Could it be this
Mono-processing
To avoid overload of sensory information, only one modality is processed
consciously by the brain (though subconsciously a great amount of infor-
mation may get in – ‘accumulation of unknown knowing’ – Williams
1994). The person might focus on one sense, for example, sight, and
might see every minute detail of the object. However, while his vision is
on, the person might lose awareness of any information coming through
other senses. Thus, while the person sees something, he does not hear
anything, and does not feel touch, etc. When the visual stimulus fades out,
the sound could be processed, but then the sound is the only information
the person is dealing with (i.e. disconnected from sight). As the person
focuses on only one modality at a time, the sound may be experienced
louder because it is all the person focuses on (hypersensitivity).
According to the number of senses working at a time the person can be
classified into ‘multi-track’ versus mono-processing (Williams 1996) or
‘being singly channelled’ (Lawson 1999). The ability to receive and
process information via multiple sources can also be referred to as
‘polytropism’, in contrast to ‘monotropism’ (using one channel at a time)
(Lawson 2001; Murray 1992).
Most people use their senses simultaneously. When they are hearing
something, they are still aware of what they see and feel emotionally and
physically, because they are ‘multi-tracked’. For people who work in mono
to process the meaning of what they are listening to while being touched
may be to have no idea where they were being touched or what they
thought or felt about it. To process the location or special significance of
being touched while someone is showing them something means that they
see nothing but meaningless colour and form and movement (Williams
1996).
I have Mono-processing. When I read something out loud I can't understand what I am saying.
Maybe what you have is Mono-processing with another sense.
