How to code stimuluslocked EEG-/TTL-triggers in Inquisit

alicealice — Tue, 07 May 2024 12:39:23 GMT

Hello there,

I plan to conduct an IAT and want to code EEG-Triggers when certain keys are pressed ("responselocked triggers") but also when stimuli appear ("stimuluslocked triggers").
I managed to code responselocked triggers but am a bit lost when it comes to the stimuluslocked triggers. For clarification: Everytime an item from the targetA, targetB, attributeA, attributeB "list" (not coded) appears on the screen, I want a trigger to be sent. Same for an errorsignal which is indicated by a red X, when the task has not been done correctly.
I would be so so grateful if anyone could help me with this matter!
There are several ideas I carried out but did not manage to suceed: creating values, branches, lists to use the "if"-function, as in: if item.targetA (port.targetAleft), so that everytime an item from the target A list appears, a port signal for that very target is triggered.

You can find my code attached.
Please focus on the trial "targetAleft" in the trial section to see what my current status is.

Another question regarding the 8-bits in the port.signal --> can the sequence be allocated randomly, as long as there is a 1 somwhere in the sequence? If not, what is the specific meaning of the quantity of 1s/0s?

Thank you very, very much!

Warmest Regards,
Alice

BACKGROUND INFO

The Implicit Association Task (Greenwald, McGhee, & Schwartz, 1998) is a widely-used cognitive-behavioral paradigm
that measures the strength of automatic (implicit) associations between concepts in people’s minds relying
on latency measures in a simple sorting task.

The strength of an association between concepts is measured by the standardized mean difference score of
the 'hypothesis-inconsistent' pairings and 'hypothesis-consistent' pairings (d-score) (Greenwald, Nosek, & Banaji, 2003).
In general, the higher the d-score the stronger is the association between the 'hypothesis-consistent' pairings
(decided by researchers). Negative d-scores suggest a stronger association between the 'hypothesis-inconsistent' pairings.

Inquisit calculates d-scores using the improved scoring algorithm as described in Greenwald et al (2003).
Error trials are handled by requiring respondents to correct their responses according to recommendation (p.214).

D-scores obtained with this script:
Positive d-scores: support a stronger association between 'Forgiveness-Me' and 'Revenge-Others' than for the opposite pairings
Negative d-scores: support a stronger association between 'Revenge-Me' and 'Forgiveness-Others' than for the opposite pairings

                                             *Task*
Participants are asked to categorize attributes (e.g. "me"; "they") and target items (e.g "mercy" vs. "retaliation")
into predetermined categories via keystroke presses. The basic task is to press a left key (E) if an item (e.g. "me")
belongs to the category presented on the left (e.g. "ME") and to press the right key (I) if the word (e.g. "they")
belongs to the category ("OTHERS") presented on the right.
For practice, participants sort items into the target categories "Forgiveness vs. Revenge" and the attribute categories
"ME vs. OTHERS".
For the test, participants are asked to sort categories into the paired/combined categories (e.g.
"Forgiveness OR ME" on the left vs. "Revenge OR OTEHRS" on the right). Pairings are reversed for a second test
(e.g. "Revenge OR ME" on the left vs. "Forgiveness OR OTHERS" on the right). Order is counterbalanced by groupnumber.

DATA FILE INFORMATION:
The default data stored in the data files are:

(1) Raw data file: 'ForgivenessIAT_raw*.iqdat' (a separate file for each participant)

build:                            Inquisit build
computer.platform:                the platform the script was run on
date, time, subject, group:        date and time script was run with the current subject/groupnumber
                                        Note: group1/group2 counterbalance the order in which the pairings are run
blockcode, blocknum:            the name and number of the current block
trialcode, trialnum:             the name and number of the currently recorded trial
                                    (Note: not all trials that are run might record data; by default data is collected unless /recorddata = false is set for a particular trial/block)
response:                        the final trial response (scancodes of the keys pressed)
                                        Note: script saves the final and -by design- correct response
correct:                        the accuracy of the initial response
                                        0 = initial response was incorrect and needed to be corrected
                                        1 = initial response is correct
latency:                        the latency of the final (correct) response in ms
stimulusnumber:                    the number of the current stimulus
stimulusitem:                    the currently presented item

