To examine if the perception of obstacle height influenced the action of stepping over the obstacle, the height judgment was compared to toe elevation when stepping over the obstacle in the first and last five obstacle crossing trials.
In this study, perception of obstacle height was evaluated while the participant was standing still, but the participant was moving toward the obstacle when presumably the perception-for-action was being formed in the gait trials.

This paper forms part of a wider set of analyses designed to explore doctors' perceptions of obstacles to returning to work after at least 6 months away from work.
We appreciate that while these analyses emerge from a wider study of doctors perceptions of obstacles to their return to work, doctors who volunteered, may have held with stronger views, either positive or negative about the regulatory process.
This paper makes use of only the crawling mode of locomotion, to improve perception of environmental obstacles.
Hence, the results imply that the traditional navigation aid being used by a participant alters her perception of which obstacles are more challenging to detect.
The breakdown in our public dialogue begins with our inchoate perception of these obstacles: We see the ones we confronted; we simply aren't aware of those we didn't.
"I think that in many instances the perception of the obstacle can often be greater than the obstacle itself".
Waving is thought to be associated with perception and avoidance of obstacles and is thought to be dependent on correct gravity sensing and responsiveness, as mutations in genes associated with gravity sensing disrupt the signal transduction mechanism and abolish the waving phenotype [ 8, 9].
