Emotion Regulation Difficulties and Callous-Unemotional Traits: The Role of Guilt Across Samples of Incarcerated Male Adult Offenders

ABSTRACT The study aimed to: (1) analyze differences between psychopathic and non-psychopathic offenders in terms of difficulties in emotion regulation and callous-unemotional traits, (2) investigate the association between difficulties in emotion regulation and callous-unemotional traits among psychopathic and non-psychopathic offenders, and (3) examine the mediation role of guilt in the relationship between difficulties in emotion regulation and callous-unemotional traits among non-psychopathic offenders, controlling for the level of desirable responses. The participants were 191 incarcerated male adult offenders serving their sentences in closed and semi-open custody. The incarcerated offenders participated in a semi-structured interview and completed self-report measures of emotion dysregulation, guilt, callous-unemotional traits, and social desirability. According to the results on the Hare Psychopathy Checklist-Revised, 60 (27.9%) participants were included in the psychopathic group, while 131 (60.9%) were non-psychopathic. The results showed a positive relationship between difficulties in emotion regulation, callousness, and psychopathy. The multiple regression analysis indicated that guilt contributed to the variance of callousness. Guilt was a mediator in the relationship between difficulties in emotion regulation and callousness among the group of non-psychopathic incarcerated offenders. The current study highlighted the importance of guilt as an adaptive moral emotion useful in the treatment of several psychological problems among male offenders.

Female Psychopathy and Mortality.

The mortality of female psychopaths has scarcely been investigated. To estimate the association between psychopathy and mortality, data from subjects having been in forensic psychiatric assessments at Niuvanniemi Hospital during 1984–1993 were linked to the data from the National Death Registry. Sixteen psychopathic females scoring 25 points or higher in the PCL-R scale (psychopaths) were followed up for a median (IQR) 21 (17–25) years and 41 offenders scoring <25 on the PCL-R (non-psychopathic offenders) for 22 (17–25) years. In both psychopath and non-psychopath offender groups, the mortality was significantly higher (p < 0.01) than in the general population, being over 12-fold among psychopathic and over 6-fold among the non-psychopathic offenders.

So what'cha want? The impact of individualised rewards on associative learning in psychopathic offenders

Psychopathic individuals typically present with associative learning impairments under explicit learning conditions. The present study aimed to investigate whether the formation of stimulus-outcome associations, as well as updating of these associations after changed contingencies, could be improved by using rewards with sufficiently high subjective values. To this end, 20 psychopathic offenders, 17 non-psychopathic offenders and 18 healthy controls performed a passive avoidance task with a reversal phase under three motivational conditions, using naturalistic rewards. The subjective values of the rewards were assessed a priori for each individual participant using a visual analogue scale. The correspondence of these values to their internal representation was confirmed by analyses of brain potentials. Analyses using both signal detection theory and classical approaches indicated that psychopathic offenders performed worse compared to the other groups during passive avoidance learning. However, using the signal detection approach, we found this deficiency to be present only when a hypothetical reward was used (‘neutral reward’ condition), whereas psychopathic offenders performed similar to the other groups when naturalistic rewards could be obtained (‘low reward’ and ‘high reward’ conditions). Furthermore, traditional analyses suggested that psychopathic offenders had more hits than the other groups during reversal learning, but the signal detection approach indicated that no effects of group or condition were present. Analysis of win-stay and lose-shift behaviour showed that psychopathic offenders were less likely to stay with a rewarded response during passive avoidance learning in the neutral reward condition. In addition, regardless of experimental phase or condition, psychopathic offenders were less likely to stop responding to a particular stimulus after receiving negative feedback. Although the approaches employed did not lead to unequivocal results, our findings suggest that psychopathic offenders do have the ability to adapt their behaviour to environmental contingencies when positive reinforcers with sufficiently high subjective values are used.

Is Psychopathy a Mental Disorder or an Adaptation? Evidence From a Meta-Analysis of the Association Between Psychopathy and Handedness.

