EEG AS A PREDICTOR OF ANTISOCIAL BEHAVIOR

Slowing of alpha brain activity has been reported among antisocial individuals. One popular hypothesis to explain this slowing assumes a developmental lag, that is, brain immaturity. Studies to date have not established whether the brain wave activity precedes the development of antisocial behavior. The present longitudinal study attempts to answer this question by looking at EEG brain activity measures taken before the beginning of delinquent activity. Slower alpha patterns proved to be characteristic of later delinquents. The findings, however, do not support the developmental immaturity hypothesis.     

HEART RATE AND ANTISOCIAL BEHAVIOR: THE MEDIATING ROLE OF IMPULSIVE SENSATION SEEKING

Although a low resting heart rate is considered the best‐replicated biological correlate of antisocial behavior, the mechanism underlying this relationship remains largely unknown. Sensation‐seeking and fearlessness theories have been proposed to explain this relationship, although little empirical research has been conducted to test these theories. This study addressed this limitation by examining the relationship between heart rate and antisocial behavior in a community sample of 335 adolescent boys. Heart rate was measured during a series of cognitive, stress, and rest tasks. Participants also completed self‐report measures of state fear, impulsive sensation seeking, and both aggressive and nonaggressive forms of antisocial behavior. As expected, increased levels of aggression and nonviolent delinquency were associated with a low heart rate. Impulsive sensation seeking, but not fearlessness, significantly mediated the association between heart rate and aggression. This study is the first to show that impulsive sensation seeking partly underlies the relationship between aggression and heart rate, and it is one of the few to examine the mechanism of action linking heart rate to antisocial behavior. Findings at a theoretical level highlight the role of impulsive sensation seeking in understanding antisocial behavior and at an intervention level suggest it as a potential target for behavioral change.     

A TEST OF LATENT TRAIT VERSUS LIFECOURSE PERSPECTIVES ON THE STABILITY OF ADOLESCENT ANTISOCIAL BEHAVIOR*

Latent trait and life-course theories provide contrasting interpretations of the well-established finding that childhood antisocial behavior often precedes adolescent conduct problems and adult crime. Longitudinal data from 179 boys and their parents were used to test hypotheses derived from the two theoretical perspectives. The findings largely supported the life-course view. Oppositional behavior during late childhood predicted reductions in quality of parenting and school commitment and increased affiliation with deviant peers. These changes, in turn, predicted conduct problems during early adolescence. Although there was a moderately strong bivariate correlation between childhood antisocial behavior and adolescent conduct problems, there was no longer an association between these constructs when the effects of parenting, school, and peers were taken into account. Further, there was evidence that improved parenting, increased school commitment, or reduced affiliation with deviant peers lowered the probability that boys who were oppositional during childhood would graduate to delinquency and drug use during adolescence. Together, these findings suggest that the correlation between childhood and adolescent deviant behavior reflects a developmental process rather than a latent antisocial trait.     

A CROSS‐CULTURAL EXAMINATION OF THE LINK BETWEEN CORPORAL PUNISHMENT AND ADOLESCENT ANTISOCIAL BEHAVIOR*

Several studies with older children have reported a positive relationship between parental use of corporal punishment and child conduct problems. This has lead some social scientists to conclude that physical discipline fosters antisocial behavior. In an attempt to avoid the methodological difficulties that have plagued past research on this issue, the present study used a proportional measure of corporal punishment, controlled for earlier behavior problems and other dimensions of parenting, and tested for interaction and curvilinear effects. The analyses were performed using a sample of Iowa families that displayed moderate use of corporal punishment and a Taiwanese sample that demonstrated more frequent and severe use of physical discipline, especially by fathers. For both samples, level of parental warmth/control (i.e., support, monitoring, and inductive reasoning) was the strongest predictor of adolescent conduct problems. There was little evidence of a relationship between corporal punishment and conduct problems for the Iowa sample. For the Taiwanese families, corporal punishment was unrelated to conduct problems when mothers were high on warmth/control, but positively associated with conduct problems when they were low on warmtwcontrol, An interaction between corporal punishment and warmth/Wcontro1 was found for Taiwanese fathers as well. For these fathers, there was also evidence of a curvilinear relationship, with the association between corporal punishment and conduct problems becoming much stronger at extreme levels of corporal punishment. Overall, the results are consistent with the hypothesis that it is when parents engage in severe forms of corporal punishment, or administer physical discipline in the absence of parental warmth and involvement, that children feel angry and unjustly treated, defy parental authority, and engage in antisocial behavior.     

