Alcohol Use in Adolescent Twins and Affiliation with Substance Using Peers

Affiliation with substance using peers is one of the strongest predictors of adolescent alcohol use. This association is typically interpreted causally: peers who drink incite their friends to drink. This association may be complicated by uncontrolled genetic and environmental confounds because teens with familial predispositions for adolescent substance use may be more likely to select into social networks where drinking is common. We test this alternative hypothesis using a sample of 1,820 twin and sibling pairs, and their same-sex best friends, from three waves of the National Longitudinal Study of Adolescent Health. Across all three waves, peer report of substance use did not influence adolescent alcohol use when genetic and shared environmental predispositions for drinking were considered. The association between alcohol use and peer behavior may be a spurious association attributable to a shared genetic liability to drink alcohol and associate with peers who drink alcohol.     

The mere presence of opposite-sex others on judgments of sexual and romantic desirability: opposite effects for men and women

Men's and women's mate preferences impose on each a unique set of adaptive problems that must be solved when judging the desirability of prospective mates. One potentially revealing source of information about an individual's desirability as a romantic partner is contained in the decisions made by same-sex others. The present studies predicted that men's and women's desirability assessments would be affected in opposite ways when target persons were depicted with members of the target's opposite sex. Study 1 (N = 847) documented that women rated men more desirable when shown surrounded by women than when shown alone or with other men (a desirability enhancement effect). In sharp contrast, men rated women less desirable when shown surrounded by men than when shown alone or with women (a desirability diminution effect) . Study 2 (N = 627) demonstrated similar sexually divergent effects for estimates of the desirability of same-sex competitors.     

Brief functional anlaysis and treatment of elopement in preschoolers with autism

As a result of the impact of functional analysis methodologies in identifying maintaining variables of problem behavior, considerable research has been devoted to tailoring the methodologies to be practical for an outpatient setting. The purpose of this study was (a) to use brief functional analysis (BFA) methodologies to empirically demonstrate the function of elopement exhibited by two preschoolers diagnosed with autism and (b) to develop function‐based interventions derived from the results of the BFA. In phase one, a BFA consisting of 5‐min sessions with multiple repetitions of each condition was conducted with each participant. In phase two, the efficacy of function‐based interventions was assessed using a pairwise design. Both participants' rates of elopement were differentially lower during the implementation of the function‐based intervention relative to baseline. Collectively, these results demonstrated that brief functional methodologies could be applied successfully to the assessment and treatment of elopement. Moreover, the application of BFA and the ensuing treatment in an outpatient setting extend the existing research on functional analysis. Copyright © 2008 John Wiley & Sons, Ltd.     

Anchoring in time estimation

In two experiments, an anchoring account of the misestimation of future task duration was tested. This account states that such misestimation occurs because previous task duration serves as an anchor for predictions, leading to underestimation when a longer task follows a shorter one and overestimation when a shorter task follows a longer one. Before estimating the duration of a focal task, participants selected a figure (anchor) of a longer or shorter duration produced by other participants in previous research on the same task (Experiment 1) or a different task (Experiment 2). In both experiments, misestimation differed according to the relative duration of the anchor to the focal task. Underestimation occurred with the shorter anchor and overestimation occurred with the longer one, suggesting that estimates were distorted in the direction of the anchors. This finding is discussed in relation to the role of prior task experience in moderating this anchoring effect.     

‘The Inner Citadels of the Color Line’: Mapping the Micro‐Ecology of Racial Segregation in Everyday Life Spaces

The role of racial segregation in perpetuating racial prejudice and inequality has been widely investigated by social scientists. Most research has concentrated on the macro‐sociological organization of institutions of residence, education and employment. In this paper, we suggest that such work may be usefully complemented by research that investigates the so‐called ‘micro‐ecology of segregation’ in everyday life spaces – the dynamic, largely informal network of social practices through which individuals maintain racial isolation within settings where members of other race groups are physically co‐present. Developing this argument, we discuss some historical examples of research on the micro‐ecological dimension of race segregation in the United States. We also draw examples from an ongoing program of work on everyday practices of contact and segregation in post‐apartheid South Africa. The paper concludes by exploring some conceptual and methodological implications of treating racial segregation as a micro‐ecological practice.     

Untangling the Links between Narcissism and Self‐esteem: A Theoretical and Empirical Review

The links among narcissism, explicit (deliberate, controllable) self‐esteem, and implicit (automatic, uncontrollable) self‐esteem are unclear despite numerous attempts to illuminate these links. Some investigations suggest that narcissism reflects high explicit self‐esteem that masks low implicit self‐esteem, but other investigations fail to replicate this pattern. Here, we place the ‘mask’ model of narcissism in historical context and review the existing empirical evidence for this model. We then discuss three possible issues that might shed light on the inconsistent findings that have emerged from tests of the mask model. These issues include the unreliability of implicit attitude measures, narcissism's different associations with agentic versus communal self‐views, and distinctions between grandiose and vulnerable narcissism subtypes. We also summarize several alternatives to the mask model of narcissism. Throughout, we offer suggestions for improving the study of narcissism and self‐esteem and point to directions for future research on this topic.     

Delinquenzverläufe jugendlicher Sexualmörder

Sexual homicides by juvenile offenders are statistically rare and until now only a few studies explored this phenomenon. Studies on forensic psychiatric court reports and follow-up data from federal criminal records were used to investigate the delinquency of a sample of 19 juvenile sexual homicide perpetrators from their childhood up to the mean age of 45 years of age. More than the half (58%) committed or attempted sexual assaults prior to the sexual homicide. Seven from 13 who were released from custody (54%) committed sexual or violent reoffences. In a long-time analysis as much favourable as unfavourable developments were found. The results suggest that most of the persons who commit sexual homicides as juveniles already committed sexual offences before and have a high risk of sexual and violent reoffending even a long time after the homicide.     

Treatment readiness in violent offenders: The influence of cognitive factors on engagement in violence programs

Advances in offender rehabilitation theory have led to the development of a clear framework of the factors that need consideration for an offender to be ready for therapy and thus gain maximum benefits. Here, we examine in greater detail the role of cognition in readiness for rehabilitation in violent offenders. We assess how cognitive processes and distortions common in violent offenders may affect and hamper rehabilitation readiness. Methods for remediation of cognitive factors that diminish readiness, including motivational interviewing, are discussed. We conclude that cognitive factors are critical in the assessment of readiness in violent offenders and therapeutic efforts to enhance engagement.
