Macro in block Go to another block

Dear experts,

I’m trying to set up my experiment and I encounter some difficulties.

My experiment consists in 20 trials that I separated in 20 blocks (1 trial/block). I’m measuring reaction time.

If the subject success at the trial/block number 1 (RT>300ms) he access to the trial block number two, then if success to the number 2 he goes to the number 3 and so on until 20.

If the subject fail (RT<300ms) for example at the trial/block 10 then he has to go back to the trial 9, and if he fail again to the trial 9 he has to go to the trial 8 … and so on…:smiley:

I set up these parameters using a macro in the block like :

Expression “average in this block is less than 300 ms”
If true “Exit this block and present block X-1”
If false “Exit this block and present block X+1”

With X = the block where the subject actually is

The problem is if the subject fail to the trial/block 10, the software will shift to the trial/block 9, but if the subject fail AGAIN the software will continue with the trial 10 instead of shifting (as indicated by the MACRO) to trial block 8… :confused:

After three days trying and trying I’m desperate …
Does somebody have some solution ?
Thanks for your time and your help

I’m not 100% sure if this would help, but try adding the action called Clear “Trials Presented in This Block” Variable prior to the jump in all the macros.