INDIVIDUAL STABILITY OF ANTISOCIAL BEHAVIOR FROM CHILDHOOD TO ADULTHOOD: TESTING THE STABILITY POSTULATE OF MOFFITT'S DEVELOPMENTAL THEORY*

This paper presents a test of Moffitt's (1993) prediction on the stability of longitudinal antisocial behavior, using data from the South‐Holland Study. Aggressive (overt) and non‐aggressive antisocial (covert) behaviors were measured when subjects were 6–11 years old, and at follow‐ups when they were 12–17 years old and 20–25 years old. In accordance with the postulate, we did find a higher level of stability of overt behavior from childhood to adulthood, compared with childhood to adolescence, especially in combination with early manifestations of status violations and/or covert behavior in childhood. Results related to the stability of covert behavior were not in accordance with the prediction, but did support the recently proposed adjustment to the starting age of the adult phase.     

GENETIC AND ENVIRONMENTAL COMPONENTS OF ANTISOCIAL BEHAVIOR: A STUDY OF 265 TWIN PAIRS*

This study investigates the common-family environmental (CE), within-family environmental (WE), and hereditary (H) components of antisocial behavior and its correlates using a twin study design. The subjects are 265 adolescent twin pairs who reported in a mail survey on their antisocial behavior, deceitfulness, parental rejection (as perceived), anger, impulsivity, and value placed on school achievement. These six variables are intercorrelated in two ways: between-families (twin pairs' sums) and within-families (twin pairs' differences). The former covariance structure captures the twins' resemblances: the latter, the twins' differences in behavior. LISREL is used to model the observed relationships using structural equations containing CE, WE, and H factors. The best-fitting model requires only H and WE factors to explain the variables' relationships. Within this population, delinquent behavior is unaffected by CE influences such as social class, child rearing styles, parental attitudes, parental religion, and other factors equally affecting the twins. The principal genetic correlates of delinquency appear to be deceitfullness and temperamental traits.     

PSYCHOLOGICAL,NEUROPSYCHOLOGICAL AND PHYSIOLOGICAL CORRELATES OF SERIOUS ANTISOCIAL BEHAVIOR IN ADOLESCENCE: THE ROLE OF SELF‐CONTROL*

Gottfredson and Hirschi claim that self‐control is the only enduring personal characteristic implicated in criminal activity. Other scholars, such as Moffitt and Rowe, claim that although self‐control is important, so are neuropsychological and physiological factors. This study attempts to adjudicate between these two positions by examining the ways in which neuropsychological factors, especially those relevant to executive function, biological factors, especially those relevant to autonomic reactivity, and self‐control interrelate to distinguish between offenders and nonoffenders. Data were obtained from adolescents attending public high schools in northern California and adolescents incarcerated in the California Youth Authority. Serious juvenile offenders evince lower resting heart rate, show poorer performance on tasks that activate cognitive functions mediated by the prefrontal cortex, especially those measuring spatial working memory, and score lower on measures of self‐control. Regression analyses indicated that although variations in self‐control distinguish between the two groups, so too do neuropsychological and biological factors, a result that both supports and refutes Gottfredson and Hirschi's contention. In contrast, variation in minor delinquency among high school students is unrelated to frontal lobe functioning and heart rate, but related to variations in self‐control.     

UNPACKING THE RELATIONSHIP BETWEEN ADOLESCENT EMPLOYMENT AND ANTISOCIAL BEHAVIOR: A MATCHED SAMPLES COMPARISON*

A large body of research has consistently found that intensive employment during the school year is associated with heightened antisocial behavior. These findings have been influential in prompting policy recommendations to establish stricter limits on the number of hours that students can work during the school year. We reexamine the linkage between first‐time work at age 16 during the school year and problem behaviors. Our analysis uses group‐based trajectory modeling to stratify youths based on their developmental history of crime and substance abuse. This stratification serves to control for preexisting differences between workers and nonworkers and permits us to examine whether the effect of work on problem behaviors depends on the developmental history of those behaviors. Contrary to most prior research we find no overall effect of working on either criminal behavior or substance abuse. However, we do find some indication that work may have a salutary effect on these behaviors for some individuals who had followed trajectories of heightened criminal activity or substance abuse prior to their working for the first time.     

