I thought I remember string theory positing more than three dimensions. Does string theory explain our perception of three at human length and time scales?

Yes, in string theory the extra dimensions are very small, leading to three macroscopic dimensions the same way the thinness of a piece of paper leads to two macroscopic dimensions.
