Repeat Error Trials option in the Task Protocol does not work as expected.

The Repeat Error Trials option only works if the Task Program was created to be able to repeat error trials. Otherwise, selecting this option will have no effect.
An error trial is Task Program-specific. The Repeat Error Trial option will only work with those types of errors which the Task Program was created to recognize as an error trial.

will the repeat trial increase the total number of trials?

Hi Michael,

Yes they will increase your total trial count. When the trial is repeated later it will be a complete new trial saved in the data.

Thanks, but I follow the instruction. I set the Repeat_Trial_Flag=1 along with event code. The event is shown but the trial is not repeated. My code is following
DisplayFeedback/
error_state=TitileText(Group)

[error_state==0]/Repeat_Trial_Flag=1
event_code=ERRORFLAG

The display method is supposed to display correct or incorrect on the screen. It works before I set up Repeat flag, but now it only works for the correct case.
Thanks

Hi Michael,

In your protocol, have you checked the box for “use repeat trial flag”? When you are editing your protocol in Dex this option is on the “general” tab on the bottom left.
