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)
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 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)
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)
BACKGROUND Perceived educational environment influences academic outcomes, such as academic achievement, students' behaviors, well-being, socio-emotional adjustment and explicit self-esteem. Mindfulness is a set of skills that are beneficial to physical and mental health. Recently, it has been increasingly discussed about its usefulness in education, but(More)
BACKGROUND Given the increasing elderly population worldwide, the identification of potential determinants of successful ageing is important. Many studies have shown that parenting style and mental resilience may influence mental health; however, little is known about the psychological mechanisms that underpin this relationship. The current study sought to(More)
The present study examined whether people with high gambling-related cognitive bias are more likely to have higher levels of impulsivity than are those with low gambling-related cognitive bias. We used Barratt Impulsiveness Scale version 11, Zuckerman-Kuhlman Personality Questionnaire and the Iowa gambling task to explore differences in impulsivity between(More)
BACKGROUND Congenital amusia is a disorder that is known to affect the processing of musical pitch. Although individuals with amusia rarely show language deficits in daily life, a number of findings point to possible impairments in speech prosody that amusic individuals may compensate for by drawing on linguistic information. Using EEG, we investigated (1)(More)
