## Abstract

One method to test whether graphical ratings are linear response measures is to prescribe

an integration rule and test whether the resulting pattern of factorial curvesis that predicted by this rule.

This method does not guarantee that respondents do

not use an integration rule different from the prescribed rule. To resolve this problem,

we had participants graphically rate either the weight of a beam varying in density

and volume or the velocity of balls of different masses rolling down slants of

various lengths. After the experiment, we asked participants whether they knew the

formulas to calculate beam mass and ball velocity. The participants who knew the

correct formulas produced patterns of factorial curves in agreement with the formulas.

These results confirm that graphical ratings are linear response measures.
