Related to my comment on the parent question: is there documentation of specific attention minimization and/or blotting-out effects in immediate sensory processing related to past emotional aversion? I suspect the two of those, despite being listed as separate bullet points in the parent question, should be treated separately…
A more generalized form of this seems like it'd be the kind of dissociation that can occur in e.g. PTSD. Do some PTSD sufferers have sharper sensory issues surrounding the brain refusing to recognize certain stimuli?
