I think I see where the conflict is. I view a certain level attention scaling as effective ignorance where you need evidence of absolute unawareness?
I would look at it this way: I need EEG evidence of unawareness. Operationally, I would define unawareness as a lack of brain activation in a particular area known for a particular effect above baseline.
So if we have activation in Wernicke's area, for example, I would say people read the word.
That being said, we both actually described the traditional Stroop task wrong. I realized it reading tmp's post. Most people have a
very hard time saying blue and many say red.
What the stroop task shows is automaticity in visual processing that overwrites the conscious reading filter. The automatic part of the task is that you accidentally say the colour it is instead of the colour as writen (as red), and the supression effect is the proper reading of the colour (as blue).
I do cognitive neuroscience and problem solving, so we have propositional and procedural variants on the Stroop task where we look at things like automaticity in writing, but the colour task isn't a task that shows this at all.

Interesting; i was scrolling this thread up
from the end of it to catch up, so i just skimmed across the lines.
Without knowing the context, the BLUE thing registered as
'something red' in my head and "blue" very much failed to register at
all. I don't think there was any delay in the process.
That would be doing the experiment wrong. You skimmed a paragraph of content and noted the
emblazoned colour. That's not the Stroop task.
That being said, you also showed the effect as predicted (for the traditional task) - you ignored the content and automatically proccesed the colour, which is more salient re: attention.

I suppose it may put me in that group of
"some who will not". Maybe that's why i have this trouble with finding
common ground with In Exile in this discussion -- he literally perceives
things in different way and focuses on different aspects.
No. You would be wrong. It has nothing to do with me. It has to do with empirical findings in psychology. If you have a problem with anything, it is with the science.
When Maria talked about individual differences in the Stroop task, the explanation isn't that there are two kinds of thought processing ought there but rather one store of cognitive suppresion that people differ in (which may actually tie into things like delay gratification).
