Guilt and self-concept in ‘secondary psychopaths’

Thirty-two male and 25 female ‘secondary psychopaths’ and 24 male and 24 female ‘normal’ subjects filled in semantic differential scales relating to the concepts: Myself as I am, Myself when I lie, Myself if I were to steal, Myself as I would like to be, People who lie and People who steal. The Mosher Morality-Conscience Guilt scale and the Eysenck Personality Inventories were also administered. The psychopaths exhibited significantly higher Guilt scores than the normal subjects and had very poor self-image which was reflected in a constant feeling of guilt, regardless of whether or not they were rating transgression. Normal subjects, on the other hand, only rated themselves as feeling guilty when they violated acceptable norms. The findings suggest that guilt in ‘secondary psychopaths’ is partly related to their high level of trait anxiety and partly to their poor self-concept which may be a reflection of their disturbed family background and the constant disapproval that their behaviour creates. Since guilt in the psychopaths did not markedly increase with transgression it is argued that this may explain why guilt fails to inhibit unacceptable behaviour in some psychopaths.     

Authorities’ knowledge of shared group membership and its effects on the respect-informing properties of procedural fairness

We observe that the voice-leads-to-respect process underlying relational models of procedural fairness is assumed to follow primarily if not solely from interaction with an in-group authority. Moreover, if the voice recipients believe that the authority is unaware of this shared group membership, then the provision of voice actually says nothing (to the voice recipients) about their standing as group members; the respect-providing information as valued in-group members is absent because the recipients know that the authority does not know of their shared group membership. We tested these assumptions in a three-way design manipulating the group membership of the authority (in-group vs. out-group), the nature of voice (provided vs. denied) and the nature of group membership knowledge (the authority knows or does not know the voice recipient’s group membership). A significant three-way interaction was found, as predicted, on respect and fairness ratings. These data provide clear experimental support for an unstated, and yet untested, assumption of relational models of procedural fairness.     

Electrodermal indices in a selected prison sample and students

Electrodermal indices relevant to Eysenck's (1970) theory of criminology and subsequent modifications of this theory were compared in a prison sample selected for ‘good’ home backgrounds and a student sample. A previously developed differential electrodermal conditioning paradigm of social learning was administered to both samples.Selected prisoners displayed significantly less evidence of differential responding throughout the extinction phase (p < 0.01), significantly longer half time recovery (p < 0.01) and significantly less stimulus specific responding in extinction (p < 0.01). Spontaneous fluctuations did not differentiate the samples.Results are discussed with reference to personality measures taken concurrently and it is suggested that significant differences between the samples are comparable to previously reported differences between primary psychopaths and non-psychopaths.     

Disturbed prefrontal and temporal brain function during emotion and cognition interaction in criminal psychopathy

Impaired emotional responsiveness has been revealed as a hallmark of psychopathy. In spite of an increasing database on emotion processing, studies on cognitive function and in particular on the impact of emotion on cognition in psychopathy are rare. We used pictures from the International Affective Picture Set (IAPS) and a Simon Paradigm to address emotion-cognition interaction while functional and structural imaging data were obtained in 12 healthy controls and 10 psychopaths. We found an impaired emotion-cognition interaction in psychopaths that correlated with a changed prefrontal and temporal brain activation. With regard to the temporal cortex, it is shown that structure and function of the right superior temporal gyrus is disturbed in psychopathy, supporting a neurobiological approach to psychopathy, in which structure and function of the right STG may be important.     

A preliminary study of Hare's “Research Scale for the Assessment of Psychopathy” in mentally-abnormal offenders

The abbreviated (15-item) version of Hare's Research Scale for the Assessment of Psychopathy (RSAP) was investigated in a sample of male admissions to Broadmoor Special Hospital (N = 50), along with five MMPI measures relevant to psychopathy (Impulsivity, Sociability, Psychopathic Deviate, Anxiety and Sociopathy). Patients were assigned to one of four clinical diagnostic groups: Personality Disorder, Mixed (personality disorder with schizophrenia), Schizophrenia and Affective Disorder. Results indicated that while both psychopathic groups (Mixed and Personality Disorder) showed high scores on almost all RSAP items, the Affective Disorder group showed low scores on almost all items. Results of a discriminant function analysis indicated that Hare's RSAP was superior to the MMPI measures at discriminating between psychopaths and non-psychopaths. Use of the discriminant function to re-allocate patients to criterion groups showed a high hit rate (94%) for psychopathic patients but a hit rate of only 61% for non-psychopathic patients. Half of the schizophrenic patients were mis-allocated to the psychopathic group. The results support the idea of an affective deficit common to psychopaths and schizophrenics, but suggest that psychopaths additionally show a deficit which may be characterized by a lack of goal-directed behaviour.     

