This table illustrates how the precision of each navigation component impacts cumulative route improvements, which are quantified by a positive intergenerational increase in path efficiency in the “experimental” condition (“pair” and “solo” are control conditions).

The “normal precision” column reflects scores from the current model parameters. The “high precision” and “low precision” reflect halving and doubling the standard deviation, which is then transformed back into precision parameter κ for a navigational component Von Mises distribution.
