The relation between aspects of pregnant women's fantasy representations on the Rorschach test and infant attachment status at 1 year was studied. The Manual for Assessing Primary Process Manifestations in Rorschach Responses (Holt, 1968) was used to score Rorschach protocols gathered from 25 women during their first pregnancies. Twelve-month-olds and their mothers were later videotaped in the Strange Situation, a laboratory procedure that assesses infant attachment behaviors. The findings support the hypothesis that primary process integration during pregnancy is significantly and positively related to infant security of attachment at 1 year. Also, the extent to which mothers referred specifically to pregnancy, birth, and mothering in their Rorschach responses was linked to later infant security of attachment. The results suggest a relation between empathic maternal behaviors and dimensions of mothers' unconscious mental representations measurable prior to the infant's birth.
