Hi Dave, thanks for your reply.

I tried running the following code with three conditions, but when the first condition is met, it skips both the first and second conditions, and just keeps looping through trial_c instead.

/ skip = [
  if (script.currentblock == "block_1" && values.trial_a_criterion_learned) {
   return true;
  };
  if (script.currentblock == "block_2" && values.trial_b_criterion_learned) {
   return true;
  };
if (script.currentblock == "block_3" && values.trial_c_criterion_learned) {
 return true;
};
]

Any ideas?

Post runnable code.

Hi Dave,

Given the code below:
1. How can I make it so that when the response is "a" 3 or more times for both/either the a1 and a2 trials, both the a1 and a2 trials are skipped when that criterion is met. The same applies for the b1 and b2 trials. Despite the fact that the a2 trial's correct response is "b", and the b2 trial's correct response is "a"? So, essentially, regardless of the correct response for trials a1 and a2, the criterion should be based on the desired response, which is "a" for the a_trials, and "b" for the b_trials.

2. Is there a way to counterbalance for odd/even participant numbers using expt so that the desired responses are switched (e.g., for even numbered participants, the desired response for the a1 and a2 trials is now "b", and the desired response for the  b1 and b2 trials is now "a"?

Thanks!

You count things up in variables and skip on that basis. As simple as that.

As for counterbalancing, parameterize the correct responses, define two expt elements, set the correct responses to the applicable values /onexptbegin respectively.

Thanks! Would it be a case of using an IF statement to count if the desired key was pressed in each trial, or is there a more efficient way to achieve this?

For example, if the desired response is "z" (scan code 44):

/ ontrialend = [
    if (trial.a_trial.response == 44) {
        values.num_a_correct += 1;
    }
    else {
        values.num_a_correct += 0;
    }
]

Yes, as you can clearly see in the example code I gave you.

No, there isn't a more eficient way, and there is nothing inefficient about using conditional logic in the first place

Ok, sounds good. Thanks for all your help so far! :)

Thanks!

You count things up in variables and skip on that basis. As simple as that.

As for counterbalancing, parameterize the correct responses, define two expt elements, set the correct responses to the applicable values /onexptbegin respectively.

Thanks! Would it be a case of using an IF statement to count if the desired key was pressed in each trial, or is there a more efficient way to achieve this?

For example, if the desired response is "z" (scan code 44):

/ ontrialend = [
    if (trial.a_trial.response == 44) {
        values.num_a_correct += 1;
    }
    else {
        values.num_a_correct += 0;
    }
]

Hi Dave,

Given the code below:
1. How can I make it so that when the response is "a" 3 or more times for both/either the a1 and a2 trials, both the a1 and a2 trials are skipped when that criterion is met. The same applies for the b1 and b2 trials. Despite the fact that the a2 trial's correct response is "b", and the b2 trial's correct response is "a"? So, essentially, regardless of the correct response for trials a1 and a2, the criterion should be based on the desired response, which is "a" for the a_trials, and "b" for the b_trials.

2. Is there a way to counterbalance for odd/even participant numbers using expt so that the desired responses are switched (e.g., for even numbered participants, the desired response for the a1 and a2 trials is now "b", and the desired response for the  b1 and b2 trials is now "a"?
