Psychopathic traits from the perspective of self and informant reports: Is there evidence for a lack of insight?

It has been suggested that psychopathic individuals are incapable of providing valid reports on their own personality functioning because they are either unwilling (i.e., pathologically lie) or unable (i.e. lack insight) to do so. Despite the long-standing nature of this suggestion, almost no empirical research exists on this topic. In the current study, the authors examined the issue of psychopathy and insight by testing self and informant convergence and mean level differences across 3 indices of psychopathy in a community sample (N = 64). Self- and informant-report psychopathy scores were also examined in relation to self and informant reports on traits from the Five-Factor Model (FFM). Convergence was strong across the 3 psychopathy indices and their respective factors (i.e., median r = .64), and there was only modest evidence that individuals rated themselves as less psychopathic than did informants. In addition, the same FFM domains—low Agreeableness and Conscientiousness—characterized individuals with psychopathic traits regardless of reporter. Psychopathic individuals appear capable of reporting accurately on psychopathic traits when there are no direct consequences to accurate reporting (i.e., sentencing). It may be that the lack of concern for the consequences of these traits has been mistaken for a lack of insight into them. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Statistical analysis of dyadic social behavior.

Describes a method for determining the effects of sex (or any other dichotomous characteristic) from the individual correlated behavioral responses observed in dyadic interactional situations. In the illustration used, the dyads are of 3 types: girl–girl, girl–boy, and boy–boy. Main effects of sex of S and of sex of partner and interaction effects are estimated and tested, using a generalization of the matched-pair t-test approach. Intragroup correlations between paired responses are examined separately. Alternative procedures of analysis are discussed and compared. The present method is extended to interacting groups larger than dyads when the S characteristic remains dichotomous (e.g., boys and girls in groups of 3, 4, etc). In these cases there are 3 intragroup correlations of interest for responses within the same interacting groups: boys vs boys, boys vs girls, and girls vs girls.

Disentangling the Underlying Dimensions of Psychopathy and Conduct Problems in Childhood: A Community Study.

The psychometric and predictive validity of callous-unemotional (CU) traits as an early precursor of conduct disorder and antisocial behavior were assessed. A community sample of children (4-9 years of age) were tested 12 months apart with the Antisocial Process Screening Device (APSD; P. J. Frick & R. D. Hare, 2002), a measure of early signs of psychopathy in children. Factor analysis supported the structure of the APSD. Given controversy surrounding construct overlap between psychopathy and conduct problems, a factor analysis was conducted on pooled items from the Strengths and Difficulties Questionnaire and APSD. A 5-factor solution resulted: antisocial, hyperactivity, CU traits, anxiety, and peer problems. CU traits added small but significant improvements in the 12-month prediction of antisocial behavior for boys and older girls, after controlling for Time 1 measures. These results indicate that although the dimensions of the APSD overlap with dimensions of the disruptive behavior disorders, CU traits have unique predictive validity in childhood.

Gender differences in temperament: A meta-analysis.

The authors used meta-analytical techniques to estimate the magnitude of gender differences in mean level and variability of 35 dimensions and 3 factors of temperament in children ages 3 months to 13 years. Effortful control showed a large difference favoring girls and the dimensions within that factor (e.g., inhibitory control: d = -.41, perceptual sensitivity: d = -0.38) showed moderate gender differences favoring girls, consistent with boys' greater incidence of externalizing disorders. Surgency showed a difference favoring boys, as did some of the dimensions within that factor (e.g., activity: d = 0.33, high-intensity pleasure: d = 0.30), consistent with boys' greater involvement in active rough-and-tumble play. Negative affectivity showed negligible gender differences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Same-gender and cross-gender peer acceptance and peer rejection and their relation to bullying and helping among preadolescents: Comparing predictions from gender-homophily and goal-framing approaches.

The relation between bullying and helping and same-gender and cross-gender peer acceptance and peer rejection was examined in a sample of preadolescents aged 11 and 12 years (N=1,065). The authors tested predictions from a gender-homophily approach vs. predictions from a goal-framing approach in which acceptance and rejection are seen as being generated by approach and avoidance goals, respectively. For preadolescents, both approaches predicted a central role for gender, but the gender-homophily approach predicted symmetrical effects for acceptance and rejection, whereas the goal-framing approach predicted strong asymmetries. The data supported the goal-framing approach. The most important findings were that for preadolescents, acceptance is much more frequent and much more gendered than rejection; the absolute impact of helping on acceptance is much larger than that of bullying (and vice versa for rejection); for acceptance, there is a prototypicality effect (i.e., boys accept bullying girls better than nonbullying girls, and girls accept helping boys better than nonhelping boys); and for acceptance, there is a cross-gender ignorance effect (i.e., boys ignore helping in girls, and girls ignore bullying in boys).

