OBJECTIVE This article describes the establishment of the Australian Schizophrenia Research Bank (ASRB), which operates to collect, store and distribute linked clinical, cognitive, neuroimaging and genetic data from a large sample of people with schizophrenia and healthy controls. METHOD Recruitment sources for the schizophrenia sample include a(More)
BACKGROUND Abnormal visual scanpaths to faces and facial expressions in schizophrenia may underlie schizophrenic subjects' disturbed interpersonal communication. This study is the first to examine the specificity of these impairments to schizophrenia, by including an affective disorder psychiatric control group. METHODS The visual scanpath performance of(More)
Previous research demonstrates that people with 22q11.2 deletion syndrome (22q11DS) have social and interpersonal skill deficits. However, the basis of this deficit is unknown. This study examined, for the first time, how people with 22q11DS process emotional face stimuli using visual scanpath technology. The visual scanpaths of 17 adolescents and(More)
Individuals with developmental disorders frequently report a range of social cognition deficits including difficulties identifying facial displays of emotion. This study examined the specificity of face emotion processing deficits in adolescents with either autism or 22q11DS compared to typically developing (TD) controls. Two tasks (face emotion recognition(More)
We used a psychophysiological marker of visual attention (the visual scanpath) to investigate the effects of atypical (risperidone) vs. typical (haloperidol) antipsychotic medication on facial emotion perception in schizophrenia (n=28) and healthy control (n=28) groups. Of the schizophrenia subjects, 15 were prescribed risperidone. Visual scanpaths to(More)
We used a psychophysiological marker of visual attention (visual scanpath) to investigate facial emotion processing in schizophrenia (n= 65) and healthy control (n = 61) groups. Visual scanpaths to 'happy', *sad' and 'neutral' faces (two exposures each) were recorded using video-oculography. Emotion recognition accuracy was assessed under both 'difficult'(More)
There is substantial evidence that schizophrenics have deficits in face processing. We hypothesised that this difficulty is due to abnormalities in the visual scanning of faces. The specificity of these abnormalities to recognisable faces, the effect of task difficulty and their relationships to three primary symptom dimensions were examined. An infrared(More)
OBJECTIVE This paper documents the establishment of the Schizophrenia Research Register of the Neuroscience Institute of Schizophrenia and Allied Disorders (NISAD). This register aims to provide a volunteer pool of people with a clinical diagnosis of schizophrenia who are willing to consider participating in research projects. This unique resource is(More)
Previous research demonstrates that people with schizophrenia have abnormally 'restricted' visual scanpaths to face and facial expression stimuli, which appear to be diagnostically specific to schizophrenia [Schizophr. Res. 55 (2002) 159; Biol. Psychiatry 52 (2002) 338]. This study examined the familial transmission of 'restricted' scanpaths in first-degree(More)
BACKGROUND This paper examines the potential impact of recruitment source differences in schizophrenia research by comparing the neuropsychological performance of volunteers from the NISAD Schizophrenia Research Register with recently published schizophrenia normative data for the Repeatable Battery for Neuropsychological Status (RBANS).
