This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health(More)
There have been suggestions that Theory of Mind (ToM) impairment might lead to aggressive behaviour and psychopathy. Psychopathic and matched non-psychopathic individuals, as defined by the Hare Psychopathy Checklist [The Hare Psychopath Checklist-Revised, 1991] completed the 'Reading the Mind in the Eyes' ToM Test [Journal of Child Psychology and(More)
The impact of emotional stimuli on a simple motor response task in individuals with psychopathy and comparison individuals was investigated. Psychopathy was assessed using the Psychopathy Checklist Revised (Hare, 1991). Participants were presented with the Emotional Interrupt Task, in which they responded with left and right button presses to shapes that(More)
The processing of emotional expressions is fundamental for normal socialization and interaction. Reduced responsiveness to the expressions of sadness and fear has been implicated in the development of psychopathy (R. J. R. Blair, 1995). The current study investigates the ability of adult psychopathic individuals to process vocal affect. Psychopathic and(More)
Frontal lobe and consequent executive dysfunction have long been related to psychopathy. More recently, there have been suggestions that specific regions of frontal cortex, rather than all of frontal cortex, may be implicated in psychopathy. To examine this issue, the authors presented 25 individuals with psychopathy and 30 comparison individuals with(More)
BACKGROUND The value of histological grading was examined with emphasis on reliability of assessment in 102 cases of intraoral squamous cell carcinoma from Northern Ireland with known outcome. METHODS Two pathologists independently graded the invasive tumour front blinded to the stage and outcome. RESULTS Intraobserver agreement was acceptable but(More)
Five cases of abdominal wall reconstruction using the tensor fasciae latae myocutaneous flap are described. This flap provides a deep layer of tissue of sufficient strength to prevent herniation and external cover in a single stage repair. We regard it as the method of choice in the reconstruction of major defects of the abdominal wall.
Accurate histologic determination of lymph node metastasis is most important in predicting prognosis in patients who undergo radical neck dissection. In this study of 340 determinate patients, the five year survival was 75 per cent when lymph nodes were histologically negative, 49 per cent when one lymph node was positive, 30 per cent when two lymph nodes(More)
Tumours of the oral cavity/oropharynx occur relatively infrequently in the UK. The management of such lesions, especially the squamous cell carcinomas, is still a little controversial. Some centres advocate radiotherapy while others adopt surgery and radiotherapy. In an attempt to resolve the question of which approach gives the better results, a(More)
Previous work has indicated dysfunctional affect-language interactions in individuals with psychopathy through use of the lexical decision task. However, it has been uncertain as to whether these deficits actually reflect impaired affect-language interactions or a more fundamental deficit in general semantic processing. In this study, we examined affective(More)
