The third study consisted of two experiments to determine whether subjects perceived the items of Gangestad and Snyder's Self‐Monitoring Scale as reflecting a unitary latent entity or separate, contradictory variables. It was concluded that the implicit theories approach appears to be a useful complement to traditional factor analytic studies, providing new ways of looking at a personality construct, clarifying some theoretical issues, and generating hypotheses for fu