Psychopathy has historically been conceptualized as a mental disorder, but there is growing evidence that it may instead be an alternative, adaptive life history strategy designed by natural selection. Although the etiology of mental disorders is not fully understood, one likely contributor is perturbations affecting neurodevelopment. Nonright-handedness is a sign of such perturbations, and therefore can be used to test these competing models. If psychopathy is a mental disorder, psychopaths should show elevated rates of nonright-handedness. However, an adaptive strategy perspective expects psychopaths to be neurologically healthy and therefore predicts typical rates of nonright-handedness. We meta-analyzed 16 studies that investigated the association between psychopathy and handedness in various populations. There was no difference in the rates of nonright-handedness between community participants high and low in psychopathy. Furthermore, there was no difference between psychopathic and nonpsychopathic offenders in rates of nonright-handedness, though there was a tendency for offenders scoring higher on the Interpersonal/Affective dimension of psychopathy to have lower rates of nonright-handedness, and for offenders scoring higher on the Behavioral dimension of psychopathy to have higher rates of nonright-handedness. Lastly, there was no difference in rates of nonright-handedness between psychopathic and nonpsychopathic mental health patients. Thus, our results fail to support the mental disorder model and partly support the adaptive strategy model. We discuss limitations of the meta-analysis and implications for theories of the origins of psychopathy.

Salivary cortisol patterns in psychopathic and non-psychopathic offenders

Previous research has described diverse biological correlates of the psychopathic personality. Efforts to understand the underpinnings of low fear responses in psychopathic individuals have drawn attention to the possible role of abnormalities in hypothalamic-pituitary-adrenal (HPA) axis function, but studies to date have been largely limited to youth or to adult community samples. The current study therefore examined morning basal cortisol levels and responses to a psychosocial stress task in a forensic clinical sample of psychopathic offenders (n = 14), non-psychopathic offenders (n = 22), and non-offender controls (n = 14). Morning cortisol levels were similar in all three groups. Throughout the stress task, psychopathic offenders showed significantly lower cortisol than controls; non-psychopathic offenders showed a similar but non-significant trend towards lower cortisol. The three groups did not differ, however, in cortisol response slopes. Implications of these findings are discussed in the framework of current theories about biological mechanisms underlying psychopathic personality.

Female Psychopathy and Aggression: A Study with Incarcerated Women and Rorschach Aggression Scores

ABSTRACT Psychopathy is an essential construct in forensic mental health. While male psychopathy and aggression has been thoroughly studied, less is known about this relationship with female psychopathy. In this article, the relationship between female psychopathy (Psychopathy Checklist-Revised [PCL-R] total, factor, and facet scores) and the Rorschach Aggression indices (Aggressive Movement [AG], Aggressive Content [AgC], Aggressive Past [AgPast], Aggressive Potential [AgPot], Sadomasochistic Aggression [SM]) were examined. Rorschach Aggression indices between female psychopathic (PCL-R total score ≥ 30; N = 84) and non-psychopathic female offenders (PCL-R total score ≤ 24; N = 39) were also compared. PCL-R total score was significantly correlated (p <.05) with AgC, AgPast, AgPot, and SM and there were also significant correlations between the Aggression scores and PCL-R Factor/facet scores. The female psychopaths produced more AgC, AgPast, and AgPot responses than the non-psychopathic females. Rorschach aggression indices supported theory and suggested that the violence in psychopathic women stems from their identification with aggression and pervasive feelings of entitlement. Psychopathic women evidenced higher levels of these variables than the non-psychopathic offenders. The results add to the link between aggression and psychopathy as well as a better understanding of aggression in female offenders.

A Motivational Framework for Psychopathy: Toward a Reconceptualization of the Disorder

Abstract. The link between psychopathy and violence has been well documented. Estimates suggest psychopathic offenders are responsible for as much as 40% of violence-related crime, and that they show rates of violent recidivism up to five times higher than non-psychopathic offenders. Existing theories of the disorder argue that this violence stems from a core insensitivity to emotional/aversive information, or from a core inability to optimally allocate processing resources in complex environments. However, some newer findings have been difficult for existing theories to assimilate; moreover, successful treatment programs based off current conceptualizations have been slow to develop. With this in mind, the current paper proposes a new motivational framework for psychopathy, within which the disorder is conceptualized as stemming from more strategic, motivated processes. The paper begins by reviewing traditional theories of psychopathy and highlighting their explanatory strengths and limitations. The proposed motivational framework is then outlined, and a supportive rationale for the framework provided. Next, the paper undertakes a selective review of some of the most empirically supported features of the disorder, to highlight how these features may be productively reformulated within a motivational framework. Finally, the paper suggests several methods through which an empirical evaluation of the proposed ideas may be undertaken, and explores potential implications of a motivational framework for next-generation rehabilitation and treatment opportunities.