Autonomic stress reactivity and executive functions in successful and unsuccessful criminal psychopaths from the community

A significant gap in the psychopathy literature is the lack of studies comparing "successful," nonconvicted psychopaths with "unsuccessful," convicted psychopaths. This study tested the hypothesis that successful psychopaths show increased autonomic stress reactivity and better neuropsychological function compared with unsuccessful psychopaths. A total of 26 controls, 16 unsuccessful psychopaths, and 13 successful psychopaths were assessed on psychophysiological measures recorded during an emotional manipulation, the Wisconsin Card Sorting Test (WCST), Wechsler Memory Scale--Revised subtests, and childhood stressors. Compared with controls, unsuccessful psychopaths showed reduced cardiovascular stress reactivity. In contrast, successful psychopaths showed heightened reactivity, better WCST performance, and more parental absence than unsuccessful psychopaths and controls. The implications of these findings and the generalizability of existing psychopathy research are discussed.     

Assessment of cognitive control in psychopathic and normal prisoners

It has been suggested that psychopaths exhibit specific deficits in cognitive processes associated with frontal lobe functioning. There is also evidence which indicates that level of intelligence may influence expression of impulse control among psychopaths. The present study investigated these hypotheses by comparing groups of 44 psychopaths and 14 normal controls selected from a sample of incarcerated male felons using Minnesota Multiphasic Personality Inventory (MMPI)-defined criteria. Dependent variables included several measures of cognitive flexibility, perseveration, and impulsiveness. Compared to normal controls, psychopaths showed no greater tendencies to persist in incorrect responding, disregard cues suggesting the need to modify behaviors, or proceed impulsively in problem solving. Level of intelligence was found to be a moderator variable influencing performance for psychopaths and normal controls. Results suggest that deficits in cognitive functioning are not necessarily characteristic of psychopaths across situations.     

Psychopathy,anxiety and malingering

Psychopathy is commonly measured as a low score on an Anxiety scale or as a high score on the MMPI Pd scale. The Pd scale, the Spielberger et al. Trait Anxiety scale and a short Achievement Motivation scale were administered to a random postal sample of 115 Australians. It was found that there was a high positive correlation between the Pd and Anxiety scales. This strongly supports Eysenck's theory that psychopaths are neurotic extraverts. A possible alternative explanation of the findings, however, is that the Pd scale may measure not psychopathy but malingering.     

P3 event-related potentials and childhood maltreatment in successful and unsuccessful psychopaths

Although P3 event-related potential abnormalities have been found in psychopathic individuals, it is unknown whether successful (uncaught) psychopaths and unsuccessful (caught) psychopaths show similar deficits. In this study, P3 amplitude and latency were assessed from a community sample of 121 male adults using an auditory three-stimulus oddball task. Psychopathy was assessed using the Psychopathy Checklist-Revised (Hare, 2003) while childhood physical maltreatment was assessed using the Conflict Tactic Scale (Straus, 1979). Results revealed that compared to normal controls, unsuccessful psychopaths showed reduced parietal P3 amplitudes to target stimuli and reported experienced more physical abuse in childhood. In contrast, successful psychopaths exhibited larger parietal P3 amplitude and shorter frontal P3 latency to irrelevant nontarget stimuli than unsuccessful psychopaths. This is the first report of electrophysiological processing differences between successful and unsuccessful psychopaths, possibly indicating neurocognitive and psychosocial distinctions between these two subtypes of psychopathy.     

When two become one: Temporally dynamic integration of the face and voice

In everyday interactions with others, people have to deal with the sight of a face and sound of a voice at the same time. How the perceptual system brings this information together over hundreds of milliseconds to perceive others remains unclear. In 2 studies, we investigated how facial and vocal cues are integrated during real-time social categorization by recording participants' hand movements (via the streaming x, y coordinates of the computer mouse) en route to “male” and “female” responses on the screen. Participants were presented with male and female faces that were accompanied by a same-sex voice morphed to be either sex-typical (e.g., masculinized male voice) or sex-atypical (i.e., feminized male voice). Before settling into ultimate sex categorizations of the face, the simultaneous processing of a sex-atypical voice led the hand to be continuously attracted to the opposite sex-category response across construal. This is evidence that ongoing results from voice perception continuously influence face perception across processing. Thus, social categorization involves dynamic updates of gradual integration of the face and voice.     

Psychopathy and internalism

Do psychopaths make moral judgments but lack motivation? Or are psychopaths’ judgments are not genuinely moral? Both sides of this debate seem to assume either externalist or internalist criteria for the presence of moral judgment. However, if moral judgment is a natural kind, we can arrive at a theory-neutral criterion for moral judgment. A leading naturalistic criterion suggests that psychopaths have an impaired capacity for moral judgment; the capacity is neither fully present nor fully absent. Psychopaths are therefore not counterexamples to internalism. Nonetheless, internalism is empirically problematic because it is unable to explain psychopaths’ moral deficits.     

