How Tasks Change

Tom raises an interesting inquiry into the nature of how task properties change. I have thought about two ways in which task properties change: (1) through cognitive engineering efforts and (2) certain properties - cue intercorrelations and cue validities (note: two components of Re) - will change as more information is added. The first is self explanatory but the second deserves an example.

Consider again the Moneyball example we discussed at the meeting (which was fun by the way!). I have seven years worth of baseball statistics for each team. Simple analysis clearly shows that the validities and intercorrelations for all the cues (with the obvious exception of the wins-losses relationship) change from year to year.

The question I have is: how the heck do we model that, say, in the Continuum Standard Model I am proposing? It may be wisest to assume randomness and add a noise seed to those specified task properties. Feedback anyone? (Get it? It's a joke. You're right - not funny)
