Numeric Comparison Model

powerful...

For example, it seems to me that the following comparisons would take
significantly different amounts of time to make:

1 < 2
1233393 < 1232393

    ACT-R 5.0 will allow those operations within productions automatically.
In a manner similar to the negation test one can now use <, <=, >, or >= as
slot test modifiers when the values are numbers.  The sperling model in unit
3 uses them if you want to see an example of their use.
