Scaling task complexity along a single dimension.
Time-on-target on pursuit rotor tracking tasks has been shown to decrease for triangle, square, and circle templates, respectively. Since these templates are unrelated geometric shapes they cannot be scaled along a single continuous dimension. For the present study, templates were constructed to be continuously scaled by eccentricity. It was demonstrated that time-on-target on pursuit rotor tracking was a decreasing function of template eccentricity. Also, it was concluded that elliptical templates were preferred over the usual geometric templates because time-on-target relationships among templates can be examined.
