Oh, my result from today:
I scored myself 2 out of 4.

* traffic light -> failed. I stopped at a traffic light, looked on my watch and then remembered I should have done an RC.
* hear music -> not sure, I don't always notice music when it's there...
* throw something in the garbage -> YES this triggered even a kind of conditioned response. I threw something away and was instantly reminded of the task.
* hear laughter -> YES
