This further supports the proposal that lesion anatomy, rather than volume, is most likely to be the crucial determinant of impairment on the task.
9 Disturbingly, lack of subjective drowsiness does not mean that an individual is able to drive a vehicle without impairment because subjective somnolence and impairment of the ability to perform tasks are not necessarily correlated.
56, 57 Behavioral investigations utilizing position matching tasks of different processing demands have shown that proprioceptive feedback processing in the human brain shows age-related impairment depending on the difficulty of the task.
The advantage of using these tasks is in their ability to cause two types of mental fatigue: After both 0-back and 2-back test sessions, impairment of task performance assessed by the percentage of correct task trials was significant, while longer reaction times and a higher subjective level of sleepiness could be identified only after the 0-back test trials.
Impairments of these tasks occur after left hemispheric brain lesions causing apraxia.
The distraction/task effect is usually explained in terms of task impairment being caused by a conflict in the processing of the task (Marsh, Hughes, & Jones, 2008).
These results suggested that, as motivation has been reported to be associated with increased sympathetic activity [ 17, 18], motivation against potential impairment of task performance caused by mental fatigue may contribute to the increased sympathetic activity observed during fatigue-inducing mental tasks.
The finding of Schmitter-Edgecombe et al. suggested that the impairment of aMCI patients in PM tasks was not the result of forgetting the content of the task instructions [ 11].
Although a regional cortical abnormality is expected to result in impairment of task performance of that region, underconnectivity of cortical regions is likely to result in impairment in the integration of tasks.
B - Task Name of the task.
