Early Health Risk Factors for Violence: Conceptualization, Review of the Evidence, and Implications

Violence and aggression are public health problems that can benefit from ongoing research into risk reduction and prevention. Current developmental theories of violence and aggression emphasize biological and psychosocial factors, particularly during adolescence. However, there has been less focus on understanding the interactive, multiplicative effects of these processes. Furthermore, little attention has been given to the pre-, peri-, and postnatal periods, where prevention and intervention may yield effective results. Early health risk factors that influence negative behavioral outcomes include prenatal and postnatal nutrition, tobacco use during pregnancy, maternal depression, birth complications, traumatic brain injury, lead exposure, and child abuse. There is an ample literature to suggest that these early health risk factors may increase the likelihood of childhood externalizing behaviors, aggression, juvenile delinquency, adult criminal behavior, and/or violence. This paper proposes an early health risk factors framework for violence prediction, built on existing developmental theories of criminal behavior and supported by empirical findings. This framework addresses gaps in the adolescent psychopathology literature and presents a novel conceptualization of behavioral disturbance that emphasizes the pre-, peri-, and post-natal periods, when a child's development is critical and the opportunity for behavioral and environmental modification is high. Implications for such a framework on violence prevention programs are discussed.     

Should the behavioral sciences become more pragmatic? The case for functional contextualism in research on human behavior

Although societal need for behavioral science research is enormous, current research practices seem to be inefficient vehicles for producing knowledge that guides practical action. Many of our most popular theories provide little direct guidance for application. They focus on the development of models of the relationships among organismic events such as attitudes, self-efficacy expectations, and behavior, but pay little or no attention to the contextual influences on behavior. Such research is in keeping with a long-standing mechanistic tradition in psychology. We propose a version of contextualism as an alternative paradigm for the behavioral sciences. According to this paradigm, theories and research are evaluated in terms of their contribution to the prediction and influence of behavior. Basic research organized to pursue this goal has a direct bearing on how behavioral phenomena can be changed for practical purposes. Conversely, applied research contributes to basic understanding of the determinants of psychological phenomena.     

A contextual approach to research on AIDS prevention

The acquired immune deficiency syndrome (AIDS) is a disease that is transmitted almost entirely through behavioral factors. In the absence of a cure or vaccine, the modification of AIDS-risk behavior presents a unique challenge to behavioral scientists and should be taken as a clear imperative by behavior analysts. This paper discusses the currently dominant social-cognitive theories (the health belief model, the theory of reasoned action, and self-efficacy theory) that have been widely used to predict and understand AIDS-risk behavior. Although these theories have generated a voluminous literature on the cognitive, attitudinal, and demographic correlates of AIDS-risk behavior, they have not resulted in specific intervention strategies to influence risky behavior, most likely because they fail to specify manipulable variables. As an alternative to social-cognitive theories, this paper evaluates the usefulness of a behavior-analytic approach to stem the spread of HIV infection. It examines some of the philosophical differences underlying cognitive and behavioral approaches that are embedded in mechanistic versus functional contextualistic principles. It explores the theoretical and practical implications of adopting either predicting and explaining behavior or predicting and influencing behavior as the goals of science. To illustrate the value of adopting the goal of prediction and influence, behavior-analytic research on the social context of risky sexual behavior in adolescents is described. The paper argues that in order to alter the future course of the AIDS epidemic, the behavioral sciences must move beyond describing cognitive and attitudinal correlates of risky behavior and focus on the social context of the behavior of individuals. In addition, population-wide changes in AIDS-risk behavior can be accomplished only if research focuses on how to influence larger social systems, including the media, school systems, and community organizations.     

Women's mental health during pregnancy influences fetal and infant developmental and health outcomes

Women's mental health during pregnancy has important implications not only for the well-being of the mother, but also for the development, health, and well-being of her unborn child. A growing body of empirical evidence from population-based studies suggests that two indicators of women's mental health during pregnancy--psychosocial stress and social support--may exert a significant influence on fetal development and infant birth outcomes, such as birth weight and length of gestation, even after controlling for the effects of established sociodemographic, obstetric, and behavioral risk factors. This paper describes the role of three major biological systems involved in the physiology of pregnancy and stress physiology: neuroendocrine, immune/inflammatory, and cardiovascular systems. These systems have been hypothesized to mediate the effects of maternal mental health on fetal developmental and health outcomes, and a central role has been proposed for placental corticotropin-releasing hormone in this process. However, not all women reporting high prenatal stress and/or low social support proceed to develop adverse birth outcomes, raising the question of the determinants of susceptibility/vulnerability in the context of high stress and/or low social support. In this context, the role of race/ethnicity and genetic predisposition are discussed as two promising avenues of further investigation.     

