Hi, 

i'm new to Inquisit and first I'd like to thank Milisecond for providing us with such a usefull Tool for research.

i'm having a hard time extending the AAT-Task from the Task Library. This Task can be found here: http://www.millisecond.com/download/library/AAT/
The only change to the Design of Wiers et al is, that we want to use 6 categories with each 8 Stimuli (instead of 4 categories with 10 Stimuli).  I was able to change the Stimuli and categories. I did alter total trials, create new branches, new trials, Stimcats..... My Problem is now that i can't figure out how to alter the sequence generator to work with the 6 categories.I'm thankful for any suggestions.

In the following task, you will be presented images either in landscape or portrait format.
^^Ihre Aufgabe ist es die Maus
^* zu sich zu zu zihen, wenn das Bild <%values.format1%> erscheint
^                                        (aka move the mouse cursor DOWN)
^*  von sich weg zu drücken, wenn das Bild <%values.format2%> erscheint 
^                                        (aka move the mouse cursor UP)
^^=> Wenn Sie die Maus von sich weg bewegen wird das Bild verkleinert.
^=> Wenn Sie die Maus zu sich hin zihen wird das Bild größer.
^^^Sie müssen die Maus immer bis zum Bildschirmrand bewegen. 
^^Anschließend werden sie aufgefordert die Maus wieder zur BIldschormmitte auszurichten und auf das X zu klicken.
^^Nachdem SIe auf das X geklick haben erscheint ein neues Bild
^^Drücken Sie auf das Feld um den Testdurchlauf zu starten.

TRIAL SEQUENCE GENERATION  CODE:
**************************************************************************************************************
**************************************************************************************************************
The trial sequence generation code generates a sequence of trials that fulfills the following
constraints:
1) 10 stimuli of category 1 in Format A (=1), 10 stimuli of category 1 in Format B (=2),
10 stimuli of category 2 in Format A (=3), 10 stimuli of category 1 in Format B (=4),
10 stimuli of category 3 in Format A (=5), 10 stimuli of category 1 in Format B (=6),
10 stimuli of category 4 in Format A (=7), 10 stimuli of category 1 in Format B (=8),
2) no more than three consecutive stimuli of the same category
3) no more than three consecutive stimuli of the same format

the sequences produced look something like this:
86854627681534427238341865316174854225166758252358517483251343227374137614617876

NOTE:
!!!! The time to generate the appropriate sequence will differ between participants.
Two alternatives are:
1) pregenerated sequences.
For example, you could generate 100 of these sequences (run this code in a separate script),
store the sequences in an item element and select randomly from these sequences for each
participant.
2) run the experiment with simple random sampling 
(without replacement) without paying attention to the added constraints 
regarding category/format repetitions.

This trialsequence algorithm is a simple, brute-force method that may 
reach its limits if more conditions/trials are added. In this case,
a new algorithm may have to be written or any of the two alternatives has
to be used.

Look at how a generated sequence as stored in values.sequence looks like. An example is right there in the script's comments:

"the sequences produced look something like this:
86854627681534427238341865316174854225166758252358517483251343227374137614617876"

trial.aat_start the pulls *a single digit* out of that long string and increases an index value by one:

<trial AAT_start>
/ ontrialbegin = [values.nextstimulus = substring(values.sequence, values.index, 1);
                        values.index += 1]
[...]
</trial>

Now, obviously, that'll work fine as long as you're in the single-digit range, i.e. there a no more than 9 categories / versions as in

<list stimcats>
/ items = (
1,1,1,1,1,1,1,1,1,1,
2,2,2,2,2,2,2,2,2,2,
3,3,3,3,3,3,3,3,3,3,
4,4,4,4,4,4,4,4,4,4,
5,5,5,5,5,5,5,5,5,5,
6,6,6,6,6,6,6,6,6,6,
7,7,7,7,7,7,7,7,7,7,
8,8,8,8,8,8,8,8,8,8)
/ replace = false
</list>

You, however, break into the two-digit realm:

<list stimcats>
/ items = (
1,1,1,1,1,1,1,1,
2,2,2,2,2,2,2,2,
3,3,3,3,3,3,3,3,
4,4,4,4,4,4,4,4,
5,5,5,5,5,5,5,5,
6,6,6,6,6,6,6,6,
7,7,7,7,7,7,7,7,
8,8,8,8,8,8,8,8,
9,9,9,9,9,9,9,9,
10,10,10,10,10,10,10,10,
11,11,11,11,11,11,11,11,
12,12,12,12,12,12,12,12)
/ replace = false
</list>

Now, suppose, one of the 12s is pulled from the list and added to values.sequence in the course of sequence generation. values.sequence will thus contain the following

"...12..."

