Biological reactivity to psychological stressors comprises a complex, integrated, and highly conserved repertoire of central neural and peripheral neuroendocrine responses designed to prepare the organism for challenge or threat. Developmental experience plays a role, along with heritable, polygenic variation, in calibrating the response dynamics of these systems, with early adversity biasing their combined effects toward a profile of heightened or prolonged reactivity. Conventional views of such high reactivity suggest that it is an atavistic and pathogenic legacy of an evolutionary past in which threats to survival were more prevalent and severe. Recent evidence, however, indicates that (a) stress reactivity is not a unitary process, but rather incorporates counterregulatory circuits serving to modify or temper physiological arousal, and (b) the effects of high reactivity phenotypes on psychiatric and biomedical outcomes are bivalent, rather than univalent, in character, exerting both risk-augmenting and risk-protective effects in a context-dependent manner. These observations suggest that heightened stress reactivity may reflect, not simply exaggerated arousal under challenge, but rather an increased biological sensitivity to context, with potential for negative health effects under conditions of adversity and positive effects under conditions of support and protection. From an evolutionary perspective, the developmental plasticity of the stress response systems, along with their structured, context-dependent effects, suggests that these systems may constitute conditional adaptations: evolved psychobiological mechanisms that monitor specific features of childhood environments as a basis for calibrating the development of stress response systems to adaptively match those environments. Taken together, these theoretical perspectives generate a novel hypothesis: that there is a curvilinear, U-shaped relation between early exposures to adversity and the development of stress-reactive profiles, with high reactivity phenotypes disproportionately emerging within both highly stressful and highly protected early social environments.The research on which this paper was based was supported by grants from the John D. and Catherine T.

Can the connection between psychology and neuroscience provide a sufficient framework to support the study of the development of maladaptation and psychopathology? This Special Issue is devoted to papers that address this general issue within their specific domains. If we hope to provide a definitive answer to the question posed above, then it is important to know how cognitive and affective neuroscience arose, what are their distinctive findings to date, and, to the extent possible, predict what future developments can be expected. Before proceeding, we first examine the basic principles inherent to a developmental psychopathology perspective, as well as the multiple disciplines that played a critical role in its evolution as an interdisciplinary science.We are grateful to Mary Rothbart and Sheree L. Toth for their help with this Introduction.

Borderline personality disorder (BPD) is one of the more vexing forms of psychopathology for researchers and clinicians alike to understand. Currently, the etiology and pathogenesis of the disorder remain unclear; however, steady progress has been made in several important areas that bear upon informing a more complete understanding of this condition. Long known to clinicians in office practice and mental health staff at clinics and hospitals, BPD is a heterogenous phenotype characterized by a complex array of features such as emotional dysregulation, interpersonal dysfunction, impulsivity, self-damaging behaviors, excessive anger and fear, and identity disturbance (American Psychiatric Association, 1994). The individual afflicted with BPD frequently experiences substantial social and occupational impairment, as well as frequent emotional turmoil. Those individuals who spend considerable time with a BPD-affected person, such as parents, partners, spouses, children, coworkers, and others, also encounter appreciable stresses and strains associated with the impact of BPD on the family, social, and occupational milieu.

In a recent meta-analysis, only 53% of disorganized infants were predicted by parental Unresolved states of mind on the Adult Attachment Interview (AAI). The goal of this study was to identify additional predictors of infant disorganization on the AAI by developing and validating an interview-wide coding system for Hostile/Helpless (H/H) parental states of mind with respect to attachment. Maternal AAIs were collected from 45 low-income mothers with high rates of childhood trauma when their children were age 7; Strange Situation assessments had been collected at 18 months of age. AAIs were independently coded using both the Main and Goldwyn coding system and newly developed codes for H/H states of mind. Results indicated that the H/H coding system displayed discriminant validity in that it did not overlap substantially with the Unresolved, Cannot Classify, or Fearfully Preoccupied by Traumatic Events categories in the Main and Goldwyn coding system. Second, H/H states of mind accounted for variance in disorganized infant behavior not associated with the Unresolved classification. Third, H/H states of mind were significantly related to maternal disrupted affective communication as coded by the Atypical Maternal Behavior Instrument for Assessment and Classification coding system, and maternal disrupted communication mediated the relations between H/H states of mind and infant disorganization.