Psychopathic personality traits associated with abnormal selective attention and impaired cognitive control.

The current study investigated how mechanisms of attention that have been well-characterized in the cognitive psychology literature (Lavie, Hirst, De Fockert, & Viding, 2004; Maylor & Lavie, 1998) may be differentially associated with psychopathic traits in nonincarcerated men. Previous research on cognition and psychopathy indicated that primary psychopathic traits were associated with overfocused attention and/or reduced processing of information peripheral to the focus of attention. Conversely, deficits in executive functioning, such as working memory and cognitive control, were implicated in secondary psychopathic traits. Results revealed a significant relationship between traits typically associated with primary psychopathy (e.g., low anxiety, social dominance, fearlessness, callousness) and reduced processing of task-irrelevant distractors, suggesting diminished basic attentional capacity among individuals high on these traits. In contrast, some characteristics linked to secondary psychopathy (e.g., social alienation, cynicism) showed a positive relationship with impaired working memory functioning, indicative of deficits in cognitive control, whereas other traits (i.e., self-centeredness, antagonism) did not. These results suggest that psychopathic traits are differentially related to selective impairments in attentional functioning, which may help explain the observed heterogeneity in psychopathic manifestations.

Reduced Electrodermal Activity in Psychopathy-Prone Adolescents.

This study tests the hypothesis that psychopathy-prone adolescents show reduced anticipatory skin conductance responding. Electrodermal activity was recorded while participants anticipated and responded to a 105dB signaled or unsignaled white-noise burst. Using an extreme groups design, the authors used Child Psychopathy Scale (D. R. Lynam, 1997) scores from a community sample of 335 male adolescents (age 16) to form control (n=65) and psychopathy-prone (n=65) groups. Significantly more psychopathy-prone participants were nonresponders in the signaled anticipatory (p=.014), signaled responsivity (p=.037), and unsignaled responsivity (p=.003) conditions compared with controls. Anticipatory hyporesponsivity of psychopathy-prone adolescents similar to the electrodermal hyporesponsivity found in psychopathic adults suggests that this autonomic impairment is present by adolescence and may predispose individuals to adult psychopathy.

Maturation of personality in adolescence.

The present research assesses adolescent personality maturation by examining 3 measures of change and stability (i.e., mean-level change, rank-order stability, and profile similarity) of Big Five personality traits, employing data from a 5-annual-wave study with overlapping early to middle (n = 923) and middle to late (n = 390) adolescent cohorts. Results indicated that mean levels of Agreeableness and Emotional Stability increased during adolescence. There was mixed evidence for increases in Extraversion and Openness. Additionally, rank-order stability and profile similarity of adolescent personality traits clearly increased from early to late adolescence. For all change facets, the authors found evidence for gender differences in the timing of adolescent personality maturation, as girls were found to mature earlier than boys.

Psychopathy and suicide: A multisample investigation.

Evidence suggests that behavioral aspects of psychopathy are associated with suicidal behavior, whereas the affective and interpersonal aspects are not. The authors tested the robustness of this bifurcated association across 1,711 persons and 12 samples of adult and juvenile criminal offenders, forensic psychiatric patients, and civil psychiatric patients. The authors observed a small but significant partial correlation (.13) between the behavioral/impulsive lifestyle features of psychopathy and suicidality, but no effect for affective/interpersonal features. Several method and sample features (mental disorder; psychopathy and suicidality measurement format) significantly strengthened or weakened this association. The authors conclude that it is not possible to speak of "the" association between psychopathy and suicide, but that this relationship appears to be partially dependent on methodological (i.e., self-report vs. clinician-administered psychopathy measures) and sample composition (i.e., age; mental illness) factors. Recommendations for practice are provided, including that clinicians should not consider psychopathy a buffer against suicidal behavior.

Gender, ethnic, and body type biases: The generality of prejudice in childhood.

