The room will usually fool the eye into taking on the aspect of the building material. So if you use the tile vertically, yes, it could make the room look "taller".

Ceiling colors versus wall colors can do the same. If you had a ceiling that was darker than the wall color, the darker color can attract attention, and visually make the ceiling appear to be lower than it is. A lighter colored ceiling can make the ceiling appear higher.

Same with floor. Floor tile in a linear or stacked pattern will pull the eye from one wall to the opposite wall, the shortest distance. Tile on a diagonal can pull the eye on a diagonal, the longer dimension. That can make the room to appear more expansive.

If you're into psycho-babble mind-melding voodoo stuff like that.
