How are psychopathic traits and sadism related to executive functioning in a general population sample? Sadism related to enhanced functions, but Erratic Lifestyle, Callous Affect and Antisocial Behavior each related to reduced functional impairment: tinyurl.com/3k46aze6

Persistence of psychopathic traits and related offending in young people, turning points have little impact: tinyurl.com/4emmb23s

Young people with callous-unemotional traits who are easily cognitively overloaded show less prosocial behavior, but those not affected by cognitive demands don't show such reduction: tinyurl.com/ycyac5en

Great discussion by Eva Kimonis and colleague of a paper discussing reflections of health carers about "difficult-to-treat" veteran clients, touching on psychopathy and callous-unemotional traits - a call to work on this: tinyurl.run/aZU1pe @ssspsychopathy.bsky.social

New meta analysis shows that (mainly secondary) psychopathy is related to lower task performance, worse organizational citizenship behavior and more counterproductive work behavior: tinyurl.run/xGe8ow

Not peer victimization but harsh parenting found to be related to higher CU traits, especially in those highly irritable, and lower cortisol related to higher CU traits: tinyurl.com/4y49dkt6

Less warm parenting due to more parental stress seems to be aggravated by callous-unemotional traits in young people with conduct problems - very relevant and needs replication in a larger sample: tinyurl.com/mws4bx7r

Higher callous-unemotional traits in young people with conduct problems are related to more gun violence, which is mediated by maternal hostility (but not by parenting practices nor maternal warmth): tinyurl.com/4yv3aw92

Great review on the role of molecules for callous-unemotional traits: tinyurl.com/53nkmeu7

Network analysis for the PCL-R: finding both, a one factor and a four-factor-structure; Lack of Empathy showed strongest connection to all four factors: tinyurl.com/5fmcx87j

Structural connectome-based analysis of young adults showed positive associations with social-affective, language and reward processing regions, and negative associations with attention modulation regions - BUT only based on the short dark triad measure! tinyurl.com/2due9wnb

Women with lethal violent convictions and severe mental disorder shown to have lower PCL-R total and interpersonal facet scores, and higher arousal and planning related to their offense: tinyurl.com/mwxffbzz

To be expected coming at some point: a suggestion for an algorithm deriving "psychopathy" from 68 pieces of information (parental, interpersonal, personality, psychological, socio-demographic, prison behavior) - 87% accuracy in matching PCL-R levels: tinyurl.com/mr334bp2

Maternal parenting stress and paternal helplessness found to be related to higher child callous-unemotional traits (controlling for conduct problems): tinyurl.com/58wzy5hp

New study by colleagues from our department shows how voters varying in authoritarianism vary in how much psychopathic traits they assigned to candidates for presidency: ejop.psychopen.eu/index.php/ej...

Poster: Exploring the relationship between conduct problems, callous-unemotional traits, and executive function in middle childhood Friday, May 2, 2025 4:40 PM Poster Number: 161

The SSSP Early Career Event (online) is just one week away and a program packed with new research on psychopathy and callous-unemotional traits is waiting for you: check out the details and register to attend here: psychopathysociety.org/page/ECE2025

Fun question for all my SSSP Psychopathy researchers. Do you watch shows/movies about psychopaths? (You, Adolescents, etc) @ssspsychopathy.bsky.social

Academia isn’t perfect, but it offers a rare space to pursue knowledge for its own sake. If research were fully privatized, only profit-driven questions would get asked. Yet many of the most transformative discoveries began as curiosity-driven inquiries whose value wasn’t clear for years.

Please share!

Happy to report this work was accepted for publication in the Journal of Affective Disorders and can be found here: doi.org/10.1016/j.ja...

Are callous-unemotional (CU) traits purely affective, or do they also involve cognitive processes? A recent RCT finds CU traits uniquely linked to cognitive-affective interaction difficulties that also associated with antisocial behavior. doi.org/10.31234/osf...