Impaired attention toward the eyes in psychopathic offenders: Evidence from an eye tracking study

Attention orienting to socially salient cues, such as the eyes of interaction partners, is assumed to be crucial for the development of intact social cognition. Dysfunctions in such basic processes that guide the perception of social cues have been suggested to play a role in the development of psychopathy. The present study investigated gaze patterns in two groups of incarcerated psychopathic and non-psychopathic offenders. While recording their eye movements, participants were asked to categorize either gender (task 1) or emotional expression (task 2) of facial images. Psychopaths exhibited significantly reduced attention orienting toward the eyes, as indicated by absolute dwell time as well as frequency of the initial fixation on the eye region. This pattern was evident across all emotional expressions and independent of the task. The present results suggest a pervasive impairment to attention orienting toward the eyes in psychopaths compared to non-psychopathic offenders. This impairment appears to affect not only general attention but also early attention shifts. Thus, our findings provide evidence that these dysfunctions might particularly contribute to the development of psychopathy instead of antisocial behavior per se. Future studies should further examine the origin, emergence, and consequences of these impairments in order to develop targeted interventions.

Psychopathy and its relation to personality psychopathology in a South African female forensic context

There is a paucity of research about personality pathology among female offenders. This study aims to address this gap in the forensic psychology empirical base by examining the relationship between female psychopathy, as measured by the Psychopathy Checklist–Revised, and personality disorders, as measured by the Millon Clinical Multiaxial Inventory-III in a South African forensic context. Participants included 108 purposively sampled female offenders incarcerated in South Africa. The Kruskal–Wallis H test and Mann–Whitney U test revealed a number of significant differences in levels of personality pathology between groups. Importantly, the results support international findings that significantly higher rates of Cluster B personality pathology are found among psychopathic offenders compared to non-psychopathic offenders.

Implicit vs. explicit dimensions of guilt and dominance in criminal psychopathy

The current study investigated the relationship between psychopathy and two concepts that hold a central position in conceptualizations of this disorder, being guilt and dominance. Both constructs were measured using explicit measures (i.e., self-report), as well as indirect assessment (i.e., the Single Category Implicit Association Test; Sc-IAT). Our sample consisted of 43 psychopathic offenders, 42 nonpsychopathic offenders, and 26 nonoffender controls. Although no overall group differences emerged, the lifestyle/antisocial traits of psychopathy (Factor 2) predicted reduced self-reported guilt on a dimensional level. As hypothesized, such a relationship was absent for the interpersonal/affective dimension of psychopathy (Factor 1). Psychopathy was unrelated to implicit self-guilt associations. Regarding dominance, psychopathy was not significantly associated with indirectly or explicitly assessed dominance. These findings are interpreted in the light of empirical knowledge on moral emotions, insight and response distortion in highly antisocial offenders.

Investigating Characteristics of the Nonrecidivating Psychopathic Offender

Psychopathic offenders are at higher risk to violently reoffend than nonpsychopathic offenders; however, about one in four psychopathic offenders are not reconvicted for a violent offense even over extended follow-ups. The characteristics of nonrecidivating psychopathic offenders (NRPs) remain underexamined. In a sample of 123 offenders with a minimum Hare Psychopathy Checklist–Revised (PCL-R) score of 25, community follow-up of 5 years, and 4 months in a violence reduction program, 65 men receiving a violent conviction within 5 years (recidivating psychopathic offenders [RPs]) were compared with 58 who had not (NRPs). Comparatively, NRPs were older at release, had better community support, and were rated lower violence risk. NRPs also had significantly lower PCL-R Factor 2 scores, but higher Factor 1 scores. Post hoc analyses revealed prominent NRP characteristics included exploitative personality traits and a predilection for instrumentally violent crimes. Findings are discussed in terms of their implications for the risk assessment and treatment of psychopathic offenders.

The Mask of Sanity: Facial Expressive, Self-Reported, and Physiological Consequences of Emotion Regulation in Psychopathic Offenders.

This study investigated the physiological, self-reported, and facial correlates of emotion regulation in psychopathy. Specifically, we compared psychopathic offenders (n = 42), nonpsychopathic offenders (n = 42), and nonoffender controls (n = 26) in their ability to inhibit and express emotion while watching affective films (fear, happy, and sad). Results showed that all participants were capable of drastically diminishing facial emotions under inhibition instructions. Contrary to expectation, psychopaths were not superior in adopting such a "poker face." Further, the inhibition of emotion was associated with cardiovascular changes, an effect that was also not dependent on psychopathy (or its factors), suggesting emotion inhibition to be an effortful process in psychopaths as well. Interestingly, psychopathic offenders did not differ from nonpsychopaths in the capacity to show content-appropriate facial emotions during the expression condition. Taken together, these data challenge the view that psychopathy is associated with either superior emotional inhibitory capacities or a generalized impairment in showing facial affect.

