国外精神病态罪犯的脑机制研究述评

精神病态是一种个体表现在人际关系、情感、生活方式和反社会特质等方面的人格障碍, 与非精神病态者相比, 精神病态者更容易违反社会规则和法律, 表现出更加残忍和极端的侵犯模式, 犯罪的起始年龄更早, 犯罪活动更为广泛和多样, 累犯率非常高。国外关于精神病态罪犯脑机制的ERP研究表明精神病态罪犯注意朝向、语义和情感加工以及对错误加工的后期阶段存在缺陷。MRI和fMRI的研究表明, 大脑结构异常以及额叶-边缘系统回路活动异常与精神病态行为有关。     

精神病态暴力犯执行功能的缺陷*

为了解精神病态罪犯可能存在的执行功能缺陷及其是否受冲动性影响,研究采用精神病态检核表（PCL-R）筛选出30名精神病态组被试和30名非精神病态组被试,通过爱荷华赌博任务（IGT）和河内塔任务（TOH）对两组被试执行功能的特点进行分析,并结合冲动性量表（BIS-11）对其冲动性进行测量。研究发现精神病态组的冲动性显著高于控制组;精神病态组选择高风险的不利牌显著多于对照组,即对惩罚不敏感;精神病态组在河内塔任务中的错误次数及所消耗时间都显著高于控制组;冲动性水平与两任务得分均无显著相关。结果表明,精神病态暴力犯在与前额叶相关的执行功能上存在缺陷,并与个体的高冲动性无关。     

罪犯精神病态的初步探索

以中国罪犯为被试,对Hare精神病态量表进行修订,并在此基础上进一步探讨罪犯精神病态的影响因素。研究结果表明:(1)修订的Hare精神病态量表具有良好的信度和效度;(2)年龄、文化程度、婚姻状况和犯罪次数是影响罪犯精神病态得分的重要因素。20-29岁年龄组罪犯精神病态的得分显著高于30-38岁年龄组;文化程度高的罪犯精神病态的得分显著低于文化程度低的罪犯,大专以上文化程度的罪犯精神病态得分最低;未婚罪犯精神病态的得分显著高于已婚和离异的罪犯;累犯精神病态的得分显著高于初犯。     

精神病态的家庭风险因素

精神病态(psychopathy)是一种个体表现在人际关系、情感、生活方式和反社会特征等方面的人格障碍, 其特征为自我中心、欺骗、冲动、缺乏共情、缺乏罪恶感等。以往研究偏向于精神病态的生理机制, 认为精神病态具有高度的遗传性, 近期越来越多的研究发现家庭因素对精神病态的重要影响。这些因素包括：产前风险因素、破碎家庭、不良的教养方式、不安全的亲子依恋关系和童年期虐待等。未来的研究应探讨家庭因素对各个精神病态亚型的作用机制, 探索抑制精神病态表达的保护性环境因子, 并构建精神病态的生物心理社会模型等。     

精神控制是一种病态文化现象

邪教是一种普遍的病态社会文化现象。综观世界各国的邪教,其存在的共同基础之一就是有目的、有计划地实施精神控制,不出现精神控制或及时消除了精神控制,邪教就失去了存在的基础。所以,应该实施避免和预防精神控制战略以根治和预防邪教的发生。除了邪教的精神控制,还有其他类型的精神控制,如,准邪教,会道门,巫术迷信,非法传销等。预防精神控制可以收一箭双雕之效。 何谓精神控制     

认知抑制与人际宽恕:特质宽恕的调节作用

采用《特质宽恕量表》测量了102名大学生的特质宽恕能力,并通过Flanker任务和情景回忆法评估了被试的认知抑制和人际宽恕水平,目的是探讨特质宽恕、认知抑制与人际宽恕三者之间的关系。结果发现:(1)认知抑制、特质宽恕与人际宽恕各维度之间存在两两显著相关(除认知抑制与仁慈动机之外);(2)特质宽恕对回避、报复和仁慈动机均具有预测作用,而认知抑制则只对报复动机具有预测作用;(3)特质宽恕与认知抑制对回避动机具有负向的调节作用,对仁慈动机具有正向的调节作用。     

自闭特质对疼痛共情的影响：疼痛负性情绪和认知的中介作用

已有研究提示自闭症个体的疼痛共情缺陷可能源于自身疼痛的异常。鉴于高自闭特质与自闭症的相似性,本研究分别通过实验范式和问卷调查评估了状态和特质共情,旨在刻画自闭特质、自身疼痛与共情之间的联系。在假双人疼痛共情范式中,高自闭特质个体在目睹他人接受疼痛时P2响应更强,不愉悦度评分更高,且部分源于对疼痛的高恐惧水平。问卷调查结果发现,自闭特质水平越高,在共情特质量表的观点采择维度得分越低,而个人痛苦维度得分越高,其中疼痛恐惧和灾难化中介了自闭特质与个人痛苦之间的联系。因此,高自闭特质个体表现出高水平的状态和特质情绪共情,且部分源于对疼痛存在更为负面的情绪和认知。这支持从自身疼痛异常的角度去理解高自闭特质和自闭症群体的共情等社会功能障碍,为临床治疗和干预提供了潜在的靶点。     

