This model was based on influential work by Todorov and Jordan (2002, 2004), who showed the selective use of sensory feedback to correct deviations that interfere with task goals could account for several unexplained effects in motor control, such as the variability of task-irrelevant movement qualities.
The observed variability of tasks, subtasks and their order of performance between and within units is also consistent with other studies [ 37, 38], however, few studies compare the tasks and subtasks performed during medication reconciliation in the different hospital units.
In this manuscript, Santos et al. investigated whether variability of specific task parameters are reduces during learning, and whether such reduction is mediated by neuronal activity in corticostriatal circuits.
To evaluate the within-subject variability of repeated task-induced blood flow velocity (BFV) change, we measured the haemodynamics of the anterior and middle cerebral arteries of the same volunteer on 20 consecutive working days during the performance of mental arithmetic with transcranial Doppler ultrasonography.
In the absence of adequate pilot data on the length and variability of individual tasks, calculations under several different assumptions are presented in table 1.
This article reviews motor control theories and factors influencing movement execution, and indicates how intrinsic movement variability is part of task completion.
Third, we adjusted task difficulty according to developmental ability, to reduce variability of in-scanner task performance and effort.
Our results are in agreement with these previous findings, as increased activity in these two regions were related to the highest rate of attention directed toward the SART, both subjectively with thought-probe reports and objectively with task performance (i.e., less errors and less variability of RTs for task-related reports).
In an intratest analysis, both in GI and GII, lower scores and higher variability of responses in tasks involving phonemic awareness can be observed when compared to tasks involving syllabic awareness.
Due to the complexity and variability of relationship between tasks and resources in the vehicle sensing system, the resources are held or requested by multitasking, which may lead to deadlocks.