Denial of risk: The effects of positive impression management on risk assessments for psychopathic and nonpsychopathic offenders

Risk assessments for offenders often combine past records with current clinical findings from observations, interviews, and test data. Conclusions based on these risk assessments are highly consequential, sometimes resulting in increased criminal sentences or prolonged hospitalization. Therefore, many offenders are motivated to intentionally minimize risk factors and their negative consequences. Positive impression management (PIM) is especially likely to occur in offenders with high psychopathic traits because goal-directed deception is reflected in several of psychopathy's core traits of the disorder, such as manipulativeness, glibness, and superficial charm. However, this connection appears to be based on the conceptual understanding of psychopathy, and has rarely been examined empirically for either frequency of or success at deception. The current study examined the ability of a jail sample to intentionally minimize risk factors and related criminal attributes using a repeated measures, simulation design. In general, offenders were able to effectively use PIM to lower scores on the HCR-20 and the Self-Appraisal Questionnaire (SAQ), while the Psychological Inventory of Criminal Thinking Styles (PICTS), as a measure of cognitive styles, was more resistant to such minimization. Psychopathic traits, especially high Factor 1 scores (i.e., affective/interpersonal), were associated with greater PIM. Important differences in the willingness and ability to use deception were found based on the (a) mode of administration (i.e., interview vs. self-report) and (b) level of psychopathy as measured by the Psychopathy Checklist — Revised (PCL-R). The important implications of this research are discussed for risk assessment procedures regarding likely areas of deception and its detection. The current research also informs the growing literature on the connection between psychopathic traits and deception.

Examining the influence of psychopathy, hostility biases, and automatic processing on criminal offenders' Theory of Mind

Theory of Mind (ToM) is a social perceptual skill that refers to the ability to take someone else's perspective and infer what others think. The current study examined the effect of potential hostility biases, as well as controlled (slow) versus automatic (fast) processing on ToM performance in psychopathy. ToM abilities (as assessed with the Reading the Mind in the Eyes Test; RMET; Baron-Cohen, Wheelwright, Hill, Raste, & Plumb, 2001), was compared between 39 PCL-R diagnosed psychopathic offenders, 37 non-psychopathic offenders, and 26 nonoffender controls. Contrary to our hypothesis, psychopathic individuals presented with intact overall RMET performance when restrictions were imposed on how long task stimuli could be processed. In addition, psychopaths did not over-ascribe hostility to task stimuli (i.e., lack of hostility bias). However, there was a significant three-way interaction between hostility, processing speed, and psychopathy: when there was no time limit on stimulus presentation, psychopathic offenders made fewer errors in identifying more hostile eye stimuli compared to nonoffender controls, who seemed to be less accurate in detecting hostility. Psychopaths' more realistic appraisal of others' malevolent mental states is discussed in the light of theories that stress its potential adaptive function.

Verbal Functions in Psychopathy.

The aim of this study was to compare the verbal functions and language skills of male psychopathic individuals (in prison and outside) with non-psychopaths. The purpose was therefore to analyze phonological processing, reading and writing skills, the meaning of words and images, and the understanding of sentences. Ninety individuals with an average age of 38.19 (SD = 7.67) voluntarily participated in this study. The data were collected in different settings: prisons, a private charitable organization, and private clinics and health centers. All participants completed the Psychopathy Checklist Revised and the Psycholinguistic Assessment of Language Processing in Aphasia, to assess psychopathy traits and language skills, respectively. Participants were allocated into four different groups: incarcerated psychopathic offenders (n = 13), non-incarcerated psychopathic non-offenders living in the community (n = 13), incarcerated non-psychopathic offenders (n = 25), and non-psychopathic non-offenders living in the community (n = 39). The results showed that the verbal functions and language skills between psychopaths and non-psychopaths are very similar, showing a common profile. The data presented indicate the need for more specific work opportunities for both groups within the correctional setting, with the use of appropriate language and individualized programs as necessary.

Reduced susceptibility to the attentional blink in psychopathic offenders: implications for the attention bottleneck hypothesis.