Examined associations between effortful control temperament and externalizing problems in 220 3-year-old boys and girls, controlling for co-occurring cognitive and social risk factors. We also considered possible additive and/or interactive contributions of child dispositional anger and psychosocial adversity, and whether relations between effortful control and early externalizing problems were moderated by child gender. Individual differences in children's effortful control abilities, assessed using behavioral and parent rating measures, were negatively associated with child externalizing problems reported by mothers, fathers, and preschool teachers. These associations were not overshadowed by other cognitive or social risk factors, or by other relevant child temperament traits such as proneness to irritability. Further analyses revealed that associations between externalizing problem behavior and effortful control were specific to components of child problem behavior indexing impulsive-inattentive symptoms. Thus, children's effortful control skills were important correlates of children's early disruptive behavior, a finding that may provide insight into the developmental origins of chronic behavioral maladjustment.This research was supported by a grant from the National Institute of Mental Health (RO1MH57489) to Sheryl Olson and Arnold Sameroff. We are very grateful to the children, parents, teachers, and preschool administrators who participated, and to the many individuals who gave us invaluable help with data collection and coding, especially Gail Benninghoff, Meribeth Gandy Pezda, Lisa Alvarez, Sara Miceli, and Felicia Kleinberg. We also thank the administrators of the University of Michigan Children's Center for their generous assistance, Grazyna Kochanska for allowing us to use her behavioral battery of effortful control tasks, Kathy Murray for helping us with numerous details concerning the behavioral battery, and Mary Rothbart, Jack Bates, Patricia Kerig, and Thomas Power for allowing us to use their parent self-report measures.

Autistic symptoms begin in the first years of life, and recent magnetic resonance imaging studies have discovered brain growth abnormalities that precede and overlap with the onset of these symptoms. Recent postmortem studies of the autistic brain provide evidence of cellular abnormalities and processes that may underlie the recently discovered early brain overgrowth and arrest of growth that marks the first years of life in autism. Alternative origins and time tables for these cellular defects and processes are discussed. These cellular and growth abnormalities are most pronounced in frontal, cerebellar, and temporal structures that normally mediate the development of those same higher order social, emotional, speech, language, speech, attention, and cognitive functions that characterize autism. Cellular and growth pathologies are milder and perhaps nonexistent in other structures (e.g., occipital cortex), which are known to mediate functions that are often either mildly affected or entirely unaffected in autistic patients. It is argued that in autism, higher order functions largely fail to develop normally in the first place because frontal, cerebellar, and temporal cellular and growth pathologies occur prior to and during the critical period when these higher order neural systems first begin to form their circuitry. It is hypothesized that microstructural maldevelopment results in local and short distance overconnectivity in frontal cortex that is largely ineffective and in a failure of long-distance cortical–cortical coupling, and thus a reduction in frontal–posterior reciprocal connectivity. This altered circuitry impairs the essential role of frontal cortex in integrating information from diverse functional systems (emotional, sensory, autonomic, memory, etc.) and providing context-based and goal-directed feedback to lower level systems.The authors were supported by funds from the National Institute of Mental Health (2-ROI-MH36840) and National Institute of Neurological Disorders and Stroke (2-ROI-NS19855) awarded to Eric Courchesne.

We review the role of emotion regulation in borderline personality disorder (BPD). We briefly discuss the historical development of BPD as a disorder where emotional regulation plays a key role. We review the concept of emotion regulation in general and explore both one-factor and two-factor models of emotion regulation. We discuss cognitive and attentional aspects of emotion regulation, and explore these regulatory controls as operating as both voluntary as well as automatic processes. We then turn to other neurophysiological models of emotion regulation in general and examine how those models, both neurophysiologically and neuroanatomically, are expressed in individuals with BPD. We examine how neuroimaging, both anatomical and functional, reveals the roles that various neuroanatomical structures play in the regulation of emotion in BPD. We conclude by creating a neurodevelopmental model that describes how a complex matrix involving the interplay of constitutional/biological predispositions with environmental stressors as well as with parental effectiveness in response to the child's emotion expression can impact key aspects of adult cognitive, affective, interpersonal, and behavioral functioning that culminate in a diagnosis of BPD.