/ percentcorrect:           the overall percent correct score of initial responses of test trials of D-score qualifying latencies

(2) Summary data file: 'ForgivenessIAT_summary*.iqdat' (a separate file for each participant)

script.startdate:                date script was run
script.starttime:                time script was started
script.subjectid:                subject id number
script.groupid:                    group id number
script.elapsedtime:                time it took to run script (in ms)
computer.platform:                the platform the script was run on
/completed:                        0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)

EXPERIMENTAL SET-UP

Hypothesis-consistent pairings vs. hypothesis-inconsistent pairings; tested within-subjects in a blocked format
=> order is counterbalanced by groupnumber assignment
odd groupnumbers run: consistent - inconconsistent pairings
even groupnumbers run: inconsistent - consistent pairings

Block Sequence:
1. Target Category sorting training
2. Attribute sorting training
3. 1. Test Block of hypothesis-consistent* pairings with 20 trials (half the participant start with inconsistent pairings)
4. 2. Test Block of hypothesis-consistent pairings with 40 trials
5. Target Category sorting training with targets switching sides
6. 1. Test Block of hypothesis-inconsistent pairings with 20 trials
7. 2. Test Block of hypothesis-inconsistent pairings with 40 trials

In all Test Blocks:
* attributes and targets alternate
* attributes as well as targets are randomly selected without replacement

Trial Sequence:
Target -> until correct response -> ISI: 250ms (default)-> Target....

STIMULI
Stimuli can be edited under section Editable Stimuli

INSTRUCTIONS

* start instruction page is provided as an html page. It automatically adapts to different images and category labels UNLESS
the number of attributes and/or targets have been changed. In this case, changes have to be
made to file "intro_iat.htm", so that the correct number of items are presented in the overview table.

Example: instead of 8 words for target A, only 5 should be presented:

in file "intro_iat.htm":
change:
            <td><%item.targetA.item(1)%>, <%item.targetA.item(2)%>, <%item.targetA.item(3)%>, <%item.targetA.item(4)%>,
                <%item.targetA.item(5)%>, <%item.targetA.item(6)%>, <%item.targetA.item(7)%>, <%item.targetA.item(8)%>
            </td>

To:
            <td><%item.targetA.item(1)%>, <%item.targetA.item(2)%>, <%item.targetA.item(3)%>, <%item.targetA.item(4)%>,
                <%item.targetA.item(5)%>
            </td>

* item.instructions under section 'Editable Instructions' contains the the trial instructions
The instructions adapt automatically if different attributes and targets are used.

EDITABLE CODE:
check below for (relatively) easily editable parameters, stimuli, instructions etc.
Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.

The parameters you can change are:

/showsummaryfeedback:        set parameter showsummaryfeedback = true to display summary feedback to participants at the end (default)
                            set parameter showsummaryfeedback = false if no summary feedback should be presented to participants
/ISI:                        interstimulus interval (in ms) (default: 250ms)

BACKGROUND INFO

The Implicit Association Task (Greenwald, McGhee, & Schwartz, 1998) is a widely-used cognitive-behavioral paradigm
that measures the strength of automatic (implicit) associations between concepts in people’s minds relying
on latency measures in a simple sorting task.

The strength of an association between concepts is measured by the standardized mean difference score of
the 'hypothesis-inconsistent' pairings and 'hypothesis-consistent' pairings (d-score) (Greenwald, Nosek, & Banaji, 2003).
In general, the higher the d-score the stronger is the association between the 'hypothesis-consistent' pairings
(decided by researchers). Negative d-scores suggest a stronger association between the 'hypothesis-inconsistent' pairings.

Inquisit calculates d-scores using the improved scoring algorithm as described in Greenwald et al (2003).
Error trials are handled by requiring respondents to correct their responses according to recommendation (p.214).

