In each of these experiments, we vary task difficulty and environmental fluctuation.
Approaches that seek to vary task features effectively consider a reciprocal type of interaction, i.e., intertwined person and task, as a form of construct irrelevant variance to be controlled for, if it cannot be avoided.
It is also easy to vary task difficulty by altering the interval between sample and test.
Movement preparation was studied with a motor priming paradigm, which varied task complexity and amount of advance information.
To explore this possibility, we collected data from an attentional control task that systematically varied task demands across separate blocks by requiring the inhibition of distracting stimuli, shifting between attentional foci, or both (Hedden and Gabrieli 2010).
Furthermore, differential results in the Sudoku and text studying task confirm that SRL can vary across tasks and domains.
Here f represents the structure of the task and μ the relevant parameters which vary across tasks.
However, reliability would likely need to be redefined as we expect performance could substantially vary over tasks that have been designed to measure the same construct given the unique interaction between person and task each assessment situation would represent.
The pragmatic skills of persons with traumatic brain injury seem to vary across tasks: these individuals have specific strengths and weaknesses in different domains.
Note that the respective studies vary in tasks, regions of interests and model of connectivity.
It is therefore recommendable that office employees vary their tasks regularly – even if the workstation guarantees a high ergonomic standard.
