repeat a trial in case of no-response

saviano — Mon, 22 Jul 2024 18:00:46 GMT

Hi,
I'm completely new in Inquisit. I'm trying to create an experiment on pleasantness judgments: the participant will see on the screen a photo and through two buttons he will be able to choose whether he likes it or not. There are four trials total, and I wish, in case of no-response, for a text to appear on the screen and for the trial to be repeated, but I have some issues. Can somebody help me?
Thanks.

/ stimulustimes = [0 = clearScreen, fixation]
/ branch = [
    if (values.condition == 1){
        return trial.congruent;
}
]
/ trialduration = 1000
</trial>

<trial congruent>
/ stimulustimes = [0 = practicefaces, likeds, dislikesx]

    if (trial.congruent_practice.error){
        return trial.repeat;
    } else {

    }
]
</trial>

Provide complete, runnable code, not isolated snippets, please. They are not useful and most of what's relevant is missing.

Very sorry,
I'll send the complete code so far. There are two blocks and the function to repeat the trial is implemented only in the trial.congruent_practice (I wanted to solve the problem first and then implement it in the second one too).
Better now?

In the future, please:
(1) Do not paste entire scripts into a post's body. This is error-prone and difficult to work with.
(2) If your code requires external files (images, etc.) to run, always provide those along with the code.

Put everything needed in a ZIP archive, then use +Insert -> Add File... to attach the ZIP containing the script and other files to a post.