To <trial AAT_start> this *does not* indicate "category 12". Instead it is interpreted as "category 1" followed by "category 2" as per the statement

/ ontrialbegin = [values.nextstimulus = substring(values.sequence, values.index, 1);
                        values.index += 1]

already discussed above. A further problem, of course, is posed by the 10s in your <list>, meaning "category 1" followed by "category 0". There is no "category 0", though.

So, what you ought to do, is (a) extend everything to two digits

<list stimcats>
/ items = (
01,01,01,01,01,01,01,01,
02,02,02,02,02,02,02,02,
...
11,11,11,11,11,11,11,11,
12,12,12,12,12,12,12,12)
/ replace = false
</list>

such that the resulting values.sequence e.g. reads

"...100302..."

meaning category 10, followed by category 3, followed by category 2 and (b) adjust the logic throughout the script accordingly

/ ontrialbegin = [values.nextstimulus = substring(values.sequence, values.index, 2);
                        values.index += 2]

etc.

A personal request, if I may: Please do not paste lengthy syntax excerpts or full scripts into a post's body. It makes those posts extremely hard to follow throuh and work with. Please use the forum's file attachment facilities instead. Thank you.

the sequence generator doesnt seem to stop.

The algorithm has its limits (as indicated in the script's comments):

"This trialsequence algorithm is a simple, brute-force method that may reach its limits if more conditions/trials are added."

Basically, if at a given point the generated sequence so far doesn't satisfy the various constraints imposed, the entire generation process will be restarted from scratch. The more complex things get (more categories, more constraints), the longer this process will take and the likelier it is to fail (i.e. to not converge on a valid result). Constrained randomization is a hard problem (c.f. https://www.millisecond.com/forums/Topic6419.aspx). In this case, you should consider the alternatives indicated in the comments:

"
NOTE:
!!!! The time to generate the appropriate sequence will differ between participants.
Two alternatives are:
1) pregenerated sequences.
For example, you could generate 100 of these sequences (run this code in a separate script),
store the sequences in an item element and select randomly from these sequences for each
participant.
2) run the experiment with simple random sampling 
(without replacement) without paying attention to the added constraints 
regarding category/format repetitions."

Hi, 

it's running again thanks but now there are only about 10 testtrials. I'll atach the file. I havent programmed in 2 years and would appreciate any help. Thank you.

#1:
<values>
/totaltrialcount = 80
[...]
</values>

#2:
<trial selectnumber>
[...]
/ branch = [if (values.index < values.totaltrialcount) trial.selectnumber ]
</trial>

You should also (a) enable the debug /branch included in the script's comments for the above <trial>

"Debug:
/ branch = [if (values.index < values.totaltrialcount) trial.selectnumber else trial.showsequence]"

to view the generated sequence and (b) use CTRL+D extensively to review the state of the various variables involved.

hi,

looking at the sequence i can see that its still generated in the one digit format. This might be the problem. Where can i find the procedure that is causing the digitlength?

Thank you for the help... I hope i am not asking for too much help on here.

There are various issues with your code (and I'm not sure I've caught them all; when in doubt, go back to the original script and study the code for <trial selectnumber> thoroughly until you fully understand how it works / what it does; only then start re-adding your modifications, i.e. the extension to additional categories). Anyway, review the attached file to which I've added a bunch of debug stuff allowing you to observe sequence generation as it happens. Note that you are going to run into issues re. format (A/B) runs due to the increased number of categories. You should consider increasing the cutoff value (currently < 4).

EDIT NOTE: Uploaded wrong attachment. Fixed now.
