Previous research suggests that face recognition may involve both configurational and piecemeal (featural) processing. To explore the relationship between these processing modes, we examined the patterns of recognition impairment produced by blurring, inversion, and scrambling, both singly and in various combinations. Two tasks were used: recognition of(More)
OBJECTIVE Child abuse is an important risk for adult psychiatric morbidity. However, not all maltreated children experience mental health problems as adults. The aims of the present study were to address the extent of resilience to adult psychopathology in a representative community sample, and to explore predictors of a good prognosis. METHODS Data are(More)
Background: The Malaise Inventory is a commonly used self-completion scale for assessing psychiatric morbidity. There is some evidence that it may represent two separate psychological and somatic sub-scales rather than a single underlying factor of distress. This paper provides further information on the factor structure of the Inventory and on the(More)
BACKGROUND Existing evidence points to a substantial rise in psychosocial disorders affecting young people over the past 50 years (Rutter & Smith, 1995). However, there are major methodological challenges in providing conclusive answers about secular changes in disorder. Comparisons of rates of disorder at different time points are often affected by changes(More)
BACKGROUND Alterations in reward processing may represent an early vulnerability factor for the development of depressive disorder. Depression in adults is associated with reward hyposensitivity and diminished reward seeking may also be a feature of depression in children and adolescents. We examined the role of reward responding in predicting depressive(More)
This study addressed the basis for the intergenerational transmission of psychosocial risk associated with maternal childhood abuse in relation to offspring adjustment. The study tested how far group differences in individual change in adjustment over time were explained by differences in exposure to specific environmental risk experiences. Data are drawn(More)
Research suggests that inverted faces are harder to recognise than upright faces because of a disruption in processing their configural properties. Reasons for this difficulty were explored by investigating people's ability to identify faces at intermediate angles of rotation. Participants were asked to discriminate blurred famous and unfamiliar faces(More)
To describe and validate the ‘DAWBA bands’. These are novel ordered-categorical measures of child mental health, based on the structured sections of the Development and Well-Being Assessment (DAWBA). We developed computer algorithms to generate parent, teacher, child and multi-informant DAWBA bands for individual disorders and for groups of disorder (e.g.(More)
Past studies have documented rising levels of conduct problems among UK adolescents in the last quarter of the twentieth century, and increased rates of emotional difficulties between the 1980s and 1990s. We used parent, teacher and youth ratings from two large scale, nationally representative studies of 5–15 year-old carried out in 1999 and 2004 to assess(More)
Using psychophysics we investigated to what extent human face recognition relies on local information in parts (featural information) and on their spatial relations (configural information). This is particularly relevant for biologically motivated computer vision since recent approaches have started considering such featural information. In Experiment 1 we(More)
