Heterotypic Continuity

In recent years, it has become increasingly clear that common forms of psychopathology derive from complex interactions among neurobiological vulnerabilities and environmental adversities. These interactions can alter neurobehavioral development to yield progressively intractable forms of psychopathology across childhood and adolescence. This chapter focuses on neurobiological mechanisms of trait impulsivity, trait anxiety, stress reactivity, and emotion regulation/executive function. How these traits confer vulnerability to externalizing disorders, internalizing disorders, heterotypic comorbidity, and heterotypic continuity is described. Next, neurobiological mechanisms of treatment response are considered. Trait impulsivity and trait anxiety are highly heritable and derive initially from subcortical structures that mature early in life. In contrast, emotion regulation and executive function, which modulate trait impulsivity and trait anxiety, are more sensitive to environmental influence and derive from cortical structures that mature into young adulthood. Neurobiological mechanisms of psychosocial treatment response are represented largely in the cortex and its neuromodulatory connections with the subcortex.

AbstractMost contemporary accounts of psychopathology acknowledge the importance of both biological and environmental influences on behavior. In developmental psychopathology, multiple etiological mechanisms for psychiatric disturbance are well recognized, including those operating at genetic, neurobiological, and environmental levels of analysis. However, neuroscientific principles are rarely considered in current approaches to prevention or intervention. In this article, we explain why a deeper understanding of the genetic and neural substrates of behavior is essential for the next generation of preventive interventions, and we outline 10 specific reasons why considering biological processes can improve treatment efficacy. Among these, we discuss (a) the role of biomarkers and endophenotypes in identifying those most in need of prevention; (b) implications for treatment of genetic and neural mechanisms of homotypic comorbidity, heterotypic comorbidity, and heterotypic continuity; (c) ways in which biological vulnerabilities moderate the effects of environmental experience; (d) situations in which Biology × Environment interactions account for more variance in key outcomes than main effects; and (e) sensitivity of neural systems, via epigenesis, programming, and neural plasticity, to environmental moderation across the life span. For each of the 10 reasons outlined we present an example from current literature and discuss critical implications for prevention.

AbstractElucidating the mechanisms by which infant birth conditions shape development across lengthy periods is critical for understanding typical and pathological development and for targeted early interventions. This study examined how newborns' regulatory capacities impact 10-year outcomes via the bidirectional influences of child emotion regulation (ER) and reciprocal parenting across early development. Guided by dynamic systems theory, 125 infants were tested at seven time points: birth, 3, 6, 12, and 24 months and 5 and 10 years. Initial regulatory conditions were measured by respiratory sinus arrhythmia (RSA; vagal tone) and neurobehavioral regulation (Brazelton, 1973) at birth. At each assessment between 3 months and 5 years, infant ER was microcoded from age-appropriate paradigms and mother–child reciprocity observed during social interactions. Four regulation-related outcomes were measured at 10 years: child RSA, empathy measured by mother–child conflict discussion and a lab paradigm, accident proneness, and behavior problems. An autoregressive cross-lagged structural model indicated that infant birth conditions impacted 10-year outcomes via three mechanisms. First, child ER and reciprocal parenting were individually stable across development and were each predicted by regulatory birth conditions, describing gradual maturation of ER and reciprocity over time. Second, better ER skills at one time point were related to greater reciprocity at the next time point and vice versa, and these cross-time effects defined a field of individual-context mutual influences that mediated the links between neonatal RSA and 10-year outcomes. Third, direct associations emerged between neonatal regulation and outcome, suggesting that birth conditions may establish a neurobiological milieu that promotes a more mature and resilient system. These mechanisms describe distinct “attractor” states that constrain the system's future options, emphasize the importance of defining behavior-based phenotypes of heterotypic continuity, and suggest that infants may shape their development by initiating unique cascades of individual-context bidirectional effects.

The article is devoted to the study of the temperament and behaviour of children with developmental disorder risks. Early age is most significant in terms of early identifying deviant development markers for implementing effective programmes for early intervention. The article deals with the peculiarities of using the Infant Behaviour Questionnaire - Revised (IBQ-R) and its application in scientific research; the results of domestic and foreign research into temperament as a marker/predictor of deviant behaviour are presented. The paper describes the results of a pilot study of differences in behaviour in a sample of 49 children aged 5.6 months. The research involved two groups of test children, a reference group (typically developing children) and the children of developmental risk groups (which included prematurity, family risk of autism spectrum disorders (ASD)/attention deficit and hyperactivity disorder (ADHD), paediatric arterial ischemic stroke). The significant impact of developmental disorder risks on the Perceptual Sensitivity Scale (IBQ-R) as well as the effect of sexand risks on the Approach, Vocal Reactivity (IBQ-R) scale were discovered. There are suggestions that prematurity may have a negative impact on the development of temperament in children aged 6 months. However, in comparison with such factors as the genetic predisposition to atypical development or local brain damage due to paediatric arterial ischemic stroke, prematurity (excluding extremely premature) probably has less influence on the development of temperament and behavioural characteristics. There is a significant heterotypic continuity of individual differences in temperament indicators at an early age, which highlights the need for further research into the issue and the formation of large cohorts of children. Keywords: deviant development markers, behaviour, IBQ-R questionnaire.