ANTISOCIAL BEHAVIOR AND YOUTH GANG MEMBERSHIP: SELECTION AND SOCIALIZATION

We examine whether gang membership is associated with higher levels of delinquency because boys predisposed to delinquent activity are more likely than others to join. We use 10 years of longitudinal data from 858 participants of the Pittsburgh Youth Study to identify periods before, during and after gang membership. We build on prior research by controlling for ages and calendar time, by better accounting for gang memberships that occurred before the study began, and by using fixed effects statistical models. We find more evidence than has been found in prior studies that boys who join gangs are more delinquent before entering the gang than those who do not join. Even with such selective differences, however, we replicate research showing that drug selling, drug use, violent behaviors and vandalism of property increase significantly when a youth joins a gang. The delinquency of peers appears to be one mechanism of socialization. These findings are clearest in youth self-reports, but are also evident in reports from parents and teachers on boys' behavior and delinquency. Once we adjust for time trends, we find that the increase in delinquency is temporary, that delinquency falls to pre-gang levels when boys leave gangs.     

STABILITY AND CHANGE IN ANTISOCIAL BEHAVIOR: THE TRANSITION FROM ADOLESCENCE TO EARLY ADULTHOOD*

This longitudinal research, based on two samples of respondents who were differentially involved in delinquency as teenagers, identifies latent trait and life‐course correlates of the persistence of antisocial behavior into young adulthood. The data show that prior delinquency is a stable predictor among respondents in both our household and institutional samples. However, although social bonding has a substantial impact on continued criminality among the household respondents, its influence is minimal among those who were previously institutionalized. The data suggest that the bonding levels and antisocial behavior of serious offenders are more resistant to change than are those of more typical and less serious offenders.     

ON THE RELATIONSHIP BETWEEN FAMILY STRUCTURE AND ANTISOCIAL BEHAVIOR: PARENTAL COHABITATION AND BLENDED HOUSEHOLDS*

In the last several decades, the American family has undergone considerable change, with less than half of all adolescents residing with two married biological parents. Using the National Longitudinal Survey of Youth 1997, we construct an elaborate measure of family structure and find considerable heterogeneity in the risk of antisocial and delinquent behavior among groups of youth who reside in what are traditionally dichotomized as intact and nonintact families. In particular, we find that youth in “intact” families differ in important ways depending on whether the two biological parents are married or cohabiting and on whether they have children from a previous relationship. In addition, we find that youth who reside with a single biological parent who cohabits with a nonbiological partner exhibit an unusually high rate of antisocial behavior, especially if the custodial parent is the biological father.     

NEUROPSYCHOLOGICAL MEASURES OF EXECUTIVE FUNCTION AND ANTISOCIAL BEHAVIOR: A META‐ANALYSIS*

A meta‐analysis was performed to quantify the association between antisocial behavior (ASB) and performance on neuropsychological executive functioning (EF) measures. This meta‐analysis built on Morgan and Lilienfeld's (2000) meta‐analysis of the same topic by including recently published studies and by examining a wider range of EF measures. A total of 126 studies involving 14,786 participants were included in the analyses. Antisocial groups performed significantly worse on measures of EF compared with controls, with a grand mean effect size of d= .44. Significant variation occurred in the magnitude of effect sizes calculated across studies. The largest effect sizes were found for criminality (d= .61) and externalizing behavior disorder (d= .54) ASB groups, whereas the smallest effect sizes were found for antisocial personality disorder (d= .19) groups. Larger differences in EF performance were observed across studies involving participants from correctional settings and with comorbid attention deficit and hyperactivity problems. Overall, the results indicated that a robust association exists between ASB and poor EF that held across studies with varied methodological approaches. The methodological issues in the research literature and the implications of the meta‐analysis results are discussed, and the directions for future research are proposed.     