From a very young age, children show signs of prejudice. However, it is not clear whether those who are the most biased in one domain (e.g., gender) are also the most biased in other domains (e.g., ethnicity). This study addressed the issue using multiple measures of prejudice (negative bias) in 3 domains: gender (male, female), ethnicity-language (French Canadian, English Canadian), and body type (overweight, normal weight). The flexibility of attitudes (i.e., the belief that people from different categories can possess similar traits) was also assessed. A total of 254 children (127 boys, 127 girls) in kindergarten to Grade 6 participated. Children demonstrated clear biases against groups to which they did not belong, although attitudes became more flexible and prejudice declined somewhat with age. There was little predictive power across domains; that is, there was no evidence that prejudice represents a general characteristic that differentiates children.

Personality trait development from age 12 to age 18: Longitudinal, cross-sectional and cross-cultural analyses.

Three studies were conducted to assess mean level changes in personality traits during adolescence. Versions of the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992a) were used to assess the 5 major personality factors. A 4-year longitudinal study of intellectually gifted students (N = 230) was supplemented by cross-sectional studies of nonselected American (N = 1,959) and Flemish (N = 789) adolescents. Personality factors were reasonably invariant across ages, although rank-order stability of individual differences was low. Neuroticism appeared to increase in girls, and Openness to Experience increased in both boys and girls; mean levels of Extraversion, Agreeableness, and Conscientiousness were stable. Results extend knowledge of the developmental curve of penalty traits backward from adulthood and help bridge the gap with child temperament studies.

An examination of the structure of self-report psychopathy measures and their relations with general traits and externalizing behaviors.

Self-report assessment of psychopathy is plagued by inconsistencies among the relations of the various psychopathy factors. We examined the factor structure of 3 prominent self-report measures of psychopathy—the Self-Report Psychopathy Scale–III (SRP–III; Williams, Paulhus, & Hare, 2007), the Levenson Self-Report Psychopathy Scale (LSRP; Levenson, Kiehl, & Fitzpatrick, 1995), and the Psychopathic Personality Inventory–R (PPI–R; Lilienfeld & Widows, 2005). A coherent 4-factor structure resulted from conducting an exploratory factor analysis (EFA) of the psychopathy subscales along with the domains from the five-factor model. Two of these factors were consistent with traditional conceptualizations of a 2-factor structure of psychopathy (i.e., Factor 1, which loaded negatively with Agreeableness; Factor 2, which loaded negatively with Conscientiousness), while 2 additional factors emerged, 1 of which emphasized low Neuroticism and 1 of which emphasized traits related to novelty/reward-seeking and dominance-related personality traits (high Extraversion). We also investigated the relations of these factors with a variety of externalizing behaviors (EB). The psychopathy scales indicative of interpersonal antagonism (i.e., Factor 1) were most consistently and strongly related to EB. Our findings are discussed in terms of the importance of a trait-based perspective in the assessment of psychopathy. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Developmental sex differences in global-local perceptual bias.

Previous developmental studies have indicated that boys tend to perform better than girls on tasks associated with the right hemisphere (e.g., spatial tasks), whereas girls perform better on tasks associated with the left hemisphere (e.g., verbal tasks). Extending this body of literature to what is known about hemispheric specialization of visuospatial processing, we predicted that boys would be more global than girls in their perception of visual hierarchical stimuli. Forty girls and 39 boys between the ages of 4 and 12 years were administered a perceptual judgment task previously used by Kimchi and Palmer (see record 1983-02534-001). Boys were significantly more global in their perceptual judgments than girls at all ages. Younger children of both sexes were less global than older children. Results were consistent with developmental models that suggest an early left-hemisphere advantage for girls and a right-hemisphere advantage for boys.

Behavioral and Physiological Measures in the Detection of Concealed Information.

The authors examined the incremental validity of the reaction time (RT) measure beyond that of skin conductance response (SCR) in the detection of concealed information. Participants performed a Stroop-like task in which they named the color of critical and neutral words. Results show that the SCR highly differentiated between the relevant and neutral words. However, the RT demonstrated a significant differentiation only when the critical words denoted personally significant items (e.g., one's own name) and not when they denoted crime-relevant items related to a simulated crime. In both cases, combining the 2 measures yielded no advantage over the use of SCR alone. Thus, although behavioral measures may differentiate between relevant and neutral information in some cases, their practical use is questionable.

