Table 3.

Loadings of processing parameters on the first two principal components (PC1 and PC2)

Parameter	PC1	PC2
(18) Duration hyobranchial movement cycle	0.836^a	−0.123
(15) Magnitude hyobranchial depression	0.779^a	0.353
(14) Magnitude hyobranchial elevation	0.663^a	0.480
(1) Magnitude gape opening	−0.036	0.872^a
(3) Duration gape opening	0.300	0.699^a
Total variance explained (%)	48.1	21.0

Parameters marked with ^aload strongly (> 0.5) on each respective principal component. Note that parameters connected to hyobranchial movement load more strongly in PC1 while parameters connected to gape movements load more strongly on PC2