Reward dominance and passive avoidance learning in adolescent psychopaths

This study tests predictions that adolescent psychopaths are hyperresponsive to rewards (Quay, 1988) and deficient in passive avoidance learning (Newman & Kosson, 1986). Forty male adolescent juvenile offenders were divided into psychopaths and nonpsychopaths using cluster analysis. Subjects were administered a passive avoidance learning task which required learning when to respond to cards associated with either reward or punishment. Results showed a greater responsivity to reward in psychopaths, with no group differences in passive avoidance errors. Results lend support to the view that psychopaths tend to focus on the prospect of reward under conditions of mixed incentives and, when sufficiently motivated, are capable of improved performance. Together with findings of recent psychophysiological studies, these results suggest that adolescent psychopaths may have latent abilities which could have treatment implications.The authors are greatly indebted to the boys and staff of the testing institution for their kind cooperation in this study. Thanks are also due to Dr. Rand Wilcox for statistical consultation and Cheryl Eurton and Marni Ayers for assistance in data coding.     

The Dark Triad of personality: Narcissism, Machiavellianism, and psychopathy

Of the offensive yet non-pathological personalities in the literature, three are especially prominent: Machiavellianism, subclinical narcissism, and subclinical psychopathy. We evaluated the recent contention that, in normal samples, this ‘Dark Triad’ of constructs are one and the same. In a sample of 245 students, we measured the three constructs with standard measures and examined a variety of laboratory and self-report correlates. The measures were moderately inter-correlated, but certainly were not equivalent. Their only common Big Five correlate was disagreeableness. Subclinical psychopaths were distinguished by low neuroticism; Machiavellians, and psychopaths were low in conscientiousness; narcissism showed small positive associations with cognitive ability. Narcissists and, to a lesser extent, psychopaths exhibited self-enhancement on two objectively scored indexes. We conclude that the Dark Triad of personalities, as currently measured, are overlapping but distinct constructs.     

Psychoticism and arousal: Possible evidence for a linkage of p and psychopathy

A study is described in which two postural conditions (standing, reclining) were used to induced high and low activation levels in normal Ss divided into high and low P groups ( (HP and LP). Electrodermal and heart rate (HR) measures were recorded during each of these activation conditions which included instructions, an initial rest period, a series of tones, a rtwo-flash threshold task and a final rest period. It was found that HP Ss tended to display significantly lower automatic arousability and poorer two-flash performance while undergoing the low activation (Recline) condition. There was a reliable tendency for HP Ss to evidence significantly slower recovery and rise times and to manifest significantly lower response criterion and sensory sensitivity. They also manifested a near significantly lower mean HR than LP Ss. The performance of HP and LP groups was compared to findings reported previously for schizophrenics and psychopaths for these tasks. It was posited that the performance of the HP Ss suggests that psychoticism may be more nearly akin to psychopathy than to schizophrenia.     

Responsible Psychopaths Revisited

This paper updates, modifies, and extends an account of psychopaths’ responsibility and blameworthiness that depends on behavioral control rather than moral knowledge. Philosophers mainly focus on whether psychopaths can be said to grasp moral rules (or reasons, or demands) as such, whereas it seems to be important to their blameworthiness that typical psychopaths are hampered by impulsivity and other barriers to exercising self-control. I begin by discussing an atypical case, for contrast, of a young man who was diagnosed as a psychopath at one point but who lacks the element of impulsivity. He exhibits the usual deficits of empathy and related moral emotions, but by now he has developed effective alternative means of conforming to moral rules, essentially on the basis of self-interest. I think it does seem reasonable to hold him morally responsible if he should violate a rule, despite his refusal to acknowledge any specifically moral reasons. I then turn to more typical cases, arguing that blameworthiness is mitigated by the difficulty of learning alternative means of self-control. In a departure from my earlier work, I do not take responsibility to have degrees. But since both blameworthiness and freedom to do otherwise have degrees that depend on the same factors, I go on to explain how it can be reasonable to blame a typical psychopath for an act he may not have been free to avoid. More generally, my suggestion is that notions commonly conflated in philosophers’ treatments of responsibility should be prized apart.     