Is the hypnotized subject lying?

Do the verbal reports of deeply hypnotized Ss truthfully reflect their subjective experiences of hypnotic suggestions? Exp 1 established that the electrodermal skin conductance response (SCR) provides an effective method for detecting deception in the laboratory equally well in hypnotized and nonhypnotized Ss. In Exp 2, deeply hypnotized and simulating Ss were administered a number of hypnotic suggestions in a typical hypnotic session, without mention of deception, and were questioned about their experiences while SCR measures were recorded concurrently. Results indicate that 89% of the hypnotized Ss' reports met the criterion for truthfulness, whereas only 35% of the simulators' reports met this criterion. Implications for the theory of hypnosis are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assessing the forms and functions of aggression using self-report: Factor structure and invariance of the Peer Conflict Scale in youths.

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed.

Using a Five-Factor Lens to Explore the Relation Between Personality Traits and Violence in Psychiatric Patients.

Recent work suggests that predictors of violence are similar for individuals with and without mental illness. Although psychopathy is among the most potent of such predictors, the nature of its relation to violence is unclear. On the basis of a sample of 769 civil psychiatric patients, the authors explore the possibility that measures of psychopathy provide a glimpse of higher order personality traits that predispose individuals toward violence. Results indicate that general traits captured by a measure of the 5-factor model, particularly antagonism, were relatively strongly associated with violence and shared most of their violence-relevant variance with a leading measure of psychopathy. Because interpersonal and affective features of psychopathy are less important than basic traits of antagonism in postdicting violence, it may be appropriate to broaden focus in risk assessment to patients' basic personality traits.

Links Between Sex-Typed Time Use in Middle Childhood and Gender Development in Early Adolescence.

The authors studied sex-typing in the kinds (e.g., sports, handicrafts) and social contexts (same- vs. other-sex companions) of children's free time activities, and the links between sex-typed activities and gender development over 2 years. Participants were 200 White, working- and middle-class children (103 girls, 97 boys; mean age = 10.86 years). In annual home interviews, children rated their self-esteem, gender role attitudes and sex-typed personality qualities, academic interests, and school grades. During 7 nightly phone interviews each year, children reported on their activities. Boys were more sex-typed than girls in their peer activities, and children were least sex-typed in their activities with siblings. Sex-typed activities in middle childhood predicted individual differences in gender development in early adolescence (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychopathy in a noninstitutional sample: Differences in primary and secondary subtypes.

Early theoretical conceptualizations suggest psychopathy is a heterogeneous construct whereby psychopathic individuals are found in diverse populations. The current study examined male and female psychopathy subtypes in a large sample of undergraduate students (n = 1229). Model-based cluster analysis of the Psychopathic Personality Inventory-Short Form (PPI-SF) revealed two clusters in both male and female students. In males, the primary subtype evidenced greater psychopathic personality traits (i.e., Social Potency, Fearlessness, and Impulsive Nonconformity) and lower anxiety (i.e., higher Stress Immunity), whereas the secondary subtype displayed fewer psychopathic personality traits (i.e., Machiavellian Egocentricity and Blame Externalization) and higher anxiety (i.e., lower Stress Immunity). In females, the primary subtype exhibited higher scores across all PPI-SF subscales and lower anxiety whereas the secondary subtype reported lower PPI-SF subscale scores and higher anxiety. Across a diverse array of personality, affective, and behavioral external correlates, differences between the subtypes and with nonpsychopaths emerged. Implications for psychopathy in noninstitutional populations with respect to theory, research, and gender are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of visual alcohol cues on alcoholics' autonomic arousal.

Determined whether visual alcohol cues alone (slides showing drinking environments and alcohol beverage bottles) were sufficient to elicit autonomic arousal. 82 male alcoholics (aged 25–64 yrs) were shown alcohol-related or control slides while electrodermal responses were being recorded. Each slide was presented for 4 sec and interstimulus intervals varied between 20 and 30 sec. The frequency of skin conductance responses (SCRs) and the amplitude of the first SCR to each picture presentation were greater to alcohol slides than to control slides. The Ss showed slower habituation to alcohol-related slides as compared with control slides. Pictures of hard liquor yielded higher SCR amplitudes than did pictures of beer.
