Callous-unemotional (CU) traits predict behavioral problems in adolescence. But little is known about early modulatory factors. Behavioral Inhibition (BI) particular has been suggested to protect against the development of CU-traits. This temperamental predisposition characterized by heightened environmental sensitivity. The current prospective longitudinal study examined whether BI at 15 month...

To provide an extended assessment of the affective features of psychopathy, Frick developed the Inventory of Callous and Unemotional Traits (ICU), which is a multi-informant questionnaire. Previous studies have provided initial support for the self-report version. The aim of the present study is to investigate the validity of self- as well as other report versions of the ICU and examine associa...

Reported findings on cortisol reactivity to stress in young people with ADHD are very variable. This inconsistency may be explained by high rates of comorbidity with Conduct Disorder (CD). The present study examined cortisol responses to a psychosocial stressor in a large sample of adolescent males with ADHD (n=202), with or without a comorbid diagnosis of Conduct Disorder (CD). Associations be...

The association between psychopathic traits and conduct problems has been extensively analyzed, with results showing a significant predictive effect of on later problems. However, some recent research evidenced reversed effects, early-onset also traits. present study aimed to examine the longitudinal effects (i.e., autoregressive, direct, bidirectional) three psychopathy dimensions interpersona...

BACKGROUND How is the perception of collaboration influenced by individual characteristics, in particular high levels of callous-unemotional (CU) traits? CU traits are associated with low empathy and endorsement of negative social goals such as dominance and forced respect. Thus, it is possible that they could relate to difficulties in interpreting that others are collaborating based on a share...

BACKGROUND Problems in understanding other people's mental states may relate to distinct personality traits that are associated with early externalizing behavior. A distinction between theory of mind (ToM) and empathy has proven important in shedding light on the problems in understanding other minds encountered by children high on callous-unemotional (CU) traits and exhibiting impulsivity. The...

Developmental research suggests that adolescents may be highly influenced by their peers to take risks. Although youths with callous-unemotional (CU) traits engage in high-risk behaviors in the form of antisocial behavior and aggression, little is known about their decision making, particularly when their peers are present. Youths high on CU traits may be most susceptible to influence, especial...

We evaluate the importance of callous-unemotional (CU) traits as a personality construct in isolation from other facets of psychopathy. Specifically, we review research suggesting that these traits are useful for designating a subgroup of youth with serious conduct problems who differ from other antisocial youth on important biological, emotional, cognitive, and social characteristics. In addit...