In two studies comprising 249 children and their families, the authors utilized secondary, exploratory data analyses to examine Boyce and Ellis' (this issue) evolutionary–developmental theory of biological sensitivity to context. The theory proposes that individual differences in stress reactivity constitute variation in susceptibility to environmental influence, both positive and negative, and that early childhood exposures to either highly protective or acutely stressful environments result in heightened reactivity. In Study 1, 127 3- to 5-year old children were concurrently assessed on levels of support/adversity in home and preschool environments and on cardiovascular reactivity to laboratory challenges. In Study 2, 122 children were prospectively assessed on familial stress in both infancy and preschool and on autonomic and adrenocortical reactivity to laboratory challenges at age 7. In both studies, a disproportionate number of children in supportive, low stress environments displayed high autonomic reactivity. Conversely, in Study 2, a relatively high proportion of children in very stressful environments showed evidence of heightened sympathetic and adrenocortical reactivity. Consistent with the evolutionary–developmental theory, the exploratory analyses also generated the testable hypothesis that relations between levels of childhood support/adversity and the magnitude of stress reactivity are curvilinear, with children from moderately stressful environments displaying the lowest reactivity levels in both studies.The research on which this paper was based was supported by grants from the John D. and Catherine T. MacArthur Foundation's Research Network on Psychopathology and Development, the National Institute of Child Health and Human Development (1RO1 HD 24718), and the National Institute of Mental Health (R01-MH44340 and P50-MH53524).

Several research groups have identified a network of regions of the adult cortex that are activated during social perception and cognition tasks. In this paper we focus on the development of components of this social brain network during early childhood and test aspects of a particular viewpoint on human functional brain development: “interactive specialization.” Specifically, we apply new data analysis techniques to a previously published data set of event-related potential (ERP) studies involving 3-, 4-, and 12-month-old infants viewing faces of different orientation and direction of eye gaze. Using source separation and localization methods, several likely generators of scalp recorded ERP are identified, and we describe how they are modulated by stimulus characteristics. We then review the results of a series of experiments concerned with perceiving and acting on eye gaze, before reporting on a new experiment involving young children with autism. Finally, we discuss predictions based on the atypical emergence of the social brain network.This work was funded by UK Medical Research Council Programme Grants (G9901005 and G9715587) to M.H.J. and S.B.C.

This article provides a contemporary view of the psychodynamics of borderline personality disorder (BPD) from a developmental psychopathology perspective. We first briefly describe the evolution of the borderline construct in psychoanalysis and psychiatry. Then we provide clinically and empirically informed model of domains of personality function and dysfunction that provides a roadmap for thinking about personality pathology from a developmental psychopathology standpoint and examine the nature and phenomenology of BPD in terms of these domains of functioning. Next, we describe prominent dynamic theories of etiology of BPD and examine these in relation to the available research. Finally, we describe psychodynamic conceptions of treatment and the way BPD phenomena manifest in treatment, followed again by consideration of relevant research, particularly on transference–countertransference constellations empirically identified in the treatment of patients with BPD.Preparation of this article was supported in part by NIMH Grants R01-MH62377 and R01-MH62378.

Children in foster care are at heightened risk for poor psychosocial outcomes. This study examined differences in two areas that may be associated with many of these outcomes, emotion understanding and theory of mind, using a sample of 3- to 5-year-old maltreated foster children (n = 60) and a comparison group of same-aged, low-income, nonmaltreated children living with their biological families (n = 31). Being in foster care was significantly associated with worse emotion understanding and theory of mind capabilities, even when accounting for age, intelligence, and executive function. There were no significant associations between length of time in foster care, number of transitions, and emotion understanding and theory of mind. Results help to expand knowledge about the cognitive and affective deficits of children in foster care and suggest that interventions targeted at these deficits include an emphasis on emotion understanding and theory of mind.Support for this research was provided by grants from NIMH (R01 MH59780 and R01 MH65046), NIMH and Office of Research on Minority Health (P30 MH46690), and NICHD (R01 HD34511).

The principal aim of this study was to assess personal relatedness and attachment patterns in 12-month-old infants of mothers with borderline personality disorder (BPD). We also evaluated maternal intrusive insensitivity toward the infants in semistructured play. We videotaped 10 mother–infant dyads with borderline mothers and 22 dyads where the mothers were free from psychopathology, in three different settings: a modification of Winnicott's Set Situation in which infants faced an initially unresponsive (“still-face”) stranger, who subsequently tried to engage the infant in a game of give and take; the Strange Situation of Ainsworth and Wittig; and a situation in which mothers were requested to teach their infants to play with miniature figures and a toy train. In relation to a set of a priori predictions, the results revealed significant group differences as follows: (a) compared with control infants, toward the stranger the infants of mothers with BPD showed lower levels of “availability for positive engagement,” lower ratings of “behavior organization and mood state,” and a lower proportion of interpersonally directed looks that were positive; (b) in the Strange Situation, a higher proportion (8 out of 10) of infants of borderline mothers were categorized as Disorganized; and (c) in play, mothers with BPD were rated as more “intrusively insensitive” toward their infants. The results are discussed in relation to hypotheses concerning the interpersonal relations of women with BPD, and possible implications for their infants' development.This research was generously supported by grants from the Winnicott Trust, the Hayward Foundation, and the Baily Thomas Charitable Fund, as well as by a Wellcome Fellowship to Matthew Patrick and an NIH Fellowship to Lisa Crandell.

