This event-related fMRI study examined the impact of processing load on the BOLD response to emotional expressions. Participants were presented with composite stimuli consisting of neutral and fearful faces upon which semi-transparent words were superimposed. This manipulation held stimulus-driven features constant across multiple levels of processing load.(More)
We examined the impact of witnesses on the neural response to moral and social transgressions using fMRI. In this study, participants (N=16) read short vignettes describing moral and social transgressions in the presence or absence of an audience. In line with our hypothesis, ventrolateral (BA 47) and dorsomedial (BA 8) frontal cortex showed increased BOLD(More)
Transient reductions in serotonin levels during tryptophan depletion (TD) are thought to impair reward processing in healthy volunteers, while another facet of the serotonergic system, the serotonin transporter (5-HTTLPR) short allele polymorphism, is implicated in augmented processing of aversive stimuli. We examined the impact and interactions of TD and(More)
First admission rates to the psychiatric hospital in Kuwait revealed that foreign housemaids as a whole had about five times the rate of Kuwaiti females. According to hospital diagnoses the housemaids had significantly more acute situational disturbances and mania, and less depressive illness and organic mental disorders. Regarding schizophrenia and(More)
