RE: fixation cross location using yoked trials - aczyp - 10-25-2021
Hello Ting,
thank you very much for two solutions at once!
I went with number 2 (it said "overkill", after all) and the presentation now looks perfect. Thanks a lot!
RE: fixation cross location using yoked trials - aczyp - 07-21-2026
Dear FindingFive team, years later a new question has come up. It also concerns placement on the screen, so I am adding it to this thread so information stays together.
We are currently setting up a self-paced reading study, non-cumulative, chunks appear in the center of the screen. After some of the sentences, we want to collect binary grammaticality judgments as a control of sorts. These questions come up randomly.
Our code for this looks like this:
"exp_list1": {"trial_templates": ["list1a", "list1_questions"],
"pattern":{"order":"randomized_trials"}},
"list1a" and "list1_questions" are two trial templates, the second one has the questions.
The problem: Sentences without questions appear in the middle of the screen. Sentences with questions appear at a higher position, so participants will realize right away that this sentence merits attention. We want to make sure all sentences appear in the same position.
From our old experiment that had the same issue (see this thread), you proposed combining stimuli and questions in the procedures blocks, rather than within the trial templates. Like this:
"exp_list1": {"trial_templates": ["fixation_cross_miniblock", "list1", "response_miniblock"],
"pattern":{"order":"alternate", "repeat":1}}
This worked because in the old experiment, all items were followed by a question.
For our new experiment, I am wondering how I can combine the two things. If I don't want sentences with questions to move up, I suppose I need to put the response into its own trial template and use it in a block. But I also need to define a block that allows me to randomly switch between sentences with and without questions.
Can you give me some guidance for how this would work? Can I define a block inside another block, or isn't it _that_ recursive? Any suggestion is highly welcome. Thanks a lot in advance!