A small proportion of children exhibit extreme and persistent conduct problems through childhood. The present study employed the multiple-domain model of Greenberg and colleagues as the framework for person-oriented analyses examining whether parent–child attachment combines with parenting, family ecology, and child characteristics in particular configurations of risk that are linked to this problematic developmental pathway. Using prospective data from a community sample of adolescent mothers and their children, latent variable growth mixture modeling identified a normative trajectory with declining problem behaviors during the preschool period. Consistent with research on early-starter pathways, a distinct group of children featured a higher intercept and a positive slope, indicating an escalation in disruptive behaviors. Attachment security played a role in defining specific risk profiles associated with the probability of exhibiting this problem trajectory. Given particular patterns of risk exposure, secure attachment served a protective function. Avoidant, but not disorganized, attachment was associated with significantly higher likelihood of the disruptive problem trajectory. The results also indicated the general accumulation of risk was detrimental, but the particular configuration of risk made a difference. Overall, the findings suggest early attachment operates in conjunction with personal and contextual risk to distinguish the development of later problem behaviors.This research was supported by grants from the National Institute on Drug Abuse (DA05208) and the National Institute of Mental Health (MH52400, MH56599) and a National Service Research Award (MH20010).

Maltreatment places children at risk for psychiatric morbidity, especially conduct problems. However, not all maltreated children develop conduct problems. We tested whether the effect of physical maltreatment on risk for conduct problems was strongest among those who were at high genetic risk for these problems using data from the E-risk Study, a representative cohort of 1,116 5-year-old British twin pairs and their families. Children's conduct problems were ascertained via parent and teacher interviews. Physical maltreatment was ascertained via parent report. Children's genetic risk for conduct problems was estimated as a function of their co-twin's conduct disorder status and the pair's zygosity. The effect of maltreatment on risk for conduct problems was strongest among those at high genetic risk. The experience of maltreatment was associated with an increase of 2% in the probability of a conduct disorder diagnosis among children at low genetic risk for conduct disorder but an increase of 24% among children at high genetic risk. Prediction of behavioral pathology can attain greater accuracy if both pathogenic environments and genetic risk are ascertained. Certain genotypes may promote resistance to trauma. Physically maltreated children whose first-degree relatives engage in antisocial behavior warrant priority for therapeutic intervention.We are grateful to the Study mothers and fathers, the twins, and the twins' teachers for their participation.

Borderline personality disorder (BPD) is a highly prevalent, chronic, and debilitating psychiatric problem characterized by a pattern of chaotic and self-defeating interpersonal relationships, emotional lability, poor impulse control, angry outbursts, frequent suicidality, and self-mutilation. Recently, psychopathology researchers and theorists have begun to understand fundamental aspects of BPD such as unstable, intense interpersonal relationships, feelings of emptiness, bursts of rage, chronic fears of abandonment and intolerance for aloneness, and lack of a stable sense of self as stemming from impairments in the underlying attachment organization. These investigators have noted that the impulsivity, affective lability, and self-damaging actions that are the hallmark of borderline personality occur in an interpersonal context and are often precipitated by real or imagined events in relationships. This article reviews attachment theory and research as a means of providing a developmental psychopathology perspective on BPD. Following a brief review of Bowlby's theory of attachment, and an overview of the evidence with respect to the major claims of attachment theory, I discuss individual differences, the evidence that these differences are rooted in patterns of interaction with caregivers, and how these patterns have important implications for evolving adaptations and development. Following this discussion, I present recent work linking attachment theory and BPD, focusing on the implications for understanding the etiology and treatment of BPD. In conclusion, I address some of the salient issues that point to the direction for future research efforts.

