+x+x+x+x+x+x+x+xHi Dave, Basically, if participants press the correct key to criterion (60% accuracy) at the end of one block, I want to start a different block where the first stimulus that has been learned to criterion is no longer there, but the stimuli remain, until they are also learned to criterion. The issues I can't seem to resolve, and am hoping you can help with, are as follows: 1. The percentage of time that a participant presses the correct key for each stimulus is not displayed correctly on the feedback screen. It should get the value from the percentCorrect property, but that doesn't seem to be working. 2. How can I make it so that when one stimulus has been learned to criterion, the others remain until they are all learned? 3. Is there a better way to achieve what I'm trying to do? For example, is there a criterion function in Inquisit? Below is the code that I have been working with. <values> / num_a_correct = 0; / num_b_correct = 0; </values>
<expt> / blocks = [1=block.start_block] </expt>
<block start_block> / trials=[1-5=noreplace(trial.a_trial, trial.b_trial)] / branch=[if (trial.a_trial.percentCorrect >= 60) block.branch_block_a] / branch=[if (trial.b_trial.percentCorrect >= 60) block.branch_block_b] </block>

Hi Dave, If one stimulus has been learned, say Stimulus A, I'd like to bring in another stimulus, say Stimulus C (i.e., trial.c_trial). Is there a wa to achieve this without disrupting the flow of the program? Thanks! The same approach I already showed you applies. /skip the c trial as long as either the a and b trials have not been learned. Don't skip it as soon as either has been learned. Ok, that makes sense, thanks! :) Hi Dave, I have another question. How would I make it so that there are separate blocks for each phase of learning? For example, if a participant learns Stimulus A to criterion in Block 1, then there will be a break, after which they will start Block 2 where they would only be presented with Stimulus B and C, until one of them is learned to criterion, etc. I'm not sure how this can be done using the / skip attribute approach. Or should a different approach be used to achieve this? Thanks! Why would that require separate blocks? But regardless, the /skip approach is just as applicable as it was before. Ok, will give that a go. Thanks again! 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"? <values> / num_a_trials_response_a = 0; / num_a1_correct = 0; / num_a2_correct = 0;

Hi Dave, If one stimulus has been learned, say Stimulus A, I'd like to bring in another stimulus, say Stimulus C (i.e., trial.c_trial). Is there a wa to achieve this without disrupting the flow of the program? Thanks! The same approach I already showed you applies. /skip the c trial as long as either the a and b trials have not been learned. Don't skip it as soon as either has been learned. Ok, that makes sense, thanks! :) Hi Dave, I have another question. How would I make it so that there are separate blocks for each phase of learning? For example, if a participant learns Stimulus A to criterion in Block 1, then there will be a break, after which they will start Block 2 where they would only be presented with Stimulus B and C, until one of them is learned to criterion, etc. I'm not sure how this can be done using the / skip attribute approach. Or should a different approach be used to achieve this? Thanks! Why would that require separate blocks? But regardless, the /skip approach is just as applicable as it was before.

+x+x+x+x+xHi Dave, Basically, if participants press the correct key to criterion (60% accuracy) at the end of one block, I want to start a different block where the first stimulus that has been learned to criterion is no longer there, but the stimuli remain, until they are also learned to criterion.

Hi Dave, If one stimulus has been learned, say Stimulus A, I'd like to bring in another stimulus, say Stimulus C (i.e., trial.c_trial). Is there a wa to achieve this without disrupting the flow of the program? Thanks! The same approach I already showed you applies. /skip the c trial as long as either the a and b trials have not been learned. Don't skip it as soon as either has been learned.

+x+xHi Dave, Basically, if participants press the correct key to criterion (60% accuracy) at the end of one block, I want to start a different block where the first stimulus that has been learned to criterion is no longer there, but the stimuli remain, until they are also learned to criterion.

Hi Dave, Thanks for the help, much appreciated. There seems to be an issue that when Stimulus B is learned to criterion, but not A, it goes to the Stimulus A branch block, not B. Is there something wrong with the logic of the code here or is it something else: <block start_block> / trials=[1-10=noreplace(trial.a_trial, trial.b_trial)] / branch=[if (trial.a_trial.correctCount >= 5) block.branch_block_a] / branch=[if (trial.b_trial.correctCount >= 5) block.branch_block_b] </block> Thanks! Hi Dave, Please ignore my previous reply, I managed to figure it out. Thanks again!

Hi Dave, Thanks for the help, much appreciated. There seems to be an issue that when Stimulus B is learned to criterion, but not A, it goes to the Stimulus A branch block, not B. Is there something wrong with the logic of the code here or is it something else: <block start_block> / trials=[1-10=noreplace(trial.a_trial, trial.b_trial)] / branch=[if (trial.a_trial.correctCount >= 5) block.branch_block_a] / branch=[if (trial.b_trial.correctCount >= 5) block.branch_block_b] </block> Thanks!

+xHi Dave, Basically, if participants press the correct key to criterion (60% accuracy) at the end of one block, I want to start a different block where the first stimulus that has been learned to criterion is no longer there, but the stimuli remain, until they are also learned to criterion. The issues I can't seem to resolve, and am hoping you can help with, are as follows: 1. The percentage of time that a participant presses the correct key for each stimulus is not displayed correctly on the feedback screen. It should get the value from the percentCorrect property, but that doesn't seem to be working. 2. How can I make it so that when one stimulus has been learned to criterion, the others remain until they are all learned? 3. Is there a better way to achieve what I'm trying to do? For example, is there a criterion function in Inquisit? Below is the code that I have been working with. <values> / num_a_correct = 0; / num_b_correct = 0; </values>
