Asking yourself 'Am I conscious now?' repeatedly through the day tends to turn up the same answer: yes, but now. That suggests awareness may not be a continuous stream, only something that shows up whenever you check. The question is a probe that alters the thing it probes, so first-person inquiry becomes an experiment rather than a report.
We feel that we are continuously experiencing a rich, detailed visual world. Change blindness and inattentional blindness show that we notice large changes only when attention lands on them. So the feeling of a full, continuous stream may be built after the fact whenever we ask what we were aware of, rather than being a record of what was actually experienced.
The 'easy problems' of consciousness, such as discrimination, report and attention, can be solved by describing mechanisms and functions. The hard problem asks why any of that processing is accompanied by subjective experience at all. Blackmore presents this gap as possibly real, or as possibly a sign that our concept of consciousness is confused, and she warns that most theories quietly explain function while claiming to explain experience.