个体性与康吉莱姆的生命哲学——读《正常与病态》有感

《正常与病态》一书通过对正常与病态关系的研究,提出病态并不是正常的量变,所谓科学地区分正常与病态的方法是不存在的,只有通过病态才能认识正常,才能认识生命的本质。病态不仅仅具有负性的价值,亦有积极的创造性价值,生命通过病态的创造性价值主动适应变化的环境。从本体论上看,生命个体是一种关系的存在;从认识论上看,生命具有创造性;从价值论上看,生命亦是一种规范性的存在,生命本质即个体性。医学治疗应尊重生命的个体性。     

“病态科学”与科学家

1953年在通用电气公司作报告的时候,诺尔化学奖获得者艾尔文·朗缪尔率先提出“病态科学”的概念。按他的话说,“‘病态科学’是打着科学旗号的非科学。”他当年举的例子有对N射线和基因分裂辐射的发现。1981年,俄勒冈大学心理学教授雷·海曼在美国科学促进会的大会上,作了题为“‘病态科学’及其对治”的报告。海曼认为“病态科学”的定义应该加以扩展,应包括科学家对错误观念和错误理论的顽固坚持,包括作

The Role of Rape Myth Acceptance and Psychopathy in Sexual Assault Perpetration

Perpetrators of sexual aggression consistently report higher scores on measures of psychopathy and acceptance of rape myths relative to nonperpetrators. However, less is known about psychopathy among nonincarcerated individuals and the relation between the two constructs has not been empirically examined among college perpetrators. To address this gap, both constructs were measured in a sample (N?=?308) of college men. Rape myth acceptance was positively correlated with psychopathy, and perpetrators scored higher on both constructs. Myths transferring responsibility to victims were related to Factor 1 psychopathy (i.e., callous and manipulative traits). The myth that “rape is trivial” was associated with Factor 1 and Factor 2 (i.e., impulsive and antisocial behavior), possibly suggesting that this myth is related to a larger tendency to excuse aggressive behavior. Although both constructs distinguished perpetrators when considered individually, rape myth acceptance did not explain unique variance in the presence of psychopathy.     

Validation of the Greek Cypriot Translation of the Triarchic Psychopathy Measure

Psychopathy is conceived of as a pathological constellation of personality traits, manifested in aberrant behavioral, interpersonal, and emotional tendencies. This study examined within a Greek-speaking nonclinical sample (N = 419) associations between differing phenotypic dimensions of psychopathy (boldness, meanness, disinhibition) assessed via the Triarchic Psychopathy Measure (TriPM) and self-report criterion measures of psychopathology, personality, and history of abuse and neglect. Consistent with predictions of the triarchic model of psychopathy, evidence was found for distinct correlates of the 3 phenotypic dimensions. Boldness was associated with both adaptive (immunity to anxiety/distress, fearlessness, low hostility) and maladaptive tendencies (grandiose manipulative traits, Machiavellian features including desire for control/status, and verbal aggression). Meanness was related to callous and unemotional traits, features of Machiavellianism (e.g., amoral manipulation and distrust of others), physical aggression, and absence of positive parenting. Disinhibition, by contrast, was characterized by anxiety and distress, exposure to violence, and retrospective accounts of abuse history, along with impulsive, irresponsible, and hostile tendencies. These findings indicate that the Greek-Cypriot translation of the TriPM effectively assesses the constructs of the triarchic model and extend what we know about their empirical correlates.     

An examination of the Validity of the Elemental Psychopathy Assessment: Relations with Other Psychopathy Measures,Aggression, and Externalizing Behaviors

The Elemental Psychopathy Assessment (EPA) is a new self-report measure of psychopathy designed to assess the personality traits associated with psychopathy from a Five Factor Model perspective. The current study examined the validity of the EPA in sample of undergraduates by examining the relations between the EPA scales and three validated self-report psychopathy instruments, as well as assessments of aggression, substance use, and antisocial behavior. The EPA scales manifested strong convergent validity with the extant psychopathy measures and an expected pattern of relations with measures of externalizing behaviors. Overall, the EPA appears to be a promising measure of psychopathy which provides new opportunities to explore the underlying structure of this construct and parse its relations with constructs central to its nomological network.     