D-scores obtained with this script:
Positive d-scores: support a stronger association between 'Forgiveness-Me' and 'Revenge-Others' than for the opposite pairings
Negative d-scores: support a stronger association between 'Revenge-Me' and 'Forgiveness-Others' than for the opposite pairings

                                             *Task*
Participants are asked to categorize attributes (e.g. "me"; "they") and target items (e.g "mercy" vs. "retaliation")
into predetermined categories via keystroke presses. The basic task is to press a left key (E) if an item (e.g. "me")
belongs to the category presented on the left (e.g. "ME") and to press the right key (I) if the word (e.g. "they")
belongs to the category ("OTHERS") presented on the right.
For practice, participants sort items into the target categories "Forgiveness vs. Revenge" and the attribute categories
"ME vs. OTHERS".
For the test, participants are asked to sort categories into the paired/combined categories (e.g.
"Forgiveness OR ME" on the left vs. "Revenge OR OTEHRS" on the right). Pairings are reversed for a second test
(e.g. "Revenge OR ME" on the left vs. "Forgiveness OR OTHERS" on the right). Order is counterbalanced by groupnumber.

DATA FILE INFORMATION:
The default data stored in the data files are:

(1) Raw data file: 'ForgivenessIAT_raw*.iqdat' (a separate file for each participant)

build:                            Inquisit build
computer.platform:                the platform the script was run on
date, time, subject, group:        date and time script was run with the current subject/groupnumber
                                        Note: group1/group2 counterbalance the order in which the pairings are run
blockcode, blocknum:            the name and number of the current block
trialcode, trialnum:             the name and number of the currently recorded trial
                                    (Note: not all trials that are run might record data; by default data is collected unless /recorddata = false is set for a particular trial/block)
response:                        the final trial response (scancodes of the keys pressed)
                                        Note: script saves the final and -by design- correct response
correct:                        the accuracy of the initial response
                                        0 = initial response was incorrect and needed to be corrected
                                        1 = initial response is correct
latency:                        the latency of the final (correct) response in ms
stimulusnumber:                    the number of the current stimulus
stimulusitem:                    the currently presented item
expressions.da:                    d-score of the first short blocks
expressions.db:                    d-score of the second long blocks
expressions.d:                    overall d-score (non-weighted mean of the 2 d-scores)
/ percentcorrect:           the overall percent correct score of initial responses of test trials of D-score qualifying latencies

(2) Summary data file: 'ForgivenessIAT_summary*.iqdat' (a separate file for each participant)

EXPERIMENTAL SET-UP

Hypothesis-consistent pairings vs. hypothesis-inconsistent pairings; tested within-subjects in a blocked format
=> order is counterbalanced by groupnumber assignment
odd groupnumbers run: consistent - inconconsistent pairings
even groupnumbers run: inconsistent - consistent pairings

Block Sequence:
1. Target Category sorting training
2. Attribute sorting training
3. 1. Test Block of hypothesis-consistent* pairings with 20 trials (half the participant start with inconsistent pairings)
4. 2. Test Block of hypothesis-consistent pairings with 40 trials
5. Target Category sorting training with targets switching sides
6. 1. Test Block of hypothesis-inconsistent pairings with 20 trials
7. 2. Test Block of hypothesis-inconsistent pairings with 40 trials

In all Test Blocks:
* attributes and targets alternate
* attributes as well as targets are randomly selected without replacement

Trial Sequence:
Target -> until correct response -> ISI: 250ms (default)-> Target....

STIMULI
Stimuli can be edited under section Editable Stimuli

INSTRUCTIONS

* start instruction page is provided as an html page. It automatically adapts to different images and category labels UNLESS
the number of attributes and/or targets have been changed. In this case, changes have to be
made to file "intro_iat.htm", so that the correct number of items are presented in the overview table.

