Attachment to the mother at 1 year of age was studied in 46 "high-risk" offspring of index mothers with a history of nonorganic psychosis and in 80 demographically similar control offspring. Attachment was measured in the home in a standardized manner by a modified version of Ainsworth's Strange Situation procedure. Three different patterns, representing(More)
This article describes the development of a prospective, longitudinal study of 88 "high-risk" offspring of pregnant index women with a history of nonorganic psychoses and 104 offspring of demographically-similar pregnant control women. The maternal psychoses represented the diagnostic categories, Schizophrenia, Cycloid Psychosis, Affective Illness,(More)
Exploratory behavior and deviations on three dimensions--fear of strangers, attachment to mother, and exploration--were studied in 46 infants of mothers with a history of psychosis and 80 control infants. While high-risk infants did not differ from controls on exploration alone, they showed multiple deviations on the three dimensions more frequently than(More)
Mother-infant interaction during feeding and in an unstructured play situation was studied in the home at 1 year of age in 46 index mother-infant pairs in which the mother had a history of nonorganic psychosis and in 80 demographically similar control pairs. As was true at the five previous observation ages, some aspects of the interaction were(More)
Mother-infant interaction during feeding and in an unstructured play situation was studied in the home at 3.5 and 6 months of age in index mother-infant pairs in which the mother had a history of nonorganic psychosis (n = 48 and 52 at 3.5 and 6 months, respectively) and in demographically similar control pairs (n = 80 and 79). Interaction was significantly(More)
Mother-infant interaction during a feeding was studied at about 3 days of age in 51 index mother-infant pairs in which the mother had a history of nonorganic psychosis and in 73 demographically similar control pairs. Interaction was significantly more negative and deviant in index than control cases, index mothers establishing a significantly more negative(More)
Mother-infant interaction during feeding and in an unstructured play situation was studied in the home at 3 weeks and 6 weeks of age in index mother-infant pairs in which the mother had a history of nonorganic psychosis (n = 42 and 51 at 3 and 6 weeks, respectively) and in demographically similar control pairs (n = 60 and 78). At both ages, interaction was(More)
Fear of strangers ( FOS ) during the infant's first year was studied in 46 "high-risk" offspring of index mothers with a history of nonorganic psychosis and in 80 demographically similar control offspring. FOS was measured in the home by a standardized test at 1 year of age and by repeated interviews with the mother during the first year. As compared with(More)
