Josh,
Gigerenzer doesn't sound like old stuff or irrelevant to me , with my
limited knowledge, (and also seems like a pretty good example of how v.
much more practical it can be to think imaginatively than mathematically,
no?)::
"how do real people make good decisions under the usual conditions of little
time and scarce information? Consider how players catch a ball-in baseball,
cricket, or soccer. It may seem that they would have to solve complex
differential equations in their heads to predict the trajectory of the ball.
In fact, players use a simple heuristic. When a ball comes in high, the
player fixates the ball and starts running. The heuristic is to adjust the
running speed so that the angle of gaze remains constant -that is, the angle
between the eye and the ball. The player can ignore all the information
necessary to compute the trajectory, such as the ball's initial velocity,
distance, and angle, and just focus on one piece of information, the angle
of gaze."

Josh:This is all pretty old stuff for mainstream AI -- see Herb Simon and
bounded
rationality. What needs work is the cross-modal interaction, and
understanding the details of how the heuristics arise in the first place
from
the pressures of real-time processing constraints and deliberative
modelling.

Josh/Bob:
What do Gigerenzer's fast and frugal heuristics have to say about this?
