Brain imaging studies of adults with psychopathy have identified structural and functional abnormalities in limbic and prefrontal regions that are involved in emotion recognition, decision-making, morality and empathy. Among children with conduct problems, a small subgroup presents callous-unemotional traits thought to be antecedents of psychopathy. No(More)
BACKGROUND   Empathy dysfunction is one of the hallmarks of psychopathy, but it is also sometimes thought to characterise autism spectrum disorders (ASD). Individuals with either condition can appear uncaring towards others. This study set out to compare and contrast directly boys with psychopathic tendencies and boys with ASD on tasks assessing aspects of(More)
OBJECTIVE Although early-onset conduct problems predict both psychiatric and health problems in adult life, little research has been done to index neural correlates of conduct problems. Emerging research suggests that a subgroup of children with conduct problems and elevated levels of callous-unemotional traits may be genetically vulnerable to manifesting(More)
CONTEXT Genetic vulnerability to psychopathic traits is likely to also manifest at the neural level. We have recently reported increased gray matter concentration in several brain areas in boys with psychopathic traits. OBJECTIVE To explore whether these gray matter concentration differences can be regarded as endophenotypes for psychopathic traits by (1)(More)
A previous finding from our group indicated that teacher-rated antisocial behaviour (AB) among 7-year-olds is particularly heritable in the presence of callous-unemotional (CU) traits. Using a sample of 1865 same-sex twin pairs, we employed DeFries-Fulker extremes analysis to investigate whether teacher-rated AB with/without CU traits also shows(More)
Although a single diagnostic label, conduct disorder, is currently applied to children exhibiting antisocial behaviour, multiple routes to the same behavioural phenomena exist. Morton and Frith's (1995) causal modelling has been fundamentally important in influencing models of cognitive/affective and associated neural differences between callous-unemotional(More)
Using combined miniature archival light and salt-water immersion loggers, we characterise the year-round individual at-sea movements of Europe's only critically endangered seabird, the Balearic shearwater Puffinus mauretanicus, for the first time. Focusing on the non-breeding period, we show that all of the 26 breeding birds tracked from their breeding site(More)
AIM This small study was designed to assess the nature and severity of social-cognitive deficits in antisocial adolescents. METHOD Thirty-seven boys aged 15-18 from a Young Offenders Institute and Community College participated. They were asked to complete a test of general intellectual ability and self-rating of social competence as well as tasks from(More)
As many as six in every 1000 children may be affected by an autistic spectrum disorder. Characterised by a triad of social communication difficulties, these children exhibit impairment in communication and socialisation, and restricted and repetitive interests, movements and activities. This article will discuss the distinction between autism, Asperger's(More)