The persistence of dichotomies in the study of behavioral development

The inadequacies of dichotomous views of behavioral development that oppose learned and innate behavior, or genetic and environmental determinants of behavior, have long been recognized. However, they continue to exert a powerful influence on current thinking about development, often by way of metaphors that simply recast these old ideas in a more modern technical vocabulary. The idea that the information for behavior can be attributed to either genetic or environmental sources was originated by Lorenz and provides the basis for many current dichotomous accounts of behavioral development. Lorenz's “sources of information” metaphor for development is fundamentally flawed, however, as are those more recent accounts that are based on it. The alternative interactionist account of development, most clearly articulated by Lehrman, is a far more powerful and coherent theoretical framework for development, but it has not been broadly assimilated into psychology and continues to be widely misunderstood. In particular, the interactionist account does not involve a radical environmentalism, does not attribute all behavior to the effects of learning, and does not interpret development as a gene-environment interaction. The attractive simplicity of dichotomous thinking encourages its continued application to the study of development despite the fact that it is clearly inadequate to the complexities of developmental analysis.     

Developmental theories of parental contributors to antisocial behavior

In view of the increased interest in a developmental approach to psychopathology, and mounting evidence of the importance of parent-child interactions in the etiology of early antisocial behavior, the following questions were posed for this review. What theories of parent-child relationships and family management techniques are available? How developmental are they, how specific and transactional are they relative to parent and child behaviors involved? And how well do they cover the period in which antisocial behavior develops? Six theories have some developmental features but the attachment theories (by L. A. Sroufe, B. Egeland, and M. T. Greenberg) and two social learning theories (by G. R. Patterson and J. Martin) are most clearly developmental. They postulate reciprocal interactions of parent and child, and transformations in the form of normative changes in the child or changes in family processes. The social learning theories of Patterson and Martin are most specific, microanalytic in fact, as to the interaction processes involved, and the attachment theories at least specify kinds of behavior involved and also do not rely on traits or types of influence as their units of analysis. Conceptualization is most weak and overly general between late infancy and the preschool years. This gap makes it difficult to link attachment and social learning theories, both of which have driven a large number of studies. A bridging theory is offered to link the two sets of theories in the critical period involved.

Abstract

This paper studies the interaction of the clinical theories of two major British theorists, Melanie Klein and Donald Winnicott. Through three clinical examples, we see how the “Klein-Winnicott dialectic” operates in a significantly developmental fashion to advance and fulfill clinical work. Winnicott’s “object survival” is looked at in developmental conjunction with Klein’s “mourning” as a primary clinical and developmental process. This interaction also captures the essence of working with the aggression of a self that has been traumatically disrupted within its early development. This paper demonstrates how such work leads to the assimilation and grieving of primal object loss, evolving into a “developmental mourning process.” This developmental mourning includes the working-through of an “abandonment depression” in the character-disordered patient. A clinical example in a 1989 essay on “psychic pain” by Betty Joseph is used to set up the clinical challenge of going beyond the symptomatic clinging behavior of developmental arrest, into full psychic birth as a separate other, an Other who can relate to an Other. Conclusively, the subjective visceral affect noted and monitored in its clinical dimensions here is that of human “heartache,” which can also include regret.     

A quantitative assessment of the effects of malnutrition on behavioral development in laboratory mice

The aim of this study was to compare the effects of malnutrition on behavioral development in mice with those due to heredity obtained in a previous study. To this end behavioral development was assessed using a developmental time scale which allowed comparison of the two studies. Pregnant B6D2F1/J mice were maintained on either a protein restricted or normal protein diet from Day 7 to Day 24 postconception, at which time the low protein group was returned to the normal diet until behavioral testing at Day 32. Behavioral development in the control group replicated the values obtained in previous studies, whereas the malnourished pups were retarded by 1.4 days. This was of the same order of magnitude as that reported previously for maternal inbreeding. Measures of maternal and pup body weight at birth, Day 24 and Day 32 indicated that although the malnourished animals were initially significantly lighter in weight they had recovered by Day 32. Litter size however, declined between birth and time of behavioral testing in the malnourished group.     

Social Neuroscience: Progress and Implications for Mental Health

ABSTRACT— Social neuroscience is a new, interdisciplinary field devoted to understanding how biological systems implement social processes and behavior. Social neuroscience capitalizes on biological concepts and methods to inform and refine theories of social behavior, and it uses social and behavioral constructs and data to inform and refine theories of neural organization and function. We focus here on the progress and potential of social neuroscience in the area of mental health. Research in social neuroscience has grown dramatically in recent years. Among the most active areas of research we found are brain-imaging studies in normal children and adults; animal models of social behavior; studies of stroke patients; imaging studies of psychiatric patients; and research on social determinants of peripheral neural, neuroendocrine, and immunological processes. We also found that these areas of research are proceeding along largely independent trajectories. Our goals in this article are to review the development of this field, examine some currently promising approaches, identify obstacles and opportunities for future advances and integration, and consider how this research can inform work on the diagnosis and treatment of mental disorders.     

