A widely used tool for functional magnetic resonance imaging (fMRI) data analysis, statistical parametric mapping (SPM), is based on the general linear model (GLM). SPM therefore requires a priori knowledge or specific assumptions about the time courses contributing to signal changes. In contradistinction, independent component analysis (ICA) is a(More)
BACKGROUND It is important to understand which factors increase the risk of posttraumatic stress disorder (PTSD) in adolescents. Previous studies have shown that the most important risk factors for PTSD include the type, severity, and duration of exposure to the traumatic events. METHODS A cross-sectional survey was used to investigate the psychological(More)
The current study investigated the time course of the affective processing bias in major depressive disorder (MDD) in a visual three-stimulus semantic oddball task using event-related potentials (ERPs). MDD patients showed decreased P1 latency over right posterior regions to negative relative to positive target stimuli, reflecting a very early onset of the(More)
The relationship between symptoms of schizophrenia and abnormalities in the P300 component of the event-related potential (ERP) was investigated in 22 and 27 patients diagnosed with positive and negative profile schizophrenia, respectively. The Positive and Negative Syndrome Scale (PANSS) was used to characterize clinical symptoms. A group of 30 normal(More)
The current study explored the music perception ability of individuals diagnosed with schizophrenia and its relationship with other cognitive abilities and psychotic symptom severity. The persons with schizophrenia performed significantly worse than the control group on the Montreal Battery of Evaluation of Amusia (MBEA) (p<0.001). The music perception(More)
Ample evidence from functional magnetic resonance imaging studies has demonstrated functional brain asymmetries in the motor cortex and cerebellum within the task of finger-to-thumb (intratask), but the asymmetries across left and right hand-performed tasks of finger-to-thumb (intertask) are little known. Here, we found that intratask evoked asymmetry(More)
Functional Magnetic Resonance Imaging (fMRI) of inhibitory control has only been investigated in patients with attention deficit hyperactivity disorder (ADHD) and conduct disorder (CD). The objective of this study was to investigate the differences of functional areas associated with inhibitory control between boys with pure oppositional defiant disorder(More)
Functional connectivity among brain regions has been widely researched in terms of spatial maps or between-region connectivity strengths. Yet it is not easy to interpret the results of such research. In this paper, a pattern analysis framework based on the general linear model and the fuzzy c-means clustering algorithm is presented. This schema is applied(More)
The English items of Gambling Related Cognitions Scale (GRCS) were first developed and validated by community-based population in 2004. The scale is now becoming a validated and reliable instrument to assess gambling related cognitions in the gambling literature of the West. The present study recruited 730 general adult Chinese individuals to validate the(More)
