A neural adaptation paradigm where adaptor and test stimuli were presented in rapid succession was employed to investigate links between the face-sensitive N170 component and configural face processing. In Experiment 1, schematic adaptor stimuli preceded naturalistic images of upright faces, inverted faces, or isolated eyes. Relative to a baseline condition(More)
To determine the time course of face recognition and its links to face-sensitive event-related potential (ERP) components, ERPs elicited by faces of famous individuals and ERPs to non-famous control faces were compared in a task that required explicit judgements of facial identity. As expected, the face-selective N170 component was unaffected by the(More)
Stimulant medication efficacy was evaluated in 14 children with attention-deficit hyperactivity disorder and IQs of 48 to 74 in a double-blind crossover study of two methylphenidate doses and placebo. Dependent measures included behavioral ratings, work output, measures of learning, attention and impulsivity, and direct observation of peer social(More)
BACKGROUND Clinicians have many unanswered questions during clinical encounters which may impact on the quality and outcomes of decisions made. Provision of online evidence at the point of care is one strategy that provides clinicians with easy access to up-to-date evidence in clinical settings to support evidence-based decision-making. AIM To determine(More)
The adverse side effects of methylphenidate were evaluated in 27 children with attention deficit hyperactivity disorder and IQs of 48 to 74 who participated in a double-blind study of two doses of methylphenidate and placebo. A checklist of 13 side effects, generated from the Physician's Desk Reference, was completed by teachers. Rates of irritability,(More)
OBJECTIVE To investigate factors influencing variations in clinicians' use of an online evidence retrieval system. SETTING Public hospitals in New South Wales, Australia. METHOD Web log analysis demonstrated considerable variation in rates of evidence use by clinicians at different hospitals. Focus groups and interviews were held with 61 staff from(More)
Individuals with developmental prosopagnosia (DP) show severe face recognition deficits in the absence of any history of neurological damage. To examine the time-course of face processing in DP, we measured the face-sensitive N170 component of the event-related brain potential (ERP) in a group of 16 participants with DP and 16 age-matched control(More)
To study the existence and neural basis of covert face recognition in individuals with developmental prosopagnosia, we tested a group of 12 participants with developmental prosopagnosia in a task that required them to judge the familiarity of successively presented famous or non-famous faces. Electroencephalography was recorded during task performance, and(More)
OBJECTIVE To measure the impact of a state health department policy to provide allied health professional staff with access to a point-of-care, 24h, online evidence system in terms of awareness, use and clinical impact of the system on clinical practice; to identify perceived barriers to use, and differences in measures between seven professional groups(More)
OBJECTIVE To assess the impact of clinicians' use of an online information retrieval system on their performance in answering clinical questions. DESIGN Pre-/post-intervention experimental design. MEASUREMENTS In a computer laboratory, 75 clinicians (26 hospital-based doctors, 18 family practitioners, and 31 clinical nurse consultants) provided 600(More)