Recognition of facial expressions of emotions in criminal and non-criminal psychopaths: Valence-specific hypothesis

IntroductionPsychopaths with the dominant reduced interpersonal and affective ability are characterized by the hypofunction of the right hemisphere, while psychopaths with the dominant impulsivity and antisocial behavior are characterized by the hyperfunction of the left hemisphere. The assumption is that this interhemispheric imbalance in a psychopath will also be reflected in the recognition of facial emotional expressions.ObjectiveThe objective is to examine the lateralization of facial expressions of positive and negative emotions as well as processing of facial expressions of emotions in criminal and non-criminal psychopaths.Participants48 male participants age 24–40 were voluntarily recruited from the psychiatric hospital in Nis, Serbia.Stimuli48 black-and-white photographs in two separate tasks were used for the stimulation with central and lateral exposition.ResultsCriminality is related to the reduced recognition of facial expression of surprise and not necessarily to psychopathy, whereas reduced recognition of facial expression of fear is related to psychopathy, but not criminality. Valence-specific hypothesis has not been confirmed for positive and negative emotions in criminal and non-criminal psychopaths and non-psychopaths, but it was shown that positive emotions are equally well processed in both hemispheres, whereas negative emotions are more successfully processed in the left hemisphere.     

Social Anxiety is Associated with a Negatively Distorted Perception of One's Own Voice

According to cognitive models of social anxiety, negatively distorted self-images have a central role in the development and maintenance of social anxiety. In the present study, the relationship between social anxiety and the perception of one's own voice was investigated in a sample of 17 undergraduate students. The participants were asked to recount a story aloud in front of a tape recorder, and then to rate their voice characteristics on a Voice Evaluation Questionnaire. Independent observers (speech therapy students) were then asked to listen to the tape recordings and to rate the participants' voice characteristics on an equivalent version of the Voice Evaluation Questionnaire. Two hypotheses were contrasted: a skill deficits hypothesis and a cognitive distortion hypothesis. The results supported the cognitive distortion hypothesis. A high level of social performance anxiety was associated with an underestimation of one's voice qualities, compared with the independent observers. It is suggested that sound-tape feedback with cognitive preparation should be tested as a method for correcting the negatively distorted voice perception that is associated with social anxiety.     

The nature and dynamics of sexual homicide: An integrative review

The author reviews the definitions, epidemiology, evolving research, offender, and offense characteristics of sexual homicide, a form of intentional killing that occurs in less than 1% of homicides in the United States. Although the extant research is limited by very few comparative studies, repetitive use of small, nonrandom samples, retrospective data, no prospective studies, and the absence of any predictive statistical analyses, the yield over the past 100 years is impressive. The author advances a clinical typology of sexual murderers. The first group of compulsive sexual murderers leaves behind organized crime scenes and are usually diagnosed with sexual sadism and antisocial/narcissistic personality disorders. They are chronically emotionally detached, often primary psychopaths, are autonomically hyporeactive, and the majority experience no early trauma. The second group of catathymic sexual murderers leave behind disorganized crime scenes and are usually diagnosed with a mood disorder and various personality disorders that may include schizoid and avoidant traits. They are hungry for attachment, only moderately psychopathic, are autonomically hyperreactive, and have a history of physical and/or sexual trauma.     

Two subtypes of psychopathic violent offenders that parallel primary and secondary variants

Although psychopathy usually is treated as a unitary construct, a seminal theory posits that there are 2 variants: Primary psychopathy is underpinned by an inherited affective deficit, whereas secondary psychopathy reflects an acquired affective disturbance. The authors investigated whether psychopathy phenotypically may be disaggregated into such types in a sample of 367 prison inmates convicted of violent crimes. Model-based cluster analysis of the Revised Psychopathy Checklist (PCL-R; R. D. Hare, 2003) and trait anxiety scores in the psychopathic subgroup (n = 123; PCL-R > or = 29) revealed 2 clusters. Relative to primary psychopaths, secondary psychopaths had greater trait anxiety, fewer psychopathic traits, and comparable levels of antisocial behavior. Across validation variables, secondary psychopaths manifested more borderline personality features, poorer interpersonal functioning (e.g., irritability, withdrawal, poor assertiveness), and more symptoms of major mental disorder than primary psychopaths. When compared with the nonpsychopathic subgroup (n = 243), the 2 psychopathic variants manifested a theoretically coherent pattern of differences. Implications for etiological research and violence prevention are discussed.     

The perceived attractiveness and traits of the Dark Triad: Narcissists are perceived as hot,Machiavellians and psychopaths not

The current work investigated how a fictitious opposite-sex narcissist, Machiavellian, and psychopath are perceived in an experimental between subjects-design with three groups (total N = 184). Participants rated personality traits (Big Five and Agency/Communion) and different domains of interpersonal attraction (likeability, attractiveness, friend value, short-term mate value, long-term mate value) of the target persons. While all three target persons were not perceived particularly favorably by participants, the narcissist was consistently perceived more favorably than the Machiavellian and the psychopath who were perceived quite similarly to each other. It is discussed why narcissists may be judged more favorably and Machiavellians and psychopaths converge in people’s lay perceptions.
