RESUMO

We investigated neural correlates of traumatic experience related to the lack of family care in adults with a history of institutionalization (IC) using the Emotional Stroop paradigm. The goals of our study were twofold: we investigated whether adults with IC history (n = 24; Mage  = 22.17, SD = 6.7) demonstrate atypical processing of emotionally salient words in general, and whether they exhibit selective processing bias toward family related words compared to adults raised in biological families (BFC; n = 28; Mage  = 22.25, SD = 4.9). Results demonstrated significant differences in accuracy but not response times between groups on the behavioral level, indicating that the IC group was overall less accurate in identifying the color of the font. Contrary to our prediction, there were no significant differences between neural response to family related versus unrelated words in the IC and BFC groups. The absence of group differences can be explained by the selection of stimuli, which were associated with family rather than institutional history. The IC group showed a larger N280-380 component in response to negative words compared to the BFC group, and larger negativity in the right parietal area in response to positive words in the same time window. Results demonstrate that institutional history is marked by altered emotional processing in the subpopulation of institutional care-leavers, but the footprint is not specific to traumatic experience and extends from general sensitivity to emotional words.

RESUMO

A number of studies to this day have examined the role of maternal childhood trauma in parenting styles, mental health, and child attachment patterns; however, there are limited data on parenting of mothers who were raised in institutional care (IC) and involved in the child welfare system. The current review focuses on maternal history of institutionalization and foster care placement and its impact on parenting and child development. Studies show that the history of maternal trauma such as maltreatment, which is often linked to an orphan status, can be transferred to children through maladaptive parenting strategies, evoking a cycle of cross-generational maltreatment. Mothers raised in institutions show an early sexual debut that is often resulting in unplanned pregnancies, and are lacking competence in taking care of their own children. Directions for future research involving mothers with a history of IC are discussed.

RESUMO

The current study investigated language development of children residing in institutional care (IC) in Russia, compared to peers raised by biological family care (BFC). We used standardized behavioral testing (Preschool Language Scale-5, McArthur CDI), and an event-related potential picture-word matching paradigm. Children in IC significantly underperformed on the measures of receptive and expressive language development, with larger deficits in expressive domain. ERP findings indicated that children in IC did not demonstrate significant N400 effect in response to semantic violations; there were no significant group differences in semantic processing between IC and the BFC groups. In the late time window of 400-600 ms, phonologically legal pseudowords elicited an ERP component with the positive amplitude in the IC group, resembling P300 ERP component, whereas the BFC group showed the expected N400 effect. The findings point to less efficient lexical processing in the IC group. To the best of our knowledge, this study is the first to investigate both the behavioral and neuropsychological aspects of language development, focusing on phonological and lexical-semantic processing, in children who currently live in IC.

RESUMO

The current study investigated the long-term effects of institutionalization on the inhibitory control of young adults raised in orphanages using the color-word Stroop task. We examined whether young adults raised in institutions (IC group; n = 24; M = 22.17 years, SD = 6.7) would demonstrate poorer behavioral performance and atypical neural response to incongruent stimuli compared to their peers raised in biological families (Biological Family Care, BFC group; n = 28; M = 22.25 years, SD = 4.9). Accuracy analysis revealed that all participants were less accurate in the incongruent condition, however, no group differences were found. Reaction time analysis showed that the institutional care (IC) group was overall slower than the BFC. No significant differences in neural response to stimuli incongruence were identified. The absence of group differences in the interference condition can be explained by the low complexity of the Stroop task in the current study. The IC group showed a reduced P3 event-related potential component on both the congruent and incongruent trials. Findings suggest general attention difficulties in this population, rather than inhibitory control deficits.

RESUMO

Using a newly developed Assessment of the Development of Russian Language (ORRIA), we investigated differences in language development between rural vs. urban Russian-speaking children (n = 100 with a mean age of 6.75) subdivided into groups with and without developmental language disorders. Using classical test theory and item response theory approaches, we found that while ORRIA displayed overall satisfactory psychometric properties, several of its items showed differential item functioning favoring rural children, and several others favoring urban children. After the removal of these items, rural children significantly underperformed on ORRIA compared to urban children. The urbanization factor did not significantly interact with language group. We discuss the latter finding in the context of the multiple additive risk factors for language development and emphasize the need for future studies of the mechanisms that underlie these influences and the implications of these findings for our understanding of the etiological architecture of children's language development.

