Article Title: Inhibitory Control and Working Memory in Post-Institutionalized Children
Authors: Emily C. Merz, Robert B. McCall, Amanda J. Wright, Beatriz Luna
Abstract: Inhibitory control and working memory were examined in post-institutionalized (PI) children adopted into United States families from Russian institutions. The PI sample originated from institutions that were less severely depriving than those represented in previous studies and approximated the level of psychosocial deprivation, which is characterized by adequate physical resources but a lack of consistent and responsive caregiving. PI children (N = 75; 29 male) ranged in age from 8–17 years (M = 12.97; SD = 3.03) and were grouped according to whether they were adopted after 14 months or before 9 months. A non-adopted comparison group (N = 133; 65 male) ranged in age from 8–17 years (M = 12.26; SD = 2.75). PI children adopted after 14 months of age displayed poorer performance on the stop-signal and spatial span tasks relative to PI children adopted before 9 months of age after controlling for age at assessment. The two PI groups did not differ in their performance on a spatial self-ordered search task. Older-adopted PI children also showed poorer spatial span task performance compared to non-adopted children, but younger-adopted PI children did not. Task performance was significantly associated with parent-rated hyperactive-impulsive behavior in everyday contexts. These findings suggest that exposure to prolonged early institutional deprivation may be linked with inhibitory control and working memory difficulties years after adoption.
Article Title: Potential Selective Responding in a Parent Questionnaire Study of Post-Institutionalized Children
Authors: Brandi N. Hawk, Amanda Wright, Megan M. Julian, Johana M. Rosas, Emily C. Merz & Robert B. McCall
Abstract: This study assesses selective responding in a single wave of data collection and a four-wave study. Participants were 121 parents of post-institutionalized children, identified as “never responders,” “previous responders,” or “wave 4 responders.” Parents evaluated their adopted child’s family, school, peer, and behavioral adjustment. Children (47% male) were 2 to 20 years old (M = 10.79, SD = 4.59) and adopted between 5 and 54 months of age (M = 15.49, SD = 9.94). Within a single wave of data collection, no evidence suggested that selective responding contributes much bias. Over a multi-wave study, however, results may under-represent adjustment difficulties.
Study Title: Timing of Intervention Affects Brain Electrical Activity in Children Exposed to Severe Psychosocial Neglect
Authors: Ross E. Vanderwert, Peter J. Marshall, Charles A. Nelson III, Charles H. Zeanah, Nathan A. Fox
Early psychosocial deprivation has profound effects on brain activity in the young child. Previous reports have shown increased power in slow frequencies of the electroencephalogram (EEG), primarily in the theta band, and decreased power in higher alpha and beta band frequencies in infants and children who have experienced institutional care.
We assessed the consequences of removing infants from institutions and placing them into a foster care intervention on brain electrical activity when children were 8 years of age. We found the intervention was successful for increasing high frequency EEG alpha power, with effects being most pronounced for children placed into foster care before 24 months of age.
The dependence on age of placement for the effects observed on high frequency EEG alpha power suggests a sensitive period after which brain activity in the face of severe psychosocial deprivation is less amenable to recovery.

Objectives To investigate the prevalence of stereotypies in children with a history of early institutional care, evaluate the efficacy of a foster care intervention compared with institutional care on the course of stereotypies, and describe correlates in language, cognition, and anxiety for children who exhibit stereotypies.
Design Randomized controlled trial.
Setting Institutions in Bucharest, Romania.
Participants One hundred thirty-six children with a history of early institutional care.
Intervention Comparison of a foster care intervention with continued care as usual in an institution.
Main Outcome Measures The presence of stereotypies as well as outcomes in language, cognition, and anxiety.
Results At the baseline assessment prior to placement in foster care (average age of 22 months), more than 60% of children in institutional care exhibited stereotypies. Follow-up assessments at 30 months, 42 months, and 54 months indicated that being placed in families significantly reduced stereotypies, and with earlier and longer placements, reductions became larger. For children in the foster care group, but not in the care as usual group, stereotypies were significantly associated with lower outcomes on measures of language and cognition.
Conclusions Stereotypies are prevalent in children with a history of institutional care. A foster care intervention appears to have a beneficial/moderating role on reducing stereotypies, underscoring the need for early placement in home-based care for abandoned children. Children who continue to exhibit stereotypies after foster care placement are significantly more impaired on outcomes of language and cognition than children without stereotypies and thus may be a target for further assessments or interventions.
Stereotypies are defined as repetitive, invariant movements with no obvious goal or function.1 Stereotypies may occasionally be seen in typically developing children but are more commonly associated with a number of different medical conditions, including autism and mental retardation. In addition, stereotypies are known to develop in association with atypical and especially restricted sensory environments or deprivation.1 The association of stereotypies with disorders of the central nervous system suggests a neurological basis, but the underlying cause, pathophysiology, and possible approaches for treatment all require further investigation.
