Dissociable effects of bottom-up and top-down factors on the processing of unattended fearful faces.
While the role of attention in determining the neural fate of unattended emotional items has been investigated in the past, it remains unclear whether bottom-up and top-down factors have differential effects in shaping responses evoked by such stimuli. To study the effects of bottom-up and top-down factors on the processing of neutral and fearful faces, we employed functional magnetic resonance...
متن کاملEvent-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces
Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
متن کاملThe effect of bottom-up and top-down auditory program training on the development of children's auditory processing skills
Although there have been several previous investigations on the role of auditory training for the development of auditory processing skills, it still remains unknown whether children with auditory processing difficulties can get improved auditory skills after exposure to a multi-modal training experience comprising both visual and tactile stimuli. The present study, therefore, attempted to use ...
