I have doubly checked and must know them by heart by now lol). The yes/E questions work fine (e.g. binary 0, 1 responds equally correctly to an incorrect/correct response, respectively).
I tried changing key scans, re-typing items, swapping the correct keys for those select items, and much more. Nothing has done the trick at all. I paste the script here, and the file in case you wish to run so u can see the raw data. I’m so baffled, literally. The only thing I can now think of is something to do with lists, or making more lists or values but maybe I am wrong.

Thank you so much as always, I very much appreciate your help. I made all this script myself lol, and genuinely understand it, just so baffled by why correct output is systematically doing this for i/no responses.

Hey there!

Hope all is well. I just need a tad bit of help for the following situation:

Say that you have 40 comprehension questions, some require a YES response ("E") or a NO response ("I") (one or the other, but not both). I have created lists for the respective comprehension question for each type of response (I won't paste all the comprehension question items here, but this is done in script of course):

<list Eresponse>
/ items = (1,2,4,5,7,11,13,16,18,26,29,34,40)
/ selectionmode = text.comprehension.currentindex
</list>

<list Iresponse>
/ items = (3,6,12,15,21,23,28,30,33,39)
/ selectionmode = text.comprehension.currentindex
</list>

Thus, when it comes to the trial, I am telling Inquisit to register what is 'correct'. For example, if they are presented with (question) item 1 from above, then this requires E (yes) to be pressed, as it belongs to the Eresponse list. If they press I, then this is incorrect. This is what I have so far for the trial code:

<trial comprehension>
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = (trial.comprehension.response == list.Eresponse.nextvalue....

But this means iscorrectresponse is only dealing with the Eresponses?, I am unsure as to code up to ensure that a correct response depends on which type of comprehension question it belongs to - list E (for yes) or list I (for no). This is where I am stuck. I considered using <values> but could not fathom it.

Dave has already allowed me to make huge progress with this experiment I am running (with a full Inquisit license) and relates to my recent post titled 'branching' (about adapting LDT to incorporate scenarios, comprehension questions etc). Well It has all come together thanks to that single piece of advice thus far, so thank you so much. It is just this part I have run into bother with. I reckon I should be okay after this point.

The script is simple, and it works and runs the task, and so thought I'd attach here just in case (I know your amazing expertise allows you to understand what's going on straight away!)

Thank you kindly
Yours Sincerely
Anthony


You ought to have one <list> storing the responses for all questions; as its /items the list ought to contain the keyboard scancode of the key that is the correct one for the given question.

"E" = scancode 18
"I" = scancode 23
<list correctkeys>
/ items = (18, 18, 23, 18, 18, 23, 18, 23, 23, 23, 18, 23, 18, 23, 23, 18, 23, 18, 23, 23, 23, 23, 23, 23, 23, 18, 23, 23, 18, 23, 23, 23, 23, 18, 23, 23, 23, 23, 23, 18)
/ selectionmode = text.comprehension.currentindex
</list>

with

<trial comprehension>
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = [trial.comprehension.response == list.correctkeys.nextvalue]
...
</trial>

Just to add, thank you for coding these respective keys here. I should like to mention that the following comprehension items (8,9,10,14,17,19,20,22,24,25,27,31,32,35,36,37,38) should be skipped (based on the nature of the experiment, since some pre-scenarios do not have comprehension questions attached to them at all, whilst others do (e.g. yes/no ones above)

Am I right in thinking I would add a /skip and somehow tell inquisit to filter these ones out?

Yes. Something like

<trial comprehension>
/ skip = [
    item.comprehension.item(text.scenario.currentindex) == "+";
]
/ stimulusframes = [1=text.comprehension]
/ validresponse = ("E", "I")
/ iscorrectresponse = [trial.comprehension.response == list.correctkeys.nextvalue]
</trial>


Hi Dave. I Do not mean to be a bother, and I have thus far spent a day and a half working on this last issue before asking for help. Overall, my script/experiment works perfectly, kindly owed to your bits of advice above, thank you. I have only now to implement the remaining materials.
There is one last outstanding mystery, perhaps even an unsolvable bug dare I say? I have tried so many solutions honestly, and none have solved it, hence why I ask. As a reminder:

Scenario (press space once read) -- Single-target word (is it real or nonword?) --  (sometimes) a comprehension question (yes/no response).

