Note. The path coefficients are unstandardized.

Contrast coding variables: C_{others positive/others negative} contrasts the combination of Congruent Positives and Incongruent Child Negative to the combination of Congruent Negatives and Incongruent Child Positives; C_CP/IN contrasts Congruent Positives with Incongruent Child Negative; C_CN/IP contrast Congruent Negatives to Incongruent Child Positives.