RESUMO

Some children with autism spectrum disorders (ASD) demonstrate unusual islets of abilities or "splinter skills" that represent relative strengths in their development. In this paper we present a clinical case of an 11-year-old Russian boy with ASD who spontaneously acquired the English language. While the child demonstrated language deficits in both English and Russian, the discrepancy between the languages was paradoxical given the lack of exposure to English language. This case study brings into question the importance of a language environment for children with ASD. Alternative pathway to language acquisition is discussed. We hypothesize that that incidental second language acquisition in children with ASD resulting from media exposure could become more frequent with the availability of the Internet.

RESUMO

We investigated the magnitude and direction of differences in parenting styles as they relate to children's mental health problems, as assessed using the CBCL. The sample consisted of 306 families residing in a large industrial city in Russia. We aimed to expand the cross-cultural literature on parenting styles by assessing a sample of Russian families and analyzing how agreement versus disagreement between self-reported and partner-reported parenting styles related to children's mental health problems. The findings suggested that both congruence and incongruence between parenting styles could be associated with children's mental health problems. When parents agreed about high warmth and matched on lower levels of demandingness, in line with the permissive parenting style, children tended to exhibit maladaptive behavior and externalizing problems. We also registered that children were likely to show low levels of mental health problems when fathers had higher self-reported warmth compared with mothers' reports. In contrast, children whose fathers had higher self-reported demandingness compared with the mothers' reports, exhibited moderate levels of mental health problems. This study expands the existing literature by providing a dimensional approach to children's mental health difficulties in the context of (dis)agreements in the parenting styles within a family.

RESUMO

While there has been an increase in studies investigating the relationship between endogenous oxytocin (OXT) concentrations and human social interactions over the past decades, these studies still seem far from converging, both in methodological terms and in terms of their results. This systematic review and meta-analysis were aimed at a comprehensive evaluation and synthesis of empirical evidence on the relationship between endogenous OXT concentrations and human social interactions by reviewing studies published between 1970 and July 2020 and addressing various related methodological and analytical limitations. Sixty-three studies were included in the qualitative synthesis, and results from 51 studies were pooled in a meta-analysis (n = 3,741 participants). The results indicated that social interaction did not lead to an expected hormonal response in causal designs, either in a pre-post design (g = 0.079) or when comparing experimental conditions with and without social interaction (g = 0.256). However, in correlational designs, the overall mean effect size (ES) of the correlations between indicators of social interaction and OXT concentrations was significantly different from zero (z = 0.137). In both designs, subgroup analyses revealed that studies involving either parent-child interactions, or the utilization of the enzyme-linked immunosorbent assay method for OXT analysis, or unrestricted eating, drinking, or exercise before biofluid collection showed significantly higher than zero mean ESs. This review exposes the observed inconsistencies and suggests that standardized, replicable, and reliable approaches to assessing social interaction and measuring OXT concentrations need to be developed to study neurochemical mechanisms of sociality in humans.

RESUMO

Although learning disorders (LD) and developmental language disorder (DLD) can be linked to overlapping psychological and behavioral deficits, such as phonological, morphological, orthographic, semantic, and syntactic deficits, as well as academic (e.g., reading) difficulties, they are currently separate diagnoses in the DSM-5 with explicit phenotypic differences. At a neural level, it is yet to be determined to what extent they have overlapping or distinct signatures. The identification of such neural markers/endophenotypes could be important for the development of physiological diagnostic tools, as well as an understanding of disorders across different dimensions, as recommended by the Research Domain Criteria Initiative (RDoC). The current systematic review and meta-analysis examined whether the two disorders can be differentiated based on the auditory brainstem response (ABR). Even though both diagnoses require hearing problems to be ruled out, a number of articles have demonstrated associations of these disorders with the auditory brainstem response. We demonstrated that both LD and DLD are associated with longer latencies in ABR Waves III, V, and A, as well as reduced amplitude in Waves V and A. However, multilevel subgroup analyses revealed that LD and DLD do not significantly differ for any of these ABR waves. Results suggest that less efficient early auditory processing is a shared mechanism underlying both LD and DLD.

