Mechanisms of Averaging
We should emphasize in what way the averaging takes place. The dictates
of different landmarks, or different dimensions of experience, are averaged
, in a weighted fashion, to come up with a single intermediate criterion
as a basis for responding. The different dictates are not fighting'
directly over the control of the muscular outputs. This is what can generate
a single-peaked search distribution at an intermediate location, rather
than two different peaks, one appropriate for each dictate. The weights
dictate just which intermediate position becomes the target criterion.