Very excited that our meta-analysis is now published: no matter if psychopathic personality is self-reported or interview-/record-based rated, there seem no consistent effects on emotional reactivity: tinyurl.com/bdd5ebbd - great collaboration with colleagues from @ssspsychopathy.bsky.social

Submissions for the SSSP Early Career Event, our virtual biannual conference for students and early-career professionals held May 7-9, 2025 are due this Friday February 28, 2025: tinyurl.com/5azetttr

Re-visiting the pathways of young people to conduct problems: later maladjustment if preceded by conduct problems, however what sets up for a lifetime persistent path of conduct problems is hard to define: tinyurl.com/y3rcawxm

Externalising polygenic score can tell something about direct genetic effects for conduct problems and ADHD symptoms across development, but less for CU traits: tinyurl.com/h4wk8dzh

Promising new treatment for antisocial personality - potentially relevant for psychopathy: Mentalisation-based treatment (originally developed for borderline personality, rooted in attachment theory, addressing early life trauma): tinyurl.com/ycxc5vsk

This is interesting: those higher on psychopathy (specifically self-centered impulsivity) show less physical distance overestimation than others - and emotional facial expressions don't have an impact if task irrelevant: tinyurl.com/mw3v46nt

Our new paper led by Aaron Hissey shows in a large longitudinal sample of couples that psychopathic personality traits are related to lower relationship satisfaction in their partner and their own professional satisfaction, but not their partners' professional satisfaction: tinyurl.com/3wjkmu8w

Psychopathic traits found to be associated with more revenge and lower benevolence motives, and feeling less forgiving towards their partners: tinyurl.com/syz4ftax

Using a foraging task, behavioural and neurophysiological measures to model learning related to psychopathic traits: differential effects of the different aspects of psychopathy and learning behaviour shows relevance of individualized rewards and punishment: tinyurl.com/2wh9carn

A busy week for #SAMBAlab! Our paper on the role of pain sensitivity in empathy for pain in psychopathy is out: nature.com/articles/s41... 🧠 We found that people with certain high psychopathic traits feel less pain (incl. physical) which predicts lower empathy for others' pain

Psychopathic traits and executive functioning found predictive for violent and property crime in youth, but together increase risk for property crime only - based on the pathways to desistance study: tinyurl.com/3e564tps

Informal social control like family and intimate relationships, living arrangements, employment and skills can mitigate (statistically mediate) the negative effect of psychopathic traits in youth on offending: tinyurl.com/ye22khme

Differentiating grandiose-manipulative and and daring-impulsive traits in addition to callous-unemotional within conduct problems seems to explain variations of behavioral externalizing patterns like aggression towards human/animals, theft, destruction and rule violation: tinyurl.com/4fn4s8kh

A machine learning approach to finding neural correlates of the "dark triad" based on the SD3 questionnaire and structural scans - food for discussion! tinyurl.com/767vnupz

New special issue out in PDTRT on externalizing psychopathology. Co-led by R. Waller, E. Verona, @drlynam.bsky.social and me. psycnet.apa.org/fulltext/202... Introduction is free to download. Check it out!

The Law & Mental Health Series rings in 2025 this Tuesday (11am MT): Cortney Simmons will be discussing how adverse environments impact youth antisocial behavior & psychopathic traits. #PsychLaw Free webinar, Free CEUs! hsc-unm.zoom.us/webinar/regi...

We are excited to announce that the SSSP Early Career Event, our virtual biannual conference for students and early-career professionals, will be held May 7-9, 2025! Abstract submissions are now live and are due February 28, 2025. universityofalabama.az1.qualtrics.com/jfe/form/SV_0V…

Thank you to Drs. Marti Erickson and Erin Erickson of the @momenough.bsky.social podcast for hosting a great conversation about Callous-Unemotional Traits in Young Children: Risk Factors & Promising Interventions www.momenough.com/2025/01/call...

New meta-analysis including 166 effect sizes shows psychopathy to be significantly related to lower task performance, less organizational citizenship behavior and more counterproductive work behavior, all most pronounced for secondary psychopathy: tinyurl.com/266rpbny

Lower HR correlated with callous psychopathic traits during social stressor task, and less cardiac adjustment to unexpected blasts in countdown task correlated with impulsive psychopathic traits in a student sample: tinyurl.com/3kftsbnv