RESUMO

Children abandoned to institutions display a host of developmental delays, including those involving general cognition and language. The majority of published studies focus on children over 3 years of age; little is known about whether these delays may be detected earlier when children undergo rapid lexical development. To investigate the early language development of children raised in institutional settings in the Russian Federation, we compared a group of children in institutional care (n = 36; 8-35 months) to their age-matched peers raised in biological families, who have never been institutionalized (n = 72) using the Russian version of the CDI. The results suggest that institutionalization is associated with pronounced delays in children's early language development with large and robust effect sizes. Among children with a history of institutionalization, these delays are also associated with difficulties in Daily Living skills, communication, and socialization.

RESUMO

The study shows that whole-exome sequencing is a promising approach to detect novel variants-and gene candidates in DSD, that, as a future direction, may improve the diagnostic gene panels for this heterogeneous disorder.

RESUMO

The attunement of speech perception/discrimination to the properties of one's native language is a crucial step in speech and language development at early ages. Studying these processes in young children with a history of institutionalization is of great interest, as being raised in institutional care (IC) may lead to lags in language development. The sample consisted of 82 children, split into two age groups. The younger age group (<12 months) included 17 children from the IC and 17 children from the biological-family-care (BFC) group. The older group (>12 months) consisted of 23 children from the IC group, and 25 children from the BFC group. A double-oddball paradigm with three consonant-vowel syllables was used, utilizing native (Russian) and foreign (Hindi) languages. A Mismatch Negativity (MMN) component was elicited within a 125-225 ms time window in the frontal-central electrode. Findings demonstrate the absence of MMN effect in the younger age group, regardless of the living environment. Children in the older group are sensitive to native deviants and do not differentiate foreign language contrasts. No significant differences were observed between the IC and BFC groups for children older than 12 months, indicating that children in the IC have typical phonological processing. The results show that the MMN effect is not registered in Russian speaking children before the age of 12 months, regardless of their living environment. At 20 months of age, institutionally reared children show no evidence of delays in phonetic development despite a limited experience of language.

RESUMO

Impoverished early care environments are associated with developmental deficits in children raised in institutional settings. Despite the accumulation of evidence regarding deficits in general cognitive functioning in this population, less is known about the impact of institutionalization on language development at the level of brain and behavior. We examined language outcomes in young adults and adolescents raised in institutions (n = 23) as compared to their socioeconomic status and age peers raised in biological families (n = 24) using a behavioral language assessment and linguistic event-related potentials (ERPs). Controlling for intelligence, adults with a history of institutionalization demonstrated deficits in lexical and grammatical development and spelling. Analyses of ERP data revealed significant group differences in the dynamic processing of linguistic stimuli. Adults with a history of institutionalization displayed reduced neural sensitivity to violations of word expectancy, leading to reduced condition effects for temporo-spatial factors that tentatively corresponded to the N200, P300/N400, and phonological mismatch negativity. The results suggest that language is a vulnerable domain in adults with a history of institutionalization, the deficits in which are not explained by general developmental delays, and point to the pivotal role of early linguistic environment in the development of the neural networks involved in language processing.

RESUMO

Early social deprivation (i.e., an insufficiency or lack of parental care) has been identified as a significant adverse early experience that may affect multiple facets of child development and cause long-term outcomes in physical and mental health, cognition and behavior. Current research provides growing evidence that epigenetic reprogramming may be a mechanism modulating these effects of early adversities. This work aimed to investigate the impact of early institutionalization-the immersion in an extreme socially depriving environment in humans-on the epigenome and adaptive behavior of young children up to 4 years of age. We conducted a cross-sectional study involving two comparison groups: 29 children raised in orphanages and 29 children raised in biological families. Genome-wide DNA methylation profiles of blood cells were obtained using the Illumina MethylationEPIC array; the level of child adaptive functioning was assessed using the Vineland Adaptive Behavior Scales-II. In comparison to children raised in families, children residing in orphanages had both statistically significant deficits in multiple adaptive behavior domains and statistically significant differences in DNA methylation states. Moreover, some of these methylation states may directly modulate the behavioral deficits; according to preliminary estimates, about 7-14% of the deviation of adaptive behavior between groups of children may be determined by their difference in DNA methylation profiles. The duration of institutionalization had a significant impact on both the adaptive level and DNA methylation status of institutionalized children.