Example: instead of 8 words for target A, only 5 should be presented:

in file "intro_iat.htm":
change:
            <td><%item.targetA.item(1)%>, <%item.targetA.item(2)%>, <%item.targetA.item(3)%>, <%item.targetA.item(4)%>,
                <%item.targetA.item(5)%>, <%item.targetA.item(6)%>, <%item.targetA.item(7)%>, <%item.targetA.item(8)%>
            </td>

To:
            <td><%item.targetA.item(1)%>, <%item.targetA.item(2)%>, <%item.targetA.item(3)%>, <%item.targetA.item(4)%>,
                <%item.targetA.item(5)%>
            </td>

* item.instructions under section 'Editable Instructions' contains the the trial instructions
The instructions adapt automatically if different attributes and targets are used.

EDITABLE CODE:
check below for (relatively) easily editable parameters, stimuli, instructions etc.
Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.

The parameters you can change are:

/showsummaryfeedback:        set parameter showsummaryfeedback = true to display summary feedback to participants at the end (default)
                            set parameter showsummaryfeedback = false if no summary feedback should be presented to participants
/ISI:                        interstimulus interval (in ms) (default: 250ms)

BACKGROUND INFO

The Implicit Association Task (Greenwald, McGhee, & Schwartz, 1998) is a widely-used cognitive-behavioral paradigm
that measures the strength of automatic (implicit) associations between concepts in people’s minds relying
on latency measures in a simple sorting task.

The strength of an association between concepts is measured by the standardized mean difference score of
the 'hypothesis-inconsistent' pairings and 'hypothesis-consistent' pairings (d-score) (Greenwald, Nosek, & Banaji, 2003).
In general, the higher the d-score the stronger is the association between the 'hypothesis-consistent' pairings
(decided by researchers). Negative d-scores suggest a stronger association between the 'hypothesis-inconsistent' pairings.

Inquisit calculates d-scores using the improved scoring algorithm as described in Greenwald et al (2003).
Error trials are handled by requiring respondents to correct their responses according to recommendation (p.214).

D-scores obtained with this script:
Positive d-scores: support a stronger association between 'Forgiveness-Me' and 'Revenge-Others' than for the opposite pairings
Negative d-scores: support a stronger association between 'Revenge-Me' and 'Forgiveness-Others' than for the opposite pairings

                                             *Task*
Participants are asked to categorize attributes (e.g. "me"; "they") and target items (e.g "mercy" vs. "retaliation")
into predetermined categories via keystroke presses. The basic task is to press a left key (E) if an item (e.g. "me")
belongs to the category presented on the left (e.g. "ME") and to press the right key (I) if the word (e.g. "they")
belongs to the category ("OTHERS") presented on the right.
For practice, participants sort items into the target categories "Forgiveness vs. Revenge" and the attribute categories
"ME vs. OTHERS".
For the test, participants are asked to sort categories into the paired/combined categories (e.g.
"Forgiveness OR ME" on the left vs. "Revenge OR OTEHRS" on the right). Pairings are reversed for a second test
(e.g. "Revenge OR ME" on the left vs. "Forgiveness OR OTHERS" on the right). Order is counterbalanced by groupnumber.

DATA FILE INFORMATION:
The default data stored in the data files are:

(1) Raw data file: 'ForgivenessIAT_raw*.iqdat' (a separate file for each participant)

build:                            Inquisit build
computer.platform:                the platform the script was run on
date, time, subject, group:        date and time script was run with the current subject/groupnumber
                                        Note: group1/group2 counterbalance the order in which the pairings are run
blockcode, blocknum:            the name and number of the current block
trialcode, trialnum:             the name and number of the currently recorded trial
                                    (Note: not all trials that are run might record data; by default data is collected unless /recorddata = false is set for a particular trial/block)
response:                        the final trial response (scancodes of the keys pressed)
                                        Note: script saves the final and -by design- correct response
correct:                        the accuracy of the initial response
                                        0 = initial response was incorrect and needed to be corrected
                                        1 = initial response is correct
latency:                        the latency of the final (correct) response in ms
stimulusnumber:                    the number of the current stimulus
stimulusitem:                    the currently presented item
expressions.da:                    d-score of the first short blocks
expressions.db:                    d-score of the second long blocks
expressions.d:                    overall d-score (non-weighted mean of the 2 d-scores)
/ percentcorrect:           the overall percent correct score of initial responses of test trials of D-score qualifying latencies

