Salivary cortisol and psychopathy dimensions in detained antisocial adolescents.

Unlabelled: Previous research revealed hypothalamic-pituitary-adrenal (HPA) axis abnormalities in relation to antisocial and aggressive behavior. Some evidence suggests that low cortisol levels may serve as a biological marker for a severe antisocial subgroup with pronounced callous-unemotional (CU) traits. Children displaying the combination of severe antisocial behavior and CU traits appear to be particularly at risk of developing adult psychopathy.

Knowing right from wrong, but just not always feeling it: relations among callous-unemotional traits, psychopathological symptoms, and cognitive and affective morality judgments in 8- to 12-year-old boys.

The present research expands our understanding of cognitive and affective morality by exploring associations with callous-unemotional (CU) traits and externalizing symptoms. Participants were 46 8- to 12-year-old boys from the community who completed the Affective Morality Index, the Youth Self-Report, and the Inventory of Callous-Unemotional Traits. A pattern of results was found indicating that in particular the combination of high CU traits and high externalizing symptoms was associated with lack of affective morality, and an increased perceived likelihood of recommitting antisocial acts (recidivism).

Youth psychopathy: Differential correlates of callous-unemotional traits, narcissism, and impulsivity.

Research supports the validity of the dimensional approach to psychopathy in both children and adults. The occurrence of severe aggressive and antisocial behavior in combination with callous-unemotional traits (CU traits) designates a group of children that is particularly at risk to develop psychopathy. However, most studies did not investigate the role of the remaining psychopathy dimensions (i.

Assessing Callous-Unemotional traits across different groups of youths: further cross-cultural validation of the Inventory of Callous-Unemotional traits.

The Inventory of Callous-Unemotional (CU) Traits (ICU) is a self-report questionnaire which was developed to measure the affective features of psychopathy in children and adolescents. Previous studies reported both support and difficulties with this promising new measure. The present study investigated the psychometric and discriminating qualities of the Dutch questionnaire across different groups by examining its structure, distribution and correlates.

Differential associations between psychopathy dimensions, types of aggression, and response inhibition.

Findings on executive functioning in psychopathy are inconsistent. Different associations between psychopathy dimensions and executive functioning might explain contradicting findings. This study examined the role of psychopathy dimensions and types of aggression in response inhibition among 117 male adolescents (53 antisocial delinquents and 64 controls).

Differential effects of endogenous lithium on neurobehavioural functioning: a study on auditory evoked potentials.

Lithium occurs naturally in food and water. Low environmental concentrations in drinking water are associated with mental illnesses and behavioural offences, and at therapeutic dosages it is used to treat psychiatric (especially affective) disorders, partly by facilitating serotonergic (5-HT) neurotransmission. As little is known about the psychophysiological role of nutritional lithium in the general population, endogenous lithium concentrations were hypothesised to be associated with measurable effects on emotional liability and the loudness dependence (LD) that is proposed as one of the most valid indicators of 5-HT neurotransmission.
