One useful method is to associate expected taxiways with structures such as terminal buildings, control tower, fingers and so on. For example, Hong Kong has a taxiway running along each side of the control tower, V and W. By using the tower as a visual guide it should be difficult to confuse the two.
Short term memory is also important. If for example, you have two parallel taxiways after vacating the runway, say A and B, you need to remember which is which prior to touchdown. That way you can vacate with minimum delay, without having to first consult a chart. Hope this helps.