(2) Summary data file: 'ForgivenessIAT_summary*.iqdat' (a separate file for each participant)

script.startdate:                date script was run
script.starttime:                time script was started
script.subjectid:                subject id number
script.groupid:                    group id number
script.elapsedtime:                time it took to run script (in ms)
computer.platform:                the platform the script was run on
/completed:                        0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)
expressions.da:                    d-score of the first blocks
expressions.db:                    d-score of the second blocks
expressions.d:                    overall d-score
/ percentcorrect:           the overall percent correct score of initial responses of test trials of D-score qualifying latencies

EXPERIMENTAL SET-UP

Hypothesis-consistent pairings vs. hypothesis-inconsistent pairings; tested within-subjects in a blocked format
=> order is counterbalanced by groupnumber assignment
odd groupnumbers run: consistent - inconconsistent pairings
even groupnumbers run: inconsistent - consistent pairings

Block Sequence:
1. Target Category sorting training
2. Attribute sorting training
3. 1. Test Block of hypothesis-consistent* pairings with 20 trials (half the participant start with inconsistent pairings)
4. 2. Test Block of hypothesis-consistent pairings with 40 trials
5. Target Category sorting training with targets switching sides
6. 1. Test Block of hypothesis-inconsistent pairings with 20 trials
7. 2. Test Block of hypothesis-inconsistent pairings with 40 trials

In all Test Blocks:
* attributes and targets alternate
* attributes as well as targets are randomly selected without replacement

Trial Sequence:
Target -> until correct response -> ISI: 250ms (default)-> Target....

STIMULI
Stimuli can be edited under section Editable Stimuli

INSTRUCTIONS

* start instruction page is provided as an html page. It automatically adapts to different images and category labels UNLESS
the number of attributes and/or targets have been changed. In this case, changes have to be
made to file "intro_iat.htm", so that the correct number of items are presented in the overview table.

Example: instead of 8 words for target A, only 5 should be presented:

in file "intro_iat.htm":
change:
            <td><%item.targetA.item(1)%>, <%item.targetA.item(2)%>, <%item.targetA.item(3)%>, <%item.targetA.item(4)%>,
                <%item.targetA.item(5)%>, <%item.targetA.item(6)%>, <%item.targetA.item(7)%>, <%item.targetA.item(8)%>
            </td>

To:
            <td><%item.targetA.item(1)%>, <%item.targetA.item(2)%>, <%item.targetA.item(3)%>, <%item.targetA.item(4)%>,
                <%item.targetA.item(5)%>
            </td>

* item.instructions under section 'Editable Instructions' contains the the trial instructions
The instructions adapt automatically if different attributes and targets are used.

EDITABLE CODE:
check below for (relatively) easily editable parameters, stimuli, instructions etc.
Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.

The parameters you can change are:

/showsummaryfeedback:        set parameter showsummaryfeedback = true to display summary feedback to participants at the end (default)
                            set parameter showsummaryfeedback = false if no summary feedback should be presented to participants
/ISI:                        interstimulus interval (in ms) (default: 250ms)

<port> elements are stimulus elements like any other -- <text>, <picture>, etc. -- so you simply "display" your <port> stimuli at the time you need to in the <trial>s' /stimulusframes.

You have 8 bits available, binary digits. This means, in terms of decimal values, that you can represent 256 different values, from 0 (no signal raised, "00000000") to 255 ("11111111").

