periperiperika555 - 9/30/2023

Hello,

I hope this message finds you well. We are currently working on a research project at our university involving "Cyberball 5," and we are looking to create three Cyberball tasks for this study.

To use fMRI in our research, we need to transition from mouse-click-based controls to keyboard controls entirely. However, we have encountered an issue when setting "validresponse=("4","9")" and "inputdevice=keyboard" in the "trial" section. It seems that when Player 2 throws the ball, it goes in the opposite direction and does not function correctly. (We want to configure it so that pressing the 4 key throws to Player 1, and pressing the 9 key throws to Player 3.)

By the way, when we set the key for throwing to Player 3 as "validresponse=("E","I")," the ball is thrown correctly only to Player 3, and it works as expected. Any key other than "I" does not work correctly.

Currently, the program looks like this:

<trial npctrial>
/ ontrialbegin = [
    values.received_from = values.ball_at;
    values.ball_at = values.throw_to;
    if (values.ball_at == 2) {
        values.player2received += 1;
    };
    expressions.set_offsets;
    
    values.player1state = (values.ball_at == 1) + 1;

We are running out of time and are in quite a predicament. Any help you can provide would be greatly appreciated. Thank you in advance.

Your /branch logic in <trial player2> is wrong and broken.

FIrst, == is the wrong operator; it's a comparison operator, not the assignment operator. If you want to set values.throw_to based on the player's response, you need =.
https://www.millisecond.com/support/docs/current/html/language/expressions/operators.htm

Second, you're missing the statement separator after setting values.throw_to.
https://www.millisecond.com/support/docs/current/html/language/expressions/operators.htm

Expressed correctly, those branches ought to read

Dear Dave,

Thank you so much for your guidance. Following your advice, I was able to rewrite it, and now it's working perfectly! It looks like my experiment is on track to succeed. I genuinely appreciate your help.

Hello, Dave.

May I ask another question?
We are looking to program a Cyberball game with 30 throws in 4 sets, automatically repeating. However, currently, after one set, it goes to "trial.end," and we can't seem to run the 4 sets consecutively.
We would like to have it in a pattern like

"Cyberball game -> 10-second break -> Cyberball game -> 10-second break...".

If we can achieve this, our experiment will be complete. Could you please assist us with this?

You need to set values.stop back to false and values.throwcount back to 0 between sets, e,g, /onblockbegin in <block generateschedule>,

Hello Dave,

I hope you're well. I wanted to thank you for your advice yesterday. I tried implementing your suggestions, but now the game seems to go on forever and doesn't stop after one set. I've included the changes I made below. Could you please let me know if I've made the corrections correctly? I apologize for the multiple inquiries, and thank you for your assistance.

Hello Dave,

I hope you're well. I wanted to thank you for your advice yesterday. I tried implementing your suggestions, but now the game seems to go on forever and doesn't stop after one set. I've included the changes I made below. Could you please let me know if I've made the corrections correctly? I apologize for the multiple inquiries, and thank you for your assistance.

Nowhere in that code do you include where you set values.stop back to false and values.throwcount back to 0, which are the relevant changes.

I appreciate your help and apologize again for any inconvenience.

Nowhere in that code do you include where you set values.stop back to false and values.throwcount back to 0, which are the relevant changes.

The big mistake in the code you posted is that you do not ever increase the throwcount anymore, so the block has no way of knowing when to stop. You really need to fix that.

Dear Dave,

Thank you for your prompt response! It seems I had misunderstood, and after understanding and making the necessary corrections, the program now works perfectly as intended. I sincerely appreciate you guiding me with the correct code. Thanks to you, we have successfully completed the program we wanted to create. I cannot express my gratitude enough. Thank you very much.

Best regards,
Saito
