睾酮素与反社会倾向未成年犯的攻击行为：敌意注意偏向的中介和皮质醇的调节作用

为考察睾酮素与反社会倾向未成年犯攻击行为的关系,在整合攻击行为生物激素视角和社会认知视角的基础上,探究敌意注意偏向的中介作用与皮质醇的调节作用。对84名未成年犯的激素水平、敌意注意偏向以及攻击行为进行调查。结果显示：(1)敌意注意偏向(注意不稳定性、注意回避)在睾酮素对攻击行为的影响中起完全中介作用;(2)皮质醇调节睾酮素与敌意注意偏向的关系,仅在高皮质醇水平下,敌意注意偏向的中介效应显著。基于生物激素影响攻击行为的中介机制和调节机制,可尝试从增加对敌意刺激的注意回避和提高皮质醇水平两个方面对反社会倾向未成年犯的攻击暴力行为进行干预。     

暴力犯罪者对负性情绪信息注意偏向的ERP研究

采用视觉搜索范式,探讨了暴力犯罪者对情绪刺激（愤怒面孔与高兴面孔）的注意偏向特点。行为数据显示,相比非暴力组,暴力组对愤怒面孔的反应要显著快于高兴面孔,初步验证了暴力犯罪者对负性情绪信息存在注意偏向。ERP数据进一步表明,当目标刺激为愤怒面孔时,暴力组N2pc的潜伏期要显著小于非暴力组,说明暴力犯罪者对愤怒面孔的觉察早于高兴面孔,对负性情绪刺激更为敏感。由于N2pc的波幅不存在显著差异,差异主要表现在反应时和潜伏期,说明暴力犯能够更快的觉察到负性情绪面孔,但并没有对其投入更多的注意资源,出现回避模式,表明暴力犯对负性情绪信息的加工是一种警觉—回避模式。     

hate crimes against the Amish: a qualitative analysis of bias motivation using routine activities theory

Research on hate crime has largely been limited to official statistics collected by the Federal Bureau of Investigation and some independent scholarly research of hate crime victims. Few, however, have studied hate crime offenders. Offender narratives of hate crime participation are the focus of this study. Further, few have studied hate crimes against the Amish and their offenders. This study examines hate crime against the Amish with a particular focus on the bias motivation that generates anti-Amish hate crime. To accomplish this task, non-Amish hate crime offenders were enlisted to share their experiences and stories about anti-Amish hate crime. A total of eight subjects were interviewed; the subjects supplied over 16 hours of audiotaped narrative describing acts of "Claping" they had committed against Old Order Amish. The data were transcribed and an analysis of the interview data revealed that themes emerged from offender narratives within each element of routine activities theory. The data support that the subjects were motivated offenders, the Amish were perceived as suitable targets, and there was a perception that guardians were lacking within the community to discourage anti-Amish hate crime. However, it is important to consider the themes that emerged within each dimension of routine activities when applying the theory to anti-Amish bias crime.     

Physical Attractiveness,Dangerousness, and the Canadian Criminal Code1

The Canadian Criminal Code contains provisions for labelling certain convicted criminal offenders as Dangerous Offenders. Sentences of indefinite duration are usually imposed on these offenders in place of the fixed sentences that would normally be imposed. The present study examined one potential source of bias in the use of the Dangerous Offender provisions, the physical attractiveness of an offender. Two hundred and eighty-four adults were given information about a hypothetical offender, including a facial photograph and a conviction record. They responded to questions about the dangerousness of the offender, including questions drawn from the Dangerous Offender criteria. Subjects perceived physically unattractive sexual offenders as significantly more likely to fulfill the Dangerous Offender criteria than average-looking and attractive sexual offenders. In particular, unattractive sexual offenders were seen as significantly less likely to restrain their behavior in the future. In light of the fact that there is currently no evidence that physical attractiveness is a valid predictor of sexual offender recidivism, this finding provides grounds to question whether the Dangerous Offender provisions of the Canadian Criminal Code, as they now stand, can be administered impartially.     

The evaluation of truthfulness in alleged sex offenders' self-reports: 16PF and MMPI validity scales.

