N=103. Unstandardized regression coefficients reported (B) with standardized coefficients (β) reported in the line below. Gender was controlled for the in the first step of all analyses. “Sobel” tests were used to examine the effect size of mutual suppression effects and significance (p<.05) is denoted from bootstrap bias corrected confidence intervals.
