fixation cross location using yoked trials

[Ting]

Hi!

Is it possible that somehow the trial template and the block definitions are mixed together? The code you listed is the definition of the block, which will expect two templates to "yoke" together. So, instead of putting "fixation_cross" in there, which I assume is the name of a stimulus, you'll need to create a new "fixation_cross_template" and use that instead. Something like:

Code:

"target_prime_lexical_decision_block": {
    "trial_templates": ["fixation_cross_template", "targets_template"],
    "pattern": {"order": "alternate_random", "repeat": 1}
}

The "fixation_cross_template" will then have the "fixation_cross" as the only stimulus in its stimulus list, like:

Code:

"fixation_cross_template" {
    ...,
    "stimuli": ["fixation_cross"],
    ...
}

Let me know if I got it right. Happy to follow up!