The evaluation of response bias (i.e., minimization or exaggeration) is central to forensic psychological evaluations. Yet few studies have assessed forensic samples to investigate the ability of psychological tests to detect response bias. We studied the relationship between the Sixteen Personality Factors Questionnaire (16PF) and the Minnesota Multiphasic Personality Inventory (MMPI) validity scales for 65 alleged sex offenders and assessed the effects of different cutoff scores for the 16PF validity scales. Results indicate consistent significant correlations between the validity scales of the 16PF and the MMPI for measures of minimization and exaggeration. use of a priori cutoff scores resulted in the classification of our sample in proportions parallel to those found in previous research for the 16PF Fake-Good scale but not the Fake-Bad scale. Our results indicate that 16PF validity scales are useful, but interpretations must take into account different base rates of response bias between sex offenders and the general population.     

Racial Attitudes and the Death Penalty1

This study investigated the relationship between overt and subtle forms of racism with Whites' recommendations for capital sentencing of Black and White offenders convicted of murder. White participants (n= 104) viewed 5 other “jurors” (all Whites or 4 Whites and 1 Black) on videotape individually presenting their decisions to vote for the death penalty in the case. It was hypothesized that the bias of high prejudice-scoring participants would be overt, but that the pattern for low prejudice-scoring participants would be more complex. As predicted, among high prejudice-scoring participants, Black defendants received stronger recommendations for the death penalty than did White defendants. Among low prejudice-scoring White participants, Black offenders received stronger recommendations for the death penalty only when a Black juror advocated the death penalty.     

“Coming Clean” on Duty of Care: Australian Print Media’s Representation of Male Versus Female Sex Offenders in Institutional Contexts

Public opinion about sexual abuse of minors is greatly shaped by mass media and the way individual cases are reported. This paper examines Australian print media??s representation of sex offenders, focussing particularly on the sex of the offenders and aiming to shed light on some of the misconceptions and deep-rooted prejudices within the population at large. Given the multi-faceted nature of sexual offences, this paper focuses on sexual offences committed by both males and females against minors in the context of a companion breach of duty of care. In order to explore the effect that linguistic tools can have in the Australian print media??s way of reporting sexual abuse cases, twenty-nine newspaper articles published in Australian dailies were selected for analysis. The analysis of these articles reveals a marked bias in the manner in which sexual offences perpetrated by males, as opposed to females, are reported, suggesting a male monopoly on sexual abuse. We argue that this biased representation, which hinders adequate profiling of sexual offences against minors, may stem from an androcentric view of sexuality and from the systematic denial of female agency when it comes to sex.     

Transforming Potential Offenders into Motivated Ones: Are Sex Offenders Tempted by Alcohol and Pornography?

One of the primary concerns of scholars of routine activity theory is the explication of the three core elements necessary for crime to occur. Using sex offenders as a sample of offenders, the present analysis examines the element potential offender and considers whether or not there are differences among offenders and their locations that may transform potential offenders into actively motivated ones. Until recently, most routine activity scholars took potential offenders as a given and used the terms potential and motivated interchangeably. This analysis shows that there is a distinctive difference between the presence of potential offenders and the idea that there may be offenders who are more actively motivated, particularly by the presence of community temptations (e.g., factors that attract or draw offenders to offending). We find that for sexual victimization rates, the presence of potential offenders is insignificant, whereas the presence of potential offenders in combination with the presence of community temptations is significant.     

Cross-cultural clinical judgment bias in personality disorder diagnosis by forensic psychiatrists in the UK: a case-vignette study

Previous research in the UK has suggested that cross-cultural bias in personality disorder diagnosis might partly account for the smaller proportion of Black, relative to White, patients with personality disorder in secure psychiatric hospitals. Using the case-vignette method, we investigated cross-cultural clinical judgment bias in the diagnosis of personality disorder in African Caribbean men by 220 forensic psychiatrists in the UK. In the vignette describing possible DSM-IV antisocial personality disorder, Caucasians were 2.8 times more likely to be given a diagnosis of personality disorder than African Caribbeans. Diagnosis also varied according to the ethnicity of the clinicians. No cross-cultural bias was found in the vignette describing possible DSM-IV borderline personality disorder. These findings are important in relation to recent policies for offenders and others with personality disorder, and to the current focus on delivering race equality in mental health services in the UK. Ongoing debates about the strengths and limitations of the case-vignette method are also discussed.     

