Disorganized Attachment in Infancy: A Review of the Phenomenon and Its Implications for Clinicians and Policy-Makers

Disorganized/Disoriented (D) attachment has seen widespread interest from policy makers, practitioners, and clinicians in recent years. However, some of this interest seems to have been based on some false assumptions that (1) attachment measures can be used as definitive assessments of the individual in forensic/child protection settings and that disorganized attachment (2) reliably indicates child maltreatment, (3) is a strong predictor of pathology, and (4) represents a fixed or static trait of the child, impervious to development or help. This paper summarizes the evidence showing that these four assumptions are false and misleading. The paper reviews what is known about disorganized infant attachment and clarifies the implications of the classification for clinical and welfare practice with children. In particular, the difference between disorganized attachment and attachment disorder is examined, and a strong case is made for the value of attachment theory for supportive work with families and for the development and evaluation of evidence-based caregiving interventions

L'attaccamento va in tribunale: protezione e affidamento dei minori

In molti contesti professionali, compreso quello del Tribunale per i minorenni, si fa riferimento alla teoria dell’attaccamento e alla relativa ricerca, con fraintendimenti ampiamente diffusi che spesso si traducono in applicazioni scorrette. La finalità di questa dichiarazione di consenso è, pertanto, quella di migliorarne la comprensione, contrastare la disinformazione a riguardo e guidarne l’uso nel contesto del tribunale per i minorenni secondo una modalità basata sulle evidenze, considerando in particolare i processi decisionali circa la protezione e l’affidamento dei minori. L’articolo è diviso in due parti. Nella prima ci occupiamo dei problemi relativi all’utilizzo di teoria e ricerca sull’attaccamento nel contesto del Tribunale per i minorenni e ne discutiamo le ragioni. A questo proposito, esaminiamo le applicazioni della teoria che si ispirano al principio elettivo del superiore interesse del minore, discutiamo i fraintendimenti a riguardo e identifichiamo i fattori che ne hanno ostacolato un’accurata implementazione. Nella seconda parte, forniamo indicazioni per una sua adeguata e corretta applicazione. A tal fine, siamo partiti da tre principi di riferimento: il bisogno del bambino di caregiver familiari e non abusanti, il valore della continuità di cure sufficientemente buone e i benefici delle reti di relazioni di attaccamento. Discutiamo, inoltre, di quanto le valutazioni sulla qualità dell’attaccamento e sul comportamento di cura siano adeguate a ispirare i processi decisionali forensi rivolti ai minori. Concludiamo che la valutazione dei comportamenti di cura dovrebbe ricoprire un ruolo centrale. Nonostante non ci sia fra noi completo consenso riguardo all’utilizzo delle valutazioni sulla qualità dell’attaccamento nelle decisioni attinenti all’affidamento e alla protezione del minore, tali valutazioni si rivelano, al momento, le più adatte a individuare obiettivi e modalità degli interventi di sostegno. Infine, offriamo indicazioni per organizzare le future collaborazioni di ricerca interdisciplinare

Executive Functions of Six-Year-Old Boys with Normal Birth Weight and Gestational Age

Impaired fetal development, reflected by low birth weight or prematurity, predicts an increased risk for psychopathology, especially attention deficit hyperactivity disorder (ADHD). Such effects cut across the normal range of birth weight and gestation. Despite the strength of existing epidemiological data, cognitive pathways that link fetal development to mental health are largely unknown. In this study we examined the relation of birth weight (>2500 g) and gestational age (37–41 weeks) within the normal range with specific executive functions in 195 Singaporean six-year-old boys of Chinese ethnicity. Birth weight adjusted for gestational age was used as indicator of fetal growth while gestational age was indicative of fetal maturity. Linear regression revealed that increased fetal growth within the normal range is associated with an improved ability to learn rules during the intra/extra-dimensional shift task and to retain visual information for short period of time during the delayed matching to sample task. Moreover, faster and consistent reaction times during the stop-signal task were observed among boys born at term, but with higher gestational age. Hence, even among boys born at term with normal birth weight, variations in fetal growth and maturity showed distinct effects on specific executive functions

