People high in attachment‐related anxiety experience greater anxieties and ambivalence (e.g., M. Mikulincer, P. R. Shaver, N. Bar‐On, & T. Ein‐Dor, ) when feelings of relationship security are activated. The current research suggests that anxiously attached people also experience a decrease in implicit feelings of self‐worth. Across two studies participants high (vs. low) in attachment anxiety reported more negative implicit self‐evaluations after thinking about a time they felt loved and cared for by a close other. Study 2 further revealed that more negative implicit self‐evaluations are not a function of differences in the type of events recalled by high anxiety participants. These latter results suggest that security‐enhancing thoughts automatically activate a negative association with the self that is not consciously reflected in participants' written responses.
