Lighter icon color and more difficult task requirement generated worse task performance but had limited impact on cervical spine biomechanics.
During the executive task, PD patients showed weaker BG-cortical connectivity than controls, i.e., between caudate-supramarginal gyrus and pallidum-inferior prefrontal regions, that was related to more severe PD symptoms and worse task performance.
During rest, stronger putamen-medial parietal and pallidum-occipital connectivity in PD than controls was associated with worse task performance and more severe PD symptoms suggesting that abnormalities in resting-state connectivity denote neural network dedifferentiation.
However, the proportion of time females spent facing the better performer was not predicted by the magnitude of difference in performance between the better and worse task performer in the No-Interaction tests (linear mixed-effects model, difference in performance: 0.009±0.023, t46 = 0.397, P = 0.693), nor in the Interaction tests (0.004±0.015, t85 = 0.236, P = 0.814).
Their results indicate that the experimental group showed worse task performance.
Longer protocols may have caused fatigue in patients, resulting in worse task performance.
Under Fluoxetine, mPFC activation was up-regulated and normalized in ASD boys relative to controls, but down-regulated in ADHD boys relative to placebo, which was concomitant with worse task performance in ADHD.
They conceded that their change blindness trials might have included more trials from sequences with worse task preparation as compared to trials in which participants correctly reported the absence of change, as this could have resulted in the kind of differences in ERPs they observed.
However, comparing performance at visit 1 between PCA and tAD patients revealed that the PCA group performed significantly better on the verbal memory task (P <.001) and arithmetic (P =.01), whereas performance in the PCA group was significantly worse on tasks of visuospatial processing (P =.01) and the letter cancellation task (P =.02) compared with the tAD group.
Following 24-hour placebo (versus nicotine) administration, accuracy on the N-back task was significantly worse and task-related BOLD signal lower in dorsomedial frontal cortex.
