title: Mutual Suppression: Comment on Paulhus et al. (2004).
abstract: Paulhus, Robins, Trzesniewski, and Tracy (Multivariate Behavioral Research, 2004 , 39, 305-328) suggested that the three types of two-predictor suppression situations-classical suppression, cooperative suppression, and net suppression--can all be considered special cases of mutual suppression, in that the magnitude of each of the two standardized partial regression coefficients exceeds the magnitude of its corresponding standardized bivariate regression coefficient. Classical suppression and cooperative suppression can be considered mutual suppression, but net suppression cannot. Hypothetical and empirical examples of net suppression in which the magnitude of the standardized partial regression coefficient for the suppressor variable is greater than, equal to, and less than the magnitude of its standardized bivariate regression coefficient are provided. The empirical examples were drawn from the social psychology literature relating psychological well-being outcomes to life aspirations.
