pointer for lists

nrouhani — Wed, 01 Jun 2022 01:21:42 GMT

hi,

i have a pretty complicated experiment that has many conditions and counterbalancing. is it possible to have a pointer for lists?
so for example if i have the below list and would like it to be called in block 1, could i have something like list.block1 = list.lr_2080?
<list lr_2080>
/ items = (2,1,1,2,2,1,2,1,1,2,2,1,2,1,1,2,2,1,2,2,1,1,2,1,1,2,2,1,2,1)
/ selectionmode = sequence
</list>

thank you!

You can have a list of lists, however, and select whatever list you want via a variable.

<list list_of_lists>
/ items = (list.a.nextvalue, list.b.nextvalue, list.c.nextvalue)
/ selectionmode = values.listnumber
</list>

with values.listnumber = 1 for list A,
values.listnumber = 2 for list B, and
values.listnumber = 3 for list C.

You simply always sample from list.list_of_lists per its nextvalue.

[code]<item myitems>
/ 1 = "A1"
/ 2 = "A2"
/ 3 = "A3"

/ 4 = "B1"
/ 5 = "B2"
/ 6 = "B3"

/ 7 = "C1"
/ 8 = "C2"
/ 9 = "C3"
</item>

<text mytext>
/ items = myitems
/ select = values.itemnumber
</text>

<list a>
/ items = (1,2,3)
/ selectionmode = sequence
</list>

<list b>
/ items = (4,5,6)
/ selectionmode = sequence
</list>

<list c>
/ items = (7,8,9)
/ selectionmode = sequence
</list>

<list list_of_lists>
/ items = (list.a.nextvalue, list.b.nextvalue, list.c.nextvalue)
/ selectionmode = values.listnumber
</list>

<values>
/ itemnumber = 0
/ listnumber = 0
</values>

<block example>
/ onblockbegin = [
    values.listnumber = 2; // set to 1, 2 or 3 depending on the list you want to run
]
/ trials = [1-3 = mytrial]
</block>

<trial mytrial>
/ ontrialbegin = [
    values.itemnumber = list.list_of_lists.nextvalue;
]
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>[/code]
[/quote]

thank you! could i use this list of lists across blocks? (i.e., would the values reset at each block?)
[/quote]

could each block iterate through the items within the list of lists (by using nextvalue)?
[/quote]

This does not clear anything up -- the "items within the list of lists" are lists. It's not clear what you want to iterate through.
Please state clearly what exactly you want to do. Then I can answer your question.

do i have to manually set in 1,2,3 when calling up the list of lists in each block or can i iterate through the items (that i am aware are also lists).

You can set values.listnumber in whichever way you want

Here's an extended example implementing three conditions -- each running the three lists in different orders:

[code]<item myitems>
/ 1 = "A1"
/ 2 = "A2"
/ 3 = "A3"

/ 4 = "B1"
/ 5 = "B2"
/ 6 = "B3"

/ 7 = "C1"
/ 8 = "C2"
/ 9 = "C3"
</item>

<text mytext>
/ items = myitems
/ select = values.itemnumber
</text>

<list a>
/ items = (1,2,3)
/ selectionmode = sequence
</list>

<list b>
/ items = (4,5,6)
/ selectionmode = sequence
</list>

<list c>
/ items = (7,8,9)
/ selectionmode = sequence
</list>

<list list_of_lists>
/ items = (list.a.nextvalue, list.b.nextvalue, list.c.nextvalue)
/ selectionmode = values.listnumber
</list>

<values>
/ itemnumber = 0
/ listnumber = 0
/ listorder = 0
</values>

<block example>
/ onblockbegin = [
    values.listnumber = list.listorders.nextvalue;
]
/ trials = [1-3 = mytrial]
</block>

<trial mytrial>
/ ontrialbegin = [
    values.itemnumber = list.list_of_lists.nextvalue;
]
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>

<expt>
/ onexptbegin = [
    values.listorder = 1;
]
/ groups = (1 of 3)
/ blocks = [1-3 = example]
</expt>

<expt>
/ onexptbegin = [
    values.listorder = 2;
]
/ groups = (2 of 3)
/ blocks = [1-3 = example]
</expt>

<expt>
/ onexptbegin = [
    values.listorder = 3;
]
/ groups = (3 of 3)
/ blocks = [1-3 = example]
</expt>

<list listorders>
/ items = (list.order1.nextvalue, list.order2.nextvalue, list.order3.nextvalue)
/ selectionmode = values.listorder
</list>

<list order1>
/ items = (1,2,3)
/ selectionmode = sequence
</list>

<list order2>

thank you! could i use this list of lists across blocks? (i.e., would the values reset at each block?)
[/quote]

could each block iterate through the items within the list of lists (by using nextvalue)?

This does not clear anything up -- the "items within the list of lists" are lists. It's not clear what you want to iterate through.
Please state clearly what exactly you want to do. Then I can answer your question.

hi,

i have a pretty complicated experiment that has many conditions and counterbalancing. is it possible to have a pointer for lists?
so for example if i have the below list and would like it to be called in block 1, could i have something like list.block1 = list.lr_2080?
<list lr_2080>
/ items = (2,1,1,2,2,1,2,1,1,2,2,1,2,1,1,2,2,1,2,2,1,1,2,1,1,2,2,1,2,1)
/ selectionmode = sequence
</list>

thank you!

You can have a list of lists, however, and select whatever list you want via a variable.

<list list_of_lists>
/ items = (list.a.nextvalue, list.b.nextvalue, list.c.nextvalue)
/ selectionmode = values.listnumber
</list>

with values.listnumber = 1 for list A,
values.listnumber = 2 for list B, and
values.listnumber = 3 for list C.

You simply always sample from list.list_of_lists per its nextvalue.

[code]<item myitems>
/ 1 = "A1"
/ 2 = "A2"
/ 3 = "A3"

/ 4 = "B1"
/ 5 = "B2"
/ 6 = "B3"

/ 7 = "C1"
/ 8 = "C2"
/ 9 = "C3"
</item>

<text mytext>
/ items = myitems
/ select = values.itemnumber
</text>

<list a>
/ items = (1,2,3)
/ selectionmode = sequence
</list>

<list b>
/ items = (4,5,6)
/ selectionmode = sequence
</list>

<list c>
/ items = (7,8,9)
/ selectionmode = sequence
</list>

<list list_of_lists>
/ items = (list.a.nextvalue, list.b.nextvalue, list.c.nextvalue)
/ selectionmode = values.listnumber
</list>

<values>
/ itemnumber = 0
/ listnumber = 0
</values>

<block example>
/ onblockbegin = [
values.listnumber = 2; // set to 1, 2 or 3 depending on the list you want to run
]

</block>

<trial mytrial>

values.itemnumber = list.list_of_lists.nextvalue;

Not sure what you mean. Please be more specific.
