[tips] Old but still useful?

[Dap Louw]

Tipsters

I'm looking for guidelines on when gathered data is regarded as too old to be 
used for an article in a scientific journal.  I specifically refer to 
Psychology.  I fully realize that it's relative and will be determined by 
several factors, but I would still appreciate your opinions.  Maybe a few 
examples could also help.

Thanks.
