Although not common, there are visual people who look up and to their right when they are recalling memories. Again, we emphasize the importance of baselining.
So, if most visual people look up and to their left when recalling a memory (telling the truth), then it makes sense that most visual people will look up and to their right when they are constructing (lying). Be advised that if you ask your subject to imagine some scenario, they will also look up and to their right. Also, most people will look to their right if they are trying to recall numbers.
But what if your subject is predominantly auditory, a hearing dominant person? Most auditory people will look laterally and to their left when accessing memories. If you've baselined your subject and they look laterally and to their left when answering a question with no consequence to the answer, they will look to their right when they are lying to you.
