Statistical analyses performed on the mean area amplitude of posterior N2 (attentional selection negativity) showed that the attention condition was highly significant (F [3,75] = 16.06, GG adjusted p < 0.000059) with larger negativities to pseudo-targets than stimuli sharing only space location with the targets, and to the latter than to non-targets (see mean amplitude values in Figure 4).
Although older adults were less attentive to negative stimuli in the full attention condition, they could not avoid the negative stimuli in the divided attention condition, and the outcome reversed: older adults attended more to negative stimuli when they were distracted [ 15].
During the joint attention condition compared with the other conditions, 4 6 Hz frontal, central, and parietal power was lowest, indexing greater neural activation.
The group with schizophrenia showed a significant improvement in accuracy on a digit span repetition task when a simultaneous box-crossing task was added (divided attention condition).
Additionally, subjects with ASD showed less deactivation in medial prefrontal cortex (part of the default mode network) in the globally directed attention condition.
In 6 9 Hz, the pattern was consistent with 4 6 Hz findings for the frontal region such that 6 9 Hz frontal power was lower, indexing greater neural activation, in the joint attention condition compared with the nonsocial condition.
Here, we were interested in the functional connectivity of the midbrain during the performance of the sustained attention condition of the drug-word task, not during resting-conditions.
A comparison of the two auditory task conditions (UA and BA) revealed larger AOAs during the unimodal auditory attention condition when no visual stimuli were present (F 1,8) = 8.86, p<0.02) suggesting that unattended visual stimuli inhibited AOA responses.
Participants started with the divided attention condition for both letters and shapes to avoid any priming effects of the focused attention condition on the divided attention condition.
In the focused attention condition, participants completed two runs.
Global advantage was significantly larger for letter stimuli than for shape stimuli and for the focused attention condition than for the divided attention condition.
