Inhalt
- Participants.
- Table 1 Mean rating data on intensity (1 to 7), arousal (1 to 9) and valence (1 to 9) with respect to facial and vocal stimuli employed in the present study.
- Figure 1 Each condition was presented in one block, consisting of ten trials.
- Results
- Table 2 Mean accuracy in percent and response times (RTs) in milliseconds for each experimental condition.
- Discussion
- Figure 2 Enhanced activation in the right amygdala (x = 25, y = −4, z = −10) as a function of stimulus arousal for visual and auditory stimuli (CBP-corrected statistical map, initial voxel-level threshold p = 0.
- Table 3 Significant activations modelled by the parametric arousal effect irrespective of visual and auditory modalities.
- Figure 3 Significant activation cluster in posterior superior temporal sulcus (x = 48, y = −53, z = 18) as revealed by arousal contrast weights and significant activation clusters in medial superior temporal sulcus (x = 54, y = −16, z = 6) and fusiform gy
- Table 4 Significant activations modelled by the parametric interaction of arousal and modality.