IS AGE IMPORTANT? TESTING A GENERAL VERSUS A DEVELOPMENTAL THEORY OF ANTISOCIAL BEHAVIOR*

We tested competing hypotheses derived from Gottfredson and Hirschis (1990) general theory and Moffitt's (1993a) developmental theory of antisocial behavior. The developmental theory argues that different factors give rise to antisocial behavior at different points in the life course. In contrast, the general theory maintains that the factor underlying antisocial behavior (i.e., criminal propensity) is the same at all ages. To test these competing predictions, we used longitudinal data spanning from age 5 to age 18 for the male subjects in the Dunedin Multidisciplinary Health and Development Study. Using reports from three sources (parents, teachers, and the boys themselves), we estimated second-order confirmatory factor models of antisocial behavior. These models provided consistent support for the developmental theory, showing that separate latent factors underlie childhood and adolescent antisocial behavior. Moreover, we found that these childhood and adolescent factors related in ways predicted by Moffitt's developmental theory to four correlates of antisocial behavior: Childhood antisocial behavior was related more strongly than adolescent antisocial behavior to low verbal ability, by per activity, and negative/impulsive personality, whereas adolescent antisocial behavior was related more strongly than childhood antisocial behavior to peer delinquency. The two underlying latent factors also showed the predicted differential relations to later criminal convictions: Childhood antisocial behavior was significantly more strongly associated with convictions for violence, while adolescent antisocial behavior was significantly more strongly associated with convictions for nonviolent offenses.     

THE INTERACTION OF ANTISOCIAL PROPENSITY AND LIFE‐COURSE VARYING PREDICTORS OF DELINQUENT BEHAVIOR: DIFFERENCES BY METHOD OF ESTIMATION AND IMPLICATIONS FOR THEORY*

Recent criminological research has explored the extent to which stable propensity and life‐course perspectives may be integrated to provide a more comprehensive explanation of variation in individual criminal offending. One line of these integrative efforts focuses on the ways that stable individual characteristics may interact with, or modify, the effects of life‐course varying social factors. Given their consistency with the long‐standing view that person–environment interactions contribute to variation in human social behavior, these theoretical integration attempts have great intuitive appeal. However, a review of past criminological research suggests that conceptual and empirical complexities have, so far, somewhat dampened the development of a coherent theoretical understanding of the nature of interaction effects between stable individual antisocial propensity and time‐varying social variables. In this study, we outline and empirically assess several of the sometimes conflicting hypotheses regarding the ways that antisocial propensity moderates the influence of time‐varying social factors on delinquent offending. Unlike some prior studies, however, we explicitly measure the interactive effects of stable antisocial propensity and time‐varying measures of selected social variables on changes in delinquent offending. In addition, drawing on recent research that suggests that the relative ubiquity of interaction effects in past studies may be partly from the poorly suited application of linear statistical models to delinquency data, we alternatively test our interaction hypotheses using least‐squares and tobit estimation frameworks. Our findings suggest that method of estimation matters, with interaction effects appearing readily in the former but not in the latter. The implications of these findings for future conceptual and empirical work on stable propensity/time‐varying social variable interaction effects are discussed.     

STRUCTURAL MODELS OF PERSONALITY AND THEIR RELATION TO ANTISOCIAL BEHAVIOR: A META‐ANALYTIC REVIEW*

The authors argue that the concept of personality has much to offer the field of criminology. To this end, they used meta‐analytic techniques to examine the relations between antisocial behavior defined relatively broadly and four structural models of personality: Eysenck's PEN model, Tellegen's three‐factor model, Costa and McCrae's five‐factor model (FFM), and Cloninger's seven‐factor temperament and character model. A comprehensive review of the literature yielded 59 studies that provided relevant information. Eight of the dimensions bore moderate relations to antisocial behavior; the dimensions could all be understood as measures of either Agreeableness or Conscientiousness from the FFM. The implications of these findings for future research are considered.     

EXPLORING THE INTERSEXUAL NATURE OF VIOLENT CRIMES*

Data on criminal homicides (from the Uniform Crime Reports) and aggravated assaults and simple assaults (from the National Crime Surveys) are analyzed to determine the extent to which violent crimes occur within or between sexes. The routine activities approach is used to develop hypotheses, and those hypotheses are tested using models that estimate the proportion of ingroup and outgroup crimes “expected.” With the exception of homicides, in which women murder men more often than expected, each of these violent crimes occurs within sexes more often than expected. There is a strong relationship between the type of violence (simple assault, aggravated assault, and homicide) and the extent to which the target of female aggression is a male.