Association between perinatal methylation of the neuronal differentiation regulator HES1 and later childhood neurocognitive function and behaviour

Background: Early life environments induce long-term changes in neurocognitive development and behaviour. In animal models, early environmental cues affect neuropsychological phenotypes via epigenetic processes but as yet there is little direct evidence for such mechanisms in humans. Method: We examined the relation between DNA methylation at birth and child neuropsychological outcomes in two culturally diverse populations using a genome-wide methylation analysis and validation by pyrosequencing. Results: Within the UK Southampton Women’s Survey (SWS) we first which identified 41 differentially methylated regions of interest (DMROI) at birth associated with child’s full-scale IQ at age 4-years. Associations between HES1 DMROI methylation and later cognitive function were confirmed by pyrosequencing in 175 SWS children. Consistent with these findings, higher HES1 methylation was associated with higher executive memory function in a second independent group of 200 SWS seven-year olds. Finally, we examined a pathway for this relationship within a Singaporean cohort (n=108). Here, HES1 DMROI methylation predicted differences in early infant behavior, known to be associated with academic success. In vitro, methylation of HES1 inhibited ETS transcription factor binding, suggesting a functional role of this site. Conclusions: Thus, our findings suggest that perinatal epigenetic processes mark later neuro-cognitive function and behavior, providing support for a role of epigenetic processes in mediating the long-term consequences of early life environment on cognitive development. <br/

Attachment goes to court: child protection and custody issues

Attachment theory and research are drawn upon in many applied settings, including family courts, but misunderstandings are widespread and sometimes result in misapplications. The aim of this consensus statement is, therefore, to enhance understanding, counter misinformation, and steer family-court utilisation of attachment theory in a supportive, evidence-based direction, especially with regard to child protection and child custody decision-making. The article is divided into two parts. In the first, we address problems related to the use of attachment theory and research in family courts, and discuss reasons for these problems. To this end, we examine family court applications of attachment theory in the current context of the best-interest-of-the-child standard, discuss misunderstandings regarding attachment theory, and identify factors that have hindered accurate implementation. In the second part, we provide recommendations for the application of attachment theory and research. To this end, we set out three attachment principles: the child’s need for familiar, non-abusive caregivers; the value of continuity of good-enough care; and the benefits of networks of attachment relationships. We also discuss the suitability of assessments of attachment quality and caregiving behaviour to inform family court decision-making. We conclude that assessments of caregiver behaviour should take center stage. Although there is dissensus among us regarding the use of assessments of attachment quality to inform child custody and child-protection decisions, such assessments are currently most suitable for targeting and directing supportive interventions. Finally, we provide directions to guide future interdisciplinary research collaboration

Reactive and anticipatory looking in 6-month-old infants during a visual expectation paradigm

This article presents data from 278 six-month-old infants who completed a visual expectation paradigm in which audiovisual stimuli were first presented randomly (random phase), and then in a spatial pattern (pattern phase). Infants’ eye gaze behaviour was tracked with a 60 Hz Tobii eye-tracker in order to measure two types of looking behaviour: reactive looking (i.e., latency to shift eye gaze in reaction to the appearance of stimuli) and anticipatory looking (i.e., percentage of time spent looking at the location where the next stimulus is about to appear during the inter-stimulus interval). Data pertaining to missing data and task order effects are presented. Further analyses show that infants’ reactive looking was faster in the pattern phase, compared to the random phase, and their anticipatory looking increased from random to pattern phases. Within the pattern phase, infants’ reactive looking showed a quadratic trend, with reactive looking time latencies peaking in the middle portion of the phase. Similarly, within the pattern phase, infants’ anticipatory looking also showed a quadratic trend, with anticipatory looking peaking during the middle portion of the phase
