The adult adjustment of children who were partially reared in foundling homes or other child care institutions is largely unknown. There is ample proof that major personality and character disturbances attributed to lack of maternal or emotional nurture appear in many children during or soon after periods of institutional care. Several authoritative reviews of the subject have appeared (Bowlby, 1952; Yarrow, 1961; Ainsworth et al., 1962). The later history of such children is much less clear. Retrospective studies of persons located through psychiatric clinics or delinquent groups suggest that considerable psycho-social disability persists well into adolescence. In particular, shallow feelings and loyalties, inability to form or tolerate emotional relationships, and asocial behaviour are frequently described (Bowlby, 1946; Goldfarb, 1947). However, other evidence supports at least partial spontaneous recovery (Beres and Obers, 1950; Clarke and Clarke, 1959; Stott, 1956). The adult fate of children who receive institutional care, though of compelling theoretical and practical interest, remains speculative.
