AA106 should have caught it, the two taxiways are clearly marked with which runway they are intersecting. That said, from a
Post #9 in the link below also has a good diagram of what should have happened vs what actually happened. They missed the turn to Kilo but the turn onto Juliet is probably less than another 30-45° of turn and is the next taxiway immediately after Kilo in the direction they were travelling.
Let's assume they had briefed it correctly. In their minds they had a mental picture of a right hand turn and immediately a runway crossing - that is what they expected to see with their clearance. And that is exactly what their wrong turn also provided to their eyes visually - a right hand turn with an immediate runway crossing. So they saw exactly what they expected to see, but they did not notice it was a different runway. That is not excusable but I can certainly see that as a contributing factor. Our brains/eyes are conditioned to process and interpret things partially on what we expect to see and not necessarily what we actually see. I think that may have played a factor here.
