Negative decay would be.... Incubation? Consolidation? It would mean the activation would increase instead of decrease.
More realistically, I and others have experimented with values in the 0.2-0.3 range when dealing with models of multiday experiments. Jon Fincham and John Anderson wrote a paper about it: http://act-r.psy.cmu.edu/publications/pubinfo.php?id=133

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 :-)
