FR3 programming

Hi,

I have been using the FR3 notation in my programs for quite a while now thinking that wherever it was specified, the rat would only receive a reward if it pressed on the active lever 3 consecutive times. It turns out that this is not the case. The rat can press the active lever twice, go press the inactive lever a few times and then come back and press the active lever only once to then receive a reward.

Does anyone know how I can write the program so the rat has to perform 3 consecutive presses to get a reward? I have basically been using this:

s2,
3#R^tonelever--->s3

 

Thanks in advance for you help.

Hello,

You could try this:

S2,
#R^ToneLever: ADD R; IF R >= 3 [@FRMet, @Cont]
@FRMet: ---> S3
@Cont:  ---> S2
#R^InactiveLever: SET R = 0 ---> S2

Best Regards,
Gary
