Age Age2 Sex Age × Sex
ANGER Chi = 16.23, P = 5.61 10−5 Chi = 0.03 P = 0.84 Chi = 3.21 P = 0.07 Chi = 0.04 P = 0.83
HAPPINESS Chi = 4.88 P = 0.0271 Chi = 2.62 P = 0.10 Chi = 0.0.01 P = 0.91 Chi = 0.0027 P = 0.95
FEAR Chi = 45.41 P = 0.16 10−11 Chi = 0.127 P = 0.72 Chi = 1.12 P = 0.28 Chi = 3.04 P = 0.08
SADNESS Chi = 3.36 P = 0.066 P = 4.08 P = 0.043 Chi = 0.91 P = 0.34 Chi = 0.38 P = 0.56

The linear and quadratic effects of age, the effect of sex and interaction between age and sex effects are evaluated by comparing the fit of the logistic model with and without these factors38.
