Correlations of the mental workload scores with the usability scores by performance class.

Activations from significant clusters for contrast 2-back>0-back and 0-back>2-back (t-contrast). Activations were thresholded at a whole-brain FWE corrected p < 0.05 with an...

The analysis of the responses showed that almost over 90% of the tactile stimuli were assigned correctly (N = 24).

Activations were thresholded at a whole-brain FWE corrected p< 0.05 with an extent threshold of 20 voxels. The MNI Coordinates are the same as peak voxel locations.

The table shows the mean cardiovascular responses by the modafinil and the placebo group. Compared to placebo, modafinil had no statistically significant effect on pulse,...

Pearson and Spearman correlation coefficients of the usability and the mental workload scores.

Note. The cluster-wise threshold (correct p<.048) is determined by voxel-wise threshold (p<.005) and the minimum volume (53 contiguous voxels; 424 mm3). Results of the...

Participants were significantly slower in their response (RT) under 2-back than under 0-back. Similarly, ER was significantly lower under 0-back than under 2-back. There was no...
