This article introduces a novel hypothesis regarding amygdala function in psychopathy. The first part of this article introduces the concept of psychopathy and describes the main cognitive and affective impairments demonstrated by this population; that is, a deficit in fear-recognition, lower conditioned fear responses and poor performance in passive(More)
Child conduct problems (CPs) are a robust predictor of adult mental health; the concurrence of callous-unemotional (CU) traits confers specific risk for psychopathy. Psychopathy may be related to disturbances in the oxytocin (OXT) system. Evidence suggests that epigenetic changes in the OXT receptor gene (OXTR) are associated with lower circulating OXT and(More)
BACKGROUND A propensity to attend to other people's emotions is a necessary condition for human empathy. AIMS To test our hypothesis that psychopathic disorder begins as a failure to attend to the eyes of attachment figures, using a `love' scenario in young children. METHOD Children with oppositional defiant disorder, assessed for callous-unemotional(More)
BACKGROUND The serotonin system is thought to play a role in the aetiology of antisocial and aggressive behaviour in both adults and children however previous findings have been inconsistent. Recently, research has suggested that the function of the serotonin system may be specifically altered in a sub-set of antisocial populations - those with psychopathic(More)
OBJECTIVES The involvement of arginine-vasopressin (AVP) in animal and human aggression has been well established in the literature. Recent research has shown an association between the minor allele (C) of single-nucleotide polymorphism rs35369693 located on the AVP 1B receptor gene and childhood aggression. MATERIALS AND METHODS The present study sought(More)
The co-occurrence of child conduct problems (CPs) and callous-unemotional (CU) traits confers risk for psychopathy. The oxytocin (OXT) system is a likely candidate for involvement in the development of psychopathy. We tested variations in the OXT receptor gene (OXTR) in CP children and adolescents with varying levels of CU traits. Two samples of Caucasian(More)
The Social Responsiveness Scale (SRS) is a well-established measure of autism spectrum disorder (ASD), yet it is known to suffer reduced specificity in samples of children with comorbid emotional or behavioural problems. This research examined the specificity of the SRS in children with mixed presentations of internalising and externalising psychopathology(More)
In accordance with a recently proposed account of amygdala function in psychopathy, it is hypothesized that people with high levels of psychopathic personality traits have a bias in learning style to encode the general valence, and neglect the specific-features, of an outcome. We present a novel learning task designed to operationalize these biases in(More)
The co-occurrence of conduct problems (CPs) and high callous-unemotional (CU) traits specifies risk for adult psychopathy and is under a high genetic influence. A previous genome-wide pooled DNA study of 7-year olds identified a set of candidate single-nucleotide polymorphisms (SNPs) that might differentiate high CP+CU children from healthy children. We(More)
There is considerable interest in the pharmacogenetics of responses to stimulant treatment for attention-deficit/ hyperactivity disorder (ADHD) (Froehlich et al. 2010). By contrast, little attention has been paid to individual differences in side effects. Dopamine function in the prefrontal cortex (PFC) is a strong candidate system for understanding these(More)