Application of the behavioral investigative support system for profiling perpetrators of serial sexual assaults

The authors developed a data-based profiling system in order to support offender profiling. The system stored incident records of prior offenders. Inputting offence details of an unsolved incident, a probability score was assigned to each prior offender in the system; the score represented the behavioral similarity with the unsolved incident. The system then ranked all offenders in the system according to the probability scores, and prioritized the high-ranked offenders as possible suspects. Moreover, the system inferred the characteristics of unknown offenders by accumulating characteristics of the high-ranked offenders. The system achieved promising accuracy, especially for linking crimes to perpetrators. In 45 out of 81 simulation trials, the target offenders were retrieved as a rank score of 1 from among 868 sex offenders.     

Good things come to those who wait: Time discounting differences between adult offenders and nonoffenders

Criminal behavior has been explained by the idea that offenders have a lack of self-control. Yet, Wilson and Daly reported that juvenile offenders exhibit time-discounting tendencies similar to those of nonoffending juveniles. As no previous study has compared time-discounting behavior of adult offenders with nonoffenders, we raise the question, do adult offenders exhibit shorter time horizons or the tendency to discount future rewards? To answer this question, 89 offenders (ex-prisoners and prisoners) and 106 nonoffenders completed a time-discounting measure containing 27 different monetary choices. Our results show that, counter to findings with juvenile offenders, adult offenders (ex-prisoners) exhibit significantly shorter time horizons and discount more than nonoffenders as delayed payoffs increase to medium and large rewards. Furthermore, both offenders and nonoffenders are less likely to discount as the reward of future gains increases to medium and large.     

Teenage Offenders' Ability to Detect Deception in Their Peers

This study investigated the deception detection abilities of teenage offenders and teenage non‐offenders who made veracity judgments about 12 videotaped interviewees and also explored the behavioural characteristics of teenage liars and truth tellers. The findings revealed that teenage offenders were significantly more accurate in their credibility judgments than teenage non‐offenders. However, the offenders' impressive accuracy rates were not as a consequence of using valid cues to deceit. The feedback hypothesis helps to explain why the offenders were more accurate in their decisions: Operating within a criminal environment may mean that teenage offenders frequently lie and are lied to. Consequently, they receive more feedback than non‐offenders regarding the effectiveness of their lies as well as how successful they are at detecting lies. As a result, their lie detection ability improves. The current study suggests moving away from individual deceptive cues as predictors of deceit towards a more intuitive and holistic approach to lie detection, such as the Brunswikian Lens Model.Copyright © 2016 John Wiley & Sons, Ltd.     

Do criminal offenders specialize in crime types?

A common misconception exists that criminal offenders specialize in types of crime, such as serial murders, domestic violence, and sex offenses. This article explores the research on specialization in general criminal offenders, domestic violence offenders, and sex offenders. This review finds that although there are a few specialists, the majority of criminal offenders are generalists who exhibit wide versatility in offending. The implications for legal and mental health policies are discussed.     

Modified TC for MICA offenders: crime outcomes

The study randomly assigned male inmates with co-occurring serious mental illness and chemical abuse (MICA) disorders to either modified therapeutic community (MTC) or mental health (MH) treatment programs. On their release from prison, MICA inmates who completed the prison MTC program could enter the MTC aftercare program. The results, obtained from an intent-to-treat analysis of all study entries, showed that inmates randomized into the MTC group had significantly lower rates of reincarceration compared with those in the MH group. The results also show that differences between the MTC + aftercare and comparison group across a variety of crime outcomes (i.e. any criminal activity, and alcohol or drug related criminal activity) are consistent and significant, and persist after an examination of various threats to validity (e.g. initial motivation, duration of treatment, exposure to risk). This study provides some support for the effectiveness of the prison TC only condition. The findings are encouraging and consonant with other studies of integrated prison and aftercare TC programs for substance abusing non-MICA offenders, although qualified by the possibility that selection bias (i.e. differences in motivation on entry into aftercare) may be operating. Nevertheless, given the available evidence and the need for effective programming for MICA offenders, program and policy makers should strongly consider developing integrated prison and aftercare modified TC programs for MICA offenders.

