The reduced model of main factors is based on the removal from the larger model of main factors and interaction terms yielding P values of greater than 0.4. See text for details of this analysis.
Ant. anterior; Post., posterior; Ind, Individual.
Direction of the slope of correlation between the independent variable and dependent variable.
The interaction terms are listed in ascending order of P value and are coded in Tables 2,3,4,5,6as: a, buccal area peak displacement; b, ant. hyoid time of peak; c, buccal area time of peak; d, buccal area velocity; e, post. hyoid time of peak; f,ant. hyoid peak displacement; g, post. hyoid duration; h, post. hyoid displacement; I, post. hyoid time to peak; j, suspensorium duration; k, buccal area duration; l, gape peak displacement; m, suspensorium time to peak; n,gape time of peak; o, gape velocity; p, ant. hyoid time of peak; q,suspensorium velocity; r, ant. hyoid duration; s, gape time to peak; t, ant. hyoid velocity; u, suspensorium time of peak; v, gape duration; w, post. hyoid velocity.