Event-related potentials (ERPs) were recorded to brief images of caregivers' and strangers' faces for 72 institutionalized children (IG), ages 7–32 months, and compared with ERPs from 33 children, ages 8–32 months, who had never been institutionalized. All children resided in Bucharest, Romania. Prominent differences in four ERP components were observed: early negative (N170), early positive (P250), midlatency negative (Nc), and positive slow wave (PSW). For all but the P250, the amplitude of these components was larger in the never instituionalized group than the institutionalized group; this pattern was reversed for the P250. Typical effects of the Nc (amplitude greater to stranger vs. caregiver) were observed in both groups; in contrast, the IG group showed an atypical pattern in the PSW. These findings are discussed in the context of the role of experience in influencing the neural circuitry putatively involved in recognizing familiar and novel faces.The work reported in this manuscript was supported by a research network (Early Experience and Brain Development) funded by the John D. and Catherine T.

This investigation examined the effects of maltreatment during the first year of life on the neural correlates of processing facial expressions of emotion at 30 months of age. Event-related potentials (ERPs) in response to children passively viewing standardized pictures of female models posing angry, happy, and neutral facial expressions were examined. Four ERP waveform components were derived: early negative (N150), early positive (P260), negative central (Nc), and positive slow wave (PSW). Differences in these waveforms between a group of 35 maltreated and 24 nonmaltreated children were reported. The groups did not differ on the early perceptual negative component (N150), whereas the maltreated children had greater P260 amplitude at frontal leads compared to the nonmaltreated children in response to viewing angry facial expressions. For the Nc component, the nonmaltreated comparison children exhibited greater amplitude while viewing pictures of happy faces compared to angry and neutral faces, whereas the maltreated children showed greater Nc amplitude at central sites while viewing angry faces. For the PSW, the nonmaltreated group showed a greater area score in the right hemisphere in response to viewing angry facial expressions compared to the maltreated group. The results are discussed in terms of brain development and function, as well as their implications for the design and evaluation of preventive interventions.This research was supported by grants from the National Institute of Mental Health (MH067792-02) and the Spunk Fund, Inc. to Dante Cicchetti.

Low positive emotionality (PE; e.g., listlessness, anhedonia, and lack of enthusiasm) has been hypothesized to be a temperamental precursor or risk factor for depression. The present study sought to evaluate the validity of this hypothesis by testing whether low PE children have similar external correlates as individuals with depression. This paper focused on the external correlate of EEG asymmetry. Previous studies have reported that individuals at risk for depression exhibited a frontal EEG asymmetry (greater right than left activity). Others have reported an association with posterior asymmetries (greater left than right activity). In the present study, children classified as having low PE at age 3 exhibited an overall asymmetry at age 5–6 with less relative activity in the right hemisphere. This asymmetry appeared to be largely due to a difference in the posterior region because children with low PE exhibited decreased right posterior activity whereas high PE children exhibited no posterior asymmetry. These findings support the construct validity of the hypothesis that low PE may be a temperamental precursor or risk factor for depression.We gratefully acknowledge Jurgen Kayser's assistance and advice.

This paper describes a conceptual approach to understanding the impact of marital violence on preschoolers, examines the predictors and mediators of child behavioral problems in a clinical sample of multiethnic preschoolers who witnessed their mothers' battering by their father figure, and presents empirical evidence supporting the use of relationship-based therapeutic modalities in treating preschoolers exposed to violence. We find that exposure to violence and maternal life stress are each predictive of child behavior problems, and that the impact of maternal life stress on child behavior problems is mediated by maternal psychopathology and the quality of the mother–child relationship.This research was funded by a grant from the National Institute of Mental Health (R21 MH 59661) and by grants from the Irving Harris Foundation and the Miriam and Peter Hass Fund.

Borderline personality disorder (BPD) is considered as a disorder of autonomy, and is related to both predisposing vulnerabilities and social relationships that fail to support basic psychological needs. Autonomy, which is defined within the self-determination theory as the capacity for self-endorsed action based on integrative, reflective awareness, is discussed as a developmental line that is dependent on specific supports from caregivers. Unresponsiveness, invalidation, or abuse by caregivers is argued to impair the capacity for autonomy and to catalyze an array of processes, both biological and psychological, which impact subsequent development and, in vulnerable individuals, can lead to BPD. Aspects of treatment, including the emphases on validation and acceptance of the patient's experience, and the cultivation of more reflective or mindful regulation of behavior, can be deduced from this analysis of autonomy disturbance, and these in turn have appeared as the cornerstones of effective treatments for BPD.
