I read somewhere that it takes ten exposures to a new word before you learn it. After reading that, I started tracking how many times I see a new word before I recall what it means. Unsurprisingly, it falls along a distribution, but for harder words it does take me quite a few exposures before learning it. By the time I learn it, the feeling is often recognition that I have trouble with this word, and boredom that it's this word again. =)
