In order to locate the possible neural source of the motor content and effortfulness effect for implied motion perception, two separate swLORETA source reconstructions were performed on the difference waves obtained by subtracting the ERPs to static from those elicited by dynamic pictures in two adjacent time windows, 380-430 and 430-480 ms.
Overall, these data suggest that the perceived effortfulness of visually presented actions affects the autonomic response by increasing the heart and respiratory rates as a function of the perceived muscular effort.
To catch this emergence of tension, try to start paying attention to your breathing several times trying to tune in to this transition from effortlessness to effortfulness.
What I mean by this is the effortfulness that stems from supervision, the sudden burden of responsibility that the mind feels as it tunes in to the workings of its own body.
Now, by effortfulness I do not mean "labored breath" or any "shortness of breath."
 - , , suggesting an interesting correlation in perfectly still observers between greater effortfulness of observed actions and increased respiration and heart rates.
 has shown an interesting correlation between greater effortfulness of observed actions (which included weight-lifting, running, walking at increasing weight or speed) and increased respiration rate.
