[ACT-R-users] what does negative decay mean?

[Cleotilde Gonzalez]

ACT-R friends,
   During explorations of the decay parameter in the ACT-R activation equation, we have wondered if any body has ever used a negative value or even zero, or even something different from the .5 default value.   What would a negative value of decay mean?  just curiosity, I don't think we are going to go that far :-)
