Lexical decision with yoked pair stimuli
#5
Thank you! So far it all seems to be working properly now which is very exciting!   My next (last?) question is how to program in a few breaks. Currently, my main lexical decision blocks (2 blocks for 2 participant groups) have 240 trials each, which is too many. I have created trial templates and a block in the procedures section for breaks, but I am not sure how to get these breaks into the block sequence. Is there a way to code it so that the block called "break" is automatically triggered every n number of trials in each of my lex_dec blocks, or to say that I want 3 breaks evenly spaced, something like that? Right now, my block sequence is defined as:

{"block_sequence": [                   
"practice",
  {"GroupA":["lexdec_blockA Wrote:
,
                      "GroupB":["lexdec_blockB"]}, 
                     "survey"
                    ]}

Thanks again for your patience and help! I am new to Finding Five and relatively new to coding.

Lucy - FF Researcher SupportHello! See my answers in-line in purple text. 

Thank you! After reading about the response_pairing option, I am still confused as to how to set this up. If I create two responses (WORD target and NOT WORD target), then how do I set which targets match each response? From what it sounds like, if I use the "partitioned" option, it would take the first 1/2 of my stimuli as WORD and the 2nd 1/2 as NOT WORD, is that correct?
Yes, correct. 
What do I do about stimuli that have no response (such as instructions etc.)?
These stimuli should be placed in a separate trial template, where you don't use response pairing. 
Does this mean that I have to have the stimuli uploaded in the proper order, or can I set this manually (ie list the stimuli names that should be the first choice response and then the second, etc.)?
See the documentation: https://help.findingfive.com/api/trial-t...html#basic response pairing goes off of the order of stimuli and responses in your trial template. 
Also, do I code the response_pairing option in the trial template for my targets, something like this:

"practice_primes": { 

  "type": "basic",

  "stimuli": ["pracP01", "pracP02", "pracP03", "pracP04", "pracP05","pracP06", "pracP07", "pracP08", "pracP09", "pracP10"],

  "order":["random"],
"order" is not a top-level property. If you are trying to randomize these stimuli, use a stimulus pattern: https://help.findingfive.com/api/trial-t...s-patterns

  "delay":[1.5]
Don't put 1.5 in brackets, as "delay" takes a numeric value, not a list. 
},



 

"practice_targets": {

  "type": "AFC",

  "stimuli": ["pracT01", "pracT02", "pracT03", "pracT04", "pracT05","pracT06", "pracT07", "pracT08", "pracT09", "pracT10"],

  "responses": ["word", "not word"],
  "response_pairing":["partitioned"],
Don't put "partitioned" in brackets, as "response_pairing" takes a string, not a list. 

Will it assume that pracT01-05 are WORD and 06-10 are NOT WORD?
Correct. 

Sorry for so many questions, and thank you for your help!

You're welcome!!
