To examine the effects of early emotional neglect on children's affective development, we assessed children who had experienced institutionalized care prior to adoption into family environments. One task required children to identify photographs of facial expressions of emotion. A second task required children to match facial expressions to an emotional situation. Internationally adopted, postinstitutionalized children had difficulty identifying facial expressions of emotion. In addition, postinstitutionalized children had significant difficulty matching appropriate facial expressions to happy, sad, and fearful scenarios. However, postinstitutionalized children performed as well as comparison children when asked to identify and match angry facial expressions. These results are discussed in terms of the importance of emotional input early in life on later developmental organization.Over the last decade, the adoption of children across nations has increased substantially. In the United States alone, such adoptions now exceed 20,000 children per year (Immigration and Naturalization Service [INS], 2002). Today, approximately 85% of international adoptees have spent some or all of their lives in institutional, as opposed to family, care where the children have experienced combinations of physical and social deprivation (US State Department, 1999). Although the deprivation experienced by these children is often impossible to precisely quantify, it is apparent that these environments fall below the quality needed to sustain normal behavioral development, as evidenced by the rate at which children arrive in their adoptive homes with poor health, growth failure, and developmental delays (Johnson, 2000a;Johnson, Miller, Iverson, Thomas, Franchino, Dole, Kiernan, Georgieff, & Hostetter, 1992;Miller, 2000). Current estimates are that institutionalized infants and toddlers loose about 1 month of linear growth for every 3 months in institutional care, with behavioral development exhibiting similar dramatic reductions (Gunnar, 2001;Johnson, 2000b).Institutionally reared children have captured attention for decades. Early research on these children emphasized the deprivation of maternal care, although as Rutter (1981) rightly noted, not only maternal stimulation, but also many other types of stimulation needed for normal development is deficient in institutional environments. Thus, the study of these children addresses both basic science issues about the role of early experience on brain development and also applied issues about the kinds of interventions that are likely to support and foster optimal development for these children. Indeed, early studies revealed that postinstitutionalized (PI) children showed marked improvements when removed from orphanage settings and placed in family environments; nonetheless, persistent developmental differences in these children could be detected long after adoption, including deficits in emotional and social development (Fisher, Ames, Chisholm, & Savoie, 1997;Hodges & Tizard, 1989...