Race Shapes Perceptions of Juvenile Offenders in Criminal Court1

We investigated the effects of defendant race, victim race, and juror gender on non‐African American mock jurors' perceptions of crimes committed by juvenile offenders. We predicted that mock jurors, particularly men, would render more pro‐prosecution case judgments when the defendant was African American than White. We also predicted that defendants would be judged more harshly when the crime victim was portrayed as White rather than as African American. Although there were few main effects of defendant race or victim race on case judgments, defendant and victim race by juror gender interactions revealed that men (but not women) demonstrated the predicted bias against African American defendants and victims. Explanations and implications are discussed.     

Comparing serial homicides to single homicides: A study of prevalence,offender, and offence characteristics in Sweden

Multiple and serial homicides constitute around 1.6% of all homicides but have unusually tragic outcomes. The aims of this study were to report the prevalence serial‐homicide offences and the characteristics of serial‐homicide offenders in a non‐North American context. The study included all convicted serial‐homicide offenders in Sweden from 1973 to 2012 (n = 25), as well as a population‐based control sample of single‐homicide offenders collected during 2007 and 2009 (n = 201). Similar to U.S. findings, approximately 1.6% of homicides could be attributed to serial‐homicide offenders. Serial offenders were more often diagnosed with personality disorders and autism‐spectrum disorders compared with single offenders; and serial offences more often involved victims who were female and unacquainted with the offender, as well as planning, sexual motives, and asphyxia as method of violence. One third of serial offences involved actions aimed at disguising the manner of death; such actions were considerably less common in single‐homicide offences. Few offenders displayed the traditional profile of a serial‐homicide offender; however, one third displayed sexual motives, a rate roughly 10 times higher than that in the single‐homicide group. The study concludes that serial‐homicide offenders should be subjected to forensic‐psychiatric examinations and that research involving cross‐contextual differences and similarities in serial‐homicide offenders is needed.     

The Effect of Adolescent Sex Offender Abuse History on Counselor Attitudes

Counseling students' judgments of adolescent sex offenders with sexual or physical abuse histories were examined. Sexually abused offenders were more desirable as prospective clients than were nonabused offenders. Sexually abused counselors desired to see physically abused offenders as clients over sexually abused offenders. Implications for counseling are presented.     

The relation between anger and antisocial beliefs in young offenders

The tendency for youth to report antisocial beliefs has been identified as a major risk factor in delinquency. Advances in emotion research suggest the importance of examining the emotional concomitants of cognitive appraisals such as antisocial beliefs. The present study examined the relation between anger and antisocial beliefs in a sample of young offenders and investigated whether scores on either variable differentiated aggressive from non-aggressive offenders. Twenty-two aggressive and 20 nonaggressive young offenders were compared on two questionnaires measuring anger and antisocial beliefs, respectively. The findings revealed a significant correlation between the two measures. In addition, it was found that the aggressive offenders, compared to their non-aggressive counterparts, scored significantly higher on anger and antisocial beliefs. These findings extended previous research on the characteristics that differentiate aggressive and non-aggressive offenders. Results also support the rationale for incorporating both cognitive and affective components in intervention programs designed for aggressive young offenders.     

Driving aggression in forensic and non‐forensic populations: Relationships to self‐reported levels of aggression,anger and impulsivity

A series of four questionnaires — the Buss‐Perry Aggression Questionnaire (AQ), the Barratt Impulsivity Scale (BIS‐11), the Driving Anger Scale (DAS) and a Driving Violence Inventory (DVI) — were administered to a sample of 473 British drivers consisting of undergraduates (N=185), members of the public (N=106) and offenders (N=182) serving sentences in closed prisons in England (violent=82, non‐violent=100). Offenders consistently rated acts of driving aggression as less severe compared with other drivers. Offender attributions of driving violence differed to other drivers in that they were equally likely to perceive obscene gesturing as high or low intensity responses; they also viewed assault as a high intensity response whereas members of the public rated it more severely. Trait levels of anger and aggression were the predictors of driving violence in all groups but previous aggressive behaviour was only a predictor for the offenders. Gender and age were found to be predictors of aggressive driving in non‐offenders. Even with the effects of age controlled, offenders (and violent offenders in particular) scored higher on measures of driving anger and aggression. These data suggest that offenders differ in their perceptions of aggressive behaviours experienced in everyday driving and as a consequence are more likely to commit acts that other drivers perceive as violent. As offenders are known to display similar perceptual biases in other domains, identified as precursors to their aggressive behaviour, it seems likely that experience effects (as reflected in the trait measures) underpin differences in driving aggression between offenders and non‐offenders.