Testing the properties of the triarchic model of psychopathy in a community sample: Self‐reported trait aggression and drug consumption associations

The triarchic model of psychopathy encompasses different conceptions of psychopathic personality characterized by three phenotypic components: boldness, disinhibition, and meanness. Psychopathy is a complex construct at both emotional and behavioral level. The aim of this study was to determine the core elements of psychopathic personality in a community sample and analyze the relation between these elements and other personality traits such as aggression, and certain specific behavioral manifestations such as substance use. The study sample comprised 1,159 participants aged between 17 and 74 years, who were administered the Triarchic Psychopathy Questionnaire, the Impulsive‐Premeditated Aggression Scale, and the Aggression Questionnaire. The results show that the constructs of meanness and disinhibition are more highly associated with different forms of both impulsive and premeditated aggression. Furthermore, men scored higher on all three components of the triarchic model compared to women. Finally, higher substance use (tobacco and drugs) was associated with higher scores in meanness, boldness, and disinhibition. These findings demonstrate the importance of assessing psychopathy in a community sample, and the detection of possible risk factors for the disorder.     

Elucidating the Construct Validity of the Psychopathic Personality Inventory Triarchic Scales

This study sought to replicate and extend Hall and colleagues’ (2014) work on developing and validating scales from the Psychopathic Personality Inventory (PPI) to index the triarchic psychopathy constructs of boldness, meanness, and disinhibition. This study also extended Hall et al.'s initial findings by including the PPI Revised (PPI–R). A community sample (n = 240) weighted toward subclinical psychopathy traits and a male prison sample (n = 160) were used for this study. Results indicated that PPI–Boldness, PPI–Meanness, and PPI–Disinhibition converged with other psychopathy, personality, and behavioral criteria in ways conceptually expected from the perspective of the triarchic psychopathy model, including showing very strong convergent and discriminant validity with their Triarchic Psychopathy Measure counterparts. These findings further enhance the utility of the PPI and PPI–R in measuring these constructs.     

Mapping Gray’s BIS and BAS constructs onto Factor 1 and Factor 2 of Hare’s Psychopathy Checklist – Revised

Reinforcement sensitivity theory (RST; Gray, 1987; Gray & McNaughton, 2000) has proven to be a valuable tool for understanding psychopathy (e.g., Fowles, 1980, 1988; Newman & Malterer, 2009; Poythress et al., 2008). Recent research has linked two RST constructs, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS), to individuals with primary psychopathy and secondary psychopathy (Lykken, 1995; Newman, MacCoon, Vaughn, & Sadeh, 2005): Primary psychopaths manifest low BIS reactivity and secondary psychopaths manifest high BAS reactivity. In the present study, we examine the relationships between the BIS/BAS constructs and Factors 1 and 2 of the Psychopathy Checklist – Revised (PCL-R) in a sample of 472 incarcerated male offenders. Paralleling their relationships with primary and secondary psychopathy, the BIS/BAS constructs were differentially related to the two PCL-R factors. Specifically, the influence of the BIS was found to be more prominent than the influence of the BAS for Factor 1, and the influence of the BAS was more prominent than that of the BIS for Factor 2.

Distinct characteristics of psychopathy relate to different subtypes of aggression

This article both selectively reviews the evidence supporting the view that reactive and proactive aggression actually reflect related but separate constructs, and also investigates the selective relationship between these forms of aggression and psychopathic personality in 121 male prison inmates. Results show that total psychopathy scores were related to residualized scores of proactive (but not reactive) aggression. However, different sub-characteristics of psychopathy were differentially related to reactive as well as proactive aggression. Results support the view that reactive and proactive aggression have differential correlates, and suggest that while psychopathic personality is predominantly characterized by proactive aggression, some psychopathy components are more related to reactive aggression.     

Clarifying the role of defensive reactivity deficits in psychopathy and antisocial personality using startle reflex methodology

Prior research has demonstrated deficits in defensive reactivity (indexed by potentiation of the startle blink reflex) in psychopathic individuals. However, the basis of this association remains unclear, as diagnostic criteria for psychopathy encompass two distinct phenotypic components that may reflect differing neurobiological mechanisms-an affective-interpersonal component and an antisocial deviance component. Likewise, the role of defensive response deficits in antisocial personality disorder (APD), a related but distinct syndrome, remains to be clarified. In the current study, the authors examined affective priming deficits in relation to factors of psychopathy and symptoms of APD using startle reflex methods in 108 adult male prisoners. Deficits in blink reflex potentiation during aversive picture viewing were found in relation to the affective-interpersonal (Factor 1) component of psychopathy, and to a lesser extent in relation to the antisocial deviance (Factor 2) component of psychopathy and symptoms of APD-but only as a function of their overlap with affective-interpersonal features of psychopathy. These findings provide clear evidence that deficits in defensive reactivity are linked specifically to the affective-interpersonal features of psychopathy and not to the antisocial deviance features represented most strongly in APD.
