Objective: In this review, we examined if there is a deficit in facial recognition of emotion (FER) in children, adolescents, and adults with attention deficit hyperactivity disorder (ADHD). Background: Emotional regulation is impaired in ADHD. Although a facial emotion recognition deficit has been described in this condition, the underlying…

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were…

Adolescence is a period in everybody's life that is usually referred to as "time that everybody must go through" or "parents' hell". Transition between childhood and adulthood is indeed of great importance in everybody's life, but it is usually accompanied with a variety of questions, problems, dilemmas and a constant need to…

This study examined two main questions: (1) Is there a direct link between psychopathic traits and intelligence? (2) Is the combination of psychopathic traits and high IQ related to more severe antisocial behaviour in adolescents?

Objective: To test whether the Adult Self-Report Scale for ADHD, six-items version (ASRS-6), measures inattentiveness and hyperactivity independently. Method: The ASRS-6 was completed by 234 university students and 157 outpatients treated for drug dependence. In both samples, the ASRS-6 was subjected to two confirmatory factor analyses, one…

This study investigates whether low to moderate levels of childhood oppositional defiant disorder (ODD) and conduct disorder (CD) behaviors contribute to the development of clinically diagnosed CD in adolescence, in children with attention deficit hyperactivity disorder (ADHD). Participants were 207 White boys (ages 6-12) with ADHD free of conduct…

While hyperactivity in children has been alternately viewed as a form of minimal brain dysfunction, as a behavior disorder, or as an attention deficit disorder, recent findings on hyperactive adolescents and adults suggest that hyperactivity can be better understood as a personality disorder. Striking similarities appear when characteristics of…

Background: Boys with early onset of conduct disorder (CD), most of whom also meet diagnostic criteria of a comorbid attention deficit hyperactivity disorder (ADHD), tend to exhibit high levels of aggression throughout development. While a number of functional neuroimaging studies on emotional processing have been performed in antisocial adults,…

Administered Minnesota Multiphasic Personality Inventory (MMPI) to biological mothers of children aged 6-13 (N=100). Found conduct disordered (CD) children (N=13) had mothers with higher MMPI antisocial, histrionic, and disturbed adjustment scores; attention deficit disorder with hyperactivity (ADD/H) children (N=22) had no significant association…

This case study examines the effects of neurofeedback (EEG biofeedback) training on affect regulation in a fifty-five year-old man with a history marked by fear, rage, alcoholism, chronic unemployment and multiple failed treatments. He had been diagnosed with ADHD and attachment disorder and met criteria for anti-social personality disorder. The…

Comorbidities among children with ADHD are key determinants of treatment response, course, and outcome. This study sought to separate family factors (parental psychopathology and parenting practices) associated with comorbid Oppositional Defiant Disorder (ODD) from those associated with Conduct Disorder (CD) among children with Attention…

It is essential to identify childhood predictors of adult antisocial personality disorder (APD) to target early prevention. It has variously been hypothesized that APD is predicted by childhood conduct disorder (CD), attention-deficit/hyperactivity disorder (ADHD), or both disorders. To test these competing hypotheses, the authors used data from a…

While minor physical anomalies (MPAs), a set of 17 non-obvious but measurable characteristics of the hands, face and feet, have been linked to a number of behavioral syndromes in children, such personality correlates of MPAs in adults have not been studied. To explore the relationshp between MPAs and temperament in a college sample, 114 students…

Objective: To compare the pattern of familial aggregation of psychopathology in children who are good responders (GR) to methylphenidate (MPH) versus those who are poor responders (PR). Method: A total of 118 clinically referred children ages 6 to 12 years, diagnosed with ADHD participated in a double-blind, placebo-controlled, randomized 2-week…
