Sometimes I'll look at a word for too long and I become convinced that it's spelled or pronounced incorrectly.  This happens most frequently with "spider" (I think that should be pronounced "spih-dur" [like "spitter"], not "speye-dur") and happened just now with "finger" ("fin-gur", not "feen-gur").

There's a similar variant to this ([discussed here](http://english.stackexchange.com/q/6170/10411)), but that's related to a word losing it's meaning.  To me, the word just looks incorrectly spelled, or I convince myself that everyone's pronouncing it incorrectly.  Is there a difference between what I'm describing and Semantic Satiation?  If there is a difference, does this one have a name?
