Attentional modulation of emotional stimulus processing: an fMRI study using emotional expectancy.
We used emotional expectancy to study attentional modulation in the processing of emotional stimuli. During functional magnetic resonance imaging (fMRI), volunteers saw emotional and neutral expectancy cues signaling the subsequent presentation of corresponding emotional or neutral pictorial stimuli. As a control, emotional and neutral pictures were presented without preceding expectancy cue, r...
متن کاملAttentional modulation of emotional stimulus processing in patients with major depression--alterations in prefrontal cortical regions.
Patients with depression show an impaired ability to modulate emotional states and to process positive emotional information. Here we examined expectancy-induced modulation of emotional picture processing in major depression. We hypothesized alterations in the medial prefrontal cortex. During fMRI, 15 depressed and 21 healthy control subjects passively viewed affective photographs. Half of the ...
متن کاملEmotional Picture and Word Processing: An fMRI Study on Effects of Stimulus Complexity
Neuroscientific investigations regarding aspects of emotional experiences usually focus on one stimulus modality (e.g., pictorial or verbal). Similarities and differences in the processing between the different modalities have rarely been studied directly. The comparison of verbal and pictorial emotional stimuli often reveals a processing advantage of emotional pictures in terms of larger or mo...
متن کاملImplicit and Explicit Attention to Pictures and Words: An fMRI-Study of Concurrent Emotional Stimulus Processing
The present study utilized functional magnetic resonance imaging (fMRI) to examine the neural processing of concurrently presented emotional stimuli under varying explicit and implicit attention demands. Specifically, in separate trials, participants indicated the category of either pictures or words. The words were placed over the center of the pictures and the picture-word compound-stimuli we...
متن کاملAttentional Modulation of Emotional Conflict Processing with Flanker Tasks
Emotion processing has been shown to acquire priority by biasing allocation of attentional resources. Aversive images or fearful expressions are processed quickly and automatically. Many existing findings suggested that processing of emotional information was pre-attentive, largely immune from attentional control. Other studies argued that attention gated the processing of emotion. To tackle th...