Newman and Baskin-Sommers (in press) have proposed that psychopathy reflects an attention bottleneck that interferes with processing contextual information, including the timely processing of affective and inhibitory cues that initiate self-regulation. Despite a wealth of evidence that attention moderates the affective, inhibitory, and self-regulation deficits of psychopathic offenders, to date there is little or no evidence that psychopathic offenders perform abnormally on a canonical measure of selective attention. In this study, we address this gap in the literature and clarify the attention-related abnormality in psychopathy. We administered the attentional blink (AB) task to 37 male prisoners assessed with Hare's (2003) Psychopathy Checklist-Revised. In the AB paradigm, participants identify targets in a rapid serial visual presentation. Distracters' temporal proximity to the first target elicits a conflict between attending to the target and attending to the distracters. Greater conflict results in a larger AB (i.e., reduced accuracy for the second target). As predicted, psychopathic offenders displayed a significantly smaller AB (i.e., better accuracy throughout the blink interval) than nonpsychopathic offenders. Consistent with the attentional bottleneck hypothesis, psychopathic participants were less susceptible to distracter effects following presentation of an initial target. The results clarify the nature of the attention bottleneck in psychopathy, the circumstances in which it enhances versus interferes with performance, and its implications for more ecologically valid conditions involving the sequential presentation of goal-relevant and goal-incongruent information.

Change during forensic treatment in psychopathic versus nonpsychopathic offenders

Psychopathy in forensic psychiatric patients and other criminal offenders is associated with higher criminal recidivism rates. Moreover, many forensic mental health professionals believe that psychopaths are not amenable to treatment. The present study examines whether patients with psychopathy demonstrate change during forensic psychiatric treatment. Seventy-four personality disordered offenders who had been convicted for serious violence were rated on the the Hare Psychopathy Checklist-Revised and assessed repeatedly on risk-related behaviors during 20-months of inpatient forensic treatment. Group- and individual-level analyses showed no significant differences between psychopathic and non-psychopathic patients on adaptive social behavior, communication skills, insight, attribution of responsibility, and self-regulation strategies. However, a subgroup of psychopaths (22%) deteriorated during treatment with regard to physical aggression, whereas none of the non-psychopathic patients did (p < 0.01). Our findings demonstrate that, contrary to clinical lore, treatment does not make a majority of psychopaths worse, but there are significant differences between psychopaths and non-psychopaths in treatment responsiveness.

Psychopathy and verbal indicators of deception in offenders

Although psychopathic offenders frequently lie and manipulate others, it is unclear what strategies they use and whether there are differences between psychopathic and non-psychopathic offenders. The present study examined the association between psychopathy and verbal indicators of deception in a sample of 45 adult male offenders. Verbal indicators of deception were assessed using Statement Validity Assessment (SVA). Psychopathic offenders provided more appropriate detail and spontaneous corrections when lying. In addition, interpersonal symptoms of psychopathy were associated with the perceived credibility of lies. Although offering limited support for SVA in a forensic context, the findings suggest that it may be necessary to attend to unique indicators of deception in psychopathic offenders.

Stroop tasks associated with differential activation of anterior cingulate do not differentiate psychopathic and non-psychopathic offenders

Attentional models of psychopathy hold that psychopathic individuals fail to process information that conflicts with goal-directed behavior. However, they display normal interference on color-word Stroop tasks. To determine whether psychopathic individuals’ attention deficits are specific to conditions associated with the anterior cingulate (ACC) conflict monitoring system, we administered a Stroop task with a mostly-congruent condition associated with ACC activation, and a mostly-incongruent condition that is not, to 128 criminal offenders assessed for psychopathy using Hare’s (2003) PCL-R. Despite replicating previous condition effects associated with differential ACC activation (Carter et al., 2000), psychopathic offenders and controls performed very similarly in both conditions. Results do not support an association between ACC-related deficits in conflict monitoring and the attention deficits of psychopathic offenders.

Forming, switching, and maintaining mental sets among psychopathic offenders during verbal and nonverbal tasks: Another look at the left-hemisphere activation hypothesis

Three hypotheses for cognitive deficits among psychopaths were tested: executive dysfunction, left hemisphere activation, and an interaction between the two. Twenty-one psychopathic and 23 nonpsychopathic criminal offenders identified with the Hare Psychopathy Checklist-Revised participated in verbal and visual-spatial tasks during which the level of executive processing demands was manipulated. Consistent with prior research, psychopathic offenders made more errors than controls, but only during the verbal task and only on trials with high executive demand. Within those trials, most errors occurred when set-maintenance demands were the highest. No response latency differences between groups were found.
