Associations between children’s attachment classification at 18 months andbehavior in a mother-child problem-solving task at 30 months were examined. The study partially replicated previous findings of Matas et al, and Frankel & Bates in terms of differences in maternal behaviors with children whose attachment classifications had differed 12 months earlier. Just as child behaviors did not show high leels of replication across the Matas et al and Frankel and Bates studies, so child behaviors in this study did not replicate either study exactly.
