Results showed enhanced prefrontal recruitment with increasing task difficulty in both groups, even before movement onset.
However, for large tasks the computational load increases rapidly for increasing task length.
In addition, learning to ride a unicycle may also constitute an ecologically highly valid approach to improve balancing ability, therewith increasing task commitment and training motivation.
Figure 4: Brain regions showing decreased Hurst exponent (H) going from run-2 to run-1 of a task (increasing task novelty).
The fMRI data revealed activation increases with increasing task difficulty in pre-SMA, left putamen, and right IFG/insula.
The development of the matrix approach reflects the need for organizations in a number of public and private spheres to adapt to increasing task and environmental complexity.
Nearly a third of the list came from foreign sources, meaning Sara Lee, along with many large food companies, faces the increasing task of ensuring that foreign suppliers meet the best possible safety standards.
Furthermore, the design enabled us to reduce potential differences in memory strength between item and associative memory by increasing task difficulty in the item recognition memory test.
In addition, increasing task complexity was correlated with activity in the left anterior prefrontal cortex, a region supposed to be specifically involved in third-order higher cognitive functioning.
This design allowed to compare brain activities related to increasing task difficulty within the same group, and the two groups on the same task.
However, for large tasks the computational load increases rapidly for increasing task lengths, compared to the low computational load associated with so-called frequency domain ILC designs.