For the majority of comprehension questions, the correct key mappings (via list as you advised) indeed works! For example, when I run the experiment, then check my raw data/output, under ‘correct’ column, the binary number (e.g. 0 or 1) corresponds to what was authentically correct, respectively. Either ‘E’ for yes or ‘I’ for no. However, those portion of questions specifically requiring a no (I) response, for some reason the ‘correct’ column inverts what the correct answer ought to be, for the following below comprehension question items:

ITEM 30 (answer = I)
ITEM 3 (answer = I)
ITEM 39 (answer = I)
ITEM 23 (answer = I)
ITEM 6 (answer = I)
ITEM 12 (answer = I)
ITEM 5 (answer = I)
ITEM 15 (answer = I)
ITEM 33 (answer = I)
ITEM 21 (answer = I)
ITEM 28 (answer = I)
ITEM 3 (answer = I)

e.g. for item 30, the question is ‘did you take a Chinese course?’. The answer to this is I/no. Yet in the binary (correct column), it produces a 0 if you press I, and a 1 if you press E! (hence invert). Bizarre no? And it is systematic for these ones above (I have doubly checked and must know them by heart by now lol). The yes/E questions work fine (e.g. binary 0, 1 responds equally correctly to an incorrect/correct response, respectively).
I tried changing key scans, re-typing items, swapping the correct keys for those select items, and much more. Nothing has done the trick at all. I paste the script here, and the file in case you wish to run so u can see the raw data. I’m so baffled, literally. The only thing I can now think of is something to do with lists, or making more lists or values but maybe I am wrong.

Thank you so much as always, I very much appreciate your help. I made all this script myself lol, and genuinely understand it, just so baffled by why correct output is systematically doing this for i/no responses.

*****************
Press spacebar onces you have read a scenario
Press E for YES or I for no

When a single word is shown, participants must decide whether it is a real word or nonword via E or I keypress
When answer comprehension questions, the same E and I responsea are required.

filled with '50'/no correct key, (50 was taken at random given these trials are skipped)

EXPRESSIONS
*****************
We are defining expressions here in order to collect key summary data further down, such as mean, medians, SD etc. These apply to each of the single-target word types
namely, positive, negative and nonwords.
*****************
<expressions>
/ PropCorrect = list.overallaccuracy.mean
/ MeanRT = list.overallRT.mean
/ STD = list.overallRT.standarddeviation
/ MedianRT = list.overallRT.median

/PropCorrect_Positiveword = list.positiveword.mean

/ STD_Positiveword = list.positiveword_correctRT.standarddeviation
/ MedianRT_Positiveword = list.positiveword_correctRT.median
</expressions>

*****************
VALUES
*****************
/completed:                0 = script was not completed; 1 = script was completed (all conditions run)

*****************
SUMMARY DATA
*****************
Collect key data based on the expressions above, such as mean, median and SD data from each type of word trial (e.g. positive, negative, mnonword).
Both mean and median have been included. Previous studies (e.g. Feng, Hirsch etc) have opted for median since 'the reaction time medians were used in this study instead of means because
reaction time means are positively skewed and medians are much more insensitive to the skew of the distribution (Baayen & Milin, 2010) and in keeping
with previous research using the LDT task (Hirsch & Mathews, 1997, 2000;
Hirsch, Mathews, Clark, Williams, & Morrison 2003; Hirsch et al., 2006).
*****************
<summarydata>
/columns = (script.startdate, script.starttime, script.subjectid, script.groupid, script.elapsedtime, computer.platform, values.completed,

expressions.PropCorrect_Positiveword, expressions.MeanRT_Positiveword, expressions.STD_Positiveword, expressions.MedianRT_Positiveword)
/ separatefiles = true

Try setting

<list correctkeys>
/ items = (18, 18, 23, 18, 23, 23, 18, 50, 50, 50, 18, 23, 18, 50, 23, 18, 50, 18, 50, 50, 23, 50, 23, 50, 50, 18, 50, 23, 18, 23, 50, 50, 23, 18, 50, 50, 50, 50, 23, 18)
/ selectionmode = text.scenario.currentindex
</list>

and that should hopefully do the trick.

It worked! It did indeed do the trick! (I knew it would be a minor correction, argh), I honestly can't thank you enough...
This will be it from me for a good while now lol.

Kindest Regards
