Hello

As much as I am happy to say we're launching the real experiment soon, there is an outstanding issue with one of the tasks, which has been requiring me to re-run the task (it takes 20 mins) multiple times, and I have tried all strategies listed. To my amazement, the issue is persisting. I have 38 Positive trials, 6 Negative trials, and 6 Catch trials, 50 T. I have used noreplace, I've tried noreplacenorepeat, i've tried resetintervals, manually typing in trials for block given they differ in number. Yet, when I run the exp, and look at my data, whilst the 38 positive trials are fine, the catch and negative trials are misbehaving! Sometimes there are 8 catch trials instead of 6 (and thus 4 negative), or 7 negatives (and 5 catch). Any ideas as to why this is so?
Thank you kindly

That's running 51 trials, not 50.

Doing so produced (counting the output) 36 positive trials instead of 38, but this time produced 6 catch trials and 6 negative trials, but this means it has sacrificed two positives?

produced 37 positive trials not 36, my bad, but this is still one short no?

I don't know what you're doing.

produces 38 countdownP trials, 6 countdownN trials and 6 countdownC trials exactly as it should.

> am I right in thinking it is because of the trial break/pause. I implement this when it reaches halfway, to branch into a break trial. Thus, I can simply add an extra positive item/trial to make up the number. This is the only thing I can think of, yet when I applied code to create a break, from the forum, it was said that it would leave the rest of the trials alone/unaffected, but in this case it has taken one away

It's not taking anything away. You /branch to the break trial from one of the countdown trials. All the countdown trials are run, you can easily verify this for yourself.

The respective countdown trial obviously cannot and will not then go on to the respective scenario trial. The countdown trial is over and things have moved on to the break trial.

Okay then I'm honestly not sure why it cuts one short, I mean, I attach the recent output file based on the above. I guess I can add one extra, I have kept going over the numbers carefully, making sure I have not miscounted, and I haven't so is very difficult to know why this happens!

But thank you though anyway as always I much appreciate all this help

The output file is useless without the exact code that produced it.

Hello

As much as I am happy to say we're launching the real experiment soon, there is an outstanding issue with one of the tasks, which has been requiring me to re-run the task (it takes 20 mins) multiple times, and I have tried all strategies listed. To my amazement, the issue is persisting. I have 38 Positive trials, 6 Negative trials, and 6 Catch trials, 50 T. I have used noreplace, I've tried noreplacenorepeat, i've tried resetintervals, manually typing in trials for block given they differ in number. Yet, when I run the exp, and look at my data, whilst the 38 positive trials are fine, the catch and negative trials are misbehaving! Sometimes there are 8 catch trials instead of 6 (and thus 4 negative), or 7 negatives (and 5 catch). Any ideas as to why this is so?
Thank you kindly

That's running 51 trials, not 50.

Doing so produced (counting the output) 36 positive trials instead of 38, but this time produced 6 catch trials and 6 negative trials, but this means it has sacrificed two positives?

produced 37 positive trials not 36, my bad, but this is still one short no?

I don't know what you're doing.

produces 38 countdownP trials, 6 countdownN trials and 6 countdownC trials exactly as it should.

> am I right in thinking it is because of the trial break/pause. I implement this when it reaches halfway, to branch into a break trial. Thus, I can simply add an extra positive item/trial to make up the number. This is the only thing I can think of, yet when I applied code to create a break, from the forum, it was said that it would leave the rest of the trials alone/unaffected, but in this case it has taken one away

It's not taking anything away. You /branch to the break trial from one of the countdown trials. All the countdown trials are run, you can easily verify this for yourself.

The respective countdown trial obviously cannot and will not then go on to the respective scenario trial. The countdown trial is over and things have moved on to the break trial.

Okay then I'm honestly not sure why it cuts one short, I mean, I attach the recent output file based on the above. I guess I can add one extra, I have kept going over the numbers carefully, making sure I have not miscounted, and I haven't so is very difficult to know why this happens!

But thank you though anyway as always I much appreciate all this help

The output file is useless without the exact code that produced it.

Hello

As much as I am happy to say we're launching the real experiment soon, there is an outstanding issue with one of the tasks, which has been requiring me to re-run the task (it takes 20 mins) multiple times, and I have tried all strategies listed. To my amazement, the issue is persisting. I have 38 Positive trials, 6 Negative trials, and 6 Catch trials, 50 T. I have used noreplace, I've tried noreplacenorepeat, i've tried resetintervals, manually typing in trials for block given they differ in number. Yet, when I run the exp, and look at my data, whilst the 38 positive trials are fine, the catch and negative trials are misbehaving! Sometimes there are 8 catch trials instead of 6 (and thus 4 negative), or 7 negatives (and 5 catch). Any ideas as to why this is so?
Thank you kindly

That's running 51 trials, not 50.

