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

[Niels Taatgen]

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

What would a negative value of decay mean?  just curiosity, I don't think we are going to go that far :-)
