Can Chinese readers scan large amounts of text faster/more accurately than their alphabet-using counterparts?
This research seems to be relevant.

Your question seems to be closely related to rapid reading techniques. Looking on those techniques, you may notice that many of them don't apply to Chinese, simply because logographic writing systems naturally allow rapid reading with no extra training.
There is even an idiom, 一目十行 -- "reading ten lines at the same time"; literally, "one eye ten lines`.


Sub-vocalization, a process of associating a text with its phonetic representation. It slows down reading in any language, but Chinese symbols are always monosyllabic, and the majority of dictionary words consist of only two syllables.
Replacing a sequential word-by-word reading to seeing a whole page at once (or, actually, square blocks of text). Chinese text is naturally a grid by itself.
Related to above, but different, avoiding linear reading. Alphabetic writing systems imply the words aligned horizontally. Your eyes follow a word and it's difficult to follow several lines at once.
Seenig the shape of the wrods, not redaing them in detial. (how many typos did you see here?). In Chinese, you don't look at each stroke or radical, you just get the entire character at once.
Look here: someone can recognize 300-800 characters, but admits that he/she still needs 5-10 seconds to recall a single one.