You'll want to read https://www.millisecond.com/support/docs/v5/html/howto/howtosendport.htm in the documentation and if you want a fleshed-out example to look at, take the Auditory Oddball task available in the library: https://www.millisecond.com/download/library/oddball

Dear Dave,

thank you so much for your quick response, really appreciate it!
Thank you for the examples, I already read through quite some stuff, including the given links.
My problem is, that even though I place my eegtrigger in the stimulusframe, it does not elicit a trigger when the words of the referenced item category are shown. An example would be the code in 'trial target a'.
Do you have an idea what i am doing wrong?
Thank you!
[/quote]

* 'trial target a left' - sorry, i am new to inquisit and read through everything i could found for the past 8h, hence my concentration level is a bit low :)

Also: since my responsetriggers are working, i am wondering if not the registered eegtriggers in the responseframe are triggering the eeg signal, whenever a correct response is given?
TThank you!!
[/quote]

<trial targetAleft>
/ validresponse = ("E", "I")
/ correctresponse = ("E")
/ stimulusframes = [1 = targetA, errorReminder, eegtargetAleft]
/ branch=[if (item.targetA) port.eegtargetAleft]
/ responsemessage = (" ", responsesignal, 0)
/ posttrialpause = parameters.ISI
</trial>

displays

<port eegtargetAleft>
/ port = LPT1
/ subport = data
/ items = ("00010000")
</port>

in its first frame, at the same time as the targetA stimulus.

/ branch=[if (item.targetA) port.eegtargetAleft]

makes no sense and does nothing, and

/ responsemessage = (" ", responsesignal, 0)

is simply wrong. The space bar is not a response that occurs in this trial. The responses can be "E" or "I" respectively.
[/quote]

Try something like

[code]
<trial targetAleft>
/ validresponse = ("E", "I")
/ correctresponse = ("E")
/ stimulustimes = [0 = targetA, errorReminder, eegtargetAleft; 50 = eegallbitstolow]
/ responseinterrupt = frames
/ beginresponsetime = 0
/ responsemessage = ("E", responsesignal, 50)
/ responsemessage = ("I", eegerrorsignal, 50)
/ posttrialpause = parameters.ISI
</trial>

<port eegallbitstolow>
/ port = LPT1
/ subport = data
/ items = ("00000000")
</port>

<port eegtargetAleft>
/ port = LPT1
/ subport = data
/ items = ("00010000")
</port>

<port responsesignal>
/ port = LPT1
/ subport = data
/ items = ("00000011")
</port>

<port eegerrorsignal>
/port = LPT1
/ subport = data
/items = ("01000000")
</port> [/code]

This will raise the "targetA" trigger at the onset of the target A stimulus and it will turn that trigger off 50ms later to avoid cross-talk with the response triggers.

When "E" (the correct response in this trial) is pressed, the responsesignal trigger will be raised. When "I" is pressed, the errorsignal trigger will be raised.

hey dave, just a heads up: your script works perfectly fine and i am beyond grateful for your support!
thanks so much!

<port> elements are stimulus elements like any other -- <text>, <picture>, etc. -- so you simply "display" your <port> stimuli at the time you need to in the <trial>s' /stimulusframes.

You have 8 bits available, binary digits. This means, in terms of decimal values, that you can represent 256 different values, from 0 (no signal raised, "00000000") to 255 ("11111111").

You'll want to read https://www.millisecond.com/support/docs/v5/html/howto/howtosendport.htm in the documentation and if you want a fleshed-out example to look at, take the Auditory Oddball task available in the library: https://www.millisecond.com/download/library/oddball

Dear Dave,

thank you so much for your quick response, really appreciate it!
Thank you for the examples, I already read through quite some stuff, including the given links.
My problem is, that even though I place my eegtrigger in the stimulusframe, it does not elicit a trigger when the words of the referenced item category are shown. An example would be the code in 'trial target a'.
Do you have an idea what i am doing wrong?
Thank you!

* 'trial target a left' - sorry, i am new to inquisit and read through everything i could found for the past 8h, hence my concentration level is a bit low :)

Also: since my responsetriggers are working, i am wondering if not the registered eegtriggers in the responseframe are triggering the eeg signal, whenever a correct response is given?
TThank you!!