Affect regulation, brain development, and behavioral/emotional health in adolescence

This paper addresses the importance of affect regulation (AR) in relation to a broad range of behavioral and emotional health problems that emerge during adolescence. AR is defined as the adaptive modulation of emotional experience to serve a goal or purpose. This conceptualization of AR emphasizes the use of cognitive skills to guide, inhibit, or modify emotion and behavior, including the expression of emotional responses, in learned, strategic ways-skills that ultimately underpin adult levels of social maturity and the ability to show "responsible" behavior across a range of emotional situations. Neurobehavioral systems that subserve these AR skills include areas of the inferior and orbital prefrontal cortex (PFC), with rich interconnections to several limbic structures and other cortical areas, including the dorsolateral PFC. Adolescence represents an important developmental period in the functional maturation of adult AR skills; it is also a critical time in the development of clinical disorders of AR (eg, rates of depression increase dramatically and gender differences in depression emerge). Maturational changes in AR that occur during adolescence-particularly with respect to the role of emotions influencing responsible decision making-are also relevant to understanding key aspects of the developmental pathways of some behavioral health problems, such as alcohol use and nicotine dependence. A strong case is made for developmental research in affective neuroscience aimed at this important maturational period, particularly the kind of transdisciplinary research leading toward mechanistic understanding of the development of adolescent-onset disorders. Improving understanding in these areas could ultimately lead to the development of early interventions in targeted high-risk populations, and has enormous clinical and social policy relevance.     

A dynamic developmental theory of attention-deficit/hyperactivity disorder (ADHD) predominantly hyperactive/impulsive and combined subtypes

Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. Inattentiveness, overactivity, and impulsiveness are presently regarded as the main clinical symptoms. The dynamic developmental behavioral theory is based on the hypothesis that altered dopaminergic function plays a pivotal role by failing to modulate nondopaminergic (primarily glutamate and GABA) signal transmission appropriately. A hypofunctioning mesolimbic dopamine branch produces altered reinforcement of behavior and deficient extinction of previously reinforced behavior. This gives rise to delay aversion, development of hyperactivity in novel situations, impulsiveness, deficient sustained attention, increased behavioral variability, and failure to "inhibit" responses ("disinhibition"). A hypofunctioning mesocortical dopamine branch will cause attention response deficiencies (deficient orienting responses, impaired saccadic eye movements, and poorer attention responses toward a target) and poor behavioral planning (poor executive functions). A hypofunctioning nigrostriatal dopamine branch will cause impaired modulation of motor functions and deficient nondeclarative habit learning and memory. These impairments will give rise to apparent developmental delay, clumsiness, neurological "soft signs," and a "failure to inhibit" responses when quick reactions are required. Hypofunctioning dopamine branches represent the main individual predispositions in the present theory. The theory predicts that behavior and symptoms in ADHD result from the interplay between individual predispositions and the surroundings. The exact ADHD symptoms at a particular time in life will vary and be influenced by factors having positive or negative effects on symptom development. Altered or deficient learning and motor functions will produce special needs for optimal parenting and societal styles. Medication will to some degree normalize the underlying dopamine dysfunction and reduce the special needs of these children. The theory describes how individual predispositions interact with these conditions to produce behavioral, emotional, and cognitive effects that can turn into relatively stable behavioral patterns.     

Is an epigenetic switch the key to persistent extinction?

Many studies of learning have demonstrated that conditioned behavior can be eliminated when previously established relations between stimuli are severed. This extinction process has been extremely important for the development of learning theories and, more recently, for delineating the neurobiological mechanisms that underlie memory. A key finding from behavioral studies of extinction is that extinction eliminates behavior without eliminating the original memory; extinguished behavior often returns with time or with a return to the context in which the original learning occurred. This persistence of the original memory after extinction creates a challenge for clinical applications that use extinction as part of a treatment intervention. Consequently, a goal of recent neurobiological research on extinction is to identify potential pharmacological targets that may result in persistent extinction. Drugs that promote epigenetic changes are particularly promising because they can result in a long-term molecular signal that, combined with the appropriate behavioral treatment, can cause persistent changes in behavior induced by extinction. We will review evidence demonstrating extinction enhancements by drugs that target epigenetic mechanisms and will describe some of the challenges that epigenetic approaches face in promoting persistent suppression of memories.     

