Problem in displaying Accuracy

Pallavi

Hello everyone,

I am facing some difficulty in giving feedback to the participants. Whenever i am using rest_feedback in the block sequence, it is showing correct feedback after trial but in log file the accuracy is in decimal numbers (rather than100% or 0). But when i tried reset_feedback in the trial, accuracy was shown as 0 and 100 in the log file but the feedback were not correct after trial. Is there any way so that in log file accuracy could be feeded as 0 and 100 and feedback to the participants could be correct.

My second problem is that i want my target sketchpad to be displayed for 1 minute but if the participant gives the response then next target should be displayed. How can i run this?

Also i have question regarding running more trials. I am designing a 2 back task. I want to know how to run multiple trials with different list everytime.

It would be really helpful if anybody could help me out with this.

Thanks.

Hi @Pallavi ,

I think you're confusing the correct and acc variables.

• correct always refers to the correctness of the last response, and is either 1 (correct) or 0 (incorrect).
• acc refers to the running accuracy since the last time that the feedback variable were reset, and is a percentage.D

Does that clear things up? See also:

Also i have question regarding running more trials. I am designing a 2 back task. I want to know how to run multiple trials with different list everytime.

Perhaps you can start a new question for this. If you do, make sure to provide a lot more details about exactly you want to do!