Doing so produced (counting the output) 36 positive trials instead of 38, but this time produced 6 catch trials and 6 negative trials, but this means it has sacrificed two positives?

produced 37 positive trials not 36, my bad, but this is still one short no?

I don't know what you're doing.

produces 38 countdownP trials, 6 countdownN trials and 6 countdownC trials exactly as it should.

> am I right in thinking it is because of the trial break/pause. I implement this when it reaches halfway, to branch into a break trial. Thus, I can simply add an extra positive item/trial to make up the number. This is the only thing I can think of, yet when I applied code to create a break, from the forum, it was said that it would leave the rest of the trials alone/unaffected, but in this case it has taken one away

It's not taking anything away. You /branch to the break trial from one of the countdown trials. All the countdown trials are run, you can easily verify this for yourself.

The respective countdown trial obviously cannot and will not then go on to the respective scenario trial. The countdown trial is over and things have moved on to the break trial.

Okay then I'm honestly not sure why it cuts one short, I mean, I attach the recent output file based on the above. I guess I can add one extra, I have kept going over the numbers carefully, making sure I have not miscounted, and I haven't so is very difficult to know why this happens!

But thank you though anyway as always I much appreciate all this help

The output file is useless without the exact code that produced it.

Ah, I attached the exact script here that was used to generate the output,

Hello

As much as I am happy to say we're launching the real experiment soon, there is an outstanding issue with one of the tasks, which has been requiring me to re-run the task (it takes 20 mins) multiple times, and I have tried all strategies listed. To my amazement, the issue is persisting. I have 38 Positive trials, 6 Negative trials, and 6 Catch trials, 50 T. I have used noreplace, I've tried noreplacenorepeat, i've tried resetintervals, manually typing in trials for block given they differ in number. Yet, when I run the exp, and look at my data, whilst the 38 positive trials are fine, the catch and negative trials are misbehaving! Sometimes there are 8 catch trials instead of 6 (and thus 4 negative), or 7 negatives (and 5 catch). Any ideas as to why this is so?
Thank you kindly

That's running 51 trials, not 50.

Doing so produced (counting the output) 36 positive trials instead of 38, but this time produced 6 catch trials and 6 negative trials, but this means it has sacrificed two positives?

produced 37 positive trials not 36, my bad, but this is still one short no?

I don't know what you're doing.

produces 38 countdownP trials, 6 countdownN trials and 6 countdownC trials exactly as it should.

> am I right in thinking it is because of the trial break/pause. I implement this when it reaches halfway, to branch into a break trial. Thus, I can simply add an extra positive item/trial to make up the number. This is the only thing I can think of, yet when I applied code to create a break, from the forum, it was said that it would leave the rest of the trials alone/unaffected, but in this case it has taken one away

It's not taking anything away. You /branch to the break trial from one of the countdown trials. All the countdown trials are run, you can easily verify this for yourself.

The respective countdown trial obviously cannot and will not then go on to the respective scenario trial. The countdown trial is over and things have moved on to the break trial.

Okay then I'm honestly not sure why it cuts one short, I mean, I attach the recent output file based on the above. I guess I can add one extra, I have kept going over the numbers carefully, making sure I have not miscounted, and I haven't so is very difficult to know why this happens!

But thank you though anyway as always I much appreciate all this help

The output file is useless without the exact code that produced it.

Ah, I attached the exact script here that was used to generate the output,

This is your mistake and this is what you need to rethink and fix:

https://www.millisecond.com/forums/FindPost31308.aspx

You need to think about when you are doing stuff (such as branching to the break trial) and what the consequences are.

The branch to the break trial does not belong in the countdown trials. It belongs in the comprehension feedback trials.

countdown trial 1-24:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback

countdown trial 25:
countdown --branch-to--> break //Consequence: No corresponding scenario, comprehension and feedback trial

countdown trial 26-50:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback

countdown trial 1-24:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback

countdown trial 25:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback --branch-to--> break

countdown trial 26-50:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback

Dave - 4/12/2021

Just to elaborate, the flow you had implemented is this:

countdown trial 1-24:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback

countdown trial 25:
countdown --branch-to--> break //Consequence: No corresponding scenario, comprehension and feedback trial

countdown trial 26-50:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback

A flow that avoids the problem would be:

countdown trial 1-24:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback

countdown trial 25:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback --branch-to--> break

countdown trial 26-50:
countdown --branch-to--> scenario --branch-to--> comprehension --branch-to--> feedback