Alarm call responsivity of mallard ducklings: The inadequacy of learning and genetic explanations of instinctive behavior

Traditional conceptions of learning do not adequately account for the development of species-typical behavior. Developmental theory, though, can account for learning phenomena, as well as seemingly innate behavior. Developmental theory also focuses on subtle, nonobvious, as well as obvious, forms of experience throughout the life span, including the prenatal period. To illustrate the developmental approach, data on the ontogeny of alarm call responsivity in mallard ducklings (Anas platyrhynchos) are presented. This research, which was conducted both in the field and in the laboratory, identifies the particular acoustic feature of alarm calls to which ducklings are sensitive. Additional experiments have shown that normally occurring perinatal auditory experience is required for the development of behavioral inhibition (i.e., “freezing”). These experiments demonstrate the ability of developmental theory to account for phenomena that elude other, more traditional, theories.

Developmental changes in the responses of preterm infants to a painful stressor

The purpose of this investigation was to examine longitudinally gestational age and developmental differences in preterm infants' self-regulatory abilities in response to a painful stressor, as well as associations between behavioral and cardiovascular responses. Participants included 49 healthy premature infants. Behavioral and cardiovascular responses to a heel stick blood draw were compared between infants of 28-31 and 32-34 weeks' gestation age at birth. Both gestational age groups displayed behavioral and cardiovascular indications of stress in response to the blood draw. However, both shortly after birth and several weeks later, infants born at younger gestational ages (28-31 weeks) were more physiologically reactive. Evidence that the behavioral stress responses of 28-31 weeks' gestation age group preterm infants do not reflect their physiological responses suggests that evaluation of preterm infants' experiences and risk require assessments of both physiology and behavior. The greater stress vulnerability of the 28-31 weeks' gestation group relative to the 32-34 weeks' gestation group and the implications of this for subsequent development are discussed.     

Developmental regression in autism spectrum disorders

The occurrence of developmental regression in autism is one of the more puzzling features of this disorder. Although several studies have documented the validity of parental reports of regression using home videos, accumulating data suggest that most children who demonstrate regression also demonstrated previous, subtle, developmental differences. Counter to clinical intuition, the earlier development of social, language, and attachment behaviors followed by regression does not seem to support later recovery of skills or better developmental outcomes compared to children who never had speech or typical social responsivity. In fact, this regressive group may have somewhat greater developmental impairment than the nonregressive group, though the two groups do not appear to present different behavioral phenotypes. Although autism is not the only condition in which regression occurs, it appears to be the most frequent condition. Other disorders that demonstrate an early regression with no known etiology include total blindness from birth and childhood disintegrative disorder, both of which demonstrate behavioral relations to autism. In addition, two biological conditions with known etiologies also involve regression with some behaviors resembling autism behavioral phenotype: Rett syndrome (a genetic disorder; see Glaze, this issue) and Landau-Kleffner syndrome (see McVicar and Shinnar, this issue), which involves a seizure disorder.     

BEHAVIORAL CUSPS: A DEVELOPMENTAL AND PRAGMATIC CONCEPT FOR BEHAVIOR ANALYSIS

Most concepts of development explain certain behavior changes as products or markers of the invariable succession of emerging periods, stages, refinements, or achievements that define and order much of an individual's life. A different but comparable concept can be derived from the most basic mechanisms of behavior analysis, which are its environmental contingencies, and from its most basic strategy, which is to study behavior as its subject matter. From a behavior-analytic perspective, the most fundamental developmental questions are (a) whether these contingencies vary in any systematic way across the life span, and thus make behavior change in a correspondingly systematic way; and (b) whether some of these contingencies and their changes have more far-reaching consequences than others, in terms of the importance to the organism and others, of the behavior classes they change. Certain behavior changes open the door to especially broad or especially important further behavior change, leading to the concept of the behavioral cusp. A behavioral cusp, then, is any behavior change that brings the organism's behavior into contact with new contingencies that have even more far-reaching consequences. Of all the environmental contingencies that change or maintain behavior, those that accomplish cusps are developmental. Behavior change remains the fundamental phenomenon of development for a behavior-analytic view; a cusp is a special instance of behavior change, a change crucial to what can come next.

Theories,structures and simulations in the research of early mentalizing

The objective of this paper is to propose some new approaches that could be used in the research of the development of mindreading in infancy. I argue that the mentalizing system should be approached as a developing hierarchical structure that acquires the ability to orient attention to the most significant features in the environment. The development of this system could be described by a series of implicit theories that share a common structure which provides continuity over theory change. According to this view, the early stages which have a fundamental role for the development of mindreading would be described by low-level theories, but as infants become increasingly efficient in predicting behavior of observed agents the higher-order entities become prioritized due to their relevance. Infants thus gradually develop the ability to predict the behavior of others in situations involving attribution of mental states. I propose a strategy based on the analysis of attention deployment that could help to decide which of the alternative theories provides the most adequate account of the mentalizing system at a certain developmental stage. I also suggest that computational modeling could contribute to the research in this area. Simulations of looking behavior based on different ontologies could prove to be useful for choosing the most adequate theory as well as for advancing the understanding of mechanisms involved in the development of theory of mind.
