Matching up delay and immediate blocks?

sandy_d — Thu, 17 Nov 2016 18:00:29 GMT

Hello,

I'm trying to run a series of sequences within a delay block in the DDT Food and Money so that the left hand and right hand choice will have the same starting value at the right hand side at the beginning of each block time. (ie: so the left hand side will display " 4 servings of grapes right now" and the right hand side will display "4 servings of grapes in 30 minutes").

My question is, how do I do it so that at the start of each of the delay blocks, the starting value of food is the same for the immediate (left) and for the delayed (right hand side).
Of the 3 possible food blocks I have, this is working correctly for the first two (which goes through the block of 4 servings of food followed with 7 time delays) .

My code so far is:

<data>
/ columns = (build, computer.platform, date,time,subject, group,
    values.blockcount,blocknum,blockcode,values.blocktype,values.order,
    values.trialcount,trialnum,trialcode,response,latency,
    values.delay,parameters.delayedreward_4, parameters.delayedreward_8, parameters.delayedreward_12,values.immediatereward,
    values.delayedresponsestreak,values.immediateresponsestreak,
    values.ip_desc,values.ip_asc,values.ip)
/ separatefiles = true
</data>

The code is incomplete and broken as a consequence. There are various references to <parameters> throughout it, yet no <parameters> element is present. This makes it impossible to answer your question adequately.

You can attach files to a post via +Insert -> Add file. It is generally not necessary to paste entire scripts encompassing hundreds or thousands of lines of code into a message's body. Apart from being error-prone, it makes posts hard to read and the code hard to work with. If you have questions about particular parts of the code, it is better to include only those parts in the message body to direct the reader's focus to what's important. Thanks.

Would the attached file provide more clarification?

[/quote]

Not really. Recall what I tried to explain in previous threads, such as https://www.millisecond.com/forums/Topic20125.aspx#bm20147

On that basis, you need to clarify the following: Do you want

Delay 1
food4_desc -> food4_asc
Delay 2
food4_desc -> food4_asc
Delay 3
food4_desc -> food4_asc
...
Delay 1
food8_desc -> food8_asc
Delay 2
food8_desc -> food8_asc
Delay 3
food8_desc -> food8_asc
...
Delay 1
food12_desc -> food12_asc
Delay 2
food12_desc -> food12_asc
Delay 3
food12_desc -> food12_asc
...

i.e., run through all the delay levels for 4 servings, then through all delay levels for 8 servings, then through all delay levels for 12 servings

OR

do you want

Delay 1
food4_desc -> food4_asc
food8_desc -> food8_asc
food12_desc -> food12_asc
Delay 2
food4_desc -> food4_asc
food8_desc -> food8_asc
food12_desc -> food12_asc
....

i.e., complete delay level 1 (30 minutes) for 4 servings, followed by delay level 1 for 8 servings, followed by delay level 1 for 12 servings
and then
delay level 2 for 4 servings, followed by delay level 2 for 8 servings, delay level 2 for 12 servings,
and so forth.

This difference is important.

[/quote]

I'm trying to have it so that all the delays for the 4 servings run, then all the delays for the 8 servings, then all the delays for the 12 servings.

[/quote]

Okay, then this is wrong:

/ blocks = [1=foodchoice; 2-7=sequence(food4_desc, food4_asc, food8_desc, food8_asc, food12_desc, food12_asc)]

You have 7 delay levels. If you want to run through them grouped by number of servings, you need to run
- 7 times the sequence(food4_desc, food4_asc), followed by
- 7 times the sequence(food8_desc, food8_asc), followed by
- 7 times the sequence(food12_desc, food12_asc)

i.e.,

/ blocks = [1=foodchoice;
    2-8=sequence(food4_desc, food4_asc);
    9-15=sequence(food8_desc, food8_asc);
    16-22=sequence(food12_desc, food12_asc)]

As also noted previously, you then also need to sample a new delay-level from <list delays> after *each chunk of TWO blocks*, not after each chunk of FOUR blocks as your script (still) does currently:

/ onblockbegin = [
    if (mod(values.blockcount,4)==1)
        values.delay=list.delays.nextvalue
]

needs to read

/ onblockbegin = [
    if (mod(values.blockcount,2)==1)
        values.delay=list.delays.nextvalue
]
