Table 3.

The influence of each shape property on shape-taste matches as shown by binary logistic regression GEE.

Shape properties	UK	Colombia
Roundness/angularity	Angular = sour**	Angular = sour***
Symmetry/asymmetry	Symmetrical = sweet***	Symmetrical = sweet**
Number of elements	Fewer elements = sweet***	Fewer elements = sweet***
Roundness/angularity × symmetry	No effect	No effect
Roundness/angularity × number of elements	Rounder × fewer elements = sweet**	Rounder × fewer elements = sweet***
Symmetry/asymmetry × number of elements	Symmetrical × fewer elements = sweet**	No effect
Roundness/angularity × symmetry/asymmetry × number of elements	Rounder × symmetrical × fewer elements = sweet*	No effect

Note that all effects that are significant include both polar properties (e.g., symmetry and asymmetry, or roundness and angularity).