In this article, we focus on stereotypies associated with early psychosocial deprivation. Most of our understanding of stereotypies associated with sensory-restricted environments comes from animal models. Stereotypies are the most common form of abnormal behavior found in caged animals, and animal models of deprivation-induced stereotypies have been found across many species. In these animal models, stereotypies have been linked to alterations in the cortical–basal ganglia circuitry.
Human models of severe psychosocial deprivation in early childhood are understandably more limited. However, there are case reports of previously healthy children who developed stereotypies after exposure to prolonged extreme deprivation. In 1 case, a typically developing, healthy, 3-year-old girl in Thailand exhibited a number of motor stereotypies after being isolated in a cage for 6 years. Four years after her reintegration into the community, she showed considerable improvement including the elimination of stereotypies, but she continued to have many developmental difficulties, particularly with speech.
Children raised in institutions provide another unfortunate but important group in which to study the effects of extreme early psychosocial deprivation, including the presence of stereotypies. Institutionalized children are known to exhibit deficits across numerous domains of functioning, including physical, psychiatric, and cognitive outcomes. There are a few reports in the literature suggesting an increased incidence and severity of motor stereotypies in this population, believed to be caused by the restricted sensory environment limiting typical input. Hypotheses for the functional significance of stereotypies in this environment include attempts at self-stimulating, coping mechanisms for self-soothing, or expressions of frustration or anxiety, particularly in children who lack adequate verbal communication skills.
An important issue that has not been addressed to date, to our knowledge, is a systematic study of the reduction or elimination of deprivation-induced stereotypies by restitution of enhanced caregiving environments. One report in the literature suggests a reduction in stereotypies after adoption and calls for additional research in this area. In this study of 46 children adopted from Romanian orphanages by families in British Columbia, Canada, 84% of caregivers reported the presence of stereotypies at the time of placement. The average age of the children at adoption was 18.5 months, and the mean time spent in institutions prior to adoption was 17.5 months. By the time the interview for the study was conducted (a median of 11 months after placement with the adopted family), 98% of stereotyped behavior problems were reported by caregivers to have shown some improvement or to be completely resolved. However, since children in this study were not randomly assigned to foster care placement, the application of these results to all children with a history of early institutional care is limited by selection bias. In addition, the study reports findings from only 1 assessment after placement and therefore does not provide data on stereotypies at later ages.
In the current study, we draw on data from the Bucharest Early Intervention Project (BEIP), a study of current and formerly institutionalized children in Romania. The BEIP is unique in its ability to evaluate directly the effects of early family placement rather than institutional care for young children because the participants were institutionalized children randomly assigned either to continued care as usual in the institution or to a foster care intervention. The BEIP is the first such randomized clinical trial to evaluate foster care as an alternative to institutional care for abandoned children. Because the children enrolled in this study were closely followed up longitudinally, this study also provides the unusual opportunity within the population of institutionalized children to investigate the course of stereotypies in children exposed to extreme deprivation and the presence of sensitive periods for the development or remediation of stereotypies.
This study addressed the following questions: (1) How many young children being raised in institutions exhibit stereotypies? (2) For children with a history of early institutionalization, does placement in a foster care intervention reduce or eliminate stereotypies? If so, is there an effect of timing of placement? (3) To characterize those children who continue to exhibit stereotypies compared with those whose stereotypies resolve, are there any correlates of stereotypies that we can identify in this population, particularly focusing on outcomes in language, cognition, and anxiety?
Study Title: Parent-Reported Executive Functioning in Postinstitutionalized Children: A Follow-Up Study
Authors: Emily Merz, Robert McCall, Victor Groza
Abstract: This study compared parent-rated executive functioning (EF) in 6- to 18-year-old children adopted from psychosocially depriving institutions to that in children adopted from severely or “globally” depriving institutions. Individual continuity in EF over 2 years was examined in children adopted from psychosocially depriving institutions. There were 471 children adopted from psychosocially depriving Russian institutions that provided adequate physical resources but failed to provide a consistent set of responsive caregivers. There were 111 children adopted in the early 1990s from globally depriving Romanian institutions that were characterized by physical deprivation as well as profound psychosocial neglect. Adoptive parents completed a background questionnaire and the Behavior Rating Inventory of Executive Function (BRIEF). Children adopted from globally depriving institutions had significantly higher levels of EF difficulties than children adopted from psychosocially depriving institutions. For both groups, adoption after 18 months of age was associated with higher levels of EF difficulties. Children adopted from globally depriving institutions had higher levels of EF difficulties than the BRIEF standardization sample at younger ages at adoption. There was moderate to strong continuity in EF difficulties over 2 years in children adopted from psychosocially depriving institutions. These findings suggest that more severe early deprivation may lead to a higher risk of later EF difficulties, which may persist over time.
