Such differences in scale between different tasks do not change the significance of the curvature of the Pareto front; in fact, axes can even have different units and the meaning of the curvature will be the same (Shoval et al., 2012).
Various models have been proposed to explain such interaction: for instance the model of competition or sharing the attention resource system, the model of non-linear interaction between different tasks and the model of priority task [7], [8].
Colzato and Hommel found that, relative to a sample of cocaine-free controls, recreational users show increased costs in switching between different tasks [12] and no reliable inhibition of return (IOR) [13]-the (commonly robust) phenomenon of slowed responding when attention needs to return to a previously attended location [14].
The only significant relationship between different tasks a priori measuring different processes was observed between incapacity to terminate a chain of presses in the FCN8 task and hyperactivity during extinction periods.
Located on the frontal lobe, it is a toolbox of mental attention skills that enables the brain to concentrate on one task while blocking out competing information and to switch focus between different tasks without becoming confused.
More impressive is its ability to quickly switch between different tasks.
In conclusion, we found that individuals' metacognitive knowledge of perceptual performance remained stable across two different visual tasks, even though the individual objective performance changed substantially between different tasks.
Our hypothesis is that the same cognitive processes are utilised in the practicing of different complex laparoscopic tasks, like procedural training, and therefore these processes are transferable between different tasks.
Statistical results of correlation analysis between scores obtained in the different tasks of impulsivity are summarized in table 2. Whereas several of the variables measured within the same task were correlated, only a few inter-task correlations were found.
Box plots of the spatial (B ) and rate (C ) similarities between repeated exposures to an identical journey and task-demand (red), between different journeys within a given task-demand (green), and between different task-demands within a journey (blue) (median, first and third quartiles, minimum, and maximum indicated).
