It wasn't some aggressive form of paralysis followed by induced amnesia. They were standing still for the daily download of information. Note the laughter when they get their daily joke downloaded to them and the way they nonchalantly continued about their business.
I see your point about them all being aware of the download, but disagree with them not being paralyzed by it. They may have been aware of the fact that they will periodically get information downloads, but I don't think they know/knew/could anticipate when it would happen. For everyone to stop so suddenly and completely to me says "unexpected."
I also noted that they all seemed to laugh at the same time, in the exact same manner, as they suddenly proceeded, just as they all simultaneously stopped and remained unaware of their surroundings as they downloaded. All of which seemed exceedingly strange to me, as a viewer, and evidently to the Doctor as well. Not that there was necessarily anything nefarious going on, but something definitely out of the ordinary, which was what piqued the Doctor's curiosity.
If one person had just stopped while downloading, or if they all sort of just stood patiently while downloading, I'm sure it would still have piqued his interest, but the manner in which it was depicted was decidedly strange.
I think we're going to go back and forth on this, though.
In any case, my original point was mainly that I think Jackie's earpieces are different in that they are a two-way connection to Lumic (download/upload), while the "standard" issue are just one-way (download).
